One stage nasolabial flaps are used for small superficial defects within the sidewall or nasal ala.
In this authors experience, the use of local nasal flaps (bilobed or dorsonasal flaps) may lead to adjacent landmark distortion. Because there is limited excess lax skin within the nasal surface, there is not enough skin to share. Skin must be added to the nasal surface, not redistributed. This risk can be minimized by using the one stage nasolabial flap which adds cheek skin to the nose.
