“…Paradoxical movement of the paralyzed vocal fold was observed in 4 subjects based on CT endoscopic and coronal MPR image analysis. Three other subjects (15,19, and 33) had probable paradoxical movement. Coronal MPR images of subjects 15 and 19 showed that the vocal fold on the affected side was thicker during inspiration than during phonation, although CT endoscopic images viewed from the oral and tracheal sides did not indicate apparent abduction of the affected vocal fold during phonation.…”

“…This disorder of unknown etiology may be asymptomatic or can cause hoarseness, fatigue on phonation, and laryngeal discomfort [10]. Computed tomography scan can help in confirming diagnosis of CTJ dislocation, while at the same time ruling out inflammatory or neoplastic processes.…”

The objective of this study is to assess and propose a method of diagnosis and management of patients with unilateral thyroarytenoid muscle palsy (TAMP). This is a retrospective review of clinical records. The records of seven patients diagnosed as having idiopathic TAMP were reviewed. Despite the adductive and abductive functions of the vocal folds being within normal range, apparent palsy was seen in the unilateral thyroarytenoid muscle of these patients. TAMP was confirmed by laryngeal electromyography, and the adductive and abductive movements of the vocal folds were evaluated as the mobility of the arytenoid cartilages by three-dimensional computed tomography and endoscopy. Most of patients with TAMP had been diagnosed as having other diseases or normal, and in one patient, it took over 6 years to establish a correct diagnosis. Two patients recovered by conservative treatment; however, in five patients, TAMP remained even after 6 months. In 4 of those 5 patients, treatment with hyaluronic acid injections was performed. In the remaining patient, surgical treatment, namely, nerve-muscle pedicle flap implantation was performed, which resulted in a favorable recovery of phonation. The average maximum phonation time (MPT) of all patients was extended from 11.4 (±4.4) s before treatment to 19.9 (±4.3) s after treatment, and the pitch range was also increased from 25.1 (±7.2) to 34.6 (±5.8) semitones following our management course. Our results indicate that there is a possibility that TAMP can be diagnosed and treated sufficiently. Therefore, further research toward establishing the concept of and treatment for TAMP is anticipated.
