Arm && Interventions

Group	Intervention	Description
A bipolar instrument for tonsillectomies	A bipolar instrument for tonsillectomies	A bipolar electrosurgical device that employs RF energy and pressure to ligate vessels interposed between its jaws which can then be transected using the built in knife deployed by the device trigger.

Primary Outcome Measures

Name	Time	Method
Pain Assessment Using a Visual Analog Scale (VAS)	Post-operative Day 14	The severity of post-operative pain following the use of the BiZact™ device in adult (≥22 years of age in United States and ≥18 years of age in Europe) tonsillectomy procedures will be analyzed at each post-operative assessment: at days 1 through 7, 10 and 14. This pain score will be assessed quantitatively using the VAS scale and qualitatively using the below subgroups: * No Pain: VAS= 0; * Mild Pain: VAS \> 0 and \< 4; * Moderate: VAS ≥ 4 and \< 7; * Severe: VAS ≥ 7

Secondary Outcome Measures

Name	Time	Method
Time to Normal Diet Following the Use of the BiZact™ Device in Adult (≥22 Years of Age in United States and ≥18 Years of Age in Europe) Tonsillectomy Procedures	Post-operative Day 28	Ability to return to Normal, subject's baseline, diet. EORTC Quality of Life Questionnaire (EORTC QLQ -H\&N35) will be analyzed at each post-operative assessment: at days 1 through 7, 10 and 14. The module consists of 35 questions assessing symptoms and side effects of treatment, social function, and body image/sexuality. The head and neck cancer module incorporates seven multi-item scales that assess pain, swallowing, senses (taste and smell), speech, social eating, social contact, and sexuality. There are also eleven single items. For all items and scales, high scores indicate more problems. This score will be assessed qualitatively by asking if they have experienced symptoms or problems using the below subgroups: * Not at all: 1; * A little: 2; * Quite a bit: 3; * Very much: 4
Time to Normal Activity Following the Use of the BiZact™ Device in Adult (≥22 Years of Age in United States and ≥18 Years of Age in Europe) Tonsillectomy Procedures	Post-operative Day 28	Ability to return to Normal, subject's baseline, activity. EORTC Quality of Life Questionnaire (EORTC QLQ -H\&N35) will be analyzed at each post-operative assessment: at days 1 through 7, 10 and 14.
