Voice disorders

This study tests whether combining semi-occluded vocal tract exercises (like phonating through a pipette) with breathing exercises (pursed-lip, segmental, and diaphragmatic breathing) can improve how long conservatory students can sustain a note and their overall lung function. P…

This study tested a new type of botulinum toxin injection (DAXI) for people with adductor spasmodic dysphonia, a condition that causes the voice to spasm and sound strained. 22 adults who had previously been helped by standard Botox injections received a single DAXI injection int…

This study tested whether a gentle brain stimulation technique called tDCS could improve voice quality and range in 45 healthy singers. Participants received either real stimulation to the motor cortex or cerebellum, or a sham (fake) stimulation, during voice training over 10 day…

This study looked at whether giving a low dose of a muscle relaxant (rocuronium) during bronchoscopy—a procedure where a tube is inserted into the lungs—could reduce complications like throat spasms and coughing. 153 adults having elective bronchoscopy were split into two groups:…

This study looked at how using high-flow nasal oxygen during laryngeal surgery affects the heart and blood vessels. Twenty relatively healthy adults were monitored for changes in heart function compared to standard breathing support. The goal was to understand potential risks, no…

This completed study tested two ways of helping patients breathe during microscopic throat surgery. One method uses a steady airflow, while the other uses a set volume of air. The goal was to see which method keeps airway pressure lower and safer. 68 adults having elective laser …
