Eissa, M. A., R. M. Mounir, and M. Faramawey, EVALUATION OF SANDWICH OSTEOTOMY FOR VERTICAL AND TRANSVERSAL AUGMENTATION OF THE POSTERIOR MANDIBLE, , 2014. Abstract

This study aimed to assess the efficacy of sandwitch osteotomy technique in reaching the
dimensional requirements of preimplant bone augmentation in the case of the atrophic posterior
mandible. Sandwich osteotomy was performed on eight patients having atrophy in the posterior
mandible with an estimated bone height of at least 4 mm above mandibular canal and not more
than 10 mm in addition to a transverse width of at least 3 mm. Chin graft harvesting was done and
the corticocancellous block was fixed at the recipient site using miniplates and screws. The mean
vertical immediate bone gain was 3.19±1.03 mm while that recorded at 3 months postoperatively was
2.56±1.11 mm. The mean transversal immediate bone gain was 1.16±0.41 mm while that recorded
at 3 months postoperatively was 0.63±0.47 mm. The study concluded that sandwich technique of
ridge augmentation was found to be a reliable technique in increasing vertical dimension of alveolar
ridge but it has limited application in increasing transversal dimension of alveolar ridge.

Eissa, M. A., H. R. Hassanien, and D. A. Radwan, EVALUATION OF TEMPOROMANDIBULAR JOINT ARTHROCENTESIS WITH INTRAARTICULAR PIROXICAM INJECTION, , 2010. Abstract

This study aimed for evaluation of the clinical response to arthrocentesis with and without intraarticular piroxicam injection in relation to synovial level of TNF-α in patients of TMJ clased lock. Eighteen patients were refractory to conservative treatment and were divided into 2 equal groups. In the study group arthrocentesis was performed followed by intraarticular piroxicam injection. In the control group, arthrocentesis was performed alone. Synovial fluid samples were obtained immediately before arthrocentesis and then at one week postoperatively for biochemical evaluation of TNF-α. The patients were clinically evaluated preoperatively, 1week and 3months postoperatively.
In the current study, with the exception of significantly higher mean visual analogue scale reduction at the preoperative-one week period and the significantly higher mean MMO increase at the period one week-three month in group II, the evaluated parameters showed insignificant difference between groups throughout the study intervals.
