Chronic sinusitis significantly impairs middle ear function, affecting Eustachian tube function and hearing. The severity of this hearing impairment increases with the extent and duration of sinusitis.

Area of Science:

  • Otolaryngology
  • Audiology
  • Medical Research

Context:

  • Chronic sinusitis is a prevalent condition affecting the paranasal sinuses.
  • Middle ear function is crucial for normal hearing and is susceptible to adjacent inflammation.
  • Understanding the impact of sinusitis on the middle ear is vital for comprehensive patient care.

Purpose:

  • To investigate the relationship between the extent and duration of chronic sinusitis and its effects on middle ear function.
  • To quantify the prevalence of middle ear dysfunction in patients with chronic sinusitis.
  • To determine if sinusitis severity correlates with the degree of middle ear impairment.

Summary:

  • Eustachian tube function was disturbed in 48.3% of patients, tympanograms were abnormal in 42.0%, and air hearing thresholds were elevated in 33.9%.

  • Significant differences in middle ear function were observed between anterior and pan-sinusitis (P < 0.01).
  • Middle ear function also differed significantly between sinusitis cases of less than 5 years and those exceeding 5 years (P < 0.05).

    • Impact:

    • Findings indicate that more extensive paranasal sinus disease and longer disease duration lead to more severe middle ear dysfunction.
    • This study highlights the detrimental effects of chronic sinusitis on auditory health.
    • Results underscore the importance of considering middle ear status in the management of chronic sinusitis.
