Nasal dermal sinuses and cysts rarely extend into the brain. Clinical examination and CT scans effectively determine the extent of these congenital midline lesions.

Area of Science:

  • Neurosurgery
  • Pediatric Surgery
  • Dermatology

Background:

  • Nasal dermal sinuses and cysts are congenital midline malformations.
  • These lesions can sometimes present with intracranial extension.

Purpose of the Study:

  • To evaluate the incidence of intracranial extension in patients with nasal dermal sinuses and cysts.
  • To assess the diagnostic utility of clinical examination and CT scans in these cases.

Main Methods:

  • Retrospective review of 32 patients treated for nasal dermal sinuses and cysts between 1978 and 1987.
  • Analysis of clinical presentation, CT scan findings, and surgical outcomes.

Main Results:

  • Only 6 of 32 patients (19%) had intracranial extension.

  • All patients with intracranial extension showed an intracranial mass on CT.
  • 10 patients without CT evidence of intracranial mass had only a fibrous cord, with 4 confirmed to have no intracranial extension upon craniotomy.
  • 4 patients with sinus ostia at the columella had no intracranial extension.

    • Conclusions:

    • Intracranial extension of nasal dermal sinuses and cysts is uncommon.
    • Clinical examination and preoperative CT scans are valuable tools for assessing the extent of these lesions.
    • A fibrous cord to the foramen cecum does not always indicate intracranial extension.
