title: A new technique using a nasal cast for anterior rhinomanometry.
abstract: A new method of sealing a pressure sensing tube into the nostril for anterior rhinomanometry is described. This involves the use of a nasal cast made from dental impression material. The results demonstrate that the nasal cast technique gives the same resistance values as the standard nasal tape technique. Obstruction of one nostril with a nasal cast for fifteen minutes is shown to have no effect on nasal resistance. The advantages of the nasal cast method compared with the nasal tape method are described.
