    Author: Shuker ST.
    Journal: J Oral Maxillofac Surg; 2010 Jan; 68(1):93-100. PubMed ID: 20006161.
    Abstract:
    PURPOSE: Distinctive mechanisms of primary blast effects have produced a transitional era of facial trauma. Implosion mechanism damage is one of these. Implosion mechanism damage results in injury limited to the gas-containing structures of the auditory canal, paranasal sinuses, gastrointestinal tract, and lungs. Worldwide, the victims of explosive detonations have increased and advanced dramatically. The outcome is greater mortality and morbidity and new types of injuries, especially in the maxillofacial region. Thus, the knowledge of, and experience with, their management should be shared globally by colleagues through publications. MATERIALS AND METHODS: The implosion and mini re-explosion of compressed air sinuses leads to skeletal crush injury to the nasal-orbital-ethmoidal, maxillary sinuses, and nasal bones. A variety of surgical approaches were used successfully under conditions of war. The assessment of the associated injuries to the lung and/or brain is the initial priority to any life-threatening blast injury. This article describes the biophysical results of blast injuries to the middle third facial skeleton and associated injuries and details the management and protection of crushed air containing paranasal spaces. RESULTS: Easy, simple, and fast treatment and management were used successfully on the pulverized, fragmented skeletal architecture of the facial middle part without increasing morbidity and with the avoidance of unnecessary surgical trauma. CONCLUSIONS: Injuries in one of the most difficult esthetic, physiologic, and anatomic regions of the body is best treated with an understanding of the biophysical effects of the implosion mechanism on air-containing spaces in the maxillofacial region. The introduction of new methods for the management of severe destruction of hard and soft tissue will decrease the incidence of complications and the operative time.
