A COMPARATIVE STUDY OF ENDOSCOPIC MYRINGOPLASTY V/S MICROSCOPIC MYRINGOPLASTY

Abstract

INTRODUCTION Chronic suppurative otitis media (CSOM) is one of the common Otological conditions in India for w h i c h p a t i e n t s s e e k a d v i c e f r o m a n Otorhinolaryngologists. Poverty, illiteracy, overcrowding and poor hygiene are all factors which play an important role in the causation of the disease. Various surgical modalities of treatment have been tried since ages to eliminate this disease from the middle ear cleft. The use of the surgical microscope brought revolutionary advances into the field of Otological surgery because its new technology expanded the ability of surgeons to see in limited confines of the temporal bone. Initially endoscopes were used only for diagnostic and photographic purposes but now endoscopes are being used more and more for surgical purposes. The current study attempts to study the advantages and disadvantages of endoscopic myringoplasty in comparison to the conventional microscope assisted myringoplasty. OBJECTIVES To e v a l u a t e t h e e ffi c a c y o f E n d o s c o p i c myringoplasty with Microscopic Myringoplasty with reference to hearing and graft uptake MATERIALS AND METHODS Fifty cases of clinically diagnosed chronic suppurative otitis media with dry central perforation were taken into account of which 25 cases were undergone endoscopic myringoplasty a n d 2 5 c a s e s u n d e r g o n e c o n v e n t i o n a l myringoplasty. All patients were followed up till 6 months after surgery. RESULTS There was a strong statistical significant difference between the two groups (p=<0.001) for duration of surgery, hospitalization and hearing gain and graft uptake. In endoscopic and conventional groups of myringoplasty, the mean hearing loss improved to 16.88 dB and 19.76 dB respectively. CONCLUSION The surgical outcome of endoscope assisted myringoplasty was comparable in terms of tympanic membrane status after surgery, but in terms of duration of surgery, hospitalization and post-operative air bone gap patients in the endoscope group had better results.
