nerve supply of ear
Nerve Supply of Ear
  • Richly innervated
  • Multiple cranial & spinal nerves
  • Shared nerve supply with other head & neck sites
  • Inner ear has no sensory supply
details of nerves
Details of nerves

Most of the external ear

  • Great auricular nerve (cervical plexus C 2,3)
  • Auriculo temporal nerve (branch of Vc)

Small contributions from

  • Auricular branch of X nerve
  • Somatosensory branch of VII nerve

Middle ear supply

  • Tympanic branch of IX nerve

otalgia is ear pain
Otalgia is ear pain
  • 2 types
  • Primary otalgia

Pain that arises from a pathology within the ear (external , middle)

  • Referred otalgia

Pain that originates from outside the ear

primary otalgia
Primary otalgia
  • Common causes
  • Infections of pinna
  • external auditory canal (boil)
  • middle ear / mastoid (otitis media, mastoiditis)
  • Neoplasms of external & middle ear
referred pain
Referred Pain
  • Pain felt at a site different from the location of the injured or diseased part of the body
  • Nerve signals from several areas of the body may "feed" the same nerve pathway leading to the spinal cord and brain
  • EXAMPLES
  • Pain of coronary artery insufficiency
  • Gall bladder pain
  • Appendix
  • Liver
why referred otalgia occurs
Why referred otalgia occurs ?
  • Irritation of the large array of nerves

their distant branches

Cause perception of pain within the ear

common causes of referred otalgia
Common Causes of Referred Otalgia
  • Dental sources

Impacted tooth (last molar, upper)

Dental caries

Periodontal infection

Ill fitting dentures

pharyngeal causes
Pharyngeal causes
  • Acute tonsillitis
  • Peritonsillar abscess
  • Malignant tumours – Most important

Pharynx

Larynx

Oral cavity

neuralgias
Neuralgias
  • Clinical examination (ENT & neurological) must be normal
  • Trigeminal neuralgia –

unilateral facial pain

  • Glossopharyngeal neuralgia

unilateral pharyngeal pain
