Leudet Tinnitus (also known as Leudet's Sign or Tinnitus Leudet) refers to an auditory phenomenon characterized by a continuous or intermittent perception of sound within the ear or head, unrelated to any external source of sound. Originating from the name of French physician Gabriel Leudet, the term signifies the presence of pulsatile tinnitus that can be observed through palpation of certain anatomical structures.
Leudet Tinnitus typically involves a rhythmic or pulsating sound that coincides with the individual's heartbeat, often referred to as pulsatile tinnitus. It is frequently perceived as a whooshing, thumping, or swooshing noise, similar to the sound of blood flow. The distinct characteristic of this type of tinnitus is that the sound synchronizes with the individual's pulse rate, appearing stronger during systole (when the heart contracts) and weaker during diastole (when the heart expands).
This condition can occur due to various underlying causes. It may be attributed to vascular abnormalities, such as increased blood flow, abnormal blood vessels, or the presence of arteriovenous malformations near the ear. Other causes may include turbulent blood flow, atherosclerosis, hypertension, or anatomical abnormalities within the ear or surrounding structures.
Leudet Tinnitus often necessitates medical evaluation to identify the specific cause and develop an appropriate treatment plan. Diagnostic procedures may involve physical examination, imaging studies (such as Doppler ultrasound, magnetic resonance angiography, or computed tomography angiography), and assessment of cardiovascular health. Treatment approaches vary depending on the underlying cause, and may range from medication or surgical intervention to managing contributing factors, such as stress reduction or lifestyle modifications.
