Abstract
Bilateral vocal fold paralysis (BVFP) is a relatively uncommon cause of respiratory distress. Many surgical techniques have been described to treat BVFP ranging from options as simple as a ventriculocordectomy as a glottis widening procedure, to as complex as reanimation of the larynx with an electrical device. Aim: The aim of the work is to compare the effect of both surgical techniques (laser posterior cordotomy and combined laser posterior cordotomy with suture lateralization) on respiration and quality of voice. Patients & methods: Forty patients were recruited from the ENT outpatient clinic in the Kasr El Aini hospital.The cases under study were divided into two groups; group (A) who underwent laser cordotomy and group (B)who underwent combined suture lateralization with laser cordotomy. They were subjected to pre & postoperative assessment of respiration using flexible laryngoscopy. Subjective & objective assessment of voice quality using VHI score and CSL parameters respectively. Results: No significant difference between both surgeries regarding respiratory efficiency, VHI scores and presence of postoperative aspiration. Significant difference was found regarding some CSL measures and granuloma formation. Conclusion: Combined laser posterior cordotomy with suture lateralization in bilateral vocal folds abductor paralysis showed less complications and better maximum phonation time and acomparable effect to laser cordotomyregarding respiration
