1 Nasal polyp

2

3 Def: Sagging down of oedematous and hypertrophied mucosa of the nose and PNS. It is composed of loose fibro-oedematous tissue and surface is usually lined by ciliated columnar epithelium.

4 Types: Antrochoanal polyp Ethmoidal polyp

5 Antrochoanal polyp

6 Aetiology Mainly infection

7 Pathology Due to prolonged infection in the maxillary antrum
Accumulation of the exudate in the submucosa Antral mucosal swelling is aggravated by the traction of exudate Mucosal swelling interfere with lymphatic flow. Ultimately formation of antral polyp It goes through the ostium to nose and nasopharynx

8 Histopathology

9 Age: Common in children and young adult

10 Clinical features Symptoms: Nasal obstruction Nasal discharge Headache
Hyposmia

11

12 Signs Purulent or mucopurulent discharge Anterior rhinoscopy: Pale, smooth surface, insensitive to touch, soft, arising from the lateral wall of the nose and directed posteriorly Posterior rhinoscopy: Polyp in the posterior choana

13 Investigation X-ray PNS OM view X-ray nasopharynx L/V
Haziness in affected maxillary antrum and nasal cavity. X-ray nasopharynx L/V Soft tissue mass in nasopharynx, above and behind- air column present.

16 Treatment If facility available: ESS (Endoscopic sinus surgery)
If facility of ESS is not available: Before 15 years of age: Polypectomy+ AWO under GA After 15 years of age: Cald well-Luc operation under GA

17 Ethmoidal polyp

18 It arises from the ethmoidal air cells and directed downwards and forwards to the anterior nares

19

20 Aetiology Mainly allergic

21 Pathology Allergy- prolonged oedema of mucosa and submucosa
Accumulation of intracellular serous fluid and shows oedematous hypertrophy Mucosal swelling aggravated by the traction of discharge Interference of lymphatic flow Gravity and narrowness of the meatus promote downward extension and formation of polyp

22 Age: Common in middle age and elderly

23 Clinical features Symptoms: Nasal obstruction Nasal discharge Sneezing
Anosmia Headache

24 Signs Clear or Purulent/ mucopurulent discharge Anterior rhinoscopy: Multiple pale, pedunculated, movable soft tissue mass, usually bilateral, insensitive to touch, soft in consistency, coming from ethmoidal region 3. Broadening of nasal bridge ( frog-face deformity)- Long standing case

25 Investigations Pus for CS
X-ray PNS OM view: Haziness maxillary antrum (bilateral), Ethmoidal region hazy Nasal endoscopy CT scan

30 Treatment Conservative Antihistamine Local decongestant
Topical steroid

31 Surgical: 1. FESS 2. Polypectomy 3. Ethmoidectomy Intranasal External

32 Antrochoanal polyp Ethmoidal polyp Age Children & young adult Middle age & elderly Origin Maxillary antrum Ethmoidal air cell Aetiology Mainly infection Manly allergic Number Usually single Usually multiple Direction Downward & backward to posterior choana Downward &forward toanterior nares Usually unilateral Usually bilateral Nasal obstruction During expiratory phase During inspiratory phase
