[Reconstructing or pulling down tongue-base in surgical treatment of laryngeal cancer]

The surgical treatment of laryngeal cancer, especially for the supraglottic cancer, usually involve the management of tongue-base, which is important in the rebuilding laryngeal function. There was no simple and effective method to repair tongue-base previously, which was removed for the greater part when invaded by advanced laryngeal cancer. As a result, many cases could not regain the satisfactory laryngeal function. And only several published reports focused on the efficacy of rebuilding laryngeal function by means of tongue-base flap. In order to develop a simple and reliable method to rebuild the laryngeal function, the management of tongue base in surgical treatment of laryngeal cancer was explored.

After the laryngeal carcinoma or the involved tongue-base was removed, according to the extent of surgical defect, sternohyoid myofascial flap was used to reconstruct the tongue-base, or the tongue-base was selected to rebuild the laryngeal function when greater part of it was preserved.

Out of the 32 cases with partial laryngectomy, 26 cases were decannulated with a decannulation rate of 81.3%, all the cases regained speaking functions except 4 cases undergone total laryngectomy. All the cases resumed normal diet, none presented complication of accidental aspiration. The 3-year and 5-year survival rates were 81.3% and 65.6%, respectively.

Reconstructing or pulling down the tongue-base is highly effective in rebuilding satisfactory laryngeal function, which is easily and simply performed with less damage and complications, appropriate for surgical treatment of laryngeal cancer.
