Objective:
To investigate the necessity of subsequent dental treatment for patients with odontogenic sinusitis (OS) after endoscopic sinus surgery (ESS).
Methods:
OS patients who received ESS from January 2018 to May 2022 were eligible. Demographic data, medical history, Lund-Mackay (LM) computed tomography (CT) score, Lund-Kennedy (LK) endoscopic score, and OS-specific CT score were recorded and analyzed. All patients were followed up for 6 months after surgery.
Results:
A total of 48 patients (30 males and 18 females) were enrolled. A total of 35 cases (72.9%) were caused by dental diseases (periapical periodontitis), and 13 cases (27.1%) were caused by iatrogenic factors (including tooth extraction or implantation). The overall treatment success rate was 97.9%, and the success rates in the dental disease OS group (97.1%) and the iatrogenic OS group (100%) were not significantly different (X2 = 0.329, P = .729). None of the patients in the dental disease group received treatment of the causative teeth within 6 months after the operation, except for one patient who received tooth extraction treatment 6 months after the operation.
Conclusion:
Without considering the impact of dental disease on patients' oral health, OS can be completely alleviated by ESS alone, even if no dental treatment is carried out after surgery.
