This retrospective study analyzed the etiologic factors, location and treatments for patients with oroantral or oronasal communications (OAC or ONC). Data analysis extended to gender, age, etiology, location, type of treatment and short-term complications from January 1988 to May 2004. A total of 112 patients with 101 (90%) OAC and 11 (10%) ONC were included. The main etiology for OAC was tooth extraction (95%) with similar prevalence between right (49%) and left (51%) side. For ONC, pathological conditions (27%) and exodontia (27%) were the most prevalent. For the treatment of OAC, suture was the technique most frequently used (60%), followed by buccal fat pad (28%), buccal flap (9%), palatal flap (2%) and one dental transplant (1%). For ONC, the following treatments were used: suture (46%), buccal flap (36%) and palatal flap (18%). Failure to eliminate the communication occurred in six (6%) patients of the OAC group and three (27%) of the ONC group. The results confirm that tooth extraction was the most common etiologic factor for ONC and OAC. Suture, when the communication was small (3-5 mm), and the use of a buccal fat pad (100% successful), when a larger communication existed (>5 mm), seemed to be the two best choices for treatment.
这项回顾性研究分析了患有口腔上颌窦或口鼻相通（OAC或ONC）患者的病因、病变位置及治疗方法。数据分析涵盖了1988年1月至2004年5月期间患者的性别、年龄、病因、病变位置、治疗类型及短期并发症。总共纳入了112例患者，其中101例（90%）为OAC，11例（10%）为ONC。OAC的主要病因是拔牙（95%），右侧（49%）和左侧（51%）的患病率相似。对于ONC，病理状况（27%）和拔牙（27%）最为常见。对于OAC的治疗，最常使用的技术是缝合（60%），其次是颊脂垫（28%）、颊瓣（9%）、腭瓣（2%）和1例牙移植（1%）。对于ONC，采用了以下治疗方法：缝合（46%）、颊瓣（36%）和腭瓣（18%）。OAC组有6例（6%）患者和ONC组有3例（27%）患者未能消除相通情况。结果证实，拔牙是ONC和OAC最常见的病因。当相通较小（3 - 5毫米）时，缝合，以及当相通较大（>5毫米）时使用颊脂垫（成功率100%），似乎是两种最佳治疗选择。
