颞骨胆固醇囊肿,通常称为颞骨胆固醇肉芽肿(TCG),最早于1894年由Manasse氏描述。其本质上与胆脂瘤有明显的差异。作者对已经手术的TCG患者进行回顾分析,并对其诊断与治疗有关问题进行探讨。经手术证实TCG的患者14例(男3例,女11例)平均年龄36.8岁;病变在岩尖部位9例,中耳(或中耳+乳突)部位5例。临床症状以听力减退为主,发生在中耳部位者多为传音性聋岩尖部位者听力可为正常或为混合性聋和感音神经性聋(本文岩尖部有6/9例属感音神经性聋),次为耳鸣、平衡失调等症状。由于TCG的病理主要为颞骨气房被阻塞,因引流不畅和通气障碍而形
Temporal bone cyst, commonly known as temporal bone cholesterol granuloma (TCG), was first described by Manasse in 1894. It is essentially different from cholesteatoma. The author of the TCG patients have been analyzed retrospectively, and its diagnosis and treatment-related issues to be explored. 14 cases (3 males and 11 females) of TCG were confirmed by operation. The average age was 36.8 years old. There were 9 cases in the petrous apex and 5 cases in the middle ear (or middle ear and mastoid). The main clinical symptoms of hearing loss, occurred in the middle ear were mostly acuity deaf parts of the tip of the hearing can be normal or mixed deafness and sensorineural deafness (here tip of the rock 6/9 cases Sensorineural deafness), followed by tinnitus, balance disorders and other symptoms. Due to the main pathological TCG of the temporal bone atrial obstruction due to poor drainage and ventilatory disorders
