The exact mechanism for the formation of hematoma from nasal trauma is controversial, but thought to occur in nasal septal hematomas when there is forced to the nasal cartilage. The force causes the perichondrial blood vessels to leak and rupture in the nasal septum. [7] The cartilage in the septum is avascular and can be 2–4 mm thick.
Kiesselbach's plexus is an anastomotic arterial network (plexus) of four or five arteries in the nose supplying the nasal septum. It lies in the anterior inferior part of the septum known as Little's area, Kiesselbach's area, or Kiesselbach's triangle. It is a common site for anterior nosebleeds.
The posterior septal artery supplies blood to the respiratory region of the nasal septum, which consists of the lower two-thirds of the nasal septum and most of the nasal floor. [1] The path of the posterior septal artery can be understood by splitting it into three different segments.
The septum generally stays in the midline until about the age of seven, at which point it will frequently deviate to the right. An operation to straighten the nasal septum is known as a septoplasty. A perforated nasal septum can be caused by an ulcer, trauma due to an inserted object, long-term exposure to welding fumes, [6] or cocaine use ...
The greater palatine artery is a branch of the descending palatine artery (a terminal branch of the maxillary artery) and contributes to the blood supply of the hard palate and nasal septum. Course [ edit ]
The nasal septum divides the cavity into two cavities, [1] also known as fossae. [2] Each cavity is the continuation of one of the two nostrils. The nasal cavity is the uppermost part of the respiratory system and provides the nasal passage for inhaled air from the nostrils to the nasopharynx and rest of the respiratory tract.

The nasal branch travels through cribriform plate to enter the nasal cavity and runs in a groove on the deep surface of the nasal bone. Here it bifurcates into a medial and lateral branch. The lateral branch supplies blood to the lateral wall of the nasal cavity and the medial branch to the nasal septum.
