Abstract
Tumors of the nose and paranasal sinus are of two types benign
and malignant. Benign tumors are uncommon in comparison with
malignant growths.
The most common benign tumors (in decreasing order of
frequency) are osteoma, hemangioma, papilloma, and angiofibroma. The
two tumors of greatest interest are the inverted papilloma and the juvenile
nasopharyngeal angiofibroma.
The most common malignant tumors are squamous cell carcinoma,
adenocarcinoma, adenoid cyctic carcinoma, olfactory
esthisioneuroblastoma.
In contrast to many other areas in the head and neck, paranasal
sinus tumors are not characterized by an early presentation. The typical
delay in diagnosis is commonly cited as 8 months or more. This is
secondary to the fact that the early symptoms seen by primary care
physicians.
Complains such as nasal obstruction, rhinorrhea, and epistaxis
rarely receive.
