Current approaches to the management of early stage glottic carcinoma include radiation as one of the primary modalities of therapy. While local control rates are high, when radiation fails the options for partial laryngectomy and preservation of voice are limited as radiation injury to the local tissues compromises the usual reconstructive options. This paper describes a new technique for reconstruction of the larynx using the free temporoparietal flap as vascular carrier for grafts of mucosa and cartilage. The paper reviews our experience with 18 consecutive patients undergoing laryngeal reconstruction for T1 and T2 glottic carcinomas who have failed radiotherapy. Outcome measures of vocal quality, and objective assessment of patients perception of vocal disability, flap success and time to decannulation are presented. All patients have been decannulated with an average of 12 days to decannulation. Voice results vary from fair to excellent depending on the extent of larygeal resection. The objective voice index suggests that most patients feel their voices are improved from the pre-surgical state. There were no flap failures or partial flap losses in this series of patients. The technique of the free temporoparietal flap as a vascular carrier for reconstruction of the larynx following radiation failure appears to show promise in this pilot series of patients
