Area of Science:

  • Otolaryngology
  • Head and Neck Surgery
  • Diagnostic Imaging

Background:

  • Parapharyngeal space tumors are rare, comprising 0.5% of head and neck neoplasms.
  • These tumors present diagnostic challenges due to varied histology and surgical excision difficulties.

Purpose of the Study:

  • To present a series of parapharyngeal space tumor cases.
  • To discuss diagnostic investigations and surgical approaches for these rare tumors.

Main Methods:

  • Retrospective review of 13 patients treated between 1981 and 1988.
  • Clinical presentation analysis, including physical examination findings.
  • Diagnostic imaging, primarily high-resolution computed tomography (CT) with contrast; angiography when vascularity suspected.

Main Results:

  • Most patients presented with a painless upper neck lump and lateral pharyngeal wall bulge.
  • Common pathologies included salivary gland tumors, neurolemmomas, and paragangliomas.
  • Surgical approaches focused on maximal exposure and vascular control.

Conclusions:

  • Accurate diagnosis through appropriate investigations like CT scans is vital.
  • Avoiding unnecessary procedures such as 'lymph node' biopsy or 'tonsillectomy' reduces patient morbidity.
  • Effective management relies on recognizing the specific nature of parapharyngeal space tumors.
