“…procedures. While wakeful fiberoptic nasopharyngoscopy seems to be of limited use, 10 sleep nasendoscopy shows promise as a technique to locate snoring and has found noise generation at a site other than the soft palate in 30% of adult snorers. 11 This may explain the variability in clinical response to this therapy.…”

(1) The RFTVR palatoplasty is well tolerated with very low morbidity. (2) It is associated with subjective improvement in snoring in most patients. (3) Placement of lesions seems to influence outcome. (4) The improvement is accompanied by a marginal change in objective measurements, suggesting either an acoustic change independent of sound intensity or a placebo effect. (5) A randomized controlled trial is needed to further evaluate this therapy.

Snoring is a common sleep-related behaviour. Increased body mass index (BMI), cranio-facial anatomical features, and older age have been linked to the occurrence of snoring. While mostly middle-aged populations have been studied for the occurrence of snoring and sleep-related breathing abnormality, this study was designed to assess the subjective report of snoring and the objective measurement of snoring at the two extremes of human age.The study design called for measurement of snoring in two age groups (college students; n=155 and older subjects; mean age 64.1 yrs n=134) with a mean age difference of 45 yrs. Snoring was assessed with a validated recording device. A validated questionnaire was used to subjectively assess snoring and obtain relevant sleeprelated information.Students and older subjects differed in the self-report of snoring. While 83% of students reported "never" or "rarely" snoring only 35% of older subjects fell into these categories. Measurement of snoring during sleep revealed that students spent more time during sleep with continuous snoring than older subjects. In older subjects, a reduction in continuous snoring was accompanied by an increase in apnoeic snoring. Subjective snoring frequency correlated with continuous snoring in students only. A positive family history of snoring increased the odds ratio for self-reported snoring but not for recorded snoring.It has been shown that snoring frequency can vary depending on age and that the congruency between perceived snoring frequency and recorded snoring is influenced by the age of an individual. Eur Respir J 1998; 11: 451-457 Over the years snoring has become a focus in sleepdisorder medicine and research. Undoubtedly, snoring can be a major nuisance to the cosleeper due to its disruptive effect on sleep. Data suggests that snoring may be associated with an increased risk of cardiovascular morbidity [2][3][4].Snoring may also be the symptom of a broad spectrum of obstructive respiratory abnormalities during sleep. This spectrum may range from the upper airway resistance syndrome (UARS) to overt obstructive sleep apnoea syndrome (OSAS). Both UARS and OSAS can be characterized by frequent arousal from sleep causing daytime sleepiness in certain individuals [5,6].The magnitude of this problem is amplified by the high prevalence of snoring in the general population. Various studies estimate a prevalence of 16-89% in the general population [7][8][9]. A recently published review [10] concerning the current knowledge of snoring and its health consequences, has emphasized that much of the uncertainty regarding direct health outcomes of snoring is in part related to the fact that most studies on the prevalence and health outcomes of snoring have not directly measured snoring.To obtain quantitative data on the occurrence and natural history of snoring, a study comparing the direct measurement of snoring in a young college student population and an older population was conducted. Materials and methods Study subjectsThe young population compr...

“…In these matters, the nasal-pharyngoscopy with Müller's maneuver (which assesses the dynamic behavior and the degree of retropalatal and retrolingual collapse during maximum inspiration with both the mouth and he nose occluded) is the assessment method currently being used5. Nonetheless, its usefulness in surgery planning with the goal of correlating its findings with the success expectations of surgical treatment (especially, uvulopalatopharyngoplasty -UPPP) is extremely controversial [6][7][8] . There are some papers, which correlate retropalatal collapse alone with the therapeutic success of UPPP for the treatment of OSAS, and others did not find this correlation 9,10 .…”

The use of nasopharyngoscopy during the application of intrathoracic pressure (Müller maneuver) is frequently employed to establish the site of upper airway obstruction. The Müller maneuver, however, is used when the patient is awake and therefore may not correlate with obstruction occurring during sleep. Aim: to compare the degree of pharyngeal obstruction in the retropalatal and retroglossal regions during the Müller maneuver versus induced sleep using nasopharyngoscopy. Study design: A prospective, case series study. Material and methods: Eight patients (three males, five females), with a mean age of 48.6 +/-9,2 year, underwent nasopharyngoscopy to assess airway anatomy and funciton during the Müller maneuver while awake and during sleep induced by drip infusion of Midazolam. Results: Retropalatal obstruction was similar during the Müller maneuver and sleep (mean + standard deviation = 3.13 +/-0.99 and 2.75 +/-0.46, p= 0.234). Retroglossal obstruction was significantly lower during Müller maneuver compared to sleep (mean + standard deviation 0.63 +/-1.06 and 2.63 +/-1.30, respectively, p= 0.005). Conclusion: The sleep inducing method was safe under the monitored conditions of this study, and detected more retroglossal obstruction than the Müller maneuver.
