Experimental group received diode laser for local irradiation therapy??the control group received drug treatmemt with rhEGF gel until ulcer healing. The course of treatment was one week. Results    Compared with control group??the experimental group has more obvious reduction of pain from baseline values??shorter median healing time and better efficacy. The differences were statistically significant??P??0.05??. There was no statistical difference on recurrence rate ??P > 0.05??. However?? within the next one month??there was no recurrence on treatment areas in experimental group. Conclusion    Diode laser treatment for RAU proves to be more stable and lasting in pain relieving and proves to be more obvious in accelerating healing time. Recurrence rate also can be reduced in the same area in short term. Laser therapy is more effective in the treatment of RAU compared with the rhEGF gel.

Partial superficial parotidectomy as the method of choice for treating pleomorphic adenomas of the parotid gland

We present our experience of 156 patients with parotid pleomorphic adenomas who were treated from 1995 to 2009 by partial superficial parotidectomy. In each case the main trunk of the facial nerve was identified and dissected. Only the division of the nerve adjacent to the tumour was dissected, and only the parotid tissue surrounding the tumour was excised. The results were satisfactory, as no patient developed permanent partial or total facial nerve paralysis, and transient paresis was noticed in only 23 patients (15%). Only one tumour recurred, and Frey syndrome developed in only 6 patients (4%). Enucleation was required in 55 patients (35%) because the tumour was so close to the branches of the facial nerve. Partial superficial parotidectomy is a safe treatment for parotid pleomorphic adenomas with relatively few postoperative complications. When it is done by experienced surgeons no permanent deficits are likely, it has low rates of recurrence, and gives excellent aesthetic results.     

A meta-analysis of the pros and cons of partial superficial parotidectomy versus superficial parotidectomy for the treatment of benign parotid neoplasms

ObjectivesSalivary gland tumors are predominantly benign and frequently localized in the parotid gland (P). The treatment consists primarily of surgical removal; however, the appropriate extent remains a subject of debate. In suitable tumors, superficial parotidectomy (SP) may be substituted for less invasive partial superficial parotidectomy (PSP) (I C). This systematic review analyzed the available literature, comparing PSP and SP with regards to several postoperative outcome parameters (O).Materials and methodsEstablished medical databanks were screened for articles evaluating outcomes of PSP compared with SP, published between 1955 and 2019. These data were assessed by pooled risk and odds ratios via meta-analysis.Results11 studies with 1272 patients were included. There was no significant difference in tumor recurrence between PSP and SP (primary outcome). Furthermore, no differences in the occurrence of permanent facial nerve paralysis (FNP), salivary fistula, great auricular nerve analgesia, or hematoma were observed between the groups. However, PSP displayed significantly reduced rates of transient FNP, Frey's syndrome, scar deformity, and xerostomia, as well as shorter surgical time, compared with SP (secondary outcomes).ConclusionBased on these data, PSP can be recommended as a surgical technique for the treatment of superficially located, small, benign parotid tumors.     

腮腺多形性腺瘤手术方式的改良

目的：探讨改良腮腺多形性腺瘤手术方式的临床应用效果。方法：采用改良手术方式,切除腮腺多形性腺瘤62例,观察术后并发症。结果：62例术后均有不同程度面瘫,于术后2周～3个月内恢复正常,耳垂皮肤感觉减弱,于术后2月内恢复正常,无涎瘘发生,随访2～10年,Frey综合征2例,无肿瘤复发,术后术区无凹陷,切口疤痕隐蔽。结论：改良术式切除腮腺多形性腺瘤,与传统术式相比,能达到同样疗效,但具有保存耳大神经,胸锁乳突肌瓣修复术后缺损便利,术后Frey综合征发生率低,术区无凹陷畸形,切口隐蔽等优点。     

Comparison of postoperative complications and facial nerve recovery rates after conventional and partial superficial parotidectomy of benign parotid tumours: a prospective study

The aim of this study was to compare postoperative complications and facial nerve (FN) recovery rates between conventional superficial parotidectomy (CSP) and partial superficial parotidectomy (PSP) as surgical treatment for benign parotid tumours. A prospective study was conducted on 55 consecutive patients who underwent either CSP (n = 35) or PSP (n = 20) for benign parotid tumours. The primary outcomes were FN injury, FN recovery rates, and Frey syndrome. Secondary outcomes were operative time, hospital stay, sialocele, haematoma, and auricular numbness. The degree of FN injury was evaluated at 1 week, 1, 3, 6, and 12 months postoperative using the House–Brackmann grading system. Frey syndrome was assessed using a subjective clinical questionnaire and objective Minor starch–iodine test. No patient in either group experienced permanent FN paralysis. There was a significantly higher incidence of temporary FN weakness in the CSP group (P = 0.007). The respective FN recovery rates at 1, 3, 6, and 12 months were 60%, 88.6%, 94.3%, and 100% in the CSP group and 90%, 95%, 100%, and 100% in the PSP group. No significant difference was observed between the groups regarding the incidence of Frey syndrome, sialocele, and haematoma. The operative time and hospital stay were both shorter in the PSP group. Although the PSP is a more conservative procedure with significantly reduced FN injury, operative time, and hospital stay compared to CSP, the CSP procedure shows a comparable FN recovery rate to the PSP.     

腮腺多形性腺瘤中BMP-2基因的表达及意义
