[Surgical treatment for obstructive sleep disordered breathing].

The obstructive sleep apnea syndrome is a chronic condition characterized by repeated nocturnal pharyngeal collapse leading to poor-quality sleep and an increased risk of cardiovascular episodes. The classic management by continuous positive-pressure ventilation has its limitations and is not always well tolerated. The treatment alternative comprising an orthotic device is effective in 2/3 of cases, despite the dental limitations and risks inherent in long-term usage.

Bilateral hypoglossal nerve stimulation for treatment of adult obstructive sleep apnoea.

Background And Aim: Hypoglossal nerve stimulation (HNS) decreases obstructive sleep apnoea (OSA) severity genioglossus muscle activation and decreased upper airway collapsibility. This study assessed the safety and effectiveness at 6 months post-implantation of a novel device delivering bilateral HNS a small implanted electrode activated by a unit worn externally, to treat OSA: the Genio™ system.

Methods: This prospective, open-label, non-randomised, single-arm treatment study was conducted at eight centres in three countries (Australia, France and the UK).

Materials And Methods: Fifteen consecutive apneic patients displaying a wide variety of morphological types, mean age 42 years (20-59), a BMI of 26.60 kg/m(2) (22-29), a mean initial Apnea Hypopnea Index (AHI) of 50.

Forces created by mandibular advancement devices in OSAS patients: a pilot study during sleep.

Background: The aim of this study was to measure forces created by progressive mandibular advancement with an oral device, during natural sleep, in a sample of adult patients with obstructive sleep apnea syndrome (OSAS).

Methods: A pressure transducer system was placed on the acrylic arms of a two-piece oral appliance (Herbst type) used by nine moderate to severe OSAS patients, in addition to all captors routinely used for polysomnography. Strains on the left and right sides were collected, during stable sleep stages without arousal, for each step of 1 mm advancement.

Treatment of the obstructive sleep apnea syndrome in adults by mandibular advancement device: the state of the art.

The obstructive sleep apnea syndrome (OSAS) constitutes a non-negligible risk which requires management by specialists of the upper airways. When OSAS is diagnosed, it needs to be treated and different resources are listed. Different forms of treatment can be envisaged: positive pressure ventilation (VCPP), mandibular advancement devices (MAD), and surgery (soft and hard tissues).

[The set-up of obstructive sleep apnea treatment].

The therapeutic strategy of obstructive sleep apnea syndrome (OSAS) is dependent on the illness severity, which is influenced by several factors as the presence of comorbidities (particularly cardiovascular comorbidities), the importance of diurnal drowsiness and the number of abnormal respiratory events. Whereas the treatment is most often palliative and uncomfortable, its success is closely dependent on its compliance. The way of starting the treatment of OSAS is therefore an essential topic, which will condition its long-term acceptance.

Titrated mandibular advancement versus positive airway pressure for sleep apnoea.

The aim of this study was to compare mandibular advancement device (MAd) therapy and continuous positive airway pressure (CPAP) for obstructive sleep apnoea/hypopnoea syndrome (OSAHS) after one-night polysomnographic (PSG) titration of both treatments. 59 OSAHS patients (apnoea/hypopnoea index (AHI): 34+/-13 events x h(-1); Epworth scale: 10.6+/-4.

Effects of mandibular advancement on upper airway dynamics in awake normal subjects: a pilot study with phrenic nerve stimulation.

Background: Mandibular advancement (MA) can be an alternative to continuous positive airway pressure (CPAP) in the treatment of obstructive sleep apnea syndrome. This study was designed to describe its effects on upper airway mechanics.

Methods: Six awake healthy subjects (four men, 31+/-8 years, body mass index (BMI) 25+/-2kg/m2) were studied supine.

Mandibular advancement titration for obstructive sleep apnea: optimization of the procedure by combining clinical and oximetric parameters.

Background: Oral appliances (OAs) have been used for the treatment of obstructive sleep apnea syndrome (OSAS), with different degrees of effectiveness having been shown in previous studies. But, in the absence of a consensual recommendation, the method of the determination of effective mandibular advancement varies from one study to another.

Study Objective: We prospectively evaluated an OA titration protocol based on a combined analysis of symptomatic benefit and oximetric recording to guide the progressive mandibular advancement.

Vertebrobasilar occlusive disorders presenting as sudden sensorineural hearing loss.

Background: Isolated sudden sensorineural hearing loss (SSHL) has been rarely related to vertebrobasilar occlusive disorders (VBOD). This is an important issue for both neurologists and otolaryngologists, since the management and prognosis of this type of hearing loss widely differs from that of hearing loss from other causes.

Objectives: To describe the clinical characteristics and report the incidence of SSHL related to VBOD.

Radiofrequency soft palate procedure in snoring: influence of energy delivered.

Objective: We conducted a retrospective study to evaluate the influence of amount of energy delivered during radiofrequency procedure for soft palate reduction in snoring, to improve the cure rate.

Methods: Consecutive patients with chronic disruptive snoring presenting to our department were successively treated in an outpatient procedure. A visual analog scale was used to assess the severity of snoring by the bed partner and the pain by the patient, before treatment and after each treatment session.

Clinical impact of somatostatin receptor scintigraphy in the management of paragangliomas of the head and neck.

Unlabelled: Paragangliomas are neuroendocrine tumors expressing somatostatinergic receptors and, thus, may be imaged by somatostatin receptor scintigraphy (SRS). The purpose of the study was to assess the contribution of SRS in the management of paraganglioma of the head and neck.

Methods: (111)In-Pentetreotide (148 MBq) was intravenously administered to 3 groups of patients.
