Abstract: Objective To evaluate the effect on reconstructing nasal subunits using nasofacial groove pedicle flap and its advantages and disadvantages. Methods From January 2015, total 15 cases with nasal defects due to tumor or trauma on different parts of nasal subunits, including nasal ala and nasal tip were treated with nasofacial groove pedicle flap for nasal reconstruction. Each flap was designed specifically based on the area of defect and then rotated to cover the wound surface. Conditions of both donor and recipient sites were monitored and evaluation of the nasal area were carried out by utilizing three-dimensional (3D) laser scanning. Results All 15 cases shown positive results on the survival rates of flaps, and minimal scars on both donor and recipient sites. Patients' satisfaction rates were high. 3D laser scanning shown regular appearance on the nasal area postoperatively. Conclusion Using nasofacial groove pedicle flap to repair nasal subunit defects is a promising method due to good appearance of recipient site and minimal damage of donor site.
