Objective:

this study analyzed the spirometric values in children and adolescents with hearing losscompared with the spirometric variables of a control group, and quantify the respiratory changes made on13 volunteers? deficient group.

Methods:

It employed the Student t test for independent samples and wasconsidered the level ? of 5%. The volunteers were diagnosed with hearing loss from moderate toprofound. Participants with disabilities were evaluated by means of a form containing data regarding theclinical history to verify that they met the inclusion criteria of the study. The spirometry was performedwith the use of a nose clip, demonstrations and encouraging voice in running the test. The valuesmeasured were vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in one second(FEV1), Tiffenau index (FEV1/FVC), FEFmáx (FEF max), mean forced expiratory flow ( FEF 25% -75%) and maximum voluntary ventilation (MVV).

Results:

statistically significant reduction of FEFmáx(p ? 0.05) of the hearing impaired group compared with the control group. For most spirometricparameters evaluated did not differ between groups.

Conclusion:

There is a relationship between hearingloss and spirometric parameters in children and adolescents, as 30.8% of the results obtained from theseparticipants were biased standards obstructive, restrictive and moderate obstructive moderate.
