Introduction

Obstructive Sleep Apnea (OSA) is a prevalent disorder characterized by repeated episodes of partial or complete upper airway obstruction during sleep. It leads to significant morbidity, including cardiovascular diseases, metabolic syndrome, and decreased quality of life. Traditional treatments such as Continuous Positive Airway Pressure (CPAP) therapy, while effective, often suffer from poor patient compliance. In recent years, endoscopic approaches have emerged as a promising alternative, offering minimally invasive solutions tailored to the anatomical and functional abnormalities underlying OSA [1].

Endoscopic evaluation plays a crucial role in diagnosing the specific sites of airway obstruction in OSA patients. Drug-induced sleep endoscopy (DISE) has become a gold standard, providing dynamic visualization of the upper airway during a sleep-like state. This technique helps identify the collapse patterns at various levels such as the nasal cavity, oropharynx, and hypopharynx. Innovations in endoscopic imaging, including three-dimensional (3D) reconstruction and virtual endoscopy, enhance diagnostic accuracy and facilitate personalized treatment planning [2].

Several endoscopic surgical techniques have been developed to address airway obstructions in OSA. Uvulopalatopharyngoplasty (UPPP) is one of the most common procedures, involving the resection of excess tissue in the oropharynx to widen the airway. More recently, transoral robotic surgery (TORS) has been introduced, allowing for precise tissue removal with reduced morbidity. Endoscopic techniques such as radiofrequency ablation and laser-assisted uvulopalatoplasty offer minimally invasive options with shorter recovery times [3].

Expansion Sphincter Pharyngoplasty (ESP) represents a significant advancement in the surgical management of OSA. This endoscopic technique involves repositioning and tightening the palatopharyngeal muscle to prevent airway collapse. Studies have shown that ESP not only improves airway patency but also preserves speech and swallowing functions, making it a favorable option for many patients [4].

Hypoglossal nerve stimulation (HNS) is an innovative endoscopic technique that targets the neuromuscular control of the tongue. By implanting a stimulation device, this approach activates the hypoglossal nerve, preventing the tongue from collapsing backward during sleep. HNS has demonstrated significant improvements in sleep apnea severity and patient quality of life, particularly for those who cannot tolerate CPAP therapy [5].

Endoscopic balloon dilation is gaining traction as a treatment for nasal obstruction contributing to OSA. This procedure involves inflating a balloon within the nasal passages to widen the airway, enhancing airflow and reducing resistance. Balloon dilation is minimally invasive, with quick recovery times and lasting benefits, particularly for patients with anatomical nasal obstructions [6].

Combining endoscopic techniques with traditional therapies is a growing trend in OSA management. For instance, incorporating endoscopic sinus surgery with CPAP therapy can enhance nasal patency and improve CPAP compliance. Additionally, multimodal approaches integrating endoscopic surgeries with mandibular advancement devices (MADs) offer comprehensive solutions for complex airway obstructions [7].

Endoscopic approaches are also being explored in pediatric populations with OSA, where adenotonsillectomy remains the first-line treatment. For children with persistent OSA post-adenotonsillectomy, endoscopic techniques such as lingual tonsillectomy and epiglottoplasty provide additional treatment options. These minimally invasive procedures are particularly beneficial in reducing the risk of complications and promoting faster recovery in pediatric patients [8].

Technological innovations continue to drive the evolution of endoscopic treatments for OSA. Advancements in endoscopic tools, such as flexible and high-definition scopes, enhance visualization and precision during surgery. Robotic-assisted endoscopic systems offer greater dexterity and control, improving surgical outcomes. Furthermore, the integration of artificial intelligence (AI) in endoscopic procedures holds promise for real-time decision-making and personalized treatment strategies [9].

The future of endoscopic approaches to OSA lies in personalized medicine. Ongoing research aims to refine diagnostic techniques to better identify patient-specific obstruction patterns. Developing less invasive and more effective endoscopic treatments will likely improve patient outcomes and adherence. Additionally, advancements in telemedicine and remote monitoring may facilitate post-operative care and long-term management of OSA [10].

conclusion

Endoscopic approaches are transforming the landscape of OSA management by offering targeted, minimally invasive solutions that address the unique anatomical and functional challenges of each patient. Current trends emphasize the importance of precise diagnosis and tailored treatments, while future directions point towards continued innovation and personalization in OSA care. As technology advances, endoscopic techniques will play an increasingly vital role in improving the lives of those affected by obstructive sleep apnea
