Abstract：
BACKGROUND: Hypertrophic osteoarthropathy (HOA) is a rare and intricate hereditary disease. The appearance and functional deformity of the forehead caused by thickened folds are the main clinical manifestations of patients with hypertrophic osteoarthropathy. The cause of this disease is still unknown. Currently, surgical treatment has become one of the best strategies, mainly for improving the appearance of the forehead. There has been no literature report on the use of \"W\"-shaped skin flap resection for thickened forehead skin in patients with hypertrophic osteoarthropathy.
METHODS: All cases of hypertrophic osteoarthropathy in our department in the last 7 years, and previous literature on hypertrophic osteoarthropathy, were reviewed.
RESULTS: A total of 5 cases of hypertrophic osteoarthropathy in our department (mean age 21 years, all male patients) were reviewed. All patients underwent open surgery to remove the thickened skin on the forehead or the wrinkles and gyrus-shaped scalp. The jagged skin tissue was removed (8-9) cm × (1-2.5) cm × 0.5 cm. The folds and thickness of the frontal skin of the patients were greatly improved after the operation. Patient satisfaction with the treatment outcomes was unanimous. However, one case experienced a postoperative wound infection during follow-up. The utilization of the \"W\"-shaped excision technique allowed for the maximal removal of excessively diseased tissue, thereby facilitating a smoother resolution of the depression.
CONCLUSIONS: A total of 5 cases of hypertrophic osteoarthropathy were treated in our department, and all of them underwent frontal skin \"W\"-shaped excision, which was safe, feasible, and practical, and the postoperative results were satisfactory.

摘要：
背景：肥厚性骨关节病（HOA）是一种罕见且复杂的遗传性疾病。皱褶增厚引起的前额的外观和功能畸形是肥大性骨关节病患者的主要临床表现。这种疾病的原因仍然未知。目前,手术治疗已成为最佳策略之一,主要用于改善前额的外观。尚无文献报道在肥厚性骨关节病患者中使用“W”形皮瓣切除术治疗额头皮肤增厚。
方法：过去7年我科所有肥大性骨关节病病例，和以前关于肥厚性骨关节病的文献，被审查了。
结果：我科共有5例肥大性骨关节病（平均年龄21岁，所有男性患者)进行审查。所有患者都接受了开放手术，以去除额头或皱纹和回形头皮上增厚的皮肤。取锯齿状皮肤组织(8-9)cm×(1-2.5)cm×0.5cm。术后患者额叶皮肤的皱褶和厚度均有较年夜改良。患者对治疗结果的满意度是一致的。然而,1例患者在随访期间出现术后伤口感染。使用“W”形切除技术可以最大程度地去除过多的患病组织，从而促进更平滑的抑郁症的解决。
结论：我科治疗肥大性骨关节病5例，他们都接受了额叶皮肤“W”形切除术，这是安全的，可行,实用，术后效果满意。
