The Drainage System of the Paranasal Sinuses: A Review with Possible Implications for Balloon Catheter Dilation
2011
Background Intersinus connections and accessory ostia of the maxillary sinus are well known to rhinologic surgeons but are less known for the remaining paranasal sinuses. Probing and dilatation of the natural ostia of diseased sinuses is being popularized currently by the clinical value of balloon catheter dilation (BCD). Although short-term high success rates with treatment of the dilated ostia/duct have been reported with this technique, the potential impact of fractures of adjacent bony septae on accessory sinus ostia, on mucosally lined surfaces, and on intersinus drainage pathways still has not been considered. The aim of this study was to review the literature on accessory sinus ostia…
Deguna vārsta kustīguma kvantitatīvs novērtējums
2018
Pamatojums: Deguna vārsts ir visšaurākais reģions visos augšējos elpceļos. Tā ir kustīgā deguna daļa, kas tiek uzskatīta par STARLING-rezistoru. Lai paplašinātu vai stabilizētu deguna vārstu, ir publicētas dažādas palīgierīces un metodes, taču indikācijas to izmantošanai ir balstītas vien uz ķirurgu personīgo pieredzi. Mērķis: Veikt objektīvu deguna vārsta lomas novērtējumu. Materiāli un metodes: Pētījumā tika iekļauti 30 brīvprātīgie, kuriem ar elastīgu tērauda elementu, fiksētu pie galvas lentes un aprīkotu ar deformācijas sensoru (strain gauge), tika precīzi izmērīta deguna laterālās sienas novirze tās dziļākajā punktā elpošanas laikā. Novirzes kalibrācija tika veikta ar speciālām kalibr…
An Assessment of Radiologic Discrepancies in Patients with Paranasal Sinus Disease
1992
The importance of computerized tomographic (CT) imaging of the paranasal sinuses in patients with chronic or recurring sinusitis is well documented. Nevertheless, the accuracy and reliability of this examination is not absolute. In this study of 80 cases, a considerable percentage of CT scans (57.5%) failed to detail accurately the extent of pathology in the sinus cavities. In 39 cases the extent of disease was underestimated using CT, and in seven cases it was overestimated. Discrepancies in pathology were encountered most commonly in the posterior ethmoid sinus. In our opinion, the primary role of CT in the assessment of patients with paranasal sinus disease is to detail precisely the co…
