Objective: To report a case of a large sinus Haller cell that presented with chronic rhinosinusitis and proptosis and its surgical management.
Design: Case Report
Setting: Tertiary Government Hospital
Results: A 34-year-old lady with proptosis and secondary sinusitis due to a giant infected Haller cell was successfully treated by lateral rhinotomy approach and clearance of all diseased mucosa therein into the nasal cavity.
Conclusion: Approach to diseased sinonasal structures via lateral rhinotomy is an alternative to endoscopic sinus surgery in the presence of an unusually large Haller cell.
