Objectives:
Cigarette-associated diseases have frequently been detected in the field of otolaryngology. Cigarettes can cause changes in voice performance. The aim of the present study was to investigate the effect of e-cigarettes on voice performance compared with conventional cigarettes.
Materials And Methods:
This is a cross-sectional study that included 81 healthy volunteers. To provide standardization, all patients were men. The patients were divided into three groups: e-cigarette users (group 1, n = 21), conventional cigarette users (group 2, n = 30), and nonsmokers who had never smoked (group 3, n = 30). The subjective and objective voice analyses were performed for all the three groups in the study. F0, jitter %, shimmer %, shimmer dB, harmonics-to-noise ratio (HNR) values, and Voice Handicap Index 10 were statistically compared between all groups.
Results:
The mean Voice Handicap Index 10 values of the conventional cigarette users were higher than those of the e-cigarette users and control group. No significant difference regarding the F0, jitter, and shimmer percentage values between the groups was detected; however, a significant difference was detected regarding the shimmer dB and HNR values between the groups. The mean shimmer dB values of the conventional cigarette group were higher than those of the control group and electronic cigarette users, but the mean HNR values were lower than those of the control group and electronic cigarette users.
Conclusions:
The effects of e-cigarettes on voice were detected as mild compared with conventional cigarettes, according to the subjective and objective voice analysis results in our study.

Electrons are negatively charged subatomic particles that are attracted to an orbit around the positively-charged nucleus of an atom. They reside in locations that are associated with energy levels called shells and are further organized into sub-shells and orbitals within each shell.
Electrons Orbit the Nucleus
Electrons are found in specific locations outside of the nucleus. The shell in which an electron resides indicates the general energy level of the electron: those closer to the...
