| dc.description.abstract | ABSTRACT Background The endoscopes have better optics and magnification with wide angle of view due to angled lenses. It provides the excellent resolution of image in surgeries having many difficult anatomic nooks and corners like; antero-inferior recess of external auditory canal, middle ear cavity and difficult areas to visualize under microspore like sinus tympani. Likewise, the use of cartilage has very low metabolic rate, provide support to prevent retraction and reacts minimally to inflammatory reaction, so it has advantageous role in closure of tympanic membrane perforations. Objective The main objective of our study is to see the graft uptake rate and hearing results after endoscopic cartilage myringoplasty with our own modification. Method This is a prospective, cohort study conducted among 37 patients who underwent endoscopic modified inlay butterfly cartilage perichondrium myringoplasty using tragal cartilage. The hearing was assessed by comparing pre with post-operative ABG (Air bone gap) and ABG closure in speech frequencies (500Hz, 1KHz, 2KHz, 4KHz). Result Among 42 patients, 37 (88.09%) had graft uptaken. Other five patients had residual perforation because of infection. The post-operative ABG was smaller than pre- operative ABG.(26.41±8.47dB and 36.57±12.13dB respectively). The mean ABG closure was 10.15±10.23dB. The ABG closure was ≤ 10dB in 28(75.6%) patients. Conclusion Endoscopic modified inlay butterfly cartilage perichondrium myringoplasty has advantages in terms of hearing results and graft uptake rate as it is comparable or even better than others. So, it is advisable to perform this technique without any difficulty. KEY WORDS Air bone gap, cartilage, endoscope, myringoplasty | |
