Chronic maxillary atelectasis (CMA), a rare sinus condition, is often caused by blocked maxillary ostia. Surgical restoration of sinus ventilation via middle meatal antrostomy is the recommended treatment.

Area of Science:

  • Otolaryngology
  • Radiology
  • Pathology

Background:

  • Chronic maxillary atelectasis (CMA) involves reduced maxillary sinus volume due to inward bowing of sinus walls.
  • It is likely caused by maxillary ostium obstruction, leading to negative sinus pressure.

Purpose of the Study:

  • To investigate the epidemiology, pathogenesis, and treatment of Chronic Maxillary Atelectasis.
  • To analyze radiographic and clinical findings in patients with CMA.

Main Methods:

  • Retrospective study of twelve patients meeting radiographic criteria for CMA.
  • Surgical treatment involved creating a middle meatal antrostomy to restore sinus ventilation.

Main Results:

  • Patients were equally divided by sex, with an average age of 25; five were under 18.

  • Most patients presented with chronic sinonasal complaints; two had silent sinus syndrome.
  • First reports of CMA associated with benign nasal tumors and post-nasal packing cicatrization were noted.

    • Conclusions:

    • CMA is a rare and potentially underestimated condition, particularly in pediatric populations.
    • Various conditions causing ostial occlusion can lead to CMA.
    • Endoscopic restoration of maxillary sinus ventilation is the recommended treatment.
