Acute isolated ptosis after dental treatment: A case report and literature review.

BACKGROUND

Isolated ptosis due to sinusitis without accompanying symptoms, such as ophthalmoplegia or orbital cellulitis, is rare, with few cases reported in the literature and none linked to dental procedures.

CASE DESCRIPTION: The authors describe a rare instance of isolated left-sided ptosis in a 5-year-old girl after dental treatment under nitrous oxide sedation. Computed tomographic imaging revealed pansinusitis without intraorbital complications. Proposed mechanisms included inflammation exacerbated by means of bacterial spread after the dental procedure and the use of nitrous oxide as well as possible compression of the superior division of the oculomotor nerve. Treatment with intravenous antibiotics led to near-complete resolution of ptosis within 5 days.

PRACTICAL IMPLICATIONS: Outcomes of this case highlight the importance of recognizing isolated ptosis as a rare complication of rhinosinusitis, particularly in pediatric patients. Prompt diagnosis and timely management are essential to prevent further complications.
