Prospective evaluation of eyelid function with gold weight implant and lower eyelid shortening for facial paralysis.
OBJECTIVE
To assess which signs and symptoms were relieved by gold weight implantation and which signs and symptoms persisted.


METHODS
Prospective observational cohort.


METHODS
Tertiary care neurotology and oncology center.


METHODS
Sixteen (4 males and 12 females) consecutive patients whose average age was 56 years (age range, 31-76 years). Inclusion criteria were gold weight implant, lagophthalmos of 2 mm or more, and a House-Brackmann score of 3 or less at the completion of follow-up. Mean follow-up was 13 months.


METHODS
Each patient received a gold weight implant. Six of these patients underwent a lower eyelid procedure.


METHODS
Surgical complications, static and dynamic lagophthalmos, static and dynamic corneal coverage, visual acuity, keratitis, topical treatment, and patient satisfaction.


RESULTS
There were no extrusions. The preoperative mean lagophthalmos was 7.5 mm and the postoperative mean was 0.5 mm, (P<.001). Corneal coverage with eye closure before implantation was 73% and after implantation was 100%, (P<.001). Corneal coverage with normal (reflex) blink was less than 50% in 9 of 14 patients. When wearing correction, no patients had 20/20 visual acuity. The mean patient satisfaction score before the procedure was 3.5 and after was 7.1, (P<.001). Patient satisfaction was most closely related to visual acuity. The relationship was linear and statistically significant (P<.04).


CONCLUSIONS
Gold weight implantation provides significant reduction in lagophthalmos and significant improvement in corneal coverage. But owing to delayed closure time and disrupted tear film, irritation may persist. As a result, some patients require ongoing topical treatment of the eye, which can compromise visual acuity.
