Case in brief

Two patients developed unilateral orbicularis oculi paresis after lower blepharoplasty with supraperiosteal orbital fat transposition for tear trough deformity. Videos obtained 2 weeks after surgery showed reduced blink amplitude in the affected eye: patient 1, OD 3.14 mm versus OS 8.43 mm; patient 2, OD 4.33 mm versus OS 8.50 mm. By 6 months, blink amplitude was symmetrical in both patients, and symptoms of ocular exposure had resolved.

What made this case unusual

The postoperative paresis was documented objectively by reduced blink amplitude and was associated with ocular exposure symptoms, but resolved by 6 months.

Diagnostic / clinical pearl

Motor fibers to the pretarsal orbicularis oculi follow a sub- and intramuscular course in the medial lower eyelid; surgery in this region may injure them and cause paresis.

Why it matters

The authors suggest that a subperiosteal approach to orbital fat transposition may help avoid this complication.
