This very rarely reported syndrome affects various ethnic groups and can present with manifestations other than those usually reported. Pseudoanodontia is a rare clinical and radiologic manifestation that is always associated with GAPO syndrome. Osteomyelitis of the jaws is a less common disease that is usually attributed to odontogenic causes. This case report describes osteomyelitis of the mandible in a patient with GAPO syndrome. Further, an additional 3 cases of GAPO in the patient's family, with special emphasis on oral mucosal changes and pseudoanodontia, are discussed.

It commonly affects, adults between the third and fourth decade of life and often shows variations in clinical, radiographic, and histopathologic features, hence require different treatment options. Purpose: This paper attempts to diagnose a case of cemento-ossifying fibroma of the jaw not only based on clinical characteristics but also radiographic and histopathologic features as an adjunct. Case: The patient was diagnosed with cemento-ossifying fibroma, presenting its clinical presentation, diagnostic imaging and histopathology features, as well as its surgical treatment. Conclusion: The diagnosis of cemento-ossifying fibroma of the jaw can be established based on clinical, radiographic and histo-pathological features. It is a benign growth, considered to originate from the periodontal ligament and presents as a slow-growing lesion, but may cause deformity if left untreated. However, these tumors may exhibit variations in their neoplastic behaviours. It is often encapsulated and predominantly located in the mandible, and the definitive diagnosis of these lesions requires integration of its clinical, radiological and histological features. We present a case of cemento-ossifying fibroma in relation to the lower left one-third of the face, and its management.

The risk of occult metastasis is related to the method by which the lymph nodes are evaluated. It is possible to reduce the risk of undiagnosed metastasis with accurate imaging techniques and thus probably reduce the number of elective neck treatments. Aims and objectives To assess the accuracy of clinical palpation, CT Scan, Ultrasound and Ultrasound guided FNAC in prediction of lymph node metastasis in oral squamous cell carcinoma so that a suitable surgical neck dissection can be carried out. Methods Ten patients with oral squamous cell carcinoma who underwent 10 neck dissections (4 RND, 6 SOND) were included. All the patients underwent examination of neck pre operatively by palpation, Computed Tomography with contrast, Ultrasound and Ultrasound guided FNAC for no detection. The findings were correlated with the results of histopathologic examination of the neck specimen. The results were obtained after statistical analysis. Results Six neck dissection specimens showed metastatic lymph node involvement in postoperative histopathology. Lymph node involvement was identified preoperatively by palpation in 7 necks, CT in 3 necks, US in 9 necks and US-FNAC was positive in 4 cases. The palpation showed 83% sensitivity, 50% specificity. CT showed sensitivity of 50%, specificity of 100%, US showed sensitivity of 100%, specificity of 25% and US-FNAC showed sensitivity of 67%, specificity of 100%. Conclusion The palpation, CT Scan and US are equally accurate but the US-FNAC is the most accurate technique in assessing metastasis in lymph nodes in patients with oral squamous cell carcinoma.

The prognostic relevance of dysplasia and carcinoma in situ at surgical margins is well documented. Materials and Methods: We evaluated the use of Lugol's iodine in visualizing the surgical margins of dysplastic tissue by an observational study of 100 patients having oral precancerous lesions between June 2013 and March 2016. Conclusion: Lugol's iodine is a simple, inexpensive, and apparently effective means of diagnosing and visualizing the surgical margins of the dysplastic tissue in oral precancerous lesions.

Materials and Methods: All patients with suspected unilateral condylar fractures were initially subjected to a radiologic assessment through a conventional radiographic technique of OPG to select the treatment modality, that is, open or closed. Subsequently, all patients were made to undergo a standard CT scan for the study of the temporomandibular joint, with the same objective, that is, (eighty radiographic imaging: forty OPG + forty CT scan) was done to determine which radiographic technique is more helpful in determining the final clinical diagnosis including treatment planning of suspected unilateral mandible condyle fracture. The findings were compared and cross-checked with those of conventional radiographic analysis. Results: It was found that out of the selected patients of confirmed forty unilateral condylar fractures, 33 patients were indicated for closed reduction by conventional radiography, were revealed to have a lateral extracapsular displacement on CT scan, and hence were treated by open reduction. Seven patients satisfied the criteria for closed reduction, both by conventional radiographs and CT scans. Conclusion: Through this theoretical research, it was found that both radiographic techniques are indispensable, specific, and standard in the detection of mandibular fractures. It was noted that CT scan radiographic information might help alter the approach and the treatment plan and prevent erroneous management in mandibular condylar fractures.

The presence of metastatic cervical lymph nodes histologically positive for SCC provides one of the simplest and most important prognostic factor in patients with head and neck cancer. In this study, all patients were examined clinically for, location, number, size, shape, consistency and fixation of cervical neck nodes to the underlying structure, and the same was carried out by FNAC, USG and CT. Findings of these modalities and histopathological results were compared for the overall metastases of lymph nodes in the neck. The accuracy of clinical examination was 87.77% and sensitivity only 41.66%. FNAC has the greatest specificity, 98.71% and least sensitivity, 33.33%. The accuracy of FNAC was 90%. The positive predictive value and negative predictive value of FNAC were 80.0% and 90.58% respectively. USG revealed 50% of sensitivity. Specificity of USG was 93.58% and accuracy 87.77%. CT scan have the highest sensitivity among all other tests, 66.66%.The negative predictive value for CT scan was also the highest, 94.59%. Specificity and accuracy of CT scan was 89.74% and 86.66% respectively. This study concludes that USG with FNAC is the most accurate in evaluating metastatic lymph nodes in oral squamous cell carcinoma patients along with other investigations like CT scan for staging of the oral squamous cell carcinoma.

Schwannoma of the oral and maxillofacial regions primarily appears in soft tissue with tongue being the common site. Schwannoma arising within the bone are rare and commonly involve the mandible compared to maxilla. In this article, we report a case of rare intra-osseous schwanomma crossing the midline, which presented as a multilocular lesion on radiograph, which is again very rarely seen. Chief complaint of the patient was swelling and pain. Panoramic Radiograph showed a solitary oval shaped radiolucency with corticated borders and scalloping. Biopsy report revealed connective tissue component comprising of hyalinized stroma and tumor cells with large number of siderophages and histiocytes suggesting intra osseous schwannoma. Surgical resection performed and histopathologically examined confirming intra osseous schwannoma of ancient type. The post-operative course of the patient was uneve...

Methods: On evaluation and examination, patients with temporo-mandibular disorders were selected whose impression was taken using Biostar material which was hard in consistency with 0.5mm x 125mm thickness was used to prepare occlusal splint. A total of 10 patients who were included in the study were assessed for pain using visual analog scale and improvement in mouth opening before and after splint therapy for 3 months. The mouth opening and pain were measured before using the splint. The prepared splint was delivered to patients. The patients were advised to use the splint regularly for at least 12 hours a day particularly during night. The mouth opening and pain assessment were done at one month, two month and three month follow up and were compared with base line values. Results: The mean mouth opening at baseline was 35.8±2....

Intra-operatively irrigation of the lesion and its surrounding areas was done with toluidine blue solution for 20 s. Followed by irrigation with 1% acetic acid to remove all the mechanically retained stain. The unstained margins were demarcated using incision placed by no 15 BP blade. The lesion was resected with a safe margin of 1 cm away from the stained tissue. Neck dissection was done according to the nodal status. The tumor along with the resected margins was sent for histopathological examination. Statistical analysis was performed to calculate specificity of the vital stain. The cross tabulation between epithelium of the stained and unstained margins was done and subjected to Chi-square test to calculate the significance. The toluidine blue vital stain has a sensitivity of 93.33%. Out of 15 cases, 2 patients recorded positive excision margins leading to recurrence at primary site; 1 patients recorded positive excision margins leading to recurrence at secondary site; 1 patient recorded free excision margins but had recurrence at secondary site; remaining 11 patients recorded free excision margins and did not have recurrence. Vital staining with toluidine blue is concluded to be specific in demarcating the dysplastic tissue adjacent to the carcinomatous lesion, which when excised along with the adjacent dysplastic tissue leads to a decrease in the recurrence in oral squamous cell carcinoma cases. Furthermore, it is inexpensive, easily available and does not add significantly to the operating time. Moreover, it provides a gross visualization of dysplasia surrounding the lesion especially in cases where in the margins are not well defined. Hence, toluidine blue can be a useful and inexpensive adjunct to identify margins intra-operatively in the current scenario where intra-operative frozen sections are not available.

Study parameters included were assessment of adequacy of anatomical repositioning, fixation and stability of fracture site by radiographs, pre and post-operative occlusion by photographs. Evaluation of anatomical repositioning was done with fracture gap measurement on orthopantomogram after 6 months by applying paired student's T test. In mandibular angle fracture, pre-operatively, the mean of anatomical repositioning fracture gap measurement on orthopantomogram was 4.06 mm with a standard deviation of 1.42 mm and 6 months post-operatively, the mean was 0.5 mm with a standard deviation of 0.32 mm. The P value was \ 0.00001, which shows a very high significant. In sub-condylar fractures, pre-operatively, the mean of anatomical repositioning fracture gap measurement on orthopantomogram was 6.77 mm with a standard deviation of 3.54 mm and 6 months post-operatively, the mean was 1.57 mm with a standard deviation of 2.37 mm. As the sample size was small, P value could not be calculated. The use of the trans-buccal trocar provides adequate anatomical repositioning, fixation, stability, occlusion and good accessibility during placement of plate and screws.
