Objectives:
This randomized case-control study compares teachers with self-reported voice problems to age-, gender-, and school-matched colleagues with self-reported voice health. The self-assessed voice function is related to factors known to influence the voice: laryngeal findings, voice quality, personality, psychosocial and coping aspects, searching for causative factors of voice problems in teachers.
Methods:
Subjects and controls, recruited from a teacher group in an earlier questionnaire study, underwent examinations of the larynx by high-speed imaging and kymograms; voice recordings; voice range profile; audiometry; self-assessment of voice handicap and voice function; teaching and environmental aspects; personality; coping; burnout, and work-related issues. The laryngeal and voice recordings were assessed by experienced phoniatricians and speech pathologists.
Results:
The subjects with self-assessed voice problems differed from their peers with self-assessed voice health by significantly longer recovery time from voice problems and scored higher on all subscales of the Voice Handicap Index-Throat.
Conclusions:
The results show that the cause of voice dysfunction in this group of teachers with self-reported voice problems is not found in the vocal apparatus or within the individual. The individual's perception of a voice problem seems to be based on a combination of the number of symptoms and of how often the symptoms occur, along with the recovery time. The results also underline the importance of using self-assessed reports of voice dysfunction.

Larynx
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
