RESUMO
Las armas de aire comprimido son utilizadas desde hace muchos años con distintos usos que van desde el tiro recreativo hasta el control de plagas. Las más comunes son aquellas que disparan ''balines" o esferas metálicas que pueden llegar a tener capacidad de penetrar tejidos dependiendo del tipo de carga y de la longitud del cañón. Se presenta un caso clínico de un masculino que fue agredido con un arma tipo pistola con carga de CO2 que recibió un impacto a nivel facial y sufrió laceración en piel de labio y fractura dental complicada.
Air guns have been used for many years for a variety of purposes ranging from recreational shooting to pest control. The most common are those that shoot "pellets" or metallic spheres that can penetrate tissues depending on the type of load and the length of the barrel. A clinical case is presented of a male who was assaulted with a CO2-loaded pistol-type weapon, hit at facial level, and suffered laceration of the lip's skin and complicated dental fracture.

OBJECTIVE: To characterize the impulse noise exposure and auditory risk for air rifle users for both youth and adults. DESIGN: Acoustic characteristics were examined and the auditory risk estimates were evaluated using contemporary damage-risk criteria for unprotected adult listeners and the 120-dB peak limit and LAeq75 exposure limit suggested by the World Health Organization (1999) for children. STUDY SAMPLE: Impulses were generated by nine pellet air rifles and one BB air rifle. RESULTS: None of the air rifles generated peak levels that exceeded the 140 dB peak limit for adults, and eight (80%) exceeded the 120 dB peak SPL limit for youth. In general, for both adults and youth, there is minimal auditory risk when shooting fewer than 100 unprotected shots with pellet air rifles. Air rifles with suppressors were less hazardous than those without suppressors, and the pellet air rifles with higher velocities were generally more hazardous than those with lower velocities. CONCLUSION: To minimize auditory risk, youth should utilize air rifles with an integrated suppressor and lower velocity ratings. Air rifle shooters are advised to wear hearing protection whenever engaging in shooting activities in order to gain self-efficacy and model appropriate hearing health behaviors necessary for recreational firearm use.
