USG guided supraclavicular brachial plexus block provides many advantages but is also associated with the rare complication of recurrent laryngeal nerve palsy, seen in 1.3% of cases. Recurrent laryngeal nerve palsy is mostly documented in right sided supraclavicular blocks than left sided supraclavicular blocks. Here, we report a case of 28 years old male undergoing right upper arm surgery under supraclavicular block who developed hoarseness of voice due to ipsilateral recurrent laryngeal nerve involvement which was followed up properly and managed successfully. https://aacc.tums.ac.ir/index.php/aacc/article/view/563
