SummaryOral squamous cell carcinoma (OSCC) is the most common cancer of the oral cavity and constitutes 95% of all cancers of this area. Men are affected twice as commonly as women, primarily if they are over 50 years of age. Forty percent of the lesions are localized in the tongue and 30% in the floor of the oral cavity. OSCC often affects upper and lower gingiva, buccal mucous membrane, the retromolar triangle and the palate. The prognosis is poor and the five-year survival rate ranges from 20% (OSCC in the floor of the mouth) to 60% (OSCC in the alveolar part of the mandible). Treatment is difficult, because of the localization and the invasiveness of the available methods. The diagnosis is made based on a histopathological examination of a biopsy sample.The low detection rate of early oral SCC is a considerable clinical issue. Although the oral cavity can be easily examined, in the majority of cases oral SCC is diagnosed in its late stages. It is difficult to diagnose metastases in local lymph nodes and distant organs, which is important for planning the scope of resection and further treatment, graft implantation, and differentiation between reactive and metastatic lymph nodes as well as between disease recurrence and scars or adverse reactions after surgery or radiation therapy.Imaging studies are performed as part of the routine work-up in oral SCC. However, it is difficult to interpret the results at the early stages of the disease. The following imaging methods are used – dental radiographs, panoramic radiographs, magnetic resonance imaging with diffusion-weighted and dynamic sequences, perfusion computed tomography, cone beam computed tomography, single-photon emission computed tomography, hybrid methods (PET/CT, PET/MRI, SPECT/CT) and ultrasound. Some important clinical problems can be resolved with the use of novel modalities such as MRI with ADC sequences and PET.The aim of this article is to describe oral squamous cell carcinoma as it appears in different imaging methods considering both their advantages and limitations.

Background: Surgical defects of oral cavity and orofacial region are challenging because of the aesthetic and functional demands and dynamic nature of the area. A multitude of reconstructive options are available and with the advent of musculocutaneous flaps and free microvascular tissue transfer, orofacial reconstruction has entered an era of sophistication whereby repair of defects of all types and sizes has become possible. Objectives: This study was conducted to evaluate the functional outcome, surface texture and complications of nasolabial flap for reconstruction in the buccal mucosal defects. Materials and Methods: A cross-sectional observational study was conducted 20 patients with clinical histological diagnosed squamous cell carcinoma (SCC;T1-T3 ) involving buccal mucosa attending in the Oral and Maxillofacial Surgery department of Dhaka Dental College and Hospital during this study period were included purposively in the study. All patients were treated by excision of the lesion and subsequent reconstruction of the defect by nasolabial flap. If indicated then patients received adjuvant radiotherapy. They were examined preoperatively, immediate postoperatively, on discharge and 3 months after operation. Data were analyzed by SPSS statistics (version 20) software. To find out the significance of the result one way ANOVA was conducted and the Post Hoc Test was done by LSD. Results: Among 20 patients 15% (3) patients developed infection, 15% (3) patients developed dehiscence. Trismus occurred in 5% (1) patient. In assessment of interincisal opening of the patients, 90% (18) presented with adequate interincisal opening but it has been reduced in 10% (2) patients after radiotherapy. In 90% (18) patients surface texture of the flap were smooth and in 10% (2) were partially smooth. Conclusion:The nasolabial flap has proved to be a useful and reliable option for reconstruction of defects of the buccal mucosa in order to allow wound closure without tension and maintain oral function.

Bone invasion in oral cancer patients: A comparison between Orthopantamograph, conventional computed tomography, and single positron emission computed tomography

Abstract: The present study showed that SPECT was highly sensitive, but with a very low specificity due to an increase in false positive values. However, OPG and conventional CT showed an acceptable degree of sensitivity and specificity.
