“…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.

“…[5][6][7][8][9] However, the number of studies investigating the reliability and longterm results is limited. Neruntarat [10] followedup their patients for 26 and 32 months.

Objectives: This study aims to investigate the long-term efficiency and reliability of the Pillar Implant (PI) procedure. Patients and Methods:Between January 2008 and January 2010, a total of 27 patients (16 males, 11 females; mean age 45.8±7.2 years; range 31 to 58 years) who were diagnosed with low obstructive sleep apnea syndrome and simple snoring underwent the PI procedure in this retrospective, nonrandomized study. The patients were evaluated preoperatively with visual analog scale (VAS) scores in terms of snoring, dysphagia, mouth dryness, foreign body sensation, and pain at the first month, third month, and sixth year intervals.Results: Based on the snoring scale, VAS scores were statistically significantly lower in the first month, third month and sixth year compared to preoperative scores (p=0.001, p=0.008, p=0.017, respectively). There was no pain in any patients beyond the third day. The VAS score averages in all evaluations were higher by statistical significance relative to the preoperative averages (p=0.018, p=0.027, p=0.025, respectively). Mouth dryness was encountered in seven patients. It persisted in seven patients at the third month and in five patients at the sixth year interval. The VAS score averages were statistically significantly higher in all evaluations compared to the preoperative scores (p=0.017, p=0.018, p=0.042, respectively). Conclusion:Pillar implant is an efficient, reliable method in the long-term; however, it should be considered that it could cause complaints such as dysphagia, foreign body sensation, and mouth dryness.Keywords: Obstructive sleep apnea syndrome; pillar implant; snoring. ÖZ Amaç: Bu çalışmada pillar implant (Pİ) işleminin uzun dönem etkinlik ve güvenilirliği araştırıldı. Hastalar ve Yöntemler:Bu nonrandomize retrospektif çalışmada Ocak 2008 -Ocak 2010 tarihleri arasında düşük obstrüktif uyku apne sendromu ve basit horlama tanısı konan toplam 27 hastaya (16 erkek, 11 kadın; ort. yaş 45.8±7.2 yıl; dağılım 31-58 yıl) Pİ işlemi uygulandı. Ameliyat öncesi hastaların görsel analog ölçeği (GAÖ) değerleri horlama, yutma güçlüğü, ağız kuruluğu, yabancı cisim hissi ve ağrı açısından, ilk ay, üçüncü ay ve altıncı yılda değerlendirildi. Bulgular: Horlama skalasına göre GAÖ değerleri, ameliyat öncesi değerler ile karşılaştırıldığında ilk ay, üçüncü ay ve altıncı yılda istatistiksel olarak anlamlı derecede düşük bulundu (sırasıyla, p=0.001, p=0.008, p=0.017). Üçüncü gün sonrasında hiçbir hastada ağrı yoktu. Tüm değerlendirmelerde GAÖ değer ortalamaları ameliyat öncesi ortalamalara göre istatistiksel anlamlı olarak yüksekti (sırasıyla, p=0.018, p=0.027, p=0.025). Ağız kuruluğu ile yedi hastada karşılaşıldı. Bu durum yedi hastada üçüncü ayda ve beş hastada altıncı yıl aralığında devam etti. Tüm değerlendirmelerde GAÖ değer ortalamaları ameliyat öncesi değerleri ile karşılaştırıldığında istatistiksel anlamlı olarak yüksek bulundu (sırasıyla p=0.017, p=0.018, p=0.042).Sonuç: Pillar implant uzun dönemde etkin, güvenilir bir yöntemdir; ancak disfaji, yabancı cisim hiss...

“…Studies that have investigated the efficacy of uvulopalatal flap with tonsillectomy for OSA have shown a significant improvement of the severity of OSA and quality of life [161][162][163][164][165][166][167]. However, it has to be kept in mind that surgical success rates decrease with increasing BMI and AHI in general [168]. Due to a lack of evidence, uvulopalatal flaps are not recommended to treat simple snoring, but can be appropriate for OSA in patients with palatal obstruction.…”

Obstructive sleep apnea (OSA) is a common disorder associated with cardiovascular morbidity. Various methods are offered to improve symptoms of OSA and its outcome. Although positive airway pressure is the most effective treatment for OSA, its clinical effectiveness is limited by patients' compliance. Other suggested treatments for OSA focus on expanding upper airway and reducing its collapsibility. For example, mandibular advancement device (MAD) achieves this goal by mechanically protruding the mandible. Other available treatments including weight reduction, positional therapy, drugs, nasal dilators, and nasal expiratory pressure device are clearly inferior to CPAP.
