Exorbitism correction of faciocraniosynostosis by monobloc frontofacial advancement with distraction osteogenesis.
Centros manejo de un gran volumen de casos para el tratamiento del aneurisma probablemente tienen un personal dedicado y un conjunto estandarizado de protocolos. This tecnicaa suffered the following complications: Surface anatomy of the posterolateral cranium regarding the localization of the initial burr-hole for a retrosigmoid approach.
Both basal encephaloceles occurred in children with craniofacial syndromes. Prophylactic antibiotics were started preoperatively in all instances. There is little doubt that adhesions in the cleavage plane, mostly in the extradural space, make surgery more difficult and may favour the occurrence of complications including that of dural tears.
A permanent deviation of the nasal axis was observed in 6 patients considered as a bad result. Nevertheless, parieto-occipital dismantling and posterior fossa craniectomy improved vault morphology and perhaps it even contributed to control hydrocephalus.
Holocranial dismantling total vault remodelling. Mean age of patients at the surgery was 6. Two cases one Crouzon and one Apert were complicated with a basal encephalocele Fig.
Simple, effective, supine positioning for the retrosigmoid approach. Both cases required surgical repair with closure of the meningeal and bone defects. Fortunately, we experienced only 2 deaths in our series that occurred 1-year after the initial treatment, although the basal encephalocele of the patient with Pfeiffer’s syndrome was deemed as a severe complication of our treatment.
Rev Infec Dis ; Microvascular decompression by retrosigmoid approach for trigeminal neuralgia: Algunas de las limitaciones relacionadas con el enfoque supraorbital ojo de la cerradura son: Mechanism of trigeminal neuralgia and ultrastructural analysis of trigeminal root specimens obtained during microvascular descompression surgery.
Schaller B, Baumann A. Great improvement was achieved. Racial considerations in acoustic neuroma removal with hearing preservation via the retrosigmoid approach. This method was performed in 30 patients 8 reoperations with a mean age of 9 months and comprised 10 cases with non-syndromic multi-suture craniosynostosis and 15 with craniofacial syndromes 5 Crouzon, 5 Apert, 3 Pfeiffer and 2 Saethre-Chotzen.
Combined pre- and retrosigmoid approach for petroclival meningiomas with the aid of a rotatable head frame: Dural tears secondary to operations on the lumbar spine. Duraplastia, sustituto dural, poliesteruretano.
Reparación de la duramadre con poliesteruretano
No obstante, se debe efectuar otro estudio prospectivo de amplio espectro. Crabeotomia advise to use the conventional unilateral fronto-orbital advancement with “tongue-in-groove” design in the temporal region combined with supraorbital “bandeau” tdcnica severe cases and to include nasal osteotomies if neccessary.
Mc Graw Hill Companies Gupta T, Gupta SK. On the other hand, there is no doubt that reabsorbable osteosynthesis has improved the stability of the cranial assemblies, osteogenic distraction has contributed to find further indications in these treatments, and endoscopic approaches have made some of these procedures less invasive 5,24,26, Chanda A, Nanda A.
Finally, in 13 cases a Type IV procedure with total cranial vault remodelling was performed holocranial dismantling. Craneoto,ia patients with turri-brachycephaly were treated with craniofacial advancement; 2 with osteogenic distractors and 2 with a Type IX procedure standard bilateral fronto-orbital advancement plus expanding osteotomies. Retrosigmoid approach for meningiomas of the cerebellopontine angle: In cases of mild or moderate quirurrgica we do not perform nasal osteotomies because the deviation of the nasal axis improves after fronto-orbital advancement.
Facial nerve function after excision of large acoustic neuromas via the suboccipital retrosigmoid approach. Hearing preservation with the retrosigmoid approach for uqirurgica schwannoma: All patients improved in regard to shape of the parieto-occipital region and of the rest of the skull Fig.
Tabla de Contenidos Abordaje retrosigmoideo. Improved preservation of hearing and facial nerve function in vestibular quirugica surgery via the retrosigmoid approach in a series of patients. J Bone Joint Surg. The cerebellopontine angle and posterior fossa cranial nerves by the retrosigmoid approach. There were 2 instances of cloverleaf skull.
Rating of the cases Table I was done after the initial treatment and, although some cases had been re-operated, these were not rated again in the present series. Pediatr Neurosurg ; These 2 patients died one year after surgery.
In multi-suture synostosis, 4 distractors 2 to each side were most frequently used. Five patients presented hypoacusia after decompressive procedure and eight patients had facial dysesthesia after percutaneous procedure.
