The maxillary sinus ( maxillary sinus , maxillary sinus , maxillary cavity ; lat. Sinus maxillaris , ust. Lat. Sinus Highmori ) - paired paranasal sinus , occupying almost the entire body of the maxillary bone . The maxillary sinus is lined from the inside with a thin mucous membrane with ciliated epithelium , poor in goblet cells, vessels, and especially nerves; in this regard, diseases of the maxillary sinus (hyperplastic and exudative sinusitis , cysts , tumors , foreign bodies, etc.) can be asymptomatic for a long time. The maxillary sinus communicates with the nasal cavity through an opening on the inner surface of the maxillary bone, is normally filled with air ( pneumatized ). The lower wall of the maxillary sinus is thin, which contributes to the development of a odontogenic inflammatory process, the ingress of filling material into the sinus during dental fillings, etc.
Content
Walls of the maxillary sinus
The maxillary sinus has 5 walls:
- Top
- Lower
- Medial
- Front
- Posterior
Anesthesia
Anesthesia of the walls of the sinus is achieved with various methods of local anesthesia:
- During infraorbital anesthesia, anesthesia of the mucous membrane and bone tissue of the anterior, posterior, upper and lower sinus walls occurs.
- When conducting tubal anesthesia, anesthesia of the mucous membrane and bone tissue of the posterior sinus wall occurs.
Etymology
It was named after the English physician Nathaniel Gaimor ( 1613 - 1685 ), who first described her illness.
