Chronic middle ear inflammation, including cholesteatoma, significantly impairs taste function on the tongue, often without patients noticing. This study highlights the connection between ear health and gustatory senses.

Area of Science:

  • Otolaryngology
  • Neuroscience
  • Sensory Science

Background:

  • Previous research extensively documented gustatory function changes post-ear surgery.
  • The impact of chronic middle ear inflammation on taste perception remained largely unexplored.

Purpose of the Study:

  • To investigate the influence of chronic middle ear inflammation on taste function.
  • To assess taste alterations in patients with cholesteatoma or chronic otitis media.

Main Methods:

  • Prospective study design.
  • Quantitative gustatory tests administered to 46 patients (25 cholesteatoma, 21 chronic otitis media).
  • Patients had no prior surgical history.

Main Results:

  • Significantly reduced taste function observed on the anterior two-thirds of the tongue ipsilateral to the inflammation.

  • Impairment was consistent across diagnoses (cholesteatoma, chronic otitis media).
  • A trend indicated greater taste impairment with increased inflammation severity.
  • Conclusions:

    • Chronic middle ear diseases demonstrably alter taste function.
    • Many taste alterations associated with these conditions are subclinical and unnoticed by patients.
