Maxillary sinusitis is common due to the close anatomic relation of the frontal sinus, anterior ethmoidal sinus and the maxillary teeth, allowing for easy spread of infection. Differential diagnosis of dental problems needs to be done due to the close proximity to the teeth since the pain from sinusitis can seem to be dentally related. [ 1 ]
The four paired paranasal sinuses are the frontal, ethmoidal, maxillary, and sphenoidal sinuses. The ethmoidal sinuses are further subdivided into anterior and posterior ethmoid sinuses, the division of which is defined as the basal lamella of the middle nasal concha .
Odontogenic sinusitis is a type of sinusitis (inflammation of the sinuses), specifically caused by dental infections or procedures. [1] Comprising approximately 10-12% of all chronic sinusitis cases, this condition primarily affects the maxillary sinus , which is in close proximity to the upper teeth .
Caldwell-Luc surgery, Caldwell-Luc operation, also known as Caldwell-Luc antrostomy, and Radical antrostomy, is an operation to remove irreversibly damaged mucosa of the maxillary sinus. It is done when maxillary sinusitis is not cured by medication or other non-invasive technique. The approach is mainly from the anterior wall of the maxilla bone.
Odontogenic sinusitis is an inflammatory condition of the paranasal sinuses that is the result of dental pathology, most often resulting from prior dentoalveolar procedures, infections of maxillary dentition, or maxillary dental trauma. [6] Infections associated with teeth may be responsible for approximately 20% of cases of maxillary sinusitis ...
Maxillary sinuses are more radiolucent than orbits. Maxillary sinusitis [2] Differentiating pathology in maxillary sinus. Maxillary sinus shows radiopacity. [2] Mucous membrane shows thickening. [2] Air-fluid level may be observed if the radiograph is taken in "head-up" position. [2] It is not seen in radiograph taken in lying down position.
Fungal sinusitis or fungal rhinosinusitis is the inflammation of the lining mucosa of the paranasal sinuses due to a fungal infection. [1] [2] It occurs in people with reduced immunity. The maxillary sinus is the most commonly involved. Fungi responsible for fungal sinusitis are Aspergillus fumigatus (90%), Aspergillus flavus, and Aspergillus ...
The maxillary sinus is known for its thin floor and close proximity to the posterior maxillary (upper) teeth. [ 1 ] [ 6 ] The extraction of a maxillary tooth (typically a maxillary first molar which lies close to the lowest point of antral floor although any premolar or molar can be affected) is the most common cause of an OAC (which can then ...
