This document discusses neoplasms of the nose and paranasal sinuses. It begins by stating that these neoplasms are rare, comprising 3% of cases, and are often misdiagnosed as benign conditions due to similar symptoms. The nose has an approximately equal distribution of benign and malignant tumors, while paranasal sinus tumors are usually malignant. Various benign, intermediate, and malignant tumor types are then classified and discussed in further detail over multiple pages, along with symptoms, diagnosis, and treatment approaches.

4. Oeteoma
Osteomas are common incidental finding in
frontal sinus x-ray
Majority are asymptomatic & do not grow
Surgery is done for symptomatic osteomas or
those that rapidly increase in size
Complete removal of tumor with its base
attachment is done by bicoronal osteoplastic
flap technique5/23/2020 4NEOPLASMS OF NASAL CAVITY & PNS

proliferation of fibrous tissue, resulting in
distortion & expansion of bone
