Ipsilateral and bilateral DEH. Among the 56 patients who underwent an initial or revision transmastoid labyrinthectomy, symptoms were completely controlled in 49 (88%), including the three of the six (seven ears) who had failed ELS surgery (see case report 1) (table 3).
Including the bilateral case, a total of 68 surgical procedures were performed for ipsilateral DEH.
Contralateral DEH. All 16 patients with contralateral DEH whose vertigo was refractory to medical therapy underwent ELS surgery with various draining methods.
Five selected case reports follow, describing two patients with ipsilateral DEH, the one with bilateral DEH, and two with contralateral DEH.
Schuknecht and Gulya later described two unique temporal bone histopathologic studies in two patients with contralateral DEH. [7] They found that the histopathology in the deafened ear was typical of viral labyrinthitis (based on its similarity to the histopathology of ears deafened by mumps or measles) and that pathologic changes in the opposite ear were similar to those seen in Meniere's disease.
In 1978, Schuknecht wrote that there was no satisfactory therapy available for contralateral DEH. [3] In 1983, Morrison reported on ELS surgery on the only-hearing or better-hearing ear in patients with contralateral DEH and concluded that because the risk of surgical anacusis was only 1% with ELS surgery, it should be the only option for these patients.
