Management of retained foreign bodies in missile injuries of the maxillofacial region

This study evaluates 22 patients with retained foreign bodies in the maxillofacial region that were all caused by penetrating missile injuries. Surgical intervention for the retrieval of the foreign bodies was carried out in 20 patients through the existing wounds and through separate incisions; all patients were followed up for a minimum of 2 months during which all the complications were registered and managed. Preoperative imaging is a prerequisite for the accurate localization of the foreign body and the subsequent successful removal of it. All patients developed complications that were categorized in this study into those that result from the injury itself and those that occur because of the retrieval procedure, the latter category being mostly easily managed. In general, all foreign bodies in the maxillofacial region should be removed; the surgeon involved should weigh the benefits and the perils of the removal, and the patient should be well informed about the possibility of the failure of removal of the foreign body.     

颌面部非金属微小异物的超声定位及手术治疗

目的:应用超声对颌面部非金属微小异物进行诊断定位并引导手术摘取异物。方法:采用超声对18例患者7个解剖部位的8种微小非金属异物进行探查定位及手术引导。结果:18例颌面部非金属微小异物在超声定位引导下均顺利取出,未发生并发症。手术时间10～80min。7例从外伤伤口中取出,其余11例从手术切口中取出。结论:应用超声对颌面部非金属异物探查定位并引导颌面部手术摘除异物,简便易行,值得推广。     

探讨超声在摘除颌面部非金属异物的应用

目的　探讨超声在摘除颌面部非金属异物的应用。方法　用B型超声对22例颌面部非金属异物进行定性定位,后采取手术摘除。结果　22例患者中,20例在B超引导下成功摘除颌面部非金属异物,2例未能找到异物,后通过MRI检查后,手术取出。结论　超声对颌面部非金属异物定位准确,对临床治疗和制定手术方案具有重要的指导意义。     

光学导航技术在口腔颌面深部间隙异物取出术中的应用

目的:探讨光学导航技术应用于口腔颌面深部异物留置取出术的适应条件和临床价值。方法:对5例口腔颌面部外伤后异物留置于深部间隙的患者在导航辅助下行异物取出术,术前进行三维CT和数字减影血管造影检查,对异物进行空间定位,并将CT的Dicom数据导入STN导航系统中,用于术前手术规划和术中导航。术中观察导航系统的实时性和精确性,评价导航技术对口腔颌面部深部间隙异物取出的有效性。结果:在光学导航技术辅助下,5例留置的异物均能通过微创入路顺利定位和取出,术中未发现神经、血管损伤,术后亦未发现感染、呼吸困难等并发症。术后随访3～12个月,患者主诉症状均缓解,功能和面型取得了满意的效果。结论:光学导航技术在口腔颌面深部间隙异物取出术中的应用,尤其在解剖位置复杂和危险的区域,可以提高手术的精确性、微创性和安全性。     

增强现实联合导板治疗颌面部多发异物1例报告

随着社会经济的发展,颌面部创伤的致伤因素越来越多,并伴随着创伤,异物残留的情况也常有发生,除了可能损伤重要解剖结构以外,残留的异物还可能会造成感染、疼痛等二次损伤[1-3]。对于颌面外科医生来说,要在尽可能保证颌面部美观的前提下完成异物取出手术也是一个挑战,因此颌面部异物的诊疗一直是口腔颌面外科领域中的难题。     

Removal of a large number of foreign bodies in the maxillofacial region with navigation system

The removal of a large number of foreign bodies in the maxillofacial region can be complicated and challenging. In this case report, a specific strategy for removal of multiple foreign bodies in the maxillofacial region is presented. A girl diagnosed with 24 foreign bodies in her left lower face and neck underwent the surgery using a computer‐assisted navigation system. A specific strategy was used in this case, which included from one sub‐region to the next and from the easiest to the most difficult. This strategy is recommended for the removal of a large number of foreign bodies in the maxillofacial region with a navigation system.     

颌面深部异物存留的诊断及治疗

目的 研究颌面深部异物存储的诊断及治疗。方法 对28例颌面深部异物存留的病例，从病因，病史，体检，影像学检查进行分析，确定异物存留的诊断；同时从异物的取出，清除病灶，组织修复等方面观察治疗效果。结果 28例中，24例在手术前有明确的诊断；26例进行了异物取出术，清除病灶，修复组织损伤，抗感染及康复治疗。全部病例经6个月以上随访，未发现因异物存留，损伤引起的严重并发症。结论 颌面深部异物存留的诊断应涵盖病因，病史，体检，及影像学诊断内容。对于颌面深部的伤害性异物存留应采取积极的治疗策略，包括取出异物，清除病灶，修复损伤，康复治疗等。多学科协作及微创外科是该类疾病诊断和治疗的发展方向。     

Image-guided removal of foreign bodies

Foreign bodies are common in the head and face. We investigated the use of image-guided navigation systems for the removal of foreign bodies in 10 patients between 1998 and 2004. In all cases foreign bodies were retrieved. There were no major complications. Image-guided removal of foreign bodies is safe and valuable.     

Diagnostic and treatment methods in patients with acute perforations and foreign bodies of the maxillary sinuses]

Sixty-nine patients with acute perforations of and foreign bodies in the maxillary sinuses were treated with the use of new methods for the diagnosis and treatment, suggested by the author. Good late results (in 3 months to 8 years) were achieved in 48 patients.     

Management of inhaled and swallowed foreign bodies

Although accidental inhalation or ingestion episodes are very rare, the consequences can be very serious for the patient, so it is important when the total number of courses of dental treatment performed each year are considered. This article discusses the causes, likely sequelae and management strategies adopted following such incidents.     

Implants in the treatment of the maxillofacial patient

Despite the apparent advantages provided by implants to the maxillofacial patient, complete documentation of these benefits is lacking in the literature. This review uses existing published material as a basis to discuss the efficacy of implant use in maxillofacial prosthetics and the biologic rationale of the procedures. The use of implants with bone-anchored hearing aids; in maxillofacial surgery; and in maxillary, mandibular, and facial defects is presented. Reliable and valid patient-based evidence of treatment success, as suggested by the NIH Consensus Conference of 1988, is needed.
