The inferior nasal concha or turbinate is one of the conchae in the nose.

Gross anatomy

It extends horizontally along the lateral wall of the nasal cavity and consists of a lamina of spongy bone, curled upon itself like a scroll. Each inferior nasal concha is considered a ~~facial~~ pair of facial bones since they arise from the maxillae bones and projects horizontally into the nasal cavity.

Superior to inferior nasal concha are the middle nasal concha and superior nasal concha which arise from the cranial portion of the skull. Hence, these two are considered as a part of the cranial bones.

Surfaces

The medial surface is convex, perforated by numerous apertures, and traversed by longitudinal grooves for the lodgement of vessels. The lateral surface is concave, and forms part of the inferior meatus.

Borders

Its upper border is thin, irregular, and connected to various bones along the lateral wall of the nasal cavity. The inferior border is free, thick, and cellular in structure, more especially in the middle of the bone.

The upper border may be divided into three portions:

the anterior articulates with the conchal crest of the maxilla
the posterior with the conchal crest of the palatine
the middle portion presents three well-marked processes, which vary much in their size and form

~~Ossification~~

Development

The inferior nasal concha is ossified from a single ~~center~~centre, which appears about the fifth month of fetal life in the lateral wall of the cartilaginous nasal capsule.
