One hundred and fifty-five patients with complaints indicating acute sinusitis were examined and their symptoms and signs registered. The final diagnosis--maxillary sinus empyema versus not empyema--was established by means of antral aspiration. A computer-based analysis of clinical data demonstrated the significance of the clinical examination. Local symptoms such as pain and purulent rhinorrhea with unilateral predominance were particularly guiding, even in bilateral cases, while nasal obstruction, tenderness during percussion, and affected general condition were not. With an overall reliability of about 85%, appropriate therapy can be suggested based on the clinical findings alone.

Patients with clinical features of sleep apnea syndrome (SAS) and self-reported sleep spells at the wheel do poorly in simulated monotonous driving. To evaluate whether drivers with defined symptoms of SAS (heavy snoring, sleep disturbances and daytime sleepiness) compensate in real traffic by careful driving or not, the rate of car accidents over a 5-year period was investigated. A questionnaire was addressed to 140 patients with and 142 controls without symptoms associated to SAS. Seventy-three of the patients had a complete triad of SAS-associated symptoms. Fifty-two percent of these patients reported habitual sleep spells at the wheel, as opposed to less than one percent by the controls. The ratio of drivers being involved in one or more combined-car accident was similar for patients and control drivers, but for single-car accidents the ratio was about 7 times higher for patients with a complete triad of symptoms of SAS compared to controls (p < 0.001). When corrected for mileage driven, the total number of single-car accidents was almost 12 times higher among patients with sleep spells whilst driving, compared to controls (p < 0.001). It is concluded that drivers with the clinical features of SAS are at increased risk especially for single-car accidents and that the risk seems to vary with the severity of symptoms.

Velopharyngeal sonorous snoring is best treated with uvulopalatopharyngoplasty (UPPP). To reduce surgical risks and minimize the morbidity, a simplified carbon dioxide laser uvulopalatoplasty (LUPP) was performed under local anesthesia. Among a total of 146 patients who had a LUPP performed, there was no significant bleeding or postoperative episodes of asphyxia. The procedure was well tolerated even by those patients with strong vomiting reflexes. The operation time was halved, as was the convalescence. Two patients (1.4%) developed scarring with nasal obstruction, but the impact of factors other than the laser approach itself seemed to be the cause. By scored questionnaires the effect on snoring, family complaints, and daytime somnolence was evaluated in two comparable random groups of patients. Sixty-three patients had LUPP procedures, and 37 had UPPP. The short-term results showed that about 90% of the patients considered themselves essentially improved as regarded snoring and that most patients felt more alert, irrespective of the surgical method used.

Patients with rhonchopathy, which includes obstructive sleep apnea syndrome (OSAS), who report sleepy spells at the wheel do poorly on simulated monotonous driving tests and have a twofold to threefold increase in traffic accidents. To assess whether drivers with rhonchopathy (heavy snoring, sleep disturbances, and daytime sleepiness) cause fewer automobile accidents after uvulopalatopharyngoplasty (UPPP), the car accident rate for the first 5 years after surgery was compared to the rate of the 5 years immediately before the operation. Data were collected by means of a self-report questionnaire. Fifty-six patients with rhonchopathy were compared to 142 controls without rhonchopathy who had been subjected to nasal surgery. The response rates were 96% and 94%, respectively. The reported habitual sleepiness while driving had disappeared in 87% (P < .001) of drivers who had the problem preoperatively. The accident risk reduction (corrected for mileage) in patients was almost four times greater than the reduction in controls (P < .001) after surgery. The relative rate of patients involved in any single-car accident fell by 77% (P < .05), and the relative rate of single-car accidents fell by 83% (P < .001). It is concluded that drivers with rhonchopathy have an increased risk for car accidents, especially single-car accidents, but that this risk returns to normal after UPPP.

By antral aspiration, 200 sinus secretions were obtained from the same number of adult patients with maxillary sinusitis. The bacteriological findings were related to the character of the secretions as well as to the duration of symptoms, previous antibacterial treatment and possible dental genesis. Pathogens were isolated in 87% of 54 patients with untreated acute sinus empyema, Streptococcus pneumoniae being the most prevalent (57%). In 47 cases of treatment failure Haemophilus influenzae predominated and was found in 60% of the purulent secretions. In all, 11% of the 47 cases showed growth of beta-lactamase-producing H. influenzae, corresponding to 18% of all H. influenzae in this group. Staphylococcus aureus and anaerobic bacteria were infrequent findings except in purulent sinus secretion from patients with a long history. In contrast to patients with sinus empyema, no pathogens were found in the majority of 37 patients with non-purulent sinusitis.
