The danger of the invisible Dental Plate

Abstract

Introduction: Oesophageal foreign bodies are a potential emergency, due to the risk of oesophagealperforation leading to mediastinitis which has a significant mortality rate. After negative direct examination, first line investigation is a lateral soft tissue neck x-ray, however interpretation of these by doctors in training can be difficult and there can be misleading non-pathological calcification of the laryngeal framework.

Case Series: We present 3 cases of upper oesophageal obstruction secondary to dental plate ingestion. In all three cases a foreign body was not initially noted on lateral soft tissue x-ray but due to the high index of clinical suspicion, all three underwent intervention. Two required rigid oesophagoscopy and removal in theatre and the third tolerated removal under local anaesthetic using McGills forceps.

Discussion: The case series highlights the potential difficulty in identifying oesophageal foreign bodies lodged at the level of the cricopharyngeus. Inclusion of a radio-opaque marker on dental plates would allow for easy identification of dental foreign bodies and avoid unnecessary procedures on a vulnerable and often frail patient group. If there are no visible radiological signs, patients should still undergo rigid oesophagoscopy if there is a high index of clinical suspicion.
