Abstract
We experienced three patients with long-standing unilateral complete facial paralysis who previously underwent temporalis muscle transfer to the cheek for smile reconstruction. All patients complained of insufficient and uncomfortable buccal motion synchronised with masticatory movements and incomplete eyelid closure with ptotic eyebrow. To attain a near-natural smile and reliable eyelid closure, temporalis muscle was displaced from the cheek to the eyelid, and a neurovascular free latissimus dorsi muscle was transferred for the replacement of cheek motion. As a result, cheek motion synchronised with the contralateral cheek upon smiling and sufficient eyelid closure were obtained in all cases. Smile reconstruction using the temporal muscle is an easy and a versatile way in general. However, spontaneous smile is not achieved and peculiar movement of the cheek while eating is conspicuous in some cases. Replacement with neurovascular free latissimus dorsi muscle and recycling previously used temporalis muscle for eyelid closure are considered to be valuable for such cases.
