RESUMEN
Polysomnography is currently considered as the gold standard for the diagnosis of obstructive sleep apnea syndrome (OSAS). But high expense and the backlog of the sleep centers have resulted in a search for an alternative method of diagnosis. The aim of this study is to assess the efficacy and reliability of Watch PAT as an alternate option in OSAS diagnosis. The patients have worn a Watch PAT(®) 200 device in the sleep laboratory during a standard polysomnography. The correlation in REM and Non-REM AHI scores, sleep periods and the mean O2 saturation percentage between Watch PAT and PSG sleep studies were assessed. There was a statistically significant very strong correlation between PSG and Watch PAT AHI scores (Spearman's rho = 0.802 p < 0.001). The mean recording time with PSG and Watch PAT was 463.06 ± 37.08 and 469.33 ± 72.81 min, respectively, and there was no statistically significant difference (p = 0.068). However, there was a statistically significant difference between two methods regarding the average sleep time and REM sleep period. No statistically significant difference was revealed in the mean O2 saturation percentage (p < 0.001). Watch PAT is an efficient device and is considered to be an adjunctive diagnostic method for PSG in diagnosis of OSAS.

OBJECTIVES: To assess regrowth potential of the tonsils following partial tonsillectomy performed by using radiofrequency. METHODS: Follow-up results of 42 children (aged from 1 to 10 years) who consecutively had partial tonsillectomy with radiofrequency due to obstructive sleep apnea or snoring were evaluated for regrowth of the tonsils. RESULTS: Regrowth of the remaining tonsillar tissue was observed in 7 of 42 patients (16.6%). The upper respiratory tract obstruction symptoms recurred in 5 of these 7 patients while the remaining 2 patients were asymptomatic. The tonsils of symptomatic patients were removed completely. CONCLUSION: Partial tonsillectomy may have a significant potential for regrowth and thereby recurrence of the obstructive symptoms. Although the cause of this regrowth remains unknown, this problem should be remembered by the surgeons, and an informed consent should be obtained from the families prior to radiofrequency tonsillotomy.
