“…Only FRIEDMAN et al [252] included more obese patients (BMI ,40 kg?m -2 ). The six case series showed a reduction of the AHI .50% and postoperative AHI ,10 in 15-50% of the cases 3-15 months after the procedure [250][251][252][253][254]. Both randomised, placebocontrolled, double-blind studies show a superiority of implants over placebo.…”

“…Recently, there have been several studies investigating the efficacy of palatal implants in OSA patients. Apart from prospective case series with longer follow-up periods [9,10], there have been two placebo-controlled trials undertaken in the United States [4,13]. In those trials, the results regarding the effects on objective outcome measures are conflicting, although they both demonstrated a superiority of palatal implants over placebo.…”

Palatal implants have been used to treat snoring and mild to moderate obstructive sleep apnea (OSA). Two previous controlled trials have published conflicting results regarding the effects of palatal implants on objective outcome measures, although they both could demonstrate superiority over placebo. The aim of the present study was to assess the effects of palatal implants in patients with mild to moderate sleep apnea in a randomised, placebo-controlled trial. Twenty-two patients with mild to moderate OSA (AHI 18 ± 5, BMI 28 ± 3, age 51 ± 13 years) due to palatal obstruction were enrolled in this randomised, double-blind, placebo-controlled trial. Respiratory parameters and sleep efficiency (evaluated by polysomnography), snoring (evaluated by the bed partner), and daytime sleepiness (evaluated by ESS) were assessed before and 90 days after surgery. One patient in each group did not show up for follow-up. The AHI, HI and LSAT showed statistically significant improvement in the treatment group (p < 0.05). Snoring as rated by bed partners also showed statistically significant improvement within the treatment group (p = 0.025). There was no statistical difference when comparing the means of the treatment group with the placebo group. There were no peri- or post-operative complications and no extrusions during the follow-up period. The study supports the idea that palatal implants lead to a reduction in respiratory events in patients with mild to moderate OSA, although a statistically significant superiority of palatal implants over placebo could not be demonstrated in this trial.

“…The results in this study were comparable with previous studies. Nordgård et al [25] showed that 50% of 26 patients had at least 50% reduction to an AHI less than 10 events per hour after follow-up for 1 year. Walker et al [26] revealed that were no obvious factors that predicted the long-term results of OSA after this procedure in previous studies.…”

Successful results of palatal implants in the treatment of obstructive sleep apnea (OSA) have been reported in the short term; however, there are limited data in the long-term results. The aim of this study was to evaluate the long-term results and to determine factors that predicted the responders in patients undergoing palatal implants in the treatment of OSA. A study was undertaken on 92 OSA patients. Palatal implants were conducted to stiffen the soft palate and data were analyzed. Patients tolerated the procedure well. They were examined between 26 and 32 months after the operation (mean 28.9 ± 4.8). Age range was 25-65 years (38.4 ± 10.5) and BMI was 27.3 ± 2.4 kg/m. The mean preoperative ESS score was 12.3 ± 2.6 and long-term ESS was 7.9 ± 1.8 (p < 0.001). The mean VAS for snoring in the baseline was 8.2 ± 1.2 and long-term VAS was 3.8 ± 2.3 (p < 0.001). The mean preoperative LSAT and long-term LSAT were 87.4 ± 6.7 and 89.2 ± 4.8%, respectively (p < 0.01). The mean AHI decreased from 21.7 ± 6.8 to 10.8 ± 4.8 (p < 0.001). Forty-eight (52.2%) patients had long-term surgical response. Responders had significantly lower preoperative BMI, AHI, and MMP level than non-responders. Implant extrusion occurred in seven patients (7.6%) and palatal abscess in one patient (1.1%). Bleeding and airway obstruction were not encountered. Palatal implants in carefully selected patients suffering from mild OSA, give fairly good long-term results and have a low complication rate.
