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]
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.
OAF is a complication of oroantral communication. Other complications may arise if left untreated. For example: Candidal infection [10] [11] Chronic maxillary sinus infection of bacterial origin [12] Osteomyelitis [13] Rhinosinusitis [14] Sinus pathology [10] Hence, OAF should be dealt with first, before treating the complications.
Traditionally the treatment of acute maxillary sinusitis is usually prescription of a broad-spectrum cephalosporin antibiotic resistant to beta-lactamase, administered for 10 days. Recent studies have found that the cause of chronic sinus infections lies in the nasal mucus, not in the nasal and sinus tissue targeted by standard treatment.
Treatment is typically with steroids, often in the form of a nasal spray. [1] If this is not effective, surgery may be considered. [1] The condition often recurs following surgery; thus, continued use of a steroid nasal spray is often recommended. [1] Antihistamines may help with symptoms but do not change the underlying disease. [1]
Silent sinus syndrome most often affects the maxillary sinus, usually with a collapse of the orbital floor. It may also affect the frontal sinus or the ethmoid sinus. When the maxillary sinus is involved, the inferior oblique muscle may be damaged. [1] The cause of silent sinus syndrome is not well understood.
Expansion of the cyst causes erosion of the floor of the maxillary sinus. As soon as it enters the maxillary antrum, the expansion rate increases due to available space for expansion. Performing a percussion test by tapping the affected teeth will cause shooting pain. This is often clinically diagnostic of pulpal infection. [citation needed]
