Neoplasms of nasal cavity and paranasal sinuses
Neoplasms of Nose and Paranasal Sinuses Very rare 3% Delay in diagnosis due to similarity to benign conditions Nasal cavity ½ benign ½ malignant Paranasal Sinuses Malignant
Neoplasms of Nose and Paranasal Sinuses Multimodality treatment Orbital Preservation Minimally invasive surgical techniques
Neoplasms of nasal cavity Both benign and malignant tumours of the nasal cavity are uncommon. Very often their separation from tumours of paranasal sinuses is difficult except in early stages. In addition to primary tumours, nasal cavity can be invaded by growths from paranasal sinuses, neopharynx, cranial or buccal cavity
Neoplasms of nasal cavity Benign lesions are usually smooth, localised and covered with mucous membrane. Malignant ones are usually fiable, have a granular surface and tend to bleed easily
Benign Lesions Squamous papilloma Inverted papilloma Pleomorphic adenoma Schwannoma and meningioma Haemangioma Chondroma Angiofibroma Intranasal meningoencephalocele Gliomas Nasal dermoid
Papilloma Vestibular papillomas Schneiderian papillomas derived from schneiderian mucosa (squamous) Fungiform: 50%, nasal septum Cylindrical: 3%, lateral wall/sinuses Inverted: 47%, lateral wall
Benign neoplasms 1. Squamous papilloma. Verrucous lesions similar to skin warts can arise from the nasal vestibule or lower part of nasal septum. They may be single or multiple, pedunculated or sessile. Treatment is local excision with cauterisation of the base to prevent recurrence. They can also be treated by cryosurgery or laser
