As the base of the tongue (BOT) plays essential roles in speech and swallowing, surgical resection of BOT cancer is typically avoided. Moreover, standard reconstructive procedures for larynx-preserving BOT defects have not yet been established.
We performed immediate flap reconstruction after wide resection of BOT cancer with laryngeal preservation. Herein, the functional and oncological results of our strategy were analysed.
We retrospectively evaluated patients who underwent extended BOT resection (including the oral tongue, upper/lateral oropharyngeal wall, epiglottis and false vocal cord) with laryngeal preservation between April 2006 and April 2016.
We classified defects involving the oral tongue or upper/lateral oropharyngeal wall as the lateral extension type and those involving the epiglottis or false vocal cord as the laryngeal extension type.
Lateral extension-type defects were closed primarily and filled with a deepithelialised skin or muscle flap.
Laryngeal extension-type defects were reconstructed using a bulky skin flap plus hyo-thyroid-pexy to create a neo-epiglottis.
Postoperative functional and oncologic outcomes were assessed.
