Background:Histological grading is an important diagnostic tool to predict the clinical and biological behaviour of cancer. Cervical lymph node metastasis indicate poor prognosis of oral cancer. Considering economical status of a third world country, Anneroth's grading system is less expensive, more informative than TNM staging and Broder's grading system. Anneroth's grading system also shows co-relationship with lymph node metastasis. So we are trying to evaluate the Anneroth's grading as a standard one among these three system.Objective:To study the grading of histological malignancy according to Anneroth's classification of biopsy specimens in relation to metastasis in the cervical lymph nodes and comparing the Anneroth's with the other two recognized classifications.Materials and Methods:Fifty(50) patients with oral squamous cell carcinoma was included in the study. Specimen of 35 non-metastatic tumors were compared with 15 metastatic cases. All of the patients were graded to TNM, Broder's and Anneroth's system. TNM is clinical assessment and Broder's is based on only differentiation of cells. On the other hand, six parameters of Anneroth's gives a detail about the morphology of the tumor, invasion criteria in the host tissue and show its correlation with lymph node metastasis. Scoring system of Annearoth's grading indicates demarcation points of worseness of tumor and signifies the possibility of lymph node metastasis.Results:Both Anneroth's(P=0.002) and Broder's grading(P=0.012) have been significant but Anneroth's one is more significant then Broder's.Conclusion:Anneroth's classification can be taken as a standerd diagnostic factor and predictive factor of lymph node metastasis.

Maxillofacial surgeons often deal with many cases of delayed wound healing, some are related to known risk factors and some are unknown. This study was aimed to assess the histological features of wound healing on day 0 and day 7 in postoperative cases of maxillofacial region in patients with or without risk factors. histological examination of tissue specimen was done on day 0 and day 7. Based on six histological parameters, microscopic examination of tissue specimen was done by both routine Haematoxylin and Eosin stain and Masson's Trichrome stain. In day 7, healing wound of study group having risk factors showed profound amount of granulation tissue, early collagen fibres, plenty inflammatory infiltrate, vertical orientation of reticular pattern of collagen and minimum amount of mature collagen in majority of patients which indicates delayed healing.On the other hand, in control group majority showed horizontally oriented mature collagen fibres in fascicle. Statistically, significant association was found between study and control subjects in terms of pattern of collagen tissue, amount of early and mature collagen tissue at the 7 th day of follow up. Clinical evaluation also had strong association with histological state of healing.

Introduction Malignancies of the tongue represent one of the greatest management challenges for the maxillofacial surgeons as well as oncologists, because of the adverse effects of treatment on oral and pharyngeal function, the eventual quality of life, and the poor prognosis of advanced disease. Therefore, it is important to use judgment and experience in determining the best method of treatment. Material and methods We reviewed forty cases of oral tongue cancer patients admitted in the Dental and Facio-

Temporalis muscle transfer is a versatile technique frequently used for reconstructive procedures in the maxillofacial region. However the thickness of the pedicle may interfere with masticatory function when used anteriorly in the oral cavity. To repair fulllength mid-palatal defects in fully dentate patients the flap can be passed through the maxillary sinus and combined with local repair of the soft palate, thus avoiding any occlusal trauma from the posterior teeth. The operation is a single stage procedure with low morbidity and few complications, and is a useful technique for repairing the large untreated clefts frequently encountered in developing countries. The procedure is used by members of the Australian and New Zealand Association of Oral and Maxillofacial Surgeons Bangladesh Project who have operated in Dhaka teaching hospitals on a regular basis since 1991.
