The use of language is a social act used to understand and transmit meaning. There are certain pathologies that disrupt this function, such as microtia. This pathology has been associated with hearing loss in 90%. The prevalence of language disorders reported by the American Academy of Pediatrics is 3%. In Mexico, the Instituto Nacional de Estadística y Geografía reported a 9% prevalence of language disorders. Methdos: This is a descriptive study of patients that have been diagnosed with microtia at “Dr. Manuel Gea González” General Hospital in Mexico City, Mexico. Results: A total of 125 patients, 40% are female and 60% are male, 16.8% with bilateral microtia and 83.2% are onesided, 61.5% are right auricular deformities and 38.5% are left. A mean age of 11.9 years. We found as a non syndromic deformity in 47.2%, and associated to other diseases in 52.8%. The audiologic deficit average is 72.6 dBHL. 67.2% did not have any type of speech or language disorder, 16.8% have a phonetic problem and 16% have a phonologic problem. Conclusions: The frequency of speech disorders in our active population is 32.8% (16.8 phonetic and 16% phonologic). The hearing threshold is 72.6dB.
