Methods: This is a cross sectional study. Patients with oro-facial squamous cell carcinoma attending the Oral Pathology and Radiotherapy clinics of the University College Hospital, Ibadan, Nigeria were included. Seventy subjects comprising 22 patients with untreated OSCC, 18 patients with OSCC receiving treatment and 30 healthy, age and gender matched individuals were included. Serum and salivary samples from the participants were analysed for IgA levels using ELISA technique. Results: The mean value of serum IgA in OSCC patients receiving treatment was significantly lower compared with healthy controls (p = 0.03), while no significant difference was observed comparing untreated OSCC patients with treated and healthy controls. The salivary IgA levels did not show any significant difference between the three groups (p = 0.73). Also, there was no correlation between serum and salivary levels of IgA among the subjects. Conclusions: Serum IgA appeared to be better index than salivary IgA levels in monitoring response to treatment in patients with oro-facial carcinoma.展开更多

目的：探讨颜面部钙化上皮瘤的有效切除范围及缩小手术切口的疗效和临床意义。方法2012年1月至12月我们收治颜面部单发钙化上皮瘤39例，手术切除范围包括包膜内肿物切除、肿物连同包膜完整切除、包膜外1～2 mm 切除、全层皮肤连同肿物...目的：探讨颜面部钙化上皮瘤的有效切除范围及缩小手术切口的疗效和临床意义。方法2012年1月至12月我们收治颜面部单发钙化上皮瘤39例，手术切除范围包括包膜内肿物切除、肿物连同包膜完整切除、包膜外1～2 mm 切除、全层皮肤连同肿物挖除（2～4 mm），手术方式为普通切口，设为普通切口组；2013年1月至12月收治颜面部单发钙化上皮瘤45例，切除范围包括包膜内切除、连同包膜完整切除，手术方式为微小切口，设为微小切口组。比较两组肿物最大直径和切口长度，并从病理特点探讨其有效切除范围的依据。结果两组84例均恢复良好，无一例复发。病理特点：钙化上皮瘤瘤体周边界限清晰，其包膜完全为纤维结缔组织假性包膜，无上皮或内皮结构，包膜周边即正常的皮下组织结构，无增殖的瘤细胞。免疫组化：Ki67（－）。两组肿物直径比较，差异无统计学意义（P ＞0.05）；切口长度比较，差异有统计学意义（P ＜0．05）。术后微小切口组瘢痕小，外形美观，患儿及家属满意度高。结论钙化上皮瘤经临床检查即可诊断，术中无需切除过多的组织，只要将钙化团块完全切除即可，采用微创小切口方法，疗效确切，术后瘢痕不明显，外形美观，患者满意度高。展开更多
