Anatomy and physiology
The maxillary sinus is part of a series of paranasal sinuses, which includes the frontal, ethmoid, and sphenoid sinuses. These pneumatic cavities surround the nasal cavity and are in close approximation to the orbital walls and dura mater of the anterior cranial fossa. The maxillary sinus is the first of the paranasal sinuses to develop in the third month of fetal life. A primary pneumatization process occurs as an invagination of nasal epithelium off the ethmoid infundibulum, a recess between
Management
Treatment of odontogenic sinusitis usually requires a combination of medical and surgical management. Elimination of the source (eg, removal of a foreign tooth root from the sinus or treatment of an infected tooth by extraction or root canal therapy) is required to prevent recurrence of the condition. Medical management often includes a 7- to 14-day course of oral antibiotics with adequate sinus and oral flora coverage. Antibiotics may be combined with use of systemic nasal decongestants and 2
Summary
Odontogenic sinusitis is a well-recognized condition and accounts for approximately 10% to 12% of cases of maxillary sinusitis. An odontogenic source should be considered in patients with symptoms of maxillary sinusitis who give a history positive for odontogenic infection or dentoalveolar surgery or who are resistant to standard sinusitis therapy. Diagnosis usually requires a thorough dental and clinical evaluation with appropriate radiographs. Common causes of odontogenic sinusitis include

Various odontogenic pathologies can cause OMS, including pulpitis, periapical lesions, periodontitis, oroantral fistulas or foreign bodies in the sinus related to dental treatment [1,2,11,12]. OMS following dental procedures are increasing [1,2].
