The maxillofacial injuries: A study

Objectives: The aim of this study was to evaluate the incidence and etiology of maxillofacial fractures and also to evaluate different treatment modalities. Study design: The sample consisted of 1,038 patients, with maxillofacial injuries treated at our center from June 2006 to June 2011. Cause, type, site of injury, gender, age and treatment given to them, all these parameter are evaluated. Conclusion: The results of this study exhibit that road traffic accidents is the main reason for maxilla facial injuries followed by fall from height. Maxillofacial injuries are more frequent in male than in female. The mandible was most frequently involved facial bone. The miniplate osteosynthesis was the most widespread of the fixation technique but conservative management of the fractured bone also has a significance importance in treatment modalities.

Pediatric facial injuries: It's management

Background: Facial injuries in children always present a challenge in respect of their diagnosis and management. Since these children are of a growing age every care should be taken so that later the overall growth pattern of the facial skeleton in these children is not jeopardized. Purpose: To access the most feasible method for the management of facial injuries in children without hampering the facial growth. Materials and Methods: Sixty child patients with facial trauma were selected randomly for this study. On the basis of examination and investigations a suitable management approach involving rest and observation, open or closed reduction and immobilization, trans-osseous (TO) wiring, mini bone plate fixation, splinting and replantation, elevation and fixation of zygoma, etc. were carried out. Results and Conclusion: In our study fall was the predominant cause for most of the facial injuries in children. There was a 1.09% incidence of facial injuries in children up to 16 years of age amongst the total patients. The age-wise distribution of the fracture amongst groups (I, II and III) was found to be 26.67%, 51.67% and 21.67% respectively. Male to female patient ratio was 3:1. The majority of the cases of facial injuries were seen in Group II patients (6-11 years) i.e. 51.67%. The mandibular fracture was found to be the most common fracture (0.60%) followed by dentoalveolar (0.27%), mandibular + midface (0.07) and midface (0.02%) fractures. Most of the mandibular fractures were found in the parasymphysis region. Simple fracture seems to be commonest in the mandible. Most of the mandibular and midface fractures in children were amenable to conservative therapies except a few which required surgical intervention.

Buccal fat pad versus sandwich graft for treatment of oroantral defects: A comparison.

Aim: To compare the efficacy of buccal fat pad (BFP) graft with sandwich graft (hydroxyapatite crystals embedded within collagen sheath) in closure of oroantral defects. Materials and Methods: A 2-year prospective study was conducted; 20 patients were included in the study were divided into two groups having 10 patients in each. Group I patients underwent surgical closure of oroantral fistula with sandwich graft and Group II patients with buccal pad of fat. Results: In Group I, the mean pain scores were 7.60 ± 0.84, 3.90 ± 1.10, 2.30 ± 1.16, 1.10 ± 0.99 and 0.40 ± 0.70 at immediate post-op., 1, 3, 6 and 12 week time intervals, respectively, whereas in Group II these were 7.30 ± 0.67, 3.50 ± 0.53, 1.70 ± 0.48, 1.00 ± 0.47 and 0.30 ± 0.48, respectively, at the corresponding time intervals. In Group I, swelling was seen to be present in 10 (100%), 7 (70%), 2 (20%) and nil (0%) patients at 1, 3, 6 and 12 weeks, respectively, whereas in Group II, it was seen to be present in 10 (100%), 10 (100%), 2 (20%) and nil (0%) patients at the corresponding time intervals. At 1 week, infection was seen to be present in 1 (10%) patient of Group I and 2 (20%) patients of Group II. At 3 and 6 weeks, infection was seen to be present in 1 (10%) patient of Group I and none of the patients of group II. No radiologic evidence of bone formation was seen in either group up to 1 week. At 3 week interval, there were 6 (60%) patients in Group I and nil (0%) in Group II showing bone formation, thus showing a statistically significant difference between the two groups. By 6 week time interval, radiologic evidence of bone formation was seen in 9 (90%) patients of Group I but in no patients of Group II, thereby showing a statistically very highly significant (P < 0.001) difference between the two groups. In Group I, in 1 (10%) patient, graft was rejected by first week; however, no further graft rejection took place. In Group II, no case of graft rejection was reported. Conclusions: The sandwich graft technique yielded a more promising closure of oroantral communication by provision of a more biologically apt base in terms of regeneration of lost bone structure at the floor of the maxillary sinus

Turmeric - A new treatment option for lichen planus: A pilot study

Turmeric is dried rhizome of the perennial herbs curcumalonga. It is called Haldi in Hindi, turmeric in English, ukon in Japanese. It has been used in Asian Medicine since the second millennium BC. It′s utility is referred to in the ancient Hindu script the Ayurveda. Pathogenesis of the OLP should be taken in consideration for the treatment point of view. The Cell mediated immunity to secondary antigenic change in oral mucous membrane is thought to play a major role in its pathogenesis modified keratocyte surface antigens are the primary target for cytotoxic cellular response. Curcumin also been shown to have immune modulatory effect involving activation of host macrophages and natural killer cells and modulation of lymphocytes mediated function.

Ameloblastoma of the anterior mandible.

Ameloblastoma or adamantinoma is the rarest of the three forms of tumor of the odontogenic type. They are benign, locally aggressive neoplasms arising from ameloblasts, which typically occur at the angle of the mandible, and are often associated with an un-erupted tooth and must, therefore, be differentiated from a dentigerous cyst which will be centered on the crown. When in the maxilla (less common), they are located in the premolar region, and can extend up in the maxillary sinus. Ameloblastoma is reported to constitute about 1-3% of tumors and cysts of the jaws. The tumor is by far more common in the mandible than in the maxilla and shows predilection for various parts of the mandible in different racial groups. The relative frequency of the mandible to maxilla is reported as varying from 80-20% to 99-1%. Here, we are representing a case of ameloblastoma of anterior mandible which was considered as a rare site of occurrence.

Osteogenic potential of cissus qudrangularis assessed with osteopontin expression

Purpose: Fracture healing involves complex processes of cell and tissue proliferation and differentiation. Many factors are involved, including growth factors, inflammatory cytokines, antioxidants, bone breakdown (osteoclast) and bone building (osteoblast) cells, hormones, amino acids, and uncounted nutrients. We studied the osteogenic potential of Cissus quadrangularis (CQ), a plant that has been customarily used in the Indian subcontinent to hasten the process of healing in bone fractures. Materials and Methods: Total of 60 patients (age, 20-35 years) of mandible fracture was divided in two groups. Patients of group 1 were given capsules of CQ and fracture healing was assessed with osteopontin expression during treatment. Group 2 was control group. Results: Clinical and radiological analysis in our study was suggestive of better healing of fractures in group 1. All the samples of group 1 examined for osteopontin expression using western blot analysis and flow cytometry showed significant levels of expression of osteopontin protein and CD4+ T cells expressing osteopontin, respectively. Conclusion: We conclude that CQ accelerates fracture healing and also causes early remodeling of fracture callus.

Congenital large maxillary teratoma

Teratoma of the maxilla is a rare entity. Congenital intraoral teratoma occurs in 1:4000 births. It is a benign tumor, although malignancy has been described in adults. A 10-year-old male child with this condition is described in this report. This case illustrates a huge mass on the right side of the maxilla. The mass was excised under general anesthesia. Histopathologically, it consisted of all three layers of embryonic elements with predominantly fibrous tissue. Postoperative result was uneventful and no recurrence was detected after 2 years.

Evaluation of implants placed immediately or delayed into extraction sites

AIMS AND OBJECTIVES To compare the success rate of implant placed immediately in extraction socket vs implant placed delayed in extraction socket. MATERIALS AND METHODS The study comprised of 8 patients (6 male and 2 female, aged from 14 to 58 year) for evaluation of implant placement immediately (i.e. Group - A) or delayed (i.e. Group - B) into extraction site, in which at 12 sites implants were placed. RESULTS The inclusion criteria for implantation was tooth/teeth with one or two degree mobility, root stumps, tooth with failure root canal treatment and extraction sockets. HI-TEC TRX-OP (Life Care) with abutment, non-submerged, tapered at apical 5 mm, sand-blasted & acid etched surfaced implants were used. These are one stage single implants made of commercially pure titanium. The length of implants used was 10 mm and 13 mm and diameter was 3.70 mm and 4.50 mm. The vertical bone dimension was determined by palpation and radiograph (intra-oral periapical, orthopantomograph and dentascan in some patients). Gingival condition, bone condition was examined clinically and radiographically. DISCUSSION Post-operative evaluation was done under clinical parameters (i.e. Pain (VAS), Swelling, Stability (By Glickman method), Gingival status, Probing depth (By Williams Periodontal probe), Patients compliance / satisfaction, Complications (If any) and Radiological parameters was (Intra-oral periapical radiograph, orthopantomograph, Dentascan). CONCLUSION Overall conclusion drawn from this study was that both the groups are showing similar results but Group-A is slightly better than Group-B.

Total avulsion of mandible in maxillofacial trauma

Mandibular trauma are a frequent injury of maxillofacial skeleton due to the mandibles prominence and relative lack of support. Maxillofacial injuries can be complex and can involve the skin and soft-tissues as well as bones resulting in fractures. Although, several cases of severe crush injury of the lower jaw have already been presented but total avulsion of mandible has rarely been reported. As with any facial fracture, consideration must be given for the need of emergency treatment to secure the airway or to obtain hemostasis if necessary before initiating definitive treatment. We presents a case report of completely avulsed mandible along with soft-tissue of midface region in pediatric patient following trauma, which was attempted to manage or repaired by successful microvascular surgical technique. Unfortunately, we lost the patient in next postoperative day due to cardiac complication. Avulsion of the lower jaw may further complicate the obstructive nature of the upper airway. Multi-specialty involvement in their management may be needed for management of such type of avulsion injury.

Huge Ossifying Fibroma of the Maxilla

Ossifying fibroma of bone is a central neoplasm of bone. It is more common in young adult with marked predilection for mandible. It is more common in females. Lesion is generally asymptomatic until growth produces a noticeable swelling and deformity. It presents an extremely variable roentographic appearance depending upon stage of development. This lesion is composed basically of many delicate interlacing collagen fibres, seldom arranged in discrete bundle, interspersed by large numbers of active, proliferating fibroblasts. The lesion should be excised conservatively. We present a case of huge ossifying fibroma arising from maxilla.
