Objective:Chronic periodontitis (CP) is a common inflammatory disease that causes destruction to the supporting tissues of the teeth. Many treatment modalities tried to stop the disease progression. Platelet-rich plasma (PRP) is one of the regenerative methods that used in adjunct to conventional periodontal treatment. The aim of this study was to evaluate the anti-inflammatory effect of PRP by monitoring the lymphocyte count before and after its application to the periodontal pocket.Materials and Methods:Twenty patients, with CP and a pocket depth equal to or deeper than 4 mm, subjected to scaling, root planing, and PRP injection into the pocket. The lymphocyte count measured before and after 1 month from PRP application. Clinical periodontal parameters were taken during two visits (1 month apart), with customized stent fabrication.Results:All clinical periodontal parameters showed a reduction in their value following 1 month of PRP application. There was a noticeable reduction in lymphocyte count from (mean 2.47 ± 0.91) to (mean 1.94 ± 0.77).Conclusion:In addition to its traditional uses, PRP has a great role in the periodontal treatment by its anti-inflammatory effect.

To reconstruct the orbital floor defects there are a lot of reconstruction materials, the surgeon must choose one of them. The authors share their experience with 10 patients suffering from orbital trauma causing orbital floor fracture; those fractures were reconstructed using titanium mesh. No complications were encountered postoperatively apart from 1 patient with ectropion. Titanium mesh is a perfect material for the reconstruction of the orbital fractures, eliminating the need for autogenous bone graft.

To preserve the continuity of the mandible after resection or traumatic bone loss, the defect is usually reconstructed with a bone graft fixed by a reconstruction plate. The fate of these plates is the objective of this study. Twenty-three patients (4 females and 19 males) required a reconstructive procedure to restore the discontinuity defect in the mandible by a mandibular reconstruction plate. Postoperative follow-up was performed to assess the outcomes of these plates. The mean age of the patients was 28.22 years. The most common cause of the discontinuity defect was bullet injury. The mean follow-up period was 3.65 years. The most common postoperative complication was the surgical site infection. The reconstruction plate of the mandible is associated with long-term success and body acceptance in the hands of an experienced surgeon.

Autogenous bone graft is the gold standard for maxillofacial reconstruction. Although there are many donor sites, the ilium is favored. Open iliac bone harvesting techniques can result in significant complications, which are to be reduced; a minimally invasive technique using trephine burs was used. The aim of the study was to evaluate the intra- and postoperative complications, the size of bone harvested, and the time of the procedure. Eighteen consecutive patients were conducted. The trephine bur makes holes of 10 mm diameter in the iliac crest from which a bone graft can be harvested. No major long-term morbidity was found; all patients were discharged on the first postoperative day. The trephine technique is generally a safe procedure, can provide enough corticocancellous bone for osseous defects in maxillofacial region up to 10 cc. In addition to that, the technique is easy to learn and allows early discharge of patients from the hospital.

The aim of the study was to evaluate the benefit of cone beam computed tomography (CBCT) and how to minimize injury to the posterior superior alveolar artery (PSAA) before sinus lift procedure. Cone beam computed tomography scans of 30 maxillary sinuses (15 patients) assessed to determine the location of PSAA presinus lift procedure. The data collected were used to extend the existed literature. The most common location of the PSAA was intraosseous (66.7%), the subantral distance mean was 5 ± 1 mm, and the mean distance of PSAA from the crest was 15 ± 1.6 mm. Cone beam computed tomography is valuable before the sinus lift procedure to exclude the presence of any lesion and to detect the location of the PSAA. The study recommends not to extend the upper border of the window beyond 16 mm from the residual crest during the lateral sinus approach.

The maxillofacial surgeon trained well to face the surgical challenges. In case of dealing with self-inflicted trauma, the surgeon must face the surgical as well as the psychological status of the patients. Five patients received in the emergency room suffering from maxillofacial trauma resulted from suicidal attempts. Unfortunately, 1 patient died, the other patients managed by providing surgical and psychological support. The cornerstone of managing such type of trauma needs appropriate communication between the family, surgical team, and the psychiatric.
