[Obstructive sleep apnea hypopnea syndrome study on pathogenesis and prognosis]

Area of Science:

• Sleep Medicine
• Respiratory Physiology
• Otorhinolaryngology

Background:

• Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a prevalent sleep disorder.
• Pathogenesis is multifactorial, involving both anatomical and non-anatomical factors.
• Upper airway anatomy is a well-established contributor to OSAHS.

Purpose of the Study:

• To conduct a comprehensive review of current literature on OSAHS pathogenesis.
• To systematically analyze both anatomical and non-anatomical contributing factors.
• To synthesize recent findings on the role of non-anatomic elements.

Main Methods:

• Literature search of domestic and international studies.
• Systematic review and synthesis of research findings.
• Focus on anatomical and non-anatomical factors in OSAHS.

Main Results:

• Non-anatomic factors significantly contribute to OSAHS.
• Key non-anatomic factors include upper airway dilator muscle insufficiency, high loop gain, and low arousal threshold.
• These factors play a critical role alongside anatomical considerations.

Conclusions:

• OSAHS pathogenesis is complex and involves a combination of factors.
• Non-anatomic factors are increasingly recognized as critical in OSAHS development.
• Further research into non-anatomic elements is warranted for improved understanding and treatment.
