Abstract
Background
Advances in surgical techniques have significantly improved the safety of thyroidectomy. Quality of life issues, such as voice changes, however continue to be important considerations. This study evaluated the prevalence and determinants of voice changes following thyroidectomies for non-malignant goiters in a Nigerian Hospital.
Methodology
Consecutive adults who had thyroidectomy for non-malignant goiters were evaluated. Preoperatively, each participant had laryngoscopy and voice assessment using the Voice Handicap Index-10. At surgery, the intubation difficulty score, size of endotracheal tubes, and duration of operation were recorded. Laryngoscopy and VHI-10 assessments were repeated 1 week, 1 month, and 3 months after surgery. Pre and postoperative assessments were compared.
Result
Fifty-four patients completed the study. Subtotal thyroidectomy was the commonest operation performed in 17 patients (31.48%), with 14 (25.93%) having total thyroidectomy. Baseline median VHI-10 score was 6.5(IQR-10). Five patients had abnormal preoperative laryngoscopy findings (benign vocal cord lesions). Postoperatively, seven patients had endoscopic evidence of vocal cord paralysis, six were unilateral while one was bilateral. Ten patients (18.5%) had early voice changes. Median VHI-10 score at one week was significantly higher than baseline (10 vs. 6.5, p = 0.01). At 3 months, VHI-10 reverted back to baseline in five of the ten patients while five patients (9.3%) had persistent voice changes. Abnormal endoscopic findings predicted the occurrence of early postoperative voice changes.
Conclusion
Thyroidectomy for non-malignant goiters is associated with transient voice changes, many of which revert to normal over time. Abnormal endoscopic findings predict its occurrence.
