Abstract

Lateral crural cut and overlay (LCC) or medial crural cut and overlay (MCC) are two of the many techniques applied to ensure an adequate nasal tip projection and rotation, but little evidence supports their long-term efficacy. Fifty-four rhinoplasty candidates were studied prospectively in this randomised clinical trial. The subjects were randomly divided into two groups according to the use of LCC or MCC. The outcome measures were gaining and maintaining tip projection and rotation in the long term. Standardised photographs taken before and at three and 12 months after surgery were used to compare nasolabial angle and projection between groups. Patients’ satisfaction with the cosmetic results and nasal obstruction were evaluated using the Standardised Cosmesis and Health Nasal Outcomes Survey (SCHNOS). LCC and MCC were each used in 26 cases. Preoperatively, the nasolabial angle, tip projection, and other characteristics were not significantly different between the groups. There was no significant difference in tip rotation stability (p = 0.624) and projection (p = 0.329) between the groups postoperatively, but patients’ satisfaction with the cosmetic results was significantly higher in the MCC group (p = 0.046). It seems that both LCC and MCC are effective techniques in rhinoplasty. Compared with LCC, the use of MCC in qualified hands may increase the patients’ satisfaction with the cosmetic results. © 2021 The British Association of Oral and Maxillofacial Surgeons
