[Reconstruction of nasal defects of multiple subunits with lateral nasal artery pedicled nasolabial flap].

To evaluate the effectiveness of the lateral nasal artery pedicled nasolabial flap for reconstruction of nasal defects of multiple subunits. From September 2014 to April 2016, 30 cases of nasal defects in multiple subunits repaired with the lateral nasal artery pedicled nasolabial flap were retrospectively analysed. All flaps survived. Incision at donor and accepted sites healed by first intention. Two patients had mild venous stasis 24 hours after operation and can alleviated spontaneously. Flap revision was performed in 25 cases after 3-6 months. Twentythree cases were followed up 3-12 months. All patients achieved satisfactory results in nasal appearance. The lateral nasal artery pedicled nasolabial flap can reconstruct the nasal defects of multiple subunits, and the texture, color or thickness are similar to the surrounding skin.It is one of the effective methods to repair multiple subunits of nasal defects.
