Abstract：Objective To explore the clinical efficacy of the nasolabial perforator flap in the repair of nasal soft tissue defects.Methods A Doppler blood stream detector was used to trace the facial artery and discover the locations of the perforator arteries from 1.5 cm below the inner canthus to the otis angulus before surgery.Nasolabial perforator flaps formed based on the perforate branch of facial artery were used to reconstruct defects of the nasal soft tissue.The ratio of the length and width of the flap ranged up to 9:1.The thickness of the subcutaneous fat was approximately 2.0 to 3.0 mm.The reconstructed area of the nasal soft tissue was from 1.2 cm × 1.6 cm to 2.7 cm × 3.1 cm.A total of 8 cases were included in this study.Results All flaps survived.Venous crisis occurred in 2 cases,which was relieved by partial removal of sutures.All cases were followed up from 5 to 24 months.The color,texture,and appearance of the flap was satisfacto ry.The flaps were not bloated.The nose shape was natural.Conclusion The nasolabial perforator flap has a reliable blood supply without vascular anastomosis.It can support a large area flap incision.The subcutaneous pedicle was narrow and long,and the flap thickness was appropriate.The nasolabial perforator flap allowed surgeons to overcome the shortcomings of the nasolabial random flap and the nasolabial facial artery flap.As the nasolabial flap can enable better reconstructive efficacy in the nasal soft tissue,it should be considered for promotion in clinic.
