Ptosis Evaluation for Otolaryngologists

Ptosis, or blepharoptosis, is the abnormal drooping of the upper eyelid, which can obstruct vision, reduce visual function, and impair aesthetics. It results from dysfunction in eyelid-elevating muscles, such as the levator palpebrae superioris or Müller's muscle, and may present as congenital or acquired. Symptoms and findings include eyelid fatigue, superior vision loss, and compensatory brow elevation, significantly affecting quality of life. Common causes range from age-related changes to systemic conditions like MG and Horner syndrome. Comprehensive evaluation - considering onset, progression, associated symptoms, trauma, and systemic conditions - is essential. Treatment involves addressing the underlying cause, with surgical correction being the primary approach for functional and cosmetic restoration.
