Maxillofacial trauma presents a complex problem due to the disruption of normal anatomy. In such cases, we anticipate a difficult oral intubation that may hinder intraoperative IMF. Nasal and skull base fractures do not advocate use of nasotracheal intubation. Hence, other anesthetic techniques should be considered in management of maxillofacial trauma patients with occlusal derangement and nasal deformity. This study evaluates the indications and outcomes of anesthetic management by retromolar, nasal, submental intubation and tracheostomy.
Of the 49 maxillofacial trauma cases reviewed, that required intraoperative IMF, 32 underwent nasal intubation, 9 patients had tracheostomy, 5 patients utilized submental approach and 3 underwent retromolar intubation.
Among patients who underwent nasal intubation, eight cases needed fiberoptic assistance. In retromolar approach, though no complication was encountered, constant monitoring was mandatory to avoid risk of tube displacement. Consequently, submental intubation required a surgical procedure which could result in a cosmetically acceptable scar. Though invasive, tracheostomy has its benefits for long term ventilation.
Intubation of any form performed in a maxillofacial trauma patient is complex and requires both sound judgement and considerable experience.
由于正常解剖结构的破坏,颌面创伤呈现出一个复杂的问题。在这种情况下,我们预计会出现困难的口腔插管,这可能会阻碍术中颌间固定。鼻骨和颅底骨折不主张使用经鼻气管插管。因此,在处理伴有咬合紊乱和鼻畸形的颌面创伤患者时,应考虑其他麻醉技术。本研究评估了经磨牙后、经鼻、经颏下插管和气管切开术进行麻醉管理的适应证和结果。
在回顾的49例需要术中颌间固定的颌面创伤病例中,32例行经鼻插管,9例行气管切开术,5例采用经颏下途径,3例行经磨牙后插管。
在经鼻插管的患者中,8例需要纤维支气管镜辅助。在经磨牙后途径中,虽然未遇到并发症,但必须持续监测以避免导管移位的风险。因此,经颏下插管需要进行手术,这可能会导致一条在美容上可以接受的瘢痕。气管切开术虽然具有侵入性,但对长期通气有其益处。
在颌面创伤患者中进行的任何形式的插管都很复杂,需要良好的判断力和丰富的经验。
