title: [Posterior pharyngectomy. Reconstruction using a free antebrachial transplant].
abstract: Cancers of the posterior wall of the oro or hypopharynx are rare and do not invade the larynx or the oesophageal orifice. Previously, these cancers were treated with radiotherapy alone, but since 1981 new techniques in reconstruction surgery have allowed a surgical approach. Cancerological non-mutilating exeresis is possible, but reconstruction is difficult since the flap must be very thin to allow normal food intake. In addition, flap reliability is extremely important due to the gravity of cervical salivary fistulation. We treated 15 patients with a lesion of the posterior wall of the pharynx using posterior pharyngectomy and reconstruction with a free antebrachial transplant which was revascularized and reinnervated. In two cases, the operation was performed in patients who had had previous radiotherapy. A branch of the external carotid and the internal jugular vein were used for vascular microanastomoses and reinnervation was obtained using the superficial cervical plexus. The transplant was placed over the prevertebral aponevrosis and sutured to the remaining pharyngeal mucosa. One postoperative death due to heart disease occurred at D + 11. All reconstructions were successful and two salivary fistulas on irradiated tissue closed spontaneously. Postoperative radiotherapy was performed in 11 cases (50-65 Gy) and was well tolerated. These results demonstrate that a highly flexible and thin free forearm transplant is perfectly adapted to reconstruction after posterior pharyngectomy. It is more reliable than local pediculated flaps.
