dorsal nasal flap
A local skin flap from the nasal dorsum used to reconstruct nasal tip and alar defects while maintaining aesthetic subunits.
Full Definition
The dorsal nasal flap is a versatile local reconstruction option that utilizes excess skin from the nasal dorsum to repair defects of the nasal tip, supratip area, and alar regions. This flap respects the aesthetic subunits of the nose and provides excellent color and texture match. The blood supply comes from the angular and lateral nasal arteries, making it a reliable option for nasal reconstruction. The flap can be designed as an advancement flap or with rotation components depending on the defect geometry. Care must be taken to avoid creating secondary deformities of the nasal dorsum, and the technique requires precise planning to maintain nasal projection and tip definition.
Usage
Usage note: Always document the aesthetic subunits involved and preservation of nasal landmarks.
