Abstract
A large proportion of schwannomas are found in the head and neck region. Schwannoma located within the larynx however is uncommon. The characteristic features, clinical presentations, treatment and the outcomes of patients with laryngeal schwannoma are therefore not clearly understood. The aim of this comprehensive review is to compile, analyze and present the details to develop a consensus and augment the available literature on laryngeal schwannoma. A comprehensive literature search on laryngeal schwannoma was performed on PUBMED/MEDLINE, EMBASE, CINAHL and Science Citation Index using MeSH words. A total of 55 patients were reviewed in this study. 40.7% of the tumours arose from the aryepiglottic fold or arytenoids. Other areas where tumours were found included the false cord, true vocal cord, epiglottis, subglottis, piriform sinus and the post cricoid area. 64.9% patients presented with dysphonia. Others typically present with multiple symptoms related to the mass effect and location of the tumour. All patients were managed surgically with different techniques and approaches. Majority of patients were alive with no residual disease. There were five recurrences and no mortality to date. Schwannoma within the larynx can present with a variety of symptoms. Surgical excision remained as the treatment of choice with good overall prognosis.
