Summary
This summary is machine-generated.Thyroid cancer surgery by experienced surgeons generally does not affect voice quality, as measured by the Acoustic Voice Quality Index (AVQI). Most patients experience temporary vocal fold issues that resolve within three months post-thyroidectomy.
Area Of Science
- Otolaryngology
- Endocrinology
- Oncology
Background
- Voice alteration is a common concern following thyroid surgery, affecting patient quality of life.
- The Acoustic Voice Quality Index (AVQI) is utilized to objectively assess voice quality.
- Differentiated thyroid carcinoma (DTC) necessitates surgical intervention, raising questions about vocal outcomes.
Purpose Of The Study
- To prospectively evaluate vocal outcomes after thyroidectomy using the AVQI.
- To determine the impact of differentiated thyroid carcinoma (DTC) surgery on voice quality.
- To correlate pre- and postoperative AVQI scores with surgical factors.
Main Methods
- Prospective observational study of 74 DTC patients undergoing thyroid surgery.
- Vocal analysis using Acoustic Voice Quality Index (AVQI) and Praat software.
- Preoperative and postoperative endoscopic evaluation of vocal folds and AVQI scoring at multiple time points (T1, T2, T3).
Main Results
- Vocal fold impairment occurred in 6.76% of patients post-surgery, with full recovery within 3 months.
- A significant proportion of patients (37) presented with preoperative hoarseness (AVQI > 2.35), with many maintaining this post-surgery.
- No significant differences in mean AVQI scores were found based on gender, age, or central neck dissection.
Conclusions
- Thyroid surgery for DTC, when performed by experienced surgeons, does not significantly impact long-term voice quality.
- AVQI scores showed no significant variations between pre- and postoperative assessments.
- Temporary vocal fold issues are common but typically resolve, indicating good functional outcomes post-thyroidectomy.

The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
