Summary

Maxillary sinus hypoplasia (MSH) is a rare condition that can be misdiagnosed. Understanding its three types and associated uncinate process variations is crucial for accurate diagnosis and avoiding complications.

Area of Science:

  • Otolaryngology
  • Radiology
  • Anatomy

Background:

  • Maxillary sinus hypoplasia (MSH) is an uncommon condition often overlooked by otolaryngologists.
  • Computerized tomography (CT) scans are essential for detailing paranasal sinus anatomy.
  • MSH can be misdiagnosed as maxillary sinus infections or neoplasms.

Purpose of the Study:

  • To define the distinct patterns of maxillary sinus hypoplasia (MSH).
  • To investigate the relationship between MSH and variations in the uncinate process.
  • To present a series of MSH cases and their classifications.

Main Methods:

  • Retrospective analysis of 18 patients diagnosed with MSH via CT scans.
  • Classification of MSH cases into three distinct types based on sinus and uncinate process morphology.

  • Evaluation of associated paranasal sinus variations.

    • Main Results:

    • 18 patients with MSH were analyzed: 12 unilateral and 6 bilateral.
    • Classified cases: 13 Type I, 7 Type II, and 4 Type III MSH.
    • Identified three ethmomaxillary sinuses and an orbital extension of a posterior ethmoid cell.

    Conclusions:

    • MSH exhibits three distinct patterns, often associated with uncinate process anomalies.
    • Anomalies of the uncinate process in MSH can lead to orbital complications.
    • Awareness of these variations is critical for accurate diagnosis and management in otolaryngology.
