Abstract
Concha bullosa (CB) manifests as a commonly encountered anatomical variant within the middle turbinate; nevertheless, the incidence of sinusitis attributable to CB is notably uncommon. This case represents chronic rhinosinusitis associated with an unusually massive bilateral CB reaching the floor of the nasal cavity which was treated surgically by performing functional endoscopic sinus surgery and partial middle turbinectomy. This case report aims to contribute to the existing knowledge in the field of otolaryngology by elucidating the surgical options associated with massive middle turbinate CB and ultimately improving the care provided by otolaryngology surgeons for patients with similar conditions.
