Article Title | Assessing parosmia patients: a study on the evaluation method using a self-administered odor questionnaire for parosmia |
Abstract | Background: Parosmia symptoms are difficult to quantify due to their heterogeneity among patients, and thus a clinical challenge. This study aimed to assess parosmia with Self-Administered Odor Questionnaire for Parosmia (SAOQ-P), a modification of the widely used SAOQ in Japan. The primary objective was to assess the effectiveness of SAOQ-P in identifying parosmia symptoms and its potential integration into the clinical assessment process. The study also explored traditional olfactory test differences between patients with and without parosmia. Methods: Patients at Jikei Smell Clinic that presented between May 2022 and November 2022 were recruited and administered the SAOQ-P, which had an added question about changes in the perception of 20 daily odors compared to the original SAOQ. Traditional olfactory tests utilized T&T olfactometry and Open Essence. Results: Of 279 patients, 81 had parosmia, while 198 did not exhibit parosmic symptoms. Parosmia prevalence was influenced by the cause of olfactory dysfunction, with post-infectious and post-COVID-19 patients showing higher parosmia rates. Among parosmia patients, 87% reported changes in their perception of at least one odor assessed by SAOQ-P, with coffee, stool, and perfume most commonly affected. Traditional olfactory tests showed no significant differences between parosmia and non-parosmia groups. The number of odors causing parosmia was negatively correlated with age. Conclusion: SAOQ-P offers a promising approach to assess and quantify parosmia symptoms, seamlessly integrating into clinical assessments. SAOQ-P identified parosmia in 87% of patients and revealed insights into triggering factors. Traditional olfactory tests' limitations underscore the need for more accurate, patient-centric diagnostic approaches for parosmia. |
