Abstract
The present study is a prospective cohort study evaluating the role of ultrasound in diagnosis of laryngeal lesions. The study included 80 patients having different laryngeal lesions. The mean age of our participants was 46.63±6.65 years ranged from 30 up to 60 years. Out of 80 studied participants, 59 (73.8%) were males and 21 (26.3%) were females. With special habit (smoking) was present in 45 patients . The most common clinical presentations was hoarseness which was found in 78 patients (97.5%), followed by cough in 13 patients (16.3%), choking in 3 pateints (3.8%), dysphonia in 3 patients (3.8%), and dysphagia in only 2 cases (2.5%). The primary aim of our work was to assess the efficiency and limitations of ultrasound in detecting and characterizing laryngeal anatomy and study of some laryngeal disorders and their ultrasonographic appearance. All results of ultrasound examination will be compared with laryngoscopic findings to show accuracy of ultrasound in detecting lesions . All studied participants underwent laryngoscopic examination in the outpatient clinic, laryngoscopic findings were variable, 22 patients (27.5%) were having mobility disorders which was the most common finding, followed by chronic laryngitis which was detected in 18 patients (22.5%) ,then Reinke‟s edema detected in 12 patients (15.0%), vocal cord nodules in 10 patients (12.5%), vocal cord polyps in 7 patients (8.8%), laryngeal mass detected in 4 patients (5.0%), leukoplakia in also 4 patients (5.0%), and vocal cord cyst was the least common finding only in 3 patients (3.8%).All the studied patient were examined by ultrasound device after being examined and diagnosed by laryngoscopy, mobility disorders were detected in 26 patients (32.5%), Reinke’s edema was detected in 8 patients (10.0%), nodules was detected in 3 patients (3.8%), polyps were detected in 6 patients (7.5%), cysts were detected in 3 patients (3.8%), laryngeal mass detected in 2 patients (2.5%), and chronic laryngitis and leukoplakia were not detected in any of the examined patients . Considering comparing between laryngoscopic and ultrasonographic findings of the larynx, we found that 22 patients were found to have mobility disorders by laryngoscopic examination and 26 patients found to have mobility disorders by ultrasonographic examination, which means that ultrasonography detected 4 more patients which were not detected to have mobility disorder by laryngoscope. chronic laryngitis was detected in 18 patients by laryngoscopic examination but none of them were detected by ultrasonography to have chronic laryngitis and all of these 18 patients appeared to have normal vocal cords . Also leukoplakia was not detected by ultrasonography in any of examined patients but it was detected by laryngoscopy in 4 patients, all these patients also found with no significant laryngeal abnormality. Reinke’s edema were detected by laryngoscopy in 12 patients, 8 of them were detected in ultrsonography. Vocal cord nodules were diagnosed by laryngoscopy in 10 patients, but only 3 of them were detected by ultrasonography. Vocal cord polyps were detected in 7 patients by laryngoscopy, and detected in 6 patients by ultrasonography. 4 patients were found to have malignant featuring vocal cord mass by laryngoscopic examination; only 2 of them were detected by ultrasonographic examination Vocal cord cyst were detected in 3 patients by laryngoscopy, ultrasonographic examination detected all of them (3 patients). Ultrasonography diagnostic role was not only confined to laryngeal involvement but also able to detect the presence of extra-laryngeal findings,some patients were found to have other findings outside the larynx, upper deep cervical LNs was found in 13 patients (16.2%), malignant featuring LNs was detected in 4 patients (5.0%), residual/recurrent thyroid tissue was detected in one patient (1.3%), the rest of the patients 62 (77.5%) were not having any significant US neck abnormality outside larynx. On summation, ultrasonography doesn’t require extensive settings and can be performed easily and can be an alternative technique to laryngoscopy in patients with sensitive gag reflex, or patients with neck or jaw diseases. Ultrasonography is a non-invasive modality, available at almost all institutions , inexpensive, and need no anesthesia , easily used in examination in children and also safe during pregnancy.
