Development and application of a rapid rehabilitation system for reconstruction of maxillofacial soft-tissue defects related to war and traumatic injuries.

ABSTRACT:

Background

The application of a maxillofacial prosthesis is an alternative to surgery in functional-aesthetic facial reconstruction. Computer aided design/computer aided manufacturing has opened up a new approach to the fabrication of maxillofacial prostheses. An intelligentized rapid simulative design and manufacturing system for prostheses was developed to facilitate the prosthesis fabrication procedure.

Methods

The rapid simulation design and rapid fabrication system for maxillofacial prostheses consists of three components: digital impression, intelligentized prosthesis design, and rapid manufacturing. The patients' maxillofacial digital impressions were taken with a structured-light 3D scanner; then, the 3D model of the prostheses and their negative molds could be designed with specific software; lastly, with resin molds fabricated by the rapid prototyping machine, the prostheses could be produced directly and quickly.

Results

Fifteen patients with maxillofacial defects received prosthesis rehabilitation provided by the established system. The total clinical time used for each patient was only 4 hours over 2 appointments on average. The contours of the prostheses coordinated properly with the appearance of the patients, and the uniform-thickness border sealed well to adjacent tissues. All of the patients were satisfied with their prostheses.

Conclusions

The rapid simulative rehabilitation system of maxillofacial defects is approaching completion. It could provide an advanced technological solution for the Army in cases of maxillofacial defect rehabilitation.

Project description:PurposeOne of the feared complications of war-related peripheral vascular injury is the development of delayed hemorrhage. This study describes our experience with an innovative protocol of surveillance diagnostic angiography to detect occult late vascular complications in an effort to prevent delayed hemorrhage.Materials and methodsThis retrospective cohort study was conducted at a single level one trauma center, reviewing patients with war-related peripheral vascular injuries caused by penetrating trauma from October 7th, 2023, to January 21st, 2024. Data collected included patient demographics, primary injury characteristics, associated complications, incidence of late vascular injuries (either symptomatic or occult), means of diagnosis, treatment strategies and outcomes.ResultsThe cohort included 41 patients with war-related peripheral vascular injuries affecting 51 limbs. All patients were male (100%) with a median age of 25 years, the majority being soldiers (85%). 24 occurrences of late vascular injuries were observed in 22 (43%) out of 51 limbs (100%). Half were symptomatic, with delayed hemorrhage occurring in 5 limbs in total (10%), and half were asymptomatic. A total of 17 surveillance diagnostic angiographies were performed with the sole indication of identifying occult late vascular injuries in asymptomatic patients, of which 4 (24%) were positive for findings. Five additional diagnostic angiographies were performed to assess late injuries discovered incidentally on imaging studies that were performed for other indications, and all were positive for late vascular injuries. Of all late vascular injuries, a total of 83% required subsequent treatment.ConclusionsLate vascular injuries are a potentially lethal complication of war-related peripheral vascular injury. Aggressive surveillance with diagnostic angiography prior to discharge from a high intensity care unit can detect asymptomatic late vascular injuries, the treatment of which may prevent life-threatening hemorrhage.
