“…The present analysis did not find significant associations between measured olfactory dysfunction and some previously identified risk factors including head trauma [91] and sinonasal problems [92]. These risk factors did associate with the risk of self-reported smell alterations in our previous analysis of over 3600 participants of NHANES 2011–2012 [9].…”

“…The question asked in order to identify head trauma specified loss of consciousness but did not inquire about how recently the event had occurred or the frequency of occurrence (repeated events). The type of head trauma associated with olfactory dysfunction [91] may involve an interaction between physical activity, head trauma, and olfactory dysfunction. In addition, sinonasal problems can cause fluctuations in olfactory function that may not have been detected in the single NHANES olfactory test but may still have been recalled and mentioned in self-reports.…”

The U.S. NHANES included chemosensory assessments in the 2011–2014 protocol. We provide an overview of this protocol and 2012 olfactory exam findings. Of the 1818 NHANES participants aged ≥40 years, 1281 (70.5 %) completed the exam; non-participation mostly was due to time constraints. Health technicians administered an 8-item, forced-choice, odor identification task scored as normosmic (6–8 odors identified correctly) versus olfactory dysfunction, including hyposmic (4–5 correct) and anosmic/severe hyposmic (0–3 correct). Interviewers recorded self-reported smell alterations (during past year, since age 25, phantosmia), histories of sinonasal problems, xerostomia, dental extractions, head or facial trauma, and chemosensory-related treatment and changes in quality of life. Olfactory dysfunction was found in 12.4 % (13.3 million adults; 55 % males/45 % females) including 3.2 % anosmic/severe hyposmic (3.4 million; 74 % males/26 % females). Selected age-specific prevalences were 4.2 % (40–49 years), 12.7 % (60–69 years), and 39.4 % (80+ years). Among adults ≥70 years, misidentification rates for warning odors were 20.3 % for smoke and 31.3 % for natural gas. The highest sensitivity (correctly identifying dysfunction) and specificity (correctly identifying normosmia) of self-reported olfactory alteration was among anosmics/severe hyposmics (54.4 % and 78.1 %, respectively). In age- and sex-adjusted logistic regression analysis, risk factors of olfactory dysfunction were racial/ethnic minority, income-to-poverty ratio ≤ 1.1, education

“…However, the vast majority of nasal bone fractures are treated by closed reduction with rates of successful reduction ranging between 70% and 95% [ 1 5 7 8 9 10 ]. Posttraumatic olfactory dysfunction is a recognizable concern in these patients [ 11 12 13 14 15 16 17 18 19 ]. The decline in olfactory function can be caused by disruption of sinus tract, olfactory nerve injury, injury to the connections between central olfactory structures as well as indirect airflow disturbance by factors associated with operation such as packing material [ 16 ].…”

BackgroundAll nasal bone fractures have the potential for worsening of olfactory function. However, few studies have studied the olfactory outcomes following reduction of nasal bone fractures. This study evaluates posttraumatic olfactory dysfunction in patients with nasal bone fracture before and after closed reduction.MethodsA prospective study was conducted for all patients presenting with nasal bone fracture (n=97). Each patient consenting to the study underwent the Korean version of Sniffin' Sticks test (KVSS II) before operation and at 6 month after closed reduction. The nasal fractures were divided according to the nasal bone fracture classification by Haug and Prather (Types I–IV). The olfactory scores were compared across fracture types and between preoperative and postoperative settings.ResultsOlfactory dysfunction was frequent after nasal fracture (45/97, 46.4%). Our olfactory assessment using the KVSS II test revealed that fracture reduction was not associated with improvements in the mean test score in Type I or Type II fractures. More specifically, the mean posttraumatic Threshold, discrimination and identification score decreased from 28.8 points prior to operation to 23.1 point at 6 months for Type II fracture with septal fracture.ConclusionOur study has revealed two alarming trends regarding post-nasal fracture olfactory dysfunction. First, our study demonstrated that almost half (46.4%) of nasal fracture patients experience posttraumatic olfactory dysfunction. Second, closed reduction of these fractures does not lead to improvements olfaction at 6 months, which suggest that olfactory dysfunction is probably due to factors other than the fracture itself. The association should be further explored between injuries that lead to nasal fracture and the mechanism behind posttraumatic olfactory dysfunction.
