Treatment for oroantral communications of 170 cases
Poster Session for the transplanted teeth. Total tooth movement including transplanted was initiated 6 months after the surgery. Subsequently, orthognathic treatment was performed because the right upper central incisor did not move due to dental ankylosis. A dentoalveolar segment including the right upper central incisor was moved en bloc to the best possible position with ideal inclination. Finally, a good occlusion including the transplanted teeth and the moved dentoalveolar segment was created. Orthodontic treatment including the transplanted tooth after healing can create an ideal dental arch and good occlusion. We consider that best healing term is 6 months after transplantation because of regeneration of the periodontal membrane and the alveolar bone. If dental ankylosis is found, a dentoalveolar osteotomy should be performed to create a good occlusion. References: 1. Gillepsie MB, Marshall DT, Day TA, Mitchell AO, White DR, Barredo JC.

POSTER 54 A case of esophageal perforation by miss-swallowing of partial denture A. Muta: Kumamoto University, Kumamoto University, M. Shinohara, A. Hiraki, H. Nakayama, H. Kamahara, K. Sagishima, D. Niimori, T. Tashiro, Y. Kinoshita The most of accidental miss-swallowing of dental protheses are seen in patients with partial dentures covering some teeth, crowns and inlays. In most cases, they can be taken out easily or be spontaneously discharged. However, the large size of dental prostheses may damages pharyngeal and esophageal mucosa. A 57-year-old male was diagnosed as miss-swallowing of a foreign body in a local clinic and referred to our emergency department. CT scans revealed the existence of a large size of dental prosthesis in upper esophagus with perforation and indicated the possibility of mediastinitis. Therefore, surgical removal of the prothesis and drainage under general anesthesia were performed, and then he was sent to ICU with endotracheal intubation. The extubation was undergone on 11th hospital day. Subsequently, the patient showed symptomatic epileptic seizure and salivary flow to the lungs was found because of nerve paralysis. He was complicated with pneumonia so we follow up with antibiotics on 14th hospital day. Pooling and flow to the lung of saliva continued and SpO2 was decreased. Therefore, we inserted a transtracheal catheter and it was useful for suctioning phlegm and improving oxygenation better. He left ICU on 18th hospital day. We herein report this case with a review of literature.

POSTER 55 Treatment for oroantral communications of 170 cases N. Yakushiji: Kinki Central Hopital An oroantral communication (OAC) is an abnormal communication between the oral cavity and the maxillary sinus. Such a communication may cause ingress of microorganism from the oral cavity into the antrum leading to maxillary sinusitis and develop into an oroantral fistula (OAF). Many techniques have been proposed for the closure of OAC, and the best treatment method for OAC is still debated. In the various cases of struggling to close is seen here and there, we have achieved good results of the surgical repair of OAC in our department. We studied 170 cases (male 97 cases, female 73 cases) of the closure of OAC and OAF during the five-and-a-half year of April 2008 to October 2013, which cases were all performed in our department. In each case, we examined the patient’s age, sex, etiology, presence or absence of maxillary sinusitis. Then, we presented the surgical procedure of surgical closures using figures that are performed in our department actually. As a result, in 169 cases out of the 170 cases, good treatments are shown. In one case, suture dehiscence was observed and a second surgical procedure was necessary. The average age was 47.8 years, minimum age is 14 years, and maximum age was 81 years old. The gender distribution age, the number of cases was the highest in the 60s men and 30s women. The most frequent cause of OAC was the extraction of the first upper molar, followed by second upper molar, third upper molar, second upper premolar, first upper premolar, and upper canine. Sinusitis was observed in 87 patients. These cases were treated after the maxillary sinusitis has been cured. We have used buccal advancement flap technique in all cases. We show below a typical case of the surgical closure of OAC. In this case, a broad-based trapezoid mucoperiosteal flap was created. After cleaning the communication, the alveolar bone was smoothed, and the flap added relaxation incision was advanced and sutured to the palatal tissue by means of mattress sutures. After the operation, a surgical packing or a surgical splint was prepared and used for 1 week. In conclusion, we suggested that our surgical procedure have achieved a good performance. References: 1.
