METHODS: Consecutive head and neck oncology cases involving maxillary resections over a 27-year period between January 1994 and November 2020 were identified from hospital records and previous studies. Case note review focussed on clinical characteristics, reconstruction, prosthetic rehabilitation, and survival.
RESULTS: There were 186 patients and the tumour sites were: alveolus for 56% (104), hard palate for 19% (35), maxillary sinus for 18% (34) and nasal for 7% (13). 52% (97) were Brown class 2 defects. Forty-five patients were managed by obturation and 78% (142/183) had free tissue transfer. The main flaps used were radial (52), anterolateral thigh (27), DCIA (22), scapula (13) and fibula (11). There were significant changes over time regarding reconstruction type, use of primary implants, type of dental restoration, and length of hospital stay. Overall survival after 24 months was 64% (SE 4%) and after 60 months was 42% (SE 4%).
CONCLUSIONS: These data reflect a shift in the reconstruction of the maxillary defect afforded by the utilisation of zygomatic implants.
方法:在1994年1月至2020年11月的27年间,从医院记录和以前的研究中发现了涉及上颌骨切除术的连续头颈部肿瘤病例。病例记录回顾集中于临床特征,重建,假肢康复,和生存。
结果:有186例患者,肿瘤部位为:肺泡占56%(104),硬腭占19%(35),上颌窦占18%(34),鼻为7%(13)。52%(97)为棕色2类缺陷。45例患者接受闭塞治疗,78%(142/183)的组织游离转移。使用的主要襟翼是径向的(52),大腿前外侧(27),DCIA(22),肩胛骨(13)和腓骨(11)。随着时间的推移,重建类型发生了重大变化,使用初级植入物,牙齿修复的类型,和住院时间。24个月后的总生存率为64%(SE4%),60个月后的总生存率为42%(SE4%)。
结论:这些数据反映了通过使用zy骨植入物提供的上颌骨缺损重建的转变。
