Based on clinical impressions and subjective reports by patients, it is generally accepted that a loss of mandibular continuity will result in decreased masticatory function while preserving continuity will result in maintenance of masticatory function. Surprisingly, there is a paucity of well controlled studies objectively evaluating masticatory function to support these statements. The purpose of this study was to objectively evaluate masticatory function in a patient who underwent surgical resection for cure of a tonsillar carcinoma where a lateral mandibulotomy was used. Masticatory performance and swallowing threshold were assessed using a 0.5 gm frito as the test food substance and a sieve analysis. The subject was evaluated pre and post surgery and post prosthetic rehabilitation. When compared with pre surgery function, masticatory function and swallowing threshold were maintained and enhanced with prosthetic treatment 1 year post surgery. Maintenance of mandibular continuity did have functional merit for the subject studied.
基于临床印象和患者的主观报告，人们普遍认为下颌连续性丧失会导致咀嚼功能下降，而保持连续性则会维持咀嚼功能。令人惊讶的是，缺乏经过严格控制的客观评估咀嚼功能的研究来支持这些说法。本研究的目的是客观评估一名因扁桃体癌接受手术切除并采用下颌骨外侧切开术的患者的咀嚼功能。使用0.5克炸玉米片作为测试食物，通过筛分分析评估咀嚼性能和吞咽阈值。在手术前、手术后以及假体修复后对受试者进行评估。与术前功能相比，术后1年的假体治疗维持并增强了咀嚼功能和吞咽阈值。对于所研究的受试者，保持下颌连续性确实具有功能上的益处。
