Cervical Chondrocutaneous Branchial Remnants

Abstract

Cervical chondrocutaneous branchial remnants are rare congenital choristomas. These lesions contain a cartilage core surrounded by skin with adnexal structures and subcutaneous fat. Correspondingly, on ultrasound there is a tubular hypoechoic core surrounded by hyperechoic, while on CT there is central intermediate attenuation surrounded by fat attenuation tissues. These features are exemplified in this sine qua non radiology-pathology correlation article. Management includes complete surgical resection and evaluating for potential associated anomalies, such as other branchial apparatus anomalies, as well as cardiac anomalies.

IntroductionVoice disorders alter the sound signal in several ways, combining several types of vocal emission disturbances and noise. The Phonatory Deviation Diagram (PDD) is a two-dimensional chart that allows the evaluation of the vocal signal based on the combination of periodicity (jitter, shimmer, and correlation coefficient) and noise (Glottal to Noise Excitation – GNE) measurements. The use of synthesized signals, where one has a greater control and knowledge of the production conditions, may allow a better understanding of the physiological and acoustic mechanisms underlying the vocal emission and its main perceptual-auditory correlates regarding the intensity of the deviation and types of vocal quality.ObjectiveTo analyze the performance of the PDD in the discrimination of the presence and degree of roughness and breathiness in synthesized voices.Methods871 synthesized vocal signals were used corresponding to the vowel /ɛ/. The perceptual-auditory analysis of the degree of roughness and breathiness of the synthesized signals was performed using Visual Analogue Scale (VAS). Subsequently, the signals were categorized regarding the presence/absence of these parameters based on the VAS cutoff values. Acoustic analysis was performed by assessing the distribution of vocal signals according to the PDD area, quadrant, shape, and density. The equality of proportions and the chi-square tests were performed to compare the variables.ResultsRough and breathy vocal signals were located predominantly outside the normal range and in the lower right quadrant of the PDD. Voices with higher degrees of roughness and breathiness were located outside the area of normality in the lower right quadrant and had concentrated density.ConclusionThe normality area and the PDD quadrant can discriminate healthy voices from rough and breathy ones. Voices with higher degrees of roughness and breathiness are proportionally located outside the area of normality, in the lower right quadrant and with concentrated density.

IntroductionConsidering the variability of results found in the clinical population using a cochlear implant, researchers in the area have been interested in the inclusion of quality of life measures to subjectively assess the benefits of the implantation.ObjectiveTo assess the quality of life of adult users of CI.MethodsA cross-sectional and clinical study in a group of 26 adults of both genders, with mean duration of CI use of 6.6 years. The Nijmegen Cochlear Implantation Questionnaire and the generic World Health Organization Quality of Life questionnaire were sent electronically.ResultsThe best assessed domain in the quality of life assessment for the cochlear implantation questionnaire was the social domain, whereas for the quality of life questionnaire it was the psychological domain. The variables, gender, time of cochlear implant use and auditory modality did not influence the results of both questionnaires. Only the variable level of education was correlated with the environment domain of the quality of life questionnaire. The variable telephone speech comprehension was associated with a better perception of quality of life for all the domains of the specific questionnaire and for the self-assessment of quality of life in general.ConclusionFrom the users' perspective, both questionnaires showed that the cochlear implant use brought benefits to different aspects related to quality of life.
