RMM and PNIF provide valuable information to support clinical decision making. However, with both methods, approximately 25% of symptomatic patients with functionally relevant nasal structural deformity were not detected. A negative test outcome of RMM or PNIF does not exclude a functionally relevant nasal stenosis.
The most frequent complications of septoplasty are deformities, infections, and perforations. The effects of each of these complications, however, can be very different. Dislocations and deformities of the septum may result not only in an impaired airway but also in visible deformities of the entire nasal base and dorsum. A patient who underwent septoplasty can be "stigmatized." Infections may lead not only to septal abscess but also to endocranial complications such as meningitis or septicemia with endocarditis. Permanent perforations of the nasal septum can result in significant symptoms if they are located in the anterior part of the nose. Surgical closure is the treatment of choice, with a high success rate if the patients are selected properly. Besides these three major types of complications there are many others, from smell disturbances to blindness. Causes, prevention, and correction of selected complications are presented and data of the recent literature reported.
There are no significant differences in the bacteriologic features of ethmoidal biopsy specimens between CRSNP+, CRSNP-, and control patients. Therefore, a bacteriologic pathogenesis of the polyps in CRSNP+ patients seems unlikely. The general use of antibiotics in patients with CRS appears questionable. Investigation of nasal lavage samples is not suitable for predicting the bacteriologic features of inflamed sinuses of patients with CRS.
A significant T(H)2 skew in CRSNP(+) could be confirmed on the cellular level. It was driven by low myeloid dendritic cell numbers. The T(H)2 skew did not correlate with S. aureus detection. The data support the concept that CRSNP(+) and CRSNP(-) are pathophysiologically distinct.
We could not observe a higher prevalence of S. aureus in CRS patients with or without nasal polyps than in controls. We could not substantiate that S. aureus intensifies the T(H2) shift in CRSNP(+) patients. Staphylococcus aureus small colony variants were not detected in any sample.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
