Effects of the Tongue-in-Groove Maneuver on Nasal Tip Rotation

Abstract

Background A change in nasal tip rotation is a very common maneuver performed during rhinoplasty. Among the many techniques used to achieve this goal is the tongue-in-groove (TIG). Objectives This study addresses the long-term effect of the TIG on the nasal tip rotation 1 year after rhinoplasty. Methods The authors prospectively identified patients who were submitted to a rhinoplasty with a TIG maneuver over a period of 1 year. The angle of rotation was measured along the nostril axis angle. The data were analyzed using the t test and a linear regression model. Results Seventeen patients were included. The average preoperative tip rotation was 93.95° (SD, 3.12°). Immediate postoperative tip rotation averaged 114.47° (SD, 3.79°). At the 1-year follow-up appointment, the tip rotation averaged 106.55° (SD, 3.54°). There was a significant loss of rotation at the 1-year postoperative visit (P < 0.0001), with an average loss of 7.9° (SD, 3.25°), which amounted to 6.8%. The preoperative rotation didn't affect the amount of loss of rotation (P = 0.04). It can be estimated that, for every degree of rotation that is changed at surgery, the tip can be expected to lose 0.35 degrees over the first year. Conclusions TIG is a more dependable technique than the ones that rely on healing and contraction to obtain rotation. Our data demonstrated a significant loss of rotation during the first year. This suggests that the surgeon needs to slightly overcorrect the tip rotation to account for this loss. Level of Evidence: 4
