Polytetrafluoroethylene - Polytetrafluoroethylene, brand name Gore-Tex, is used in plastic surgery and other operations is known by an abbreviation of its chemical name, ePTFE (expanded polytetrafluoroethylene) or Gore S.A.M. (subcutaneous augmentation material). [12]
Non-surgical rhinoplasty is reported to have originated at the turn of the nineteenth century, when New York City neurologist James Leonard Corning (1855–1923) and Viennese physician Robert Gersuny (1844–1924) began using liquid paraffin wax to elevate the "collapsed nasal dorsum" that characterizes the "saddle nose deformity."
The term secondary rhinoplasty denotes the revision of a failed rhinoplasty, an occurrence in 5–20 per cent of rhinoplasty operations, hence a revision rhinoplasty. The corrections usual to secondary rhinoplasty include the cosmetic reshaping of the nose because of a functional breathing deficit from an over aggressive rhinoplasty, asymmetry ...
Gore-Tex is W. L. Gore & Associates's trade name for waterproof, breathable fabric membrane. It was invented in 1969. It was invented in 1969. Gore-Tex blocks liquid water while allowing water vapor to pass through and is designed to be a lightweight, waterproof fabric for all-weather use.
The exact mechanism of action of silicone gel sheeting has not been fully studied. Currently, many proposed mechanisms explain the efficacy of such treatment, including the occlusion and hydration effect, increased body surface temperature, polarized electric charge, immunological effects, etc. [9] The occlusion and hydration effect is the most studied mechanism of action.
Silicone rubber is an elastomer (rubber-like material) composed of silicone—itself a polymer—containing silicon together with carbon, hydrogen, and oxygen. Silicone rubbers are widely used in industry, and there are multiple formulations.
Nasal surgery is a specialty including the removal of nasal obstruction that cannot be achieved by medication and nasal reconstruction. Currently, it comprises four approaches, namely rhinoplasty, septoplasty, sinus surgery, and turbinoplasty, targeted at different sections of the nasal cavity in the order of their external to internal positions.
A closed membrane like Sympatex differs from microporous membranes (such as Gore-Tex) which have microscopic pores that let air (and water vapour) pass through, yet have such low surface energy that the surface tension of any (liquid) water in contact remains too high to allow it to squeeze through the pores. Microporous membranes have ...
