Nasenbeine

Nasenbeine (nasal bones) are the two small, rectangular bones that form the upper part of the nasal bridge in humans and many mammals.

Each nasal bone lies at the midline and articulates with the frontal bone at the frontonasal suture, with the maxilla on the sides, and with the other nasal bone at the internasal suture.

Function: They help form the dorsum of the nose and contribute to the medial wall of the nasal cavity.

Development and variation: They ossify intramembranously, vary in size and shape among individuals and populations, and may be involved in nasal deformities after trauma.

Clinical relevance: Nasal fractures frequently involve the nasal bones and may require reduction; imaging is used to assess alignment.
