In 22 subjects, the FSP strategy could be implemented (FSP group), in 10 patients not (high-definition continuous interleaved sampling, HDCIS, group). Subjects were tested with the Tempo+ (CIS+) just before switch-over and after 12 months of OPUS 2 (FSP/HDCIS) use. Performance with FSP/HDCIS was tested at switch-over, and after 1, 3, 6 and 12 months. A sentence-in-noise test and a Speech Spatial and Qualities of Hearing Scale (SSQ) questionnaire were assessed at each test interval.Results: In the FSP group, the speech reception threshold shows a deterioration of 3.3 dB (n.s.) at the acute switch-over interval, but a significant improvement over time (p < 0.001) with a final benefit of 6.5 dB after 12 months of FSP use. A significant improvement over time can also be seen on the spatial subscore of the SSQ questionnaire (p = 0.009). No significant differences could be seen in the HDCIS group.Conclusion: The results show that by enhancing fine structure coding in the lower frequencies, as implemented in the FSP coding strategy, speech perception in noise can be enhanced.","PeriodicalId":520736,"journal":{"name":"ORL; journal for oto-rhino-laryngology and its related specialties","volume":" ","pages":"305-11"},"PeriodicalIF":1.3,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000319748","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40074121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This surgical technique has 5 important steps, including exposing the choana, enlarging the maxillary sinus ostium, opening the sphenoid sinus and posterior ethmoid sinus anteriorly to posteriorly, resecting the ethmoid sinus posteriorly to anteriorly, and opening the frontal sinus posteriorly to anteriorly. The choana, maxillary sinus ostium, middle turbinate remnant, and the roof and lateral wall of the sphenoid sinus are 4 stable anatomic reference points.Results: Twelve months postoperatively, the mean SNOT-22 score had improved by 18.48 and 100 (88.50%) patients had an improvement in nasal obstruction; thick nasal discharge, loss of smell or taste, and facial pain/pressure improvements were noted in 102 (90.27%), 64 (56.64%) and 76 (67.26%) patients, respectively. Postoperative endoscopic evaluation after 12 months indicated that 29 (25.66%), 12 (10.62%), 5 (4.42%), 6 (5.31%), and 2 (1.77%) patients had mucosal edema, nasal discharge, synechiae, polyps, and crusting, respectively.

Fluoroquinolones are the only enterally administered antibiotics with efficacy against P. aeruginosa, but their frequent empiric use in the community raises concern for a rise in resistance.Objective: It was the aim of this study to determine the prevalence of fluoroquinolone-resistant P. aeruginosa in a tertiary rhinology practice.Methods: All bacterial sinus culture results from the outpatient otolaryngology clinic that yielded P. aeruginosa over a 5-year period (2002-2007) were reviewed along with the medical records of a randomly selected subset of patients.Results: In total, 689 culture results of 324 patients were examined. Nearly all patients had a history of endoscopic sinus surgery. Of all P. aeruginosa cultured, 13% were resistant to levofloxacin and 5% were intermediately sensitive, while 5% were resistant to ciprofloxacin and 7% intermediately sensitive. Of the 324 patients in the study, 19 and 15% had a history of a P. aeruginosa culture resistant to levofloxacin or ciprofloxacin, respectively. Mucoid strains of P. aeruginosa were significantly more likely to be fluoroquinolone resistant. No patient comorbidities were associated with a higher rate of resistance. The prevalence of resistant cultures remained stable over the 5-year study period.Conclusions: P. aeruginosa is cultured primarily in patients with previous sinus surgery. Nearly 20% of isolates are resistant to fluoroquinolones. Resistance to levofloxacin is more common than resistance to ciprofloxacin. This study supports the use of culture-directed therapy in the management of the postfunctional endoscopic sinus surgery patient and the avoidance of empiric use of fluoroquinolones.","PeriodicalId":520736,"journal":{"name":"ORL; journal for oto-rhino-laryngology and its related specialties","volume":" ","pages":"263-7"},"PeriodicalIF":1.3,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000242428","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40050336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In many cases an additional hampering of the respiratory function of the nose is seen and causes pathological nasal airflow patterns. For the functional outcome of aesthetic-surgery of the nose, knowledge of nasal flow is essential. In the medical literature there are some discrepancies between the relationship of nasal shape and nasal flow. We investigated typical airflow patterns in different abnormalities of the external nose.Methods: We performed fluid dynamic experiments on exact, anatomical nasal models and functional nasal models (so-called modified Mink boxes). We investigated the inspiratory flow pattern in nose-models with typical variations of the shape of the external nose.Results and conclusions: There were typical airflow patterns for every external nasal abnormalities. The normal nose shows a disturbance of the streamlines over the entire nasal cavum. Under physiological flow velocities we find laminar and turbulent flow. The pathological variations of the nasal shape show mostly different airflow patterns and characteristics. The main reason for that is a deformed or anatomically false configurated inflow area (vestibulum, isthmus and anterior cavum). During rhinoplasty the reconstruction of the nasal inflow area has to be taken into account.","PeriodicalId":520736,"journal":{"name":"ORL; journal for oto-rhino-laryngology and its related specialties","volume":" ","pages":"154-9"},"PeriodicalIF":1.3,"publicationDate":"2005-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000086017","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41017126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Affected patients suffer from a dry nose, crusts as well as recurrent epistaxis and sometimes an inspiratory whistle. The aim of this study was to investigate the underlying flow dynamic mechanisms.Methods: The physical flow effects of such pathologies were examined in functional nose models (box models) and anatomically exact models of the nose. Therefore, septal perforations of different sizes and localisations were studied in straight and deviated nasal septa.Results and conclusions: It could be seen that the localisation of the perforation has no impact on the flow pattern. In large septal perforations, the air jet collides with the posterior edge of the perforation and disintegrates turbulently. Since airflow is physiologically turbulent in the posterior part of the nose, posterior perforations do not cause clinical complaints. The inspiratory whistling sound during respiration is based on the principle of a lip whistle. Large perforations do not cause a whistling sound. The necessary high flow velocity needed in large perforations is usually not achievable.","PeriodicalId":520736,"journal":{"name":"ORL; journal for oto-rhino-laryngology and its related specialties","volume":" ","pages":"142-7"},"PeriodicalIF":1.3,"publicationDate":"2005-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000085958","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41017124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
