Earache (Otalgia): Or something else? Differential Diagnosis

Respiratory System (J00-J99)

  • Laryngitis (inflammation of the larynx).
  • Peritonsillar abscess (PTA) – spread of inflammation to connective tissue between tonsil (tonsils) and constrictor pharyngis muscle with subsequent abscessation (collection of pus); predictors of peritonsillar abscess: male sex; age 21-40 years and smoker [unilateral sore throat/severe pain, trismus (lockjaw), potty voice, and deviation of uvula (uvula of palate)]
  • Pharyngitis (pharyngitis) [infants and children.]
  • Tonsillitis (tonsillitis) [adolescents]
  • Tongue base inflammation

  • Erysipelas – acute skin infection caused by streptococci.
  • Parotitis epidemica (mumps or goat’s peter popularly known) [infants and children].
  • Pneumococcal infection – pneumococci most commonly cause pneumonia (pneumonia), but meningitis (meningitis) and otitis media (otitis media) are also among the infectious diseases caused by pneumococci
  • Tabes dorsalis – late symptoms of syphilis, which is manifested by neurological symptoms.

Mouth, esophagus (esophagus), stomach, and intestines (K00-K67; K90-K93).

  • Dental abscess (dental abscess)
  • Dentitio difficilis (difficult eruption of a wisdom tooth).
  • Sialolithiasis (salivary stones).
  • Salivary gland abscess – accumulation of pus in the area of the salivary glands.
  • Dental disease, unspecified

Musculoskeletal system and connective tissue (M00-M99).

  • Costen’s syndrome (otodental syndrome) – headache, earache caused by bite abnormalities or other dental and jaw problems.
  • Dysfunction of the temporomandibular joint
  • Cervical spine disorders, unspecified (e.g., cervical spondylosis).
  • Temporomandibular joint arthropathy – temporomandibular joint disorders, unspecified [adult].

Neoplasms – tumor diseases (C00-D48).

  • Acoustic neuroma (AKN) – benign (benign) tumor arising from the Schwanńs cells of the vestibular portion of the VIII. Cranial nerve, the auditory and vestibular nerves (vestibulocochlear nerve, acustic nerve; octaval nerve), and is located in the internal auditory canal (intrameatal), or in the cerebellopontine angle (extrameatal) in case of larger extension
  • Pharyngeal carcinomas [older adults]
  • Tumors of the ear and surrounding tissues [older adults].

Ears – mastoid process (H60-H95)

  • Cerumen obturans – obstruction of the ear canal by earwax (cerumen).
  • Ear canal eczema
  • Ear canal furuncle [older adults]
  • Mastoiditis (mastoid process inflammation)
  • Otitis externa (inflammation of the external ear): [adolescents; especially in summer] [adults].
    • Otitis externa circumscripta (circumscribed); usually Staphylococcus aureus (bacterium); symptoms: course severe, pulsating; possibly fever; secretion: if boil is closed: none; otherwise putride (“putrid”).
    • Otitis externa diffusa: usually Pseudmona aeruginosa; symptoms: course strong to moderate, tragus pressure pain; often no general symptoms, no fever; secretion: watery / odor: sweetish, bland.
    • Otitis externa mycotica (otomycosis; fungal): Aspergillus species; symptoms: course long; no general symptoms; secretion. friable.
  • Otitis media (inflammation of the middle ear) [infants and children.]
  • Tympanic effusion (synonym: seromucotympanum) – accumulation of fluid in the middle ear (tympanum).
  • Perichondritis (inflammation of the cartilaginous membrane).
  • Tubal catarrh – inflammation of the mucous membrane of the Eustachian tube.

Psyche – nervous system (F00-F99; G00-G99)

  • Psychogenic otalgia
  • Trigeminal, occipital, cervical neuralgianerve pain occurring in the area of the affected nerve [adult].
  • Zoster oticus – acute skin disease resulting from infection with varicella zoster virus that causes pain in the area of the facial nerves [older adults].

Injuries, poisoning, and other sequelae of external causes (S00-T98).

  • Barotrauma (“pressure injury”).
  • Foreign body in the external auditory canal [infants and children] [adolescents].
  • Carious molars [adults]
  • Skull base injury
  • Trauma (injuries with z.B. cotton swab) [teenagers].
  • Wisdom teeth [teenagers]
  • Tooth damage, jaw inflammation [older adults].
