A 4-year-old girl with maxillary hypoplasia, intermittent exotropia, and high myopia displayed congenital oculonasal synkinesis. We examine the implications for pathogenesis of these disparate craniofacial findings.

Synkinesis represents involuntary muscular movements that occur in association with voluntary contraction of other muscle groups. Oculonasal synkinesis is a rare phenomenon.. In a series of videos, the authors present clinical findings and surgical correction of oculonasal synkinesis.. Two women who underwent surgical procedures to correct oculonasal synkinesis were evaluated in a prospective study. One patient presented with bilateral synkinesis after 2 previous rhinoplasties. She underwent open rhinoplasty in our office. The other patient had unilateral synkinesis of the left side and received endonasal rhinoplasty.. The patients' mean age was 27.5 years, and follow-up was conducted for 6 months. Both patients experienced complete, stable resolution of synkinesis after surgical correction. No complications were recorded.. Patients with oculonasal synkinesis may not notice it preoperatively and may regard these muscle movements as an unfavorable result of rhinoplasty. Therefore, careful preoperative evaluation is crucial.

Facial synkinesis is the simultaneous contraction of the certain facial musculature accompanying a motion of designated muscle in the face. With the exception of rare afflictions that are congenital in origin, most patients develop as a sequel to facial nerve paralysis due to trauma, tumor, and surgical injury. As an idiopathic congenital form, oculo-nasal synkinesis which reveals co-contraction of orbicularis oculi and the compressor narium minor muscles which are innervated by separate branches of the facial nerve have been already reported. In addition to oculo-nasal synkinesis, the authors describe 2 more rare patients with facial synkinesis; oculo-zygomatic and fronto-nasal synkinesis with video documentation, which to the best of our knowledge, have not been reported previously in detail. This will help plastic surgeons prevent being involved in legal issues when they might neglect these rare phenomena in preoperative evaluation during cosmetic surgery.

Oculonasal synkinesis is the simultaneous contraction of the orbicularis oculi and the compressor narium minor muscles. The etiology of this phenomenon is still unclear; congenital and traumatic reasons are considered to be responsible. Here we report a case of oculonasal synkinesis.
