Near-total mandibular reconstruction poses many challenges to reconstructive surgeons. The purpose of this article is to present a challenging case in a patient with osteoradionecrosis of the mandible requiring a near-total mandibular reconstruction using bilateral scapula tip free tissue reconstruction. A 68-year-old African-American male with a history of T2N0M0 squamous cell carcinoma of the tonsil presented with advanced stage osteoradionecrosis of the mandible. Reconstruction was planned using 3D Systems (Denver, CO), mandibular osteotomies were planned inferior to the sigmoid notch on the ascending rami. Neither fibula flap was amenable for harvesting due to poor vasculature of the patient's lower extremities, and bilateral scapula tip free flaps were subsequently planned. The post-operative course was complicated by venous congestion in the right scapula flap which required revision to the venous anastomosis on POD 1. The patient had intraoral breakdown that required debridement in the operating room and application of a cellular matrix. The patient fully recovered from the acute surgery and was discharged home without a tracheostomy. At the last follow up visit, the patient was taking 100% of diet peroral and had no signs of oral incompetence, mental projection was satisfactory, and the ability to verbally communicate was unimpaired. We report a complex case of near-total mandibular reconstruction using simultaneous bilateral scapula tip free flaps. While we do not advocate simultaneous bilateral scapula tip free flaps as the standard of care for large mandibulectomy defects, it may be considered for patients in which traditional osseous free flaps are not available.
下颌骨近全切除重建对重建外科医生来说带来了许多挑战。本文的目的是报道一例具有挑战性的病例,该患者为下颌骨放射性骨坏死,需要使用双侧肩胛骨尖游离组织重建进行近全下颌骨重建。一位 68 岁的非裔美国男性,患有扁桃体 T2N0M0 鳞状细胞癌,患有晚期下颌骨放射性骨坏死。计划使用 3D 系统(科罗拉多州丹佛市)进行重建,在下颌骨升支的乙状切迹下方进行下颌骨切开术。由于患者下肢血管状况不佳,无法进行腓骨皮瓣移植,随后计划进行双侧肩胛骨尖游离皮瓣移植。术后过程中,右侧肩胛骨皮瓣出现静脉淤血,需要在术后第 1 天对静脉吻合口进行修正。患者出现口腔内崩裂,需要在手术室进行清创,并应用细胞基质。患者从急性手术中完全康复,无需行气管造口术即可出院。在最后一次随访时,患者经口摄入 100%的饮食,无口腔功能不全的迹象,精神投射满意,言语交流能力无障碍。我们报告了一例使用双侧肩胛骨尖游离皮瓣同时进行复杂近全下颌骨重建的病例。虽然我们不主张将双侧肩胛骨尖游离皮瓣同时作为大型下颌骨切除术缺损的标准治疗方法,但对于无法进行传统骨游离皮瓣的患者,可以考虑使用该方法。
