Transection of the supraclavicular nerve (SCN) through supraclavicular incisions can lead to debilitating neuroma formation. Targeted muscle reinnervation (TMR) proved to be an effective technique for the prevention and treatment of neuroma. In this case series, we propose the TMR of the SCN to the motor branch of the omohyoid muscle (OM) to prevent the formation of neuroma and avoid chronic pain at the supraclavicular area after thoracic outlet syndrome (TOS) procedures. A total of 10 patients underwent the procedure. Dissection of the SCN and its branches was performed through a supraclavicular incision. The branches were transected close to the clavicle. The inferior belly of the OM was identified and its motor branch isolated. Coaptation of the SCN branches with the motor branch of the OM was performed under the microscope and the wound was closed in layers. All the patients denied pain or hypersensitivity at the supraclavicular area on follow-up. In summary, the motor branch of the OM is a viable recipient for the TMR of the SCN and can prevent and treat painful neuromas at the supraclavicular area with minimal morbidity.
