Methylene Blue Dye as tool for Safe Thyroidectomy

INTERVENTION: Intervention1: Use of Methylene Blue Dye Spraying during Thyroidectomy: This intervention will help in easy identification of Recurrent Laryngeal Nerve and Parathyroid Gland as compared to Conventional Anatomical Identification Control Intervention1: Use of Methylene Blue Dye Spraying during Thyroidectomy: The two methods of identification of Recurrent Laryngeal Nerve and Parathyroid Gland is being compared. Use of Methylene Blue dye will aid in identification and also reduce duration of procedure.
