Flexible nasopharyngoscopy for fish bone removal from the pharynx.
The use of flexible nasopharyngoscopy with biopsy forceps for the removal of fish bones found in the oropharynx and hypopharynx is described. One hundred and sixty-eight patients with ingested fish bones in the upper aero-digestive tract were studied over a 12-month period. Of these, 73 per cent were removed per-orally, or by indirect laryngoscopy. Fifteen per cent were removed using the fibreoptic nasopharyngoscope. Twelve per cent required a general anaesthetic and rigid oesophagoscopy for removal of fish bones at or below the level of the cricopharyngeus muscle. The technique has proven to be quick, well tolerated and low in morbidity. It is invaluable in patients in whom indirect laryngoscopy is unsatisfactory.
