Sessions
this is a panel presentation for Assessment, office-based and endolaryngeal approach for Unilateral Vocal Fold Immobilty
Description
This session reviews the critical molecular landscape of head and neck squamous cell carcinoma (HNSCC). We will examine key genetic alterations and signaling pathways, including TP53, NOTCH1, and EGFR/PI3K. The presentation highlights how these genetic drivers influence tumor progression, metastasis, and resistance to current treatment modalities, offering a snapshot of the current genomic understanding of the disease.
Outcome Objectives
Identify major genetic mutations and chromosomal alterations associated with head and neck cancer.
Understand the relationship between specific genetic pathways and clinical disease behavior.
Evaluate the potential of these genetic pathways as targets for future precision medicine and therapeutic interventions.
Background
Head and neck cancer exhibits significant molecular heterogeneity, which often complicates treatment and prognosis. While traditional risk factors are well-known, the underlying genetic mechanisms driving carcinogenesis are complex. Elucidating these genetic pathways is essential for developing novel biomarkers and targeted therapies, ultimately aiming to improve survival rates and reduce treatment-related morbidity.
Diseases of the thyroid and parathyroid glands—both endocrine organs—are frequently encountered in worldwide. Approximately 5–15% of all thyroid nodules are malignant in nature. Thyroid cancers account for about 90% of all endocrine neoplasms. Reported rates of metastasis to the central and lateral neck compartments in thyroid cancers range from 20% to 80%.
Diagnosis, treatment, and follow-up of diseases of these organs require a multidisciplinary approach involving Endocrinology, Nuclear Medicine, Pathology, and Surgery. In recent years, various surgical approaches such as lobectomy, total thyroidectomy, central lymph node dissection, and minimally invasive thyroidectomy have been applied, differing from past practices. With the advancement of technology, endoscopic and robotic surgery have also been introduced into thyroid surgery in recent years.
Although guidelines set forth by the American and European Thyroid Associations exist for surgical management of thyroid diseases, different surgical practices are preferred in various parts of the world. Due to the location of the thyroid in the neck and the potential complications of its surgery—such as recurrent or superior laryngeal nerve injury, tracheal or laryngeal trauma, and swallowing difficulties—this topic is of particular importance to the specialties of Otorhinolaryngology and Head & Neck Surgery.
The most effective way to avoid complications is a thorough knowledge of the surgical anatomy of these organs and mastery of surgical techniques.
In this course, current thyroid surgery techniques and methods to prevent possible complications will be presented, accompanied by visual educational materials.
