<p><b>New page</b></p><div>'''Piriform aperture''' is a term used in [[anatomy]] to describe the anterior nasal aperture, which is pear-shaped, hence the name 'piriform', derived from the Latin words 'pirum' (pear) and 'forma' (shape). It is the opening in the skull where the [[nose]] and its cavities are located. <br />
<br />
==Etymology==<br />
The term 'piriform aperture' is derived from the Latin words 'pirum', meaning pear, and 'forma', meaning shape. This is due to the pear-like shape of the anterior nasal aperture.<br />
<br />
==Anatomy==<br />
The piriform aperture is the anterior opening of the nasal cavity. It is bounded by the [[nasal bone]] superiorly, and by the [[maxilla]] on either side. The shape of the piriform aperture is significant as it determines the shape of the nose and the nasal airway. <br />
<br />
The piriform aperture is closely related to the [[nasal septum]], which divides the nasal cavity into two. The size and shape of the piriform aperture can be affected by deviations of the nasal septum.<br />
<br />
==Clinical significance==<br />
The size of the piriform aperture is of clinical significance. A narrow piriform aperture can cause [[nasal obstruction]], leading to difficulty in breathing. This can be corrected surgically by a procedure known as piriform aperture enlargement.<br />
<br />
In forensic medicine, the piriform aperture is used to determine the sex and race of a skull. The shape and size of the piriform aperture vary among different races and between the two sexes.<br />
