Postoperative swallowing disorder after thyroid and parathyroid resection

Area of Science:

• Endocrinology
• Surgical Oncology
• Otolaryngology

Background:

• Dysphagia is a common complication following thyroidectomy.
• Understanding the incidence and risk factors for postoperative dysphagia is crucial.

Purpose of the Study:

• To investigate the incidence of dysphagia after thyroidectomy and parathyroidectomy.
• To analyze diagnostic and therapeutic approaches for postoperative dysphagia.
• To identify patient risk factors for developing dysphagia.

Main Methods:

• A questionnaire was administered to 372 patients undergoing thyroid or parathyroid surgery.
• Patients were evaluated at least 6 months postoperatively.
• Data analysis included correlation with patient demographics, specimen volume, BMI, and surgical invasiveness.

Main Results:

• 21.3% of patients reported improved swallowing post-surgery.
• 50.2% experienced temporary dysphagia, resolving spontaneously.
• 17.6% had persistent dysphagia beyond 3 months.
• Graves' disease and carcinoma were associated with increased dysphagia risk.
• Hyperparathyroidism correlated with a decreased risk of dysphagia.

Conclusions:

• Approximately 20% of patients experience postoperative dysphagia after thyroid and parathyroid surgery.
• Surgical invasiveness, Graves' disease, and carcinoma are significant risk factors.
• Hyperparathyroidism is associated with a reduced risk of dysphagia.
