神经鞘瘤(Neurilemmoma)或称雪旺氏瘤(Schwannoma),是一种生长缓慢的起源于神经鞘,由雪旺氏细胞和结缔组织组成的肿瘤。咽旁神经鞘瘤可发源于任何周围神经、交感神经或副交感神经。肿瘤呈淡红色、黄色或珠灰色,通常质地坚实,但大的肿瘤有时可发生中心性出血、囊性变或液化坏死。我院摘除的瘤体最大约鹅蛋大,最小如鸽蛋大。自1968年n月到1977年12月九年中共收治咽旁神经鞘瘤患者14例(男5例,女9例)。年龄从18到61岁。从发现肿瘤到就医时间三个月至九年不等。本组病例由于肿瘤侵及的范围或累及的神多可出现以下不同症状和体征。见下表阂一鼻溉培热陈图二摘除的肿瘤(呈囊性变力退视减力降听下 .
Neurlemmmoma, or Schwannoma, is a slow-growing neoplasm that originates from Schwann cells and connective tissue. Parapharyngeal schwannomas can originate from any peripheral, sympathetic or parasympathetic nerve. Tumors are light red, yellow, or beaded gray, usually with a firm texture, but large tumors can sometimes undergo central bleeding, cystic degeneration, or liquefaction and necrosis. Most of the tumors removed in our hospital are about the size of a goose egg, and the smallest is a pigeon egg. From November 1968 to December 1977, the Chinese Communist Party treated 14 patients with parapharyngeal schwannoma (5 males and 9 females). Age from 18 to 61 years old. From three months to nine years from the discovery of tumors to medical treatment. In this group of patients, the following symptoms and signs may occur due to the extent of tumor invasion or the involvement of God. See the following table: 阂 鼻 鼻 溉 溉 溉 溉 热 肿瘤 肿瘤 肿瘤 肿瘤 肿瘤 肿瘤 肿瘤 肿瘤.
