Results: Out of 68 patients affected by acquired primary cholesteatoma and who underwent exclusive endoscopic transcanal tympanoplasty, 23 had intraoperative integrity of the ossicular chain (17 male and 6 female subjects; mean age, 40 yr) and were included in the study. An inverse
correlation was found between number of subsites involved and chain preservation (Spearman rank correlation coefficient, r = -1; p = 0.017). Medial attic involvement was the factor that most negatively influenced the likelihood of chain preservation.
Conclusion: Middle ear endoscopic techniques may increase the likelihood of ossicular chain preservation during cholesteatoma surgery. Medial attic involvement and a high number of subsites involved represent the most significant negative factors for chain preservation. The rate GDC-0068 manufacturer of residual disease requires more thorough evaluation in the future to validate the results.”
“Here we report a clinical phenomenon that we have observed repeatedly in clinical research settings; namely, a triggering and/or exacerbation of head
tremor during or immediately following sustained phonation. To our knowledge, it has not been reported previously nor has it been the subject of study. Here we: 1) report the phenomenon, 2) provide several visual illustrations, 3) estimate its prevalence, and 4) analyze its clinical correlates. Head tremor was assessed qualitatively, and scores were assigned pre-, during, and post-sustained phonation using the Tremor Research Group Essential Tremor Rating Assessment Erastin Scale. Seventy (68.6%) of 102 essential tremor (ET) patients exhibited a qualitative increase in head tremor amplitude during and/or immediately after sustained phonation; in 5 (4.9%), head tremor would not have been detected without the voice activation maneuver (i.e., it was not visible at any other point in the videotape aside from the period during/immediately following sustained phonation). Women were more likely than men to exhibit this
phenomenon (p = 0.05), whereas age, age at onset, duration of tremor, and total click here tremor score did not predict responsiveness of head tremor to sustained phonation. Sustained voice activation is a useful examination maneuver that may elicit or amplify head tremor in ET. Head tremor is not reported to occur in patients with enhanced physiological tremor. Thus, this maneuver, by triggering head tremor, may be a useful diagnostic supplement, particularly in research/clinical settings where arm tremor is mild and the diagnosis (mild ET vs. enhanced physiological tremor) would otherwise be ambiguous.
