Nasal Polyps

Dr. Vishal Sharma

Nasal Polyp Hypertrophied, oedematous, prolapsed mucosa of nose & paranasal sinus. Properties of nasal polyp:

Gray in colour

Glistening

Smooth surface

Pedunculated

Insensitive to pain

Mobile

Does not bleed on probing

Antro-choanal Polyp

Clinical Presentation

Adolescent / child

Unilateral nasal obstruction

Unilateral nasal discharge

Differential diagnosis

Hypertrophied inferior turbinate

Blob of mucous

Inverted papilloma

Rhinosporiosis & rhinoscleroma

Angiofibroma

Meningocoele

Malignancy

Nasal mass

Oropharynx examination

Oropharynx examination

Posterior rhinoscopy

Examination of nasal mass

Inspection = side, size, number, color, surface, pedunculated or sessile, origin, attachment

Probing = consistency, sensitivity to touch, bleeding on touch, can be passed all around

Shrinkage with decongestant drops

Probe test Antrochoanal polyp Hypertrophied turbinate Insensitive to pain Sensitive Probe can be passed all around Mobile Cannot be passed Not mobile

Etiology & origin Etiology:

Infective maxillary sinusitis

Anomaly of maxillary sinus ostium Origin:

Arises from maxillary sinus mucosa & exits via its natural or accessory ostium

Why AC polyp goes back?

1. Maxillary ostium is directed posteriorly 2. Cilia beat posteriorly 3. Air current flows posteriorly 4. Nasal floor slopes posteriorly 5. Posterior nasal cavity is larger 6. Negative oropharynx pressure while swallowing

Investigations

Diagnostic Nasal Endoscopy

X-ray PNS (Waters view)

X-ray nasopharynx lateral view: presence of air b/w skull base & polyp

CT scan PNS (coronal cuts)

Diagnostic Nasal Endoscopy

Diagnostic Nasal Endoscopy

X-ray Paranasal Sinus

C.T. scan Paranasal Sinus

C.T. scan Paranasal Sinus

Treatment

Antibiotics (pre & post operatively)

F.E.S.S. (avulsion polypectomy with middle meatal antrostomy)

Caldwell – Luc operation (for recurrence)

How to prevent recurrence

Complete removal of all parts

Wide middle meatal antrostomy (widening of maxillary sinus ostium)

Post-operative antibiotics

Parts of Killian’s A.C. polyp

Antral: globular

Nasal: flattened transversely

Choanal: globular

Neck: present at maxillary ostium

Middle meatal antrostomy

Caldwell – Luc Operation

Ethmoid Polyp

Clinical Presentation Adult patient

Bilateral nasal obstruction

Bilateral watery nasal discharge

Excessive, paroxysmal sneezing

H/o previous nasal surgery

B/l nasal mass

Anterior rhinoscopy

Broadening of nasal bridge

Etiology of ethmoid polyp 1. Allergy 2. Allergy + Infection 3. Vasomotor imbalance 4. Bernoulli phenomenon 5. Poly-saccharide changes

Associated diseases 1. Aspirin intolerance + Bronchial asthma + Ethmoid polypi = Samter’s triad 2. Cystic fibrosis 3. Allergic fungal sinusitis 4. Kartagener’s syndrome (ciliary dyskinesia + situs invertus) 5. Young’s syndrome (hyperviscous mucous + azoospermia)

Investigations

Diagnostic Nasal Endoscopy (D.N.E.)

X-ray PNS (Rhese lateral oblique view)

C.T. scan P.N.S. (coronal cuts)

Tests for allergy

Diagnostic Nasal Endoscopy

Diagnostic Nasal Endoscopy

Diagnostic Nasal Endoscopy

CT scan Paranasal Sinus

Non-surgical Treatment Given for very small polyps

Avoid allergens

Oral antihistamines (1-3 months)

Corticosteroid nasal sprays (3-6 months)

Oral prednisolone (1 mg/kg/day for 2 weeks)

Pre-steroid vs. Post-steroid

Surgical Treatment 1. Intra-nasal avulsion polypectomy 2. Extra-nasal external ethmoidectomy 3. Trans-antral ethmoidectomy 4. Functional Endoscopic Sinus Surgery

Conventional

Micro-debrider

Laser

How to prevent recurrence 1. Complete removal of all polyps 2. Avoid allergens 3. Post-operative course of:

Oral antihistamines (1-3 months)

Corticosteroid nasal sprays (3-6 months)

Bilateral FESS cavities

Post FESS CT scan

dolescents &

c

hildren Etiology is infection

Ethmoid polyp

Adult Allergic Single Unilateral Multiple Bilateral Shape is tri-lobed (dumbbell) Grows backward Treatment is surgical Recurrence is uncommon Grape like Forward Medical + Surgical Common
