Reconstruction of the nasal midvault is an important component of successful rhinoplasty outcomes. Use of the autospreader flap is a beneficial technique for preserving the middle vault. In the present study, we evaluated the aesthetic and functional outcomes of this technique in patients without notable dorsal hump reduction.
A nonrandomized clinical trial was performed from December 2017 to April 2018 with a minimum follow-up time of 6 months. From among patients seeking rhinoplasty, 38 patients were eligible for inclusion in the study. The autospreader flap was used to recreate the middle vault in patients undergoing open rhinoplasty with up to 2 mm bony and cartilaginous dorsal hump removal. Preoperative and postoperative standard photographs were obtained. Assessment of patients was based on Rhinoplasty Outcome Evaluation (ROE) and Nasal Obstruction Symptom Evaluation Scale (NOSE) scores. Objective assessment included quantitative analysis of anthropometric angles, mean dorsal width, nasal length and projection which was performed on standard pre- and postoperative photos.
Overall, patients had statistically significant improvement in their postoperative NOSE scores (9 vs. 6.92, p=0.0001). The majority of patients were satisfied with the postoperative appearance of their noses. The mean nasal dorsal width (NDW) decreased postoperatively (43% vs. 36%). No difference was found between the mean height of the nose and projection pre- and postoperatively. There was a significant postoperative increase in the nasolabial angle and reduction in nasal length.
The autospreader flap is an effective technique in preservation and restoration of the middle vault and dorsal aesthetic line in cases with
less than 2 mm dorsal hump reduction. Nasal function can be improved while achieving good cosmetic outcomes
