Abstract Rationale: Periorbital cellulitis or an orbital abscess caused by acute sinusitis is a serious acute infectious disease. If not treated in time, serious complications may occur. Patient concerns: A 16-year-old girl with a history of right-sided proptosis, periorbital swelling, chemosis, hypophasis, restricted ocular movement in the upward direction, and diminution of vision was referred to our institution. The clinic, computed tomography (CT) and magnetic resonance imaging (MRI) examination indicate right orbital abscess in the upper quadrant and sinusitis. Diagnoses: She was diagnosed with orbital abscess, acute sinusitis. Interventions: She underwent medical management, transnasal endoscopic surgery and then ultrasound-guided fine needle aspiration (FNA) and catheter drainage. Outcomes: She was completely cured without any complications or sequelae. Lessons: Performance of surgical drainage in a timely manner and administration of effective antibiotic treatment according to bacterial culture can reduce the complications of orbital abscesses. Ultrasound-guided FNA and catheter drainage is a safe, simple, and effective method for the treatment of orbital abscess.
