Study of Anatomical Results and Hearing Improvement in Various Types of Tympanoplasty Using Conchal Cartilage.

This study was undertaken for study of anatomical results and hearing improvement in various types of tympanoplasty using conchal cartilage. A total of 100 patients were taken for this study the patients belongs to varying age groups from 1st to 6th decade of life.Maximum patients were in between age group 21 to 30 years, 37 (37%) patients and minimum 02(2%) between age group 51 to 60 years. Out of these an overall average gain of 13.33dB in PTA(pure tone audiometry) as well as ABG(air bone gap) was seen however an overall average deficit of 32.15dB in PTA as well as 16.43dB in ABG was seen. The tympanoplasty performed were with or without any additional surgeries of mastoid like Cortical, Atticotomy, CWW, MRM.The pre and post ABG was mainstay for each of our case and final anatomical result of graft uptake. Key points: Type I Tympanoplasty had an average deficit of 15.26 in ABG. Type II Tympanoplasty had an average deficit of 12.75 dB in ABG. Type III Tympanoplasty had an average deficit of 19.42 dB in ABG. Type IV Tympanoplasty had an average deficit of 24 dB in ABG. An overall average gain of 13.33 dB in ABG was seen. An overall average deficit of 32.15 dB in PTA as well as 16.43 dB in ABG was seen. The main aim of our study is to counsel the patient that there will not be complete improvement of hearing if we have done type III and type IV tympanoplasty in advanced disease. This is also of importance for medicolegal purpose. [ABSTRACT FROM AUTHOR]
