Before the invention of CPAP therapy, the only effective surgical treatment for obstructive sleep apnea syndrome was tracheotomy. Now, surgical approaches mainly focus on two anatomical sites. Each procedure influences either the retropalatal or retrolingual portion of the pharynx. They might be applied individually, synchronously with other procedures, or sequentially with other therapeutic devices. Common methods of velar surgery include uvulopalatopharyngoplasty (UPPP), Laser-assisted uvuloplasty (LAUP), radiofrequency or uvulaflap. These techniques are indicated mainly in patients with mild OSAS. Other procedures focus on the posterior airway space (PAS), including operations that reduce the volume of the tongue or base of tongue. In selected patients, an enlargement of the retrolingual airway is gained by osteosynthetic techniques. Improvement of the nasal airway passage is gained by performing a septoplasty and/or conchotomy. In this paper, the different methods and their indications for surgical therapy will be explained and the results are summarized.
There is undoubtedly a need for a safe disinfection method of optical instruments used by ENT specialists. So far, a standard method that sufficiently covers the risk of infection for patients and medical staff alike while serving the need of practicability in daily routine has not been established. Therefore, in the ENT departments of the hospitals of Mannheim, Kaiserslautern, and Tübingen, studies on the disinfection of rigid optical instruments without working channel were performed between February 1999 and May 1999. Instruments were wiped either with an aldehyde or alcohol (ethanol 80%) and germs were detected by quantitative swab cultures. As discussed in the article, disinfection with ethanol proved to be at least equally efficient if not better than disinfection with aldehyde. Therefore, it fully serves the requirements of a safe method for disinfecting optical instruments without working channels.
Oral appliances are used to treat snoring and sleep apnea. Yet, their success cannot be predicted without a therapeutical trial. This uncertainty and the high prices of the appliances are the reasons for their limited use. We tested a cheap, custom fit mandibular advancement device (SnorBan) for the treatment of sleep disordered breathing in order to assess its efficacy. 39 consecutive patients (51.1 +/- 9.2 years, BMI = 27.4 +/- 4.5 kg/m2) with different degrees of sleep disordered breathing (AHI = 16.6/h +/- 15.6/h) received the device after a thorough clinical examination. After getting used to the device a second polysomnography was performed. The AHI improved significantly from 16.6/h to 8.2/h (P < 0.01) in the whole group. The only patient who became worse could not get used to the device. Time with snoring dropped significantly from 16.3% to 6.6%, 59.1% of the sleep apnea patients were successfully treated as their RDI dropped below 10/h. The sleep efficiency remained unchanged. Slow wave sleep and REM-sleep increased significantly from 12% to 16% (P < 0.05). The overall compliance was 75%. The custom fit mandibular advancement device Snorban is a cheap and effective treatment for a number of patients with snoring and sleep apnea. The oral appliance is proven to be a useful and simple, non-surgical treatment option. Polysomnographic follow-up is mandatory as breathing may worsen with the device while asleep.
