Difficulty in high-pitched phonation by laryngeal trauma. 1985

M Hirano, and S Kurita, and R Terasawa

We treated a case of laryngeal trauma in which difficulty in high-pitched phonation was the main feature of a voice problem. We emphasize the importance of phonatory function tests in determining the mechanism of voice disorders and in monitoring the effects of treatment. Physical examination, phonatory function tests, computed tomographic scan, and electromyogram disclosed that the voice problem was caused by a fracture of the thyroid cartilage and its fixation against the cricoid cartilage. An open reduction yielded recovery of the phonatory function.

D013957	Thyroid Cartilage	The largest cartilage of the larynx consisting of two laminae fusing anteriorly at an acute angle in the midline of the neck. The point of fusion forms a subcutaneous projection known as the Adam's apple.	Cartilage, Thyroid,Cartilages, Thyroid,Thyroid Cartilages
D014831	Voice	The sounds produced by humans by the passage of air through the LARYNX and over the VOCAL CORDS, and then modified by the resonance organs, the NASOPHARYNX, and the MOUTH.	Voices
D014832	Voice Disorders	Pathological processes that affect voice production, usually involving VOCAL CORDS and the LARYNGEAL MUCOSA. Voice disorders can be caused by organic (anatomical), or functional (emotional or psychological) factors leading to DYSPHONIA; APHONIA; and defects in VOICE QUALITY, loudness, and pitch.
