Abstract SUMMARY This work was carried out with the aim of pattern of tympanometric measurements after myringoplasty and its comparison with the pre operative hearing function. studying successful and postour subjects were selected from patients presenting to the ear, nose and throat clinic of the military hosipitals. 30 Patients out of 72, who underwent myringoplasty were included in this study. successful * The criteria of sUbject selection before--surgery was based on the following : Simple dry perforation as shown by clinical examination, conductive hearing loss with normal bone conduction curve by the aid of audiometry, an intact mobile ossicular chain and a good eustachian tube function. * operative data gathered during exploration of the middle ear concerning the state of the ossicular chain, the state of tympanic orifice of eustachian tube and the state of middle ear mucosa. * Pot months -operative evaluation after one month was followed based on complete and three otological 89 -_.-.--_._-------- -,~,--- -~- --~~~~~-------- ---- ------- ----- examination, pure tone and speech tympanometry and stapedius reflex. aUdiometry and The study showed the following results: 1- A significant relation was found between post-operative compliance value on one hand and site of the perforation, surface area of the perforation and technique of myringoplasty on the other hand. 2- A significant relation was found between site of the perfoeration and degree of pre-operative hearing loss. 3- No significant relation was found between pre-operative hearing loss and post-operative compliance. 4- No operative significant relation compliance and time. was found between post- 5- No operative significant relation was compliance and Age or sex. found between post- 6- No significant relation was found between surface area of the perforation and post-operative air-bone gap and hearing gain. 90 -----_._---_._-_. __... - --- ... 7- No significant relation was found between technique of myringoplasty and post-operative air-bone gap and hearing gain. 8- No significant relation was found between period of follow-up and post-operative air-bone gap and hearing gain. 9- No significant relation was found between operative compliance and post -operative air bone hearing gain. postgap and 10- The presence or absence of the stapedius reflex was related to the type of tympanogram and nature of pathology of the middle ear more than post-operative air-bone gap and hearing gain. |
