  • (2) In all cases the Blom-Singer duckbill prosthesis was utilized for alaryngeal voice restoration.
  • (3) Thirteen of 20 who had adequate follow-up developed fluent, intelligible speech using either duckbill or low-pressure one-way valves.

  • (5) Tracheoesophageal voice produced with a low pressure prosthesis had greater amounts of periodic phonation than tracheoesophageal voice produced with a duckbill prosthesis.
  • (6) A single motion with a double-action duckbilled rongeur produces a smooth-walled, symmetrical aortotomy which varies in shape predictably according to the angle at which the rongeur is held relative to the axis of the aorta.

  • (5) Bile salts of the sturgeons Acipenser guldenstaedti Brandt, Acipenser stellatus Pall and Huso huso L. and of the paddlefish Polyodon spathula Walbaum are shown to be closely similar, consisting mainly of taurocholate with minor amounts of tauroallocholate and the monosulphates of bile alcohols.
