Laryngeal Fibrolipoma: A Case Report.

Fibrolipoma is a benign mesenchymal tumor with a rare presentation in the aerodigestive tract. This lesion is characterized by a slow growth rate and symptoms such as dysphagia, dysphonia, and dyspnea due to the mass effect on neighboring structures. Achieving optimal surgical outcomes requires indirect laryngoscopy and imaging techniques such as computed tomography (CT) or magnetic resonance imaging (MRI), which provide useful information for a better understanding of the underlying pathology.

Smoothed Cepstral Peak Prominence: A Comparison Between Dysphonic and Non-dysphonic Mexican Adults Employing the Praat Software.

Background Acoustic vocal analysis provides objective and measurable values for various voice parameters, such as fundamental frequency (F0), shimmer, jitter, and the noise-to-harmony ratio (NHR). In severely dysphonic patients, who present increased variability in glottic cycles and abnormalities in vocal intensity, conventional acoustic analysis is an unreliable predictor of dysphonia. The logarithmic transformation of the vocal spectrum (cepstrum) allows capturing the signal without relying on recording technique, frequency, or vocal intensity.
