A novel blow oxygen therapy significantly shortens treatment for glue ear (otitis media with effusion) and reduces dry ear time after mastoidectomy compared to traditional methods.

Area of Science:

  • Otolaryngology
  • Medical Technology
  • Surgical Innovation

Background:

  • Glue ear (otitis media with effusion) is a common condition requiring effective treatment.
  • Post-mastoidectomy otitis media can lead to prolonged dry ear times.
  • Current treatments for these conditions have variable efficacy and duration.

Purpose of the Study:

  • To evaluate a new blow oxygen method for treating glue ear.
  • To assess the efficacy of this method in reducing dry ear time following mastoidectomy.
  • To compare the blow oxygen method with standard tube insertion for glue ear treatment.

Main Methods:

  • The blow oxygen method was applied trans-externally via the ear canal after myringotomy and grommet insertion in 28 ears with glue ear.
  • A control group of 20 ears received only tube insertion.

  • The method's effectiveness on dry ear time post-mastoidectomy was also evaluated.

    • Main Results:

    • Treatment duration for glue ear was significantly shorter in the blow oxygen group (1.20 days) versus the control group (3.50 days).
    • Dry ear time after mastoidectomy was reduced to 3.92 weeks with blow oxygen therapy, compared to 5.82 weeks in the control group.
    • Statistical analysis confirmed significant differences between the groups for both outcomes.

    Conclusions:

    • The blow oxygen method presents a highly effective treatment for glue ear.
    • This innovative approach significantly shortens the time required for ears to become dry after mastoidectomy.
    • The blow oxygen method offers a promising advancement in otological treatments.
