Abstract

Orbital abscess is a frequent complication of pediatric acute sinusitis requiring surgical drainage combined with FESS. The preseptal transconjunctival approach provides safe orbital access, enabling effective drainage while preserving ocular function and avoiding facial scarring. We aimed to describe the case of a child with an orbital abscess treated with preseptal transconjunctival drai-nage combined with ESS. A 9-year-old boy presented with fever, purulent rhinorrhea, and left periorbital swelling. Computed tomograph showed left maxillary and ethmoidal sinusitis with an 8mm extraconal intraorbital abscess. After no improvement with intravenous antibiotics, he underwent FESS combined with preseptal transconjunctival abscess drainage. By postoperative day 7, complete resolution of infection and full recovery of ocular function were achieved. This case highlights timely surgical intervention in pediatric orbital complications of acute sinusitis. The combi-ned FESS and preseptal transconjunctival approach achieved infection control, preserved ocular function, and avoided scarring, supporting transorbital approaches in infectious orbital pathology.
