作者复习了大约700例腮腺切除术病例,其中收集了98例腮腺间隙非涎腺源性肿瘤,占全部腮腺手术病例的14%。腮腺间隙的解剖范围:后界为外耳道及乳突尖,上界为颧弓,前界为下颌枝及嚼肌,下方为腮腺下极。腮腺间隙内的肿瘤常常被诊断为涎腺肿瘤,只有在少数情况下术前能获得正确诊断,然而在大多数情况下非涎腺性肿瘤只能在手 The authors reviewed approximately 700 parotidectomy cases, in which 98 cases of parotid gland non-sacral gland-derived tumors were collected, accounting for 14% of all parotid gland surgery cases. The anatomical range of the parotid gland gap: the posterior border is the external auditory meatus and the mastoid tip, the upper border is the zygomatic arch, the anterior border is the mandibular branch and the chewing muscle, and the lower part is the parotid gland. Parotid gland tumors are often diagnosed as parotid gland tumors. Only in rare cases can correct diagnosis be obtained before surgery. However, in most cases, non-parotid gland tumors can only be found in the hand.
