Modified Endonasal Tongue-in-Groove Technique

Abstract

Achieving stable and desirable changes in tip rotation (TR) and tip projection (TP) is among the primary goals of modern day rhinoplasty. The tongue-in-groove (TIG) technique is one technique in rhinoplasty used to improve TR and/or TP. Performing TIG endonasally using a permanent suture can be quite cumbersome as the suture needs to be buried under the skin. We describe a variation of TIG technique for endonasal rhinoplasty using a permanent suture buried in small columellar skin incisions. The technique details are described and the postoperative changes in TR and TP are analyzed for the degree of change and longevity. A retrospective review of the preoperative and postoperative photographs of 12 patients treated with the endonasal TIG technique were analyzed for changes in TR and TP. Out of 12 patients, there were seven females (58.3%) and five males (41.7%), with age ranging from 17 to 49 years. The follow-up ranged from 6 months to 53 months, with mean follow-up of 12.1 months. All patients were treated by the senior author in a major New York City hospital. Postoperative changes in TR and TP were compared by measuring the nasolabial angle as well as the Goode ratio using a photo editing software. Using a t-test and a p-value criteria of 0.05, the difference between the preoperative and postoperative TR (p = 0.0069) and TP (p = 0.026) was found to be statistically significant. None of the study patients developed any complications related to the use of a permanent suture material during the follow-up period. Our modified TIG technique is a quick, reliable, and safe option in the surgical armamentarium to achieve desired changes in TR and/or TP.
