<unk>  or otalgia maybe it is a<unk>  that originates outside the ear or the<unk>  that originates from the ear, and the etiology can be difficult to establish because of the complex innervation of the ear. Branches of the fifth, seventh, ninth, and tenth cranial nerve along with cervical nerves 1, 2, and 3 all contribute to sensation in the middle ear, external auditory canal, auricle, and peri-auricular tissues. Irritation of any portion of these cranial nerves can result in otalgia.otalgia can be the manifestation of myocardial ischemia (ie, an angina equivalent) because the vagus nerve provides sensory innervations for both structures. Intermittent<unk>  is much more likely to be associated, for example, with musculoskeletal conditions as temporomandibular joint (TMJ) dysfunction and other myofascial<unk>  dysfunction syndromes.otalgia classified as primary, which originated from the ear, and secondary, which originated outside the ear. When the ear examination is abnormal, the source of the<unk>  from the ear (primary otalgia); when the ear examination is typically normal, the<unk>  source is not the ear(secondary otalgia) .Examination should be carried out including inspection of nasal cavity, oral cavity, neck, and possibly the larynx.
