Objective:
To evaluate the initial short-term effectiveness of palatal implants in treating patients with mild to moderate obstructive sleep apnea (OSA). Previous published studies have focused on snoring without OSA.
Study Design:
A prospective, nonrandomized study of 25 previously untreated patients with an apnea-hypopnea index (AHI) of 10 to 30 and a body mass index (BMI) of
Results:
The AHI was reduced from a mean of 16.2 to a mean of 12.1 (P < 0.05) for the study group. Twenty of 25 patients (80%) experienced a decrease in the AHI. Twelve of 25 patients (48%) showed a post-90-day implant AHI of 10 or less, a benchmark for the possible cessation of continuous positive airway pressure therapy. The Epworth Sleepiness Score decreased from 9.7 to 5.5 (P < 0.001) and the visual analog Scale of snoring intensity reported by bed partners decreased from 8.4 to 4.3 (P < 0.001).
Conclusion:
The palatal implant method can significantly improve AHI and other sleep-related parameters in patients with mild to moderate OSA and a BMI of
Ebm Rating:

Oxygen Delivering System I: Nasal Cannula and Face Mask
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
