Correction of nasal tip deformity using an island flap of nasal dorsum.

ABSTRACT

Bifid nose is a rare congenital malformation, and few cases have been reported due to its low incidence. Herein, we report a new surgical procedure to treat patients with excess dorsal nasal tissue and an underfilled tip. A total of 22 patients with bifid nose deformities underwent surgery at our institution between 2012 and 2022. They were characterized by a broad nasal dorsum and a missing or underdeveloped nasal tip. We designed an innovative island flap of nasal dorsum as a new surgical method for treating this bifid nose deformity. Nasal length, tip projection, and photographs of nose morphology were obtained before and after the surgery. Outcomes, complications, indications, and patient satisfaction were analyzed and interviewed. The follow-up time ranges from 6 to 33 months (8.7 ± 5.5 months). The deformity was successfully corrected with an improved nasal appearance. Nasal length increased from initially 4.2 ± 0.3 mm to 4.6 ± 0.3 mm. Tip projection reached 19.9 ± 4.0 mm, which was 15.7 ± 2.9 mm before surgery. No severe complications were observed except poor venous reflux within postoperative 72 hours in four cases. Six patients (27.3%) got moderate healing and acceptable scars, and 14 patients (63.6%) got good healing. Most patients were very satisfied with the outcome (93.9%). The newly designed nasal dorsum island flap is a safe and effective technical approach to correct nose deformity featured by broad nasal dorsum and a missing or underdeveloped nasal tip.
