口腔的感觉障碍包括感觉缺失(麻木)、感觉减退、感觉过敏和感觉异常。感觉异常是感觉障碍较常见的主诉,出现混合性症状。一般,其特点为麻木感伴有烧灼感、针刺感和蚁走感。在判定感觉异常的原因时,除系统性痰病以外,还应该考虑局部因素,如病毒感染、多发性硬化症、梅毒和转移性恶性肿瘤。作者复习61例面部麻木的文献资料,其中83%的病例找出明确的病因。最常见的情况是注射后感觉异常,可能是由于神经鞘内出血的压迫或沾有化学消毒剂的针头刺激引起的。骨
Oral sensory disturbances include loss of sensation (numbness), loss of sensation, sensory hypersusceptibility and sensory abnormalities. Feeling abnormalities is the more common complaint of sensory disturbances, with mixed symptoms. In general, it is characterized by numbness associated with burning sensation, acupuncture and ants feeling. In determining the cause of abnormalities, in addition to systemic sputum, local factors such as viral infections, multiple sclerosis, syphilis and metastatic malignancies should also be considered. The authors reviewed 61 cases of facial numbness in the literature, of which 83% of the cases identified a clear cause. The most common condition is an abnormal sensation after injection, possibly due to compression of the intrathecal or needle irritation with chemical disinfectant. bone
