Description
Summary:	PurposeTo report outcomes and complications of lower eyelid retractor recession and lateral horn lysis (RR) for lower eyelid elevation in patients with facial nerve palsy (FNP).Patients and methodsRetrospective review. Patients with FNP undergoing RR alone (group 1) or with adjunctive procedures (canthal suspension-group 2, tarsorrhaphy-group 3, and full-thickness skin graft-group 4) during a 5-year period were included. Patient demographics, lagophthalmos, occurrence of eyelid malpositions, recurrent retraction, and repeat procedures were noted from medical records. Measures of lower eyelid height (LEH) and lid lag on downgaze were obtained from standard photographs.ResultsForty-two patients (23 females, mean age was 59 years) were included. Mean follow-up was 24 months (range 6-77). Median improvement in LEH following surgery was significant in Group 1 (0.90 mm, IQR: 0.37-0.91, P=0.20) and in Group 2 (0.51 mm, IQR: 0.30-1.37, P
