Pathology of acoustic nerve Schwannoma in vivo and in vitro.

abstract：:Laryngeal paragangliomas are rare submucosal lesions that arise from paraganglion cells located in the false vocal fold and subglottic larynx. To date, 76 recognized cases have been reported in the world literature. Symptoms arise when the lesions become large enough to impair function. Supraglottic paragangliomas cau...
