Q

The predisposing factors of chronic rhinitis

A
  1. Persistence of nasal infection due to sinusitis, tonsillitis and adenoids.
  2. Chronic irritation from dust, smoke, cigarette smoking, snuff, etc.
  3. Nasal obstruction due to deviated nasal septum, synechia leading to persistence of discharge in the nose.
  4. Vasomotor rhinitis
  5. Endocrinal or metabolic factors, e.g. hypothyroidism, excessive intake of carbohydrates and lack of exercise.

Maximum changes are seen in the inferior turbinate.
It may be hypertrophied in its entirety or only at the anterior end, posterior end or along the inferior border giving it a mulberry appearance.

Q

Etiopathogenesis of COMPENSATORY HYPERTROPHIC RHINITIS

Q

ATROPHIC RHINITIS (OZAENA)

A

It is a chronic inflammation of nose characterized by atrophy of nasal mucosa and turbinate bones. The nasal cavities are roomy and full of foul-smelling crusts.

Q

Types of Atrophic rhinitis

A

primary and secondary

21
Q

Etiology of atropic rhinitis

A
  • hereditary factors
  • endocrinal disturbance
  • racial factors
  • nutritional deficiency
  • infective
  • Autoimmune
22
Q

How endocrine disturbance cause atrophic rhinitis

A

Disease usually starts at puberty, involves females more than males, the crusting and foetor associated with disease tends to cease after meno- pause

23
Q

Which races are more susceptible for atropic rhinitis

A

White and yellow races

24
Q

Which vitamin or nutrition deficiency causes atropic rhinitis

A

A
D
And iron

25
Q

Which infection causes atropic rhinitis

A

Klebsiella ozaenae, (Perez bacillus), diphtheroids, Proteus vulgaris, Escherichia coli, staphylococci and streptococci but they are all consid- ered to be secondary invaders responsible for foul smell rather than the primary causative organisms of the disease.

26
Q

Which agent trigger the autoimmune process of atropic rhinitis

A

Viral infection trigger antigenicity of nasal mucosa

27
Q

Pathology of atropic rhinitis

A

Ciliated columnar epithelium is lost and is replaced by stratified squamous type. There is atrophy of seromucinous glands, venous blood sinusoids and nerve elements. Arter- ies in the mucosa, periosteum and bone show obliterative endarteritis. The bone of turbinates undergoes resorption causing widening of nasal chambers. Paranasal sinuses are small due to their arrested development

28
Q

Clinical Features of atropic rhinitis

A
  • foul smell from the nose
  • merciful anosmia due to degenerative changes
  • nasal obstruction due to large crusts filling the nose
  • Epistaxis may occur when the crusts are removed.
29
Q

Examination of nose in atropic rhinitis reveals

A

Nasal cavity is Full of greenish or greyish black dry crusts covering the turbinates and septum.
When they are removed, nasal cavities appear roomy with atrophy of turbinates
Nasal turbinates may be reduced to mere ridges.
Nasal mucosa appears pale.
Septal perforation and dermatitis of nasal vestibule may be present. Nose may show a saddle deformity.

30
Q

What are the changes seen in pharynx and laryngeal mucosa in atropic rhinitis

A
  • pharyngeal mucosa which may appear dry and glazed with crusts
  • Similar changes may occur in the larynx with cough and hoarseness of voice (atrophic laryngitis).
31
Q

Hearing impairments in atropic rhinitis is due to

A

obstruction to eustachian tube and middle ear effusion

32
Q

How does paranasal sinus appear in atropic rhinitis

A

small and underdeveloped with thick walls.

They appear opaque on X-ray

33
Q

Medical Rx in primary atropic rhinitis

A
  • Nasal irrigation and removal of crusts
  • 25 % glucose in glycerine - inhibits the growth of proteolytic organisms
  • Local antibiotics -KemicetineTM antiozaena solution contains chloromycetin, oestradiol and vitamin D2 and may be found useful.
  • Oestradiol spray-increase vascularity of nasal mucosa and regeneration of seromucinous glands
  • Placental extract
  • Systemic use of streptomycin. 1 g/day for 10 days
  • Potassium iodide given by the mouth promotes and liquefies nasal secretion.
34
Q

Surgical methods for primary atropic rhinitis

A
  • Young’s operation
  • modified Young’s operation
  • Narrowing the nasal cavities
35
Q

Narrowing of nasal cavities for primary atropic rhinitis is done by

A

(i) Submucosal injection of teflon paste.
(ii) Insertion of fat, cartilage, bone or teflon strips under the mucoperiosteum of the floor and lateral wall of nose and the mucoperichondrium of the septum.
(iii) Section and medial displacement of lateral wall of nose.

36
Q

Secondary atropic rhinitis causes

A

syphilis, lupus, leprosy and rhinoscle- roma may cause destruction of the nasal structures leading to atrophic changes. Atrophic rhinitis can also result from long-standing purulent sinusitis, radiotherapy to nose or excessive surgical removal of turbinates.

37
Q

Unilateral atrophic rhinitis is caused by

A

Extreme deviation of nasal sep- tum may be accompanied by atrophic rhinitis on the wider side.

38
Q

RHINITIS SICCA is also called as

A

crust-forming disease

39
Q

RHINITIS SICCA is seen in people who work In

A

hot, dry and dusty surroundings, e.g. bakers, iron- and gold- smiths.

40
Q

RHINITIS SICCAis confined to which part of the nose

A

anterior third of nose particularly of the nasal septum

41
Q

Pathogenesis of RHINITIS SICCA

A

Here, the ciliated columnar epithelium undergoes squamous metaplasia with atrophy of seromucinous glands. Crusts form on the anterior part of septum and their removal causes ulceration and epistaxis, and may lead to septal perforation.

42
Q

Rx for Rhinitis sicca

A

correction of the occupational sur- roundings and application of bland ointment or one with an antibiotic and steroid to the affected part.

43
Q

Rhinitis caseosa affects mainly which gender

A

Males

44
Q

Presentation of rhinitis caseosa

A
  • unilateral, Nose is filled with offensive purulent discharge and cheesy material.
  • The disease possibly arises from chronic sinusitis with collection of inspissated cheesy material.
  • Sinus mucosa becomes granulomatous.
  • Bony walls of sinus may be destroyed, requiring differentiation from malignancy.
45
Q

Rx for rhinitis caseosa

A

Treatment is removal of debris and granulation tissue and free drainage of the affected sinus. Prognosis is good.

46
Q

Hypertrophic rhinitis changes are more marked in

A

turbinates
