Phenotypic heterogeneity has been a complex phenomenon lately, fetching attention in tumour pathology. Myofibroblastic differentiation is one such example and, besides, functional heterogeneity contributes to the biological behaviour of the tumours. Myofibroma is a distinctive neoplasm of myofibroblasts with a low incidence rate in the oral cavity.

Background: A routine mandibular fracture matures in about 12 weeks and hence hinders normal function significantly. Alternatives are being researched to hasten the healing and allow early function. This prospective study aimed to assess the osteogenic potential of the drug (CQ) on the mandibular fracture healing.

Morphological tampering of cellular architecture is a frequent phenomenon, leading to a spectrum of histological melange at light microscopic level. One such group of tumors which exhibit diagnostic and therapeutic dilemmas are the Clear cell tumors. Clear Cell Odontogenic Carcinoma (CCOC) is an infrequent tumor, which is aggressive by nature among the odontogenic tumors.

The high rate of mortality associated with cancer is due to its inherent nature to metastasize. Perineural invasion (PNI) is a relatively rare mode of metastasis, and a distinct pathologic entity that can be observed in the absence of lymphatic or vascular invasion which is still shrouded by mystery. PNI is a marker of poor prognosis.

Purpose: The aim of the study is to compare subciliary incision and 'sutureless' transconjunctival incision in the treatment of infraorbital rim fractures.

Materials And Method: In this prospective study, 40 patients with fractures of the infraorbital rim were selected and divided into 2 groups using random sampling technique. Group A patients were treated using 'sutureless' transconjunctival technique and group B patients were treated using subciliary approach.

An ideal emergence profile is vital for maintaining gingival health and developing esthetics. The ovate pontic which mimics a natural tooth gives the most appropriate emergence profile. For a successful ovate pontic restoration, an alveolar ridge of sufficient height and width is necessary to enhance the deficient ridge and to achieve an esthetic emergence profile.

Adenoid cystic carcinoma is a tumor of the exocrine glands originating primarily from the minor salivary glands. Though rare but there has been incidences of its spread into intracranial sites via different routes. We report of an intriguing case of remote metastasis of intracranial tumor in the pituitary diagnosed as pituitary adenoma which spread to the oral cavity as adenoid cystic carcinoma.

Fractures of hyoid bone resulting from trauma other than strangulation are very rare; hyoid bone fracture associated with panfacial trauma are even rarer. They occur more frequently in young individuals, and in men more than in women [1]. We report a comprehensive review of a case of hyoid bone fracture associated with head and neck trauma, induced by a direct blunt trauma onto the anterior neck.

Salivary gland tumors make up about 3% of all neoplasms of the head and neck. Salivary gland tumors vary widely in histopathological appearance, thus it prompted the development of a revised histopathological classification of tumours. Malignant tumors can arise in the major salivary glands or numerous minor salivary glands lining the mucosa of the upper aerodigestive tract.

Vestibuloplasty techniques are widely carried out to make the denture bearing area more suitable and adequate to receive the intended prosthesis. One of the major challenges after a vestibuloplasty procedure is to reduce post operative discomfort, scar contracture and subsequent loss in sulcular depth. A raw bony surface, as is obtained after Clark's vestibuloplasty is prone not only to infections and increased pain, but also to increased scarring during the healing phase.

Introduction: Trigeminal neuralgia (TN) often called as "Tic douloureux" is a syndrome characterized by paroxysmal facial pain, is one of the most painful and debilitating craniofacial pain disorders. The controversy regarding the etiology and treatment of TN still exists.

Objective: To evaluate the effectiveness of percutaneous radiofrequency rhizotomy (PRR) for TN, after failure of pharmacological management.

Introduction: Mandibular defects usually involve a combination of osseous and soft tissue deficiency and are among the most challenging problems in maxillofacial surgery, many options are available for mandibular reconstruction. One of the options discussed in literature recently being distraction osteogenesis.

Aim And Objective: The aims and objectives of the study were to evaluate clinically the technique of distraction osteogenesis to reconstruct mandibular defects, using indigenous transport distractors, and to evaluate the efficacy of Indigenous transport distraction osteogenesis device.

Lipomas represent about 1 to 5% of all neoplasms of the oral cavity. Although relatively common, few large series of intraoral lipomas and its variants are seen in the literature. Therefore, the author presents the four cases of intra-oral lipoma with one case of histological variant of lipoma, the fibrolipoma.

Background: Temporomandibular joint (TMJ) ankylosis or hypomobility involves fusion of the mandibular condyle to the base of the skull. It is a major clinical problem that affects many patients suffering from facial trauma, infection, or systemic disease. The treatment of TMJ ankylosis poses a significant challenge because of technical difficulties and a high incidence of recurrence.

Leiomyomas are benign tumors derived from smooth muscle that most commonly arise in the uterus, followed by the gastrointestinal tract and subcutaneous tissues. Deep presentations are typically asymptomatic unless they achieve substantial size, whereas subcutaneous presentations may be associated with considerable local tenderness and pain, in addition to alteration of the overlying skin color. The highest incidence occurs between 40 and 49 years of age in the orofacial region, the angiomyoma is the predominant subtype, representing nearly 75% of all reported cases [1].

Fractures of the facial skeleton in children are less frequent. This clinical retrospective study of 5 year was conducted on 95 patients aged less than 16 years who sustained maxillofacial injuries during the period 2003 to 2008. Age, sex, etiology incidence and type of fracture were studied.

Objectives: Owing to the aggressive nature of OKC's if one could stop or even reverse the growth of the cyst with a simple procedure like decompression, regardless of the histologic type, it would be an alternative to radical and disfiguring surgery.

Methods: Eight patients who were diagnosed with Odontogenic keratocyst of the mandible were chosen and the first stage of treatment being, insertion of the decompression stent into the most prominent or dependent part of the cystic cavity. Then based on assessment of regular second monthly OPG radiograph the second stage ie.

Children are uniquely susceptible to cranio facial trauma because of their greater cranial mass to body ratio. Below the age of 5, the incidence of pediatric facial fractures in relation to the total is very low ranging from 0.6-1.
