 In a study of chronic unilateral facial nerve palsy sequelae, 56 patients with poor recovery characterized by orbicularis oculi spastic paralysis and pathological synkinesis (excluding flaccid complete paralysis) were treated with various combinations of periocular reconstructive procedures tailored to the patientsʼ individual symptoms. These procedures included brow lift surgery, levator aponeurosis advancement and frontalis suspension as upper eyelid surgeries, and partial resection of the orbicularis oculi muscle in the upper eyelid and lateral canthal region.

 Although no statistically significant differences in postoperative aesthetic outcomes were detected among the different surgical techniques, the group of patients for whom partial resection of the lateral canthal orbicularis oculi was performed showed an evidently greater aesthetic improvement compared to the counterpart groups receiving equivalent combinations of procedures without this technique. In addition, in the 10 patients who underwent partial resection of the lateral canthal orbicularis oculi, both the vertical palpebral fissure height on the paralyzed side at rest and the corresponding height during synkinesis showed statistically significant postoperative improvement.

 Partial resection of the lateral canthal orbicularis oculi can be performed with the patient under local anesthesia in an outpatient setting and is minimally invasive, requiring relatively limited medical resources. This procedure should therefore be considered a high-priority surgical option for the treatment of palpebral fissure narrowing associated with facial nerve palsy sequelae.
