  • Each opens into the anterior part of the corresponding middle nasal meatus of the nose through the frontonasal duct which traverses the anterior part of the labyrinth of the ethmoid. (wikipedia.org)
  • Through its copious mucus production, the sinus is an essential part of the immune defense/air filtration carried out by the nose. (wikipedia.org)
  • maxillary
  • Four signs and symptoms are the most helpful in predicting acute bacterial rhinosinusitis: purulent nasal discharge, maxillary tooth or facial pain (especially unilateral), unilateral maxillary sinus tenderness, and worsening symptoms after initial improvement. (aafp.org)
  • Four signs and symptoms are probably helpful in diagnosing ABRS: purulent nasal discharge, maxillary tooth or facial pain (especially unilateral), unilateral maxillary sinus tenderness, and worsening symptoms after initial improvement. (aafp.org)
  • Sinus development begins in the womb, the maxillary and ethmoid sinuses are present at birth. (wikipedia.org)
  • acute
  • Sinus radiography and ultrasonography are not recommended in the diagnosis of uncomplicated acute bacterial rhinosinusitis, although computed tomography has a role in the care of patients with recurrent or chronic symptoms. (aafp.org)

  • Endonasal approach into the frontal sinus in children with acute and chronic frontal sinusitis without the usage of surgical optics is not successful, because in this case the operation is performed almost blindly and technically difficult even in adults. (wikipedia.org)
  • infection
  • Infection of the frontal sinus causing sinusitis can give rise to serious complications, as it is in close proximity to the orbit and cranial cavity (orbital cellulitis, epidural and subdural abscess, meningitis). (wikipedia.org)
