Orbicularis transposition: concept of a functional correction of uni- or bilateral paralysis of the lower lip.
A concept is described for the correction of the lower lip in cases of uni- or bilateral paralysis following injuries of the mandibular branch of the facial nerve, by transpositioning the affected orbicularis muscle to the innervated parts of the upper lip and the zygomatic muscle respectively. The surgical procedure is demonstrated in detail on the basis of several examples. Positive results are clinically and electromyographically evident. Therefore other techniques have been abandoned by us in favour of the transposition of the orbicularis muscle, which is simple in practice and ensures functionally and aesthetically successful results.
