在Conley(1979)和Allen等(1981)报告的唇下手术途径基础上,我们简化了其操作步骤,能够充分暴露鼻腔、上颌窦及鼻咽部。7例手术效果满意。我们认为这种途径有一定的临床实用价值,故报告如下: 手术方法:唇龈切口,外侧起至上颌结节,向内超越中线至第Ⅲ齿,必要时可延长至上颌结节。切开骨膜向上游离患侧面部软组织至眶下孔。沿梨状孔切 Based on the subpleural approach reported by Conley (1979) and Allen et al. (1981), we simplified the procedure to fully expose the nasal cavity, maxillary sinus, and nasopharynx. Satisfactory results in 7 cases. We think this approach has some clinical practical value, so the report is as follows: Surgical methods: lip gingival incision, lateral to the maxillary nodules, inward beyond the midline to the third tooth, if necessary, can be extended to the maxillary nodules. Cut off the periosteum upward from the affected side of the soft tissue to the infraorbital foramen. Cut along the pear-shaped hole
