Secondary placement of a voice prosthesis after total pharyngolaryngectomy with colon interposition: voice restoration in colon interposition.

We present a patient treated by a total pharyngolaryngoesophagectomy and postoperative radiotherapy for a hypopharyngeal T4N2bM0 squamous cell carcinoma. The upper digestive tract was reconstructed with a pedicled left colon interposition through the posterior mediastinum. A voice prosthesis was placed 9 months after the initial treatment, following measurement of the tracheo-neopharyngeal wall thickness by sonography. Fifteen months after the total pharyngolaryngectomy, the patient remains free of recurrent disease and has successfully resumed speaking with the voice prosthesis.
