Minimally invasive surgeries are widespread and technically enhancing. Thyroidectomy is a common surgery and non-invasive adjustments make it more interesting. Neighbor neurovascular bundles need to be protected during minimally invasive thyroidectomy. A 15 yr old female who underwent minimally invasive thyroidectomy due to nodule, had presented with upper brachial plexus injury, without proper recovery despite physiotherapy cessions. She was operated in 2 stage reconstructive surgeries. First, musculocutaneous nerve innervated by 2 branches of median and ulnar nerves. Then, in a compound operation, axillary nerve innervated by long head branch of triceps nerve and suprascapular nerve by accessory nerve. She gained good function of upper limb. Minimally invasive operations in head and neck area can be disastrous, if surgeons do not consider anatomical points. Brachial plexus reconstructive surgeries are complicated operations to preserve hand functions following iatrogenic injuries.
