Acute And Chronic Pharyngitis

1. 1
Acute Pharyngitis

2. 2
Acute Pharyngitis
Definition*:
acute inflammation of pharyngeal
mucosa and submucosa, mostly
invovled in pharyngeal lymphoid tissue.

3. 3
Etiology
1. Virus*
2. Bacteria*
3. Invironmental Factors*

4. 4
Pathology
Acute inflammation of the pharyngeal
mucosal tissue:
Blood vessels dilatation
Inflammatory cells infiltration
mucosal swelling*

5. 5
Clinical Appearances
◆ Symptoms
1. fever, headache
2 . pharyngeal driness and painess, pain when swallowing
◆ Examination
pharyngeal mucosal congestion, swelling, edema of uvula
and soft palate, enlargement of the lympoid nodules on the
posterior wall of the pharynx , and the glands on each side
of the neck are usually swollen and tender

6. 6
Diagnosis and Differential Diagnosis
◆ Diagnosis:
history, symptoms, signs (examinations).
◆ Differential Diagnosis:
acute infectious diseases (measles,
scarlet fever,etc.)

7. 7
Complications

◆
involved in adjacent organs: otitis media,
sinusitis , and acute respiratory inflammation.

◆
others: acute nephritis, rheumatic fever, and
septicemia, etc.

8. 8
Treatment

◆
Non general symptoms or light symptoms:
local treatment, such as gargle, lozenge, etc.
◆ severe general symptoms: rest in bed, more
drink, antivirus, antibiotics
◆ Chinese Medicine

9. 9
Chronic Pharyngitis

10. 10
Chronic Pharyngitis
Definition*:
diffuse inflammation of pharyngeal
mucosa and submucosa, and pharyngeal
lymphoid tissue.

11. 11
Etiology
1. Local Factors：
◆ repeat relapse of acute pharyngitis
◆ affected by adjacent organs ：nose, tonsils.
◆ bad irritants
2. General Factors：
◆ General chronic diseases: anemia, dyspepsia, lower
respiratory chronic diseases, cardiovascular diseases,
etc.
◆ allergic factors

12. 12
Pathology
● Chronic simple pharyngitis: chronic mucosal
congestion, gland hypertrophy, hypersecretion.
● Chronic hypertrophic pharyngitis: mucosal
congestion, pharyngeal lympoid tissue hypertrophy.
● Atrophic pharyngitis and pharyngitis sicca: seldom
seen, etiology is unknown, hyposecretion, mucosa is
thin.

13. 13
Clinical Appearances
◆Symptoms
the description given of the symptoms varies
greatly with individuals, no general symptoms,
simple sore throat, a pricking or irritation as of a
foreign body, or an accumulation of mucus
causing a constant necessity to swallow.

14. 14
Clinical Appearances

◆
Examination
Chronic simple pharyngitis: mucosal congestion, vessels dilitation,
scatted lympoid follicles in pharyngeal posterior wall.
Chronic hypertrophic pharyngitis: mucosa menbrane is thickened
and reddened, a degree of edema of uvula may be found,
increase in size of lympoid islands in the mucosa of pharyngeal
posterior wall.
Atrophic pharyngitis and pharyngitis sicca: mucosa menbrane is
thin and pale colour, mucosa is driness, often attached thick
secretion.

Diagnosis

16. 16
Treatment
1. Etiologic therapy: eliminate anything which tends
to prolong the inflammation, altering the patient’s
habits ( food,tobacco, alcohol,etc.) , excises.
2. Local therapy: soothing gargle ,Chinese
Medicines.
3. Target therapy:
hypertropic type of diseases---cautery or
diathermy or laser

17. 17
Treatment Efficiency
The therapy is intractable and unsatisfactory
because of a high tendency to recurrence
and relapse.
