Surgical Correction of a Bifid Nose Deformity with a Split M-Shaped Flap

Abstract

Background:

Bifid nose is a representative indicator of a facial cleft in patients with frontonasal dysplasia. There is no consensus on effective methods to correct bifid nose deformities due to their varied expressions and limited reports of surgical treatments. In this article, we propose using a split M-shaped flap to treat severe dorsal and alar deformities in patients with a bifid nose.

Methods:

From 2012 to 2021, a total of 26 bifid nose patients underwent surgical correction of their nasal deformities, which were characterized by cleft and board dorsum, alar defects, shortened nose, and shortened or absent nasal tip. These surgeries were performed with the transposition of an M-shaped split flap. Nasal length and nasolabial angle were assessed before and after surgery. Indications, outcomes, and complications were analyzed. Patient satisfaction was evaluated using a self-assessment survey.

Results:

Postoperative evaluation showed stable results with increased nasal length and improved nasal appearance. Complications were seen in difficulty breathing through the nose and persistent nostril deformities. The majority of patients (92.3%) were satisfied with their surgical outcome.

Conclusion:

Split M-shaped flap for bifid nose treatment provides improved nasal appearance with a high patient acceptance and stable postoperative results. Clinical Trial registration: chictr.org identifier ChiCTR2000039275
