RESUMEN
PURPOSE: Palatal flutter snoring is the most common form of snoring. However, other types of snoring do exist. Does identifying palatal snoring beforehand translate into improved subjective treatment success with palatal stiffening procedures? METHODS: Fifty-three patients presenting with snoring were evaluated with a commercially available device. The proportion (%) and magnitude of palatal flutter (dB) were quantified. Patients then underwent a palatal stiffening procedure and subjective success/failure was assessed. RESULTS: Overall subjective treatment success was 85% (45 of 53). The percent palatal flutter was the most predictive of success (area under ROC = 0.8556, 95% CI = .7428-.9683). Patients exceeding 68% palatal flutter had a 95% (39 of 41) success rate (P = 0.001, Fisher's exact) and an adjusted odds ratio of treatment success of 25.2 (95% CI = 3.22-196, P = 0.002). CONCLUSION: Palatal stiffening treatments are successful in the majority of patients. However, identifying patients with predominant palatal flutter snoring significantly increases the probability of subjective treatment success. EBM RATING: B-2b.

La presbiacusia se caracteriza por una hipoacusia neurosensorial, sobre todo de los agudos, simétrica y progresiva, y una mala inteligibilidad. El recruitment, típico de las hipoacusias cocleares estaría presente en los casos de presbiacusia sensorial que cursan primariamente con cocleopatía. Analizamos en 241 pacientes presbiacúsicos varias variables y las posibles interrelaciones con el recruitment
Presbycusis is characterised by a sensori neural hearing loss mainly in high frequencies, symmetrical and progressive and poor understanding. Recuritment, typical in cochlear hearing loss, would be present in cases of sensorial presbycusis which runs mainly in cochlear pathologies. We analyse variables and their possible interrelations with recruitment in 241 presbycusic patients

In adults, spontaneous otoacoustic emissions (SOAE) have shown a considerable frequency stability. In preterm infants, however, the SOAE proved to show an apparent and consistent upward shift of frequency at increasing postconceptional age (PCA). In 25 ears of 14 preterm infants (PCA, 29.1-41.3 wk) a total of 66 SOAE frequencies were monitored, ranging from 1611 to 5774 Hz. All but one of the SOAE frequencies shifted toward higher frequency. The SOAE frequency shift rate in Hertz per week was proportionally constant relative to the SOAE frequency. The mean shift rate was 0.74 +/- 0.39%/wk. At increasing PCA, the SOAE frequency shift rate tended to slow down. A linear fit through the data predicted the SOAE frequency to stop at about 45-50-wk PCA. The frequency dependence and time course of the SOAE frequency shift strongly suggest cochlear maturation during the last period of gestation.
