Objectives: Endoscopic arytenoid lateralization is one of the treatment options of bilateral vocal cord palsy. This method causes only a minimal damage in laryngeal structures, thus good phoniatric outcome can be expected after surgery.

Methods: 28 consecutive patients (follow-up period is more than 1 year) operated for bilateral palsy, were divided into three main groups. The movement of the vocal cord recovered in one or both sides in 12 patients thus the lateralization was suspended. In 7 patients only partial recovery was detected, hence the lateralization was sustained. In 9 patients the palsy was complete on both sides. The measured patameters were F0, MPT, harmonicity, Jitt and Shimm.

Results: In full recovery of one or both sides good voice quality was detected. In partial recovery (persisting lateralization) the voice in 4 out of 7 was good, 3 was hoarse but acceptable. In 4 out of 9 patients with no movement recovery acceptable voice was detected by using false vocal cord phonation and 5 had whispering, hoarse voice.

Conclusion: Results show that endoscopic arytenoid lateralisation can be used in temporary palsy without significant damage in phonation. In cases of permanent palsy in the most cases voice was socially acceptable due to the residual movements of the larynx.
