%X <B>OBJECTIVE: </B>To investigate the clinical efficacy of a modified paramedian lower lip-submandibular approach for maxillary (subtotal) total resection.<BR><B>METHODS: </B>Eleven patients of maxillary tumors underwent maxillary (subtotal) total resection through the modified paramedian lower lip-submandibular approach. Clinical follow-up visits were conducted to evaluate appearance restoration, facial nerve functional status, parotid gland functional status, and orbital region complication.<BR><B>RESULTS: </B>During the follow-up period of 6-36 months, the appearance of all 11 patients recovered well. All cases presented hidden scars. No facial nerve and parotid duct injury, lower eyelid edema, lower eyelid ectropion, or epiphora in all cases was observed.<BR><B>CONCLUSIONS: </B>Applying modified paramedian lower lip-submandibular approach to maxillary (subtotal) total resection effectively reduces incidence of orbital region complications including lower eyelid edema, lower eyelid ectropion, and epiphora, which often occur to traditional approach. The modified approach produces more subtle scars than other methods and should be applied to treatment of maxillary (subtotal) total resection.<BR>目的 探讨一种新的改良下唇旁正中-颌下入路在上颌骨（次）全切除术中的应用价值。方法 对11例上颌骨肿瘤患者采用改良下唇旁正中-颌下入路进行上颌骨（次）全切除术。术后对患者面形恢复、面神经及腮腺功能状态、眶区并发症等进行分析。结果 随访6~36个月，所有患者面形恢复良好，切口瘢痕隐蔽，均无面神经、腮腺导管损伤症状，也无下睑水肿、睑外翻、溢泪等眶区并发症。结论 改良下唇旁正中-颌下入路行上颌骨（次）全切除术可有效降低下睑水肿、睑外翻、溢泪等眶区并发症的发生率，且切口瘢痕隐蔽，未增加其他并发症的发生，值得临床推广。.
