Assessment of the endoscopic range of motion for head and neck surgery using the SOLOASSIST endoscope holder

A ‘third hand’ is useful for holding the endoscope during surgery. The SOLOASSIST camera holder (AktorMed GmbH, Germany), which is used for abdominal surgery, is supposed to be modified for head and neck surgery. The aim of this study was to determine the intraoperative hand‐held endoscopic range of motion for different surgical procedures and to define the required technical changes.
