■本研究的目的是评估上颌肿瘤切除的可及性,切除边缘状态,上颌骨旁正中切开术通过唇裂进行上颌骨切除术后的发病率。
■回顾性分析了2008年至2016年期间,通过唇裂下颌骨切开术和舌骨上颈淋巴结清扫术治疗上颌骨肿瘤的20例连续患者进行了上颌骨切除术和原发性肿瘤切除术。患者详细信息,包括肿瘤部位,延伸和颈淋巴结受累。被记录下来。切除技术,还讨论了手术切除的切缘状况。从患者随访记录中获得疾病状态。根据感染评估下颌骨切开术部位的发病率,截骨愈合,神经紊乱和张嘴。机构研究委员会批准了这项研究。
■所有患者都接受了充分的肿瘤整块切除,除了2例上缘阳性的患者.除一名患者在放疗后截骨部位感染外,所有患者的截骨部位均愈合良好。在四名患者中遇到了最小的神经发病率(三名患者有舌神经假设,两名患者有下牙槽神经假设),在所有四名患者中都恢复了。术后6个月。术后切口间距离令人满意,平均为30.5mm。
■唇裂下颌骨切开术被认为是进入上颌骨及其邻近结构肿瘤的理想方法,SOHND具有III级间隙。这种方法为可手术上颌肿瘤的整块切除提供了极好的可及性,从而产生良好的疤痕和最低的发病率。
UNASSIGNED: The objective of this study was to assess the accessibility in the resection of maxillary tumours, resection margin status, and morbidity following maxillectomy through lip split with paramedian
mandibulotomy approach.
UNASSIGNED: A retrospective
review of 20 consecutive patients who underwent maxillectomy with resection of primary tumours through lip split
mandibulotomy approach with supraomohyoid neck dissection for maxillary tumours between 2008 and 2016. Patients details including the tumours site, extension and neck node involvement. were recorded. Resection technique, status of surgical resected margins was also discussed. Disease status was obtained from patients follow up records. Morbidity was assessed at
mandibulotomy site in terms of infection, osteotomy healing, neural disturbance and mouth opening. The institutional research committee approval was taken for this study.
UNASSIGNED: All patients underwent adequate en bloc resection of the tumours, except in two patients in whom superior margins was positive. Osteotomy site healed well in our all patients except in one patient in whom there was infection at the osteotomy site during post radiation therapy. Minimal neural morbidity was encountered in four patients (three patients had lingual nerve hypothesia and two patients had inferior alveolar nerve hypothesia) which recovered in all four patients, over the 6th month post-operative period. Post-operative interincisal distance was satisfactory with a mean of 30.5 mm.
UNASSIGNED: Mandibulotomy with lip split is considered to be an ideal approach to access tumours of maxilla and its adjacent structures, SOHND with level III clearance. This approach provide excellent accessibility for en bloc resection of operable maxillary tumours with good outcome of resultant scar and minimal morbidity.
