Aural foreign body removal: there is no one-size-fits-all method

Management of Foreign Bodies in the Ear Canal

Using the appropriate instruments and techniques for removing a foreign body from the external auditory canal facilitates the procedure and reduces the risk of complications. Most ear foreign bodies can be addressed on a nonurgent basis, but batteries and caustic materials warrant prompt removal. Referral to an otolaryngologist should be considered for difficult cases or after a failed attempt.

Comparison of Care Settings for Pediatric External Auditory Canal Foreign Bodies: A Meta-Analysis

OBJECTIVE

To compare the success and complication rates of pediatric external auditory canal foreign body (EAC FB) removal between Emergency Departments (ED), Primary Care Providers (PCP), and Otolaryngologists (ENT).

METHODS

PubMed, Scopus, and Embase were searched through January 13, 2022. Studies mentioning EAC FB removal success rates and types of healthcare settings were included. Pooled measures included abrasions/lacerations, TM perforations, and success rate stratified by healthcare setting.

RESULTS

Thirteen studies and 3891 patients were included in the meta-analysis. Most comparisons between EAC FB removal success rates for EDs versus PCPs versus ENTs were statistically significant. The highest FB removal success rate was in patients who presented to ENTs without previous removal attempts (92.9% [95% CI 84.6-98.2]). EDs had the lowest success rates (64.0% [95% CI 48.3-78.3]). For patients that had a previous attempt at FB removal, ENTs had a success rate of 64.1% [95% CI 42.0-83.5].

CONCLUSIONS

For ENTs treating pediatric EAC FB, removal success rates decrease if a different healthcare provider previously attempted EAC FB removal. This effect likely is due to decreased patient cooperativeness or increased FB complications (eg, canal edema and bleeding limiting visualization) after previous removal attempts. Individual institutions should identify conditions that increase EAC FB removal failure rates and necessitate ENT referral. Therefore, the communication and concerted efforts between EDs, PCPs, and ENTs are critical for the improved outcomes of pediatric EAC FBs.

Management of Live Insects in the External Auditory Canal: A Wilderness Perspective

A live insect within the external auditory canal is an unpleasant possibility during wilderness recreation. To our knowledge, no study has attempted to quantify the risk of this event occurring in the wilderness. However, such events anecdotally seem to occur with some regularity in a variety of climates. Most cases are benign, but a small subset of patients can develop complications including infection, hearing loss, and vestibular complaints related to the foreign body. In the emergency department or clinic, removal of the insect is a simple procedure in most circumstances; however, the material and expertise required for backcountry removal of the insect are often limited. With this consideration in mind, we offer a conservative approach to backcountry insect removal based on a selective review of the published literature on this topic. Where published data are lacking, we make recommendations based on anecdotal experience of the authors dealing with this condition in austere environments and in the emergency department. We recommend insect removal only if the patient is acutely symptomatic and the insect is visualized and graspable with the instrument used for removal. In any other circumstance, intervention should be deferred until definitive care is reached because of risks of complications associated with removal, including infection, bleeding, and tympanic membrane damage.

Adult Popillia japonica as an Otorhinolaryngologic Invasive Foreign Body in a Rural Area

Otorhinolaryngologic foreign bodies may be encountered in-office visits, the emergency department, and speciality consultations. These include food, toys, and other small items, are present in pediatric patients. Because patients may be asymptomatic and the insertion of the foreign body not observed, obtaining medical care may be delayed. Conversely, insects as foreign bodies, especially in the external ear canal, can cause a patient significant pain and distress, directing the patient to seek immediate care. Here, we present a case of an adult Japanese beetle (Popillia japonica) as a foreign body in the ear of a 14-year-old female. A review of otorhinolaryngologic foreign bodies is also discussed, with particular attention to the ear and rural location. This case highlights the potential for agricultural insects to act as invasive foreign bodies, especially in areas where they are known to be endemic pests and the consequences of delayed treatment.

Pediatric foreign bodies of the ear: A 10-year national analysis

OBJECTIVES

To estimate the incidence of emergency department visits for pediatric ear foreign bodies. To identify the most common items and their trends.

METHODS

The Nationwide Electronic Injury Surveillance System (NEISS) was queried for emergency department visits involving the diagnosis of foreign bodies in the ear including pinna and canal in children over the most recent 10-year span available. National incidence estimates and demographic data were extracted from the same database.

RESULTS

Ear foreign bodies in children made up an estimated total 446,819 ED visits nationwide over the past 10 years. The mean age was 7.2 ± 4.3 years old. The majority (55.6%, n = 248,531) of cases were female. The most common class of objects found was jewelry, primarily embedded earrings and beads, accounting for 55.5% visits, followed by paper products at 7.1%, pens and pencils at 4.1%, desk supplies (erasers) at 3.7%, BBs or pellets at 3.5%, and earplugs and earphones at 3%. Females were significantly more likely to have jewelry foreign bodies, and males were significantly more likely to have foreign bodies from all other categories other than first-aid supplies.

CONCLUSION

Foreign bodies of the ear are a common reason for emergency department visits in children, primarily jewelry, paper products, and desk supplies. Recognition of commonly encountered objects can aid in both speedier recognition of unknown objects, as well as guide patient counseling.

Clinical Characteristics of External Auditory Canal Foreign Bodies in Children and Adolescents

OBJECTIVES

Foreign bodies (FBs) in external auditory canal (EAC) can occur at any age but are especially common in children and adolescents. The aims of the study were to evaluate the clinical characteristics of EAC FBs in children and adolescents and to discuss their proper management.

METHODS

A retrospective medical chart review was performed on patients who were treated for EAC FBs in a tertiary referral center from January 2007 to December 2017. We investigated the parameters of age, sex, type of FB, sedation method, complications, and removal strategy.

RESULTS

Of 284 patients, 176 (62.0%) were male. Peak incidences were noted at the ages of 3 to 6 years and 17 to 18 years. The frequently observed FBs were insects, followed by air-gun pellets, cotton balls, marbles, and earrings. Forty-one (14.4%) EAC FBs were removed with the naked eye, while 243 (85.6%) were removed under microscope in the otolaryngology department. Of these patients, 23 (9.5%) were administered sedatives and 1 (4.1%) needed general anesthesia. During or after the removal procedure, 4 (15.5%) patients had complications of EAC abrasion or laceration (42, 14.8%), and tympanic membrane perforation (2, 0.7%).

CONCLUSIONS

External auditory canal FB showed a distinct characteristic of incidence regarding age, related to removal strategies. Characteristics of FB must be considered for safe removal.

Light-assisted removal of ear canal live insect-A noninvasive approach for first level responders

Physicians, working in the primary care setting and/or emergency departments, encounter more often patients of any age group with foreign bodies in the external auditory canal (EAC) and urgent removal is crucial to avoid complications. The condition is more commonly managed on an urgent basis if the foreign body is a live insect that is more agonizing for the patient. Foreign body removal is quite challenging but an essential skill for first-level responders and different approaches, each with its own pros and cons, are used for EAC foreign bodies removal. Herein, we report two cases that were managed safely by a noninvasive approach by using light illumination of EAC in complete darkness. The approach, not reported in the available literature, can be used as first-level management before opting another alternative, in settings where otolaryngologist services are not readily available.
