OBJECTIVETo introduce an improved technique for Macrocheilia. The traditional technique for macrocheilia with direct suture and Z-plasty was improved to decrease postoperative complications, e.g. dynamic abnormality, obvious scar and recurrence due to scar contraction.

METHODSOutside of the new commissure, a triangle flap of the upper lip vermilion was designed, created and inserted to the lower lip. The orbicularis oris muscle was anatomically replaced. Skin Z-plasty was made with triangle flap transferring from the upper to the lower instead.

RESULTSSince August 1985, the new technique has been used in 12 cases of Macrocheilia. All the patients obtained satisfactory results with nice configuration and good function without dynamic abnormality and obvious scar.

CONCLUSIONThe new technique is a more reasonable method for macrocheilia with nice configuration, good function and fewer complications.
