To review retrospectively the benefits of using mandibulotomy as an access for tumors involving the maxilla and infratemporal fossa.
Twenty-four consecutive patients with tumors involving the maxilla and infratemporal fossa underwent maxillectomy through mandibular access osteotomy. Patient details and postoperative follow-up were reviewed and recorded. Postoperative complications such as neural morbidity and problems relevant to the procedure were evaluated. Ethical clearance from the medical practices board of the hospital was not required for this study.
All but 1 patient underwent en bloc resection of the maxillary tumor with a histologically negative margin. One patient with adenoid cystic carcinoma had a positive orbital margin. Residual mouth opening smaller than 2.5 cm was observed in 4 patients. Healing of the osteotomy site was satisfactory in 21 patients. Three patients had osteotomy-related complications that required secondary intervention. Neural morbidity was temporary and cosmetic outcome of the procedure was excellent.
Mandibular access osteotomy is an acceptable approach to tumors involving the maxilla and infratemporal fossa. The advantages of wide exposure, minimal morbidity, and good cosmesis make it superior to the conventional panfacial approach. This article highlights the advantages of this procedure and discusses conventional approaches with review of the literature.
回顾性分析采用下颌骨切开术作为涉及上颌骨和颞下窝肿瘤的手术入路的益处。
24例连续的涉及上颌骨和颞下窝肿瘤的患者通过下颌骨入路截骨术接受了上颌骨切除术。回顾并记录患者的详细信息及术后随访情况。评估术后并发症,如神经损伤及与手术相关的问题。本研究无需获得医院医疗实践委员会的伦理批准。
除1例患者外,所有患者均接受了上颌骨肿瘤的整块切除,组织学切缘阴性。1例腺样囊性癌患者眶缘切缘阳性。4例患者术后开口度小于2.5 cm。21例患者截骨部位愈合良好。3例患者出现与截骨相关的并发症,需要二次干预。神经损伤为暂时性,手术的美容效果良好。
下颌骨入路截骨术是治疗涉及上颌骨和颞下窝肿瘤的一种可接受的方法。广泛暴露、发病率低和美容效果好等优点使其优于传统的全颜面入路。本文强调了该手术方法的优点,并结合文献回顾讨论了传统手术方法。
