BACKGROUND
There have been few cases reported of exostoses following a free gingival graft. In 1980, a free gingival graft was placed on the facial level of 33-34, developing over the years a significant enlargement. In 1999, since the patient felt progressively uncomfortable with the enlarged area, its surgical reduction was proposed.
METHOD
Under local anesthesia, the hard tissue developed under the previously-grafted area, was significantly reduced. The specimen, together with a fragment of the covering soft tissue, was sent for histological analysis.
RESULTS
The surgical wound healed uneventfully, and the patient was satisfied with the results. The histology showed the presence of mature bone surrounded by a dense connective tissue, whereas the gingival tissue showed acanthosis and fibrosis.
CONCLUSION
The development of exostoses following a free gingival graft can be considered an unpredictable, albeit infrequent side-effect of this procedure. The fact that most of these exostoses appear in the cuspid-premolar area, deserves further consideration.
背景
关于游离龈瓣移植术后出现外生骨疣的病例报道较少。1980年，在33 - 34牙面部进行了游离龈瓣移植，多年来该区域显著增大。1999年，由于患者对增大区域逐渐感到不适，建议进行手术缩小。
方法
在局部麻醉下，对先前移植区域下方形成的硬组织进行了显著缩小。将标本连同覆盖软组织的碎片送去做组织学分析。
结果
手术创口顺利愈合，患者对结果满意。组织学显示存在被致密结缔组织包围的成熟骨，而牙龈组织显示棘皮症和纤维化。
结论
游离龈瓣移植术后外生骨疣的发生可被视为该手术一种不可预测但不常见的副作用。这些外生骨疣大多出现在尖牙 - 前磨牙区域这一事实值得进一步研究。
