“…In fact, the physiopathology of hearing loss involves a reduction in cochlear blood flow and gaseous exchange, and contemporaneous increased levels of circulating CO caused by chronic exposure to cigarette smoking further reduces the quantity of oxygen to the cochlear cells, thus contributing to sensory neural damage. This hypothesis, suggested by Matschke [19] in acute noise-induced damage, was subsequently confirmed by the studies of Fechter et al [20][21][22], Rao et al [23] and Shahbaz Hassan et al [24] for chronic noise-induced damage. Rao et al [23], in an experimental study, highlighted that the simultaneous exposure to noise and CO increases noise-induced hearing loss.…”

The few studies evaluating the changes caused by cigarette smoking on hearing loss induced by occupational exposure to noise have reached discordant conclusions. The aim of this study is to investigate the interactions between cigarette smoking and occupational exposure to noise as risk factors in the onset and development of hearing loss. The study was performed on a sample of 557 shipyard workers exposed to noise at an Equivalent Level (Leq) of 93 dBA. On the basis of their smoking habits, they were divided into three groups: group (A), non-smokers; group (B), smokers (15-30 cigarettes per day); and group (C), heavy smokers (over 30 cigarettes per day). The study focussed on the audiometric responses of the subjects at the frequencies of 500, 1000, 2000, 3000 and 4000 Hz. The results were then compared using statistical techniquees (Internal correlation coefficient, exponential model, ANCOVA, NPC test). Comparison of the audiometric responses showed statistically significant differences between the three groups. Non-parametric analysis, performed using the NPC test, highlighted that the interaction between smoking and exposure to noise has an influence on hearing loss at all frequencies, and particularly at high frequencies (3000-4000 Hz). The data obtained from the examined sample show that smoking and exposure to noise cause an increase in occupational hearing loss and that this is directly related to the number of cigarettes smoked

“…These numbers correspond to the amount of smokers in the population of Germany (27.2%) [41]. A signiWcant diVerence in age between smokers and non-smokers has been stated by other authors before [42,43]. Like this study these works also include trends-without signiWcance-for less improvement of hearing abilities in smokers.…”

Idiopathic sudden sensorineural hearing loss (ISSNHL) is a heterogenic disease. Multiple factors influencing aetiology and prognosis are discussed. A retrospective clinical characterisation and analysis of family history of ISSNHL patients was performed to investigate influences on the disease. 186 inpatients diagnosed with ISSNHL were characterised by health records and a standardised questionnaire. Audiograms were observed. 75 controls that had never experienced an event of ISSNHL were questioned about family members being affected by ISSNHL. 63.4% of all patients could be assigned to at least one group with similar causes of ISSNHL (noise exposure, positive family history, infectious diseases, hypothyroidism and fibromuscular dysplasia). A positive family history for ISSNHL has not been reported so far. Therefore, we accentuated the characterisation of patients with positive family history. 21.4% affirmed a positive family history. In ten families, at least two family members were reported as ISSNHL patients. In comparison with patients with negative family history, they tend to be younger, experience more events of ISSNHL and show less improvement of hearing abilities under therapeutic treatment (non-significant). Differences intensified between smokers with positive family history and non-smokers with negative family history. Differences concerning average age were statistically significant (p = 0.001). Within 75 controls 11 families were reported with one member being affected by ISSNHL. In the control group we did not detect any family with more than one ISSNHL patient. The results indicated that patients with positive family history tend to have an aggravated course of ISSNHL. Further studies should help to confirm these results and to identify environmental or genetic factors leading to ISSNHL. This might support a better understanding of the aetiology of ISSNHL and offer new possibilities for prevention and therapy.

“…Nicotine increases platelet aggregation (Saba & Mason, 1975), which plays an important role in the development of atherosclerosis. Although the vasoconstrictory effects of nicotine in the blood vessels are typical, vessels of the central nervous system and coronary arteries are known to dilate in response to nicotine (Matschke, 1991). It remains to be investigated whether the longer term effects of smoking are associated with the effect of noise exposure on permanent hearing loss.…”

The objectives of the present study were to evaluate both the respective and combined effects of occupational noise exposure and smoking on hearing, taking age into consideration. The evaluation was conducted using 1478 subjects without a history of ear disease out of a population-based sample of 2267 adults, aged 40 79 years. Pure-tone audiometry and a questionnaire were administered. A deleterious effect of noise exposure on hearing was significantly observed in both genders at many frequencies after adjustment for age, income, and education. The smoking habit alone significantly affected hearing deterioration at 4000 Hz in noise-unexposed males. The combined effect of noise and smoking was not interactive but additive. A dose-response effect of smoking on hearing loss was observed in middle-aged males without noise exposure. Smoking and noise exposure were associated with hearing loss respectively.. This result is noteworthy for the preservation of good hearing especially at the beginning of aging.
