Abstract


The clinical research work-study is to evaluate endoscopic and microscopic middle ear surgery for the repair of tympanic
membrane perforation in the treatment of chronic otitis media (COM) without cholesteatoma. Microscopic Ear Surgery
using a post-auricular approach is the most common tympanoplasty technique before the evolution of endoscopes. Endoscopic Ear Surgery, with
the advent of new instruments, became a more powerful surgical method in the treatment of ear disease [2] Endoscopic Ear Surgery, now called
transcanal endoscopic ear surgery TEES, provide wide-angle vision with high resolution and magnication of structures of the middle ear. The
endoscopic ear surgery helps to direct visualization of hidden areas such as the sinus tympani, the epi tympanum, meso tympanum, and the
hypotympanum [3, 4, 5]. The present study evaluates the tympanoplasties to treat chronic otitis media without cholesteatoma. The study
compares the surgical outcome of hearing restoration rates. It also helps to study the variant anatomy of the middle ear and pathology of csom at
the time of surgery.
Material and Methods: The clinical study of endoscopic and microscopic tympanoplasty for the treatment of csom work done in the
Department of Otorhinolaryngology and Head and Neck Surgery, NRI Medical College and Hospital and Research Centre Chinakakani, all
patients seeking services came to Dept of ENT with a diagnosis of tubotympanic type of CSOM pathology were selected. The sample size is 30
patients with ears divided into two groups, Group A microscopic and Group B endoscopic surgery.
Conclusion: The study showed no statistically signicant differences observed between two groups regarding surgical outcome and hearing.
The endoscopic group resulted in the successful healing of 96.2% of ears, whereas the microscopic group leads successful healing in 92% of
cases. The average hearing gain was 10.2 ± 6.5 dB in group A and 12.4 ± 7.5 dB in group B. The endoscopic transcanal approach introduced a new
perspective to ear surgery in the management of csom.
