Product Information

Before inserting the otoscope cone into the ear canal, the outer ear is inspected for any signs of disease that may relate to the patient's symptoms. For example, if the complaint is of ear pain, there may be evidence of an infection of the outer ear in the form of redness or slight swelling. Examination of the external auditory canal

This allows the eardrum to lie in its middle position and respond to sound vibration most efficiently.

The type and model of otoscope you use will always be determined by your specific requirements–whether you are a veterinarian, a paediatrician or an ENT specialist. Mobility aids: items such as wheelchairs and walking aids give an indication of the patient’s current mobility status. The patient may have vestibulocochlear nerve pathology causing both hearing and balance issues. Klaus D. Peter, Gummersbach, Germany. Adapted by Geeky Medics. Basal cell carcinoma.

Absence or distortion of the light reflex is associated with otitis media (due to bulging of the TM). Perforation Inspect the conchal bowl for signs of active infection such as erythema and purulent discharge. Palpation On the near chart, there is also an Amsler chart for assessing macular disease and a matching card if the patient is very young or having difficulty with expressive language.

Diseases which may be diagnosed by an otoscope include otitis media and otitis externa, infection of the middle and outer parts of the ear, respectively. Confirm the patient can hear the sound of the tuning fork and then ask them to tell you when they can no longer hear it.Retraction of the TM suggests reduced middle ear pressure, which is commonly caused by pharyngotympanic tube dysfunction secondary to upper respiratory tract infections and allergies. Light reflex Look for objects or equipment on or around the patient that may provide useful insights into their medical history and current clinical status:

Hold the otoscope like a pencil and rest your hand against the patient’s cheek for stability. This will prevent damage to the ear if there is sudden movement. Confirm the patient can hear the sound of the tuning fork and then ask them to tell you when they can no longer hear it Tympanosclerosis often develops secondary to otitis media or after the insertion of a tympanostomy tube. Final steps Ask the patient if they can now hear the sound again. If they can hear the sound, it suggests air conduction is better than bone conduction, which is what would be expected in a healthy individual (this is often confusingly referred to as a “Rinne’s positive” result).

The HEINE otoscopy compendium provides practical tips and gives an initial insight into typical clinical pictures. To alleviate some of these difficulties in performing a successful otoscopic examination, video-otoscopes have been introduced in recent years and studied for their efficacy in diagnosing ear conditions. Video otoscopes allow the provider to introduce a small camera into the patient’s external auditory canal to visualize the tympanic membrane. Research into the effectiveness of video-otoscopy suggests that this technique may be superior compared to conventional otoscopy in assessing pathological conditions of the tympanic membrane. [1] Causes of TM perforation include infection (e.g. otitis media with effusion), trauma (e.g. diving-related), cholesteatoma and insertion of tympanostomy tubes (also known as grommets). Many otoscopes used in doctors offices are wall-mounted while others are portable. Wall-mounted otoscopes are attached by a flexible power cord to a base, which serves to hold the otoscope when it's not in use and also serves as a source of electric power, being plugged into an electric outlet. Portable models are powered by batteries in the handle; these batteries are usually rechargeable and can be recharged from a base unit. Otoscopes are often sold with ophthalmoscopes as a diagnostic set.
