Here the authors present the surgical management of a 78-year-old female with a superficial squamous cell carcinoma of the mucosa overlying her edentulous mandibular alveolus with no evidence of bony invasion.Combining the superficial nature of the lesion, patient age and substantial medical comorbidities, a limited intra-oral resection was planned, to avoid the need for free flap reconstruction. The operation required a wide local excision with clear clinical margins and a mandibular rim resection.All of the currently available reconstructions would result in prolonged surgical time, donor site morbidity, and possible secondary procedures. To overcome these pitfalls, a sublingual gland and mylohyoid muscle advancement flap was designed and executed. By combining the mylohyoid muscle and sublingual gland tissue as an advancement flap in a tension-free manner, secured to the remaining circumferential mucosa, a watertight closure was achieved.After an uneventful recovery without complication the patient was discharged the following day. Complete epithelialization was observed on day 25. Adjuvant radiotherapy was offered to reduce the risk of recurrence and progression. To date, no bony exposure and no pathological fractures have occurred.In conclusion, the entire procedure is simple and innovative. There is minimal donor site morbidity, with an immediate return to oral diet and tolerable surgical risks. It requires a small amount of surgical time compared to other reconstructive options and an overall reduced inpatient stay.
本文作者介绍了一例 78 岁女性患者的口腔黏膜表面鳞状细胞癌的手术治疗方法,该患者的无牙下颌牙槽突黏膜受累,但无骨侵犯的证据。考虑到病变的表浅性、患者年龄和大量的合并症,计划进行局限性口腔内切除术,以避免游离皮瓣重建的需要。手术需要广泛的局部切除,有明确的临床切缘,并进行下颌骨缘切除。所有现有的重建方法都会导致手术时间延长、供区并发症和可能的二次手术。为了克服这些困难,设计并实施了舌下腺和颏舌肌推进瓣。通过以无张力的方式将颏舌肌和舌下腺组织组合成推进瓣,并固定在剩余的环状黏膜上,实现了水密性闭合。患者无并发症顺利恢复,次日出院。第 25 天观察到完全上皮化。为降低复发和进展的风险,建议行辅助放疗。迄今为止,未发生骨暴露和病理性骨折。总之,整个手术过程简单且具有创新性。供区并发症轻微,可立即恢复口腔饮食,手术风险可耐受。与其他重建方法相比,手术时间较短,总住院时间也较短。
