Abstract
CTDs are common and can lead to significant voice impairment. The aim of this study was to evaluate the correlation between the type of CTD and the presence of various vocal fold lesions observed during laryngoscopic examination.
The study included 60 patients diagnosed with a CTD who underwent laryngoscopic examination. Patients were divided into three groups: 36 with rheumatoid arthritis (RA), 10 with systemic lupus erythematosus (SLE), and 14 with other CTDs. They were recruited from the outpatient clinic of Phoniatric Unit and rheumatology unit, Assiut University Hospital during the period from may 2021 to may 2022. The presence of various vocal fold lesions was recorded during laryngoscopic examination, and the dysphonia severity grade and strained character of dysphonia were evaluated.
The data suggests that patients with RA had a higher incidence of VF redness (63.9%) and both arytenoid congestion (75%) compared to patients with SLE and other CTDs. On the other hand, patients with SLE had a higher incidence of VF oedema (80%) and phonatory gap (60%) compared to patients with RA and other CTDs. The incidence of abnormal mobility, VF nodule, bamboo nodule, cricoarytenoid joint displacement, and cricoarytenoid joint arthritis was low and not significantly different between the different CTD groups.
This study demonstrates a correlation between the type of CTD and the presence of various vocal fold lesions. Patients with RA were found to have a higher incidence of VF redness and both arytenoid congestion, while patients with SLE had a higher incidence of VF oedema and phonatory gap. Further studies with larger sample sizes are needed to validate these findings and to gain a better understanding of the relationship between CTDs and laryngeal manifestations.
