Injury of hypoglossal nerve

Last edited: 4/16/2026

Overview

Hypoglossal nerve injury results in unilateral or bilateral tongue paralysis, affecting speech, swallowing, and tongue mobility. Bilateral injuries can lead to significant functional impairment requiring comprehensive rehabilitation 1.

Diagnosis

  • Clinical Presentation: Tongue deviation towards the affected side, atrophy, and impaired tongue mobility 1.
  • Neurological Examination: Essential for identifying paralysis and assessing severity 1.
  • Imaging: Not typically required unless trauma extent necessitates 1.
  • Electromyography (EMG): May help in assessing nerve function and recovery 1.

    • Management

  • Surgical Exploration and Repair: Recommended for suspected nerve severance to facilitate nerve suture 1.
  • Interfascicular Suture: Under microscopic guidance to improve recovery of tongue tone and motility 1.
  • Speech and Logopedic Rehabilitation: Crucial for functional recovery, especially in cases of total paralysis 1.
  • Supportive Therapies: Including physical therapy focused on tongue exercises to enhance recovery 1.

    • Special Populations

  • No Specific Guidance Provided: Abstracts do not cover unique considerations for pregnancy, pediatrics, elderly, or comorbidities 1.

    • Key Recommendations

  • Perform surgical exploration and interfascicular suture under microscopic guidance in cases of suspected hypoglossal nerve severance to enhance recovery outcomes (Evidence: Strong 1).
  • Initiate comprehensive speech and logopedic rehabilitation early in the management plan to improve functional outcomes (Evidence: Moderate 1).
  • Consider electromyography to assess nerve function and monitor recovery progress (Evidence: Weak 1).
