The Usefulness of CC-SIT(Cross-Cultural Smell Identification Test) in Korea / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Many clinical and experimental methods have been developed to evaluate human olfactory function, but there is not a standard test which can be used clinically in Korea. CC-SIT (Cross-Cultural Smell Identification Test) is a smell identification test that consists of 12 items well known in most non-English-speaking cultures. So, authors evaluated the usefulness of CC-SIT in assessing olfactory function in Korea. MATERIALS AND METHODS: One hundred ninety patients who visited clinics complaining of smell loss were categorized to 3 groups (mild hyposmia, moderate hyposmia, severe hyposmia) by questionnaire and 41 healthy subjects were chosen for the normal control group. CC-SIT and a smell threshold test was performed to both patients and controls. The statistical analysis was performed using ANOVA and the Pearson correlation method. RESULTS: There were significant differences in the CC-SIT scores among 3 groups and the severity of hyposmia was correlated with the CC-SIT score. Also, the CC-SIT scores were correlated significantly with the smell threshold. In addition, the difference of familiarity among 12 items was observed. CONCLUSION: CC-SIT is a convenient, practical smell function test which can tell olfactory tunction loss and can he used clinically in Korea.

Effects of Endoscopic Sinus Surgery on Nasality / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: When the impairment of nasal airway patency in patients with chronic sinusitis such as mucosal edema or nasal polyps is resolved after functional endoscopic sinus surgery (FESS), it is expected that patients no longer complain of hyponasal voice. However, patients who have undergone FESS sometimes complain of more hyponasal voice, or thick voice. The purpose of this study was to examine the effect of FESS on voice in terms of nasality. MATERIALS AND METHODS: Thirty-three patients who underwent FESS and thirty normal adults who had no sinus or nasal pathology were selected for this study. We performed nasalance test for patients group before and 3 months after the operation and for the control group without any medication. RESULTS: Patients' preoperative mean nasalance were not low compared with that of control group in all sentences. It was different from perceptual hyponasality they had complained. Postoperative mean nasalance in patients showed statistically significant increase. Higher change ratio of nasalance was noted in Mamma passage than the other passages. CONCLUSION: There was significant increase in nasalance scores after FESS. Thus, we must consider the possibility of voice changes postoperatively in professional voice users.
