Objective: Microbial infection plays an important role in exacerbation of chronic otitis media. The aim of this study was to analyse the microbiota in chronic otitis media in the context of local treatment., Method: In this prospective study, samples for microbiological examination were taken from 119 patients who underwent operation because of chronic otitis media., Results: The results were compared between groups depending on the type of operation (none, tympanoplasty or radical), the presence of cholesteatoma or granulomatous tissue or discharge from the ear as a symptom of exacerbation. Antibiotic susceptibility of germs was analysed to define the strategy of treatment. A total of 209 samples were collected from 119 patients with chronic otitis media., Conclusion: Pseudomonas aeruginosa and Staphylococcus aureus were pathogens most frequently identified from the ear in the course of chronic otitis media. Pseudomonas aeruginosa was concerned with major pathology of the middle ear (radical surgery, cholesteatoma or granulomatous tissue, persisting discharge after treatment), whereas Staphylococcus aureus was obtained in dry perforations without other pathology in the middle-ear cavity. Ciprofloxacin was effective against Staphylococcus aureus, but Pseudomonas aeruginosa strains were ciprofloxacin resistant.

Introduction: Surgical treatment of conductive hearing loss runs the risk of damage to the inner ear in the mechanism of acoustic trauma., Aim: The aim of this study was to evaluate the function of the organ of Corti, expressed as bone conduction threshold at the frequency of 4000 Hz for selected operations: mastoidectomy and canal-wall-down procedure., Material and Methods: The material was collected from patients with chronic otitis media in the Department of Otolaryngology and ENT Oncology, Collegium Medicum of Nicolaus Copernicus University in Bydgoszcz in 2004-2009. All patients were examined with pure tone audiometry threshold before surgery and at least three years after surgery. The analyzed group of patients was divided into subgroups depending on the type of operation according to To classification and procedures for resection: mastoidectomy and canal-wall-down procedure. The results were statistically analyzed., Results: In the analyzed period of three years after surgery there was no statistically significant difference between groups, although there were higher values for tympanoplasty type 1 with mastoidectomy compared with tympanoplasty type 1 without mastoidectomy - respectively 25.67 dB and 18.53 dB. In the study, there was no statistically significant the difference in bone conduction threshold for frequency 4000 Hz within the type 2 tympanoplasty according to Tosa comparing canal wall-up and canal-wall-down procedure., Conclusions: Mastoidectomy or canal-wall-down procedure do not affect the bone conduction threshold for a frequency of 4000 Hz after tympanoplasty in long-term observation.

Introduction: The method of tympanic membrane repairing is called myringoplasty., Aim of the Study: We analysed the reasons of failure of this procedure., Material and Methods: The structural results were observed among 36 patients under restricted criteria with diagnosed chronic otitis media. The unsuccessful procedure was one with reperforation. We studied Eustachian tube function and also localisation and size of the perforation., Results: The failure rate was 25%, which was mainly observed among individuals with incorrect Eustachian tube function - 70% and margin perforations - 50%. The localisation and the size of the perforation did not matter., Conclusions: The main reasons of myringoplasty failure were incorrect Eustachian tube function and margin perforations of tympanic membrane., (Copyright © 2013 Polish Otorhinolaryngology - Head and Neck Surgery Society.

Objective: The aim of the study was to evaluate the results of the tympanoplasty in chronic otitis media in its functional aspect., Methods: We analysed and categorized 489 tympanoplasties using Wullstein classification. The operations were performed in the Otolaryngology and Laryngological Oncology Department of the University School of Medicine in Bydgoszcz, Poland, from 2004 to 2009. The group consisted of 421 patients (221 women, 253 men, mean age 52.2 years)., Results: Type I tympanoplasty was performed in 133 patients (31.59%), type II tympanoplasty was performed in 191 patients (45.36%), type III tympanoplasty was performed in 93 patients (22.09%) and type IV tympanoplasty was performed in 4 patients (0.95%). The audiometry was done one year after the operations. We observed good effect in 116 cases (86.9%) of type I tympanoplasty, good or satisfactory in 150 cases (78.6%) of type II tympanoplasty and satisfactory in 63 cases (67.7%) of type III tympanoplasty. There were no hearing improvement and its deterioration results in 61 cases (14.48%), including all treated by type IV tympanoplasty., Conclusions: 1. There were improvement of hearing in audiometry in majority of our patients. 2. The functional effect of hearing depends on the function of conductive mechanism of the ear before the treatment. 3. We prefer among all types canal wall-up tympanoplasty., (Copyright © 2012 Polish Otorhinolaryngology - Head and Neck Surgery Society. Published by Elsevier Urban & Partner Sp. z.o.o.
