The anterior portion is made of irregular quadrangular hyaline cartilage that inserts into the nasomaxillary crest of the maxilla and nasal spine. Oneal RM, Beil Jr RJ, Schlesinger J.

A. Nasal Septum. The nasal septum is a thin wall inside the nose that separates the nasal cavity into left and right sides, creating two nostrils. At the front, the visible part called the columella nasi, is made of soft tissue and cartilage. The septum itself is about 2 mm thick and is built from a mix of bone and cartilage.

The nasal septum is a thin, vertical structure that divides the nasal cavity into two symmetrical halves—left and right. It is made up of both bone and cartilage, providing support and shape to the nose.[8] Atlas of Human Anatomy. 7th ed. Elsevier; 2018. ISBN 978-0323393225. McMinn RMH, Hutchings RT, Logan BM. The nasal septum (Latin: septum nasi) separates the left and right airways of the nasal cavity, dividing the two nostrils.

Sometimes, the septum takes the shape of a V, blocking one nostril completely. In other instances, it assumes an S shape, obstructing both nostrils. A deviated septum can lead to breathing difficulties, snoring, sleep apnea, and increased susceptibility to sinus infections. To assess the septum and its position, doctors use a nasal speculum.
