Temerek, A. T., S. Ali, and M. F. Shehab, "Computer guided resection and reconstruction of intra-osseous zygomatic hemangioma: Case report and systematic review of literature.", International journal of surgery case reports, vol. 66, pp. 240-256, 2020. Abstract

OBJECTIVES: to systemically integrate the available data on various published treatment strategies for intraosseous hemangioma of the zygoma in an updated comprehensive systematic review, and to present a new case of treated resection and immediate reconstruction using computer guided patient specific composite graft.

CASE PRESENTATION: A 29 years old female patient with intraosseos zygomatic hemangioma treated using computer guided resection and immediate reconstruction. The resection was performed using a resection template constructed based on preoperative 3D planning. The reconstruction was performed using ramus bone graft and titanium mesh. The patient was followed up for 3 years with no complications.

METHODS: An electronic search was performed on 3 data bases; additional hand search of bibliographies of selected articles was performed. Eligibility criteria include human studies presenting intraosseous zygomatico-orbital hemangioma with clearly reported therapeutic strategies.

RESULTS: 53 articles with 73 cases were included. The lesion was highly prevalent in females compared to males (2.28:1). Fifth decade represents the highest prevalence with mean age of 44.1 ± 1.8 years. The main patient concern was swelling and facial deformity. Total tumor resection can assure no recurrence, while partial resection and curettage are associated with high recurrence rate.

Ahmed, M., and S. Ali, "Computer guided temporomandibular joint reconstruction of Kaban III hemifacial microsomia with anotia: A case report.", International journal of surgery case reports, vol. 57, pp. 52-56, 2019. Abstract

INTRODUCTION, Hemifacial microsomia is the second most common craniofacial congenital anomaly. It corresponds to a group of malformations ranging from minimal facial asymmetry to sever form affecting mandible, soft tissues, orbit, ear, and cranial nerves. PRESENTATION OF CASE, We present a case of 6 years old patient with Kaban class III hemifacial microsomia with anotia. Temporomandibular joint was reconstructed by costochondral graft using computer guided surgery (simulation and rapid prototyping). A computer guided soft tissue guide, mandibular, and maxillomandibular/zygomatic models were constructed using rapid prototyping technology. The customized computer guided soft tissue guide was used to localize the proper position of skin incision, the mandibular model was used for preoperative reconstruction plate bending, and the maxillomandibular/zygomatic model was used to estimate the rib graft length and position. Postoperative assessment showed proper positioning of the graft, with no complications or facial nerve affection. DISCUSSION, In this report, we introduce a new computer guided technique to estimate and identify the proper position of the temporomandibular joint graft based on patient CT. This technique eliminated the need of extended incisions with excessive dissection and provided a more accessible field for rib graft fixation, facilitating the surgical procedures. CONCLUSION, The use of computer guided surgery (simulation and rapid prototyping) for temporomandibular joint reconstruction in Kaban III hemifacial microsomia with anotia facilitates the surgical procedure, minimizes procedure time, increases precision, and reduces possible complications.

Elbehairy, and M. mounir, "Computer-Guided Arthrocentesis Using Patient-Specific Guides: A Novel Protocol for Treatment of Internal Derangement of the Temporomandibular Joint.", Journal of oral and maxillofacial surgery : official journal of the American Association of Oral and Maxillofacial Surgeons, 2019. Abstract

PURPOSE: The aim of the present study was to evaluate the accuracy of 3-dimensionally (3D) printed patient-specific guides (PSGs) to direct the passage of inlet and outlet needles into the superior joint spaces of the temporomandibular joint (TMJ) in preparation for arthrocentesis.

PATIENTS AND METHODS: The present study included 10 patients with 14 TMJs with anterior disc displacement with reduction. A 3D PSG was designed for each patient to lead the inlet and outlet needles into the superior joint space of the TMJ. The PSGs were implemented, and their accuracy for guiding the needles into the superior joint space was assessed.

RESULTS: Both arthroscopic verification and clinical evaluation revealed that direct access to all the predetermined anatomic locations inside the TMJs had been obtained, except for 1 case, during which the patient had failed to maintain the maximum mouth opening during computed tomography scanning.

CONCLUSIONS: The virtual computer-initiated PSGs were beneficial for directing the passage of the needles into the superior joint space.

Gouda, A., E. Helal, S. Ali, S. Bakry, and S. Yassin, "Maxillary sinus lift using osteoinductive simvastatin combined with β-TCP versus β-TCP - a comparative pilot study to evaluate simvastatin enhanced and accelerated bone formation.", Acta odontologica Scandinavica, vol. 76, issue 1, pp. 39-47, 2018. Abstract

PURPOSE: The aim of this study was to evaluate available bone quality and quantity after performing sinus augmentation using simvastatin/β-TCP combination versus β-TCP alone.

MATERIALS AND METHODS: This study included eight sinus lift procedures conducted on six patients. The sinuses were divided into two equal groups. The patients were recalled one, two weeks two, five, nine months post-operatively for post-operative evaluation. Radiographic evaluation involved cone beam computed tomography (CBCT) radiographs taken for every patient one week and nine months post-operatively to evaluate the changes in bone height, while histomorphometric evaluation involved transcortical bone biopsies taken after nine months during the second-stage surgery for implant placement.

RESULTS: The histomorphometric results showed that the amount of newly formed bone was higher in the simvastatin group when compared to the β-TCP group nine months after the surgery; the difference between the two groups was statistically significant. On the other hand, the radiographic evaluation showed that the rate of resorption of the simvastatin group was found to be higher than the control group; however, the difference between both groups was statistically insignificant.

CONCLUSION: These results showed that Simvastatin is safe to be used in sinus lift with promising osteoinductive capacity, yet further studies using larger sample size is needed.

Selim, K., S. Ali, and A. Reda, "Implant Supported Fixed Restorations versus Implant Supported Removable Overdentures: A Systematic Review.", Open access Macedonian journal of medical sciences, vol. 4, issue 4, pp. 726-732, 2016. Abstract

AIM: The aim of this study is to systematically evaluate and compare implant retained fixed restoration versus implant retained over denture.

MATERIAL AND METHODS: Search was made in 2 databases including PubMed and PubMed Central. Title and abstract were screened to select studies comparing implant retained fixed restorations versus implant retained removable overdentures. Articles which did not follow the inclusion criteria were excluded. Included papers were then read carefully for a second stage filter, this was followed by manual searching of bibliography of selected articles.

RESULTS: The search resulted in 5 included papers. One study evaluated the masticatory function, while the other 4 evaluated the patient satisfaction. Two of them used Visual Analogue Scale (VAS) as a measurement tool, while the other two used VAS and Categorical Scales (CAT). Stability, ability to chew, ability to clean, ability to speak and esthetics were the main outcomes of the 4 included papers.

CONCLUSION: Conflicting results was observed between the fixed and removable restorations.
