[Musical abilities in children with an auditory processing disorder]. / Musikalische Fähigkeiten bei Kindern mit auditiver Verarbeitungs- und Wahrnehmungsstörung.

Objective Difficulties in solving musical tasks are observed in clinical practice in children with an auditory processing disorder (APD). There is a paucity of research on musical ability in children with an APD. Material and Methods To assess musical skills we had 15 children aged 6-11 years with the diagnosis of APD perform a test, and compared them to a control group of 15 children. Results APD children did significantly worse in pitch discrimination, reproduction of rhythm and singing. Correlations between language-based and musical skills in the APD-group were observed. Conclusions Greater attention should be paid to musical skills in APD diagnostics. The positive impact of musical training on language development and cognitive abilities in general has been demonstrated in numerous studies. Musical training should be the focus of further discussion for therapeutic methods of APD in the presence of musical deficits.

Stapes piston insertion depth and clinical correlations.

Background: The insertion of the stapes piston within the vestibule provides the physical basis for a successful stapedotomy. An insertion depth of 0.5 mm is recommended to avoid the dislocation of the stapes prosthesis (e.g. sneezing). Aims: The objective of this study is to analyze the depth of stapes prosthesis insertion and its correlation with clinical outcome. Material and methods: We observed in a retrospective case series 39 otosclerosis patients after a stapedotomy and a postoperative performed flat panel tomography/cone beam CT. The evaluation included the radiologically found depth of prosthesis insertion within the vestibule, the vestibule depth, and the correlation with the bone conduction (BC) threshold, vertigo, and tinnitus. Results: Insertion depth varied between 0.2 and 1.6 mm (mean 0.74 mm). The ratio of insertion depth versus the vestibule depth was between 8% and 59% (mean 26.6%). We observed no correlation between the insertion depth, the length of the prosthesis, the ratio of insertion depth/vestibule depth, postoperative BC, appearance of vertigo, or tinnitus. Conclusions and significance: In our group, we observed no significant relation between insertion depth of the stapes piston, postoperative vertigo, tinnitus, or decrease of the BC.
