A New Technique for Use Instead of Lateral Crural Overlay for Reduction of Nasal Tip Projection in Revision Rhinoplasty.

Abstract

Objective: Correction of nasal tip projection (NTP) deformities involve techniques for the lower lateral cartilage of the nose. Previously, it would have been surgically difficult to perform the lateral crural overlay (LCO) technique for the second time in revision rhinoplasty in patients who already had undergone rhinoplasty with the LCO technique because of the length of the NTP. In this study, we evaluated the lateral crural segmental excision (LCSE) technique in patients with overprojected nasal tip in revision rhinoplasty.

Methods: We retrospectively studied the cases of 19 patients who had initially undergone rhinoplasty with the LCO technique for overprojected nasal tip, and later underwent revision rhinoplasty with the LCSE technique after insufficient NTP was observed on facial analysis between 2018 and 2022.

Results: Of the patients, 12 (63%) were male, with an average age of 29.6 years, and 7 (17%) patients were female, with an average age of 25.3 years. Using Goode's formula, NTP indexes of patients measured 79.4±1.8 preoperatively and 56.0±1.3 postoperatively. Stastically significant difference was observed between preoperative and postoperative values. None of the patients had malnutrition at the incision margins, and all patients recovered on time and without any problems. Granulation tissue was detected in the mucosa in only one patient.

Conclusion: The LCSE technique, with a short surgical time, recovery period without complications, and satisfactory nasal respiratory function, is preferred over a second LCO application in cases of NTP.
