There have been various effective surgical procedures for the treatment of non-syndromic sagittal craniosynostosis, but no definitive guidelines for management have been established. We conducted a study to elucidate the current state of practice and establish a warranted standard of care. An Internet-based study was sent to 180 pediatric neurosurgeons across the country and 102 craniofacial plastic surgeons in fourteen different countries, to collect data for primary indication for surgical management, preference for timing and choice of surgery, and pre-, peri-, and post-operative management options...

BACKGROUND: Hydrocephalus is classified as noncommunicating and communicating based on whether all ventricular and subarachnoid spaces are communicating. Although the diagnosis between the two different states is crucial, it is difficult in certain conditions. In particular, communicating hydrocephalus and noncommunicating hydrocephalus owing to fourth ventricle outlet obstruction are highly misdiagnosed. We describe a case of fourth ventricle outlet obstruction of unknown origin that was initially misdiagnosed as communicating hydrocephalus...

Skull base surgical defects present unique challenges to anatomic and functional reconstruction. Fortunately, many endonasal skull base defects are successfully managed with a variety of local and regional reconstructive techniques. However, when prior surgery or radiotherapy eliminates the use of these local and regional reconstructive options, more elaborate free tissue transfer techniques are required. Managing endoscopic skull base defects of the anterior cranial fossa and clivus is further complicated by the limited access afforded for flap inset...

OBJECTIVE There is a paucity of literature regarding the learning curve associated with performing endoscopic endonasal cranial base surgery. The purpose of this study was to determine to what extent a learning curve might exist for endoscopic endonasal resection in cases of craniopharyngiomas. METHODS A retrospective review was performed for all endoscopic endonasal craniopharyngioma resections performed at Thomas Jefferson University from 2005 to 2015. To assess for a learning curve effect, patients were divided into an early cohort (2005-2009, n = 20) and a late cohort (2010-2015, n = 23)...

Resection remains the mainstay of treatment for craniopharyngiomas with the goal of radical resection, if safely possible, to minimize the rate of recurrence. Endoscopic endonasal and microscopic transcranial surgical approaches have both become standard methods for the treatment for craniopharyngiomas. However, the approach selection paradigm for craniopharyngiomas is still a point of discussion. Choosing the optimal surgical approach can play a significant role in maximizing the extent of resection and surgical outcome while minimizing the risks of potential complications...

This article reviews the normal anatomy and variants of the anterior skull base and sinonasal cavities that are relevant to endoscopic sinus and skull base surgery. Radiologists should be aware of sinonasal anatomy that can be impediments to surgical access and increase risk of vascular or cranial nerve injury during surgery. Imaging features of the paranasal sinuses and anterior skull base pathologies are also discussed.

The cranial base is a complex 3-D region that contains critical neurovascular structures. Pathologies affecting this region represent some of the most challenging lesions to manage due to difficulty with access and risk of significant postoperative morbidity. With the development of expanded endonasal endoscopic approaches, skull base surgeons use the nose and paranasal sinuses as a corridor to access selected ventral skull base lesions. This review discusses high-resolution imaging in the evaluation of patients with skull base lesions considered for endonasal endoscopic surgery, summarizes various expanded endonasal endoscopic approaches, and provides examples of commonly used expanded endonasal endoscopic procedures...

Fronto-ethmoidal meningocoele is a rare congenital condition with protrusion of meninges through anterior cranial fossa into the facial skeleton, surgical repair should be done in order to resolve nasal obstruction, provide a watertight division between sino-nasal and intra-cranial cavities and minimise injury to any CNS contents (Maddalozzo in Issue Otolaryngol Clin N Am 2015). Open approaches may be required but endoscopic endo-nasal repairs can be done in paediatric skull-base defects. A 3 month-old infant with fronto-ethmoidal meningocele operated with endo-nasal approach...

Brainstem cavernous malformations are challenging due to the critical anatomy and potential surgical risks. Anterolateral, lateral, and dorsal surgical approaches provide limited ventral exposure of the brainstem. The authors present a case of a midline ventral pontine cavernous malformation resected through an endoscopic endonasal transclival approach based on minimal brainstem transection, negligible cranial nerve manipulation, and a straightforward trajectory. Technical and reconstruction technique advances in endoscopic endonasal skull base surgery provide a direct, safe, and effective corridor to the brainstem...
