We developed and tested a pressure transducer to correctly determine swallowing pressure at different sites in the pharynx. In normal individuals three pressure peaks were obtained in the mesopharynx, hypopharynx and cervical esophagus, respectively. A patient with central dysphagia demonstrated markedly low mesopharyngeal and hypopharyngeal swallowing pressure. One tongue cancer patient who had undergone right hemiglossectomy, including partial resection of the root of the tongue and bilateral superior neck dissection, had markedly low swallowing pressure in the mesopharynx and vallecula area. Another supraglottic cancer patient treated by supraglottic horizontal partial laryngectomy showed extremely low swallowing pressure in the supraglottic area. Based on our findings, we suggest that measurements using a pressure transducer such as the one described here should be used in combination with radiographic study to diagnose swallowing anomalies correctly. Data obtained with the pressure transducer will allow the clinician to identify the site responsible for postoperative dysphagia as well as its severity, and facilitate planning of reconstructive surgery when required. |
