Oroantral fistula (OAF), also termed oroantral communication, is an abnormal condition in which there is a communicating tract between the maxillary sinus and the oral cavity. The most common causes of this pathological communication are known to be dental implant surgery and extraction of posterior maxillary teeth. The purpose of this article is to describe OAF; introduce the approach algorithm for the treatment of OAF; and review the fundamental surgical techniques for fistula closure with their advantages and disadvantages. The author included a thorough review of the previous studies acquired from the PubMed database. Based on this review, this article presents cases of OAF patients treated with buccal flap, buccal fat pad (BFP), and palatal rotational flap techniques.

To evaluate criteria, indications, and prognosis of the various reconstructive methods on the patients with intraoral soft tissue defect who had been treated at Dept. of Oral and Maxillofacial Surgery, Pusan National University Hospital from 2003 to 2005, we have reviewed the clinical data of the patients and analysed. The results were as follows: 1. Tongue flaps have been mainly applied on anterior portion of palate and maxilla. The survival rate was high percent, but the cooperation of patient was inevitable for the success. 2. Palatal mucosa rotational flaps were available on relative large defect on palate, oroantral fistula site. The side effect was a scaring band from secondary healing on denuded donor palate site. Sometimes the band came to be a hinderance to swallowing, phonation. 3. Forearm free flap was a workhorse flap for everywhere in intraoral defects. We had used the flap on cheek, floor of mouth, tongue without any significant complications. But the application of the flap was required for long operation time, which was disadvantageous to the old, weak patients. 4. Cervical platysmal flap could be easily applicable for buccal cheek, floor of mouth after excision of the cancer lesion. The design of the flap could be made simultaneously on neck dissection, but the danger of cancer remnants on the flap always might be remained. 5. Buccal fat pad pedicled flap must have been a primary flap for repair of oroantral fistula especially on posterior maxilla. The flap survival will be expected if the considerations for above reconstructive methods on site, size, condition of defects primarily could be made.

The pleomorphic adenoma is well recognized as the most common salivary neoplasm. We examined 49 patients who had received surgical excision of the pleomorphic adenoma from 1989 to 1998 with over 5 years follow-up period. We retrospectively evaluated the patients' age, sex, chief complaints, surgical methods, and recurrence or complication rates after analysis of one's clinical and surgical records. The results are as follows : 1. There were 15 cases in parotid gland, 23 cases in palate, 8 cases in submandibular gland, and 3 cases in cheek. The ratio of male to female was 1 : 1.13. The mean age was 44. The tumor of submandibular gland occurred in more younger age than that of other salivary gland. 2. In 15 patients of parotid pleomorphic adenoma, there was 1 case(6.7%, 1/15) of recurrence. That was transformed into the malignant pleomorphic adenoma after 4 years of first surgery. We performed superficial parotidectomy of 9 cases(56.2%, 9/16), total parotidectomy of 6 cases(37.5%, 6/16), and radical parotidectomy of 1 case(6.3%, 1/16). 3. We used the rotational Sternocleidomastoid muscular flap to cover the exposed facial nerve in 12 cases(75%) after parotidectomy(7 cases of superficial parotidectomy and 5 cases of total parotidectomy). We could see 3 cases(18.7%) of facial nerve palsy and 1 case(6.3%) of Frey's syndrome after parotidectomy. We examined Frey's syndrome in only 1 case which was not used SCM muscular flap after parotidectomy. 4. In 23 patients of palatal pleomorphic adenoma, there were 2 cases(8.7%) of recurrence. In recurrence cases, We performed re-excision after 4 and 5 years of first surgery, respectively. We preserved partial thin overlying palatal mucosa during tumor excision in 5 cases(20%), which were proved as benign mixed tumor in preoperative biopsy. That mucosa-preserved cases had thick palatal mucosa, did not show mucosa ulceration and revealed well encapsulated lesions in preoperative CT. 5. In palatal tumors, we could see the 13 cases(52%) of bony invasion in preoperative CT views and the 4 cases(16%) of oro-nasal fistula after tumor excision. In two cases of recurrence, one(20%, 1/5) was in palatal mucosa-preserved group and the other(5.5%, 1/18) was in palatal mucosa-excised group. 6. We excised tumors with submandibular glands in the all cases of submandibular pleomorphic adenoma. There was no specific complication or recurrence in these cases. 7. After excision of the cheek pleomorphic adenomas, we could not see any complication or recurrence.

식욕부진, 호흡부전, 또는 비출혈을 보이는 두 마리 개가 내원하였다. 신체검사에서 호흡곤란, 개구호흡 및 커다란 구개 종양을 확인하였다. 신체검사 중 2 번 증례에서 호흡부전으로 인한 심정지가 발생하였고 심폐소생술과 산소 공급을 통해 안정화 되었다. 1 번 증례의 CT 촬영에서 경구개 연구개를 포함하는 구강 인두, 인두 내 입구, 인후두 부위의 종양을 확인하였다. 연하곤란 및 호흡부전 개선을 위해 보호자 동의 하에 완화 수술을 결정하였다. 종양 제거 후 발생한 결손 부위 재건을 위해 구강 내 점막을 사용하여 회전 및 전진 피판술과 양측 90o 자리바꿈 피판술을 1 및 2 번 증례에 각각 적용하였다. 조직 검사 결과, 두 마리의 개 모두에서 무멜라닌 색소성 흑색종이 진단되었다. 수술 후 7 일째 두 마리 모두에서 정상 연하와 호흡이 확인되었다. 수술 후 4 주째 1 번 증례의 수술 부위에서 재발된 종양이 관찰되었다. 보호자가 추가적인 치료를 원하지 않았고, 연락 두절로 인하여 수술 후 2 개월 이후의 확인은 불가능하였다. 수술 후 3 주째 2 번 증례의 신체검사 및 방사선 촬영에서 국소적인 재발 및 전이는 확인 되지 않았다. 수술 후 7 주째 유선상으로 확인한 결과, 2 번 증례에서 원인불명의 갑작스러운 사망이 확인되었다.
