Nélaton’s operation: the sutures.
Incision, when necessary, may be extended around the angle of the nose on one side or both, and the lip should be dissected away from the bone sufficiently to make it movable. Operations by which a certain dovetailing of the little flaps is performed afford more security than a perfectly straight incision, but the resulting scar is rather more marked. The more perfectly the mucous membrane can be preserved upon the under side of the lip the better will be the result.
