Prevalence of Dysphonia in Metal Singers and the Impact of Vocal Education: A Subjective Analysis.

On average, the prevalence of subjectively indicated dysphonia in singers is higher than in the general population. When using extreme vocal techniques supraglottic structures are involved to protect the vocal folds. Most of the metal singers learn this specific singing style autodidactically.

Vocal Tract and Subglottal Impedance in High Performance Singing: A Case Study.

Objectives/hypothesis: The respiratory process is important in vocal training and in professional singing, the airflow is highly important. It is hypothesized that subglottal resonances are important to the singing voice in high performance singing.

Study Design: Single subject, prospective.

Craniotomy size for traumatic acute subdural hematomas in elderly patients-same procedure for every age?

Surgical treatment of acute subdural hematoma (aSDH) is still matter of debate, especially in the elderly. A retrospective study to compare two different surgical approaches, namely standard (SC, craniotomy size > 8 cm) and limited craniotomy (LC, craniotomy size < 8 cm), was conducted in elderly patients with traumatic aSDH to identify the role of craniotomy size in terms of clinical and radiological outcome. Sixty-four patients aged 75 or older with aSDH as sole lesion were retrospectively analyzed.

Acoustically Induced Vocal Training for Individuals With Impaired Hearing.

Objectives/hypothesis: Articulation, phonation, and resonance disorders in the speech of hearing-impaired-speakers reduces intelligibility. The study focusses on (1) whether nonacoustic feedback may facilitate the adjustment of the vocal tract, leading to increased vocal tract resonance, and (2) whether training with the feedback would be helpful for the subsequent formation of vowels.

Study Design: Prospective.

Laryngeal and Pharyngeal Movements During Inner Singing: A Cross-Sectional Study.

Introduction: Laryngeal and pharyngeal activity during inner singing is discussed in the context of vocal hygiene. Inner singing is defined as imagined singing, reading music silently, and listening to vocal music. When vocal rest is prescribed, doctors, speech therapists, and voice pedagogues recommend avoiding listening to music or reading music silently, since it is suggested that inner singing unconsciously influences the glottis, and thus moves the vocal folds involuntarily.
