Seventeen cases of unilateral false cord hypertrophy in males between 42 and 81 years old (average 60.3years) were analysed by means of CT examination of the larynx. The hypertrophic site was on the left side in 16 cases and right side in 1 case by laryngoscopy. Eleven patients complained of hoarseness, and six had discomfort of the larynx.
The axial CT scan of the patients revealed concavity of the thyroid lam ina and various asymmetry of the thyroid cartilage, such as rotation, deviation and different length of the lamina. In these findings, predominant site of the thyroid lamina in the horizontal direction was in agreement with the hypertrophic site except in one case.
In conclusion, unilateral false cord hypertrophy may be associated with the same site of growing the thyroid lamina.
