Background and objective: Functional endoscopic sinus surgery (FESS) increases the nasal volume, and thereby it can alter the nasal resonance. The objectives were to measure the percentage of nasal resonance following FESS and compare it with healthy individuals with normal nasal findings.Methods: The nasometric analysis of voice was done using n/p/m consonant sounds in 72 individuals with healthy post FESS cavities (group 1) and 72 healthy individuals with normal nasal findings without any nasal pathology (group 2). The scores of nasal resonances were expressed in percentages and were compared between the two groups. Both in group 1 and group 2, 32 (44.4%) were females, and 40(55.6%) were males. In group 1, 51 participants had bilateral FESS cavities, and 21 had unilateral FESS cavities. Kannada was the mother tongue in 30 (41.7%) participants in group 1 and 36 (50.0%) in group 2. Malayalam was the mother tongue in 42(58.3%) participants in group 1 and 36 (50.0%) in group 2.Results: In both cases and control groups, more than 80% of the participants were showing less than 20% of nasal resonance. In group 1, the mean values of/n/p/m sounds were 11.23%, 10.23% and 11.42% respectively, and in group 2 the mean values were 8.27%, 8.58% and 8.58% respectively. But theP value was not statistically significant. Individuals with unilateral FESS cavities had more nasal resonance values compared to bilateral FESS cavities. Similarly, Kannada speaking people had more values compared to Malayam speaking individua.Conclusion: Changes in nasal resonance after FESS is minimal, and it is unnoticed. But it may affect the speech quality in professional voice users, depending on their language. Though the nasometer is considered as the most validated instrument to record nasal resonance, we feel that further standardization is needed to evaluate the nasalance. 展开更多

Vocal individuality is widespread in social animals. Individual variation in vocalizations is a prereq- uisite for discriminating among conspecifics and may have facilitated the evolution of large complex societies. Ring-tailed lemurs Lemur catta live in relatively large social groups, have con- spicuous vocal repertoires, and their species-specific utterances can be interpreted in light of source-filter theory of vocal production. Indeed, their utterances allow individual discrimination and even recognition thanks to the resonance frequencies of the vocal tract. The purpose of this study is to determine which distinctive vocal features can be derived from the morphology of the upper vocal tract. To accomplish this, we built computational models derived from anatomical measurements collected on lemur cadavers and compared the results with the spectrographic out- put of vocalizations recorded from ex situ live individuals. Our results demonstrate that the mor- phological variation of the ring-tailed lemur vocal tract explains individual distinctiveness of their species-specific utterances. We also provide further evidence that vocal tract modeling is a power- ful tool for studying the vocal output of non-human primates. 展开更多
