Summary

Impact of Intraoperative Spraying methylene blue In thyroidectomy

Detailed description

General anaesthesia ,supine position with hyperextension to the neck Low collar incision to the neck , incision to the skin and platysma muscle and fascia ,upper and lower flaps are developed ,separation of strap muscles and identification of the thyroid gland after freeing of investing fascia Ligation of the middle thyroid vein and ligation and separation of the superior pedicle away from the external laryngeal nerve At this point of operation and before ligation of inferior pedicle, methylene blue 0.05% spraying is applied to the field the amount varies according to size of the thyroid lobe and variation in population and neck size Thyroid gland stained by bluish color , recurrent laryngeal nerve not stained or minimally stained so we can avoid injury to it parathyroid glands get red of the stain after about 3 minutes so we can avoid injury to it thyroid gland lose its stain in about 15 minutes so we can remove any residual and decrease residual tissue or recurrence
