Surgical resection of mandible owing to benign, malignant neoplasm, osteoradionecrosis is common. The resection can be total or segmental depending on the lesion. Loss of mandibular continuity causes deviation of remaining mandibular segment towards the resected side and rotation inferiorly due to muscle pull and scar contracture affecting mastication and esthetics. Surgical reconstruction may not be always possible. Prosthetic rehabilitation plays a major role in these patients. This case series describes different types of guiding flange (GF) prosthesis with modifications for three hemimandibulectomy patients at different time interval after surgery. The article details GF prosthesis combined with physiotherapy to correct deviation of mandible thereby improving mastication, esthetics and speech and thus enhancing the quality of life.
由于良性、恶性肿瘤、放射性骨坏死而进行下颌骨手术切除很常见。根据病变情况,切除可以是全切除或节段性切除。下颌骨连续性的丧失会导致剩余下颌骨段因肌肉牵拉和瘢痕挛缩而向切除侧偏斜并向下旋转,从而影响咀嚼和美观。手术重建并非总是可行。假体修复在这些患者中起着主要作用。本病例系列描述了针对三名半侧下颌骨切除患者在术后不同时间间隔进行改良的不同类型的引导凸缘(GF)假体。本文详细介绍了GF假体结合物理治疗以纠正下颌骨偏斜,从而改善咀嚼、美观和言语功能,进而提高生活质量。
