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 separates the left and right airways in the nose, dividing the two nostrils.It is depressed by the depressor septi nasi muscle.The fleshy external end of the nasal septum is sometimes also called columella. The nasal septum contains bone and hyaline cartilage.The nasal septum is composed of five structures: perpendicular plate of ethmoid bone vomer bone cartilage of the septum Nostrils (nares): Your nostrils are holes that lead to your nasal cavities. Paranasal sinuses: These air-filled pockets connect to your nasal cavities. They produce the mucus that keeps your nose moist. Septum: This is the bone and cartilage that separate your nasal cavities. The lower part of your septum sits between your nostrils. The nasal septum is in the midline of the nose and made of flat cartilage anteriorly and bone posteriorly. 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.

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.
