Purulent Discharge on the Pharyngeal Wall

A 31-year-old man presented with left facial discomfort over the maxillary sinus area lasting for one year. It was associated with hyposmia. He had a history of intermittent attacks of facial pains that responded temporarily to antibiotics. He had no history of allergy. On examination, tenderness was elicited over the left maxillary sinus. Intraorally, postnasal discharge was noted on the posterior pharyngeal wall. Nasal endoscopy revealed a greenish purulent discharge on the floor of the left nasal cavity originating from the left middle meatus. A radiograph was requested. The provisional diagnosis was left chronic maxillary sinusitis.
