Clinical efficacy of facial artery perforation nasolabial flap in reconstruction of nasal defect

Abstract

Objective To evaluate the effects of nasolabial flap with facial artery and its branches perforator for reconstruction of nasal defect. Methods Between March 2013 and April 2017, 21 patients underwent operations for the reconstruction of nasal defect, caused by trauma, surface tumors, moles and infection. The size of the defect was 1.5 cm × 2.0 cm to 3.0 cm × 3.0 cm. Designed various nasolabial perforator flap was pedicled with the facial artery. The pulsed blood flow detector determined the location of the facial artery and its perforation position, which was the rotation point, and the rotation of the nasolabial fold flap covered the nasal defect area to repair. Results 21 flaps survived. Surface artery perforation nasolabial fold flap was good blood supply, of which 1 case of flap was congested and recovered after treatment. After 1 month to 3 years follow-up on 21 cases, 20 cases showed good results and 1 case had generally accepted. The color, shape and function of the flap were significant, similar to the normal skin. Conclusions A small area defect in the nose is preferred by using facial arterial perforation nasolabial fold flap repair, which does not need secondary repair, and is worthy of clinical application.
