OBJECTIVES: Use decision making tools to determine which of three alternatives - Cochlear Implants, Hearing aids or no treatment- assure that a person, who suffers from Deep Neursosensorial Hypoacusia, will achieve the best cost-productivity relation for his or her life.  METHODS: This study is based on a decision making analysis methodology which includes a description of the problem, a bibliographic review, a formulation of the problem, data analysis and incorporation, a mathematical model and results analysis. The problem is described as an alternatives issue concerning different treatments for Deep Neurosensorial Hypoacusia and a cost-productivity relation in order to evaluate each of the alternatives. This relation is measured as the NPV of the salary cash flow that the patient expects to receive during his/her productive life as compared with the treatment and education costs. Actual data from the Cochlear Group of the Fundacion Santafe concerning audiology and language comprehension levels from patients using different treatments for deep deafness is analyzed in order to generate probability distributions and develop an influence diagram. Finally, a sensitivity analysis is conducted in order to verify the robustness of the solution obtained. RESULTS: As a result of the study was obtained that the cochlear implant provides a cost-productivity relation of COP$253,936,210 (US$123,871), Hearing aids: COP$ 138,307,940 (US$67,467)  and not following any treatment: COP$107,510,318 (US$52,444). According to this assessment, the cochlear implant is the best treatment. CONCLUSIONS: According to the results, individuals who use a cochlear implant have a productivity of 1.5 times higher for individuals with hearing aids and almost 3 times higher than individuals who do not follow any treatment. This confirms the excellent performance in terms of effectiveness and utility of the cochlear implant compared to hearing aids. The sensitivity analysis conducted showed that the cochlear implant is the best decision in a real scenario.
