Three-dimensional reconstruction of supraglottic structures after partial pharyngolaryngectomy for hypopharyngeal cancer.
OBJECTIVE
Larynx-preserving surgery is frequently performed for advanced hypopharyngeal cancer involving the larynx. However, reconstruction after partial pharyngolaryngectomy (PPL) remains a challenging problem because of the high risk of postoperative aspiration. In this report, we describe our new three-dimensional method for reconstructing supraglottic structures with a radial forearm flap. This is a retrospective analysis of 20 patients who underwent PPL for having hypopharyngeal cancer involving the larynx at our institution from 1996 to 2005.


METHODS
The resulting pharyngolaryngeal defects were reconstructed with radial forearm flaps in all patients. Three-dimensional structures were reconstructed with a single nylon suture, which was used to hoist the flap and ensures that the arytenoids and the aryepiglottic fold were of appropriate height.


RESULTS
Radial forearm flaps were transferred successfully in all but one case. Swallowing function was satisfactory in all patients, and decannulation could be performed in all but one patient. Postoperative conversational function in all patients was rated as excellent with Hirose's scoring system.


CONCLUSIONS
Free jejunum transfer is the method of first choice for reconstruction of a defect after partial hypopharyngectomy. However, the complex supraglottic structures of the larynx are difficult to reconstruct with a free jejunal graft after PPL. In such cases, we perform three-dimensional reconstruction of the pharyngolaryngeal defect with a radial forearm flap and have achieved satisfactory postoperative function. We believe that our new procedure is a useful method for functional reconstruction after PPL.
