This post is based on a talk I gave for the London School of Paediatrics in June 2020, and will focus on foreign bodies in the nose and ear.  If you’d like to read about ingested foreign bodies, please read this, from Andrew Tagg.

 

Foreign bodies in the ear or nose

Children often present to the emergency department with something alien in their ear or nose. They’re usually in the pre-school age group and have been experimenting by sticking things in their various orifices. Most children can be found with a finger up their nose on a fairly regular basis, but sometimes other objects too. These can be among the more light-hearted of ED attendances, but only if you have some strategies to deal with them.

4-year-old George comes into your ED with his exasperated mother.  She explains that he’s been telling her he has a phone in his ear for the last 2 days. “Obviously he hasn’t”, she says, “but please would you just have a quick look so I can tell him to stop going on about it”. You have a quick look in his ear, and you see something blue in there.* How will you proceed?

 

General considerations to aid success

Preparation is key. This means preparing the child, and yourself, for the procedure.

Think of foreign body removal as a one-time offer. You’ll generally have only one good go at it, so preparation is everything. This means getting the right people involved, ideally a play specialist or someone else who’s only role is to distract and calm the child. Make sure they know what is going to happen if they are old enough to understand. If they are unable to keep still, position them appropriately on their parent’s lap or maybe wrapped in a blanket. Foreign body removal is generally not painful (or shouldn’t be) but for children who are able, nitrous oxide can be a useful aid for its anxiolytic properties in addition to distraction.

Prepare yourself. Make sure you use the right technique and equipment for the job. There are several options:

  

Kissing technique

This is a useful technique for removing FBs from the nose and works especially well for solid objects such as beads. Getting the parent on board with it and briefing them about the technique is key:

  • Sit the child sideways on the parent’s lap with one of the child’s arms tucked away under the parent’s arm
  • Brief the parent that you want them to cover the child’s mouth with their own while you occlude the unaffected nostril
  • Get the parent to deliver a short sharp breath and, hopefully, the FB will shoot out!

 

 

For parents who either can’t master the technique, or can’t face it, the same effect can be achieved with a bag-valve-mask: choose a mask that only covers the child’s mouth, and occlude the pop-off valve to increase the pressure. Ask a colleague to hold the mask and the unaffected nostril, while you squeeze the bag sharply.

 

Other useful tools and techniques

Head torch – this is a game-changer in the world of foreign body removal. It prevents you from having to try to hold a torch in your mouth while holding an ear in one hand and tool in the other.

Yankauer suction – good for removing objects with a smooth surface e.g. beads, polystyrene balls. Warn the child it’ll be noisy and let them hear it before you start so they don’t jump away.

 

 

Syringe and water – good for items that will float or disintegrate e.g. tissue, play-doh, polystyrene beads. Add a cut-down NG tube on the end to make a smaller nozzle. Fill with warm water (for comfort) and irrigate generously. 

 

 

Jobson Horne probe – useful to get behind objects in the ear canal that won’t come out with suction. In this case, it will only work if there’s a little gap and you can actually get behind it.

Wax hook – can be used to get behind foreign bodies, as above, or to hook into softer objects such as bits of tissue or peas. Make sure you don’t leave some behind with this method.

Crocodile forceps – helpful with small or softer objects or those with an uneven surface where there’s something to grab.  

 

 

TOP TIP: magnetize the shaft to make it easier to pick up metal FBs

Magnets – can be used by rubbing them down the side of the nostril to work a foreign body down and out.

TOP TIP: the magnets on name badges are often useful for this if you don’t have a store of magnets specifically for the purpose.

Cotton bud and glue – can be used to remove foreign bodies from the ear canal if they’re difficult to get behind or to grab.  Apply a drop of whatever tissue adhesive you use to the end of a cotton bud and hold it on the offending item for 30 seconds or so then pull out.  This requires a steady hand and a reasonably still child. Be aware that this method can lead to adherence of the offending item to the ear canal.

 

 

Foley catheter – pass it behind a foreign body in either the nose or ear, inflate the balloon and then pull out, bringing the piece of corn with it.

 

If at first, you don’t succeed… stop

Complications can arise from failed attempts at removal, especially those involving the ear canal. These can range from pain, bleeding, distress, and the loss of trust to rare, but severe, complications including middle ear damage, hearing loss, vertigo, facial nerve paralysis and meningitis (Dance et al., 2009). If an attempt isn’t going well, stop, re-group, and consider the options. It may be that referral or a different approach is required.

 

Or maybe, don’t even start

If there is minimal chance of success, either because the FB is deep, impacted, or ungrabbable, or the child is unable to co-operate for whatever reason, think twice before starting. It may be better to bring them back when you have play specialist support or to refer to ENT for specialist assistance.

You involve the play specialist and prepare George for removal of the foreign body in his ear.  Wearing your headtorch, you gently pull on his pinna and gently insert a pair of crocodile forceps into his ear canal and pull out… a teeny tiny toy phone!  Vindicated, George squares up to his mum: “I told you!”.
