Ear Canal Obstruction

(Foreign bodies in the ear)

A transfer of the ear canal by cerumen (ear wax), foreign objects or insects may cause itching, pain and a temporary conductive hearing loss. In the otoscopic examination, most obstruction causes can easily identify. Treatment consists of careful manual removal of the obstacle.

to be removed before and after the experiment, ear wax or a foreign body, the physician should consider carrying out a hearing test, if the necessary equipment is readily available. Hearing loss (compared to the unaffected ear), which does not improve after the removal of the obstruction, may suggest that the foreign body (or earlier attempts to remove him) has damaged the middle or inner ear. hearing deteriorated after removal of the obstruction, it may indicate damage, which are caused by the removal process itself. However, should the examiner who can not judge hearing formal, not postpone the elimination of the usual, easy to remove obstructions. By a tuning fork test in practice, the hearing status can also be documented.

Cerumen cerumen, which is pushed by cleaning trials of patients with swab deeper into the ear, can form a plug and clog the ear canal or press. Before passing it through an ear irrigation or directly removed, hardened wax with solvents such as hydrogen peroxide, carbamide peroxide, glycerin, triethanolamine, liquid docusate sodium or mineral oil should be softened. A longer-term application of such “softening” but can cause skin irritation or allergic reactions in the ear canal. The cerumen is a blunt curette or noose or a narrow rechtwinkeligem or hook. with a suction syringe (z. B. Baron, size 5 French) taken out of the ear canal. Proper lighting is essential. These methods are faster, safer and more comfortable for the patient as a rinse, which can not be generally recommended. Contraindicated are ear flushes in patients with otorrhoea or a tympanic membrane in the history; because by the cracks water could penetrate through the tympanic membrane into the middle ear and amplify a chronic otitis media and cause acute otitis media. Foreign body in the ear foreign body found in the canal is especially common in children, often small parts stuck while playing in the ears (such. As beads, erasers or beans). Sometimes a foreign object remains unnoticed until an inflammatory reaction with pain, itching, infection and foul-smelling purulent discharge is established. In general, foreign bodies, can seem easy to grip and remove (eg. As paper, an insect wing) with an alligator forceps by most doctors to be removed. However pliers tend to push round, smooth objects (eg., Beads, beans) deeper into the canal. Patients with these objects a referral to an otolaryngologist is necessary. A smooth rounded foreign bodies can be best with a small, blunt hook grasp from behind rolling out what should be done under the operational microscopic control by a specialist. Difficult medially of the isthmus foreign bodies located (at the transition between the bony and cartilaginous portion of the ear canal) may be without removing the sensitive ear canal, to hurt the eardrum or the ossicles. (.. Translator’s note .: As a rule, but all ear canal foreign body without eardrum injury can be removed; in children mask anesthesia is usually required.) Referral to an ENT specialist is also displayed in an uncooperative child requires sedation or failed attempts at the distance. Tips and Risks An ear irrigation is not advisable to remove ear wax or foreign bodies. Hygroscopic foreign objects (such as beans and other dry parts of plants) which swell in water are difficult to remove. If children do not keep still or be injured eardrum and ossicles in a more complicated removal, the interference with general anesthesia or deep sedation should be carried out. If an alleged foreign body starts to bleed during handling, further attempts should remove this one otolaryngologist be consulted and stopped immediately. can bleed a laceration of the “canal skin” see that the foreign body is actually a Mittelohrpolyp. Insects in the ear canal are particularly troublesome when they are still alive. To kill them, lidocaine gel is filled into the ear canal; which causes immediate improvement, and the motionless insect can then be removed with tweezers by sums up a wing or a leg.
