هو تقييم النتائج السمعية والكلامية لعمليات زرع الحلزون في تشوه الجوف الواحد إِذ إن الإذن الداخلية توقفت عن التطور في الأسبوع الثالث من الحياة الجنينية. و كان في الماضي يعد وجود أي تشوه في الحلزون هو مضاد استطباب للعملية، و لكن بدأت تجارب في بعض المراكز و حصل بعض النجاح مما شجع على متابعة العمل في بقية المراكز و شجعني على إجراء هذه العمليات الثلاث.
to evaluate the results of cochlear implant operations performed on patients with common cavity anomalies in the inner ear; whereas, the ear stopped developing at the end of the third week. In the past, the presence of any anomaly in the cochlea was considered a counter-indication for surgery but experimentation has been carried out worldwide and there were some major breakthroughs, which encouraged other centers worldwide to carry out this surgery and I was encouraged myself to perform 3 surgeries.

Background& Objective: The acetabular bone deficiency secondary to acetabular fractures presents a
complex clinical problem and a big challenge to the orthopedic surgeons due to the technical difficulties
related to this deficiency, considering tha
t significant number of patients treated either surgically or
without surgery will require T.H.A in the future.
The purpose of our study was to determine the outcome of T.H.R performed in patients with a history of
acetabular fracture.
Materials & Methods: We performed T.H.R in 21 patients with previous acetabular fractures in Al-Assad
Hospital between2004-2009prespectively, these cases were divided into 3 groups:
-first group formed of 7 patients were treated conservatively. Second group formed of 9 patients did an
open reduction and internal fixation by screws and plates.
-Third group formed of 5 elderly patients with fresh acetabular fractures and were treated primarily by a
total prosthesis with use a reinforcement Muller ring .
For the clinical evaluation of our cases we used the modified Harris Hip Score Scale and for the
radiological evaluation we used the Delee and Charnley scale system .
Results: Our overage Harris Hip Score was 83.(80 for the first group, 86 for the second group, and 83 for
the third group).
-No complications were encountered intraoperative, in the early postoperative period one case developed
superficial wound infection and treated by repeated dressing and antibiotic, there was one case of D.V.T
on the 4th day treated by rest and anticoagulant, and one case developed loosening of acetabular
component 8 months after T.H.A and underwent to revision.
Conclusion: T.H.R in acetabular fractures despite the difficulties faced during the procedure is a safe and
effective way to salvage the hip when secondary osteoarthritis develops, open reduction and internal
fixation of acetabular fractures may have benefits even if it fails to prevent posttraumatic arthritis
.Furthermore the clinical results of T.H.R after surgical treatment of acetabular fractures are better than
it after conservative treatment of these fractures.
Reinforcement ring is an ideal solution when the decision of T.H.R is taken as a primary treatment of
acetabular fractures depending on the indications described by Joly.
coxathrosis secondary to the untreated developmental dysplasia of the hip is still
encountered against all the screening and early treatment methods.T.H.A in DDH presents challenging
surgical problems to the orthopedic surgeons due to the associate
d anatomical changes and the technical
difficulties related to the bone deficiency in the acetabulum.
The purpose of the study is to examine the clinical and technical problems associated with reconstruction
of the hip in patients with congenital dysplasia and to offer recommendations for their Solutions.
Objectives: The purpose of this study was to evaluate the influence of
glass fibers in strength acrylic resin fracture around a overdenture
abutment.
A model was designed to simulate the
clinical situation of an implant overdenture abutment (50-1
2-1.5mm).
thirty specimens were divided divided into 3 groups, ( 10 specimens
without glass fibers , 10 specimens with one glass fibers, 10
specimens with two glass fibers). All specimens were submitted to a
3-point bending test
Mandible articulates with the cranium via the TMJ. All the components of the TMJ,
including the TMJ disc, seem to be associated with altered characteristics of the
craniofacial complex and its growth. However, the exact role of the TMJ disc thickne
ss
during the process of the facial growth is not clear yet.
Aim: The aim of this study is to investigate the association between the TMJ disc
thickness and the facial growth determined according to Jarabak in adult male subjects
with no clinical or MRI symptoms of Temporomandibular Joint Disorders.
Existing bone loss still remains an important challenge when implant placement
is required to rehabilitate the compromised site. A new way to place dental implants in cases of alveolar
atrophy, described in some articles, is the ridge-splitting tec
hnique, which allows the ridge to be widened
by a less invasive procedure than the traditional grafting approaches. The aim of this study is to evaluate
the efficiency of this technique in bone augmentation, evaluate the relationship between peri-implant
alveolar bone loss after Use of the Bone Splitting Technique, and to study the alveolar ridge width before
and after split.
