Our Experience with Kashimas Procedure for Bilateral Abductor Vocal Cord Palsy

Introduction: Kashima operation, also known as endoscopic laser cordotomy is used for the treatment of bilateral abductor vocal cord palsy where the glottis chink is made posteriorly, sufficient enough for patient to breathe comfortably without any strider.   Materials and Methods: This Clinical Trial Was Performed On 12 Patients[1] with Bilateral Abductor Vocal Cord Paralysis. All Patients Underwent Kashimas Procedure and Post-Operative Voice, Respiratory and Deglutition Function Were Evaluated.   Results: 75% of patients were females and the mean age of patients was 40.9 ±9.13 years. In our patients, the most common etiology of bilateral vocal cord palsy was thyroid surgery (n=10, 83.33%).There was a significant improvement in breathing after surgery (P=0.001). After the procedure, 70% of patient had mild voice handicap score, and MPT was in normal range in 91.6% of cases.   Conclusion: Kashimas procedure is a satisfactory surgical treatment for treating bilateral vocal cord palsy in regards to strider. No aspiration was seen in any of the patients post-surgery and voice outcome of these patients was also satisfactory.
