Pleural tap has been done & she is now on ATT.
Total Thyroidectomy is planned.
How to manage her Subglottic part of papillary Ca?
I feel that tracheal resection is not possible as the tumor is extending into submucosa of Cricoid cartilage.
One option is endoscopic shaving of the tumor with a microdebrider.
Should the larynx be stented after that?
Can the procedure(tumor shaving) cause subglottic stenosis?
Intra-tracheal mass is too large to be ablated by Radio-iodine.
Photos of case & CT films of neck attached.
