A foreign body is a rare cause of parotid gland obstructive sialadenitis; intra-oral penetration via Stensen's duct is unusual. The relatively recent introduction of interventional sialendoscopy to treat obstructive sialadenitis has allowed surgeons to adopt a gland-sparing approach by means of miniaturised endoscopes and instruments. However, unusual anatomy or pathological conditions can give rise to a risk of intraductal rupture that may lead to a subsequent iatrogenic foreign body.

This paper describes the case of a patient with a 4 mm stone engaged by a broken wire basket stuck in a secondary branch of Stensen's duct.

The iatrogenic foreign body was successfully retrieved by means of sialendoscopy-assisted transfacial surgery.

This is the first reported case of an intraductal rupture of a miniaturised device during interventional sialendoscopy successfully resolved by means of combined endoscopy and external surgery. This proved to be an effective method of rescuing a foreign body stuck in Stensen's duct.

There has been a surge in the popularity of loom bands amongst children in recent months. These small rubber bands, which can be woven together to make colourful bracelets and necklaces, have become the world's most popular toy. Foreign bodies in paediatric nasal and aural cavities are a common presentation to ENT units across the country. Whilst most are removed without incident, foreign bodies in nasal passages represent a potential risk for inhalation, leading to airway obstruction.

This paper reports a case series of four paediatric patients who presented with a loom band associated foreign body in the nose over a 7-day period at a district general hospital in Scotland.

Although the four cases presented were resolved without the need for general anaesthetic, the ever-soaring prevalence and popularity of loom bands necessitates a degree of caution and vigilance from parents, retailers and manufacturers alike. We believe there is an urgent need for greater public awareness of their potential hazards.

To describe a case of unwitnessed lithium ion disc battery ingestion, with a review of radiology findings and current best practice management.

A three-year-old girl presented following ingestion of a foreign body, which her four-year-old brother claimed was a one pound coin. The patient was managed non-urgently and transferred for specialist ENT assessment 6 hours following the initial ingestion, with no evidence of airway compromise. A corroded battery was removed from the level of the cricopharyngeus after 8 hours, with an associated circumferential mucosal burn.

There is increasing concern regarding the acknowledged rising incidence of lithium ion disc battery ingestion. The lack of a high index of suspicion and the inability to recognise subtleties on imaging may lead to suboptimal management with a higher degree of unnecessary immediate and delayed morbidity. The recently published American Academy of Pediatrics Guidelines may guide the approach to managing battery ingestions.

Foreign bodies in the transnasal ethmoido-sphenoidal sinus are uncommon. We present a case of unilateral rhinorrhoea caused by a foreign body which had been lodged in the ethmoido-sphenoidal sinus for 38 years.

A 40-year-old woman presented with unilateral rhinorrhoea. Computed tomography showed a foreign body located in the right ethmoido-sphenoidal sinus, with a defect of the lamina papyracea and the ethmoid roof. The endonasal approach did not permit extraction of the foreign body. A combined approach allowed the extraction of a pen cap, and the defect of the ethmoid roof was rebuilt.

Despite its limitations, the endonasal approach remains the treatment of first choice for osteo-meningeal defects, because of its minimal invasiveness and high success rate. However, in the presented case a combined approach was needed.

Intranasal teeth are uncommon. Causes include trauma, infection, anatomical malformations and genetic factors. They present mainly in children, and many are asymptomatic.

This report describes the finding of a tooth that had been displaced into the nasal cavity in a six-year-old girl. The history, clinical examination, findings and operative treatment are described.

The child presented with nasal symptoms. Examination revealed a tooth in the right nasal cavity, confirmed by a lateral cephalogram radiograph. It was extracted under general anaesthesia. At follow up, the child was asymptomatic.

This is an unusual case of a child presenting with an intranasal tooth and nasal symptoms following trauma a number of years earlier. The child underwent extraction of the tooth, and recovered well without any complications.

The objective of this study was to describe our experience removing esophageal coins from children in a tertiary care pediatric emergency department over a 4-year period.

We retrospectively reviewed a continuous quality improvement data set spanning October 1, 2004, through September 30, 2008.

In 96 of 101 cases (95%), emergency physicians successfully retrieved the coin. The median age of the children was 19 months (interquartile range [IQR] 13–43 months; range 4 months–12.8 years). The median time to removal of coin from initiation of intubation was 8 minutes (IQR 4–14 minutes; range 1–60 minutes). Coins were extracted using forceps only in 56 cases, whereas forceps and a Foley catheter were used in the remainder. Succinylcholine and etomidate were used in almost all cases for rapid sequence intubation prior to coin removal. Complications were identified in 46 cases: minor bleeding (13), lip laceration (7), multiple attempts (5), hypoxia (3), accidental extubation (3), dental injuries (3), bradycardia (2), coin advanced (1), right main-stem bronchus intubation (1), and other (8).

Emergency physicians successfully removed esophageal coins following rapid sequence intubation in most cases. Our approach may be considered for the management of pediatric esophageal coins, particularly in an academic pediatric emergency department.

Nasopharyngeal foreign bodies are relatively uncommon, compared with other aerodigestive sites. They may mimic a lower airway location, or may be coughed up into the nasopharynx prior to endoscopic evaluation.

To describe our experience with nasopharyngeal foreign bodies mimicking a more distal airway location.

Case series from a tertiary referral children's hospital.

We present a series of four children who were initially thought to have a lower aerodigestive tract foreign body (three respiratory, one oesophageal), but who were finally diagnosed with nasopharyngeal foreign body. The concept of panendoscopy at all foreign body removals is suggested as a means to avoid a missed nasopharyngeal foreign body.

Although nasopharyngeal foreign bodies are uncommon, their rare ability to mimic distal sites mandates a thorough endoscopic approach to ensure that all sites (i.e. larynx, lungs, oesophagus and nasopharynx) are evaluated endoscopically.

Virtual bronchoscopy is a noninvasive technique which provides an intraluminal view of the tracheobronchial tree. This study aimed to evaluate this technique in comparison with rigid bronchoscopy, in paediatric patients with tracheobronchial foreign bodies undetected by plain chest radiography.

Plain chest radiography was initially performed in 40 children with suspected foreign body aspiration. Computed tomography virtual bronchoscopy was performed in the 20 in whom chest radiography appeared normal. Virtual bronchoscopic images were obtained. All patients underwent rigid bronchoscopy performed by an otolaryngologist blinded to the computed tomography virtual bronchoscopy findings, within 24 hours. Virtual bronchoscopic findings were then compared with the results of rigid bronchoscopy.

In 12 patients, foreign bodies detected by virtual bronchoscopy were confirmed by rigid bronchoscopy. In one case, a mucous plug was perceived as a foreign body on virtual bronchoscopy. In another case, a minute foreign body was missed on virtual bronchoscopy. The following parameters were calculated: sensitivity, 92.3 per cent; specificity, 85.7 per cent; validity, 90 per cent; positive likelihood ratio, 6.45; and negative likelihood ratio, 0.089.

In the presence of a positive clinical diagnosis and negative chest radiography, computed tomography virtual bronchoscopy must be considered in all cases of tracheobronchial foreign body aspiration, in order to avoid needless rigid bronchoscopy. Computed tomography virtual bronchoscopy is particularly useful in screening cases of occult foreign body aspiration, as it has high sensitivity, specificity and validity.

To report an unusual observation whereby hearing was improved by insertion of cotton wool onto a retracted tympanic membrane, and to explore potential explanations for this.

We report the case of a 56-year-old woman with a severe mixed hearing loss who was noted to have a significant improvement in her hearing using a technique shown to her many years ago by a Russian physician. Upon application of a moist piece of cotton wool, gains of up to 40 dB were observed. This was associated with a significant subjective improvement in hearing. We discuss potential mechanisms for this effect, including amplification, a baffle effect and phase differences.

The mechanism of the hearing improvement observed in this case is unknown, but is likely to be related to sound amplification from the relatively large surface area of the cotton wool to the smaller oval window.

To demonstrate the importance of a detailed history when assessing patients with a repeated pattern of foreign body ingestion.

A 19-year-old woman presented to our department following accidental ingestion of a teaspoon. On further questioning, she admitted to a habit of binge-eating followed by self-induced vomiting, in order to avoid weight gain; she blamed this behaviour on a stressful relationship with her partner. She also had one previous episode of accidental ingestion of a plastic spoon, which had been removed by oesophagogastroduodenoscopy. The patient underwent an uneventful rigid oesophagoscopy and foreign body removal. During post-operative recovery, she admitted that she had suffered for years with bulimia and anorexia nervosa. She was discharged home after appropriate psychiatric counselling, and follow up was arranged.

Oesophageal foreign bodies are commonly encountered in otolaryngology practice. Such circumstances are often compounded by pre-existing psychiatric problems such as bulimia and/or anorexia nervosa. Patients with bulimia may often present with a very similar pattern of multiple episodes of ingestion of large foreign bodies. Identification of this eating disorder (especially when there is a recurrent history of large, accidentally ingested foreign bodies) and prompt psychiatric referral is essential for efficient long-term management of this condition.
