Introduction: The treatment of glottis closure insufficiencies by vocal cord lipoaugmentation is a debated question. The authors report their 10 years experience with this method.

Materials and Methods: Between 1995 and 2005 24 patients (in 23 cases unilateral vocal cord paralysis and 1 bilateral vocal cord atrophy) were operated on with a minimum of 6 months after the development of the paralysis if the voice therapy was unsuccessful. The surgeries were performed in JET ventilation and by Weerda-laryngoscope approach. In our cases approximately 30%-50% overfilling of the autologous fat was used.

Results: In 22 patients significant improvement of voice quality was measured by the subjective tests, and only 2 patients required reoperation. The preoperative objective phoniatrical parameters of the last 6 cases, compared to the postoperative results detected in the end of the 1st post-operative year are the following: Maximum phonation time 2,5/10,4 sec; Fo: 210Hz/203Hz; Jitter% 3,6/0,3; Shimmer dB 1,18/0,26; Harmonicity(harmonic to noise ratio) 15,5/23,4.

Discussion: The presented cases prove that this cheep, minimally invasive technique can provide significant improvement of the voice quality in the long run without the risk of foreign body rejection or allergic reaction. Hence this method is a suitable way of primary treatment for the glottic closure insufficiencies.
