An Analysis of Head and Neck Surgical Workload During Recent Combat Operations From 2002 to 2016.

Introduction: In battle-injured U.S. service members, head and neck (H&N) injuries have been documented in 29% who were treated for wounds in deployed locations and 21% who were evacuated to a Role 4 MTF. The purpose of this study is to examine the H&N surgical workload at deployed U.S. military facilities in Iraq and Afghanistan in order to inform training, needed proficiency, and MTF manning.
Materials and Methods: A retrospective analysis of the DoD Trauma Registry was performed for all Role 2 and Role 3 MTFs, from January 2002 to May 2016; 385 ICD-9 CM procedure codes were identified as H&N surgical procedures and were stratified into eight categories. For the purposes of this analysis, H&N procedures included dental, ophthalmologic, airway, ear, face, mandible maxilla, neck, and oral injuries. Traumatic brain injuries and vascular injuries to the neck were excluded.
Results: A total of 15,620 H&N surgical procedures were identified at Role 2 and Role 3 MTFs. The majority of H&N surgical procedures (14,703, 94.14%) were reported at Role 3 facilities. Facial bone procedures were the most common subgroup across both roles of care (1,181, 75.03%). Tracheostomy accounted for 16.67% of all H&N surgical procedures followed by linear repair of laceration of eyelid or eyebrow (8.23%) and neck exploration (7.41%). H&N caseload was variable.
Conclusions: H&N procedures accounted for 8.25% of all surgical procedures performed at Role 2 and Role 3 MTFs; the majority of procedures were eye (40.54%) and airway (18.50%). These data can be used as planning tools to help determine the medical footprint and also to help inform training and sustainment requirements for deployed military general surgeons especially if future contingency operations are more constrained in terms of resources and personnel.
