目的探讨乳腔镜手术治疗男性乳腺发育症的手术方法和安全性问题。 方法对我院自2010年2月至2011年3月期间收治的11例男性乳腺发育症患者用乳腔镜行单纯皮下腺体切除术。 结果11例手术均获成功，术后3～6 d拔除引流管，术后平均住院时间12.5 d； 术后发生皮下气肿3例，乳头部浅层缺血3例，无其他并发症。 结论乳腔镜手术治疗男性乳腺发育症能达到常规手术无法取得的美容效果，且较为安全。乳腔镜应用前景广阔。
Objective To explore the clinical characteristics and treatment of “kissing fracture” of humeroradial joint. Methods A clinical data of 12 patients with “kissing fracture” of the humeroradial joint between January 2016 and June 2021 was retrospectively analyzed. There were 8 males and 4 females with an average age of 41.9 years (range, 15-75 years). The fractures caused by falling in 7 cases, by falling from height in 3 cases, and by sports in 2 cases. The time from injury to admission was 2-72 hours (median, 2 hours). According to Mason’s classification, the radial head fractures were rated as type Ⅰ in 2 cases, type Ⅱ in 8 cases, and type Ⅲ in 2 cases. According to Grantham’s classification, the humeral capitulum fractures were rated as type Ⅰ in 10 cases and type Ⅱ in 2 cases. Among them, 4 cases of Grantham type Ⅰ humeral capitulum fracture were missed by X-ray film and confirmed by CT and/or MRI. Four cases were complicated with other injuries of elbow joint. The radial head fractures were fixed with screws or mini plate in 11 cases and treated conservatively in 1 case; the humeral capitulum fractures were fixed with screw or plate in 9 cases, removed in 1 case, and treated conservatively in 2 cases. X-ray film was used to evaluate the fracture healing; Mayo Elbow Performance Score (MEPS) was used to evaluate the functional recovery of the affected limb, and the range of motion (ROM) of the elbow joint of the affected limb was detected. Results All the incisions healed by first intention without early complications. All patients were followed up 10-24 months, with an average of 15.2 months. X-ray films showed that all fractures healed, and the healing time was 2-3 months, with an average of 2.3 months. At last follow-up, the ROM of flexion-extension of the elbow joint was 65°-161°, with an average of 136.9°; the ROM of rotation was 70°-180°, with an average of 149.2°. MEPS ranged from 70 to 100, with an average of 87.4; 8 cases were excellent, 2 cases were good, and 2 cases were fair; the excellent and good rate was 83.3%. Conclusion The “kissing fracture” of the humeroradial joint is relatively rare, and the humeral capitulum fracture is milder than radial head fracture. X-ray examination alone can easily miss the diagnosis of Grantham type Ⅰ humeral capitulum fracture. The “kissing fracture” of the humeroradial joint is treated according to the principle of intra-articular fracture, and the good effectiveness can obtain.
