Maxillary sinuses. Frontal sinuses, seen with an oblique view. Ethmoidal cells. Sphenoid sinus, seen through the open mouth. Odontoid process, where if it is just below the mentum, it confirms adequate extension of the head. The frontal sinus may not show the frontal sinus in detail. [1]
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 ]
Sinusitis, also known as rhinosinusitis, is an inflammation of the mucous membranes that line the sinuses resulting in symptoms that may include production of thick nasal mucus, nasal congestion, facial congestion, facial pain, facial pressure, loss of smell, or fever. [6] [7] Sinusitis is a condition that affects both children and adults.
Odontogenic sinusitis. 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. [2]
Because the maxillary posterior teeth are close to the maxillary sinus, this can also cause clinical problems if any disease processes are present, such as an infection in any of these teeth. These clinical problems can include secondary sinusitis, the inflammation of the sinuses from another source such as an infection of the adjacent teeth. [6]
Paranasal sinuses: 1. frontal sinuses, 2. ethmoid sinuses (ethmoidal air cells), 3. sphenoid sinuses, 4. maxillary sinuses. The exact cause of nasal polyps is unclear. [1] They are, however, commonly associated with conditions that cause long term inflammation of the sinuses. [8]
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 ...
Sinus disease often occurs in conjunction with, and in other instances may contribute to the development of nasolacrimal duct obstruction. Patients should be asked about previous sinus surgery, as the nasolacrimal duct is sometimes damaged when the maxillary sinus ostium is being enlarged anteriorly.
