Surgical Approach to Inferior Concha Bullosa: A Case Report and Literature Review

Abstract

Inferior concha bullosa is a rare anatomic variation in the nasal cavity and is usually asymptomatic. There is no specific algorithm for surgical approaches to be used for treatment in symptomatic cases. In this case report, we suggest that surgical planning should be done considering the anatomical features of inferior concha bullosa. Here, we present a case of inferior concha bullosa connected with the maxillary sinus. On the basis of the current literature, this patient was treated with a different surgical approach, including partial inferior turbinectomy preserving mucosa on the medial side and repairing the window with a mucosal flap. The anatomical relationship between the inferior turbinate and maxillary sinus is important in determining the surgical approach to inferior concha bullosa. In the surgical treatment of inferior concha bullosa connected with the maxillary sinus, repairing the window between the maxillary sinus and nasal cavity is important to prevent maxillary recirculation. Preoperative radiological evaluation is essential to understand the anatomical relationship more precisely.
