Does the Duration of Ofloxacin Otic Drops Matter in Immediate Post‐tube Otorrhea?

Abstract

Objective: The effect of upper respiratory tract diseases on phonation has been reviewed, but the effect of lower respiratory tract diseases on phonation has been little studied. The influence of asthma as a reversible obstructive small airway disease on phonatory variables is not clear yet. Method: This cross sectional, case control trial was performed from March to September 2008 to evaluate the quality of phonation in asthma. Eight vocal parameters were evaluated in 34 asthmatic patients and a control group by a voice meter device using Dr Speech statistical software. Results: Vocal variables such as FO, Jitter, and Shimmer were almost similar in both groups statistically. This fact likely reflects the normal phonatory mechanism at the level of vocal cords in asthmatic patients, but harshness, hoarseness, NNE, S/Z ratio ( P < .01) and breathy voice ( P = .015) were different statistically. This indicates the role of the lower airway in the phonation process. Conclusion: Small airway diseases such as asthma may have direct effect on phonation, but we suggest further studies with more cases.
