“…STATA® 16.0 (StataCorp., College Station, TX, USA) software was used for the meta-analysis. The difference in means in olfactory function was calculated for 2 studies reporting BSIT scores (12,18) , 4 reporting CCCRC scores (6,13,15,20) , 4 reporting all three subsets of the Sniffin' Sticks test (4,5,14,21) and 2 reporting SST OI scores (10,11) .…”

“…For clearer interpretation, the meta-analysis was conducted on a raw difference in means instead of a standardized one. The studies by Kokubo et al (21) , Miyake et al (16) , and Tutar et al (2) were excluded because no numerical values were reported for the olfactory test results. The study by Randhawa et al (17) was excluded because standard deviations were not reported.…”

“…Seven studies included data on the distribution of patients as normosmic, hyposmic or anosmic. In 4 of those studies the majority of patients were normosmic (2,15,16,21) , whereas in 3 studies the majority of patients had OD before surgery (4,5,19) . The study by Valsamidis et al (5) included healthy subjects and found that patients with septal deviation had worse olfaction than controls.…”

“…Septoplasty is the standard treatment for nasal septum deviation because it generally results in improved nasal airflow and resolution of nasal obstruction symptoms; however, it is not without side effects (9) . To date, there are multiple studies evaluating the effects of septal surgery on olfactory function and nasal symptoms with conflicting results (2,(4)(5)(6)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21) .…”

BACKGROUND: Septoplasty is one of the most frequently performed surgeries. However, there remains a question as to the effect of such intervention on the sense of smell. This study aims to examine the available evidence regarding the effect of septoplasty on the sense of smell. METHODS: A database search was performed using PubMed, ScienceDirect, Google Scholar and The Cochrane Library databases from January 1990 to February 2020. Search terms included smell, olfaction, odor, septum, septoplasty, and septorhinoplasty. A meta-analysis was performed with 12 studies that provided sufficient data on change in olfaction. RESULTS: 14 studies met the inclusion criteria, and 2 additional studies were included manually; comprising a total of 996 patients and 25 controls. Significant improvement in olfactory test scores was observed in all tests. Pre- and postoperative differences in means were 0.63 for BSIT, 0.80 for CCCRC test, 1.16 for odor threshold, 1.43 for odor discrimination, and 1.18 for odor identification. CONCLUSIONS: Septoplasty seems to improve olfactory function. However, the outcome of this intervention is discrete and not equal for all patients, so further randomized trials are needed to confirm current findings.

Background In the 5 years that have passed since the publication of the 2018 International Consensus Statement on Allergy and Rhinology: Allergic Rhinitis (ICAR‐Allergic Rhinitis 2018), the literature has expanded substantially. The ICAR‐Allergic Rhinitis 2023 update presents 144 individual topics on allergic rhinitis (AR), expanded by over 40 topics from the 2018 document. Originally presented topics from 2018 have also been reviewed and updated. The executive summary highlights key evidence‐based findings and recommendation from the full document. Methods ICAR‐Allergic Rhinitis 2023 employed established evidence‐based review with recommendation (EBRR) methodology to individually evaluate each topic. Stepwise iterative peer review and consensus was performed for each topic. The final document was then collated and includes the results of this work. Results ICAR‐Allergic Rhinitis 2023 includes 10 major content areas and 144 individual topics related to AR. For a substantial proportion of topics included, an aggregate grade of evidence is presented, which is determined by collating the levels of evidence for each available study identified in the literature. For topics in which a diagnostic or therapeutic intervention is considered, a recommendation summary is presented, which considers the aggregate grade of evidence, benefit, harm, and cost. Conclusion The ICAR‐Allergic Rhinitis 2023 update provides a comprehensive evaluation of AR and the currently available evidence. It is this evidence that contributes to our current knowledge base and recommendations for patient evaluation and treatment.

ObjectivesFactors affecting persistence of COVID‐19‐related olfactory dysfunction (OD) remain partially unknown. We aim to evaluate the clinical factors which could influence olfactory performance in patients with persistent COVID‐19‐related smell loss.MethodsA retrospective analysis of 100 patients with persistent COVID‐19‐related OD was performed between October 2020 and December 2022 at a single‐center long‐COVID smell clinic. All subjects underwent smell assessment using Sniffin' Sticks (S'S) extended test, nasal endoscopy, nasal airflow evaluation (peak nasal inspiratory flow [PNIF]), allergy test (skin prick test [SPT]) for common aeroallergens, MRI of the head and patient‐reported outcome measures (PROMs—VAS, SF‐36, Short QOD‐NS, SNOT‐22). Based on S'S score, subjects were divided into normosmics (TDI ≥ 30.75) and dysosmics (TDI < 30.75).ResultsThe median age was 42 years and the median length of patient‐reported OD was 1.4 years. 20 patients (20.0%) were normosmic at the time of S'S assessment. Dysosmic patients were found to have significantly lower scores at the SF‐36 health domains for energy/fatigue (p = .0004) and emotional wellbeing (p = .04) when compared to normosmics. A moderate correlation (r = .45–.59) between S'S scores and some PROMs was also demonstrated. At the multivariate analysis higher PNIF scores positively influenced odor threshold (p = .001) while positivity to SPT negatively influenced odor identification (p = .04).ConclusionsImpairment of nasal airflow and sensitivity to aeroallergens can negatively affect olfactory performance in COVID‐19‐related OD. Long‐COVID smell loss deeply affects QoL although recovery of olfaction can bring it back to a normal range.Level of EvidenceIV.
