Symmetrical placement of bilateral percutaneous bone-anchored hearing systems via guide-marker.

Objectives: To investigate the use of a novel technique to estimate the symmetrical placement of percutaneous bone-anchored hearing systems (BAHS) with a guide-marker in patients undergoing bilateral surgery with this device.

Study Design: Prospective cohort study.

Methods: A guide-marker and anatomical landmarks were used to estimate the implant placement and transferred to the contralateral ear in 12 subjects eligible for bilateral BAHS surgery.
