Correction of severe bifid nose deformity using an open W-shaped incision.

Background: Bifid nose is a rare congenital anomaly. Because of its low incidence, few cases of surgical treatment have been reported. We propose a surgical method using an open W-shaped incision as a treatment option for severe bifid nose. Based on our 10-year experience, we describe the technique and discuss outcomes, patient selection, and complications.

Methods: From May 2009 to December 2020, 32 patients with bifid nose underwent surgical correction of the nasal deformity characterized by dorsal hypertelorism, midline cleft of nasal bone and cartilage, and shortened nose using an open W-shaped surgical incision. Nasal subunit morphology before and after surgery was measured by three-dimensional simulation technology. Indications, outcomes, and complications including possible underlying reasons were analyzed. Patient satisfaction was evaluated using a self-assessment survey.

Results: Correction of the bifid nasal deformity was successfully achieved using an open W-shaped surgical incision with increased nasal length and improved nasal appearance. Patients were followed-up for a period of 10 months on average, ranging from 6 months to 10 years. Follow-up examinations demonstrated stable results. The overall complication rate was 1.9%. Complications included temporary scar, ventilation disorder, and mild infection of the nasal skin. The majority of patients (98.1%) rated their outcome as improved and much improved (Table 1).

Conclusion: The open W-shaped incision technique is an effective therapeutic approach for the correction of severe bifid nose. This is a simple and safe method for the treatment of bifid noses with a high patient acceptance and stable postoperative results.
