[Evaluation of 79 patients with oroantral and oronasal fistula]

Various methods for closure of oroantral communication [OAC] and oronasal communication [ONC] have been reported. These are different based on the skill of surgeon, type of communication, size and location of defect and other factors. The purpose of this study was to evaluate the etiologic factors, location, type of treatment and surgical results in patients with oronasal and oroantral communications. In this descriptive study, between 2005-2007. 79 patients with OAC or ONC were evaluated for aforementioned factors. The data were statistically analyzed by Chisquare and Odd's ratio tests. Seventy nine patients including 9 patients with ONC and 70 patients with OAC were studied. The main etiologic factor for both OAC and ONC was tooth extraction. The surgical technique most frequently used for treatment of both OAC and ONC was suturing. Surgical failure occurred in 4 cases with OAC and 3 cases with ONC after first surgery. According to the results of this study, tooth extraction was the most etiologic factor for OAC and ONC. Suturing for small communications and use of a buccal fat pad flap for larger defects, seem to be the best choices for treatment

[Evaluation the bleeding in patients maintained on oral anticoagulant therapy without interruption of their treatment after use of tranexamic acid mouthwash]

Today many patients with some reasons need the use of anticoagulant drugs ,that interruption of this drugs may be dangerous. The purpose of this study was to evaluate the use of tranexamic acid 5% mouthwash to control hemostasis in patients therapeutically anticoagulant medication undergo dental extraction without interruption of medication. This study was a descriptive study and the data collection method was direct observation. A total of 55 patients undergone 167 dental extraction without interruption of oral anticoagulant medication, were required to rinse with 10 ml of a tranexamic acid 5% mouthwash 4 times a day for 7 days postoperatively. Dental extraction was carried out by two surgeon. Data were analyzed using SPSS statistical software and descriptive analyzed done. Of 55 patients treated, 1 presented with postoperative bleeding on the third day after operation [1/8%]. In this patient international normalized ratios was grossly elevated on the day of the bleeding [6.1]. This study supports the consensus that simple dental extraction in patients maintained on oral anticoagulant therapy with use tranexamic acid 5% mouthwash, can be performed without reduction or intruption dose of anticoagulant medication, and hemostas occurred well
