Schwannomas are benign tumours derived from Schwann cells of the peripheral nerve sheaths. A schwannoma arising in the external auditory canal (EAC) is rare, with few cases reported in the literature. These tumours present a unique challenge and should be considered when patients present with persistent ear symptoms in the absence of common otological pathology.

Article Synopsis
- - Schwannomas are benign tumors that arise from Schwann cells, with vestibular schwannomas being common in ENT, although rare cases exist in the head and neck region.
- - A 13-year-old girl had a chronic swelling in her left cheek that caused aesthetic concerns, and an ultrasound identified the growth as a subcutaneous cyst.
- - Surgical excision was performed through an intraoral incision, and histological analysis confirmed the tumor as a schwannoma, emphasizing that such tumors, while usually benign, can occur in the facial area and require surgical removal for treatment.

Article Synopsis
- Recent studies suggest that some vestibular schwannomas (tumors) may not originate solely from the vestibular nerve of the eighth cranial nerve, which raises new questions about their nature.
- A case-control study found that vestibular evoked myogenic potentials (VEMPs) measured through galvanic vestibular stimulation (GVS) were lower in patients with vestibular schwannoma compared to healthy controls, particularly as tumor size increased.
- The findings indicate that GVS VEMPs can help differentiate between types of vestibular lesions and might provide insights into the relationship between the tumor’s origin and the remaining function of the vestibular system.
Transoral diode laser-assisted resection of a tongue base schwannoma.

Riphah International University, Islamabad, Pakistan.
Schwannomas are benign peripheral nerve sheath tumours with a low risk of malignant transformation. About 25%-40% are in the head and neck region with the posterior third of the tongue being a rather rare site of its growth, and a lesion at this site is understandably difficult to approach and treat. Being benign and encapsulated, surgical excision is in the mainstay of treatment.
