During the 1991-1992 war in Croatia, 7,043 wounded persons were treated at Dr Josip Bencević General Hospital in Slavonski Brod. Among them, 728 (580 soldiers and 148 civilians) had war injuries to the head and neck and were admitted to the Department of Otorhinolaryngology and Cervicofacial Surgery. There were 541 (74.3%) patients with head injuries, 117 (16.0%) with neck injuries, and 70 (9.6%) with a combination of head and neck injuries. The wounds were mostly inflicted by shell and bomb fragments (542 wounds, or 74.5%). War injuries of the facial bones were preliminarily or definitively treated. Preliminary treatment was used for the wounds with multifragmentary fractures and extensive soft-tissue defects. Definitive treatment was used in lesions of cervical structures. Immediate exploration of the neck was performed on 84 patients with penetrating neck wounds. Exploration was positive in 49 patients. Concerning long-term complications, two cases of partial paralysis of the cranial plexus and one case each of quadriplegia, hemiplegia, and glottic paralysis were recorded. To our knowledge, primary closure of war wounds to the head and neck (supported by antibiotic therapy) and reconstruction of extensive laryngotracheal injuries with the medial layer of the cervical deep fascia were used for the first time as war surgery procedures.

From July 1, 1991, until January 1, 1993, a total of 7,720 patients (soldiers and civilians) with war wounds were treated at Dr. Josip Bencević General Hospital in Slavonski Brod, Croatia. Treatment was provided for 7,043 patients, whereas 677 individuals (8.8%) killed in action (KIA) were examined at the Forensic Department. There were 1,456 patients (18.9%) with head and neck wounds: 1,176 soldiers and 280 civilians. The mortality rate was significantly greater in patients with head and neck wounds (N = 271, 40.0%) than in those with injuries to the thorax (N = 163, 24.1%) and abdomen (N = 62, 9.2%; p < 0.01 for both). During treatment, 188 patients (2.4%) died of wounds (DOW). The DOW mortality was 5.2% (61 of 1,185), 4.0% (41 of 1,026), and 2.9% (25 of 867) for wounds of the head and neck, thorax, and abdomen, respectively. There was no significant difference in the mortality rate between head and neck and thorax wounds: however, the former exceeded the mortality rate recorded for abdominal wounds (p < 0.05). No significant differences were observed between soldiers and civilians with head and neck injuries either in the KIA (205 of 1,176, 17.4% vs. 66 of 280, 23.5%, respectively) or the DOW group (51 of 971, 5.3% vs. 10 of 214, 4.7%, respectively. According to the mechanism of head and neck wounding, there were 1,046 explosive (71.9%), 226 gunshot (15.5%), and 184 other (12.6%) wounds. Lethal outcome was significantly more common in gushot than in explosive wounds (79 of 226, 35% vs. 243 of 1,046, 23.2%; p < 0.01). The proportion of head and neck injuries did not differ significantly from literature reports on recent conventional wars. The site of wounding, i.e., at the battlefield or elsewhere, had no effect on the prognosis of wounds to the head and neck. Gunshot head and neck injuries showed a significantly higher mortality rate.

From 1 September 1991 to 31 December 1992, a total of 7,043 wounded patients were treated in the War Hospital in Slavonski Brod. Seven hundred and twenty eight patients with head and neck injuries were treated in the Department of Otorhinolaryngology and Cervicofacial Surgery. Of this number, 187 had neck injuries. Ninety-two (49.2%) of them were treated in outpatient facilities and 95 (50.8%) as inpatients. Immediate exploration was done in 84 patients with penetrating neck injuries. Vital structures were involved in 49 patients: major blood vessels (40 cases), larynx (17 cases), pharynx (8 cases), trachea (5 cases), thyroid gland (3 cases) and esophagus (2 cases). Definitive treatment was given to all of these injuries. Primary wound closure was performed upon exploration in 74 patients who were treated within the first 6 h after trauma. Secondary wound closure was performed in 10 patients with neck exploration performed more than 6 h after injury, and in those with extensive defects of tissue requiring the use of larger local flaps or free flaps. The mortality among patients with neck injuries was 2.1%.

Surgical exploration and immediate reconstruction with the median layer of the deep cervical fascia (MLDCF) was performed in 8 of 22 patients with exogenous war injuries of larynx and cervical trachea. A surgical technique of reconstruction with the median layer of the deep cervical fascia is described. The 7 surviving patients had good respiration without signs of stenosis of the larynx and/or the trachea. Four had good and 3 satisfactory, phonation, and none had swallowing difficulties. Owing to the simplicity of the surgical approach, its size and biological properties, the median layer of deep cervical fascia proved itself to be a suitable material in the immediate reconstruction of exogenerous war injuries of the larynx and cervical trachea.

Thirty-six patients with acute laryngeal trauma are presented. Sixteen patients had peace-time and 20 had war injuries. Peace-time injuries were mostly due to car accidents, violence and suicide using a knife, whereas the war injuries were caused by shell and mine fragments.Nine patients were treated conservatively (eight peace-time and one war-time) and 27 by surgery (eight peace-time and 19 war-time).Surgical experience showed that acute laryngeal trauma must be treated within the first 24 hours after injury. Primary treatment must be a definite one. In that way complications and uncontrolled healing can be successfully avoided.
