Behandlung verschluckter zahnprothesen: Erfahrungen mit 34 patienten

Background: Swallowed dentures can present with upper aerodigestive tract obstruction needing urgent intervention. Removing such an ingested denture can prove challenging and needs careful planning. Aim: To share our experience of managing patients with a swallowed denture focusing on the practical aspects of denture removal along with relevant literature review. We aim to raise a public health message on the safety aspect of usage of dentures.

Subjects and methods: A retrospective analysis of the patients managed by our team in the ENT department at two hospitals in Scotland, over 10 years (2009–2019), who were found to have swallowed a denture. Data on demographics, clinical history, examination findings and management of patients were collected and analysed using Microsoft Excel.

Results: A total of 34 patients were admitted with a swallowed denture, of which 24 (71%) were male and 10 (29%) were female. The mean age was 60 years (range 17–83). Of the 34 patients, 2 had a feeling of something stuck in the throat but were able to eat and drink; the rest of the patients complained about dysphagia and pain in the throat, with 2 patients also showing signs of respiratory distress. Twenty-four (71%) patients required denture removal under general anaesthetic in the theatre; 20 (59%) by rigid oesophagoscopy, 1 with tracheostomy (3%), 1 with (3%) laparoscopy and gastrostomy, and 2 (6%) with external neck exploration. Seven (20%) patients were taken to the theatre and the denture was removed with Magill forceps under light sedation using intubating laryngoscope or video laryngoscope. In 1 patient (3%), the denture material was successfully removed under flexible pharyngo-laryngoscopy guidance in the clinic without sedation. The final 2 (6%) patients were reassured as no foreign body was seen on flexible laryngoscopy.

Conclusion: In the absence of a clear evidence of denture ingestion, a detailed history and examination are needed to identify this serious pathology. Once confirmed, the ingested denture should be removed as soon as possible to minimize the risk of serious complications.
