注射处顽固性疼痛是口腔局麻中最常见的并发症之一,而牙关紧闭却甚为少见。如果不能正确的治疗,就可以迁延为慢性期。本文拟通过复习解剖学,病理生理学并结合典型病例来说明如何处理牙关紧闭。下颌的阻滞或上颌后区的浸润麻醉进入颈肌、翼内肌、翼外肌和下齿槽神经、舌神经、上颌神经、以及颌内动脉及其分支、翼静脉丛所在的颞下凹(infratemporal fossa)内。这些对理解由于牙科手术麻醉后所致牙关紧闭的病理生理是重要的。病例报告: 病例1 患者为修复牙曾行4次下齿槽
Refractory pain at the injection site is one of the most common complications of oral anesthesia, while the occlusion is rare. If you can not correct treatment, you can postpone the chronic phase. This article intends to review the anatomy, pathophysiology and combined with typical cases to illustrate how to deal with the teeth closed. Mandibular blockage or maxillary posterior zone infiltration anesthesia enters the medial, lateral, and lateral alveolar, lingual and maxillary nerves, as well as the inferior foramen of the inferior vena cava and its branches infratemporal fossa. These are important for understanding the pathophysiology of occlusion due to dental closure following anesthesia. Case Report: Case 1 The patient had a lower alveolus 4 times for a prosthetic tooth
