应用原位采集的游离龈移植治疗裂隙性龈瘤：病例系列及文献综述

文献信息

中文摘要

裂隙性龈瘤（EF）是一种由慢性义齿刺激引起的口腔前庭反应性纤维增生。我们描述了两例患者（年龄分别为58岁和42岁），其中EF被切除，并使用从切除病变本身采集的游离龈移植（FGG）进行了前庭成形术。在病例1中，切除了上颌前牙区牙槽黏膜的增生皱襞，切口根向复位，并将变薄、去上皮化的移植物固定于骨膜上。在病例2中，切除了种植体周围增生组织，并使用手风琴技术制备的移植物放置在愈合基台周围。病例1随访2个月和10个月，病例2随访2个月；两例愈合均顺利，每次随访时均可见临床足够的角化黏膜带和稳定的前庭深度。在短随访两例报告的限制下，使用病变本身作为移植物来源提供了可接受的角化黏膜和前庭深度。有必要进行更大规模的前瞻性研究，随访12-24个月。

英文摘要

Epulis fissuratum (EF) is a reactive fibrous overgrowth in the oral vestibule caused by chronic denture irritation. We describe two patients (aged 58 and 42 years) in whom EF was excised and vestibuloplasty performed using a free gingival graft (FGG) harvested from the excised lesion itself. In Case 1, a hyperplastic fold of the maxillary anterior alveolar mucosa was removed, the incision apically repositioned, and the thinned, deepithelialized graft immobilized over the periosteum. In Case 2, peri-implant hyperplastic tissue was excised and the graft, prepared using the accordion technique, was positioned around the healing abutments. Case 1 was followed up at 2 and 10 months and Case 2 at 2 months; healing was uneventful in both, with a clinically adequate band of keratinized mucosa and stable vestibular depth at each visit. Within the limitations of this short-follow-up two-case report, using the lesion itself as the graft source provided acceptable keratinized mucosa and vestibular depth. Larger prospective studies with 12-24-month follow-up are warranted.
