Lateral conservative approach for recurrent/persistent hypopharyngeal carcinoma: a case series.

purposeEarly persistent/recurrent hypopharyngeal tumours represent a challenge for surgeons who have to balance the need for oncological radicality and the desire to maintain a functioning larynx with preservation of the patient's quality of life. The aim of this study was primarily to understand the technical feasibility, functional outcomes, and the possibility of obtaining oncological radicality using lateral hypopharyngectomy with laryngeal preservation in early recurrent post-radio/(chemo)therapy hypopharyngeal tumours.

methodsPatients with recurrent T1 hypopharyngeal squamous cell carcinoma were retrospectively selected from our institutional database. The external lateral approach according to Spriano and a modified lateral hypopharyngectomy with laryngeal preservation were used to resect tumours of the lateral pyriform sinus wall. Reconstruction was obtained by direct approximation of the posterior border of the sectioned thyroid cartilage to the posterior hypopharyngeal wall, and this was reinforced with a second layer of vascularised and non-irradiated tissue that was provided by a microvascular fascial anterobrachial flap. Swallowing was assessed 3 weeks after surgery using videoendoscopic evaluation.

resultsThe surgical procedure was technically feasible, and complete resection was obtained in all patients. None of the patients experienced major post-operative complications (salivary fistula, bleeding, aspiration pneumonia). Mild dysphagia was observed in one patient who underwent swallowing rehabilitation. Tracheostomy was closed in all patients. No recurrence was recorded after a median follow-up of 20 months.

conclusionThe reported experience shows that, in selected cases, it is possible to radically remove lateral hypopharyngeal cancer with acceptable functional results.
