This document summarizes various types of rhinitis including viral, bacterial, allergic, and non-allergic rhinitis. It describes the causes, symptoms, treatments, and complications of common cold, influenza, chronic non-specific rhinitis, allergic rhinitis, vasomotor rhinitis, and other less common types. Key points covered include the viral and bacterial causes of common cold, symptoms of allergic rhinitis like sneezing and nasal obstruction, and treatments for different rhinitis types including antihistamines, corticosteroids, immunotherapy, and surgery in some cases.

1. Manisha Mistry

2.  Acute Rhinitis can be –
•Viral
•Bacterial
•Irritative type

3. 1) Common cold
(Coryza)



Aetiology : Several viruses (adeno virus,
picorna virus and its sub-groups sucha s
rhinovirus, coxsackie, and ECHO) Clinical
features : Nasal stuffness, rhnorrhoea,
sneezing, low grade fever, secondary
bacterial invasion may occur.
Treatment : Bed rest, Plenty of fluids,
Anthihistaminics, Nasal decongestants,
Analgesics, Antibiotics,when secondary
infection supervenes.

4. Complications :
 Sinusitis, pharyngitis,tonsillitis,
bronchitis, pneumonia and otitis
media.
Influenzal rhinitis - Influenza
viruses A, B or C.
c/f are similar to common cold
Rhinitis associated with
exanthemas. Measles, rubella,
chickenpox.
precede exanthemas by 2-3 days

5.  Diphtheritic rhinitis :

• Primary
• Secondary to faucial diphtheria
• May occur in acute or chronic form
• Greyish membrane is seen covering the
inferior turbinate and the floor of nose;
membrane is tenacious and its removal causes
bleeding
Treatment : Isolation of the patient,
systemic penicillin and diphtheria
antitoxin.

6.  Chronic non-specific inflammations of
nose include :
1. Chronic simple rhinitis
2. Hypertrophic rhinitis
3. Atrophic rhinitis
4. Rhinitis sicca
5. Rhinitis caseosa.

7.  Aetiology : Predisposingfactors
a. Persistence of nasal infection due to sinusitis,
tonsillitis, and adenoids.
b. Chronic irritation from dust, smoke,cigarette
smoking, snuff.
c. Nasal obstruction.
d. Vasomotor rhinitis
e. Endocrinal or metabolic factors, e.g.
hypothyroidism.
a. Pathology : Hyperaemia and oedema of
mucous membrane, Hypertrophy of
seromucinous glands, increase in goblet
cells.

8.  Clinical features :
a. Nasal obstruction
b. Nasal discharge. It may be mucoid or
mucopurulent. Postnasal drip.
c. Headache
d. Swollen turbinates – They pit on pressure,
shrink with application of vasoconstrictor
drops (this differentiates the condition from
hypertrophic rhinitis).
e. Post-nasal discharge. Mucoid or
mucopurulent discharge.

9.  Treatment :
a. Treat the predisposing factor.
b. Nasal irrigations with alkaline solution.
c. Nasal decongestants.
d. Antibiotics help to clear nasal infection.

10.  Characterized by thickening of mucosa,
submucosa, seromucinous glands,
periosteum and bone.
Aetiology :
 Recurrent nasal infections
 Chronic sinusitis
 Chronic irritation of nasal mucosa.

11. Symptom
s :
 Nasal obstruction




Nasal discharge : thick
and sticky.
Headache
Heaviness of head
Transient anosmia.
Signs :
 Hypertrophy of



turbinates
Turbinal
mucosa is
thick, does not
pit on pressure,
little
shrinkage with
vasoconstrictor
drugs due to
underlying
fibrosis.
Maximum
changes in the
inferior turbiante.

12. Treatment :
 Discover the cause and remove it.
 Reduction in size of turbinates by
a. Liner cauterisation
b. Submucosal diathermy
c. Cryosurgeryof turbinates
d. Partial or total turbinectomy
e. Submucous resection of turbinates bone.
f.
Laser
s

13. Compensatory
hypertrophic rhinitis
• In cases of marked deviation of
septum to one side.
• Roomier side of the nose shows
hypertrophy of inferior and middle
turbinates.
• To reduce the wide space to
overcome the ill effects of drying
and crusting.

14.  Chronic inflammation of
nose
characterized by atrophy of nasal mucosa
and turbinate bones.
Primary atrophic rhinitis :
 Aetiology : Exact cause is not known,
Various theories regarding its causation
are:
a. Hereditary factors
b. Endocrinal disturbances : Starts puberty,
involves females more than males, tends to
cease after menopause.

15. c. Racial factors – White.
d. Nutritional deficiency : Deficiency of
vitamin A, D or iron.
e. Infective : Klebsiella ozaenae, (Perez
bacillus), diphtheroids, P.vulgaris, Esch.
Coli, Staphylococci and Streptococci but
they are all considered to be secondary
invaders.
f. Autoimmune process : The body reacts by
a destructive process to the antigens
released from the nasal mucosa.

16. Pathology :
 Ciliated columnar epithelium is
replaced by stratified squamous type.
 Atrophy of seromucinous glands,
venous sinusoids and nerve elements.
 Obliterative endarteritis.
 The bone of turbinates undergoes
resorption.
 Paranasal sinuses are small.

17.  Type 1: charecterised by endarteritis and
periarteritis of terminal arterioles
-result of chronic infection
- benefits from vasodilator effect of
oestrogen therapy
 Type 2: vasodilatation of capillaries
- which might be made worse by
oestrogen therapy

18. Clinical
features :
 Commonly seen in females and starts around









puberty.
Foul smell from the nose.
Marked anosmia (merciful anosmia)
Nasal obstruction
Epistaxis when the crusts are removed.
Nasal cavity full of greenish or greyish black dry
crusts.
Nasal cavities appear roomy.
Nasal mucosa appear pale.
Septal perforation and dermatitis of nasal vestibule.
Nose shows saddle deformity.

19. Prognosis :
 Disease persists for years
Treatment :
1. Medical :
a. Nasal irrigation and removal of crusts.
b. 25% glucose in glycerine. – Inhibits the growth
of proteolytic organisms which are responsible
for foul smell.
c. Local antibiotics – KemicetineTMantiozaena
solution contains chloromycetin, oestradiol and
vitamin D2.

20. d. Oestradiol spray – increase vascularity of
nasal mucosa and regeneration of
seromucinous glands.
e. Placental extract injected submucosally.
f. Systemic use of streptomycin – reducing
crusting and odour. Effective against
Klebsiella organisms.
g. Potassium iodide by mouth promotes and
liquefies nasal secretion.

21. 2.
Surgica
l :
a. Young’s operation – Both the nostrils are closed
completely just within the nasal vestibule by raising
flaps. They are opened after 6 months or later.
Modified young’s operation - Aims to partially close
the nostrils.
a. Narrowing the nasal cavities. Among the
techniques followed, some are :



Submucosal injection to teflon paste.
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.
Section and medial displacement of lateral wall of
nose.

22. SECONDARY ATROPHIC RHINITIS :
 Specific infections like syphilis, lupus,
leprosy and rhinoscleroma.
 Longstanding purulent sinusitis,
radiotherapy or nose or excessive
surgical removal of turbinates.
UNILATERAL ATROPHIC RHINITIS :
 Extreme deviation of nasal septum.
 Atrophic rhinitis on the wider side.

23. Crust-forming disease





Seen in patients who work in hot, dry and
dusty surroundings.
Confined to the anterior third of nose.
The ciliated columnar epithelium undergoes
squamous metaplasia.
Atrophy of seromucinous glands (Crusts,
epistaxis, septal perforation).
Treatment :


Bland ointment or an antibiotic and steroid.
Nasal douche.

24. 


Unilateral and mostly affecting males.
Nose is filled with offensive purulent
discharge and cheesy material.
Sinus mucosa becomes granulomatous.Bony
walls of sinus may be destroyed.
Treatment :


Removal of debris and granulation tissue
Free drainage of the affected sinus.

25. ALLERGIC RHINITIS

26. 

IgE – mediated immunologic response to
nasal mucosa to air-borne allergens. Two
clinical types
1. Seasonal. Symptoms appear in or around a
particular season.
2. Perennial. Symptoms are present throughout
the year

27. AETIOLOGY :
 Inhalant allergens – Pollen from the
trees and grasses, mold spores, house
dust, debris from insects or house mite
are common offenders.
 Genetic predisposition

28. Mast cell
Sensitized
Antigen
Release of mediators
Performed
• Histamine
• ECF – A
• NCF – A
• Heparin
•Others
Newly synthesized
• Prostaglandins e.g. PGD2
• Leukotrienes e.g. SRS-A
• PAG
• Thromboxane A
• TNFa

29.  Clinically allergic response occurs in 2
phases :
1. Acute or early phase : Within 5-30 min,
sneeing, rhinorrhoea nasal blockagte
and/or bronchospasm. Due to release of
vasoactive amines like histamine.
2. Late or delayed phase : 2-8 hours after
exposure to allergen without additional
exposure. Due to infiltration of inflammatory
cells eosinophils, neutrophils, basophil,
monocytes and CD4+ T cells at the site of
antigen deposition.

30. 


No age or sex predilection
Symptoms of seasonal nasal allergy.
Paroxysmal sneezing, 10-20 sneezes at a



time, nasal obstruction, waterynasal
discharge and itching in the nose.
Symptoms of perennial allergy.
Frequent colds, persistently stuffy nose,loss
of sense of smell due to mucosal oedema,
postnasal drip, chronic cough.
Signs of allergy may be seen in the nose,
eyes, pharynx or larynx.

31. Nasal signs :
• Transverse nasal crease
• Allergic salute
• Pale and oedematous nasal mucosa
• Thin, watery or mucoid discharge
Diagnosis :
• Detailed history and physical examination.

32. Investigations :
1. Total and differential count. Peripheral
eosinophilia.
2. Nasal smear shows large number of
eosinophils.
3. Skin tests. Prick, scratch and intradermal
tests.
4. Radioallergosorbent test (RAST). Measures
specific IgE antibody concentration in the
patient’s serum.
5. Nasal provocation test.

33. Complications :
1. Recurrent sinusitis.
2. Nasal polyp
3. Serous otitis media
4. Bronchial asthma.

34. Treatment :
1. Avoidance of allergen.
2. Treatment with drugs.
a. Antihistaminics
b. Corticosteorids
Oral corticosteorids
Use should be limited to acute episodes
Several systemic side effects
Topical steroids such as beclomethasone
dipropionate, budesonide, flunisolide acetate,
fluticasone are used as aerosols, very effective
in the control of symptoms.
Fewer systemic side effects.

35. c. Sodium
chromoglycate
Stabilizes the mast cells and prevents them
from degraulation.
2% solution for nasal drops or spray or as an
aerosol powder.
3. Immunotherapy
Allergen is given in gradually increasing
doses till the maintenance dose is reached.
Immunotherapy suppresses the formation of
IgE.

36.  Non-allergic rhinitis but clinically
simulating nasal allergy.
 Condition usually persists throughout
the year.

37. Pathogenesis :
 Parasympathetic stimulation causes
vasodilation and engorgement. Over activity


of parasympathetic system also causes
excessive secretion from the nasal glands.
Autonomic nervous system is under the
control of hypothalamus therefore emotions
play a great role in vasomotor rhinitis.
Nasal mucosa is also hyper-reactive and
responds to several non-specific stimuli e.g.
change in temperature, humidity.

38. Symptoms :
 Paroxysmal sneezing. In the morning.
Excessive rhinorrhoea. Profuse and watery.
Nasal obstruction


 Postnasal drip.
Signs
:
 Nasal mucosa over the turbinates is
generally congested and hypertrophic.
Complications :
 Nasal polypi, hypertrophic rhinitis and
sinusitis.

39. TREATMENT :
Medical :
1. Avoidance of physical factors which
provoke symptoms.
2. Antihistaminics and oral nasal
decongestants.
3. Topical steroids.
4. Systemic steroids – for a short time in
very severe cases.
5. Psychological factors should be
removed.

40. Surgical :
1. Nasal obstruction can be relieved by
measures which reduce the size of
nasal turbinates.
2. Excessive rhinorrhoea, relived by
sectioning the parasympathetic
secretomotor fibres to nose (vidian
neurectomy).

41. Other forms of non-allergic rhinitis :
1. Drug-induced rhinitis : Several
antihypertensive drugs. Some
anticholinesterase drugs e.g. neostigmine.
Contraceptive pills because of oestrogens.
2. Rhinitis medicamentosa :Topical
decongestant nasal drops cause rebound
phenomenon. Their excessive usecauses
rhinitis. Treated by withdrawal of nasal
drops, short course of systemic steroid.

42. 3. Rhinitis of pregnancy : Due to hormonal
changes. Local measures such as limited
use of nasal drops.
4. Honeymoon rhinitis
5. Emotional rhinitis : due to several
emotional stimuli.
6. Rhinitis due to hypothyroidism :
Predominance of parasympathetic activity.
7. Non air-flow rhinitis : Seen in patientsof
laryngoectomy and tracheostomy.
