In total, 242 temporal bone images were reviewed. Patients' ages ranged between 6 and 86 years. Age was shown to have a significant linear relationship (<italic>P</italic> < 0.001) such that for every unit increase in age the predicted thickness was reduced by 0.0047 mm.</p> </sec> <sec id="lary25243-sec-0005" sec-type="section"> <title>Conclusions</title> <p>The thickness of the SSC decreases with advancing age.</p> </sec> <sec id="lary25243-sec-0006" sec-type="section"> <title>Level of Evidence</title> <p>4. <italic>Laryngoscope</italic>, 125:1940–1945, 2015</p> </sec> </abstract>
