Conditions

Tonsillectomy

Brief summary

The purpose of this study is to assess 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.

Detailed description

Study Design: Prospective, multi-center, single-arm non-comparative pilot study to assess the severity of post-operative pain with the use of BiZact™ for tonsillectomy. Study Visits: * Screening * Surgery, Day 0 * Post-Op Follow-up Day 1 - Day 7 & Day 10 (Home assessments) * Post-Op Follow-up Day 14 (Office Visit)

Interventions

DEVICEA 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.

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
