Professional Otoscope Auroscope with accessories from Sigma Lance

Product Information

Scarring of the TM is known as tympanosclerosis and can result in significant conductive hearing loss if it is extensive. Sensorineural hearing loss occurs due to dysfunction of the cochlea and/or vestibulocochlear nerve. Causes of sensorineural hearing loss include increasing age (presbycusis), excessive noise exposure, genetic mutations, viral infections (e.g. cytomegalovirus) and ototoxic agents (e.g. gentamicin). Ensure the light is working on the otoscope and apply a sterile speculum (the largest that will comfortably fit in the external auditory meatus).

The most commonly used otoscopes consist of a handle and a head. The head contains a light source and a simple low-power magnifying lens, typically around 8 diopters (3.00x Mag). The distal (front) end of the otoscope has an attachment for disposable plastic ear specula. The examiner first straightens the ear canal by pulling on the pinna (usually the earlobe, side or top) and then inserts the ear speculum side of the otoscope into the external ear. It is important to brace the hand holding the otoscope against the patient's head to avoid injury to the ear canal by placing the index finger or little finger against the head. The examiner can then look through a lens on the rear of the instrument and see inside the ear canal. In many models, the lens can be removed, which allows the examiner to insert instruments through the otoscope into the ear canal, such as for removing earwax. Most models also have an insertion point for a bulb capable of pushing air through the speculum which is called pneumatic otoscope. This puff of air allows an examiner to test the mobility of the tympanic membrane. Otoscopes are fitted with × 3 magnification that helps in zooming any foreign objects including wax in the ear. It also has a large viewing window that allows specialists to extensively assess the inner part of the ear. Besides, the fiber optic otoscope uses LED light to illuminate inside the ear for clarity. Proper diagnosis with regards to identification of objects is crucial in determining a possible solution to the affected ear. By carefully advancing the speculum down into the external auditory meatus you will see the external ear canal and tympanic membrane. 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. Conductive hearing loss occurs when sound is unable to effectively transfer at any point between the outer ear, external auditory canal, tympanic membrane and middle ear (ossicles). Causes of conductive hearing loss include excessive ear wax, otitis externa, otitis media, perforated tympanic membrane and otosclerosis.Klaus D. Peter, Gummersbach, Germany. Adapted by Geeky Medics.

Ask the patient which is their “better” ear and examine this one first (this can be useful for comparison). The HEINE otoscopy compendium provides practical tips and gives an initial insight into typical clinical pictures. Confirm the patient can hear the sound of the tuning fork and then ask them to tell you when they can no longer hear itMany 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. Select the light you require (e.g. varying levels of white light or blue light) using the grey switch and hold it close to your eye. an inflamed and swollen, narrowed canal, possibly with a discharge indicating infection ( otitis externa). The usual symptoms include itch, local discomfort, a discharge and often an unpleasant smell from the ear. By Michael Hawke MD. Adapted by Geeky Medics. Tympanic membrane perforation.

We would like to learn more about what you value in an otoscope, what you think of HEINE, who decides on a new otoscope and how – and for this we would like your support. Answering the questions will take about 5 minutes. 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.Advance the otoscope under direct vision. Be gentle with the otoscope and ensure movements are slow and considered otherwise you will cause discomfort. External auditory canal assessment

Normally the air pressure within the middle ear is the same as that in the outer ear. This allows the eardrum to lie in its middle position and respond to sound vibration most efficiently. An otoscope–also known as an ear magnifier, ear light or auriscope–is a medical instrument that is typically used to examine the eardrum and external ear canal. 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. Examination of the tympanic membrane and middle ear by otoscopic examination can help providers diagnose a wide variety of conditions, including acute otitis media, traumatic perforation of the tympanic membrane, and cholesteatoma. Delayed diagnosis of various pathologies of the ear can facilitate progression to more serious conditions, highlighting the importance of otoscopy. For example, untreated acute otitis media can advance to feared complications such as mastoiditis, brain abscesses, or meningitis.
