Title : Evaluation of the Hearing Results after Mastoidotympanoplasty Operation with or without Ossiculoplasty: A Percentage Change versus Absolute Change; A Different Methodology
Purpose: Our article provides a comprehensive review of parameters of percentage change of the results regarding the documented
hearing results (not based on any particular classification) in ear surgeries in chronic suppurative otitis media (CSOM) cases.
Materials and Methods: Our series is a prospective cohort observational study in 230 cases of CSOM from 2009 to 2016 wherein we have
evaluated the hearing improvement with a parameter of percentage change of hearing improvement between preoperative and postoperative
period in various types of ear surgeries. Statistics and Results: A statistically significant difference was seen in 4 out of the 14 surgical groups,
namely, in mastoidotympanoplasty, modified radical mastoidectomy (MRM), and MRM with tympanoplasty and in tympanoplasty. The rest
of the 10 surgical groups had <10 cases, and therefore, the P significance could not be determined; however, these groups still showed hearing
improvement. Conclusion: The superiority of the surgical techniques such as mastoidotympanoplasty, MRM, MRM with tympanoplasty and
in tympanoplasty as demonstrated in our study aims to find an ideal surgical procedure in CSOM which gives the best chance to improve or
preserve the hearing with complete eradication of the disease.
