- Page 17 Process A practitioner typically asks questions to obtain the following information about the patient: Identification and demographics: name, age, ... The chief complaint - the major health problem or concern, and its time. History of the present illness - details about the complaints, enumerated in the chief complaint.
- Page 18 Case History Otoscopy Primary test Report Evaluation of Ear with a Otoscope The otoscopic exam is performed by gently pulling the auricle upward and backward. In children, the auricle should be pulled downward and backward. This process will move the acoustic meatus in line with the canal. Hold the otoscope like a pen/pencil and use the little finger area as a fulcrum.
- Page 19 Identify the pars tensa with its cone of light, the handle and short process of malleus, and the anterior and posterior folds of the pars flaccida and position of the malleus handle.. Examination of the ear canal and tympanic membrane The ear canal and tympanic membrane should then be examined.
- Page 20 The examination of the ear canal and tympanic membrane shall be conducted carefully and safely, taking into account the size, shape, orientation and condition of the ear canal and the presence of wax or foreign bodies. It shall also take into account that the bony portion of the ear canal is especially sensitive and its surrounding skin vulnerable to trauma.
- Page 21 Otoscopy Primary test Case History Report Evaluation of Hearing with a Tuning Fork There are three types of hearing loss: conductive, sensorineural, and mixed. Differentiation between sensory (cochlear) and neural (cranial nerve VIII) sensorineural hearing loss is important. Evaluating hearing with a tuning fork can be a useful clinical screening tool to differentiate between conductive and sensorineural hearing loss.
- Page 22 Weber tuning fork test The Weber tuning fork test may be performed with a 512-Hz fork. The stem of a vibrating tuning fork is placed on the head in the midline, and the patient is asked whether the tone is heard in both ears or in one ear better than in the other. A normal result is when the patient can hear the tuning fork tone in both ears equally.

- Page 28 3.7.7 Manual Air Conduction Testing Air conduction audiometry is used to establish a hearing threshold at different frequencies. The test can specify the AC loss but gives no information regarding any abnormality in the conductive mechanism or sensor neural mechanism. 3.7.8 Headphone Placement Remove eyeglasses and earrings if possible and position the headphones over the top of the head.
- Page 29 3.7.12 Threshold Determination using the Ascending Method Manual or reversed pulses may be used. If manual pulses are used, they should be at least one second in duration. 1) Present a tone which is 10dB lower than the threshold obtained during the familiarization procedure.

Audiometry Reports Contain: we make sure all our reports contain information which is meaningful to a lay person. Alongside this, we always have an eye on the fact that reports may often be read by specialists therefore we also make sure that all the technical information they may need is also present.
