Reconstruction of columellar defects: Which surgical technique to choose? A retrospective study of 18 patients.

The reconstruction of the columella is challenging and poorly evaluated in the literature. Our study aimed to evaluate retrospectively the different techniques used in our center and to propose an algorithm of reconstruction adapted to each patient. We report a retrospective cohort study included 18 patients (9 men and 9 women; 53 years-old in average) with columellar reconstruction treated from 1999 through 2014. Six different techniques were used: chondrocutaneous graft, nasolabial flap, paramedian forehead flap and scalping flap according to the Converse technique or the Raulo technique. Four independent plastic surgeons evaluated the aesthetic result on a 10 cm visual analogue scale comparing the patients' photographs before and after the reconstruction. Furthermore, we asked the patients to perform the same evaluation, and to evaluate their level of satisfaction. The mean follow-up was 4 years. Three chondrocutaneous grafts were performed to reconstruct partial defects (Surgical Evaluation (SE): 7.9, Patient Evaluation (PE): 8.3).Three bilateral nasolabial flaps (SE: 6.1, PE: 6.7), 5 paramedian forehead flap (SE: 6.9, PE: 7.3) 6 Converse scalping flap (SE: 4.9, PE: 5.4) and 1 Raulo scalping flap (SE: 6,1, PE: 6,3) were performed to reconstruct total defects exceeding the columella. The use of composite graft was the most satisfactory procedure for partial defects. Paramedian forehead flaps and Raulo scalping flap were the most satisfactory procedures for extended defects. Nasolabial flap was the most adapted procedure for patients with general anesthesia contraindication or for defects extended to the lip.
