Association of Nasal Tip Rotation Outcome Estimation With the New Domes Technique in Primary Rhinoplasty.

Area of Science:

• Plastic Surgery
• Facial Plastic Surgery
• Rhinoplasty Techniques

Background:

• Accurate estimation of postoperative nasal tip rotation is crucial for surgical planning in rhinoplasty.
• The "new domes" technique is a specific surgical approach used in rhinoplasty.

Purpose of the Study:

• To evaluate the predictability of nasal tip rotation angle outcomes using the new domes technique in primary rhinoplasty patients.
• To determine if the degree of lateralization of nasal domes correlates with the final nasal tip rotation.

Main Methods:

• Retrospective analysis of 323 patients undergoing primary rhinoplasty with the new domes technique.
• Nasal tip rotation angle measured preoperatively, 1 week postoperatively, and 6 months postoperatively.
• Correlation between nasal dome lateralization (in millimeters) and rotation angle changes.

Main Results:

• The mean preoperative nasolabial angle was 92.7°, increasing to 105.5° at 1 week and 102.1° at 6 months postoperatively.
• A mean increase of 3.6° in rotation was achieved per millimeter of nasal dome lateralization.
• The mean rotation angle showed a slight decrease of 3.4° between 1 week and 6 months postoperatively.

Conclusions:

• The new domes technique is a reliable and reproducible method for achieving predictable nasal tip rotation in rhinoplasty.
• Despite inflammatory changes, precise measurement of nasal dome lateralization allows for accurate prediction of long-term nasal tip rotation.
• This technique enables surgeons to preoperatively determine the definitive nasal tip rotation angle.
