Facial nerve dysfunction after parotidectomy is linked to surgery extent and tumor location. Temporary weakness is common, especially with neck dissection, but permanent issues are rare and often affect the marginal mandibular branch.

Area of Science:

  • Otolaryngology
  • Head and Neck Surgery
  • Neurosurgery

Background:

  • Parotidectomy is a common surgical procedure for parotid gland pathologies.
  • Facial nerve dysfunction is a significant concern following parotidectomy.
  • Understanding risk factors is crucial for patient counseling and surgical planning.

Purpose of the Study:

  • To determine the incidence of facial nerve dysfunction after parotidectomy.
  • To correlate facial nerve dysfunction with surgical extent, pathology, and clinical setting.
  • To identify predictors of temporary and permanent facial nerve injury.

Main Methods:

  • A review of prospectively collected data from a head and neck database.
  • Analysis of 259 parotidectomies performed between 1987 and 1995.

  • Correlation of facial nerve function with tumor characteristics, surgical approach, and patient history.

    • Main Results:

    • 29% incidence of temporary facial weakness in patients with preserved nerves.
    • Higher rates of weakness associated with sialadenitis, deep-seated tumors, and prior surgery.
    • Permanent weakness occurred in 5.6% of patients, primarily affecting the marginal mandibular branch with neck dissection.

    Conclusions:

    • Temporary facial weakness after parotidectomy is influenced by surgical extent, tumor location, prior surgery, and concurrent neck dissection.
    • Permanent facial nerve deficits are infrequent and often localized to the marginal mandibular nerve when neck dissection is performed.
