Abstract

Objective: This study examined the prevalence, surgical treatment strategies, postoperative complications and recurrence rates of odontogenic cysts in the University Hospital in Örebro. Material and Methods: Data were retrieved from patient’s records of 234 patients who received the diagnosis odontogenic cyst during the years 2011-2021 at the maxillofacial surgery clinic in Örebro. The collected data covered patient gender and age, health declaration, presence of symptoms, tobacco use, diagnosis, localization of cyst, size of the cyst, radiographical examination, date of surgery, histopathological diagnosis, treatment, recurrence, reported complications and if hospitalization was needed. Results: A total of 211 patients were included in the study. 87.7% of the patients were diagnosed with ICD-10 code K099 and 12.3% with K092. The most common odontogenic cyst was dentigerous cyst (25%), followed by the radicular cyst (20.5%) and the third most common cyst (20%) was the Odontogenic Keratocyst (OKC). The most common treatment reported was tooth extraction in combination with cyst enucleation (45.9%) followed by only enucleation (33.5%). Recurrence was reported in 17 of the cases and of these, 11 were OKC. Recurrence was most common the first three years. Postoperative complications were reported in 37% of the cases and the most common complications were postoperative infections. Conclusion: The prevalence, surgical treatment strategies, postoperative complications and recurrence rates of odontogenic cysts in the University Hospital in Örebro is similar to data presented in other studies. A large variation in the diagnosis of cysts has been noted, which is why the authors have suggested a simplified classification system to improve the quality of future research and simplify the classification for the odontogenic cysts in the clinic.
