ANATOMY
Polyp usually arise from lateral wall of the middle meatus, middle turbinate or ethmoid, and hang down into the nasal cavity.
Polyp consists of a pedicle, a body and a fundus. Usually round, smooth, soft, translucent, yellow or pale
glistening structure attached to nasal mucosa with narrow stalk.
Occasionally cubical, or pavement in places.

ALLERGIC NASAL POLYPI
Multiple Ethmoidal polypi
SITES OF ORIGIN
Antrochoanal polyp filling the nasopharynx
04/11/23 17
HISTOLOGY
Microscopically covered with ciliated columnar epithelium with large amount of fluid i.e. transudate, in the substance of Polypus.
Very few glands and blood vessels. Round cell infiltration and Eosinophils. No nerves.
ALLERGIC NASAL POLYPI
04/11/23 18
PATHOPHYSIOLOGY
Hypersensitivity reaction; Type-I IgE mediated. Release of Histamine from mast cells and basophils
in the submucosa of nasal cavity. Vasodilation, smooth muscle contraction and
increased capillary permeability. Odema, Polyp formation.

Five theories: Bernouli Phenomenon- (Gravitational Pull) Polysacharide Changes- (Alteration in the ground
substance has been postulated but analysis shows no collagen changes).
Vasomotor Imbalance- (Sympathetic- Parasympathetic imbalance with parasympathetic dominance).
Infection- Rhinitis & Sinusitis play a role. Purulent Hyperplastic
Allergic- See next slide
ETIOLOGY
ALLERGIC NASAL POLYPI
Contd.
04/11/23 20
ETIOLOGY
Allergy: Allergy is implicated because of histologic picture of eosinophilia and association with asthma.
Nasal Allergy- an expression of pathologic hypersensitivity, mediated by antibody upon exposure to an antigen.
Two types of Antibodies: Humoral- associated with immediate reaction, e.g, Hay Fever, Urticaria, Somatic antibodies- associated with delayed
reaction, e.g, Tuberculosis, Allergic reaction to infection.

SYMPTOMS
Nasal Obstruction Thin profuse Nasal discharge Anosmia Headache/ loss of concentration Epiphora Conductive deafness Rhinolalia clausa - Dull, toneless speech due
to nasal blockage
ALLERGIC NASAL POLYPI

SIGNS:
Anterior Rhinoscopy: multiple grape like swellings(Polyps)
hanging from the roof. Smooth and shinny, covered with thin
discharge, non tender, can be moved with blunt nasal probe.
Posterior Rhinoscopy: Engorged posterior tips of the inferior
turbinates and septal turbinates.

INTRANASAL SIGNS

SIGNS
Frog-nose, due to broadening of nasal bridge, Typical faces of chronic mouth breather, Allergic shiners caused by dark circles under the eyes
due to venous stasis by engorged nasal membranes. Rabbit nose due to wrinkling of the end of the nose. Allergic Salute- due to repeated wiping of runny nose.

COMPLICATIONS
Nasal blockade Repeated infections
Infective rhinnitis Infective sinusitis– Bacterial/ Fungal
Epistaxis Anosmia Hyper telorism Eustachian tube dysfunction- with middle ear
effusion. Facial deformity– Frog nose (adults) Rabbit nose (children) Asthma.

LABORATORY FINDINGS
Periphiral Eosinophilia:3- 10 % eosinophils in the nasal secretion is diagnostic of allergic rhinitis.
Nasal secretion cytology reveals presence of eosinophils.
Elevated IgE serum levels seen in 50% patients. Allergic Skin testing, by methods like Prick test,
Scratch test and Intradermal test.

TREATMENT:ALLERGIC NASAL POLYPI
MANAGEMENT
Conservative Surgical
04/11/23 32
Avoidance of allergens/Irritants. Environmental control. Immunotherapy Intermittent use of anti-histamines, locally or per oral. Local decongestants, as drops or sprays. Topical steroid therapy- to avoid recurrence. Anti-biotic therapy, where indicated.
ALLERGIC NASAL POLYPI
CONSERVATIVE MANAGEMENT
04/11/23 33
TREATMENT:
Removal of polypi under local or general
anesthesia with non-cutting nasal polypus snare.
Recurrent cases- Intranasal ethmoidectomy Removal of cause- Allergy sinusitis, DNS.

SUMMARY
Bil. Nasal polyps usually originate from ethmoid sinuses and are sometimes associated with nasal allergy.
These polypi are usually multiple and nasal airway obstruction caused by them is occasionally the prime symptom forcing the patient for an E.N.T consultation.
Broadening of the nose could be a prominent feature in advanced cases. Hypertelorism and proptosis is often seen associated with them if left untreated.
Cases have been reported where nasal polypi have invaded the anterior cranial fossa.
ETHMOIDAL POLYPI
04/11/23 36
SUMMARY Aggressive, invasive and recurrent polyp formation
could not possibly have only allergic basis. It may be due to allergic and infective processes acting together including fungal infection.
Aspergillus is the most common organism responsible for the sinusitis and recurrent polypi.
Polyps with onset in childhood may be very aggressive and lead to splay the bones producing widened bridge. They are however nearly always associated with cystic fibrosis.

SURGICAL MANAGEMENT
Asymptomatic Small Polypi No active surgical intervention required Local steriods have a role.
Large symptomatic polypi Surgical options need to be considered.

ANAESTHESIA:
Local Anaesthesia Little bleeding Polypi shrink into the ethmoids –High recurrence
rate. General Anaesthesia
Cuffed peroral endotracheal tube Pharyngeal pack.
Better Clearance of polypi Excellent access to the ethmoids. More bleeding.

“To reduce the operative complications, surgeon must take care to keep his instruments below the cribriform plate, medial to the orbital periosteum and infront of the optic foramen”
