Normally, there are three pairs of nasal turbinates in the nasal cavity. Coronal computed tomographies of 253 cases of sinusitis were examined for the presence of additional turbinates and bilateral secondary middle turbinates were detected in two cases. Also, we describe another accessory turbinate, 'bifid inferior turbinate', in one of these cases. Existence of these accessory turbinates may occur during embryologic development of lateral nasal wall. (C) 1999 Elsevier Science Ireland Ltd. All rights reserved.
