Foreign Body Removal in ENT: Ear and Nasal Foreign Bodies
A foreign body is an object or material present in the ear, nose or upper aerodigestive tract when it is not normally found there. It may be inserted deliberately, accidentally enter during play or work, or be retained after an injury. Safe management begins before an instrument is picked up: identify the site and object, assess airway and tissue risk, obtain a clear view, choose a method matched to the object, and decide whether removal is within the clinician's skill and setting. A button battery or paired magnet in the ear or nose is an emergency because tissue injury can progress quickly.
After studying this note, you should be able to identify common ear and nasal foreign bodies; recognise dangerous objects and airway red flags; take a focused history and examine safely; select an appropriate removal method; explain when to stop and refer; and document the procedure, findings and aftercare.
This is a clinical education guide, not a self-removal guide. Instrumentation, irrigation, suction, topical anaesthesia, restraint and sedation require appropriate training, consent, equipment and supervision. Never insert an instrument when the object cannot be seen, never make a blind sweep, and do not delay urgent referral for a battery or a threatened airway.
Plan the first attempt. The first well-prepared attempt is often the best opportunity for atraumatic removal. Poorly chosen or repeated attempts can push an object deeper, cause bleeding and swelling, reduce visibility, increase distress, or convert a simple procedure into a specialist case.
Batteries and airway compromise take priority. A button battery in the ear or nose needs immediate removal by a competent clinician or immediate specialist escalation if safe removal is not promptly possible. Suspected inhalation, choking, stridor or respiratory distress requires emergency airway care, not routine outpatient extraction.
Why foreign bodies matter in ENT
Foreign bodies are especially common in young children, who explore by putting small objects into body openings. Adults may present with a broken cotton-bud tip, retained material after ear cleaning, occupational debris or an insect. People with cognitive impairment, developmental delay or mental-health conditions may have an increased risk. The history may be incomplete, so examination and awareness of associated insertion sites are important.
Most visible objects in the anterior nose or outer ear canal can be considered for removal in an appropriately equipped setting by a clinician trained in the selected method. That does not mean every object should be removed by the first clinician who sees it. Location, shape, material, depth, patient cooperation and the possibility of injury determine whether to proceed or refer.
Common objects and their practical implications
Paper, cotton, foam, plastic or a visible piece of toy may be graspable with forceps when there is enough room to approach it without pushing it deeper. Fragile cotton or paper can fragment if squeezed too hard.
Beads, peas, seeds or small balls may be difficult to grasp. Forceps can make a smooth object slip medially. A suitable hook, suction technique or another method that gets beyond the object may work better, but deep or impacted objects need experienced assessment.
Beans, seeds, nuts and other vegetable matter may swell when wet. Avoid ear irrigation for an object that can expand. Organic material left in place can provoke inflammation or infection.
Button batteries can cause chemical and electrical injury; magnets can cause pressure injury, particularly when more than one magnet traps tissue between them. Arrange immediate removal or urgent specialist support. Do not irrigate these objects.
A live insect can cause considerable pain and movement. A trained clinician may first immobilise or kill it with an appropriate agent when the tympanic membrane is known or reasonably believed to be intact, then remove it under direct vision. Do not pour hot liquid or an unselected substance into the ear.
First priorities: triage before examination
1. Check airway, breathing and circulation
Ask whether the object may have been inhaled or swallowed as well as inserted into the ear or nose. Look immediately for choking, ineffective cough, stridor, drooling, voice change, increased work of breathing, cyanosis, reduced air entry or altered consciousness. If any of these are present, call for emergency assistance and manage according to the local airway and foreign-body protocol. Do not delay for a detailed ear or nasal examination.
2. Identify a hazardous object
Ask specifically whether the object could be a button battery, magnet, sharp item or chemical material. Clarify whether more than one magnet may be present. A nasal button battery can rapidly damage the septum and adjacent mucosa; an ear battery can damage the canal and tympanic membrane. Immediate removal by a clinician competent in the procedure is required; if the object cannot be removed promptly and safely, arrange immediate ENT or emergency referral.
3. Look for trauma or complications
Severe pain, active bleeding, significant swelling, purulent or foul discharge, fever, vertigo, new hearing loss, suspected tympanic membrane injury, facial trauma, a deeply placed or impacted object, or a failed prior attempt raises the risk. Stabilise urgent problems and obtain senior or ENT support before further manipulation.
- Airway compromise, suspected inhalation, stridor or respiratory distress.
- Button battery in the ear or nose, or a hazardous magnet configuration.
- Sharp or penetrating object, major trauma, uncontrolled bleeding or suspected perforation.
- Object beyond safe reach, not visible, firmly impacted or close to the tympanic membrane.
- Repeated unsuccessful attempts, significant injury or a patient who cannot be safely stabilised.
- Do not use blind probing, forceps or finger sweeps.
- Do not irrigate an ear when the eardrum may be perforated or the object is a battery, magnet, seed or other swellable material.
- Do not keep repeating an unsuccessful method after the view worsens, bleeding starts or the patient becomes distressed.
- Do not send a battery home to await routine clinic review.
Focused history and examination
History
- What and where: Ask what the object is, how many may be present, when and how it entered, and whether there is any possibility of a battery, magnet, sharp object or organic material.
- Symptoms: Ask about pain, blockage, hearing change, tinnitus, dizziness, nasal obstruction, unilateral discharge, bleeding, sneezing, cough, choking, fever and breathing difficulty.
- Previous attempts: Find out what has already been tried, by whom, with which instrument or fluid, and whether the object moved or the patient developed pain or bleeding.
- Patient factors: Consider age, developmental stage, communication needs, sensory distress, medical conditions, medications affecting bleeding, allergies and the patient's ability to keep still.
- Associated insertion: In children, ask about and examine other likely sites when clinically appropriate. A child with one foreign body may have inserted another.
Examination
Explain the examination, obtain consent and position the patient so that the head is supported. Use good light, appropriate magnification and the right-size speculum. Inspect the pinna and accessible ear canal or the anterior nasal cavity before touching the object. Record its site, size, material, orientation, mobility and depth. Look for swelling, discharge, bleeding, abrasion and any view of the tympanic membrane. In the nose, note which side is involved, whether the item is anterior or posterior, and the condition of the surrounding mucosa.
Document pre-existing injury before starting. If the object cannot be confidently distinguished from normal anatomy, such as a turbinate, polyp or canal lesion, do not assume that it is a foreign body. Reassess the diagnosis and seek help.
Decide whether an attempt is appropriate
The object is clearly visible, accessible and non-hazardous; the patient can be positioned safely and is sufficiently cooperative; the operator has the necessary training and equipment; and there is a clear plan for the chosen technique and for stopping.
The object is deep, impacted, posterior, sharp, hazardous or difficult to see; the eardrum is obscured and irrigation is being considered; previous attempts have failed; the patient cannot remain still; or the required magnification, suction, anaesthesia or rescue support is unavailable.
Foreign bodies of the external ear
Objects in the external auditory canal may be asymptomatic or cause pain, fullness, reduced hearing, tinnitus, cough from canal stimulation, discharge or bleeding. A long-retained object may be surrounded by wax, swelling or infection. Children may be unable or unwilling to describe the event, and a caregiver may only notice sudden hearing change or persistent ear discomfort.
Choose the method to fit the object
Useful for objects that can be securely grasped, such as visible paper, cotton or a soft irregular object. Use controlled traction under direct vision. Avoid squeezing a smooth rounded object if this is likely to make it slip deeper.
May be suitable for a firm object when the tip can be passed beyond it under direct visualisation and the canal anatomy allows a safe path. Do not advance blindly or lever against the canal wall or tympanic membrane.
May help with a smooth object when an appropriate suction tip can obtain a seal, or with loose fragments. It requires suitable equipment and a stable view. Avoid using suction if the object is too deep, the patient cannot remain still or the operator cannot see the tip and object clearly.
Consider only for selected loose, non-swelling objects when the tympanic membrane is intact and irrigation is otherwise safe under local guidance. Use an appropriate low-pressure technique by a trained clinician. Avoid irrigation for batteries, magnets, seeds or other swellable materials, and whenever perforation or previous ear surgery is possible.
Safe approach to ear removal
- Prepare: Explain the plan, obtain consent, agree on a pause signal, gather the correct equipment and arrange assistance to support the patient's head if needed. Ensure that the patient is seated or positioned securely.
- Optimise the view: Use otoscopy and magnification or a headlight when available. Gently straighten the canal by moving the pinna; the direction varies with age. Keep the instrument tip and object in view throughout.
- Make one deliberate attempt: Use the technique chosen for the object's shape and material. Work slowly and avoid pushing the object medially. Stop if the object moves deeper, the view is lost, pain becomes significant, or bleeding or dizziness occurs.
- Inspect again: Confirm that the object is fully removed and intact. Re-examine the canal and tympanic membrane when visible. Look for retained fragments, laceration, bleeding, swelling or perforation.
- Escalate when needed: If the first controlled attempt fails or the object becomes less accessible, stop and arrange ENT review rather than repeating an increasingly difficult attempt.
Special situation: an insect in the ear
A live insect may cause sudden severe distress. Keep the patient calm and avoid inserting instruments while it is moving. A trained clinician may immobilise or kill the insect with an appropriate topical method before extraction, provided that a perforated tympanic membrane is not suspected and the selected agent is suitable. Oil, when used, must be warm rather than hot and should be reserved for an insect; it is not a general-purpose method for other ear objects. Remove visible remains under direct vision and examine the canal and eardrum afterward.
Foreign bodies of the nose
Nasal foreign bodies are most frequent in young children. Common items include beads, paper, cotton, small toy parts, seeds, beans, food and occasionally batteries or magnets. The object is often in the front of the nasal cavity. A child may deny insertion or be unable to report it. Consider a nasal foreign body when there is persistent unilateral foul-smelling, blood-stained or purulent discharge, unilateral obstruction, local pain or recurrent epistaxis.
Examination and decision to remove
Assess breathing first. With the patient upright and the head supported, use a directed light and a nasal speculum if trained to do so. Inspect the anterior cavity without advancing an instrument toward an unseen object. Determine whether it is visible and reachable, whether the mucosa is swollen or bleeding, and whether it is a battery, magnet, sharp item or potentially aspiratable object. If it is posterior, difficult to visualise, impacted in swollen tissue, or beyond the operator's safe reach, seek ENT support.
Methods for selected anterior nasal objects
For a cooperative patient with a suitable anterior object, ask them to gently blow the affected side while the other nostril is occluded. Avoid forceful repeated attempts, especially if the object is sharp, a battery or magnet, or could be displaced backward.
A clinician may consider a positive-pressure method, including the parent or caregiver “kiss” technique, for an appropriate child with a visible, non-hazardous nasal object. Explain it fully and use it only when the patient is stable and the method is within local practice. Do not use it for a battery, a sharp object, significant respiratory symptoms or an object likely to be displaced into the airway.
Use an instrument only when the object is seen and the instrument can be placed safely. Grasp an object that is genuinely graspable. For a smooth object, a trained clinician may pass a blunt hook beyond it under direct vision and draw it forward. Do not pinch a smooth bead in a way that pushes it posteriorly.
These are options for selected objects when the operator has the relevant equipment and experience. They should not be advanced blindly or used when the patient cannot be kept still or the posterior airway risk is high.
Safe approach to nasal removal
- Position the patient upright with the head supported and explain the need to remain still. Obtain consent and arrange an assistant when needed.
- Use directed light and the appropriate nasal speculum to establish a clear view. Gentle suction may clear secretions if it can be done without moving the object backward.
- Choose the least traumatic method that is likely to succeed on the first attempt. Keep the object visible and work from an angle that brings it forward, not toward the nasopharynx.
- Stop for significant pain, bleeding, loss of the view, posterior displacement, patient movement or an unsuccessful controlled attempt.
- After removal, inspect the nasal cavity again for a second object, fragments, mucosal injury or ongoing bleeding. Give aftercare instructions and follow-up based on the findings.
Batteries and magnets are exceptions to routine outpatient technique. A nasal battery or hazardous magnet requires immediate removal by a competent clinician and urgent ENT or emergency support if safe prompt removal is not possible. Do not wait for inflammation or discharge to develop.
Throat, pharyngeal and inhaled foreign bodies
Foreign bodies in the pharynx or larynx may threaten swallowing or breathing. Choking, stridor, drooling, inability to swallow secretions, voice change, persistent cough, unilateral wheeze or sudden respiratory symptoms after eating or playing should raise concern for an airway or swallowed foreign body. A normal initial examination or chest radiograph does not reliably exclude an inhaled object.
Follow emergency airway and choking protocols and obtain urgent senior, anaesthetic and ENT support as indicated. Do not perform blind finger sweeps, and do not make a routine bedside attempt to retrieve an object that is not directly visible and safely accessible. A sharp or impacted object in the pharynx, suspected oesophageal impaction, button battery ingestion or respiratory compromise requires urgent specialist assessment.
- Stridor, noisy breathing, severe breathlessness or cyanosis.
- Weak or ineffective cough, inability to speak or sudden collapse.
- Drooling, inability to swallow saliva, altered voice or rapidly worsening distress.
- Persistent unilateral wheeze or reduced air entry after a choking episode.
Activate emergency help, assess airway and breathing, and use the age-appropriate local choking and resuscitation pathway. If the patient is stable but aspiration or oesophageal impaction remains possible, arrange urgent evaluation. Do not let ear or nasal removal delay airway assessment.
Children, cooperation and procedural safety
Children are at higher risk of insertion and may move suddenly when frightened or in pain. Before proceeding, assess whether the child can understand and cooperate, whether a caregiver can provide reassurance, and whether an assistant can safely support positioning. Use simple age-appropriate explanations and demonstrate equipment outside the body. Avoid forceful restraint whenever possible; restraint can be distressing and does not replace adequate training, a clear view or a safe technique.
If the child cannot remain still enough for safe removal, stop and arrange a setting with appropriate paediatric and ENT support. Sedation or general anaesthesia is a clinical decision requiring trained staff, monitoring, consent and rescue capability. Do not improvise sedation in a room without the necessary personnel and equipment.
Infection prevention and equipment
- Perform hand hygiene and use personal protective equipment appropriate to expected exposure and local policy.
- Check that the otoscope, speculum, light, suction and selected instruments are clean, functional and appropriate for the patient.
- Use single-use items once and reprocess reusable instruments according to manufacturer instructions and facility policy.
- Protect the patient's clothing and have tissues, a receiver and clinical waste disposal available where appropriate.
- Ensure that emergency assistance and referral pathways are accessible before starting a high-risk procedure.
Complications and aftercare
Potential complications include abrasion or laceration of the ear canal or nasal mucosa, bleeding, pain, swelling, infection, retained fragments, tympanic membrane perforation, hearing change, object displacement, aspiration and, rarely, injury to deeper structures. Risk increases when the object is deep or impacted, the patient moves, visibility is poor, or multiple attempts are made.
After removal
- Confirm completeness: Inspect the site again and confirm that the object is intact or identify any missing fragment. In the ear, reassess the canal and tympanic membrane when visible. In the nose, check both the affected side and the opposite side when appropriate.
- Reassess symptoms: Ask about pain, dizziness, hearing change, breathing, swallowing and ongoing bleeding. Repeat a simple hearing check if one was done before an ear procedure and the patient can cooperate.
- Treat injury according to findings: Minor superficial irritation may need observation and advice only. Suspected tympanic membrane injury, significant mucosal damage, persistent bleeding, retained fragments or infection needs senior review and appropriate follow-up.
- Avoid routine medication without an indication: Antibiotics are not automatically needed after uncomplicated foreign-body removal. Prescribe or refer according to documented infection, injury, patient risk and local guidance.
- Give return precautions: Advise prompt review for increasing pain, fever, foul discharge, persistent bleeding, new hearing loss, dizziness, breathing difficulty or recurrence of the obstruction.
Documentation checklist
Record site, suspected object and material, onset, symptoms, previous attempts, relevant risk factors, baseline injury, consent, examination and reason for choosing removal or referral.
Record operator and supervisor, method, equipment, patient position and cooperation, number of attempts, tolerance, whether the object was removed intact, and any complication or reason for stopping.
Record the repeat examination, eardrum or mucosal findings, symptom reassessment, treatment, advice, safety-net instructions, referral decision and follow-up plan.
Quick comparison: ear and nasal foreign bodies
- Common clues: pain, blockage, reduced hearing, tinnitus, discharge or bleeding.
- Choose a method based on shape, material, depth and tympanic membrane risk.
- Avoid irrigation for batteries, magnets, swellable objects or possible perforation.
- Refer deep, impacted, hazardous or repeatedly unsuccessful cases.
- Common clues: unilateral obstruction, foul-smelling discharge, bleeding or local pain.
- Most visible anterior objects are considered for careful removal by a trained clinician.
- Avoid blind probing or pushing a smooth object toward the nasopharynx.
- Remove batteries and hazardous magnets immediately; refer when posterior or difficult.
Key examination points
- Assess airway and hazardous objects first. A battery, magnet or suspected inhaled foreign body changes the urgency and setting of care.
- See the object before instrumenting. Poor visibility is a reason to improve the view or refer, not to probe blindly.
- Match technique to material and anatomy. A graspable object, a smooth bead, a seed and a moving insect do not call for the same method.
- Protect the first attempt. Explain, position, prepare and set a stopping point before beginning.
- Re-examine and document. Confirm complete removal, look for injury and provide safety-net advice.
