AbstractThe 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 percent were removed per-orally, or by indirect laryngoscopy. Fifteen percent were removed using the fibreoptic nasopharyngoscope. Twelve percent 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.

AbstractBackgroundLateral neck radiographs are commonly used in the investigation and management of patients presenting with suspected fish bone impaction. The effectiveness of these is questioned, as many fish do not have radio-opaque bones.ObjectiveThis study evaluated the utility of lateral neck radiographs in the management of patients presenting with fish bones retained in the upper aerodigestive tract, with the creation of a treatment algorithm to guide further management.MethodsAn audit of practice was undertaken at the University Hospital of Southampton, identifying all patients admitted with potential fish bone impaction in the upper aerodigestive tract. Following analysis, a treatment algorithm was constructed for use by junior doctors.ResultsIn total, 34 per cent of patients with a normal radiograph were subsequently found to have a fish bone present under local or general anaesthetic assessment. The sensitivity of radiographs in the detection of fish bones was found to be 51.6 per cent.ConclusionLateral neck radiographs have limited value in the management of suspected fish bone impaction, and should only be used following detailed clinical examination of the upper aerodigestive tract.

Background Fish bones are common foreign bodies in the upper aero-digestive tract, but their clinical features in relation to fish species have not been confirmed. We aimed to clarify the clinical characteristics of fish-bone foreign bodies and their location and removal methods depending on the fish species. Study design Retrospective, observational, monocentric study. Methods From October 2015 to May 2020, 368 patients visited the Department of Otolaryngology-Head and Neck Surgery at Tohoku University Hospital complaining of dysphagia, sore throat, or pharyngeal discomfort after eating fish. We analyzed the patients’ sex and age distribution, foreign-body location, type of the fish, and the techniques used for removing the foreign body. Results Fish bones were confirmed in the upper aero-digestive tract in 270 cases (73.4%), of which 236 (87.4%) involved fish-bone foreign bodies in the mesopharynx. The most frequently involved site was the palatine tonsil (n = 170). Eel was the most frequently observed fish species (n = 39), followed by mackerel (n = 33), salmon (n = 33), horse mackerel (n = 30), and flounder (n = 30). Among the 240 cases in which the bones did not spontaneously dislocate, 109 (45.4%) were treated by endoscopic removal (103 cases) or surgery (6 cases). In pediatric cases (<12 years old), almost all fish bones were found in the mesopharynx (138/139, 99.3%), and 31 cases (22.3%) required endoscopic removal. Flounder fish bones were often lodged in the hypopharynx and esophagus (9/30, 30%), hindering spontaneous dislocation and frequently necessitating endoscopic or surgical removal (19/29, 65.5%). Conclusion The characteristics of fish-bone foreign bodies differed depending on the fish species. Flounder bones were often stuck in the hypopharynx and esophagus and were likely to require more invasive removal methods. Confirming the species of the fish could facilitate appropriate diagnosis and treatment of fish-bone foreign bodies.

Fish bones are one of the most common foreign bodies in the upper aero-digestive tract. The use of plain X-ray in identifying fish bones has questionable value. We believe that the knowledge of the type of the fish ingested improves the diagnostic value of the neck X-rays. This study was designed to evaluate the relative radio-densities of the bones of commonly eaten fish in the UK. Twenty-three species of fish were studied and their bones were grouped into three depending upon their ratio-densities. This information is expected to be useful in identifying fish bones while reading plain radiography.

Abstract Background Fish bones are the most common aerodigestive foreign bodies found in adults. Most cases of fish bone impaction improve after primary management by emergency physicians with a mirror laryngoscopy using a tongue depressor, before otolaryngologists perform a fiberoptic nasendoscopy. A computed tomography scan usually follows to determine the next step. Studies have recently been concerned about overdoses of radiation from computed tomography. However, clear algorithms remain unavailable for fish bone ingestion management to date. Methods A retrospective review was conducted on 180 patients who visited the emergency department with complaints of fish bone impaction between January 2017 and January 2019. Results A total of 81.6% of patients with fish bone impaction got symptomatic relief after primary management by emergency physicians and otolaryngologists. Out of 180 patients, 33 (18.3%) needed an endoscopic procedure due to persistent symptoms. Only one (0.56%) required an operation due to perforation. In the group failing primary management, the plain radiography of eight patients showed a positive finding and an esophagogastroscopy was done to remove the fish bones. Conclusion Lateral neck radiography is still beneficial to patients with fish bone ingestion failure from primary management. Positive lateral soft tissue radiography in cases with persistent symptoms post primary management may directly suggest esophagogastroscopy without confirmation from a computed tomography, unless complications are suspected. For patients aged below 40, following up on their conditions after post management radiography shows negative results may increase their safety.

Hydroxyapatite (HA) is produced from animal sources like bovine-sheep bones and from human sources with different techniques. Nowadays, it is very crucial utilizing higher valued products from waste materials. Especially, fish bones become major sources for HA production. We have used the waste bone of "Atlantic Bonito" (Sarda sarda), which is a very characteristic fish species. It lives through Atlantic Ocean, the Mediterranean Sea and up to the Black Sea, where it is regarded as a point commercial fish. In this study, the fish bones of "Atlantic Bonito" (Sarda sarda) were collected and cleaned from flesh and greasy parts with distilled boiling water. It was washed again with distilled water, dried and calcinated for 4 hours at 850 °C. Afterwards the material was analysed by X-ray diffraction (XRD) and scanning electron microscope (SEM). XRD analysis revealed the obtained bioceramic material is made of 66.7% HA and 33.3% TCP. The fish bone of “Atlantic Bonito” (Sarda sarda) can be easily trandformed to bioceramic material and it can be used in applications where partly resorbable and economic biomaterials with low carbon footprint needed.

Introduction. Foreign body stuck in the throat is a common emergency case, which can be removed by the endoscopic treatment. Fish bones are one of the common observed foreign bodies in the pharynx or cervical esophagus. Fish bones have a risk of damaging the mucosa when lodged in the upper digestive tract. Foreign bodies of fish bones located outside the laryngopharyngeal tissue are relatively unusual, and it is even more rare that they remain in the thyroid. It may cause local infection, abscess formation, large blood vessels rupture, and other serious life-threatening complications when the position of the fish bone migrates to the neck. We present a unique case of a 31-year-old woman in whom a fish bone was found in the thyroid. The fish bone had been removed successfully two months after the onset of symptoms. The relevant literature is reviewed and summarized.Case Presentation. A foreign body which is located in the neck area by swallowing is usually found in the emergency case. One of the commonest foreign bodies is the fish bone. The common presenting symptoms include foreign body (FB) sensation and or a sharp pain during swallowing. But we report a rare case in which a migratory fish bone stuck in the thyroid gland was found after 3 months. We retrieved previous literature and made a summary.Conclusions. Fish bones are not easy to be found as a foreign body. Surgeons should be aware that fish bones can become lodged in the thyroid gland. Combined with the history should be a wary fish bone to migrate to the case of the thyroid, to avoid misdiagnosis. To confirm the diagnosis, we can take ultrasound, computerized tomographic scanning (CT), and other tests.
