Abstract
OBJECTIVE: This study aimed to propose appropriate management for odontogenic chronic rhinosinusitis. METHOD: Thirty-one adult patients with odontogenic chronic rhinosinusitis undergoing maxillary extraction were retrospectively analysed. Patients with (n = 21) and without (n = 10) oroantral fistula on computed tomography were classified. Functional endoscopic sinus surgery was performed when sinusitis did not improve after extraction. The critical indicators for surgical requirement in the management of odontogenic chronic rhinosinusitis were analysed. RESULTS: Sinusitis significantly improved after extraction in both groups. Patients without oroantral fistula had significantly more severe remnant sinusitis than those with oroantral fistula after extraction on computed tomography (p = 0.0037). The requirement for functional endoscopic sinus surgery was statistically significant for patients without orofacial fistula over those with orofacial fistula (p < 0.0001). The surgical improvement ratio was 93 per cent. CONCLUSION: The absence of oroantral fistula and severe sinusitis can be critical indicators for the requirement of functional endoscopic sinus surgery after extraction in the management of odontogenic chronic rhinosinusitis.
