Supraglottis

The supraglottis is the upper part of the larynx, also known as the voice box. It is located above the vocal cords and extends upwards to the base of the tongue. This anatomical region plays a crucial role in breathing, swallowing, and voice production. Key structures within the supraglottis include the epiglottis, aryepiglottic folds, false vocal cords (ventricular folds), and the arytenoid cartilages. The epiglottis is a flap of cartilage that acts as a protective lid, preventing food and liquid from entering the airway during swallowing. The false vocal cords, situated superior to the true vocal cords, are involved in voice modulation and airway protection. The aryepiglottic folds form the upper boundary of the larynx and contribute to sphincter function. The supraglottis is a common site for various medical conditions, including inflammation (supraglottitis), infections, and malignant tumors. Inflammation of the supraglottis, known as supraglottitis, can cause severe throat pain, difficulty swallowing, and breathing difficulties, and is a medical emergency. Malignancies in this region, such as squamous cell carcinoma, are often associated with risk factors like smoking and alcohol consumption and may present with symptoms like persistent sore throat, hoarseness, or a neck mass. Diagnosis and treatment of supraglottic conditions typically involve laryngoscopy, imaging studies, and appropriate medical or surgical interventions.
