Resumo The objective of this study was to observe the change in CPAP pressure after nasal and/or tonsil surgery in a retrospective study involving 17 patients unable to tolerate CPAP titration. All patients had two polysomnography studies for titration: one before and another subsequent to upper airway surgical treatment. the results showed a mean age of 49 +/- 9 years, a body mass index of 30 +/- 4 kg/m(2) and an apnea-hypopnea index of 38 +/- 19. Surgical procedures were radiofrequency reduction of the inferior turbinate (eight patients), septoplasty (one patient), septoplasty with inferior turbinectomy (two patients), septoplasty with inferior turbinate submucosal diathermy (two patients), septoplasty with tonsillectomy (two patients), septoplasty with inferior turbinate submucosal diathermy and tonsillectomy (one patient) and tonsillectomy (one patient). CPAP titration before and after surgery had respectively a mean pressure of 12.4 +/- 2.5 and 10.2 +/- 2.2 cmH(2)O (P = 0.001). Maximum CPAP pressure was 16.4 cmH(2)O before and 13 cmH(2)O after surgery. A pressure reduction >= 1 cmH(2)O occurred in 76.5% of the patients and >= 3 cmH(2)O in 41.1%. Upper airway surgical treatment appears to have some benefit by reducing nasal CPAP pressure levels. the effect seems to be greater when the prior pressure was >= 14 cmH(2)O.
