Pathology of the nose

A variety of diseases can affect the nose and paranasal sinuses. There are several paired paranasal sinuses, including the frontal, ethmoid, maxillary and sphenoid sinuses. The most common problem is sinusitis. Tumors arising from the nose and paranasal sinuses and trauma to the nose are other affilictions of the nose. Diagnosis is made by radiology and endoscopy. Treatment can be conservative or surgical. Endoscopic Sinus Surgery is the mainstay of most forms of surgical intervention.

Nasal septum

The nasal septum is the medial wall of each nostril. The basic components of the nasal septum are a quadrangular cartilage, perpendicular plate of ethmoid and the vomerine bone. The quadrangular lamina thickens at the upper region and is in continuity with the perpendicular plate of ethmoid making an osseo-cartilaginous continuity.



Sinusitis or rhinosinusitis is inflammation of the paranasal sinuses. It can be due to infection, allergy, or autoimmune issues.



The nasal polyposis is a disorder that occurs in 1-4% of the population. This incidence increases significantly if they are considered some groups of people with different nasal diseases.


Inverted papilloma

The inverted papilloma of the paranasal sinuses (also known as papilloma papilloma Schneideriano or transitional) is a benign tumor that originates from the lateral wall of the nose and extends to the paranasal sinuses.
