Objective: Increasing the nasolabial angle with nasal tip rotation in tip surgery in rhinoplasty may cause the lower 1/3 of the face to look longer. In particular, it can be perceived as an increase in upper lip length. The aim of this study is to compare the effects of two types of surgical techniques, that enhance tip rotation, on nasolabial angle; upper lip projection and upper lip length. Material and Methods: Preoperative, early postoperative and late postoperative photographs of 78 patients who underwent rhinoplasty with application of tongue-in-groove or columellar strut maneuvers were examined. The outcome measures were determined as postoperative nasolabial angle, upper lip projection angle and upper lip length, which were calculated in the computer program. Results: Columellar strut was applied in 46 patients (59%), tongue in groove was applied in 32 patients (41%). Nasolabial angle increased significantly in both groups (p=0.01). In the both group, the upper lip length increased significantly (p=0.01). The Z angle was found to be decreased in both columellar strut and tongue-in-groove groups, inversely proportional to the projection (3 and 4.8 degrees, respectively). Conclusion: Both columellar strut and tongue in groove maneuvers are effective in increasing the rotation. With these techniques applied in tip surgery, the length and projection of the upper lip increases. It was found that, for each one degree increment in nasolabial angle, the length of the upper lip increased by 0.03 mm using the columellar strut technique and 0.04 mm using the tongue-in-groove technique.
