摘要
外耳道胆脂瘤发病率点耳科疾病的0．1％，病因多样，多与炎症及刺激有关，主要是由于外耳道内段及鼓膜外侧表皮过度增生，角化，脱落，堆积在外耳道而成的，治疗上以清除病变，预防复发为主。治疗方法上，清除病变后，行外耳道成形术、乳突根治或乳突改良根治术。本文认为，术前颞骨CT对于外耳道胆脂瘤的治疗方案的制定比较重要，术前应该仔细阅读CT，重点观察外耳道骨壁的破坏情况，如果外耳道皮质骨完整，即I期，可选择经耳道胆脂瘤清除术，如果外耳道骨质破坏明显，但乳突以及鼓室未受累，或乳突仅几个气房受累，即Ⅱ期，可以选择经耳后入路的外耳道胆脂瘤清除术，同时用乳突骨粉填充外耳道凹陷处，以及裸露乳突气房。如果CT显示，乳突和鼓室明显累及，应该进行鼓室成型术。
External auditory meatus cholesteatoma disease incidence rate ear department disease 0.1%, the cause of disease is di- verse, many with inflammation and stimulation related, mainly is because in the external auditory meatus the section and the tympanic membrane flank epidermis proliferation,the keratinization, falls off excessively, piles up in,the treatment which the external auditory meatus becomes eliminates the pathological change, the prevention recrudescence primarily. In the method of treatment, after eliminates the pathological change, good external auditory meatus forming technique, mastoid process permanent control or mastoid process improvement root governing skill. This article believed that,in front of the technique nie bone CT quite is important regard- ing the external auditory meatus cholesteatoma treatment plan formulation,in front of the technique should read CT carefully,abservation of primary mass data external auditory meatus bone wall destruction situation, if external auditory meatus cerebral cortex bone integrity, namely I The time, may choose after the meatus auditorius cholesteatoma elimination technique,if the external auditory meatus ossein destruction is obvious, but the mastoid process as well as the drum room has not exhausted oneself, or mastoid process only several air compartments exhaust oneself,namely Ⅱ The time, may choose after the ear the admission passage external auditory meatus cholesteatoma elimination technique,simultaneously uses the mastoid process bonedust to fill the external auditory meatus hollowly place,as well as exposed mastoid process air compartment. If CT demonstrated, the mastoid process and the drum room implicates obviously, should carry on the drum room formation technique.
