The medialization laryngoplasty is a surgical procedure to improve the voice function of the patient with vocal fold paresis and paralysis. An image guided system for the medialization laryngoplasty will help the surgeons to accurately place the implant and thus reduce the failure rates of the surgery. One of the fundamental challenges in image guided system is to accurately register the preope...

The ideal injectable agent for vocal fold medialization is biocompatible, durable, sized to prevent phagocytosis and migration, and formulated for easy injection and does not adversely affect the viscoelastic properties of the vocal fold. We tested a cohesive implant of calcium hydroxylapatite (CaHA) particles in a gel carrier in an in vivo canine model of phonation. Six dogs underwent unilater...

BACKGROUND Revision laryngeal framework surgery is usually performed for medialisation laryngoplasty failure, rather than for failure after arytenoid adduction. We describe a new method for revision arytenoid adduction surgery, performed by directly pulling the lateral cricoarytenoid muscle ('lateral cricoarytenoid muscle pull surgery'). METHODS We describe a case of revision laryngeal framew...

Surgical procedures require the physician to use preoperative and intra-operative information for deciding the optimal course of action to be taken on the patient. Medical visualization techniques are used to ‘guide’ the surgeon during the procedure to improve accuracy. We are presenting a visualization approach for image guided medialization laryngoplasty. A brief background is provided to des...

OBJECTIVES (1) Review and report our experience performing medialization thyroplasty (MT) in previously irradiated patients and (2) compare complications and voice outcomes in 2 cohorts (irradiated vs nonradiated) to evaluate safety and efficacy. STUDY DESIGN Case series with chart review. SETTING Academic medical center. SUBJECTS All patients (44 total) who underwent MT from 2011 to 2015...
