<prompt> A high tracheostomy may be indicated in:Scleroma of the larynxMultiple papilliomatosis of larynxBilateral vocal cord paralysisCarcinoma of larynx  <response>: It is impoant in tracheostomy to refrain from causing any damage in the region of cricoid cailage. An exception to this rule is when a patient has laryngeal malignancy and under these circumstances tracheostomy should be placed high so as to allow resection of tracheostomy site at the time of laryngectomy - Scott Brown 7thed vol 2 pg. 2295 The high tracheostomy is generally avoided because of the postoperative risk of peri-chondritis of the cricoid cailage and subglottic stenosis. In cases of carcinoma larynx with stridor when total laryngectomy would be done, high tracheostomy is indicated.
