Summary
Hoarseness after thyroidectomy often results from recurrent laryngeal nerve injury. Most cases of vocal cord paralysis improve over time due to compensatory mechanisms of the unaffected vocal cord.
Area of Science:
- Otolaryngology
- Surgical Pathology
Context:
- Thyroidectomy is a common surgical procedure.
- Hoarseness is a potential post-operative complication.
- Recurrent laryngeal nerve injury can lead to vocal cord paralysis.
Purpose:
- To investigate the incidence and causes of hoarseness following thyroidectomy.
- To analyze the rate of recurrent laryngeal nerve (RLN) injury.
- To assess the recovery patterns of vocal cord paralysis.
Summary:
- This study reports 86 cases of hoarseness post-thyroidectomy, with 37 confirmed glottic paralysis cases.
- Recurrent laryngeal nerve injury accounted for 89.91% of paralysis cases (33/37), with 20 left and 16 right-sided injuries.
- Superior laryngeal nerve injury was rare. Most (13/16) cases of glottic paralysis showed improvement, attributed to contralateral vocal cord compensation.
Impact:
- Highlights the significant risk of recurrent laryngeal nerve injury during thyroidectomy.
- Provides data on the high incidence of vocal cord paralysis post-surgery.
- Suggests that vocal cord overcompensation is a key factor in hoarseness recovery.
