[Fish bone in retropharyngeal treatment with transoral laser CO2 microsurgery: a case report]

Fish bones are the most common pharyngeal foreign bodies encountered in the ENT emergency. Many fish bones may be buried in the surrounding soft tissue of the pharynx and larynx. Any delayed treatment for these foreign bodies may cause catastrophic complications. We present a case of 51-year-old woman who had an ingested fish bone migrating to the retropharyngeal space. We used spiral Computed tomography scanning (CT, taken at intervals of 2mm) with dimensional reconstruction for the accurate location diagnosis and surgical planning. We treated successfully before any complication by transoral Laser CO2 microsurgery.
