(From Grabb and Smith CD-ROM:)

 

The Karapandzic technique utilizes lip tissue by the use of advancement and rotation of segments of skin, orbicularis muscle, and mucosa following the division of the other supporting muscles. This procedure redistributes the remaining lip tissue and allows the neurovascular supply to remain intact. Its advantage is the preservation of motor and sensory function. The disadvantages include microstomia and the need for extensive circumoral incisions and dissections.
