Summary
Thyroid surgery can injure the superior laryngeal nerve (SLN), impacting professional voice users. This study found a 5% incidence of SLN injury after thyroidectomy, highlighting the need for careful diagnosis.
Area of Science:
- Otolaryngology
- Head and Neck Surgery
- Neurosurgery
Background:
- Recurrent laryngeal nerve injury is a known thyroid surgery complication.
- Superior laryngeal nerve (SLN) injury is less recognized due to diagnostic challenges.
- This study aimed to determine the incidence of SLN injury post-thyroidectomy.
Purpose of the Study:
- To document the incidence of superior laryngeal nerve injury following thyroidectomy.
- To assess the diagnostic utility of laryngeal videostroboscopy and electromyography for SLN injury.
Main Methods:
- Twenty patients undergoing thyroidectomy were evaluated 3 months post-surgery.
- Evaluation included laryngeal videostroboscopy, laryngeal electromyography, and patient interviews.
- A 9-month study period was utilized for patient recruitment.
Main Results:
- One patient (5%) was diagnosed with unilateral superior laryngeal nerve injury.
- The study identified a significant risk of SLN injury during thyroidectomy.
Conclusions:
- Superior laryngeal nerve injury is a significant risk during thyroidectomy.
- SLN injury can have devastating consequences for professional voice users.
- Laryngeal videostroboscopy and electromyography are crucial for diagnosing SLN injury.

Cranial Nerves: Types Part II
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.

The Thyroid Gland
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...

Larynx
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, corniculates, and...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...
Goiter
Goiter refers to an abnormal enlargement of the thyroid gland that may appear as a diffuse goiter (uniform enlargement) or nodular (single or multiple nodules). Functionally, it is classified as nontoxic (normal/low hormone levels) or toxic (excess hormone production).PathophysiologyDiffuse thyroid enlargement typically results from prolonged stimulation by thyroid-stimulating hormone (TSH) or TSH-like agents, commonly seen in hypothyroidism or iodine deficiency. In contrast, in hyperthyroid...
Hypothyroidism II: Pathophysiology
Hypothyroidism is a disorder characterized by insufficient production of thyroid hormones, which regulate metabolism, energy balance, and multiple organ systems.TypesHypothyroidism is classified based on the level of dysfunction. Primary hypothyroidism results from intrinsic thyroid gland dysfunction, causing reduced hormone production despite normal or increased stimulation. Secondary hypothyroidism arises from inadequate thyroid-stimulating hormone (TSH) secretion by the pituitary. Tertiary...
