V. Saxena Graded Specialist Oral & Maxillofacial Surgery, 14 Corps Dental Unit, C/o 56 APO, India Introduction: Hyperbaric Oxygen (HBO) Therapy involves intermittent, usually daily inhalation of 100% humidified Oxygen under pressure greater than one atmospheric absolute (ATA). Each session lasts for 90 min and is termed a dive. Objective: The poster highlights application and effectiveness of HBO therapy in different Maxillofacial Surgery Cases. Method: A total of 05 Maxillofacial Surgery cases were subjected to HBO therapy at this high altitude Dental Centre at Leh, Ladakh where oxygen concentration is low. Results: The results have been encouraging and provide a definite hope for future. Conclusion: HBO therapy is advocated as an adjunct in Maxillofacial Surgery especially in cases of Osteoradionecrosis, refractory Osteomyelitis and Grafts. doi:10.1016/j.ijom.2007.09.066
To evaluate the efficacy of buccal mucosal graft in stricture urethra repair. Twenty patients with strictures urethra underwent buccal mucosal urethroplasty. For all of the 20 patients, a one-stage buccal mucosal onlay graft urethroplasty was performed. The buccal mucosa was harvested from the inner cheeks and inner part of the lips. All patients were followed up for eighteen months. In all the patients, buccal mucosal urethroplasty was successful. Two patients were noted with reduced mouth opening. The urethrogram was satisfactory in all the patients post operatively. Buccal mucosal graft is good, resilient, easy to harvest and has good vascularity. doi:10.1016/j.ijom.2007.09.068
Ultrasound study of patients who showed carotid artery calcification on panoramic dental radiograp M. Kumagai*, T. Yamagishi Department Oral and Maxillofacial Surgery, Department Internal Medicine, Tohoku Kosai Hospital, Sendai, Japan Objectives: To investigate atherosclerotic change of patients whose panoramic dental radiographs (PDRs) showed carotid artery calcification (CaAC). Methods: Intima-media thickness (IMT) of the carotid artery (CaA) was measured. Cases were divided into BL:CaA of those whose PDRs showed CaAC bilaterally (n = 36), UP: positive side of those whose PDRs showed CaAC unilaterally (n = 12) and UO: opposite side of UP (n = 12). Results: IMT in BL, UP, UO and control (n = 20) was 0.99, 0.75, 0.72 and 0.59 respectively. The control and BL had the lowest and highest values respectively. Conclusion: CaAC cases showed high IMT and Bilateral CaAC cases showed higher values than unilateral cases. doi:10.1016/j.ijom.2007.09.067
Objectives: To investigate the practice of thromboembolic prophylaxis in maxillofacial surgery. Design: Postal Questionnaire. Subjects: Institute based maxillofacial units as listed in the Indian Dental council’s directory. Main outcome measures: Factors considered in the decision to use thromboembolic prophylaxis and the methods of prophylaxis used. Results: Response rate 66%. Never used prophylaxis (48%respondents). Occasionally used (40%) Pharmacological methods were preferred. 48% of respondents never identified pregnancy, previous DVT (Deep vein thrombosis) or PE (Pulmonary Embolism), Malignancy, cardiovascular disease and oral contraceptives as risk factors. 36% felt that cost factor was the setback. 48% performed 5–10 major surgeries per month. doi:10.1016/j.ijom.2007.09.070

Self-tapping or drill free screws for orthodontic anchorage? N. Gupta*, S. M. Kotrashetti, R. K. Suryavanshi, S. D. Baliga, M. Umarani, T. Kale Department of Oral & Maxillofacial Surgery, KLES Institute of Dental Sciences, Belgaum, India
It is an established fact that unlike the rest of our body, only the brain enjoys the extensive multiplicity of vascular supply and anastamosis seen in our face. Branches from Internal & External Carotid artery systems, collateral non-valved venous drainage with emissary and anastomotic veins & venous plexuses, and a dense capillary bed capable of producing a blush or a blanch in an instant the above functions are important aspects of this phenomenon. This poster demonstrates how this proves to be a huge helping hand in the outcome of maxillo-facial treatment, though also leading to virtually uncontrollable blood-bath in trauma and surgery.
To compare stability and surrounding soft tissue reaction of self-tapping and drill-free screws placed in maxilla for orthodontic anchorage for retraction of anterior teeth. 10 patients requiring retraction of maxillary anteriors were selected. Titanium screws of both types (1.4 mm 6 mm) were placed on either side of maxilla for each patient under local anaesthesia. They were checked for stability and adjacent soft tissue reaction clinically and radiographically every month. The drill-free screws were found to be as stable as the self-tapping screws. Drill-free screws are easier and more compatible option for orthodontic anchorage, however, more studies are required to support these findings.

Poster R. Srirangam*, K. S. Gadre Department of OMFS, Bharati Vidyapeeth University, Dental College & Hospital, Pune 411 043, MS, India Trauma, infection, malignancy show no disparity among rich or poor, man or animal effecting everyone in a highly poised way. If nature shows no disparity, even man would not. Compassion and kindness have always been the symbol of humankind. If one thinks, animals suffering from these are left alone, to be abolished by these anathemas, to be fizzled before they sizzle, well think again at least not in Pune.

The prevalence four tongue lesions in 2–5-year-old childrens of north Tehra’s kindergartens Z. Tohidast Tehran University of Medical Sciences, Tehran The aim of this study was to investigate the prevalence of tongue lesions (Geographic tongue, fissured tongue, ankyloglossia, bifid tongue) in childrens of North Tehran’s kindergartens in relation to age, sex, systemic disease and allergies. A total of 583 kindergarten children aged 2–5 years were examined. Tongue lesions were found in 29.2% of all the children examined. Fissured tongue was the most common lesion (13.2%). Partial ankyloglossia was found in 7.9%, geographic tongue was found in 7.5% which was found more commonly in girls and bifid tongue was found in 0.5% of all children. doi:10.1016/j.ijom.2007.09.077
P77 Approach to the cervical spine – a technical note K. Prabhu*, D. Mehta, A. Shah, H. T. Davies Ipswich Hospital NHS Trust, United Kingdom Cervical disc disorders causing radiculopathy have been treated surgically from either an anterior or a posterior approach. Posterior laminectomy was used to successfully treat ruptured intervertebral discs. Since inception, the posterior approach for discogenic cervical radiculopathy has evolved. But still the decompression of the nerve root is indirect, leaving the compressive lesion untouched. The anterior approach was developed in the 1950s to achieve direct decompression of the nerve root. This report describes the surgical technique to accomplish direct nerve root decompression via the anterior
