Facial reanimation by transposition of the masseter muscle combined with tensor fascia lata, using the zygomatic arch as a pulley.

摘要

We have created a new way of reanimating the face, involving transposition of the masseter muscle combined with tensor fascia lata, and using the zygomatic arch as a trochlea to reconstruct the inferior facial paralysis. We used it on five patients who had facial palsy after excision of malignant parotid tumours. The wide skin defect that exposed the masseter muscle after total parotidectomy was reconstructed with a free flap. This method differs from those of other methods of transposing the masseter muscle in that force is applied at an upper lateral angle. Our method provided dynamic raising of the upper lip, the corner of the mouth, and the nasolabial fold in four patients. We consider it to be useful, particularly for prompt surgical reconstruction of facial palsy after total parotidectomy with a wide defect in the skin of the cheek.
