Full-thickness nasal deformities are a reconstructive challenge. Restoration of a reliable internal lining is critical for a successful reconstruction. Septal hinge flaps are the workhorse for internal lining defects. However, these and other intranasal mucosal flaps are sometimes unavailable due to prior harvest or previous oncologic resection. We present the two-stage interpolated subcutaneou...

Historically, external skin is the most obvious tissue deficiency after nasal trauma or skin cancer excision. The loss of underlying support and lining is less apparent and practically speaking has been considered an afterthought in the repair of nasal defects. The importance of lining was initially recognized by Keegan and Gillies. Modern surgeons can effectively employ both traditional techni...

The histologic pattern of OKC is distinct and hence the cyst has potential for more aggressive behaviour than other cysts of the jaws. When inflammation is present within the cyst wall of an OKC, the character of the cyst lining changes from the classical pattern to a non-keratinized stratified squamous lining typical of other inflammatory cysts. This transformation often occurred quite abruptl...

Planning for supply water demands (drinkable and irrigation water demands) is a necessary problem. For this purpose, three subjects must be considered (optimization of water supply systems such as volume of reservoir dams, optimization of released water from reservoir and prediction of next droughts). For optimization of volume of reservoir dams, yield model is applied. Reliability of yield mod...

permeability is a key parameter in reservoir characterization. in fact, without accurate information about reservoir permeability, there is no good solution for reservoir engineering problems. up to now, permeability values of a reservoir have been calculated through laboratory measurements or well testing methods. these methods are useful but they cannot describe a reservoir reliably and preci...

Reservoir operation involves many critical decisions due to unpredicted circumstances, such as drought or flood. The reservoir water release decision is one of the challenging tasks for the reservoir operator since the decision to deal with many complicated decision variables and multipurpose operation. Typically, the water that flow into the reservoir comes from the upstream river network. The...

the chemical surfactant flooding can mobilize the trapped oil by lowering the interfacial tension between oil and brine and in some cases altering the reservoir rock wettability. in this work, the effect of surfactants on oil/brine interfacial tension was experimentally investigated. first, the effect of surfactants concentration was surveyed. afterwards, the effect of salinity on surfactant be...

Low permeability tight gas resources account for 90% of the Xihu Sag. Under background extensive development low and reservoirs, key to economic effective is find sweet reservoir formation. To clarify origin distribution a in study area, it important formation evolution mechanisms chlorite. In this study, based on analysis thin section, X-ray diffraction SEM, through factors authigenic chlorite...

Ali Hendi, MD, has indicated no significant interest with commercial supporters. A n 80-year-old woman underwent surgery to treat primary basal cell carcinoma on the right nasal ala. The tumor measured 0.9 Â 0.4 cm and appeared to involve the nasal lining (Figure 1). Tumor-free margins were obtained after the first stage of Mohs micrographic surgery. A 1.3 Â 0.6-cm defect involving 2 mm of the ...

Obviously, restoring the nasal lining is a great challenge in the reconstruction of nasal defects. Full thickness nasal defects usually require special flaps for reconstructing the nasal lining. Intranasal mucosal flaps, hinge over flaps, perinasal second flaps, folded or second forehead flaps and finally free flaps are examples that can be used for this purpose. Moreover, the case presented in...
