Background: Surgical palatal techniques are established alternatives to continuous positive airway pressure (CPAP) in selective patients with obstructive sleep apnea (OSA) with retropalatal airway collapse. Anterior palatoplasty (AP) stiffens and advances the soft palate, whereas radiofrequency-assisted uvulopalatoplasty (RF-UPP) uses thermal ablation to reduce palatal tissue. This study aimed to compare the 6-month efficacy and morbidity of AP vs. RF-UPP in treating mild-to-moderate OSA. Materials and Methods: We conducted a single-center retrospective cohort study (March 2023–March 2025) of 86 adults (mean age ~42 years; 69.8% male) with mild-moderate OSA (apnea–hypopnea index [AHI] 5–30) due to palatal obstruction; 43 patients underwent AP and 43 patients underwent RF-UPP. Polysomnographic AHI, Epworth sleepiness scale (ESS), snoring severity (0–10 visual analog scale, VAS) and sleep-related quality of life (functional outcomes of sleep questionnaire, FOSQ) were analyzed at baseline and 6 months postoperatively. Postoperative pain (0–10 VAS), recovery time, and bleeding events were also assessed. Results: Baseline characteristics were similar between groups (AHI ~22 vs. 21 events/h; ESS ~11 vs. 10; snoring VAS ~8.4 vs. 8.2 in AP vs. RF-UPP, all p > 0.1). At 6 months, the AP group achieved a greater mean AHI reduction than the RF-UPP group (−13.5 ± 7.5 vs. −8.0 ± 7.2, p < 0.001), with post-treatment AHI averaging 8.5 ± 6.0 vs. 13.2 ± 6.5 events/h (AP vs. RF-UPP). AP yielded a higher surgical success rate (34/43 (79.1%) vs. 23/43 (53.5%), p = 0.012), meeting the criteria of ≥50% AHI reduction to <15; p = 0.01. Subjective outcomes improved in both groups, but AP showed greater mean reductions in ESS (−5.5 vs. −3.1 points, p = 0.001) and snoring VAS (−5.7 vs. −3.1, p = 0.002). The improvements in ESS, snoring VAS, and FOSQ scores were observed in both groups, with significantly greater gains after AP. Postoperative pain and time to resumption of normal diet were higher in the AP group. No major complications occurred in either group. Conclusions: Anterior palatoplasty demonstrated superior efficacy to RF-UPP in mild-moderate OSA at the expense of increased postoperative pain and a longer recovery period. AP may offer a greater therapeutic benefit in appropriately selected patients with palatal obstruction. Full article

Obstructive sleep apnea syndrome (OSA) is a multi-factorial disorder, with quite complex endotypes, consisting of anatomical and non-anatomical pathophysiological factors. Continuous positive airway pressure (CPAP) is recognized as the first-line standard treatment for OSA, whereas upper airway (UA) surgery is often recommended for treating OSA patients who have refused or cannot tolerate CPAP. The main results achievable by the surgery are UA expansion, and/or stabilization, and/or removal of the obstructive tissue to different UA levels. The site and pattern of UA collapse identification is of upmost importance in selecting the customized surgical procedure to perform, as well as the identification of the relation between anatomical and non-anatomical factors in each patient. Medical history, sleep studies, clinical examination, UA endoscopy in awake and drug-induced sedation, and imaging help the otorhinolaryngologist in selecting the surgical candidate, identifying OSA patients with mild UA collapsibility or tissue UA obstruction, which allow achievement of the best surgical outcomes. Literature data reported that the latest palatal surgical procedures, such as expansion sphincter palatoplasty or barbed reposition palatoplasty, which achieve soft palatal and lateral pharyngeal wall remodeling and stiffening, improved the Apnea Hypopnea Index, but the outcome analyses are still limited by methodological bias and the limited number of patients’ in each study. Otherwise, the latest literature data have also demonstrated the role of UA surgery in the improvement of non-anatomical factors, confirming that a multidisciplinary and multimodality diagnostic and therapeutical approach to OSA patients could allow the best selection of customized treatment options and outcomes.

Current treatment modalities for snoring may include mucosal removal, coblation or radiofrequency palatoplasty, injection snoreplasty and placement of palatal implants with described disadvantages. We introduce a new laser assisted method avoiding intraoral injury. A pilot study treating 13 loud snorers having an RDI < 8 was conducted. A diode laser coupled to a flexible fiberand a handle with curved needle was used. The fiber was introduced into the nasal surface of soft palate between palatoglossal and glossopharyngeal arches and advanced progressively anteriorly after pulling the uvula forward three times to create palatal scarring and stiffening. All responded to a phone survey. Six patients reported significant improvement, 4 had some improvement, 2 had mild improvement and one patient had no change. Pain score was moderate for 3 patients while the rest had mild pain. The laser harbors many advantages over other methods. Results with this technique are encouraging further studies. Full article
