Novel outpatient approach to lower lip reanimation using a palmaris longus tendon sling.

OBJECTIVE

To report a new approach to lower lip reanimation, which can be performed in the outpatient clinic setting.

STUDY

DESIGN

Cross-sectional study.

SETTING

Tertiary and quaternary care academic hospital, Toronto.

SUBJECTS AND

METHODS

An evaluation of nine patients with marginal mandibular nerve injury, who underwent harvest of the palmaris longus tendon and static suspension of the lower lip, was performed in the outpatient setting. Outcome measures included subjective self-evaluation of the functional and aesthetic results using the Lip Reanimation Outcomes Questionnaire and postoperative photographic grading of symmetry at rest and during three smile poses. Medical records were reviewed for demographics and complications.

RESULTS

Seventy-eight percent of patients reported overall improvements in smiling, oral competence, and speech articulation following tendon transfer. Photographic grading by the judging panel found satisfactory smile symmetry postprocedure.

CONCLUSIONS

The palmaris longus tendon sling procedure provides an effective, additional option for reanimation of the paralyzed lower lip.
