復發顎骨外生骨贅－病例報告

骨疣和外生骨贅皆自顎骨區皮質骨所長出的結節狀骨質突起，常見於顎骨區，主要依照解剖位置和型態作區分。骨疣可能和基因及環境等諸多因素交互影響有關。外生骨贅則可能是一種顎骨對過度或異常的咬合壓力因應而生的額外骨質。發生率依研究統計不同可從5%至60%，具男性傾向。此二類多生骨通常無症狀，患者常因外傷導致反覆性潰瘍及疼痛和補綴物的佩戴需要而求助手術切除。本文提出一經手術切除後再度復發的顎骨外生骨贅之案例報告，此位39歲男性患者於25歲時曾接受手術切除上顎骨疣和上下顎齒槽骨外生骨贅，30歲時回診主訴原本經手術切除後的顎骨外生骨贅有再度生長的情形，臨床檢查發現證實所述39歲再次接受上下顎齒槽骨外生骨贅切除手術，病理檢查確認為贅生骨。目前門診追蹤一年餘並無腫瘤復發之跡象。一般來說，外生骨贅在手術切除後預後良好。由於此例出現罕見復發之特殊情形，遂提出案例報告並針對比例骨疣和外生骨贅共存的現象做相關討論。

Torus and exostosis are local bony protuberances that arise from the cortical plate. These benign growths frequently affect the jaws and vary in different locations and morphologies. Development of the torus is multifactorial, including both genetic and environmental influences. The etiology of exostosis has been suggested that the bony outgrowth represents a reaction to increased or abnormal occlusal stress in the involved areas. The prevalence ranges from 5% to 60% with male predilection. Sometimes these lesions are surgically removed if repeatedly exposed to trauma, which can in turn cause painful ulcers, or for the requirement of dental prosthesis. Recurrence, though, is very rare.This report presented a rare case of recurrent jaw bone exostoses. This 39 year old Taiwanese patient received his first surgical removal of upper torus and exostoses at an age of 25. He returned at thirty again, complaining of a gradual regrowth of jaw bone mass, which was clinically confirmed. He underwent a second surgery at thirty-nine, and the pathology report confirmed the diagnosis. No recurrence was noted after one year follow-up.Generally, the prognosis of jaw bone exostoses after surgical excision is good. Since it is a rare recurrence, we propose the case for detailed medical treatment and discussion.
