“…Trigeminal schwannomas (TSs) are the most common skull‐base schwannomas after vestibular schwannomas and account for up to 0.36% of all intracranial neoplasms and 8% of skull‐base schwannomas . Most of them develop in the Gasserian ganglion, but they can occur anywhere along the course of the trigeminal root, ganglion, and peripheral branches.…”

“…Most of them develop in the Gasserian ganglion, but they can occur anywhere along the course of the trigeminal root, ganglion, and peripheral branches. Therefore, they can be intradural, interdural, and extradural, can exist in the posterior fossa and middle fossa/Meckel's cave, and extend along V1 into the orbit, V2 into the pterygopalatine fossa (PPF), and V3 into the infratemporal fossa …”

“…Other uses of the endoscope for the resection of TS have also been described. Haidar et al . described 2 cases of infratemporal fossa schwannomas that were completely resected using minimally‐invasive approaches: the first case using an open preauricular subtemporal approach and the second case using a purely endoscopic transnasal approach.…”

“…In larger reported series, either permanent or transient postoperative deterioration in neurological function, including trigeminal neuropathy, abducens nerve palsy, and trigeminal neuralgia, was experienced. When microsurgery alone is applied, up to 85% of cases can be safely resected, with minor complications reported . The most challenging type is the dumbbell‐shaped tumor that crosses the petrous apex to occupy the posterior and middle cranial fossa or has both intracranial and extracranial extension …”

Background Endoscopic skull‐base surgery (ESBS) is employed in the management of diverse skull‐base pathologies. Paralleling the increased utilization of ESBS, the literature in this field has expanded rapidly. However, the rarity of these diseases, the inherent challenges of surgical studies, and the continued learning curve in ESBS have resulted in significant variability in the quality of the literature. To consolidate and critically appraise the available literature, experts in skull‐base surgery have produced the International Consensus Statement on Endoscopic Skull‐Base Surgery (ICAR:ESBS). Methods Using previously described methodology, topics spanning the breadth of ESBS were identified and assigned a literature review, evidence‐based review or evidence‐based review with recommendations format. Subsequently, each topic was written and then reviewed by skull‐base surgeons in both neurosurgery and otolaryngology. Following this iterative review process, the ICAR:ESBS document was synthesized and reviewed by all authors for consensus. Results The ICAR:ESBS document addresses the role of ESBS in primary cerebrospinal fluid (CSF) rhinorrhea, intradural tumors, benign skull‐base and orbital pathology, sinonasal malignancies, and clival lesions. Additionally, specific challenges in ESBS including endoscopic reconstruction and complication management were evaluated. Conclusion A critical review of the literature in ESBS demonstrates at least the equivalency of ESBS with alternative approaches in pathologies such as CSF rhinorrhea and pituitary adenoma as well as improved reconstructive techniques in reducing CSF leaks. Evidence‐based recommendations are limited in other pathologies and these significant knowledge gaps call upon the skull‐base community to embrace these opportunities and collaboratively address these shortcomings.

Intracranial melanotic schwannoma is quite rare, and involvement of the trigeminal nerve is even rarer. Early diagnosis and surgical excision are the mainstays of management. These tumors have a high tendency to recur and there is high possibility of metastasis. Adjuvant radiotherapy should be considered since the prognosis is uncertain. A 23-year-old man started developing numbness over the left side of the forehead 9 months ago that progressed to involve the ipsilateral cheek. The patient started having diplopia on looking to the left side 8 months ago. His relatives noticed a change in his voice 1 month ago and he developed weakness in the right upper and lower limbs, which was gradually progressive. The patient had slight difficulty swallowing. After examination, we found involvement of multiple cranial nerves with pyramidal signs. Magnetic resonance imaging (MRI) was suggestive of an extra-axial lesion in the left cerebellopontine angle extending into the middle cranial fossa, which was having high T1 and T2 signal loss with contrast enhancement. We achieved near-total excision of the tumor via a subtemporal extradural approach. Trigeminal melanotic schwannoma is a rare occurrence constituting melanin-producing cells and Schwann cells. Rapid progression of symptoms and signs should prompt the suspicion of the possible malignant nature of the pathology. Extradural skull base approaches reduce the risk of postoperative deficits. Differentiating melanotic schwannoma from malignant melanoma is of utmost importance in planning of management.
