Bended bone cutting scissors are used to cut the bone strip from the posterior incision to the front, while the endoscope is used from the anterior incision to visualize and control the direction of cutting, protecting the underlying dura with the footplate. With our current experience, we actively advise this treatment to any craniosynostosis patient under the age of 4 months, but for patients aged 4–5 months with moderate-to-severe craniosynostosis (especially plagiocephaly and trigonocephaly), we inform parents that this treatment may not be sufficient and cranial vault reconstruction techniques may have to be performed at a later stage. For trigonocephaly, brachycephaly, and plagiocephaly, a two-piece plastic helmet is used [ Figure 5 ]. One week after the surgery, a plaster imprint of the skull is taken, which serves as an initial template for the fabrication of the custom-made helmet and helmet therapy starts within 2 weeks after surgery. How is craniosynostosis treated? 2011. 1-888-572-5526. At the pterion, some thick, cancellous bone can be encountered which may be responsible for some venous bleeding. Keywords: Craniosynostosis, endoscopy, helmet, minimal invasive, surgical technique. Metopic Synostosis: Triangular. Sometimes this will demand simultaneous progressive craniectomy of the suture while performing the dura dissection. • Metopic craniosynostosis or premature fusion of the sutures in the front of the head occurs in about fifteen percent of babies with craniosynostosis. None of our patients need ICU monitoring postoperatively and almost all patients are dismissed the day after the surgery. Antibiotic profylaxis consists of 25 mg/kg cefazolin i.v. 2013. 32: 331-8, 26. However, this time frame is dependent on the age of your baby and severity of craniosynostosis. We agree fully with Hankinson et al. Cushioning is used to to prevent the infant head from further flattening when tilted or resting on a flat surface. Note how forehead comes to a central point and there is constriction at both sides of the forehead. J Neurosurg. 2012. Brain growth continues, giving the head a misshapen appearance.Craniosynostosis usually involves fusion of a single cranial suture, but can involve more than one of the sutures in your baby's skull (complex cranio… 50: 1382-5, 25. Craniosynostosis presents with different clinical findings depending on the extent and number of … There are diff… J Neurosurg Pediatr. 37: 351-70, 29. [ 6 ] This is in agreement with reports by other centers treating large numbers of patients with EACS. Therefore, early referral to the neurosurgeon is of paramount importance. Fax: 210-358-8576, © 2020 University Health System Children’s Health | Craniosynostosis Surgery in South Texas. Most babies are born with a skull made up of several bony plates that are not yet fused together by bone, but are joined together by soft tissue. Jimenez DF, Barone CM. 10: 310-4, 16. Compt Rend Seances Acad Sci. Spring expansion, internal and external distraction, and orbitofrontal advancement may all be combined with EACS, wherein the combination of two techniques allows further improvement of the result. [ 5 ] The outcomes of these techniques do not depend on postoperative brain expansion and are therefore more predictable than simple or extended craniectomy procedures. This would make the helmet therapy more reliable and predictable, with easier, planned, adaptations. Early closure of this suture may cause a prominent ridge running down the forehead. Metopic synostosis: The suture from the nasal bridge passing through the middle of the forehead to wards the sagittal suture is called a metopic suture. San Antonio, Texas 78229 Organogenesis. Jimenez DF, Barone CM. Two skin incisions of approximately 4 cm are used: one 2–3 cm behind the most posterior point of the anterior fontanel, and the second one 2–3 cm anterior of the posterior fontanel. After this, FloSeal® Matrix Hemostatic Sealant is administered for hemostasis. Sgouros S. Skull vault growth in craniosynostosis. who stated “Until a satisfactory craniometric method or group of methods is established, it will be difficult to meaningfully compare the outcomes of the myriad operative techniques currently available for the treatment of single suture craniosynostosis,” and by extension multisuture craniosynostosis. Childs Nerv Syst. [ 6 29 32 ]. In many cases, initial skull re-shaping surgery takes place within the first few years of life. After this, FloSeal® Matrix Hemostatic Sealant is administered for hemostasis. [ 10 14 38 ] Tessier introduced pioneering techniques for the treatment of craniosynostosis that led to significant improvements in cosmetic outcomes, particularly for those with facial abnormalities. A small compressive head bandage is used for 24 h. 3D scan showing extent of craniectomy in plagiocephaly. Creating a normative database of age-specific 3D geometrical data, bone density and bone thickness of the developing skull: A pilot study. Curr Opin Otolaryngol Head Neck Surg. Craniosynostosis requires evaluation by specialists, such as a pediatric neurosurgeon or plastic surgeon. 1998. Case report. This is usually very easy as the dura mater is hardly attached to a synostotic suture, but can be tricky in case of a deep and sharp bony ridge as is often the case in trigonocephaly. The perfect visualization of the dura and operative field by the endoscope in conjunct with a parallel positioned aspirator to clear any blood allows a safe dissection of the dura without the occurrence of dural tears although the frontal bone and synostotic suture often present with deep and sharp bony ridges. Endoscopically assisted versus open repair of sagittal craniosynostosis: The St. Louis Children's Hospital experience. Senarath-Yapa K, Chung MT, McArdle A, Wong VW, Quarto N, Longaker MT. 28: 1429-32, 18. 41: 829-53, 37. 2012. Then, the endoscope is introduced and dura dissection from the overlying bone is performed up to the pterion. Although only roughly one-third of all parents responded, results are mainly in favor for the helmet therapy. Thick black line indicates skin incision, grey area depicts craniectomy size. This resolves the need for constructing a new helmet for a local change, while still being able to guide local skull growth. Early operation in premature cranial synostosis for the prevention of blindness and other sequelae. By guiding the cranial growth in three dimensions, the fast developing and growing brain can act as a very effective internal distractor once suturectomy is performed. Helmet guides and promotes growth to a central point and there is always perfect visualization of the forehead viewed.
