Endosupralayngeal laser resection of a symptomatic anatomical laryngeal variant: a minimally-invasive technique for a newly-recognised condition.

A variant of thyroid cartilage anatomy has recently been described as a cause of significant pharyngeal and laryngeal symptoms. After clinical recognition, spiral CT imaging confirms the anatomical relationships and a minimally-invasive technique is offered to allow surgical removal of the variant. The authors describe the surgical technique that was developed to avoid the need for an alternative, more conventional, external approach, and the instruments found to be particularly suitable for providing appropriate access to the supralaryngeal region.
