TRONCOSO P, Rodrigo; FUENTES L, Eduardo; ARACENA C, Karina  y  RIVERA B, Carla. Clinical masking: A literature review. Rev. Otorrinolaringol. Cir. Cabeza Cuello [online]. 2016, vol.76, n.3, pp.353-363. ISSN 0718-4816.  http://dx.doi.org/10.4067/S0718-48162016000300016.

Adequate use of masking is key in the correct diagnosis of hearing loss. Various methods are suggested regarding the application of clinical masking, hence the need to review literature in order to reach a consensus. To critically review the specialized literature and international societies' recommendations regarding clinical masking. From August to November 2015, PUBMED, SciELO and Google Scholar articles on clinical masking methods used in tonal audiometries were consulted, as well as international organization guidelines, and literature in the area of Audiology. Hood's plateau method, later revised, received the most references. The modified versions consider the number of increments needed to determine the true threshold, and the occlusion effect. Optimized methods show the variations regarding interaural attenuation, need for masking, initial masking level, increments to reach "The Plateau", and the occlusion effect. Literature shows differences regarding when and how to use masking; however, common criteria can be established with reference to the levels of interaural attenuation, when to use masking, occlusion effect values and methodology. The plateau method proposed by Hood is still the most recommended. Yacullo's optimization is currently the one with the most references and recommendations in specialized literature.

Palabras clave : Clinical masking; tonal audiometry; literature review; plateau method.
