The purpose of this study was to evaluate the clinical and radiographic characteristics of idiopathic bone cavity (IBC) to determine the effect of surgical intervention on the process of healing.
All cases diagnosed with IBC during the period of 2011 to 2020 at our Department of Oral and Maxillofacial Surgery were searched. Ninety cases were retrieved. The features evaluated were sex, age, contour of the lesion, number of teeth involved, site, history of trauma, and postoperative healing pattern. The significance of differences was assessed by Mann-Whitney U test and chi-square test.
The female:male ratio showed no predilection toward either sex (0.9:0.8). The mean age of the collected sample was 22.05±14.38 years, and the age ranged from 10 to 58 years. All cases presented in the mandible and showed well-circumscribed radiolucency. Margins were either scalloped or round in shape, and the size varied from one tooth to six teeth involvement. Seventy cases involved three or fewer roots. Three cases showed bilateral lesion. Four cases had a history of trauma at the area of the lesion. Fifty-one cases were followed for six months after surgery, and all showed increased bone density at the lesion.
There is no definitive radiological or clinical feature of IBC. Considering the diversity of clinical and radiological features, such a diagnosis relies primarily on surgical findings of an empty bone cavity with no epithelial lining. Our data suggest that surgical intervention be the first choice of treatment as opposed to observation.
本研究旨在评估特发性骨腔（IBC）的临床和影像学特征，以确定手术干预对愈合过程的影响。
检索2011年至2020年期间在我院口腔颌面外科诊断为IBC的所有病例。共检索到90例。评估的特征包括性别、年龄、病变轮廓、受累牙齿数量、部位、创伤史和术后愈合模式。采用Mann-Whitney U检验和卡方检验评估差异的显著性。
男女比例无明显性别倾向（0.9:0.8）。收集样本的平均年龄为22.05±14.38岁，年龄范围为10至58岁。所有病例均在下颌骨出现，表现为边界清晰的透射区。边缘呈扇贝形或圆形，大小从累及一颗牙齿到六颗牙齿不等。70例累及三个或更少牙根。3例表现为双侧病变。4例在病变区域有创伤史。51例术后随访6个月，所有病例病变部位骨密度均增加。
IBC没有明确的影像学或临床特征。考虑到临床和影像学特征的多样性，这种诊断主要依赖于无上皮衬里的空骨腔的手术发现。我们的数据表明，与观察相比，手术干预应作为首选治疗方法。
