Contralateral Rerouting of Hypoglossal Nerve Implant Pulse Generator and Stimulation Lead

Area of Science:

• Otolaryngology
• Neurosurgery
• Sleep Medicine

Background:

• Obstructive sleep apnea (OSA) is increasingly managed with hypoglossal nerve stimulators (HNS).
• Standard surgical techniques for HNS implantation may require modification in specific clinical scenarios.
• Concurrent medical conditions can necessitate revision or adaptation of existing HNS systems.

Observation:

• A patient required revision of a left-sided HNS implant to accommodate upcoming breast cancer surgery.
• The existing HNS required significant surgical modification to facilitate the new treatment plan.
• This presented a unique surgical challenge requiring adaptation of the standard implantation procedure.

Findings:

• The report details the first contralateral rerouting of an HNS stimulation lead to a left-sided impulse generator.
• It also describes the novel placement of a respiratory sensing lead in the left second intercostal space for an HNS device.
• These modifications allowed for successful HNS revision while accommodating the patient's oncological treatment.

Implications:

• This surgical approach offers a potential solution for HNS revision in patients requiring concurrent thoracic or breast procedures.
• The described techniques expand the surgical repertoire for managing HNS systems in complex cases.
• This case highlights the adaptability of HNS implantation techniques to evolving patient needs and co-existing medical conditions.
