A PROSPECTIVE OBSERVATIONAL COMPARATIVE STUDY FOR POST OPERATIVE RESULTS IN ENDOSCOPIC VERSUS MICROSCOPIC TYMPANOPLASTY

Abstract

OBJECTIVES- Endoscopes are increasingly being used in middle ear surgery as an adjunct to or replacement for the operative microscope. The superior visualization of hidden areas and a minimally invasive transcanal approach to the pathology are some of the endoscope's advantages. The aim of this review is to compare the surgical outcomes of a totally endoscopic transcanal approach with a conventional microscopic approach for tympanoplasty in patients with chronic otitis media (COM) in order to establish if endoscopic tympanoplasty could be a better alternative to microscopic tympanoplasty also we compare the advantages and disadvantages of endoscopic tympanoplasty and microscopic tympanoplasty
SUBJECT AND METHODS- A Prospective observational study for endoscopic tympanoplasty and microscopic tympanoplasty was conducted on 100 patients , 50 in each group of age group between 18 to 60 years attending ENT OPD and admissions under DEPARTMENT OF OTORHINOLARYNGOLOGY AND GMH HOSPITAL REWA. Subjects with dry central perforations due to csom mucosal type was selected for microscopic tympanoplasty. Similar subjects was selected for endoscopic tympanoplasty. Patients those with unsafe csom, SNHL, active infections,and discharge was excluded.
RESULTS- In our study 55 percents patients belongs to 25-40 years of age. Most of the patients have medium sized perforation (40%) followed by large central preforation (25%),small central perforation (20%) ,subtotal perforation (15%) respectively. According to quadrants involving perforation which is mainly AIQ, followed by Anterior superior quadrant ( ASQ), Posterior inferior quadrant (PIQ) and posterior superior quadrant (PSQ). Mean operative time was 50+/-15 minutes for endoscopic tympanoplasty and 90+/- 15 miutes for microscopic tympanoplasty
CONCLUSIONS- In our study, we have concluded that endoscopic tympanoplasty scores over microscopic tympanoplasty. Endoscopic tympanoplasty has helped patients achieve faster recovery, a shorter hospital stay, and a lower financial burden, which was especially helpful for developing countries like ours.
