ABSTRACT
Background: Based on international epidemiology, some laryngeal
diseases could be more frequent at certain ages. The objective was to
describe endoscopic findings in patients through distinct decades of age
in a laryngoscopy facility.
Methods: retrospective and descriptive study; clinical and endoscopic
records were collected from 1493 procedures performed between 2009
and 2015, and organized in five groups of age for analysis. Differences
among them were analyzed by chi squared and ANOVA.
Results: 70% of patients reported dysphonia as a main symptom; 24%
of subjects were referred with cancer diagnosis and just 7% of them,
showed findings related to malignancy; on the other hand, cancer suspicion
increased in direct proportion with age (
p ‹ 0.0001); inespecific
inflammation and other benign endoscopic manifestations (e.g. vocal
fold paralysis, subglotic stenosis and nodules) represented 80% of the
whole findings; 14% of the procedures were reported as normal. Glottic
and supraglottic structures were the two regions affected by malignancy;
this finding was directly related to advanced age, particularly in patients
of 70 years of age or older. Finally, subglottic stenosis was observed in
patients younger than 50 years of age (
p ‹ 0.0001).
Conclusion: Causes of laryngeal diseases are different in individuals
according to their age. Carcinoma was more prevalent in adults of 70
years of age or older. Benign causes were secondary to inflammatory
and functional conditions
