背景:当脸颊区域的面部肿块与临床怀疑为腮腺起源的高指数相关时,预防性腮腺切除术总是进行。我们报告了一例罕见的神经鞘瘤病例,该病例被怀疑是腮腺起源的,使用改良的Blair切口和浅表肌肌腱膜系统(SMAS)层折叠方法进行了成功的手术治疗。
方法:一名27岁的妇女到医院对一家公司进行评估,固定,非压痛肿块(2.5厘米×3.5厘米),位于右耳前方,1年的持续时间。对比增强的面部计算机断层扫描显示,低密度肿块粘附在右腮腺浅叶,临床怀疑副腮腺肿块的高指数。该患者计划接受肿块切除术和浅表腮腺切除术。她用改良的布莱尔切口做了手术,SMAS层向后折叠以重建缺损。组织病理学检查证实了神经鞘瘤的诊断。,我们没有观察到血肿等术后并发症,感染,或者面部表情异常.术后2个月切口瘢痕不明显,面部轮廓保持在受影响和未受影响的两侧之间没有任何差异。
结论:我们使用了改良的Blair切口和SMAS层折叠方法,在脸颊区域切除了一种罕见的神经鞘瘤并进行了浅表腮腺切除术后,获得了良好的美学效果。
BACKGROUND: When a firm facial mass in the cheek region is associated with a high index of clinical suspicion of its being of parotid gland origin, preventive parotidectomy is invariably performed. We report a rare
case of a schwannoma that was suspected to be of parotid gland origin in a patient, who underwent successful surgical management using a modified-Blair incision and superficial musculoaponeurotic system (SMAS) layer folding method.
METHODS: A 27-year-old woman presented to the hospital for evaluation of a firm, fixed, non-tender mass (2.5 cm × 3.5 cm), located anterior to the right ear, of 1 year\'s duration. Contrast-enhanced facial computed tomography revealed a well-encapsulated, low-density mass adherent to the superficial lobe of the right parotid gland, with a high index of clinical suspicion of an accessory parotid gland mass. The patient was scheduled to undergo resection of the mass and superficial parotidectomy. She underwent surgery using a modified-Blair incision, and the SMAS layer was folded posteriorly to reconstruct the defect. Histopathological examination confirmed the diagnosis of a schwannoma., and we observed no postoperative complications such as hematoma, infection, or abnormal facial expressions. The incision scar was unnoticeable 2 mo postoperatively, and the facial contour was maintained without any differences between the affected and unaffected sides.
CONCLUSIONS: We used a modified-Blair incision and SMAS layer folding method to achieve aesthetically good results following resection of a rare schwannoma with superficial parotidectomy in the cheek region.
