Acute and chronic inflammatory ENT disorders

Otitis externa

  • Inflammatory disorders of the external ear are common
  • Can be either an acute or chronic disorder
  • Often associated with generalised skin disorders
  • Common pathogens include staphylococcal species and pseudomonas aeruginosa
  • Fungi, candida and aspergillus may also be involved
  • The condition is often bilateral
  • Treatment is with topical antibiotics and steroids
  • Debris should be suctioned under direct vision
  • Systemic antibiotics are rarely required

Acute suppurative otitis media

  • Common in childhood
  • Due to infection of the middle ear
  • Commonest pathogens are Streptococci pneumoniae and Haemophilus influenzae
  • Presents with severe ear ache
  • Child is usually systemically unwell
  • Tympanic membrane is often red and bulging
  • Pain may be relieved by rupture of the tympanic membrane
  • Child requires oral antibiotics for 10 days

Complications

  • Chronic suppurative otitis media
  • Adhesive otitis media
  • Tympanosclerosis
  • Ossicular destruction
  • Acute mastoiditis
  • Intracranial complications

Chronic suppurative otitis media

  • Classified into two types
  • Tubotympanic associated with perforation of the pars tensa
  • Atticoantral associated with a retraction pocket of the pars flaccida

Tubotympanic CSOM

  • Usually follows acute otitis media or trauma
  • Results in chronic perforation of the tympanic membrane
  • Presents with an intermittently discharging ear
  • Associated with conductive hearing loss
  • Treatment is with antibiotics, steroids and suction
  • If conservative treatment fails a myringoplasty may be needed
  • Temporalis fascia is usually used as the graft material

Atticoantral CSOM

  • More dangerous condition than tubotympanic CSOM
  • Associated with cholesteatoma formation
  • Squamous epithelium proliferates in the attic of the middle ear
  • Expanding ball of skin causes a low-grade osteomyelitis
  • Presents with purulent aural discharge and conductive hearing loss
  • Complications include:
    • Vestibular symptoms
    • Facial nerve palsy
    • Meningitis
    • Intracranial abscess
  • Treatment is surgical and requires either:
    • Atticotomy
    • Modified radical mastoidectomy

Acute tonsillitis

  • Common condition
  • Approximately 60% cases are bacterial
  • Often due to Group A streptococci
  • Characterised by sore throat, fever, malaise
  • Cervical lymphadenopathy usually occurs
  • Tonsils are usually enlarged and coated with pus
  • Treatment is with simple analgesia and penicillin

Quinsy

  • A quinsy is a peritonsillar abscess
  • Causes severe tonsillar pain and trismus
  • Examination shows swelling of the soft palate above the involved tonsil
  • The uvula is usually displaced
  • Treatment is with intravenous antibiotics
  • Abscess can be aspirated or drained under local anaesthetic
  • Consider elective tonsillectomy

Indications for tonsillectomy

Absolute

  • Sleep apnoea
  • Suspected tonsillar malignancy

Relative

  • Recurrent tonsillitis
  • Chronic tonsillitis
  • Peritonsillar abscess (Quincy)
  • Diphtheria carriers
  • Systemic disease due to beta-haemolytic streptococcus

Acute paediatric stridor

Congenital

  • Laryngomalacia
  • Laryngeal web
  • Subglottic stenosis

Acquired

  • Angioneurotic oedema
  • Impacted foreign body
  • Epiglottitis
  • Laryngotracheobronchitis
  • Vocal cord palsy
  • Benign laryngeal papillomatosis

Acute epiglottitis

  • Occurs in both adults and children
  • In children it is a life-threatening disease
  • In young children symptoms can progress rapidly
  • Due to haemophilus influenzae infection
  • Presents with stridor and drooling
  • Patient may require intubation or tracheostomy
  • Insertion of spatula may precipitate complete airway obstruction
  • Also require humidified oxygen and antibiotics
