SALAZAR F., Cristofer; VICENCIO S., Daniela    FERNANDEZ R., Lara. Secondary or referred otalgia, what clinicians should know. Rev. Otorrinolaringol. Cir. Cabeza Cuello []. 2020, 80, 4, pp.531-539. ISSN 0718-4816.  http://dx.doi.org/10.4067/S0718-48162020000400531.

Otalgia is a common reason for consultation in otolaryngology and can be classified into two types: primary or secondary otalgia. Primary otalgia is a consequence of an otological disease while secondary otalgia arises from pathological processes that originate in other structures different than the ears, but share common neuronal pathways. These pathways involve cranial nerves V, VII, IX and X and cervical nerves C2 and C3. The most common causes of secondary otalgia are musculoskeletal pathology such as temporomandibular joint dysfunction and myofascial syndrome, dental pathology and oropharyngeal infections. To find the etiology of secondary otalgia, in most cases a medical history and physical examination will be sufficient, however there is a group of patients with risk factors that may require additional studies. The objective of this review is to give the reader tools to understand the different processes involved in secondary otalgia, know the most relevant related pathologies and thus give the clinician a guide to deal with this problem.
