    Positive middle ear pressure, indicated by tympanometry, is uncommon but linked to ear pain and throat inflammation. This finding is crucial for infant screenings and understanding middle ear infections.

    Area of Science:

    • Otolaryngology
    • Medical Diagnostics

    Background:

    • Positive middle ear pressure (PMEP) is infrequently documented in medical literature.
    • Tympanometry is a key diagnostic tool for assessing middle ear function.

    Purpose of the Study:

    • To investigate the incidence and clinical implications of PMEP.
    • To review associated symptoms and pathological findings in patients with PMEP.

    Main Methods:

    • Analysis of clinical, otoscopic, audiologic, and pathological data from 13 patients (16 ears) with PMEP exceeding +49 mm H2O.
    • Review of symptoms including otalgia, fullness, and pharyngitis.

    Main Results:

    • Acute middle ear pathology was confirmed in 13 ears.
    • Middle ear effusion was noted in 5 of 6 ears undergoing myringotomy.

  • Common symptoms included otalgia, ear fullness, and pharyngitis.

    • Conclusions:

    • PMEP has significant clinical implications, especially in non-medical screening settings and infant examinations.
    • Understanding PMEP is vital for evaluating the pathogenesis of otitis media.
