RESUMEN
Maxillofacial neurosensory deficiencies may be caused by various surgical procedures such as tooth extraction, osteotomies, preprosthetic procedures, excision of tumors or cysts, surgery of the TMJ and surgical treatment of fractures and cleft lip/palate. These deficiencies may be intolerable for the patient, mainly because of the elective nature of the procedures such as osteotomies. In this study, a retrospective evaluation of incidence of neurosensory deficiencies (NSD) in 227 patients who underwent different kinds of surgeries in the maxillofacial region is presented. Clinical neurosensory testing such as two-point discrimination, static light touch, brush directional stroke, pin-prick, thermal discrimination and dental vitality tests were used for evaluation. All the patients were grouped according to the surgical procedures and all of them were evaluated at least one year post operation. It was concluded that osteotomies, especially sagittal split ramus osteotomies, have the highest incidence of postoperative NSD.

Intramuscular hemangioma is a distinctly rare neoplasm originating within normal muscle. In the head and neck region, it occurs most frequently in the masseter muscle. Diagnosis of intramuscular hemangioma is extremely difficult because it is not encountered frequently and is often confused with salivary gland stone, parotid neoplasm or other tumors. In this report, a second case of intramuscular hemangioma of the digastric muscle and the diagnosis of this type of tumor in the early stage and the importance of its treatment are described.

The purpose of the study is to clarify the maxillary growth effects following different types of palatal closure in complete clefts of the lip and palate from infancy to 10 years of age. Lip repair, carried out at 5 months in one stage, was accomplished by Tennison's procedure. These patients were then assigned randomly to each of the 4 experimental groups according to the types of clefts and of palatal closure. One group of 14 patients in unilateral cases (Unil-S) and another group of 8 patients in bilateral cases (Bil-S) received mucoperiosteal palatal push-back procedure in a single stage at 20 months. The third group of 16 patients in unilateral cases (Unil-T) and the fourth group of 7 patients in bilateral cases (Bil-T) received the two-stage palatal closure based on Perko technique in which primary veloplasty was accomplished at 20 months and hard palate closure at 5 year 10 months. Non-cleft subjects were served as Controls. A longitudinal maxillary growth was monitored by the measurements of maxillofacial cast models obtained from each of the subjects. The results showed that the growth in depth and height of the maxilla of the Unil-T showed catch-up growth after primary veloplasty and resulted in no significant differences compared to that of the Control in the later phases, however, the Unil-S did not. The maxillary growth inhibition in height was characteristic in both Bil-S and Bil-T after palatal closure. There were no differences between the Bil-S and Bil-T in any dimensions and observation phases. The results indicate that the employment of the two-stage palatal closure is more beneficial for the unilateral cases, however, careful consideration is needed in bilateral cases.

In this research, 483 cases of intra osseous cyst treated in the Maxillofacial Surgery department of A.U. Dental Faculty has been examined. Out of these cases 15 have been non-odontogenic jaw cysts with and without epithelium. In this group 5 were nasopalatinal, 2 were median mandibular, 2 were median palatinal, 1 was globulomaxillary, 4 were solitary and 1 was a bone cyst. Non odontogenic cases have been elevated according to the differing classifications.
