Sleep Apnea01:21

Sleep Apnea

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...
Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...
Sleep-Wake Cycles01:24

Sleep-Wake Cycles

Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and  rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:

Summary

Functional rhinoplasty significantly improves nasal obstruction and sleep quality for adults with sleep-disordered breathing (SDB). This meta-analysis supports its use as an adjunctive treatment for selected patients.

Area of Science:

  • Otolaryngology
  • Sleep Medicine
  • Surgical Outcomes Research

Background:

  • Structural nasal obstruction significantly impacts sleep-disordered breathing (SDB).
  • The quantitative effect of functional rhinoplasty on sleep outcomes remains unclear.
  • Evidence-based guidelines for surgical intervention in SDB require robust data synthesis.

Purpose of the Study:

  • To systematically review and meta-analyze studies on functional rhinoplasty/septorhinoplasty in adults with SDB.
  • To assess the impact of surgery on nasal obstruction and validated sleep-related symptoms.
  • To test the hypothesis of large nasal obstruction improvement and modest sleep symptom improvement.

Main Methods:

  • PROSPERO-registered systematic review and random-effects meta-analysis.
  • Searched PubMed, Embase, and Cochrane Library up to September 2025.
  • Pooled standardized mean differences (SMDs) from 8 studies (1,192 participants).

Main Results:

  • Large improvement in nasal obstruction (Nasal Obstruction Symptom Evaluation SMD: -4.99).
  • Moderate reductions in daytime sleepiness (Epworth Sleepiness Scale SMD: -1.09).
  • Modest gains in sleep quality (Pittsburgh Sleep Quality Index SMD: -0.74) and functional status (FOSQ-10 SMD: 0.41).

Conclusions:

  • Functional rhinoplasty and septorhinoplasty improve nasal obstruction and patient-reported sleep outcomes in adults with SDB.
  • These procedures may serve as adjunctive treatments for carefully selected patients.
  • Further high-quality, phenotype-driven studies are needed to refine effect estimates and selection criteria.
