Randomized Controlled Trial Comparative Study
Evaluation of Electrostimulation Effect in Women With Vocal Nodules.
To evaluate the effect of transcutaneous electrical nerve stimulation (TENS) with and without tongue trills in women with vocal nodules. ⋯ TENS applied alone or combined with tongue trills was associated with improved glottal closure and phonation comfort. TENS associated with tongue trills yielded improved voice quality.

Supraglottic Airway Devices and Effect on Voice-Comparison of LMA Proseal and i-gel: Double-Blind Randomized Clinical Trial.
Laryngeal mask airway (LMA) is an important alternative to endotracheal intubation for all professional voice users undergoing surgery. However, dysphonia is a known complication of LMA Proseal (PLMA) use. The i-gel airway (IGA) provides adequate airway seal without the need for an inflatable cuff. Hence, it helps to minimize the risk of tissue compression. This study compares effect of PLMA and IGA on voice at 24th hour after anesthesia. ⋯ PLMA and IGA both produce comparable and significant deterioration in acoustic variables at 24th hour after short duration general anesthesia.

Teachers are one of the professional voice users. Voice problems are common among them. Female teachers are known to have more voice problems than male ones. Furthermore, there are only few studies on the voice of Iranian female teachers. The present study investigated the acoustic parameters of voice in Iranian female teachers and compares them with nonteachers. ⋯ It can be concluded that vocal overuse, abuse, or misuse during teaching over a period of time result in achievement of inadequate phonatory pattern with excessive musculoskeletal tension, and the possible result is tissue changes in teacher's voice. In addition, acoustic analysis of voice parameters for teachers may significantly contribute to the objective voice examination of this group.

The present study aimed at evaluating the effect of deep brain stimulation (DBS) of the caudal zona incerta (cZi) on voice tremor in patients with essential tremor (ET). ⋯ On the group level, voice tremor in patients with ET was found to reduce when stimulating the cZi. Bilateral stimulation was indicated to be more effective in reducing voice tremor than unilateral stimulation. However, individual voice tremor outcomes suggest that not all patients benefit from cZi DBS. Severity of voice tremor at baseline may not be a good predictor of voice tremor outcome after cZi DBS. Patients should be informed before surgery regarding individual differences in response to DBS treatment.

Observational Study
Development and Validation of the Children's Voice Handicap Index-10 for Parents.
The Children's Voice Handicap Index-10 (CVHI-10) was introduced as a tool for self-assessment of children's dysphonia. However, in the management of children with voice disorders, both parents' and children's perspectives play an important role. Because a self-tool including both a children's and a parents' version does not exist yet, the aim of the study was to develop and validate an assessment tool which parallels the CVHI-10 for parents to assess the level of voice handicap in their child's voice. ⋯ CVHI-10-P is a valid tool to appraise parents' perspective of their child's voice disorder. The use of the CVHI-10 and the CVHI-10-P is recommended for objectively determining the level of voice handicap in children by parents and child.
