For a decade after the 1972 Rimini Symposium, a tracheostomy had been the best treatment available for severe sleep apnea; now, continuous positive airway pressure (CPAP) has replaced tracheostomy as the primary therapy for sleep apnea.
Sullivan et al2 compared the two therapies in 1983. The difficulties of life with a tracheal stoma far outweigh the inconvenience of the CPAP compressor used at night.
