Continuation of unilateral nasal discharge
The failure of dental sinusitis cases to resolve following exodontia may be related to one of the above described alveolar disorders, but is much more likely to be caused a residual sino-nasal problem (Dixon et al . 2019). Such cases should have the affected alveolus examined and, if it contains sequestrae and/or is infected, or if it has a communication with the sinus, these disorders should be treated. However, the more likely causes for non-response of dental sinusitis are the presence of inspissated exudate or bone sequestrae in the affected sinuses or intercurrent nasal disease including nasal conchal bulla infections (Dixon et al . 2019, 2021).
