To assess whether locking-screw titanium plates (UniLOCK) and pedicled pectoralis major myocutaneous flaps are a valid alternative to complex reconstruction with bony free flaps in poor prognosis or poor performance status oncological patients with mandibular defects, a retrospective evaluation has been made of outcomes in 27 consecutive cases. No patient died perioperatively. Mean operating time was 270 minutes. Post-operative course was uneventful in 14. Mean follow-up was 13 months with no loss to follow-up. Twelve patients are alive and well, 12 died from their malignancy, two from non-neoplastic causes, and one from second cancer. Plate exposure - the main problem with bridging plates - occurred in 6 (22%, 4 early, 2 late), 4 with symphyseal and 2 with postero-lateral defects: removal was necessary in 2; 2 died with the plate exposed, and 2 had successful re-coverage, increasing the final success rate from 78% to 85%. Most patients considered the aesthetic outcome acceptable, however all edentulous patients complained of unsatisfactory dental rehabilitation. From the acceptable success rate, it may be concluded that bridging plates represent a useful reconstruction method, provided they are well covered by viable muscular tissue. They should be offered to patients contraindicated for more invasive procedures or with limited functional needs, or poor prognosis.
为评估锁定螺钉钛板(UniLOCK)和带蒂胸大肌肌皮瓣是否可有效替代游离骨瓣复杂重建术,用于治疗预后不良或身体状况较差的下颌骨缺损肿瘤患者,我们对连续27例患者的治疗结果进行了回顾性评估。围手术期无患者死亡。平均手术时间为270分钟。14例患者术后过程顺利。平均随访13个月,无失访情况。12例患者存活且状况良好,12例死于恶性肿瘤,2例死于非肿瘤性原因,1例死于二次癌症。钢板外露是桥接钢板的主要问题,6例(22%,4例早期,2例晚期)出现钢板外露,4例为正中联合缺损,2例为后外侧缺损:2例需要取出钢板;2例患者钢板外露时死亡,2例成功再次覆盖,最终成功率从78%提高到85%。大多数患者认为美学效果可接受,然而所有无牙患者均抱怨牙齿修复效果不满意。从可接受的成功率来看,可以得出结论,只要桥接钢板被有活力的肌肉组织良好覆盖,它就是一种有用的重建方法。对于禁忌进行更具侵入性手术或功能需求有限、预后不良的患者,应提供这种方法。
