Eighteen consecutive patients underwent a lateral temporal bone resection for the treatment of tumors originating in the auricle, the external auditory canal, the periauricular skin, or the parotid and were retrospectively analyzed. The different lateral temporal bone resections performed have been categorized into four types. The type I resection consists of the removal of the tympanic bone and the external auditory canal lateral to the tympanic membrane. The type II resection consists of the removal of the entire tympanic bone, the tympanic membrane, the incus, and the malleus, preserving the facial nerve and the inner ear. Type III resections remove, in addition to the those structures removed in type II resections, the distal facial nerve and fallopian canal, the mastoid tip, the styloid process, and the stylomastoid foramen. The type IV resection consists of the removal of only the mastoid tip and the inferior portion of the tympanic bone. When the techniques of lateral temporal bone resection are used appropriately, adequate surgical treatment of patients with selected advanced and recurrent malignant tumors of the external ear, the periauricular skin, and the parotid is possible with low morbidity and a high probability of local regional control.
连续18例患者接受了颞骨外侧切除术，以治疗起源于耳廓、外耳道、耳周皮肤或腮腺的肿瘤，并进行了回顾性分析。所施行的不同颞骨外侧切除术已分为四种类型。I型切除术包括切除鼓骨和鼓膜外侧的外耳道。II型切除术包括切除整个鼓骨、鼓膜、砧骨和锤骨，保留面神经和内耳。III型切除术除了切除II型切除术中的那些结构外，还切除面神经远端和面神经管、乳突尖、茎突和茎乳孔。IV型切除术仅包括切除乳突尖和鼓骨的下部。当适当使用颞骨外侧切除术技术时，对于选定的晚期和复发性外耳道、耳周皮肤及腮腺恶性肿瘤患者，有可能进行充分的手术治疗，且发病率低，局部区域控制的可能性高。
