\toprule
\textbf{Condition} & \textbf{Brief description} \\
\midrule

Vocal fold polyp &
Benign lesion of the vocal fold, often associated with phonotrauma and irregular vocal fold vibration. \\

Chronic laryngitis &
Persistent inflammation of the laryngeal mucosa, commonly associated with hoarseness and altered voice quality. \\

Laryngeal carcinoma &
Malignant disease of the larynx that may impair vocal fold structure and function. \\

Unilateral vocal fold paralysis &
Impaired mobility of one vocal fold, often resulting in incomplete glottal closure and breathy voice quality. \\

Laryngeal papillomatosis &
Benign epithelial lesions caused by human papillomavirus infection, potentially affecting vocal fold vibration. \\

Reinke's oedema &
Fluid accumulation in the superficial lamina propria of the vocal folds, commonly associated with lowered pitch and rough voice quality. \\

Functional dysphonia &
Voice disorder without a primary structural lesion, often related to inefficient or maladaptive voice use. \\

Vocal fold cyst &
Encapsulated lesion within the vocal fold that may disrupt mucosal wave propagation. \\

Sulcus vocalis &
Groove-like structural alteration of the vocal fold, often associated with glottal insufficiency and dysphonia. \\
