Introduction: Many varied sinus pathologies can present with orbital involvement and sinusitis is one of the leading causes of orbital complications in developing countries. This study was done to evaluate the spectrum of orbital complications of rhinosinusitis. Methods: A retrospective study was carried out involving the cases of orbital involvement complicating rhinosunisitis and 17 cases were included in the study.Result: In our series, patients with male to female ratio of 3.25:1 and higher occurrence was observed in pediatric age group (71%). In the present study, CT scan revealed orbital cellulitis in 7 cases (41%) followed by preseptal cellulitis in 6(35%), orbital abscess in 2(12%) , subperiosteal abscess in 1(6%) and eyelid abscess in 1(6%). The most common pattern of sinus involvement in our series was combination of ethmoid and maxillary sinuses. 14 patients (82%) underwent endoscopic orbital decompression, 2 patients (12%) underwent endoscopic optic nerve decompression in conjunction with orbital decompression and 1 patient (6%) underwent external incision and drainage for eyelid abscess. Conclusion: Orbital complications of acute rhinosinusitis is a medical as well as surgical emergency. Surgical decompression and drainage in conjunction with aggressive medical management remains the standard of care for this condition to achieve a good prognosis and visual outcome.
