“…Recent updated analysis reveals that the lack of laryngeal collapse is a considerable success predictor for pharyngoplasty and preoperative low-grade tonsils predict failure of pharyngoplasty, which supports our results. 10 Taken together, we conclude that, through the novel ML technique, the surgical success rate for OSA is ultimately dependent on tonsil grade and epiglottis (DISE) regardless of the type of nasal or palate surgery.…”

Many surgical techniques have been devised to treat snoring. One of them is the uvulopalatal flap (UPF) technique which removes only the mucous membrane of the palate and uvula.Palatal muscle resection (PMR) is a procedure where the levator veli palatini or palatoglossus muscle is cut, and a simple short anastomosis is performed. The purpose of this study was to determine, through state-of-the-art machine learning (ML) techniques, which factors influence the success of surgery in patients who had been operated to treat obstructive sleep apnoea (OSA) using UPF or PMR.

“…12 Reports of the PSG results of version 6 of the LP are rare. According to Elsobki 35 (2021), version 6 proved to be effective when verifying that the median of the AHI decreased considerably from 41.2 to 9.5. A total of 60 percent of the patients experienced a preoperative AHI reduction greater than 50%, with a postoperative AHI < 20.…”

“…There are several treatment modalities for OSA, and they can be divided into non-surgical and surgical. 35 Among the surgeries, oropharyngeal and skeletal, palatal procedures, and neurostimulation of the hypoglossal nerve stand out. Oropharyngeal surgeries have shown exponential evolution in recent years, especially those involving the lateral pharyngeal wall.…”

Introduction Lateral pharyngoplasty (LP) has shown promising results. Craniofacial deformity reduces the pharyngeal space, contributing to the etiopathogenesis. The analysis of craniofacial features can be performed using cephalometry. Objective To verify if craniofacial deformity is associated with worse polysomnographic data in patients with obstructive sleep apnea (OSA), and to verify if the preoperative cephalometric parameters can interfere with the surgical success of the LP. Methods The study included 21 patients with OSA aged between 18 and 65 years who underwent LP in a university hospital from 2015 to 2019. Polysomnography was performed postoperatively, after a minimum period of 6 months from the surgical procedure. In addition, a cephalometric evaluation was performed to assess craniofacial deformity, and to correlate it with the polysomnographic results. Results The mean and median of all polysomnographic respiratory parameters improved postoperatively, especially the apnea-hypopnea index (AHI), which went from 40.15 to 16.60 events per hour (p = 0.001). Of the 21 patients, 15 showed improvements in the AHI postoperatively. As for the cephalometric evaluations, we found that the longer the distance between the hyoid bone and the mandibular plane, the greater the patient's preoperative AHI (p = 0.011). When assessing whether cephalometric changes related to craniofacial deformities influence the surgical outcome of LP, no correlation was found for any cephalometric measurement. Conclusion The longer the distance between the hyoid bone and the mandibular plane, the greater the preoperative AHI, and LP was an effective OSA treatment. Cephalometric variables are not able to modify or determine the success of LP in apneic patients in the population assessed.

(1) Background: This narrative review aims to explore the predictors of success for pharyngeal surgery in the treatment of obstructive sleep apnea (OSA). An extensive literature search was conducted, identifying relevant studies published up to June 2023, utilizing various databases and key search terms related to OSA, surgical interventions, and predictors of success. The review encompasses both retrospective and prospective studies, case series, and cohort studies to provide a broad understanding of the topic; (2) Methods: Review of English scientific literature on phenotypes of OSA related to predictors of success of pharyngeal surgery; (3) Results: Of 75 articles, 21 were included, in these the following were determined to be factors for surgical success: body mass index (BMI) (8 articles), apnea/hypopnea index (AHI) (8 articles), cephalometry (8 articles), palatine tonsil size (7 articles), Modified Mallampati score (2 articles), genioglossus electromyography (2 articles), Friedman score or upper airway anatomy (3 articles), nasopharyngolaryngoscopy (2 articles), drug-induced sleep endoscopy (DISE) (1 article), oral cavity anatomy (1 article) and oxygen desaturation index (ODI) (1 article); (4) Conclusions: The lack of standardized protocols for the indication of pharyngeal surgery is a reality, however identifying known predictors of surgical success may facilitate homogenizing indications.
