Background: Chronic suppurative otitis media (CSOM) attributes to 71.6% of hearing impairment in which most of them only have central perforation without any ossicular erosion or middle ear pathology. Tympanoplasty has evolved to provide and reconstruct better hearing mechanism, avoid complications as well as recurrence. Traditionally over the decades, tympanoplasty has been done using an operating microscope. Middle ear endoscopy was first introduced by Mer and colleagues in 1967, since then middle ear surgeries which were traditionally done using the microscope can be done using the endoscope also.
Methods: This prospective study was conducted at Basaweshwar Teaching and General Hospital, Kalaburagi between March 2016 to November 2017. Endoscopic type 1 tympanoplasty was performed in all the cases using temporalis fascia.
Results: There were 30 patients between 15-65 years with average being 29.6 years in which 17 were females and 13 were males. Pre and post-operative PTA at 1, 3 and 6 months were analyzed. The mean duration of surgery was 50.13 mins. The mean duration of hospital stay was 2.23 days. The mean duration of wound healing was 12.23 days. The average pre-operative PTA was 32.47±4.79 dBHL and postoperative PTA at 1, 3 and 6 months was18.3±3.22 dbHL, 16.5±2.2 dbHL and 16.35±2.22 dBHL. The graft uptake at end of 6 months was 100%.
Conclusions: We here by conclude that endoscope can be a better alternative for microscope in type 1 tympanoplasty as it provides a wide panoramic view, less operating time and hospital stay with minimal visible scar post operatively.
