OBJECTIVE: To determine the incidence of acoustic trauma in Mexican Army personnel from the artillery branch exposed to field training with heavy ordnance. MATERIALS AND METHODS: An observational, cross-sectional, and descriptive study was done with military personnel under 30 years old. Each underwent approximately 15 yearly training sessions with cannons or howitzers over a 3-year period. A clinical questionnaire, audiometry (ISO 389-1:1998, 389-3:1994, 389-4:1994), and tympanometry were performed to assess symptoms (subjective hearing loss, tinnitus) and detect acoustic trauma. RESULTS: There were included 25 participants, with a mean age of 25 years; 19 were male. Subjective hearing loss was reported by 6, and tinnitus by 2. Acoustic trauma was identified in 13 subjects, most commonly unilateral grade 1 (n = 8). In 12 no trauma was found. Tympanometry was normal (type A) in 19 cases. CONCLUSIONS: Acoustic trauma is highly prevalent among military personnel exposed to impulsive noise. The low rate of subjective symptom reporting highlights the need for regular audiological screening, preventive protocols, and optimized hearing protection. The predominant hearing damage is sensorineural. [ABSTRACT FROM AUTHOR] |

OBJETIVO: Determinar la incidencia de trauma acústico en personal del Ejército Mexicano perteneciente a la rama de artillería expuesto a prácticas con armamento pesado en campo abierto. MATERIALES Y MÉTODOS: Estudio observacional, transversal y descriptivo, en el que se incluyeron militares menores de 30 años que participaron en aproximadamente 15 prácticas anuales con cañones u obuseros durante un periodo de 3 años. Se aplicó un cuestionario clínico y se hicieron audiometrías con equipo calibrado según normas ISO (389-1:1998, 389-3:1994, 389-4:1994), así como timpanometrías. Se evaluaron síntomas auditivos (hipoacusia subjetiva, acúfeno) y trauma acústico. RESULTADOS: Se incluyeron 25 participantes. La edad media fue de 25 años; 19 eran hombres. De los 25 participantes 6 reportaron hipoacusia subjetiva y 2 acúfeno; 13 tenían algún grado de trauma acústico; el grado 1 unilateral fue el más frecuente (n = 8); 12 no tenían alteraciones. La timpanometría fue normal (tipo A) en 19 participantes. CONCLUSIONES: El trauma acústico es altamente prevalente en personal expuesto a ruido impulsivo militar. La baja percepción subjetiva subraya la necesidad de implementar tamizajes audiológicos periódicos, protocolos preventivos y ajustes en la protección auditiva. El daño auditivo predominante es neurosensorial. [ABSTRACT FROM AUTHOR] |
