Maxillary sinus hypoplasia (MSH) is a rare condition of decreased sinus volume. This case suggests that ostial obstruction alone may not solely cause MSH, challenging current theories.

Area of Science:

  • Otolaryngology
  • Radiology
  • Pathophysiology

Background:

  • Maxillary sinus hypoplasia (MSH) is characterized by reduced maxillary sinus volume.
  • The exact pathophysiology of MSH remains debated.
  • Ostial obstruction and negative sinus pressure are commonly implicated.

Observation:

  • A case of progressive unilateral MSH was observed.
  • The affected sinus exhibited an open ethmoid infundibulum.
  • An open accessory ostium was also present on the same side.

Findings:

  • The presence of both an open ethmoid infundibulum and an accessory ostium in unilateral MSH was noted.
  • These anatomical findings challenge the exclusive role of ostial obstruction.

Implications:

  • Ventilatory dysfunction due to ostial obstruction alone may not be the sole cause of MSH.
  • This challenges the established etiological factors in MSH pathogenesis.
  • Further research into the multifactorial causes of MSH is warranted.
