NASAL POLYP

NASAL POLYP

NASAL POLYP
A nasal polyp is an inflammatory condition that is associated with the lining of the paranasal sinuses and the nasal mucosa. Nasal polyps are actually movable grape-like overgrowths that emerge as a result of inflammation of the lining of the nasal lining that project into the centre of the nose. These overgrowths are soft, lack sensation and may go unnoticed for a long time. This condition is inclined to adults. However, when suspected in children below the age of ten, cystic fibrosis is ruled out.




Classification of nasal polyps

Nasal polyps are broadly classified into two depending on where they originate from.

1. Ethmoidal polyps

2. Antrochoanal polyps

Ethymoidal polyps originate from anterior ethymoidal region of the nasal cavity and exist in multiples while antrochoanal polyps, which occur in rare cases, are often unilateral and exist in singles. They originate from the maxillary sinuses.
The real cause of nasal polyps has remained a puzzle. However a number of entities have been associated with the condition. They include; Allergy, rhinosinusitis, cystic fibrosis, salicylate sensitivity, asthma, enzyme abnormality, autonomic imbalance, epithelial rapture, infection and nasal masocytosis.
Common symptoms of nasal polyps include; persistent stuffiness, decreased sense of smell, sleep disorders, general nasal obstruction, reduced quality of life, impaired sense of taste, facial pain, snoring and running rose. Nasal polyps contain more neutrophils , plasma cells and eosinophils as compared to the nasal mucosa.

In diagnosing nasal polyps, a close and careful examination of the nose should be carried out. In endoscopic examination, biopsy and culture of the produced discharge can be done to determine the cause of the condition. Nasal polyps can be treated by use of both surgical methods and use of steroids.
