Staged Surgery in Ears With Excessive Disease of Tympanum

Late post-operative hearing results correlated with the severity of tissue changes in ears with chronic otitis media

“…The tympanic mucosa was left intact, if it was nearly normal or only oedematous, but granulations, polypi or epidermized parts were removed. If the mucosa was removed, the raw surface of the promontory was covered with a thin silicone elastomer sheet (Silastic®) or with temporary paraffin filling, from the orifice of the eustachian tube to the area of oval window and facial nerve (Palva, 1963;1973: Palva et al, 19681975).…”

“…Adhesive changes in the tympanum, infections, reperforations, recurrences of cholesteatoma, and breaking up of the reconstructed ossicular system are the most important factors causing post-operative deterioration of hearing (Palva et al, 1968;Sheehy and Crabtree, 1973;Ojala, 1979) which may happen over a period of several years following surgery (Tos, 1974;Ojala, 1979). The method of ossicular reconstruction and other features of the operation have an important effect on the hearing results (Ojala, 1979), the management of the tympanic mucosa at operation being decisive in this respect (Palva et al, 1968;1975).…”

“…Regardless of the operative technique, the mean hearing is only slightly better, and sometimes it may be even worse, after surgical treatment of chronic otitis media than the pre-operative hearing (Palva et al, 1975;Palmgren, 1977;Ojala, 1979). Fikentscher et al (1978) regarded surgical treatment in this connection as solely a means of preserving hearing, not of improving it…”

An unusual prevalence of complications of chronic suppurative otitis media in young adults

“…Accordingly, it would be expected that the handicap of a chronically discharging ear with a complication is safely rectified by a thorough clearance operation which may result in some loss of hearing. Restoration of the latter by reconstructive procedures can always be attempted later on a safe dry ear as recommended by Palva et al (1975).…”

Late results of tympanoplasty using ossicle or cortical bone

“…The hearing results of tympanoplasties in Whatever operative technique is used, the connection with radical chronic ear surgery post-operative hearing after radical chronic are often unsatisfactory and the hearing ear surgery is on the whole only slightly improvement aimed at is often very difficult better (and sometimes even worse) than the to obtain (Palva et al, 1975; Fikentscher pre-operative hearing (Palva et al, 1975;et aL, 1978;Ojala, 1979). Post-operative Palmgren, 1977;Ojala, 1979) and that is adhesions in the tympanum, infections, why Fikentscher et al (1978) regarded reperforations and recurrences of surgical treatment in this connection only as cholesteatoma are important factors leading a means of preserving hearing, not of to unsatisfactory hearing results and to improving it deterioration of hearing during the post-Tympanoplastic methods have advanced operative period (Palva et al, 1968;Sheehy considerably since Wullstein and Zollner and Crabtree, 1973;Ojala, 1979).…”
