Management of epi- and mesotympanic XXXX by one-stage trans-canal atticotomy in adults.

@entity1 @entity3540 @entity66
UNASSIGNED: Surgical management of @entity3540 limited to the attic and/or mesotympanum remains controversial. The aim of this study is to evaluate the anatomical and the functional results of trans-canal atticotomy in this pathological condition. The records of 27 adult @entity1 treated from 2008 to 2014 who underwent trans-canal atticotomy for primary @entity3540 surgery were reviewed. Pre-operative physical examination, audiometry, and CT-scan have been analyzed. Intraoperative findings have been described as well as the surgical technique. Anatomical and functional results have been evaluated with a mean follow-up of 24      12.2  months, and the results of a CT-scan performed 1  year after surgery were examined to assess the presence of @entity66 . Surgeries were uneventful. During the follow-up, 1 @entity1 (4  %) experienced a retraction of the attical reconstruction; all the other @entity1 had a well-healed tympanic drum with stable attical reconstruction. The mean air-bone gap was 19      12.2 and 10      7.3  dB pre-operatively and post-operatively, respectively (mean      SD, p  =  0.001, paired t test). Twenty-two @entity1 (81  %) had no opacity suggesting residual @entity3540 in CT-scan. Four @entity1 (15  %) presenting an opacity at CT-scan underwent MRI study that was negative for residual @entity3540 . One @entity1 (4  %) had displacement of the ossicular prosthesis. In conclusion, @entity3540 restricted to the attic and/or mesotympanum can be removed in a one-stage technique with no visible residual at 1  year, and with closure of the air-bone gap by 50  %.
