Summary

Intratemporal hemangiomas can cause facial palsy by compressing or invading the facial nerve. Surgical removal and nerve grafting offer good results for facial nerve function recovery.

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Oncology

Background:

  • Intratemporal hemangiomas are rare benign tumors.
  • These tumors frequently involve the facial nerve (CN VII).

Observation:

  • Eight patients with intratemporal hemangiomas affecting the facial nerve were analyzed.
  • Tumors typically affected the geniculate ganglion, internal auditory canal, or middle ear.
  • Facial palsy was the primary symptom, presenting with varied onset and progression.

Findings:

  • Hemangiomas caused facial nerve compression or invasion.
  • Bony remodeling with a honeycombed appearance was observed in two cases.
  • Complete tumor removal and facial nerve reconstruction were achieved in all patients.
  • Facial nerve grafting was necessary in five cases due to tumor-induced damage.

Implications:

  • Early diagnosis and surgical intervention are crucial for preserving facial nerve function.
  • Intratemporal hemangiomas require specialized surgical management.
  • Successful facial nerve repair depends on the duration of preoperative dysfunction.
