Background: The ultrasonic scalpel is a recently introduced device in head and neck surgery. Total thyroidectomy is the most common endocrine procedure performed by surgeons.

Methods: This was an open, phase IV, multicenter, randomized controlled trial (RCT) that compared the use of an ultrasonic scalpel with a conventional technique in patients who underwent total thyroidectomy.

Comparative analysis of perceptual evaluation, acoustic analysis and indirect laryngoscopy for vocal assessment of a population with vocal complaint.

Unlabelled: As a result of technology evolution and development, methods of voice evaluation have changed both in medical and speech and language pathology practice.

Aim: To relate the results of perceptual evaluation, acoustic analysis and medical evaluation in the diagnosis of vocal and/or laryngeal affections of the population with vocal complaint.

Study Design: Clinical prospective.
