The medical charts of 267 patients who had primary high-superficial musculoaponeurotic system (SMAS) rhytidectomies were reviewed. The depth of the nasolabial fold was used as an indicator of the degree of descent of the subcutaneous cheek mass, as a guide in procedure selection, and as a method of judging the operative results. Fold depth was assigned a score of 0 to 3, with 3 being most severe. According to their preoperative fold depth, patients were operated on using one of three variants of the high-SMAS technique: sub-SMAS dissection up to the nasolabial fold, sub-SMAS dissection up to the nasolabial fold plus transnasal SMAS graft, or sub-SMAS dissection across the nasolabial fold. An independent trained observer rated the postoperative fold depth in each case from photographs taken at the 6-month follow-up visit. Of patients with fold scores of 2 or 3, 97 percent (183 of 189 patients) showed visible improvement in nasolabial crease depth after the operation.
回顾了267例行原发性高位表浅肌肉腱膜系统（SMAS）除皱术患者的病历。鼻唇沟深度被用作皮下颊部组织下垂程度的指标，作为手术选择的指导，并作为判断手术效果的方法。褶皱深度评分为0至3分，3分为最严重。根据术前褶皱深度，患者采用以下三种高位SMAS技术变体之一进行手术：在鼻唇沟处进行SMAS下分离、在鼻唇沟处进行SMAS下分离并加经鼻SMAS移植、或跨过鼻唇沟进行SMAS下分离。一名独立的训练有素的观察者根据6个月随访时拍摄的照片对每个病例的术后褶皱深度进行评分。在褶皱评分为2或3分的患者中，97%（189例患者中的183例）术后鼻唇沟深度有明显改善。
