Background:Multidetector computed tomography (MDCT) images for rhinosinusitis may have a risk of radiation hazards. Reduction in radiation dose may lead to a compromise in quality of MDCT images and have chances of postoperative complications.Objective:The aim of the study was to test the applicability of low-dose MDCT protocols for decision-making of sinus surgeries of patients with uncontrolled chronic rhinosinusitis.Design:Randomized, double-blind (patients and evaluators blind), controlled, trial.Setting:People's Hospital of Guanghan, China.Patients:A total of 288 patients with clinically confirmed uncontrolled chronic rhinosinusitis were subjected to randomization (1:1 ratio).Interventions:Patients were subjected to low-dose preoperative protocols of MDCT (n = 144; ldMDCT group) or standard-dose preoperative protocols of MDCT (n = 144; sdMDCT group).Outcome measures:Image analysis was performed by the workstation. Lund-Mackay score, modified Lund-Mackay score, estimated radiation exposure, and surgical complications were evaluated for each patient. The χ2 independent test or 2-tailed paired t test were performed for statistical analysis.Results:The preoperative MDCT images for standard-dose protocol had better quality than low-dose protocol (P < .001, q = 4.57). The area of images that give confidence for sinus surgery at one time was higher for standard-dose MDCT protocol technique than low-dose MDCT protocol method. Patients of ldMDCT group with large growth of nasal polyps (P = .03, q = 5.35) and complete opacification of sinuses (P = .03, q = 7.94) had complications after sinus surgeries. Either low-dose or standard-dose MDCT protocol was performed, the experience of otolaryngologist had decreased complication after surgeries.Conclusion:Preoperative low-dose MDCT should be used for diagnosis of uncontrolled chronic rhinosinusitis for decision making of sinus surgeries.Level of Evidence:III.Trial registration:researchregistry4264 dated 1 March 2016 (www.researchregistry.com).

“…Being the more time-consuming subtests, developing a self-administered procedure for odor discrimination and threshold testing seems valuable for clinicians and research purposes. Lately, olfactory threshold can be measured by computerized devices in a self-administered manner (Jiang and Liang 2015). Costs of these devices however may exceed various research or clinic budgets.…”

Introduction Olfactory testing helps in diagnosing olfactory dysfunction (OD). The Sniffin' Sticks odor test kit is widely used for research and can be reused and summed scores of threshold (T), discrimination (D), and identification (I) allow comparison to normative data. Testing can be time consuming and odor pens have to be presented by an examiner. The aim of this study was to investigate for a self-administration strategy for testing T and D. Methods Fifty healthy subjects (30 female, 20 male, mean age 27.3 years ± 8.1, range 18-58) were included. T was tested by an examiner (T-as) in a reversed staircase manner and self-tested with randomly presented concentrations (T-rand) and ascending methods of limits (T-aml). D testing was performed with assistance (D-as) and self-administered (D-s). For self-testing, examinees were instructed to perform the Bodor-curves-on-paper^method. Results Mean TDI was 35.9 ± 3.0, range 26.5-42.8. T-as scores were significantly lower than T-aml (p < 0.001) and T-rand (p < 0.05). T-aml was significantly faster than T-rand and T-as modalities (p < 0.001); Paired t test revealed no significant difference of D-as and D-s, in terms of scores and time needed (p > 0.05) and the mean difference was small (0.3). Conclusion The results of this study demonstrate the Bodor-curves-on-paper^method is applicable for D and with restrictions for T testing. Implications Self-administration of olfactory testing using Sniffin' Sticks can, with appropriate instructions, easily be performed and may improve patient care in personnel and (with limitations) time-restricted settings.

“…The test is completed when 7 reversals are reached, and the geometric mean of the last 4 up-down transitions ("reversals") gives the threshold value. 5 A commercial version of this test was later developed. It is called the Smell Threshold Test™ (STT; Sensonics, Inc, Haddon Heights, New Jersey, USA).…”
