Surgical treatment of macrocheilia.

The authors report 27 cases of macrocheilia, discussing each cause individually. They classify macrocheilia according to its etiology, emphasizing the importance of an accurate diagnosis in treating the disease. The operative technique indicated for each cause is discussed. The technique basically consists of a fusiform resection, which may include a larger or smaller amount of lip tissue depending on the disease process. The incision may be interrupted at the mid-lip and W-plasty or lateral Z-plasties may be used to avoid the formation of dog ears.
