Abstract

Auricular reconstruction represents a meticulous reconstructive and aesthetic problem to theplastic surgeon. One of the greatest challenges in facial plastic surgery is total earreconstruction. The ability to reconstruct a fully satisfactory complete external ear has forcenturies been an elusive goal. The most promising field of advances with the hope ofeventually clinical utility lies in the realm of bioengineering with cultured cartilage.To date, no perfect material has been found to substitute for the sharply elastic cartilagenormally present in ear, the matter of total auricular reconstruction remain very complex,Prosthetic restoration is not favored by most but does remain available option for manypatients. Tissue engineers have waited to create a precise three dimensional auricularreconstruction neocartilage.Ten patients were operated upon for auricular reconstruction in Basrah Alsader TeachingHospital. The operation had 2 stages: First stage, creation and implantation of frameworkcartilage graft, which harvested from the 6th ,7th & 8th ribs. The second stage, was detachment ofthe constructed auricles ear lobe transposition and post auricular sulcus was defined byseparating the constructed auricle from the head covering the under surface with a thick splitthickness skin graft.The success rate was 90% with good and satisfactory result except in one case; there wasinfection with loss of the cartilage.

Abstract

In this paper, the reconstruction of an object (faces) in the form of a 3D model (3D point) from unconstrained images (different in pose) has been studied. Beside with the 3D reconstruction of the object (faces), the paper also aims at estimating camera poses from a sequence of views. The structure from motion (SFM) method has been used in 3D reconstruction techniques, The SFM technique has 5 fundamental steps, namely Feature detection and extraction, feature matching, motion estimation (Computation of the fundamental matrix), triangulation and bundle adjustment. The results of the proposed algorithm show it's very encouraging as far as execution time and quality of reconstruction

Abstract

Wavelet Transform in 1992 recently as a combination with elman recurrent neural network. These are found very useful for time scale representation and widely used in signal processing and computer vision. In this research proposed an algorithm to reconstruct image that had lost some of its parts or uncompleted and some of wavelet transform properties in analysis to represent things. The algorithm depend on 8-level of wavelet decomposition with feature extraction and elman recurrent neural network for uncompleted image in small and big losing blocks. The reconstruction done in 100% accurate with the existing of original image even if the losing is 75% from the original image.

Abstract

Introduction: Different surgical techniques used for closure of various oral defects. While each one of thesetechniques has its limitation; the buccal pad of fat used in last quarter of last century as pedicle or free graft inreconstruction of small to medium, congenital and acquired defects showed good potentials for success. Thepresent study used the BPF as pedicled flap to reconstruct intra oral defects. The study aimed to evaluate of thesuccess of buccal pad of fat pedicled flap in the reconstruction of intra oral defects. Outlining its indications,limitations and complications.Materials and Methods: The study included 19 patients (17 males and 2 females) with age range between (1- 70years), all patients were treated with pedicled BPF for intra oral defects (8 pts. with oro-antral communications, 5pts.with maxillary alveolar bone defects, 4 pts. with cleft palate, and 2 pts. with carcinoma of buccal mucosa), undergeneral or local anesthesia. Follow-up period was for 3 months post-operatively,Results:The results showed that 94.7% of patients had complete epithelization of flap and complete closure of thedefect within 4-6 weeks. Only 1 pt. 5.3% had total flap loss with very small size of the BPF. In postoperative period, 5.3%of pts. complained from pain, trismus, vestibular obliteration, partial flap loss, all disappeared gradually within 1month from the reconstruction.Conclusion:The BPF is reliable, easy, safe method to reconstruct small and medium size intra oral defects of maximumsize 5x4x3 cm, in maxilla from upper canine region to the soft palate, and in buccal mucosa from retro molar area tothe commissure of the mouth

Abstract

ABSTRACT:BACKGROUND:Skin loss of perinioscrotal region may result from severe infections, avulsion trauma or crush wounds. Replacement with sensible durable cover is mandatory for functional, cosmetic and psychological reasons. Wide range of flap techniques have been reported for these purposes.OBJECTIVE:To evaluate the use of superomedial fasciocutaneous thigh flap for replacement of scrotal and penile skin loss.PATIENTS AND METHOD:7 male patients aged between 25 and 69 years(mean=53.4) were included in this study. All of them presented, in the period between2007-2010,with scrotal and penile skin loss. Four of them were with Fournier's gangrene, one was with history of agriculture accident, one with crush wound, and the last one was with penile skin loss after improper use of penile clamp. Superomedial fasciocutaneous thigh flaps were planned, elevated at subfascial plane, then transferred to close the wounds. Bilateral flaps were used in five patients for total scrotal reconstruction. All patients were followed for 3-13 months.RESULTS:12 flaps were used for the 7 patients with complete survival. These provided nice durable covers of the testes with good sensation. The flaps were moderately bulky in one patient. Other complications included serous fluid collection in one patient, wound dehiscence in two patients, paresthesia of the anterior aspect of thigh in 2 patient, and mild leg edema in one patient. All complications were transient and responded well to conservative treatment.CONCLUSION:Superomedial fasciocutaneous thigh flap is a good choice for scrotal and penile reconstruction that could provide a sensible, durable cover that fulfills patient satisfaction.

Abstract

In this research, an experimental test has been conducted to study the pumpingcharacteristics of a vapor-bubble pump based on water properties. It also includes atrial based on the obtained experimental data to correct and reconstruct thepreviously developed theoretical mathematical model of this bubble pump. Themathematical model that was developed for general fluid properties can be usedafter modification to represent the actual behavior of the water vapor-bubble pump.Most of the bubble pump configuration parameters which may affect itsperformance are experimentally investigated. Three different inner tube diameters(8, 10, 12 mm) with five submergence ratios (0.2, 0.3, 0.4, 0.5, and 0.6) are tested.The results showed that the bubble pump capacity increases with the thermalenergy processed and continue to increase up to a maximum value then begin todecline. Each tube diameter has its own maximum discharge; the bigger tubediameter gives higher maximum discharge which is in turn increases with theincreasing of submergence ratio. The experimental results of the pumping capacityare compared with those obtained from the mathematical model .Then themathematical model is reconstructed by adding a correcting factor (K). This factoris necessary to account for the discrepancies that observed between theexperimental and the theoretical results. The margin of error between the results ofthe resulting corrected mathematical model and the results of the practical test wasacceptable and it can use this new model to analyze the performance of the bubblepump.

Abstract

Background: In Maxillofacial surgeries, iliac bone graft has traditionally been harvested to provide osteoconductive,osteoinductive and osteogenic components to initiate bony formation. There are multiple types of procedures forharvesting iliac bone graft, either by surgical exposure procedure for procurement bone graft bicortical, unicortical,tricortical or by using Fritsch bone harvesting (trephine) system or by Spine-Tech grinding harvester technique. Thisstudy compares procedures for harvesting iliac bone graft by using sub-crestal window technique procedure andtrap-door iliac crest bone graft procedure for different purposes like alveolar cleft, bone resection due to tumor,reconstruction of avulsed facial bone due to trauma by bullet injury or RTA, confirming that donor site morbidity ofthe sub-crestal window technique is more significant than trap-door technique.Patients and methods: In this study (40 patients / 22♂:18♀) underwent harvesting of iliac bone graft with age range(3.5-65 years) in Al-Kadhmyea Teaching Hospital (2009-2012) for different purposes like alveolar cleft, reconstructionof mandible after tumor resection and reconstruction of maxillofacial defects due to massive blast or bullet injury.Results and Conclusions: The results indicate that major complications from ICBG harvest are uncommon, but minorcomplications are common. The findings suggest that donor site morbidity of the sub-crestal window technique issignificantly less than trapdoor technique. Making the sub-crestal window technique is the method of choice forharvesting large amounts of bone graft

Abstract

بعد مرور أربعه وعشرين عاما (1980-2003) من الحروب والحصار الاقتصادي تحول العراق من دولة تتمتع بالعديد من مقومات القوة الاقتصادية- من موارد طبيعية هائلة وامكانات بشرية مؤهلة- إلى وضع صعب يرثى له على المستويات السياسية والاقتصادية والاجتماعية والبيئية كافة إذ دمرت البنية الأساسية وتدهور النشاط الاقتصادي ووصلت الأوضاع الاجتماعية إلى درجة شديدة من التردي في ظل ارتفاع البطالة والفقر وبلوغها معدلات خطيرة.ووسط هذه الأوضاع فإنَّ الحرب الأخيرة على العراق قد رسخت من وضعيته المتأزمة اقتصاديا واجتماعيا ونقلتها من السيئ إلى الأسوأ بسبب ما احدثته آليات الحرب من تدمير لما تبقى من المرافق العامة وتوقف النشاطات الحياتية برمتها.

Abstract

ABSTRACT:BACKGROUND: Anterior cruciate ligament reconstruction (ACLR) is one of the most commonly performed orthopedic procedures. Technical factors especially correct tunnel placement play major role in its success. However its failure rate is still high (10%), and impingement of the graft on the posterior cruciate ligament (PCL) and the medial wall of the lateral femoral condyle is an important cause of failure. Wallplasty is a technique used to prevent graft impingement, but there is no consensus on its routine use.OBJECTIVE:Is to compare between the postoperative knee functional outcome and stability of arthroscopic ACLR performed with wallplasty versus those performed without wallplasty.PATIENTS AND METHODS: A prospective experimental non randomized study was performed on 32 patients (30 males and 2 females) who necessitated arthroscopic ACLR. The patients were divided into 2 groups, in group A (made of 16 patients) the reconstructions were done without wallplasty and in group B (made of 16 patients) were done with wallplasty. Three months postoperatively the two groups were compared in regard to Lasholm score changes (preoperative and postoperative), Lachman test, and Pivot shift test results.RESULTS: There was better improvement in Lasholm score in group B than in group A, and the difference was statistically significant (p value =0.036). Knee stability tests were better in group B than in group A, but the differences were statistically not significant.CONCLUSION: Wallplasty has statistically better functional outcome than non wallplasty in ACLR and it is recommended to be done routinely in all cases of ACLR.
