Abstrakt: Introduction: Schwannomas are rare benign neurogenic tumours. About 25-45% of extracranial schwannomas are found in the head and neck region. In the head and neck, they can arise from various cranial, peripheral and autonomic nerves. Due to this, they have varied clinical presentations.
Material and Methods: This retrospective cohort includes 97 patients diagnosed with extra cranial head and neck schwannoma, and operated in the Otolaryngology and Head & Neck Surgery department, from 2013 to 2022. The parameters observed were the age and gender distribution, location, nerve of origin, size, pressure symptoms, cranial palsies, post-operative symptoms, recurrence and complications. The data were collected from the institute's electronic records.
Results: The median age of the study population was 36 years; among them, 51 were men and 46 were women. The most common tumour location was parapharynx. The patients had varied head and neck symptoms, of which 23.7% had nerve paresis at presentation. Transcervical surgical approaches was most used. New onset cranial nerve paresis immediately post-surgery was noted in 22.7%. Recurrence was noted in 2% of cases.
Conclusions: Extra cranial schwannomas are uncommon neoplasms and have varied presentations. Comprehensive evaluation with appropriate imaging should be done in all cases. Though benign, patients can present with nerve paresis. Recurrence is uncommon after complete resection.
