Ear Infection Acute Suppurative Otitis Media in Children

Acute Suppurative Otitis Media is most common in children of age between 3 to 7 years. Also can occur at any age. Direct bacterial or secondary to viral upper respiratory tract infections is the most common aetiological factors. It has some predisposing and risk factors which are described below. Otitis media is very common in children with the average toddler having two to three episodes a year. Common cold is usually followed by otitis media.

What is Otitis Media?

it is an inflammation of part or all of the mucosa of the middle ear cleft. Middle ear cleft comprises of Eustachian tube, Tympanic cavity, Attic, Mastoid antram, Mastoid aircells and Aditus.

Classification of Otitis Media:

It is two types. Acute and chronic.

A. Acute Otitis Media or Acute Suppurative Otitis Media

B. Chronic Otitis Media

  1. Chronic Non Suppurative Otitis Media/ Otitis Media with Effusion or Glue Ear.
  2. Chronic Suppurative Otitis Media with Cholesteatoma /Attico antral type.
  3. Chronic Suppurative Otitis Media without Cholesteatoma/ Tubo tympanic type.
  4. Chronic adhesive otitis media.
  5. Chronic Specific Otitis media.

Definition of Acute Suppurative Otitis Media:

Acute inflammation of mucoperiosteal lining of middle ear cleft by pyogenic organism following most commonly a viral upper respiratory tract infections.

Routes of infection

  • Via eustachian tube
  • Via external ear
  • Blood born
  • Submucosal extention

Predisposing factors

  1. Rhinitis
  2. Sinusitis
  3. Nasopharyngitis
  4. Pharyngitis
  5. Tonsillitis
  6. Adenoids
  7. Nasopharyngeal tumour
  8. Nasal pack
  9. Cleft palate

Aetiology- Bacteriology

  1. Haemolytic streptococcus
  2. Strept.pneumoniae
  3. Staph. Aureus
  4. H. influenzae

Pathology

  • Tubal occlusion
  • Engorgement and oedema of the middle ear cleft lining
  • Exudation follows
  • Bulging of the T.M
  • Rupture
  • Hyperaemic decalcification
  • Osteitis
  • Subperiosteal abscess

Clinical Features:

Phase-I
Acute tubal obstruction
Fullness in the ear
Deafness
Retraction of the T.M
Phase-II
A. Acute infection of tympanic cavity
B. Before perforation-

  • Deafness increases
  • Bubbling sound heard in the ear
  • Discomfort progresses
  • Earache
  • Constitutional disturbances
  • Malaise,Pyrexia, in children abdominal pain and diarrhoea

Otoscopy
Tympani Membrane: – dilatation of blood vessels around the handle of malleus and periphery of the membrane. This increases until whole membrane is red and lustreless. With gradual loss of land mark as is thickens and bulges.

Acute Suppurative Otitis Media tympanic membrane

After perforation

  • Otorrhoea
  • Relief of pain

Phase III

  1. Retention of pus in mastoid
  2. Pain develops in the mastoid region
  3. Tenderness over the mastoid area
  4. Oedema
  5. The posterosuperior wall of the deep meatus sags from oedema
  6. Constitutional disturbances increases.

Differential Diagnosis

  • Furuncle or defuse otitis externa
  • Herpetic lesions of ear
  • Referred otalgia

Sequelae:

  1. Complete resolution
  2. Chronic Suppurative Otitis Media
  3. Adhesive otitis media
  4. Tympano Sclerosis

Complications:

Extracranial

  • Chr.S.O.M.
  • Mastoiditis
  • Facial palsy
  • Otitis externa
  • Labyrinthitis
  • Recurrent ASOM
  • Spticaemia
  • Pyaemia

Intracranial

  • Pachy meningitis
  • Lepto meningitis
  • Sub dural abscess
  • Encephalitis
  • Brain abscess

Treatment of Acute Suppurative Otitis Media:

Bed rest in warm well humidified room.

Phase I

  • Antibiotic
  • Nasal decongestant
  • Antihistamine

Phase II –Preperforative

  • Antibiotic
  • Analgesic
  • Antihistamine
  • Nasal decongestant

Surgical:-Myringotomy & suction under Microscope

Post perporative stage

  • Antibiotic
  • Antihistamine
  • Nasal decongestant
  • Aural toileting
  • Topical antibiotic drop

Phase III:- Treatment of complications

Decongestant Nasal Drops: Ephedrine nose drops (1 % in adults and 0.5% in children) or oxymetazoline or xylometazoline should be used to relieve eustachian tube oedema and promo te ventilation of middle ear.
Ear toilet: If there is discharge in the ear, it is drymopped with sterile cotton buds and a wick moistened with antibiotic may be inserted.
Dry local heat: It helps to relieve pain. All cases of acute suppurative otitis media shou ld be carefully followed till drum membrane returns to its normal appearance and conductive deafness disappears
