The study samples included 12 anatomical specimens taken from the fixed corpses of various gender and age. Pterygomandibular space topography was assessed by macro - and micropreparation methods. The landmarks for the universal way of mandibular anesthesia were defined associated with low risk of medial pterygoid muscle, lingual nerve, inferior alveolar neurovascular bundle damage. The study results allow increasing the efficiency and safety of anesthesia of the lower jaw teeth.

Most compound acetabular fractures involving both the anterior and posterior columns are caused by high-energy injuries. Patients with compound acetabular fractures are often in critical or poor condition and cannot tolerate major surgery. This study aims to investigate the effectiveness of an ilioischial plate in treating compound acetabular fractures. A consecutive series of 40 patients with complex acetabular fractures were surgically treated and retrospectively reviewed. A modified Stoppa approach in combination with an iliac fossa approach was used. In all of the cases, the anterior column was stabilized with reconstruction plates for the iliac wing and along the iliopectineal line to the pubis. The posterior column was fixed either with the newly developed ilioischial plate running from the ilium to the ischial ramus or with standard fixation techniques. These included either conventional posterior column screws or quadrilateral plate fixation. Patients were divided into an experimental group (ilioischial plate for posterior column fixation) and a control group (standard fixation techniques). In both groups, we found that 90% of all reductions were good to excellent. According to the modified Merle Aubigne and Postel scoring system, the percentage of good to excellent was 85% in the experimental group as compared to 80% in the control group. Compared with the control group, physical function (PF), role physical (RP) and social function (SF) were significantly better in the experimental group (P<0.05). Fracture healing was achieved in all patients. By using the modified Stoppa approach combined with the iliac fossa approach, the ilioischial plate can be directly fixed to the posterior column and the ilium to stabilize the posterior column in patients with complex acetabular fractures.
- Does the Winter or Pell and Gregory Classification System Indicate the Apical Position of Impacted Mandibular Third Molars? [Journal Article]
- JOJ Oral Maxillofac Surg 2019 Jun 19
- CONCLUSIONS: The possibility of the buccal position of the tooth and the chance of an intersection of the apex into the IAC was greater with teeth that were mesioangular and were Class III concerning the ascending ramus and level C in depth. These data should be considered during the preoperative assessment of third molars to reduce postoperative complications.

Hemimandibular hyperplasia was first described in 1836 by Adams as a disorder that causes condylar hyperplasia, deforming facial asymmetry and has an unknown etiology. The objective of this study was to report a patient with surgical correction through orthognathic surgery and high condilectomy for the treatment of hemimandibular hyperplasia. The patient complained of pain and cracking in the right temporomandibular joint region and was dissatisfied with the aesthetic appearance of the face. Virtual planning was done for bimaxillary orthognathic surgery and preparation of prototyped surgical guides. Stereolithographic models were used for the preparation of the acrylic guides of the osteotomies for the high condilectomy and the contour of the mandibular base. Orthognathic surgery resulted in the maxillary repositioning with correction of the inclination of the occlusal plane, reduction of the height of the ramus and right mandibular body and class I dental attachment. Mandibular contour osteotomy was performed with acrylic guide in the basilar. The condilectomy was performed by endaural access. In 2-year follow-up, there are no signs of recurrence.
- Evaluation of the Spatial Position and Correlation of Mandibular Ramus in Skeletal Class III Patients With Mandibular Asymmetry. [Journal Article]
- JCJ Craniofac Surg 2019; 30(5):e439-e442
- CONCLUSIONS: When evaluating mandibular asymmetry and making surgical plans, the position of mandibular ramus should be taken into consideration.
- Comparison of condylar morphology changes and position stability following unilateral and bilateral sagittal split mandibular ramus osteotomy in patients with mandibular prognathism. [Journal Article]
- HFHead Face Med 2019 Jul 11; 15(1):18
- CONCLUSIONS: Both BSSRO and USSRO exhibit favorable postoperative stability in the correction of mandibular prognathism. After USSRO surgery, condylar surface changes occurred at the deviated side of the TMJ, and the dental midline deviation was closely related to the changes of condylar surface morphology. USSRO represents a stable alternative for minor asymmetric mandibular prognathism correction with the advantages of reduced operating time and surgical trauma.

Ameloblastic fibroma is a rare, slow-growing odontogenic mixed tumor with neoplastic epithelial and ectomesenchymal tissue, which does not show inductive changes to form enamel and dentin. It is frequently found in the first two decades of life. It is often confused with ameloblastoma and dentigerous cyst due to the presence of an impacted tooth and can be distinguished histologically. Ameloblastic fibroma can be differentiated from ameloblastoma by the presence of myxoid appearance of connective tissue. A case of an 11-year-old female with a slow-growing swelling on the left side of mandible in the molar ramus region has been presented which was diagnosed as ameloblastic fibroma postenucleation.

The present study reported the clinical outcomes of 35 patients with mandibular odontogenic keratocysts (OKCs) following treatment by radical resection and immediate defect reconstruction. Amongst 565 patients with OKCs that were treated between April 2003 and May 2015, 35 patients underwent segmental or marginal mandibulectomy. The use of radical resection was based on clinical and/or radiographic evidence of size, cortical perforation and subsequent soft tissue involvement, and on the history of previous recurrence of the same lesion. Recurrence, justifications of the main major factor for resection, and functional and cosmetic results of the patients following mandibular reconstruction were systematically evaluated. There were 26 OKCs in the mandibular molar-ramus region, eight in the mandibular anterior-premolar region and one in the mandibular molar-ramus and anterior-molar regions. Among the 35 patients, 20 had primary OKCs and 15 had recurrent OKCs. A total of 31 patients underwent segmental mandibulectomy, of which 28 were immediately reconstructed with a vascularized flap, whereas four patients underwent marginal mandibulectomy. The functional and cosmetic outcomes of patients were evaluated as satisfactory. The length of the follow-up period ranged from 2 to 17 years following operation (average, 5.82 years). Recurrence was identified in one patient who had been treated with marginal mandibulectomy. In conclusion, the findings from the present study suggested that radical resection may be recommended for patients with OKCs and locally aggressive features. Immediate mandibular reconstruction with a vascularized flap may be a crucial part of this aggressive treatment method that may reduce OKCs-associated morbidity.
