Reconstruction of a face destroyed by an explosion.

We have followed up the course of the facial reconstruction in a 12 year old boy with totally destroyed middle and lower third of the face when the fuse for initial mine activation exploded in his mouth. The boy has undergone more than 20 operations within the 7-year period and his rehabilitation has not been completed, yet.

Bimaxillary osteotomies in correction of dentofacial deformities.

In 342 patients with dentofacial deformities cephalometric analyses were preoperatively performed. A study of occlusion on cast models as the simulated new position of the facial soft tissues was done on the photographs. Surgical treatment using bimaxillary osteotomies for correction of dentofacial deformities was done in 38 patients: 31 with prognathism and maxillary hypoplasia, 5 with facial asymmetry and laterognathism and in 2 with otomandibular dysostosis.

How we have treated parotid gland tumors.

Since the Clinic was established in 1972 to the end of 1994 at the Clinic for Maxillofacial Surgery of the Military Medical Academy 782 patients with tumors of the parotid salivary glands of glandular origin were treated. This number included only patients with sufficient data for the relevant analysis. There were 659 (85.

Implants in management of gunshot injuries of teeth, facial bones and jaws.

The use of implants in management of gunshot injuries of teeth, face and jaws presents novelty that is manifested in primary surgical treatment, reduction and fixation of bone fragments and teeth, replacement of lost parts of bone tissues as well as preparation for definitive prosthetic management. At the Clinic for Maxillofacial Surgery of the MMA 173 implants of different types and purposes have been placed in the period 1991-1997, in rehabilitation of the patients injured during the civil war. Although this number of placed implants is significant, the conclusive estimate about benefit of using implants may be obtained only after a longer period of time.

Vascularized fibular graft in the reconstruction of posttraumatic mandibular defects.

The results of the use of the vascularized fibular graft for the reconstruction of posttraumatic defects of the mandible are presented. Different surgical procedures were applied in reconstruction of the mandibular defects in 120 wounded. In the last four years vascularized fibular graft was used in 11 mandibular reconstructions.

Facial nerve injuries and its treatment.

Twenty four patients with traumatic interruption of the conductivity of the facial nerve were treated in the period 1991-1996 at the Clinic for Maxillofacial Surgery. After topographic orientation about the site and level of the injury, the reconstruction of the nerve using nerve grafts was performed in all patients. The results were satisfactory.

Monocortical osteotransplant of the iliac bone in reconstruction of mandibular gunshot defects.

In the Clinic for Maxillofacial Surgery of Military Medical Academy, 134 injured with mandibular defects were treated, as well as a significantly larger number of injured from the territory of former Yugoslavia, with dominant injuries of the head and neck regions. Until June 1994, smaller defects were treated using bicortical osteotransplant of the iliac bone. Due to its only partial successfulness in reconstruction of mandibular defects, monocortical osteotransplant of the iliac bone was selected for reconstruction of the mandibular defects and the results were much better compared to the other free osteotransplants.

The treatment of traumatic facial bones and jaw fractures in the period 1972-1996.

During the last twenty-five years, in the period from January 1, 1972 to December 31, 1996, 1006 injured with facial and jaw fractures have been treated at the Clinic for Maxillofacial Surgery of the Military Medical Academy--91.05% of the injured were males and 67.98% belonged to the age group between 11 and 30.

Maxillofacial war injuries during the war in former Yugoslavia.

War wounds of the maxillofacial region occur in 5-17% of casualties. In the Clinic for Maxillofacial Surgery of the Military Medical Academy, during the war in former Yugoslavia, 482 casualties with dominant wounds in the maxillofacial region were treated. The outcome of the treatment depended on the quality and speed of the first aid and general medical aid, as well as on qualified specialist treatment.

Do prostaglandins E2, F2 alpha and D2 have a role in the development of idiopathic trigeminal neuralgia?

Idiopathic trigeminal neuralgia (ITN), resistant to the drug treatment was diagnosed in 20 patients using following parameters: clinical feature, usage of Bell-McGill questionnaire, as well as X-ray and neurophysiologic examinations. Peripheral neurectomy was performed in all of them as a palliative therapeutic procedure. In removed nerves of patients (n.

[Reconstruction of defects of the oral cavity with the myocutaneous sternocleidomastoid flap].

The sternocleidomastoid (SCM) muscle can be used for a muscular myocutaneous or osteomyocutaneous flap in the reconstruction of cancer and trauma related defects of the oral cavity. The SCM muscle has 3 principal arterial pedicles and a number of minor ones. The superior pedicle is a branch given off in about 70% of cases by the occipital artery, the middle is formed by a branch of the superior thyroid artery, and the inferior pedicle arises from the suprascapular or the transverse cervical artery.

[Blood autotransfusion in head and neck surgery].

Autotransfusion as a method of blood compensation after multilative surgical operation in cases of malignant neoplasm of the maxillofacial region, was introduced in our clinical practice in 1989, and up to now we have performed it in a group of 23 patients. It has been known that an autotransfusion depends on the patients' general health situation, hemoglobin level, hematocrit and iron concentration in serum. We exfused at least three days before operation 450 ml of blood from each patient.

[Motivation in patients for surgical treatment of prognathism using bimaxillary surgery].

A postoperative survey was conducted to evaluate the motivation of twenty three patients following surgical correction of mandibular prognathism. The operative technique of bimaxillary surgery was applied to all patients. The major reason for surgery was esthetics.

[Large dermoid cysts of the mouth floor].

Dermoid cysts of the mouth floor are very rare. The incidence of these cysts is up to 3.6% of all cysts in the oral cavity.

[Fractures of the zygomaxillary complex: indications for exploration and reconstruction of the orbital floor].

Within the period of 11 years 132 patients with fractures and dislocations of the zygomatic maxillary complex have been treated at the Clinic of Maxillofacial Surgery of the M.M.A.

[Emphysema of the neck caused by a blast injury of the anterior oral cavity].

Parapharyngeal emphysema after blast injury of the oral cavity is very rare. It occurs as a consequence of sudden increase in the air pressure in the oropharynx which lacerates the buccogingival mucosa and enables entering of the air into the neck spaces. A possible mechanism of development and the way of penetration of the air into the parapharynx are explained.

Evaluation of ultrasound in the diagnosis of pathologic processes in the parotid gland.

The values of ultrasound in differentiation of pathologic processes in the parotid gland were studied in 61 patients. The ultrasound findings were compared with operative and histologic findings. In 28 patients with chronic inflammatory processes, the ultrasound findings were in complete correlation with the histologic findings, showing enlarged parotid glands, homogenous glandular epithelium, and small, multiple cysts.
