Surgical canal plugging is an effective treatment. We report the first use of a robotic system, originally designed for cochlear implantation, adapted for SCDS surgery. Methods: A 64-year-old woman with bilateral SCDS underwent robot-assisted transmastoid plugging on the left ear. The robot drilled two trajectories of 1.8 mm diameter to the ampullated and non-ampullated end of the SCC with submillimetric accuracy, followed by minimal manual mastoidectomy. Fenestrations (1 mm) were robotically created and the SCC manually plugged. Results: Postoperative computed tomography showed 0.37-0.48 mm target accuracy. Lateral and posterior semicircular canal function, as well as hearing, remained preserved. Autophony and pulsatile tinnitus resolved on the operated ear. Conclusion: This approach enabled minimally invasive, precise, and safe SCDS surgery.
