Recurrent attacks of acute tonsillitis
4-6 weeks following an attacks of peritonsillar abscess (Interval
tonsillectomy)
Huge tonsil causing obstructive sleep apnoea syndrome.

1.Approach
Glosso-pharyngeal neurectomy in glossopharyngeal
neuralgia
Elongated styloid process.
UPPP
2. Tonsillar cyst, Tonsillolith.
3. Foreign body – tonsil.
4. Suspected malignancy for biopsy.

43. Methods of Tonsillectomy
1. Dissection method
2. Laser (Light amplification by stimulated emission of
radiation )
Advantage: Less bleeding, less pain, less scarring,
quick healing.
Disadvantage: Cost of laser therapy is high.
.

44. 3. Cryosurgery
It utilizes freezing for excision of tissues with the help of
cryoprobe. Nitrous oxide cryoprobe can achieve a temperature of –
70c while liquefied nitrogen can cool upto –196c.
Mode of action:
1. Cell membrance ruptures due to the formation of intracellular ice
crystals.
2. Intracellular dehydration occurs due to ice crystallization.
3. Proteins become denatured.
4. Enzymatic inhibition follows destruction of cellular metabolism.
5. Local ischaemia and microthrombosis of blood vessels occur.
Advantage: Less bleeding, less pain
Dis advantage: Histopathology of the excised tissue is not
possible due to destruction of the tissue by
freezing.

45. 4 . Radiofrequency method
5 . Coblation Method
Advantage: Less bleeding, less pain, less scarring,
quick healing.
Disadvantage: Cost is high.

nasopharyngeal incompetence and nasal intonation.

49. PERITONSILLAR ABSCESS PERITONSILLAR ABSCESS
(QUINSY)(QUINSY)
It is a collection of pus in the peritonsillar It is a collection of pus in the peritonsillar
space which lies between the capsule of space which lies between the capsule of
tonsil and the superior constrictor muscletonsil and the superior constrictor muscle

51. AETIOLOGY
•Peritonsillar abscess usually follows acute
tonsillitis
•First, one of the tonsillar crypts, usually
the crypta magna, gets infected and
sealed off. It forms an intratonsillar
abscess which then bursts through the
tonsillar capsule to set up peritonsillitis
and then an abscess.
•Culture of pus
•Growth of strept. Pyogenes, staph.
Aureus or anaerobic organisms. More
often the growth is mixed, with both
aerobic and anaerobic organisms.

52. CLINICAL FEATURES
•Peritonsillar abscess mostly affects adults
and rarely the children though acute
tonsillitis is more common in children
•General
•Fever (up to 104◦F) chills and rigors,
general malaise body aches headache
nausea and constipation
•Local
•Severe pain in throat
•Odynophagia
•Muffled and thich speech often called “hot
potato voice”

53. •Foul breath due to sepsis in the oral cavity
•Ipsilateral earache. This is referred pain via CN
IX which supplies both the tonsil and the ear.
•Trismus due to spasm of pterygoid muscles
•EXAMINATION
•The tonsil, pillars and soft on the involved side
are congested and swollen
•Uvula is swollen and oedematous and pushed to
the oposite side
•Bulge of the soft palate and anterior pillar
•Cervical lymphadenopathy is commonly seen
•Jugulodigastric lymph nodes
•Torticollis, patient keeps the neck tilted to the
side of abscess.

54. TREATMENT
•Hospitalisation
•Intravenous fluids to combat dehydration
•Antibiotics
•Analgesics like paracetamol
•Oral hygiene
•Incision and drainage of abscess. A
peritonsillar abscess is opened at the
point of maximum bulge above the upper
pole of tonsil or just lateral to the point of
junction of anterior pillar with a line drawn
through the base of uvula or midway
between base of uvula and 3rd molar.

55. •Interval tonsillectomy. Tonsils are
removed four to six weeks following an
attack of quinsy
•Abscess or hot tonsillectomy. Some
people prefer to do “hot” tonsillectomy
instead of incision and drainage. Abscess
tonsillectomy has the risk of rupture of the
abscess during anesthesia, and excessive
bleeding at the time of operation.

56. Complication
•Parapharyngeal abscess
•Oedema of larynx. Tracheostomy may be
required
•Septicaemia other complications like
endocarditis, nephritis, brain abscess may
occur.
•Pneumonitis or lung abscess. Due to
aspiration of pus, if spontaneous rupture
of abscess takes place
•Jugular vein thrombosis
•Spontaneous haemorrhage from carotid
artery or jugular vein
