ABSTRACT
Concha bullosa (CB) is not considered to be a disease, but rather a variation of the paranasal sinus. A CB is defined as the presence of an air cell within the turbinate (pneumatization). The main function of CB is to maintain upper respiratory humidity, regulate thermoregulation, and regulate airflow and filtration. It is common for CB to occur in the middle turbinate, while superior and inferior locations appear to be rare. The patient in this case report was presented mainly with nasal obstruction. During examination, a large mass was found in the left nasal cavity, causing a deviated nasal septum to the right. For this patient, surgery was the last resort. Either perioperative or postoperative complications were observed, and the quality of life of patients improved after surgery.
