Slides prepared by highly experienced ENT teacher, Dr. Krishna Koirala from Nepal, for teaching undergraduate and postgraduate MBBS students in the field of otorhinolaryngology. A clear and concise explanation of the basic concepts in the subject matter concerned.
2. Defined as chronic inflammation of nose characterized
by progressive atrophy of nasal mucosa, including the
glands, turbinate bones and the nerve elements
supplying the nose
Characterized by formation of scanty viscid secretion &
greenish crusts which emit a foul odour (ozaena)
Removal of crusts reveals roomy nasal cavity
Types
Primary
Secondary
13. D/D for ozaena D/D for dry nose
1. Atrophic rhinitis 1. Atrophic rhinitis
2. Purulent sinusitis 2. Rhinitis sicca
3. Nasal foreign body 3. Radiotherapy
4. Rhinitis caseosa 4. Sjogren’s syndrome
5. Malignancy
14. Causes of Anosmia
1. Loss of olfactory neural elements
2. Thick secretion & crusts over olfactory area
3. Degeneration of secretary glands scanty mucus
for dissolving odoriferous materials
Causes of nasal obstruction
1. Blunting of sensory nerve endings
2. Crust formation
3. Lack of eddy current formation in roomy cavity
15. Pathology
• Accumulation of lymphocytes & plasma cells
• Metaplasia from ciliated columnar to squamous
epithelium
• Ciliary destruction & decrease in number & size of
nasal glands
• Bone resorption
• Type I: Endarteritis & periarteritis of terminal arterioles
Benefit from vasodilator effect of estrogen therapy
• Type II: Dilated capillaries worsened by estrogen
16. Specific Investigations
Saccharine test
ed nasal muco- ciliary clearance time
Serum iron & protein levels: malnutrition
Culture & sensitivity of nasal discharge
X-ray P.N.S. : maxillary sinusitis
17. C.T. Scan Nose and P.N.S.
Mucosal thickening
Resorption of ethmoid bulla
& uncinate process
Hypoplasia of maxillary
sinuses
Roomy nasal cavities
Erosion & bowing of lateral
nasal wall
Atrophy of turbinates
18. Chest X-ray: T.B., bronchiectasis, lung abscess
Serology for syphilis: V.D.R.L., T.P.H.A., T.P.I.
Sputum for AFB, Mantoux test: T.B.
Nasal smear study: leprosy
Complement fixation test & biopsy: Rhinoscleroma
21. Alkaline Nasal Douche
Sodium bicarbonate (28.4g) loosens nasal crusts
Sodium biborate (28.4g) Antiseptic
Sodium chloride (56.7g) makes soln isotonic
• Mixed in 280 ml of warm water to make the solution
• 6” long rubber tubing fitted in 20 ml plastic syringe
• Syringe nasal cavity while pt bends forward & keeps
saying K, K, K … to close nasopharyngeal isthmus
• Done twice daily till all crusts disappear
23. Young’s operation: Only 1 nostril closed
completely by raising 2 circumferential flaps
(inner mucosal & outer cutaneous) in nasal
vestibule & suturing them in midline
Modified Young’s operation done by similar
way but keeping a 3 mm opening on both
sides
Recanalisation done after 12-18 month with
a tri-radiate (Mercedes Benz) incision
30. Advantages of Modified Young
Progress of disease can be monitored with 2.7 mm
nasal endoscope
Glucose in glycerine drops can be instilled
Both nostrils can be operated at one sitting
Nasal breathing preserved
No complaints of de-nasal voice
Better cosmetic result
31. Lautenslager’s operation: Fracture & medial
displacement of lateral nasal wall
Wilson’s operation: submucosal injection of Teflon
paste
Antral mucosal transplantation into nasal cavity
through intranasal antrostomy
Vestibuloplasty: raising a lateral shelf from nasal
vestibular flap to cover the turbinates
