AbstractIn neonates, acquired subglottic stenosis (SGS) is the most serious long term complication of endotracheal intubation. In this case report, we describe the pathological changes in the larynx of a child who died two years after successful treatment, involving corrective surgery, for neonatally acquired SGS. Stenosis, due to dense fibrous connective tissue, was still present at death. However, there was evidence that there had been growth of the laryngeal cartilages. Disruption of the laryngeal cartilages was present anteriorly due to the antecedent surgery but major cricoid cartilage injury secondary to intubation was not seen. The crico-arytenoid joints demonstrated ankylosis and to this was attributed the abnormal quality of voice noted in the child at follow-up. The pathological changes are considered in relation to the pathology of endotracheal intubation and pathogenesis of acquired subglottic stenosis.

AbstractBackground:The diagnosis and treatment of unilateral vocal fold palsy is a common part of otolaryngology practice. In those patients in whom resolution of symptoms is slow, the resulting dysphonia can have a dramatic effect on the patient's quality of voice and life. We have previously described the procedure of direct phonoplasty under local anaesthesia using the transnasal laryngoesophagoscope.Objective:To examine the subjective and objective data for the first five patients to undergo this procedure, in the form of laryngographic speech analysis, perceptual assessment and therapy outcome measures.Results:Analysis showed a statistically significant improvement in voice quality, in all the above assessment categories, following local anaesthetic direct phonoplasty using the transnasal laryngoesophagoscope.Conclusion:Collagen injection via transnasal flexible laryngoesophagoscopy is a particularly useful technique for treating vocal fold medialisation, especially in palliative care patients and those with shortened life expectancy.

Voice And Speech

Introduction. Bilateral recurrent laryngeal nerve paralysis usually occurs after thyroid surgery. In bilateral vocal cord paralysis, the voice is clear or slightly hoarse. The aim of this study was to determine whether the quality of voice and speech significantly deteriorates after the surgical treatment of bilateral recurrent laryngeal nerve paralysis. Material and Methods. The study included 16 patients with bilateral vocal cord paralysis and 16 age- and sex-matched healthy controls. The patients underwent partial arytenoidectomy with posterior cordectomy at the Clinical Center of Vojvodina in the period from January to April 2014. The quality of voice and speech was determined before and after surgical treatment by subjective, objective, aerodynamic voice analysis, and analysis of spontaneous speech, and then compared to the control group. Results. The results of this study showed that in patients with bilateral vocal cord paralysis the voice and speech quality was significantly worse compared to the healthy subjects. The results of subjective and aerodynamic analysis showed that there was a statistically significant deterioration in voice quality after the surgical treatment (p<0.05; p=0.001). The values of objective analysis and analysis of spontaneous speech parameters did not significantly change after the surgery (p>0.05; p=0.401). Conclusion. The patients with bilateral vocal cord paralysis have a poorer voice and speech quality compared to the healthy subjects. After the surgical treatment, patients presented with a lower voice quality, but there were no significant changes regarding the ability of spontaneous speech.

In the last years, the transmission of voice services in converged networks has experienced a huge growth. However, there are still some questions considering the ability of these networks to deliver voice services with acceptable quality. In this paper, we applied analytical modeling and simulation to analyze the quality of voice services using a new index, called MOS a , which considers jointly the MOS index and the availability of the subjacent infrastructure. We consider the influence of different CODECs (G.711 and G.729), queuing policies (Priority Queuing and Custom Queuing), and the warm standby redundancy mechanism. Our goal is to analyze the quality of these services by taking into account overloading conditions in different  architectures/scenarios. These scenarios were constructed using the modeling mechanisms Reliability Block Diagram and Stochastic Petri Nets in addition to a discrete event simulator. Experimental results indicate that the G.711 CODEC has a higher sensitivity both in terms of data traffic volume and allocated network resources in relation to the G.729 CODEC.

<p>Rheumatic mitral stenosis is prevalent in the developing world and presents with a wide array of manifestations. Aphonia and hoarseness of voice secondary to recurrent laryngeal nerve paralysis (Ortner’s syndrome) is an uncommon manifestation of mitral stenosis. We present a case severe mitral stenosis with moderate to severe tricuspid valve regurgitation and severe pulmonary artery hypertension that was masquerading as aphonia and hoarseness of voice for eight months. Mitral valve replacement and tricuspid annuloplasty was done and the quality of voice improved post-surgery. </p>

The Voice

The voice of patients indicated for surgical procedures in treating of dysphonia is already damaged before the operation. The problem, which exists at the level of glottis patients usually try to solve by compensative mechanisms. The quality of voice after the interventions in larynx depends on the type and width of resection, disturbance of physiological phonation mechanisms, and ability to establish optimal phonation automatism. The damage of laryngeal structure, especially its glottic part and vocal cords as its central part, no matter if they are just fibrous or they are partially or totally absent, leads into the development of substitutive phonation mechanisms. The most frequent substitutive mechanisms are: vestibular, ventricular, and chordoventricular phonation. There are some variations of these phonation mechanisms, which are conditioned not only by applied surgical technique, but as they are also individual characteristics, they can be the consequence of applied rehabilitation methods. The diagnosis of voice condition before and after the oncosurgical procedure is done by: laryngostroboscopy, subjective acoustic analysis of voice, and objective acoustic analysis of voice (sonography or computer analysis of acoustic signal). The most of laryngeal carcinomas appear in glottic region, so the function of phonation imposes itself as the objective parameter to measure the quality of life after the oncosurgery of larynx. That is the reason why according to the priority, it is just behind the principle of "oncologic radicalism". Phonation as the most complex laryngeal function seems to have secondary importance. All known operative techniques, especially partial resections, have the preservation of phonation as their goal.

Voice Modulation

The human voice construction is a complex biological mechanism capable of Changing pitch and volume. Some Internal or External factors frequently damage the vocal cords and change quality of voice or do some alteration in the voice modulation. The effects are reflected in expression of speech and understanding of information said by the person. So it is important to examine problem at early stages of voice change and overcome from this problem. ML play a major role in identifying whether voice is pathological or normal in nature. Voice features are extracted by Implementing Mel-frequency Cepstral Coefficients (MFCC) method, and examined on the Convolutional Neural Network (CNN) to identify the category of voice.
