[Snoring/sleep apnea--surgically curable]

[Guideline: Treatment of obstructive sleep apnea in adults]

The current guideline discusses conservative and surgical therapy of obstructive sleep apnea (OSA) in adults from the perspective of the ear, nose and throat specialist. The revised guideline was commissioned by the German Society of Ear-Nose-Throat, Head-Neck Surgery (DG HNO KHC) and compiled by the DG HNO KHC's Working Group on Sleep Medicine. The guideline was based on a formal consensus procedure according to the guidelines set out by the German Association of Scientific Medical Societies (AWMF) in the form of a"S2e guideline". Research of the literature available on the subject up to and including December 2008 forms the basis for the recommendations. Evaluation of the publications found was made according to the recommendations of the Oxford Centre for Evidence-Based Medicine (OCEBM). This yielded a recommendation grade, whereby grade A represents highly evidence-based studies and grade D those with a low evidence base.

[Anterior spondylosis of the cervical spine causing dyspnea and sleep disturbance]

BACKGROUND

Cervical osteochondrosis is a rare differential diagnosis leading to dysphagia, inspiratory stridor and obstructive sleep apnea syndrome (OSAS).

PATIENTS AND METHODS

We report six cases of patients with episodes of neck pain (n=6), pain reflected to the arm (n=1), sleep apnea (n=5), inspiratory stridor (n=3) and/or unclear dysphagia (n=6), who presented between 2000 and 2003 at the Römerwallklinik Mainz and the university hospitals of Mainz and Cologne. None of these patients had symptoms of spinal or radicular compression. All underwent otorhinolaryngological and radiological examination followed by excision of anterior spondylophytes and intervertebral fusion. One patient required immediate tracheotomy due to perforation of the pharyngeal wall associated with severe supraglottic swelling.

RESULTS

All patients were free of inspiratory stridor postoperatively. Symptoms of dysphagia disappeared in four patients and were reduced in two. Three of five patients were free of apnea. OSAS had improved in two. Neck pain was eliminated in four cases and markedly improved in two cases.

CONCLUSIONS

In case of symptoms of pharyngeal compression and OSAS, a vertebragenic cause should be considered.

One stage multilevel surgery (uvulopalatopharyngoplasty, hyoid suspension, radiofrequent ablation of the tongue base with/without genioglossus advancement), in obstructive sleep apnea syndrome

We evaluated the surgical results of a one tempo multilevel surgical approach of the upper airway to treat patients with obstructive sleep apnea syndrome (OSAS) in a prospective case series. Twenty-two patients with OSAS and obstruction at both palatinal and tongue base level, as assessed by sleep endoscopy, underwent UPPP, RFTB, HS with or without GA in one operative session. The mean apnea hypopnea index (AHI) decreased from 48.7 (range 17.4-100.9) to 28.8 (P < 0.0001). The success rate (AHI <20 and >50% reduction in AHI) was 45%, the response rate (reduction in AHI of 20-50%) was 27%. The overall response rate was 72%. The success rates of patients with an AHI <55 and >55 were 56 and 0%, respectively. The overall response rate of patients with an AHI <55 was 78% and >55 was 50%. Improvement of desaturation index was significant from 31.9 to 17.6 (P < 0.0001). Visual analogue scales for snoring and hypersomnolence and the Epworth Sleepiness Scores showed significant improvements too (all P < 0.0001). There was no difference in objective and subjective outcomes between the group with and without GA. This study demonstrates that one stage multilevel surgery, in which genioglossus advancement is not of additional value, is a valuable addition to the therapeutic armentarium and can be considered a viable alternative, objective as well as subjective, to NCPAP or as primary treatment in well selected patients with moderate to severe OSAS with an AHI <55.

[Subjective outcome after multi-level surgery in sleep-disordered breathing]

INTRODUCTION

Previous results showed the high effectiveness of our multi-level surgery concept based on the modified hyoid suspension for obstructive sleep apnea (OSA). This study was aimed at evaluating the discomforts and side-effects of this surgical concept.

METHODS

Between November 2001 and June 2004, 102 patients with OSA and/or with laryngeal stenosis, who were all treated with a hyoid suspension in combination with surgery at the base of tongue, the soft palate or the nose, were included in the study. A questionnaire on discomfort and snoring was given to the patients. They were asked to answer the questions at the earliest 1 month after surgery. A reduction in snoring to a level which was tolerated by the bed-partner was regarded as success.

RESULTS

Half of the patients needed analgesics until the 14th day after surgery, complained dysphagia until day 20 and had problems with their speech until day 30. However, 84% indicated that they would undergo surgery again; 94% reported a successful reduction in their snoring.

CONCLUSION

Nearly all of the patients tolerated the discomforts and side-effects of our multi-level surgical concept. In combination with a reduction in snoring in 94% of all cases, this surgical concept was considered favorably by the patients.
