1. Foreign Body in ENT
DR O.A OPADOTUN
Babcock University Teaching Hospital
2. Definition
• An object is considered a "foreign body" if the object is in a location in
the body where it does not belong.
• Most airway foreign body aspirations occur in children younger than
15 years.
• Children aged 1-3 years are the most susceptible
4. Risk factors
• Age: commoner in pediatrics, esp between 1-5years.
• Adults with mental retardation
• Time of the year, commoner during holiday periods when children are
free to play around
5. Principle of foreign body removal
• Adequate patient exposure
• Patient must be well relaxed
• Adequate lighting
• Adequate skill
13. Battery
• result in severe destruction of the nasal septum.
• These are composed of various types of heavy
metals: mercury, zinc, silver, nickel, cadmium,
and lithium.
• Liberation of these substances
cause various types of lesions depending on the localisation,
• it causes intense local tissue reaction and liquefaction necrosis.
• As a result they can cause septal perforations, synechiae, constriction,
and stenosis of the nasal cavity.
14. Consequences
• Inert Foreign body
• Infection and inflammation of
mucous membrane
• Granulation tissue formation
and ulceration of mucosa
• Necrosis of bone or cartilage
• Vegetable foreign body
• Absorb water and swell
• evoke brisk inflammatory
response
16. Local examination
• Main diagnostic tool
• Object mostly found beneath
inferior turbinate or anterior
to middle turbinate
• Erythema ,edema
• Bleeding ,fetid nasal discharge
• Visualize T.M for acute otitis
media
• Assess for sinusitis
19. • POSITIVE PRESSURE TECHNIQUE:
• Tell the kid that parent is going to give them a kiss
• Instruct the parent to form a good seal on the mouth and then
• blow into mouth while occluding unaffected nostril
• It has a very low risk of barotrauma (<60mm hg ) , similar to a sneeze
20. • Child is restrained in upright position
• Add few drops of nasal decongestant
• Proper suctioning to visualise FB
• Curved hook is passed beyond FB
• And gradually drawn forward and removed
completely
21. Using Fogarthy catheter
• Ensure that balloon is intact
• Catheter is placed beyond the foreign body
• Balloon is then inflated Catheter is withdrawn
• through the anterior nares pulling the foreign body
22. Indication for GA
• Uncooperative and very apprehensive patients
• If troublesome bleeding is anticipated
• If the FB is posteriorly placed with a risk of pushing it back in to
nasopharynx
• If a foreign body is strongly suspected but cannot be seen in anterior
rhinoscopy
23. Removal under GA
• Patient is anaesthetised with cuffed ET tube
• Pharyngeal pack placed
• If FB is placed posteriorly , patient positioned in rose position and
mouth gag applied.
• Palate is generally retracted with a catheter which is placed through
unaffected nasal cavity
• FB is pushed from anterior nares in to the nasopharynx
• and pick up with foreps
24. Laryngeal foreign bodies
• Laryngeal foreign bodies usually cause complete or partial airway
obstruction.
25. • Young children are susceptible because:
• They lack molars for proper grinding of food.
• They tend to be running or playing at the time of aspiration.
• They tend to put objects in their mouth more frequently.
• They lack coordination of swallowing and glottic closure
26. • Food items are aspirated most commonly;
• Nuts or small food particles are the most frequently aspirated food
• After foreign body aspiration occurs, the foreign body can settle into 3
anatomic sites
• The larynx, trachea, or bronchus
30. Tracheobrochoncial foreign body
• The main symptoms are
• episodes of coughing,
• intermittent or continuous dyspnea with
• cyanosis, pain
• Intermittent hoarseness
31. Site
• This depends on the size
• Shape of the foreign body.
• The most common site is the right main
bronchus because of its straighter angle
of origin from the trachea
32. • If the foreign body is retained for a longer period the following can
occur depending on the
• type of foreign body and duration:
1. accumulation of secretions;
2. tracheitis or bronchitis with edema,
3. swelling, and granulations;
4. bleeding and bloodstained secretions;
5. partial obstruction of the lower airway or emphysema;
6. atelectasis or overinflation of the poststenotic part of the lung.
