Frequency-specific hearing results after surgery for chronic ear diseases.

Objectives: To analyze frequency-specific hearing results after surgery for chronic ear diseases while considering pathological findings and various surgical factors.

Methods: Patients who underwent surgical management of chronic otitis media were reviewed retrospectively (n=559). Using pure tone audiometry, air conduction (AC), bone conduction (BC), and air bone gap (ABG) change between pre- and post-operative tests were calculated for the frequencies of 250, 500, 1,000, 2,000, 3,000, 4,000 (AC and BC), and 6,000 Hz (AC).

Expression of HSP70 and Its Relation with Other Cytokines in Human Middle Ear Effusion.

Objectives: While other cytokines are known to be associated with otitis media with effusion (OME), the involvement of heat shock protein 70 (HSP70) in middle ear effusion (MEE) is unknown. This study was undertaken to investigate the possibility of there being a HSP70 expression in human MEE and to determine its potential role as a cytokine in OME.

Methods: The levels of HSP70, tumor necrosis factor-alpha and interleukin-1beta were measured by enzyme-linked immunosorbent assay in the effusion of different groups of OME patient following collection of the MEE using our new collection system.

Clinical experience of 71 cases of congenital middle ear cholesteatoma.

Conclusions: As congenital middle ear cholesteatoma (CMC) is a different disease entity from acquired cholesteatoma, early diagnosis is important for good treatment results. Preoperative computed tomography (CT) imaging is a useful modality for both evaluation of the extent of the disease and selection of appropriate surgical methods. Some modification should be considered based on the findings of the actual operative field for complete removal of CMC.

The appropriate medical management of methicillin-resistant Staphylococcus aureus in chronic suppurative otitis media.

Conclusion: Methicillin-resistant Staphylococcus aureus (MRSA) was the most prevalent species (28.1%) in the bacteriological study of 577 patients with chronic suppurative otitis media (CSOM). Frequent and appropriate aural cleansing and irrigation using diluted acetic acid or other solutions such as Burow's solution can be an effective method for the medical treatment of MRSA in CSOM.
