Which method is successful in closureof acute oroantral communication? A retrospective study / ¿Qué método tiene éxito en el cierre de la comunicación oroantral aguda? Un estudio retrospectivo

ABSTRACT

Background: This study's purpose is to retrospectively evaluate the success of surgical methods used in treatingOroantral Communication (OAC).Material and Methods: This study was designed as a retrospective cohort study on patients who developed OACafter surgery maxillary posterior region. The records of patients previously treated with OAC were scannedthrough the hospital registry software. A data set was created by recording patients' age, gender, systemic dis-ease, etiological reasons, and surgical methods. The primary predictor variable was the surgical method usedto treat OAC. Other variables were age, gender, systemic disease and etiological reasons. The primary outcomewas oroantral fistula development after the first surgical intervention. The patients who were positive in clinicalexamination and Valsalva test on control days were considered unsuccessful. One-way analysis of variance andKruskal-Wallis tests were used for quantitative variables in more than two groups. Pearson chi-square test wasused to compare categorical data.Results: This retrospective cohort study was completed with 605 patients who met the study criteria among 95,883patients who underwent surgery in the maxillary posterior region. The incidence of OAC was 0.63%. The patientsconsisted of 238 female and 367 male patients. The mean age was 41.06±14.48 years. Buccal flap and Buccal FatPad methods were used most frequently in the treatment. While treatment was completed with the first surgicalintervention in 592 (97.85%) patients, OAF developed in 13 (2.15%) patients. No statistically significant relationexisted between surgical technique and OAF development (p>0.005). The success rate of the Buccal Flap methodwas 98.7%, and the Buccal Fat Pad method was 95.8%.(AU)
