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.

- The study aimed to compare two surgical techniques (vertical vs. T-shaped pharyngoplasty) after total laryngectomy and assess factors leading to pharyngocutaneous fistula.
- A total of 57 patients were analyzed, with 14 receiving vertical closures and 43 getting T-shaped closures, revealing that pharyngocutaneous fistula was a common complication in 40.4% of cases.
- Results indicated no significant overall difference in complications between the two techniques, but the T-shaped closure showed a significantly lower rate of tracheal dehiscence, and diabetes was linked to a higher occurrence of fistulas.

Introduction And Importance: Granulomatous chronic invasive fungal rhinosinusitis (GCIFR) is a rare entity with scarce cases reported mainly in subtropical areas. Its prevalence among individuals with clinical suspicion of fungal rhinosinusitis has been reported in approximately 20% in subtropical populations, unlike North America with a prevalence of 0.5%.
