A conservative surgical technique is proposed as an alternative to the classical uvulopalatopharyngoplasty (UPPP) for the treatment of obstructive sleep apnea and
snoring
. The resection is strictly intrapalatine, and careful suturing in three planes seems to lead to complete disappearance of the often unbearable postoperative pain. The soft palate is shortened but nonetheless still resembles a normal soft palate. Uvulopalatopharyngoplasty (UPPP) was described by Ikematsu in 1952. This method has taken on a new lease of life in recent years. Its efficacy is generally accepted, and its use, especially in cases of obstructive sleep apnea syndrome, is the only treatment of the palatal velum at present practiced. In addition to aesthetic problems, this method generally gives rise to complications in the shape of temporary--but sometimes considerable--pain, nasal regurgitation, and a nasal voice. In a small percentage of patients, some of these disorders may prove irreversible. In my series of eight patients, five were obese and presented with
hypertension
. Three of them also were suffering from obstructive sleep apnea syndrome. The three others were ordinary snorers who caused considerable inconvenience to sleeping partners.

In order to evaluate possible correlations between blood pressure levels and sleep quality, 7,901 workers of both sexes living in Paris area have been the subject of a survey during their annual examination performed by workside physicians. The enquiry included questions related to sleep quantity and quality, sleeping pills consumption, awakenings, nightmares,
snoring
, way of life and working conditions. The information concerning these parameters was available for 7,542 people. Among them, 6,551 (86.9%) did not suffer from
high blood pressure
(
HBP
) (blood pressure less than 160/95 mmHg), 618 (8.2%) presented a
high blood pressure
but were not treated, 371 (4.9%) received a treatment against
HBP
. The average sleep duration is about 7.4 h (S.D. = 1.0) for men and about 7.6 h (S.D. = 1.0) for women (less than 0.001). It is significatively and negatively correlated with the systolic blood pressure level (SBP) (less than 0.001) and the diastolic blood pressure level (DBP) (less than 0.001). The frequency of patients complaining of nightly awakening and of
snoring
significatively increase with SBP (p less than 0.05) and DBP (p less than 0.001). The observed association between DBP (but not SBP) and sleep duration and nightly awakening remains significant in multivariate analysis including age, sex, tobacco smoking, alcohol and coffee consumption, use of sleeping pills and hypotensive treatment, as well as the negative correlation between SBP and nightmare frequency. The correlation between SBP or SBP and
snoring
was no more significant. In conclusion, a significant correlation has been found between the blood pressure levels and the sleep quality whose clinical consequences remain to be explored.(ABSTRACT TRUNCATED AT 250 WORDS)

Because sleep apnoea syndrome is often associated with arterial
hypertension
, it has been suggested that sleep apnoea might be responsible for
hypertension
. This hypothesis is mainly based on epidemiological studies showing a statistically significant association between
snoring
and arterial
hypertension
; this association remains true even after data correction to take into account the increased frequency of
snoring
with age and overweight. However, this statistical link is no evidence of a cause-effect relationship, and the mechanism through which sleep apnoea syndrome could produce arterial
hypertension
remains unknown. Yet treatment of sleep apnoea syndrome seems to improve arterial
hypertension
, and this alone would justify a search for sleep apnoea syndrome in all patients presenting with arterial
hypertension
.

To evaluate cardiac structure and function as well as blood pressure in the obstructive sleep apnoea syndrome (OSAS), we investigated 61 male patients and 61 male controls with M-mode and two-dimensional echocardiography. All patients had a history of habitual
snoring
and a diagnosed light to severe OSAS by previous investigations of nocturnal oxygen saturation status. No subject in the control group had a history of OSAS or
hypertension
. Body weight was higher in the OSAS patients than in the controls (P less than 0.001). Fifty per cent (31 out of 61) of the OSAS patients had
systemic hypertension
; 17 of these 31 were on pharmacological antihypertensive treatment. Neither the systolic nor the diastolic blood pressures were found to correlate to the severity of the OSAS (desaturation index). The heart rate was higher at rest in the OSAS patients with or without
systemic hypertension
compared to the controls with or without a blood pressure level above 165/95 mmHg (P less than 0.05 and P less than 0.01, respectively). Left ventricular (LV) internal dimensions as assessed by echocardiography did not differ between the two groups, while the interventricular septum and the LV posterior wall were thicker in the OSAS group. Thus, the LV mass and the LV mass index were significantly higher among the OSAS patients (P less than 0.001 and P less than 0.001). The LV mass index was approximately 15% higher among the 30 normotensive OSAS patients with no history of cardiac disease compared with the normotensive controls (P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Normal sleep provides a period of physiologically reduced workload for the cardiovascular system for almost one third of the human life span.
Snoring
, the most common disorder of sleep, heralds the presence of an unstable upper airway and alerts perceptive clinicians to the possibility of OSA. Epidemiologic evidence has implicated
snoring
as an independent risk factor for the development of
hypertension
, ischemic heart disease, and cerebral infarction. However, many investigators would attribute these adverse cardiovascular effects to the substantial prevalence of OSA in habitual snorers. The detrimental effects of OSA on hemodynamics and cardiac rhythm have been well documented, and recent data have linked OSA with increased cardiovascular mortality. Worsening hypoxemia during sleep likely contributes to the nocturnal mortality observed in patients with severe COPD. Effective treatment to prevent nocturnal hypoxemia is available for OSA and COPD, with current evidence supporting beneficial effects on survival.

A 39-year old Chinese man presented with an acute onset of severe headache, accelerated
hypertension
and subsequently an unexpected extensive right occipital haemorrhage. These were found to be related to a sleep apnoea syndrome which had been unrecognized for many years despite its typical symptoms of loud
snoring
and excessive daytime sleepiness. Weight reduction led to significant clinical but not polysomnographic improvement of the sleep apnoea syndrome.

Arterial
hypertension
was found in 78 of 224 consecutive patients operated for nasal polyposis. An exacerbated degree of
hypertension
was significant in groups aged above 50 years. In total, 46% of patients whose nasal polyposis was of a duration of more than 10 years suffered from
hypertension
. Fifty of 78 patients developed
hypertension
after nasal polyposis was established and the mean duration time from polyposis to
hypertension
was 11.1 years.
Hypertension
was established in 50% of patients suffering from the triad asthma, intolerance to acetylsalicylic acid and nasal polyposis. In analogy with knowledge that sleep apnoea and
snoring
are aetiological factors for arterial
hypertension
, we propose that long-standing nasal obstruction by nasal polyposis be a risk factor for arterial
hypertension
.

The diagnosis of obstructive sleep apnea is frequently made by taking a meticulous history coupled with a high index of suspicion.
Snoring
and hypersomnolence are clinical features common to individuals with sleep apnea. Since
snoring
is said to be a "disease of listeners," it is not uncommon that bed partners reported an increased incidence of depression and marital displeasure. It is for this reason that the spouse or bed partner should be interviewed, since the patient may not be aware of any sleeping problems. Physicians should also be alert to complaints of excessive daytime somnolence, because studies have shown that patients with obstructive sleep apnea are at increased risk for automobile crashes. It has been estimated that approx 58,000 motor vehicle accidents involving people with sleep apnea will occur in the US each yr. By proper diagnosis and treatment, the physician is in a unique position to prevent at least some of the automobile accidents that result from falling asleep while driving. Polysomnography is the only definitive way to obtain a diagnosis of sleep apnea. This allows the physician not only to diagnosis the disorder, but also helps in the evaluation of the severity of the syndrome and selection of therapy. An ENT evaluation is also important in ruling out anatomic disorders that can cause upper airway obstruction. Certain factors, such as alcohol and sedative ingestion, may aggravate the condition in a person predisposed to sleep apnea, and subtle changes, such as unexplained
hypertension
, polycythemia, and cor pulmonale, should lead one to investigate the possibility of sleep apnea as the etiology.

Snoring
was investigated in a survey of respiratory disease in Hispanic-Americans of a New Mexico community. A population-based sample of 1222 adults was studied with questionnaires and measurements of height, weight, and blood pressure. The age-adjusted prevalence of regular loud
snoring
was 27.8% in men and 15.3% in women.
Snoring
prevalence increased with age and obesity in both men and women. Cigarette smoking was also associated with
snoring
, but chronic obstructive lung disease and alcohol consumption were not. Snorers more frequently had
hypertension
, ischemic heart disease, and excessive daytime sleepiness. In contrast to other studies, after adjustment for confounding factors, there was no effect of
snoring
on
hypertension
(odds ratio, 1.0; 95% confidence interval, 0.7 to 1.5), but an effect on myocardial infarction was still demonstrable (odds ratio, 1.8; 95% confidence interval, 0.9 to 3.6). The association of
snoring
with sleepiness suggests that respiratory disturbance of sleep related to upper airway obstruction, such as sleep apnea, occurs more frequently in snorers in this population.

We compared self- and spouse reports of
snoring
and other symptoms of sleep apnea syndrome ascertained from married couples in a community-based survey. Agreement between the two types of report varied between 70-98%, but was modest (kappa = -0.01-0.52) when adjusted for chance. For men, spouse reports yielded higher prevalence rates for
snoring
and for four other symptoms. For women, estimates of symptom prevalence were consistently lower by spouse report than by self-report. In multivariate analyses, the effect on
snoring
of gender and obesity increased and of age decreased when spouse reports were compared to self-reports.
Snoring
, according to spouse reports, was a significant risk factor for ischemic heart disease, but
snoring
according to self-reports showed a smaller effect and was not statistically significant.
Snoring
was not associated with
hypertension
when defined by either self- or spouse report. These observations suggest that questionnaire data of
snoring
and other symptoms of sleep apnea syndrome may be misclassified in part, and that such misclassification can affect estimates of prevalence and effects.
