Hubungan jenis bakteri aerob dengan risiko tuli sensorineural penderita otitis media supuratif kronis

Background: Sensorineural hearing loss (SNHL) as sequelae of chronic supurative otitis media(CSOM) is still debatable. Previous researches had shown the role of bacterial toxin upon the roundwindow membrane which could induce SNHL. Purpose: To find the relationship between the kind ofaerobic bacteria with the risk of SNHL in CSOM patients. Method: This study used cross sectional 2005 toDecember 31design and involved 45 CSOM patients with SNHL in Dr. Saiful Anwar hospital from January 1, 2010. The specimen for microbacterial cultures and sensitivity tests were taken from themastoid antrum during mastoidectomy. Statistical analysis employed Spearman correlation test, t-test,and Mann Whitney. Result: The mean values of bone conduction threshold (BCT) in all of CSOM cases,especially in dangerous type CSOM patients, with bacteria culture showed Staphylococcus aureus werehigher than others bacteria (p 0,05). Kesimpulan: Terdapat hubungan bermaknaantara jenis bakteri aerob dengan rerata ambang hantaran tulang penderita OMSK, khususnya OMSKtipe maligna.   Kata kunci: OMSK, tuli sensorineural, bakteri aerob, toksin, ambang hantaran tulang
