Anatomical variations in the uncinate process are linked to chronic sinusitis. Uncinatectomy is the recommended surgical treatment for this condition, with CT scans being essential for safe procedures.

Area of Science:

  • Otolaryngology
  • Medical Imaging
  • Pathology

Background:

  • The uncinate process is a key anatomical structure within the osteomeatal complex.
  • Anomalies of the uncinate process can obstruct sinus drainage, potentially leading to sinusitis.

Purpose of the Study:

  • To investigate the ultrastructural and anatomical variations of the uncinate process.
  • To correlate these variations with the presence and etiology of chronic sinusitis.

Main Methods:

  • Examination of 15 uncinate processes using scanning electron microscopy.
  • Analysis of 32 high-resolution coronal CT scans in patients with septal deformity or sinusitis.

Main Results:

  • Pathological ultrastructural changes were observed in the uncinate process of patients with chronic sinusitis.

  • Anatomical variations including medial deviation, lateral deviation, pneumatization, and hypertrophy of the uncinate process were identified.

    • Conclusions:

    • Anatomic variations in the osteomeatal complex, particularly involving the uncinate process, are implicated in the development of chronic sinusitis.
    • Uncinatectomy is presented as the primary surgical intervention for chronic sinusitis.
    • Preoperative and intraoperative CT imaging is crucial for surgical planning and complication avoidance.
