Latest / Pediatrics Now: Cases Updates and Discussions for the Busy Pediatric Practitioner / Neurosurgery Update: Plagiocephaly vs. Craniosynostosis—When to Refer
Transcript
- 0:00As a parent, like, well, less is more. But like in this case,
- 0:03like, well, yes, but actually if there's something more could be better.
- 0:08And if there's something, it will get worse over time. And when we diagnose
- 0:13it early, we can fix it earlier.
- 0:15You can't be too cautious when it comes to your baby's head shape.
- 0:17Exactly. And we have a really nice setup where it's us. We have the head shape
- 0:21clinic. We have our mid-level providers.
- 0:25And the setup that we have at University Health, we see them almost on the same
- 0:30day that we get the phone call.
- 0:32We get them in and we get, when we need to get the imaging, the head CT team
- 0:36gets them in really quickly and there's no sedation required because babies,
- 0:41when they drink milk, they're in their milk coma, they go to sleep and it happens
- 0:44in two minutes and it's done.
- 0:46I think that the most important thing is like when a mom, especially when it's
- 0:50not a first time mom, when moms have multiple kids and when the mom's like, something's wrong.
- 1:11Children's Hospital. Today, I'm thrilled because here in the podcast studio
- 1:16with me is Division Chief of Pediatric Neurosurgery at UT Health San Antonio,
- 1:21Dr. Isabella Tereshevitz.
- 1:24Dr. Tereshevitz, or Dr. T, as you're known, thank you so much for being here
- 1:28in the podcast studio. Thank you for having me.
- 1:31I know you're so busy and you've been working on some big cases,
- 1:35and I so appreciate you taking the time to talk to me. Thank you.
- 1:39So the critical treatment window for infant head shape abnormalities,
- 1:44helmet therapy, and preventing major surgery through early detection is what
- 1:48we're talking about today.
- 1:50Can you explain the difference between positional plagiocephaly and craniosynostosis
- 1:56and why distinguishing between the two is so crucial?
- 2:00Yes. So craniosynostosis is the premature fusion of a suture,
- 2:05which is like a line between bone plates.
- 2:09And when this happens, it creates abnormal increased pressure in the brain and abnormal head shape.
- 2:16And so it is very different than positional plagiocephaly, which is a flatness
- 2:21on the back of the head when the babies sleep on the back of their heads.
- 2:26And so distinguishing a true craniosynostosis is really important because we
- 2:31need to refer them to a pediatric neurosurgeon for an early intervention.
- 2:36We like to do those surgeries at three to four months of age so we can offer
- 2:41a minimally invasive surgery.
- 2:43Now, sometimes when they're not diagnosed early, we get them later for the diagnosis.
- 2:48And when we get them later, saying at six, seven, eight months of age,
- 2:52then we have to do a bigger surgery and we cannot offer the minimally invasive surgery anymore.
- 2:58And so it's important to diagnose those patients early on so we can do a smaller
- 3:04incision and patients can stay in the hospital for a shorter period of time.
- 3:08They will not require a big blood transfusion. And I think overall,
- 3:13it's just a better surgery to offer. Because it's an endoscopic?
- 3:17Yes, immunally invasive and endoscopic depending on the suture that is involved.
- 3:21We use an endoscope for the sagittal suture when it's involved.
- 3:24And when it's a shorter suture, such as metopic and coronal switchers,
- 3:27we don't have to use the endoscope, but we use minimally invasive instruments.
- 3:32So, Isabella, who is responsible or who is it up to to make that crucial decision
- 3:39that this baby needs to get in and see a neurosurgeon quickly?
- 3:42Is it the newborn team, the parent, the pediatrician?
- 3:46I think it's a combination of multiple people involved in that child's care.
- 3:51I would say initially, whomever feels like there's something abnormal looking should send the baby to,
- 4:00a head-shaped clinic or the orthotics clinic or the craniofacial clinic or the neurosurgery clinic.
- 4:07So I would not wait because anytime you have a craniosynostosis concern,
- 4:11it won't go away with time. It will just get worse.
- 4:15And so we have a head-shaped clinic here at UH. we have a craniofacial clinic
- 4:19that is nationally recognized.
- 4:21We also have the helmet clinic, so the orthotics clinic for positional plagiocephaly,
- 4:26and that fits our kiddos for helmets after the craniosynostosis surgery is done.
- 4:32So anytime that a child has an abnormal head shape, I would say the parents
- 4:37might be concerned, the pediatrician, if the pediatrician is concerned,
- 4:40if the nursery doctor that sees the babies, the pediatrician sees the babies
- 4:44initially should send us a referral.
- 4:46Anyone, a PT that works with a child, an OT that works with a child has a concern.
- 4:52Let's just send that referral into our coordinator and we'll see the child sometimes on the same day.
- 4:58So you just met my daughter who's in college and after 35 hours of labor 20
- 5:05years ago, so she had to be vacuumed out.
- 5:09So she had kind of a cone head when she came out, which was a little alarming,
- 5:13but it turned out to be fine. So that's totally...
- 5:17Yes, that's totally fine. That goes away after a week or so.
- 5:21But a craniosynostosis is something that doesn't go away because that suture is fused.
- 5:26And as the head grows, that abnormality just gets worse and worse.
- 5:30So whenever you feel a ridge or whenever the abnormal head shape gets more accentuated,
- 5:36then the patient should be referred to neurosurgery.
- 5:38And there's a simple way of seeing this.
- 5:41I would say anytime a parent or a practitioner looks at the patient's head from
- 5:46above and it's either a head, so normally a head should be pretty much round.
- 5:51And we have a fontanelle that's right behind the hairline or the imaginary hairline
- 5:56if the baby's completely bald.
- 5:58So we have a soft spot there. And so the metopic suture is the suture that we
- 6:02have splitting the forehead in half.
- 6:06And so if looking from above, the forehead is not flat but has a triangular.
- 6:11Head shape, pointy head shape, that's not normal. We shouldn't have a head shape like that.
- 6:16If looking from above, the head shape looks like a football,
- 6:21very long, oblong head shape, that's not normal either.
- 6:24And then if we look at the face of the baby and the forehead is flat,
- 6:30the nose is crooked, and the ears are asymmetrical, that's also not normal.
- 6:34It's not going to go away on its own. And if initially, yes,
- 6:38for sure, the pediatrician will see the baby very frequently because you have
- 6:42to make sure that the infant is keeping its weight and, you know, all those things.
- 6:47You see that baby as a pediatrician very, very often.
- 6:50If it gets worse or if you're keeping track of that and it's not getting better,
- 6:54then you send that baby to a head shape clinic.
- 6:57So Isabella, what's the difference between a baby who comes to you at three
- 7:01months versus 12 months?
- 7:03So at three months, we will offer an endoscopic minimally invasive surgery,
- 7:07and at 12 months, it's a vault surgery.
- 7:09So the vault surgery is an ear-to-ear incision.
- 7:14And we do a planned vault surgery, which means that we're expanding the entire
- 7:20skull to create more volume because we miss that window of the baby's head growth.
- 7:26And we will create an in-situ volume expansion. And then after that surgery,
- 7:32the baby will not need to wear a helmet because we would have expanded that
- 7:37volume right away in surgery.
- 7:39A three-month-old baby will just remove that suture and close this small incision
- 7:45and then put the baby in a helmet with gaps within the helmet to allow head
- 7:49growth in a specific direction.
- 7:51It's like a mold that the helmet will have to be worn for 23 hours a day for
- 7:5612 months, and then the head will grow in a specific direction and create,
- 8:04that added volume that the baby needs for his head.
- 8:09Are these abnormalities usually noticeable at birth, like with my daughters
- 8:13that turned out to be fine, or do they develop over time?
- 8:17They're pretty much noticeable. When you know what you're looking for,
- 8:20I see them as soon as I walk into my clinic room when I see those patients. Really?
- 8:27So, yes. And that's why I go out to clinic practices and I show them those skull
- 8:32models so they can, once you see one, you know exactly what you're looking at.
- 8:36Sometimes it's kind of hard to understand what you're looking at.
- 8:40There's something not right with that head shape. But once you see one,
- 8:44you absolutely know what you're looking at.
- 8:46But what I've described earlier with the triangular forehead,
- 8:52so the most frequent head abnormality is sagittal and then it's metopic.
- 8:56So when you look from above, it's that football long head shape.
- 8:59That's sagittal craniosynostosis, also known as scaphocephaly.
- 9:03And the metopic is the second most prevalent one.
- 9:06Metopic craniosynostosis or trigonocephaly because it looks like a triangular
- 9:10forehead. Those are the two most frequent ones that we see in kiddos.
- 9:15So are there subtle findings at birth that clinicians sometimes dismiss as molding
- 9:21from delivery? I know a lot of our listeners see 40 patients a day.
- 9:25They've got so many things going on and of course no one wants to miss anything. Sure.
- 9:30Well, metopicraniosynostosis, you can't really miss this for molding because
- 9:34when you have a triangular forehead.
- 9:37And it's a clear triangle. It's a clear triangle. And maybe what can be done
- 9:42is if you're questioning it, you know, chat GPT, Google it and look for images
- 9:48because it's very striking.
- 9:50Scaphalocephaly sometimes can be mistaken for molding.
- 9:54I would say if you are the practitioner and you're not sure,
- 9:58you can put your fingers over the midline and feel a ridge. There's a clear
- 10:01ridge, a bony ridge that can be felt when the suture is fused.
- 10:05You don't have that in normal babies that have simple molding. Mm-hmm.
- 10:10So in your experience as a neurosurgeon,
- 10:14at what well-child visit do these concerns most commonly emerge?
- 10:18They're pretty much there from birth. Really?
- 10:22Okay. Yes. So I would say, especially when the parents are concerned,
- 10:28I would listen to those concerns.
- 10:30And as soon as they are voiced to the pediatrician, I would send them to the
- 10:36head-shaped clinic and the craniofacial
- 10:37clinic. We're always happy to see those babies in the families.
- 10:41And if it's normal, I'm happy to reassure a family.
- 10:44So to my next question, when should a pediatrician stop assuming a head shape
- 10:48issue will round out on its own? Never? Never.
- 10:52That's it. I mean, that relieves a lot of stress. Yes. And the funny thing is
- 10:57that I give my cell phone number to all the pediatricians in our catchment area, in our community.
- 11:03So if they want to text me, if they want to text our coordinator,
- 11:07they can call us. We will see those families as soon as we can,
- 11:10and we see them within that same week, and we'll reassure the families,
- 11:14and everyone will be happy.
- 11:16And I'll put your contact information, whatever we can, in the text for the podcast.
- 11:21And another message I know when I saw one of the talks you gave recently is.
- 11:27Don't do imaging on your own.
- 11:28So the main message that I want to send is don't do x-rays because x-rays is
- 11:36something that is not recommended.
- 11:39When you do x-rays for a craniosynostosis, it's two, three views,
- 11:43and that ends up being more radiation than a 3D low radiation protocol.
- 11:48And so just send the babies to us. I can recognize a craniosynostosis diagnosis
- 11:54with just looking at the patient clinically.
- 11:57And then we can order the CT even when the patient sees us in clinic,
- 12:02especially when the tiny babies, as I said, when the moms either feed them or
- 12:07give them a bottle, they will sleep for a couple of minutes.
- 12:10And then we can slide them in the CT scanner for a low radiation protocol.
- 12:14Call and then it's done on the same day and we get the confirmation for the
- 12:20diagnosis very quickly.
- 12:22And that helps us plan our surgery as well.
- 12:25Are there any other red flags we didn't go over that would prompt an immediate referral?
- 12:31Any regression of milestones that can happen because of increased intracranial pressure.
- 12:38And are there any certain head-shaped patterns that are commonly missed?
- 12:42Is the triangle forehead commonly missed? The football, it's a horizontal football
- 12:48head looking down, right? So it's an elongated head shape.
- 12:52Sometimes the bicoronal craniosynostosis is missed.
- 12:58It doesn't happen very often, but I have seen several ones that have been missed. It looks...
- 13:06It looks like a square head shape. Again, it's an abnormal head shape.
- 13:11When you look at that baby compared to their siblings, it's absolutely not normal.
- 13:17So the mom was concerned. The pediatrician didn't really know what to do with
- 13:20that head shape, but ended up
- 13:22sending the patient to us because there was something not normal looking.
- 13:27And it was early at two months, so ended up being referred to us early and having
- 13:33a minimally invasive surgery.
- 13:35So I applaud the pediatrician for recognizing that. So I think that anytime
- 13:39that there's something that is not normal looking, just send it to us and we'll
- 13:42be happy to take care of it.
- 13:44How much should clinicians rely on head circumference versus head shape?
- 13:49So a single suture craniosynostosis, if it's just one suture that is closed,
- 13:55the rest of the sutures will overcompensate. And most of the times the head
- 13:59circumference will be normal versus slightly higher.
- 14:03So just looking at that, I don't think we can make a diagnosis.
- 14:09Multiple suture craniosynostosis. So kiddos that have a syndrome,
- 14:13they tend to have a smaller head.
- 14:16So just one suture, you can't say much, but multiple sutures,
- 14:20the head will be small, and then
- 14:22you have an increased risk of having even more pressure in your brain.
- 14:28Let's talk about helmets. When is a helmet appropriate versus unnecessary?
- 14:32So for the minimally invasive surgeries, you need a helmet to guide the head
- 14:39growth in a specific direction, And also we remove a significant amount of bone
- 14:43and then it's for protection until the bone grows.
- 14:46So after the surgery. Absolutely.
- 14:49For the big vault surgeries, we don't need a helmet because we plate the bones
- 14:53internally. So it's solid enough that the patient does not need a helmet.
- 14:58Now for positional plagiocephaly, which is when the head is flat because of
- 15:04positioning. Or flat head syndrome. Exactly.
- 15:07When you have a flat head because of sleeping on one side and because you have
- 15:11torticollis, so when you have your neck is crooked and you need physical therapy
- 15:14to straighten your neck and then you have your flat head, then you will need
- 15:18a helmet sometimes to kind of help reposition,
- 15:21your head and grow your head in the other direction.
- 15:24So those are the conditions when you will need a helmet.
- 15:28Can you tell us about the ideal age window for helmet therapy to be the most effective?
- 15:33So when you are very young, because the skull is very pliable and very soft,
- 15:38the softer the skull, the better you will respond to helmet therapy.
- 15:43If you're older, closer to 8, 9, 10 months of age, then your bone,
- 15:49as a baby, your bone is not soft anymore as much as when you're younger,
- 15:53and then the helmet therapy is not going to work as well.
- 15:58So as a pediatrician, if you see a flathead at 10 months of age and you're referring
- 16:02to the helmet therapy group, most probably they will tell you,
- 16:06well, at 10, 11 months, if you have a flathead, it's pretty much what your head
- 16:11will look like because the helmet therapy won't work.
- 16:14Really? So if you do find a patient that has a flat head and the family cannot
- 16:21counterposition and do the counterpositioning measures to help,
- 16:25remold the head with just simple counterpositioning, then send to the helmet
- 16:29therapy group early on so they can work on the helmet therapy being effective,
- 16:34early, early on when the babies are young, when the skull is soft,
- 16:38and then there's a lot of growth potential in the skull and the brain.
- 16:43Otherwise, when they're older, the helmet won't work.
- 16:46And we will have an episode on our sister podcast, Pediatrics Now for Parents,
- 16:51and we'll mention tummy time. I know our pediatrician listeners,
- 16:55of course, know how crucial tummy time is. Absolutely.
- 16:59You can't stress that too much with a patient, right?
- 17:03Absolutely. Tummy time is important, and especially for kiddos that have torticollis,
- 17:07I tell the families, PT will show you how to stretch the neck.
- 17:10Every time you do a diaper change, stretch the neck because that's also very
- 17:14important. Tummy time is also important for them to learn how to move their
- 17:18neck, how to have a stronger core.
- 17:21And all of these things are important for the fat head.
- 17:25Are some babies mistakenly sent for helmets when they actually have craniosynostosis?
- 17:30Yes, yes. And that's when our partners within the orthotics team send those
- 17:36babies back to me for a diagnosis of craniosynostosis.
- 17:40What do you wish pediatricians knew about timing referrals for helmet therapy?
- 17:44Timing is crucial. So the earliest the time a diagnosis, the better it is for
- 17:51outcomes and for a smaller surgery.
- 17:55And if you're unsure refer absolutely the sooner the better.
- 18:01We talked about imaging so it doesn't you don't really need any x-ray just send,
- 18:08never x-ray absolutely do not order any x-rays if there's one thing i would
- 18:13want everyone to remember from this podcast is when in doubt send to neurosurgery,
- 18:19and when in doubt do not order x-rays just send to neurosurgery we will be happy
- 18:24to see the patient in our head-shaped clinic, in our orthotics clinic,
- 18:28in our craniofacial clinic, and we will take care of the imaging.
- 18:32Because they also don't want to send a patient unnecessarily too,
- 18:37but in this case, just send. There's no such thing as unnecessarily. That's a good point.
- 18:43And there's no other imaging that they should try to get? No.
- 18:47Can you tell us just quickly what actually changes anatomically once the treatment window is missed?
- 18:54For the minimally invasive?
- 18:56So if I cannot do the minimally invasive, then I will do the bigger surgery.
- 19:00And again, we are an expert center for any type of craniocinostosis.
- 19:05So we have amazing results with the bigger surgery as well.
- 19:09So I'm just thinking with my parent hat right now, if this was my child,
- 19:14I would want the minimally invasive just for the length of stay in the hospital,
- 19:21for the minimally invasiveness of it, the smaller incisions.
- 19:26And, you know, in the future, when that child, when the mom and the child or,
- 19:31the dad and the child are at HEB shopping, no one sees those incisions,
- 19:35right? So it's just nicer, I think, overall.
- 19:39No one even knows that they've had surgery because those incisions, you can't see them.
- 19:44So if this is something that we could offer to a family, that's what I would want for my family.
- 19:50So I would love to offer this to any family that has a craniosynostosis condition.
- 19:54Now, if they come to us later, and I've had patients that came to us at 10 months,
- 20:0012 months, 2 years, 3 years, even six years with a craniosynostosis condition that required surgery.
- 20:05So we've done it at that age, but it requires a bigger incision and it's a bigger surgery.
- 20:11And patients have done great and they've had amazing outcomes,
- 20:15but it is a big incision. It's from one ear to the other. It's a wavy incision.
- 20:20And for the rest of your life, there is a scar that is more visible.
- 20:25Much, much bigger recovery, longer stay in the hospital, more blood loss,
- 20:30and it's a more difficult recovery.
- 20:32So how do you cancel families who think the asymmetry is just cosmetic?
- 20:39So multiple articles have been published showing that it is related to increased
- 20:45intracranial pressure.
- 20:47And so to quote the numbers, for single suture craniosynostosis,
- 20:52kids have abnormal pressure in at least 45% of the cases. Which kid will have it? We don't know.
- 20:59And what we have seen in our patient population is that once we do the surgery,
- 21:05after several months, when they come and see us in clinic, they just catch up
- 21:09on their milestones and they just do so much better.
- 21:12So which parent would not want that?
- 21:18And craniose nososies patients have, you know, research has shown that they
- 21:23have issues with speech, developmental delays. So this is associated with intracranial pressure.
- 21:28So when you open up those sutures and you relieve that pressure,
- 21:32everything kind of falls into place and gets better.
- 21:36What's the biggest misconception parents may have about infant head shape?
- 21:41Do you find that, moreover, it seems like it'll probably be fine thinking that
- 21:46when it's not? No, I think that they come to a neurosurgery office and they
- 21:49think it's going to be brain surgery, when technically it's bone surgery.
- 21:53So it's not as dramatic, but it is a serious surgery.
- 21:58And the other thing that we tell them is that we have a multidisciplinary team.
- 22:03It's the craniofacial team where you are followed for the first five years of your child's life.
- 22:09And you have a multidisciplinary team that will track the milestones and the
- 22:14outcomes for the first five years. And at some point, you will get a developmental
- 22:19assessment, a speech therapy assessment.
- 22:23You know, a dentist will be following you, an orthodontist will be following
- 22:26you, ENT will be following you, plastics, OMFS, neurosurgery.
- 22:30So it's a global team, and that team has specific things that we're following
- 22:36to make sure that you're followed in a specific way, that everything is known.
- 22:45To send you to referrals when you need specific services to make sure that everything is done correctly.
- 22:51What gives you hope about awareness and early detection improving? What gives me hope?
- 22:57I mean, when I see the outcomes of our patients, I think that we're offering
- 23:03an amazing service line to our patient population.
- 23:05And then when I see early referrals, when I see kiddos that come in to us when
- 23:10they're two weeks old, three weeks old, I feel like our pediatricians are recognizing
- 23:16the diagnosis early on and it's working.
- 23:21What inspired you to become a neurosurgeon? It must be so fulfilling.
- 23:25Every day you're helping a child, helping a baby to have a much better life.
- 23:31You know, I thought about this recently because initially I wanted to be a fashion
- 23:34designer. Oh, really? Yes. Because you traveled to Paris, I hear, to shop.
- 23:40I worked, I studied in Paris, but no. You did? I did. You studied fashion? No, no, no medicine.
- 23:48But I really wanted to do craniofacial. Once I was in medicine,
- 23:53that was my thing. So craniofacial is my passion. And there you go.
- 23:56You're just like, this is it. I do arts and crafts with heads. I make them pretty.
- 24:02So it's an art form. Yes. And then you also, I know you did a brain surgery
- 24:08recently for a tumor. You do that as well. We do that. We do tethered cords
- 24:12and spina bifida. We do a lot of trauma.
- 24:15My partner and I, we take care of tethered cords. We do a lot of spine trauma,
- 24:19brain trauma, tumors, hydrocephalus.
- 24:22We just take care of it all.
- 24:24And we have a team of female pediatric neurosurgeons. Absolutely.
- 24:30That's pretty awesome. I like to promote on Pediatrics Now having a life outside of medicine.
- 24:35Do you want to mention a couple of things or what you like to do that helps you unplug?
- 24:40I don't say balance anymore because what is balance? Who's balance?
- 24:44Well, I have a blended family. We have four kids.
- 24:49I also am a mom of a child with special needs. So I understand families that
- 24:54have challenging medical situations.
- 24:57And so what do I do to unplug? I have a Great Dane, a big dog.
- 25:02We also go to the ranch once in a while. We travel. And where's your ranch?
- 25:06Is that in Texas? Yorktown, yes.
