1Department of Otorhinolaryngology, The First Affiliated Hospital of Sun Yat-sen University, Guangzhou, China.
Background:
Ingested foreign bodies fully embedded in retropharyngeal space present a unique challenge, as they can be difficult to locate and visualize via classic transoral laryngoscopy or the transcervical approach.
Methods:
We retrieved a complete extraluminal chicken bone located in the patient's retropharyngeal space at the level of the C4-C5 spine through a well-designed transcervical approach with a combination of image-guided neck navigation.
Conclusion:
A combined use of image-guided neck navigation and a dedicated transcervical approach for location of a foreign body in the retropharyngeal space is practical and available for clinical application.
