Use of the Microdebrider for Laryngeal Surgery

概要

The microdebrider is a powered rotary dissection device with suction assistance. In recent years its usage has spread rapidly in otolaryngology. We reported on three cases with laryngotracheal stenosis to which we applied a microdebrider for airway surgery.<BR>Case 1 was a 32-year-old male, who underwent a tracheostomy because of glottic stenosis due to idiopathic bilateral vocal cord paralysis. An arytenoidectomy with a microdebrider guided by an endoscope was performed to treat his condition. After surgery, the posterior glottic space was sufficient and the tracheostomy was closed.<BR>Case 2 was a 52-year-old female, who underwent a tracheostomy due to laryngeal stenosis caused by cicatricial pemphigoid. A microdebrider was used for tracheal stenosis by cicatrix hyperplasia and a T-tube was kept in place for fixation of the airway.<BR>Case 3 was a 97-year-old female, with laryngeal carcinoma, who was suffering from severe glottic stenosis due to a neoplastic lesion. A tracheostomy was first performed, followed by tumor debulking which was accomplished using a microdebrider in an endoscopic procedure.<BR>Use of a microdebrider secured a good field of view during the operation. In addition, the microdebrider was considered of high utility value in laryngeal surgeries performed in conditions requiring narrow operation fields.
