Opis:
Objective: The aim of the study was to evaluate risk factors influencing the results of tympanoplasties on the base of material taken from the Department of Otolaryngology and Laryngological Oncology Collegium Medicum of the Nicolaus Copernicus University in Bydgoszcz between 2004-2009. In this period, 98 operations were performed. The time from operations to hearing examination was 3 to 7 years, mean 5,43. Tympanoplastic operations were divided according to Tos classification. Measuring hearing results, tonal audiometry was done and mean air bone gap on four frequencies was assessed (500, 1000, 2000, 3000 Hz), according to AAO-HNS guidelines (1995). This parameter was compared between groups separated according to risk factors, that could potentially affect the results. Those risk factors were: disfunction of the Eustachian tube, location and size of the perforation of the tympanic membrane, damage of the ossicles, the state of the mastoid process, the number of operations, the presence of the cholesteatoma or granulating tissue, chronic otitis media in the opposite ear, smoking cigarettes, mastoidectomy, canal wall down technique. The results were analyzed using statistical test. Results: The most important risk factor affecting treatment results (besides discharge from the ear) is damage of the ossicles, especially the malleus and stapes. A properly performed operation ensures good hearing results irrespectively of the presence of cholesteatoma or granulating tissue, and also in case of reoperation. For all types of tympanoplasties neither the location, nor the size of perforation influence the hearing results in long-term observation.

Opis:
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.
