目的探讨内眦动脉为蒂的鼻唇沟皮瓣修复鼻多个亚单位缺损的临床效果。方法对19例鼻亚单位缺损患者均采用内眦动脉为蒂的鼻唇沟皮瓣修复,创面面积为1.1 cm×1.5 cm~2.5 cm×4.0 cm。根据缺损面积,在鼻唇沟处设计包括内眦动脉走行在内的蒂在上方的皮瓣,沿设计线切开至浅筋膜,于肌层掀起皮瓣;在无张力的情况下旋转皮瓣至创面,缝合创口。结果本组共19例患者,术后随访6~24个月,皮瓣全部成活,且全部完成一期修复手术,外形良好,无瘢痕增生。结论采用内眦动脉为蒂的鼻唇沟皮瓣,可以利用面颊部与鼻唇部的天然皱褶,很好地隐藏术后瘢痕,且具有血供丰富的特点,是一种可用于鼻多个亚单位修复的良好方法。
Objective To investigate the clinical effect of nasolabial fold pedicle pedicle pedicle on the repair of multiple nasal subunit defects. Methods Nineteen patients with nasal subunit defects were repaired by the pedicle of the nasolabial fold pedicled with the pedicle of the internal iliac artery. The wound area was 1.1 cm × 1.5 cm ~ 2.5 cm × 4.0 cm. According to the defect area, at the nasolabial fold at the pedicle design, including pedigree artery pedicle flap in the top, along the design line incision to the superficial fascia, flap flap in the muscle layer; under tension without rotating skin Flap to the wound, suture wound. Results A total of 19 patients were followed up for 6-24 months. All the flaps survived, and all the repairs were completed. The appearance was good without scar hyperplasia. Conclusions The nasolabial fold pedicle pedicle with internal 眦 artery can utilize the natural folds of the cheeks and nasolabial folds to hide the postoperative scar very well and has the characteristics of rich blood supply. A good way to fix subunits.
