Anterior skull base operations are complex surgical procedures that are performed to treat serious and complicated diseases. Despite significant advances in surgical techniques, complications are relatively frequent and can be serious. Endoscopic skull base surgery seems to be associated with less complications than open techniques. Different classifications aimed at categorizing these complications have been suggested, the use of which can be recommended when reporting complication rates. The most relevant and frequent complications of anterior skull base surgery are hemorrhage, cerebrospinal fluid (CSF) leak, meningitis, and cranial nerve injury...

Objectives  Ideal treatment of craniopharyngiomas is still controversial. Radiotherapy (RT) is considered effective for recurrences or after subtotal tumor removal (STR). About 40 to 50% of patients may experience tumor cyst expansion soon after RT; in these cases, the role of salvage surgery is debated. Design  Operative video. Setting  Tertiary care center. Participants  An 11-year-old boy diagnosed with persistent craniopharyngioma. In 2015, the patient underwent right frontotemporal craniotomy for STR at another center, complicated by panhypopituitarism...

OBJECTIVE Epidermoid and dermoid cysts may be found along the cranial base and are commonly resected via open transcranial approaches. The use of endoscopic endonasal approaches for resection of these tumors has been rarely reported. METHODS The authors retrospectively reviewed the medical records of 21 patients who underwent endoscopic endonasal surgery for epidermoid and dermoid cyst resection at the University of Pittsburgh Medical Center between January 2005 and June 2014. Surgical outcomes and variables that might affect the extent of resection and complications were analyzed...

BACKGROUND: Nontraumatic pseudoaneurysms of the cranial base are rare and present unique diagnostic and treatment dilemmas compared with both true aneurysms and pseudoaneurysms outside of the cranial base. There is a dearth of knowledge regarding the management of these complicated lesions. METHODS: Nontraumatic pseudoaneurysms of the cranial base internal carotid artery (ICA) were retrospectively identified at the University of Pittsburgh Medical Center through a key word search of cranial base cases from 2010 to 2017...

BACKGROUND: Premature fusion of the metopic suture leads to a range of clinical presentations, with more severe patients presenting characteristically with trigonocephaly. Endoscopic-assisted correction of craniosynostosis is emerging as an alternative to the gold-standard open cranial vault remodeling. While there are several documented benefits of endoscopic correction, the management of craniosynostosis varies widely in the literature with little consensus as to the preferred timing and surgical technique for repair...

Objective Vestibular schwannoma (VS) is a benign tumor of the lateral skull base. Different microscopic surgical techniques are described in literature: the retrosigmoid and translabyrinthine approaches are used to treat big tumors located in the cerebellopontine angle, and the middle cranial fossa approach is utilized for small tumors with good hearing preservation. The expanded transcanal transpromontorial (ExpTT) approach is a combined microscopic-endoscopic technique previously indicated for Koos stage I and II VS and now proposed for larger VS, up to 3 cm in diameter, with linear progression into the cerebellopontine angle and touching the brainstem...

OBJECTIVE: Skull base meningiomas carry a nonnegligible risk of recurrence. In particular, those arising from the sphenoid wings or middle cranial fossa penetrate into extracranial regions, uncommonly showing massive expansion into the craniofacial regions on recurrence. The role of endoscopic endonasal surgery for those intractable lesions remains unclear. METHODS: We performed endoscopic endonasal craniofacial surgery for 8 recurrent meningiomas invading into the pterygopalatine fossa, infratemporal fossa, nasopharynx, paranasal sinus, or orbit, comprising 2 meningothelial and 1 fibrous meningiomas (World Health Organization [WHO] grade I), 3 atypical and 1 clear cell meningiomas (grade II), and 1 anaplastic meningioma (grade III)...

REVIEW

Non-functional pituitary adenomas (NFPAs) are benign tumors of the pituitary gland that do not over-secrete hormonal products, therefore, they are generally detected through symptoms of mass effect, including headache, vision loss, or hypopituitarism. There are multiple pathological subtypes of NFPAs, such as null cell adenomas, silent gonadotrophs, silent somatotrophs, silent corticotrophs, and silent subtype 3, all of which can be classified based on immunohistochemical studies and electron microscopy. Despite these numerous pathological subtypes, surgical resection remains the first-line treatment for NFPAs...

Meningiomas represent the most common primary intracranial neoplasm treated by neurosurgeons. Although multimodal treatment of meningiomas includes surgery, radiation-based treatments, and occasionally medical therapy, surgery remains the mainstay of treatment for most symptomatic meningiomas. Because of the intricate relationship of the dura mater and arachnoid mater with the central nervous system and cranial nerves, meningiomas can arise anywhere along the skull base or convexities, and occasionally even within the ventricular system, thereby mandating a catalog of surgical approaches that neurosurgeons may employ to individualize treatment for patients...
