The sensitivity and positive predictive value of the method are reported to be higher than 80%. Nevertheless, the visualization rate in male patients remains low; therefore, ultrasound is not attractive for the perioperative workup in those patients. In the present study, we evaluate the ability to improve the visualization rate for male patients by using a gel pad as an interface between the skin and the ultrasound probe.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and Materials<\/jats:title><jats:p>Between December 2018 and January 2019, 92\u00a0male patients (mean age 49 years; range: 20\u201380 years) referred to our hospital with different thyroid pathologies received a laryngeal ultrasound without (TLUS) and subsequently with gel pad (G\u2010TLUS).
