Summary

Oculonasal synkinesis, a simultaneous contraction of eye and nose muscles, was observed in 13 females. Surgical removal of the compressor narium minor muscle successfully eliminated this condition in patients.

Area of Science:

  • Neurology
  • Ophthalmology
  • Plastic Surgery

Background:

  • Oculonasal synkinesis is a newly identified condition involving involuntary facial muscle contractions.
  • It presents as simultaneous blinking (orbicularis oculi muscle contraction) and nasal ala depression (compressor narium minor muscle contraction).

Purpose of the Study:

  • To describe the clinical presentation and potential etiology of oculonasal synkinesis.
  • To evaluate the efficacy of surgical intervention for this condition.

Main Methods:

  • Observation of 13 individuals with oculonasal synkinesis across two practices.
  • Review of potential neurological underpinnings, specifically aberrant facial nerve connections.
  • Assessment of surgical outcomes following compressor narium minor muscle resection in 6 patients.

Main Results:

  • The phenomenon was exclusively observed in 13 female patients, with varying laterality (bilateral, right, left).
  • A familial link was suggested by its presence in a patient's infant daughter.
  • Resection of the compressor narium minor muscle led to complete resolution of symptoms in all 6 surgically treated patients.

Conclusions:

  • Oculonasal synkinesis is a distinct facial nerve synkinesis potentially arising from anomalous nerve branching.
  • Surgical resection of the compressor narium minor muscle is an effective treatment.
  • Plastic surgeons should be aware of this condition to inform patients and manage expectations, especially concerning rhinoplasty outcomes.
