Nasal polyp

Nasal polypBy d.g

There are two types of nasal polypAntrochoanalEthmoidal

Antrochoanal typeIt arises from the maxillary antrum and grows backwards in to nose towards the choana and nasal cavity riches the nasopharynx .

Ethmoidal They are multiple bilateral and arises from numerous ethmoidal sinuses.It is very commonly found

Etiology ANTROCHOANAL POLYP-Exact cause is not known.AGE: usually it occurs in children and young adults.NUMBER: usually it is single.INFECTION and ALLERGY may result in ANTROCHOANAl POLYP.

ETHMOIDAL POLYPAGE; ethmoidal polyps occurs at any age SEX: both sexes are equally affected PREDISPOSING FACTOTRS:Allergy Vasomotor Infection Mixed infection

Polysaccharide changes Bernouillis phenomenon: when air passes through a narrow area in the nose negativre pressure develops in the viscinity in the paranasal sinuses leading to increased formation of tissue fluids this may encourage polyp formation.

Asthma can be associated with ethmoidal polyp.Aspirin sensitivity

Pathology Antrochoanal polypMacroscopic :antral part : arise from maxillary antrum.Mucosa:oedamatousNasal part: arise from hiatus semilunaris in nose and reaches the choana

Pharyngeal part :enters the naso pharynx through choana.ETHMOIDAL POLYP:Arised from mucosa ethmoidal sinuses and hang down in the nasal cavity .

Microscopic Mucous membrane: metaplastiv changes.Polyp: ulcerated or protrudedSubmucoasal tissue:oedamtoius.Cellular infiltration occursPolyp is avascular and pain lessBlood vessels and nerves supply scanty
