Use of narrow band imaging guidance in the management of oral erythroplakia
No full textErythroplakia is an epithelial lesion that holds the highest risk of showing severe dysplasia or microinvasive carcinoma. The gold standard treatment is total excision to obtain a complete histopathological diagnosis. Traditionally this has been done by illumination of the lesion with white light, and resection with adequate margins. The difficulty with erythroplakia is that margins can be hard to delineate precisely, and even severe dysplasia can be seen with only subtle changes in the surface mucosa.
Narrow band imaging is a novel technique that enhances the diagnostic potential of endoscopy. It highlights abnormalities in the superficial vasculature, which means that lesions such as oral erythroplakia can be identified more easily. We report its use in the identification of the full extent of lesions, and show its intraoperative advantages in obtaining resection margins free from disease
The role of narrow band imaging in early detection of head and neck cancer
No full textNarrow band imaging (NBI) is a novel method of imaging that increases the diagnostic potential of conventional endoscopy. It highlights abnormalities in the superficial vasculature of mucosal lesions so that precancerous or cancerous lesions can be identified more easily. Initially developed for the gastrointestinal tract, and widely used in other branches of medicine, it is now being used for the assessment of patients with malignancy in the head and neck. We review current published papers relating to NBI and discuss its benefits for early detection of cancer of the head and neck
Debulking of free myocutaneous flaps for head and neck reconstruction using an arthroscopic shaver
No full textMost reconstructive surgeons prefer a myocutaneous free flap for head and
neck reconstruction due to its bulk and superiority in bacterial suppression. To
obtain proper symmetry and contouring in the head and neck region, ancillary
procedures usually have to be performed. Eleven head and neck cancer patients
underwent resection and reconstruction with myocutaneous flaps that resulted in
unacceptable facial contouring. Delayed flap debulking with an arthroscopic shaver
was performed. All 11 patients were satisfied with their facial contouring and
symmetry after one session of debulking. There were no complications such as flap
necrosis, seroma or haematoma. This novel technique done under local anaesthesia
is effective for debulking myocutaneous free flaps and removing fibrotic tissues. It is
simple, safe and produces a reliable and satisfactory outcome

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
