The jaw-winking syndrome

Area of Science:

• Ophthalmology
• Neurology
• Genetics

Background:

• Jaw-winking syndrome, or pterygoid-levator synkinesis, is a rare congenital condition characterized by the retraction of the upper eyelid during mandibular movements.
• While often diagnosed in infancy, its presentation in adulthood can indicate underlying neurological or ophthalmological comorbidities.
• Oral health care providers are uniquely positioned to identify this condition due to its elicitation by jaw movements.

Observation:

• This report details the incidental discovery of jaw-winking syndrome in a 22-year-old Asian male during a routine examination.
• The patient presented with no reported physical or psychological distress related to the condition.
• An associated, previously corrected, ophthalmological defect was noted in the patient.

Findings:

• The case highlights that jaw-winking syndrome can manifest and be identified in young adults.
• The incidental finding underscores the importance of thorough clinical observation, even in asymptomatic individuals.
• The presence of a corrected ophthalmological issue suggests a potential link or co-occurrence with other visual system anomalies.

Implications:

• Early diagnosis of jaw-winking syndrome, particularly in neonates, can facilitate timely management of associated ophthalmological conditions.
• Oral health professionals should be aware of jaw-winking syndrome as a potential sign, prompting referral for further evaluation.
• This case broadens the understanding of the adult presentation of jaw-winking syndrome and its clinical significance.
