Inferior nasal concha

The inferior nasal concha, concha nasalis inferior, is a paired, curved bony plate (Fig. 48A) featuring the following processes: the maxillary process, processus maxillaris, the ethmoidal process, processus ethmoidalis, and the lacrimal process, processus lacrimalis. The maxillary process, processus maxillaris, is the largest; it projects inferiorly and partially closes the inferior margin of the maxillary hiatus. The lacrimal process, processus lacrimalis, participates in forming the articulation with the Lacrimal bone. The ethmoidal process, processus ethmoidalis, arises near the junction of the maxillary process with the bone body. It presents two surfaces: a lateral (concave) surface and a medial (convex) surface. The anterior portion of the superior end of the inferior concha attaches to the conchal crest of the Maxilla, while its posterior portion attaches to the conchal crest of the Palatine bone. The space beneath the inferior concha is termed the inferior nasal meatus, meatus nasalis inferior.

Ossification. An ossification center appears in the Cartilage of the nasal concha during the 4th month of intrauterine development.
