Evaluation of voice quality in primary hyperparathyroidism patients undergoing minimally invasive parathyroid surgery

Abstract

Objective: Voice quality disorders remain a problem with classical surgical method which is expected to decrease with new minimally invasive methods. We aimed to examine whether there is an impairment in voice quality among our patients who have undergone open minimally invasive parathyroid surgery. Methods: Forty-seven primer hyperparathyroidism patients included in the study. Their video laryngoscopic evaluations and voice analyses were done in pre-operative and post-operative 6th month, and changes in the voice quality were examined. Results: Eighty-five (85.1%) of patients were female, with a mean age of 51.5 +/- 9.4. According to the voice analysis in the preoperative-postoperative 6th months, F0 (%): 210.616-211.443, Jitt (%): 0.699-0.735, RAP (%): 0.420-0.444, Shim (%): 2.535-2.736, NHR (dB): 0.119-0.123, and VTI: 0.044-0.045, respectively. No significant differences were observed in any of the acoustic parameters between the pre-and post-operative periods. Conclusion: No deterioration in voice quality was observed in patients undergoing novel minimally invasive surgical technique. In this respect we think that this new method will be much more advantageous in terms of preserving the voice quality in eligible patients.
