These are surgeries done on the larynx to remove various pathologies such as laryngeal cancer, laryngeal papilloma, laryngeal granulomas, etc. Total laryngectomy (open) is the complete removal of the larynx while partial is incomplete removal. This normally depends on the location and stage of cancer. Endoscopic laryngeal surgeries are getting common. Microlaryngeal surgeries are used to operate on one's vocal cord. Laser surgery is a recent addition.
