Greater auricular nerve conduction in leprosy.

M Gourie-Devi

    Indian Journal of Leprosy
    |April 1, 1984

    Summary
    This summary is machine-generated.

    Nerve conduction studies can detect early signs of leprosy, even in nerves that appear normal. This electrophysiological method aids in the diagnosis of leprosy by identifying abnormal nerve conduction.

    Area of Science:

    • Neurology
    • Clinical Electrophysiology
    • Infectious Diseases

    Background:

    • Leprosy is a chronic infectious disease primarily affecting peripheral nerves.
    • Early diagnosis and treatment are crucial to prevent nerve damage and disability.
    • Assessing peripheral nerve function is important for understanding disease progression.

    Purpose of the Study:

    • To establish normal values for greater auricular sensory nerve conduction.
    • To evaluate the utility of sensory nerve conduction studies in diagnosing leprosy.
    • To identify electrophysiological abnormalities in leprosy patients.

    Main Methods:

    • Sensory nerve conduction studies were performed on the greater auricular nerve.
    • 18 healthy control subjects (36 nerves) and 12 leprosy patients (24 nerves) were included.

  • Electrophysiological parameters were analyzed and compared between groups.

    • Main Results:

    • Normal values for greater auricular sensory nerve conduction parameters were determined.
    • Abnormal nerve conduction was observed in 16 out of 24 nerves in leprosy patients.
    • Electrophysiological abnormalities were found in all thickened nerves and 8 clinically normal nerves.

    Conclusions:

    • Sensory nerve conduction studies are a valuable diagnostic tool for leprosy.
    • This electrophysiological method can detect nerve abnormalities even in clinically normal nerves.
    • The procedure aids in the early diagnosis and management of leprosy.
