逆行股前外侧岛状皮瓣修复膝关节周围软组织缺损

【摘要】目的 探讨采用股前外侧逆行岛状穿支皮瓣修复膝关节周围严重创伤性软组织缺损的疗效。方法 回顾性分析2008年至2012年,我院采用股前外侧逆行岛状穿支皮瓣修复膝关节周围严重创伤性皮肤软组织缺8例,术后观察皮瓣存活情况和恢复情况。结果 除了1例病例边缘小部分坏死,通过换药愈合外,其余皮瓣全部存活,皮瓣质地弹性好,外形满意。术后无明显感染及并发症。结论 采用股前外侧逆行岛状穿支皮瓣修复膝关节周围严重创伤性软组织缺损,具有血供可靠,血管蒂较长等优点,术后疗效满意。     

Wide-Awake Primary Flexor Tendon Repair,Tenolysis, and Tendon Transfer

Tendon surgery is unique because it should ensure tendon gliding after surgery. Tendon surgery now can be performed under local anesthesia without tourniquet, by injecting epinephrine mixed with lidocaine, to achieve vasoconstriction in the area of surgery. This method allows the tendon to move actively during surgery to test tendon function intraoperatively and to ensure the tendon is properly repaired before leaving the operating table. I applied this method to primary flexor tendon repair in zone 1 or 2, tenolysis, and tendon transfer, and found this approach makes tendon surgery easier and more reliable. This article describes the method that I have used for tendon surgery.     

Rare case of external dental fistula of the submental region misdiagnosed as inverted follicular keratosis and thyroglossal duct cyst

IntroductionOdontogenic cutaneous sinus tract is a relatively rare occurrence that can be complicated to diagnose. The presence of a cutaneous lesion is often not even partly associated with a dental etiology because of the less frequency of occurrence in the case of dental symptoms. Consequently, the underlying dental cause is often missed leading to inappropriate diagnosis and treatment.Case presentationHere, we report the case of a 45-year-old man who presented with a persistent lesion of the cervical region. At the time of presentation, the lesion had been present for approximately one year with a gradual increase in size but no specific symptoms. The patient had previously undergone punch resection under local anesthesia, which resulted in a histopathological diagnosis of inverted follicular keratosis. A diagnosis was made of an odontogenic cutaneous sinus tract secondary to chronic apical periodontitis of the left mandibular second molar.DiscussionCutaneous sinus tract in the face and neck is most likely to develop intraorally. Root canal treatment or surgical extractions are the common treatment choices. A previously reported review of 137 cases found that 106 (77%) were treated by extraction and 27 (20%) were treated by surgical or conservative nonsurgical endodontic therapy.ConclusionEarly diagnosis of cutaneous sinus tract using proper aid is responsible for shortening the treatment duration and avoiding unnecessary treatment.
