Of the 42 cases, adequate material for cytologic evaluation was obtained in 35 cases. Malignant cells were found in 9 of 35 cases. FNAB diagnosis was confirmed by histopathology in all 9 of these specimens (100% accuracy). The FNAB diagnosis of benign lesions was confirmed in 19 of 26 cases (73% accuracy). The most common benign lesions were odontogenic cysts, followed by fibro-osseous and giant cell lesions. Incorrect diagnosis was related to lack of architectural context of the FNAB material, inadequate quantity of the aspirate and sampling of a non-representative part of a large lesion. Thus FNAB is a useful, simple, fairly reliable and outpatient procedure for diagnosis of intra-osseous jaw lesions, especially to distinguish between malignant and benign jaw lesions.

It has played a significant role in the development of human culture and society. More over it contains very rich components of biodiversity of local, national, and regional significance. They also provide habitat for a variety of resident and migratory waterfowl, a significant number of endangered species, and a large number of commercially important species. Mangrove wetlands are unique environments of floral-faunal assemblages, providing a complex detritus-based food-web for a number of marine and brackish water organisms. Wetlands in Bangladesh have great importance for the country’s economic, industrial, ecological, socioeconomic, and cultural aspects. There are five types of wetlands available in Bangladesh, such as saltwater wetlands, freshwater wetlands, palustrine wetlands, lacustrine wetlands, and manmade wetlands. There are 43 designated wetlands, and some are under threat from indiscriminate utilization, encroachments and reclamation, urbanization and drawbacks from agricultural development, and flood control. Almost 50% of the country’s people are directly dependent on wetlands resources. The vast majority of the poor people in the wetlands areas are dependent on wetlands resources for their nourishment. Wetlands have potential and have been recognized as a driving force for biodiversity conservation and rural socioeconomic improvement. Smart-use of wetlands can solve the ecosystems problems in the floodplain areas. A comprehensive analysis of the various issues leading to wetlands degradation is made in this study. The country needs an adequate interdisciplinary policy and political will to implement it for sustainable management and protection of wetlands and ecologically sensitive ecosystems in Bangladesh. Therefore, a reliable data bank is provided in this study to enhance the conservation measures initiated by the Government.

A provisional diagnosis was made after clinical assessment and radiological investigations, but final diagnosis was made after histopathological examination. The incidence of masses in NC, PNS, and NP was 34.3 cases per year, non-neoplastic lesions constituted 60% of these cases and their incidence was 20.7 cases per year. All the cases were carefully examined histopathologically and it was found that the region was affected by a variety of non-neoplastic lesions. Among 240 cases, 145 were non-neoplastic and 95 were neoplastic The lesions in the decreasing order of frequency were - nasal polyp, rhinoscleroma, tuberculosis, fungal infection, fibrous dysplasia, ossifying fibroma, cysts, nasal glioma, and cemento-ossifying fibroma. NP was involved by a range of neoplastic lesions; however, no non-neoplastic lesion was seen in this region.
