CONCHA-BULLOSA

Concha bullosa is one of the most common, obstructive, anatomic varian ts seen in patients with sinusitis. In this study, a total of 160 pati ents with sinusitis were evaluated to study both the effects of concha bullosa on the distribution of opacification to the paranasal sinuses as well as the relations between the types of concha bullosa (CB) and ostiomeatal complex disease (OMCD). Our results show that CB does not necessarily have influence on the distribution of mucosal changes to paranasal sinuses. Furthermore, in the presence of OMCD, no significan t difference statistically was found between patients with CB and thos e without. However, when the types of CB are considered, OMCD is found to be more frequent if the pneumatization is localized to the inferio r half of the middle turbinate, such as in bulbous and extensive types of CB.
