Özet

Chronic nasal obstruction is a common disorder. Hypertrophy of the inferior turbinates is responsible for nasal obstruction more frequently than it is commonly thought. A pneumatized inferior turbinate has recently been described as a cause for nasal obstruction and only two cases have been reported until now. Inferior nasal turbinate develops by endochondral ossification of components of the mesethmoid and ectethmoid. The chondral framework of the inferior turbinate consists of a double lamella and two separate ossification centers that develop between the fifth and seventh month of fetal life. The separate ossification centers meet by the eighth fetal month. During ossification, the inferior turbinate detaches from the ectethmoid and becomes an independent bony structure. During that time the epithelium may misinvaginate into double lamellas and such double lamellas formed by the inferior turbinate may become persistent.
