Unilateral vocal fold paralysis resulting in glottic incompetence can cause impairment of laryngeal functions, including airway protection and phonation. The objective of this study is to present an easy new technique for harvesting and injection of abdominal fat into the vocal fold for patients with unilateral vocal fold paralysis. This is a retrospective study of patients carried out on 16 patients suffering from unilateral vocal fold paralysis resulting from different etiologies. All patients were subjected to the protocol of voice assessment pre- and postoperatively. All patients were subjected to fat injection of the paralyzed vocal fold. There was a statistically significant difference between the pre- and postoperative grade of voice parameters. Vocal fold injection using fat medializes a paralyzed vocal fold by increasing vocal fold volume. Fat injections are safe and easily mastered; and in the absence of the standard settings for fat harvesting and injection, it could be performed with minimal equipment that are readily available in any operating room.
Objective Platelet-rich plasma has gained interest over the two last decades, mainly because of its role in regenerative medicine. This work aimed to assess the role of intra-operative local application of platelet-rich plasma gel in the improvement of quality of voice after microlaryngeal surgery. Method This was a prospective comparative study that included 40 patients undergoing microlaryngeal surgery for benign vocal fold lesions. There were two groups divided equally into study group A and control group B. The assessment of voice was performed by videostroboscopy and acoustic analysis pre-operatively and at two weeks and one and three months post-operatively. Results The data demonstrated that all the stroboscopic and acoustic parameters showed significant improvement in both groups. Group A showed significant improvement regarding acoustic parameters at the third post-operative follow up when compared with group B. Conclusion Platelet-rich plasma has a beneficial effect on voice quality following microlaryngeal surgery based in particular on acoustic parameters.
Background Prosody is an important acoustic and linguistic component of speech that greatly contributes to speech intelligibility. Speech of hearing-impaired children shows various deviations from their normal-hearing counterparts due to complex physiological mechanisms. Methods Acoustic analysis of the prosodic production of hearing-impaired, cochlear-implanted, Egyptian children, and comparing them to a normal group of normal-hearing peers, using objective measures. Cases group included 30 hearing-impaired verbal children from the age of 6 to 10 years using cochlear implant devices. The controls group included 30 normal-hearing children within the same age range. Recording and analysis of both groups’ speech samples were done using real-time pitch software, generic syllabic rate, and intonation stimulability software. Results Significant differences were found between the two studied groups where decreased pitch range, increased loudness variability, increased pause duration, and decreased syllabic rate were found in hearing-impaired children. Conclusion Prosodic differences between hearing-impaired children with cochlear implants and normal-hearing children could be measured objectively giving a numeric profile that could be used as a measure to monitor the progress of their speech with therapy.
Background Dysphonia is a disorder characterized by change in voice quality, pitch, loudness, or vocal effort that impairs communication or reduces voice-related quality of life. Childhood dysphonia has several adverse educational and psychosocial implications. Dysphonic children are not aware or not bothered by their voice disorder. Although dysphonia might, in some cases, improve by itself in adulthood, it can be of important value to treat the dysphonic voice already during childhood. Aim The aim of this study was to adapt and formulate a program of voice intervention for childhood dysphonia and apply it on Egyptian children to explore its effectiveness as a therapeutic tool. Patients and methods This study was conducted on 20 children of both sexes attending the Phoniatrics Unit in Alexandria Main University Hospital complaining of dysphonia. The remediation program aims to improve dysphonia in children using a combination of indirect and direct treatment techniques. It is a modification of The Boone Voice Program for Children combined with new technologies such as the voice games by Kay Elementrics. It is designed to provide the clinician with step-by-step procedures and materials to remediate voice disorders in school-aged children. The program was translated to Arabic and a number of modifications were done in order to adapt it to the Egyptian children. Results The study showed effectiveness of the remediation program for childhood dysphonia regarding some of the auditory perceptual assessment and acoustic analysis values. Some of the laryngeal examination findings also showed improvement post-therapy. The study showed significant relation between the children’s age, sex, diagnosis, and some pretherapy and post-therapy findings. Conclusion Data from the current study suggests that voice therapy may prove to be a valid alternative to just planned follow-up.
Background Although dysphonia is a common symptom in children, there is lack of mass screening studies to cover its prevalence rate in the Egyptian Alexandrian schools. The aim of the work was to screen Alexandrian school-age children for dysphonia in order to determine the prevalence and to detect its possible predisposing factors. The study was carried out on 1913 school children (4th-6th grade), age range of 9-13 years and presenting the seven Alexandrian Educational districts. All patients were screened for the presence of dysphonia. The grade of dysphonia was assessed by a phoniatrician using perceptual auditory evaluation. Determination of possible predisposing factors was done through the application of a questionnaire. Only 317 students responded to the questionnaire. Results There was a significant difference between dysphonic and non-dysphonic as regards gender, and school grade. Having a smoking family member and conducting activities requiring high vocal demands were recorded with the highest percentage among dysphonic children. Conclusion The Study revealed a prevalence rate of childhood Dysphonia of 12.4%. The presence of chest problems, prolonged loud cry, temperament personality and passive smoking predisposed to dysphonia in primary school students.
