Yayın Clinical Considerations in Speech and Language Therapy in Turkish Transgender Population(Mosby-Elsevier, 2021) Oğuz, Özlem; Ayran, Beril; Yelken, KursatObjective. Transgender people aim to increase and improve their quality of life by demanding voice and communication intervention services, however clinical recommendations regarding assessment and intervention in the transgender population are based on others' practice, experiences, assumptions. The present study aims to give clinical considerations in speech and language therapy for transgender populations. Method. Thirty-one transgender subjects were taken in to the present study after applying exclusion criteria. Participants were excluded: If they do not define themselves as transgendered and have not taken part in any reassignment of gender procedure and also they do not want to take part in any gender procedures. The participants were given a survey, which included questions related to demographic information, procedures during transition process, priorities regarding to voice and nonverbal communication and as a final part awareness and knowledge in speech and language therapy. Results. Transgender people had benefited from many procedures and/or approaches during their transition process from hormone therapy to voice surgery. Participants stated that pitch was the most important vocal quality among others (41.9%) while facial expression (38.7%) was the most important one among other nonverbal communication skills. None of the participants had speech and language therapy sessions during their transition process. With regards to awareness of speech and language therapy services, 17 of the participants (54.8%) said they did not know that they could apply for the services. Twelve participants (38.7%) reported that they were aware of the services and they could apply in order to change their voice characteristics, nine participants (29%) informed that they could see a speech and language therapist for nonverbal communication skills while seven participants (22.6%) said it was for social language use. The participants who knew about speech and language therapy had knowledge about the therapy services via online resources. Conclusion. Transgender participants are not aware of speech and language therapy services in Turkey.Yayın Efficacy of Dexpanthenol for Pediatric Post-tonsillectomy Pain and Wound Healing(ANNALS PUBL CO, 2013) Celebi, Saban; Tepe, Cigdem; Yelken, Kursat; Celik, OnerObjectives: We evaluated the efficacy of dexpanthenol in managing pediatric post-tonsillectomy pain and wound healing and sought to discover which of two surgical tonsillectomy techniques provides better healing and less postoperative pain. Methods: One hundred twenty patients who underwent tonsillectomy were equally randomized to thermal welding and cold dissection groups. Dexpanthenol pastilles were given to half of each group. Postoperative throat pain was determined with a visual analog scale on the 1st, 3th, 7th, and 14th days, and mucosal healing patterns were assessed on the 7th and 14th days. Results: Regardless of surgical technique, post-tonsillectomy throat pain was significantly less in the dexpanthenol groups than in the placebo groups (p < 0.05), and tonsillar wound healing was significantly better in the dexpanthenol groups than in the placebo groups (p < 0.05). When a comparison was made with regard to surgical technique, wound healing was significantly better in the cold dissection group (p < 0.05), whereas postoperative throat pain was less in the thermal welding group (p < 0.05). Conclusions: Postoperative administration of dexpanthenol significantly accelerates the wound healing process and decreases tonsillectomy-related pain complaints.Yayın Receiver operating characteristic analysis of acoustic and electroglottographic parameters with different sustained vowels(Taylor & Francis Ltd, 2022) Yılmaz, Göksu; Cangi, M. Emrah; Yelken, KursatObjective To examine the power of the parameters obtained from different sustained vowels used in acoustic and electroglottographic (EGG) voice evaluation protocols to discriminate between dysphonic and non-dysphonic voice quality. Methods Sixty non-dysphonic participants and 30 dysphonic participants were included in the study. In addition to the time domain amplitude and frequency perturbation parameters obtained from the sustained phonation of /lambda/-/e/-/i/-/u/ vowels, several frequency-domain spectral/cepstral parameters and EGG parameters were evaluated. The classification performance of the acoustic and electroglottographic measures was quantified using analysis and receiver operating characteristic (ROC) curve analysis. Results As a result of ROC analysis, the discriminative diagnostic performance (area under the curve, AUC) of the test for low-vowel (/lambda/-/e/) phonation was higher than values obtained from high-vowel (/i/-/u/) phonation. For /lambda/ and /e/ sustained vowels, the parameters exhibiting the highest discrimination were fundamental frequency standard deviation (f(o)/STD), cepstral peak prominence (CPP), relative average perturbation (RAP), pitch perturbation quotient (PPQ), and jitter percent (JITT). In the EGG parameters, on the other hand, average jitter and periodicity parameters obtained from front vowels (/e/-/i/) were found to have higher AUC values compared to back vowels (/lambda/-/u/). Conclusions In acoustic analyses, /lambda/ and /e/ sustained vowels give the highest diagnostic performance. In the electroglottographic evaluation, on the other hand, /e/ and /i/ vowels, when the position of the tongue is forward, have better classification performance compared to /lambda/ and /u/ vowels, when the position of the tongue is back.Yayın Septorhinoplasty With Spreader Grafts Enhances Perceived Voice Quality Without Affecting Acoustic Characteristics(MOSBY-ELSEVIER, 2012) Celik, Oner; Boyaci, Zerrin; Yelken, Kursat; Atespare, Altay; Celebi, Saban; Koca, OncelObjective. To identify the effect of septorhinoplasty with spreader grafts on patients' perception of voice and to measure formant frequencies that may be responsible for perceived changes in voice quality. Methods. A total of 20 patients who underwent septorhinoplasty and had spreader grafts placed during the operations were included. All subjects were tested within the week before surgery and 1-3 months postoperatively by means of perceptual assessment (Voice Handicap Index-10 [VHI-10] and self-assessment of hypo/hypernasality), acoustic analysis, and formant frequency analysis. Results. The mean of VHI-10 score was decreased from 9.44 +/- 6.1 to 5.1 +/- 3.94 postoperatively (P = 0.03). Fifteen patients (75%) perceived their voices to be hyponasal before surgery, but only three perceived the hyponasality to persist after surgery (P < 0.001). No patient perceived the voice to be hypernasal either before or after surgery. Fifteen patients (75%) perceived their overall voice quality to be improved, whereas five patients perceived no change. None of the patients perceived their voice to be worse after surgery. There were no significant differences between pre- and post-operative acoustic analysis and formant frequency analysis (P > 0.05). Conclusion. Septorhinoplasty with spreader grafts significantly improved patients' perception of voice; however, acoustic analysis and formant frequency analysis of nasalized vowels did not reveal any significant differences after the operation.Yayın Thermal welding vs. cold knife tonsillectomy: A comparison of voice and speech(ELSEVIER IRELAND LTD, 2011) Celebi, Saban; Yelken, Kursat; Celik, Oner; Taskin, Umit; Topak, MuratObjective: To compare acoustic, aerodynamic and perceptual voice and speech parameters in thermal welding system tonsillectomy and cold knife tonsillectomy patients in order to determine the impact of operation technique on voice and speech. Methods: Thirty tonsillectomy patients (22 children, 8 adults) participated in this study. The preferred technique was cold knife tonsillectomy in 15 patients and thermal welding system tonsillectomy in the remaining 15 patients. One week before and 1 month after surgery the following parameters were estimated: average of fundamental frequency, Jitter, Shimmer, harmonic to noise ratio. formant frequency analyses of sustained vowels. Perceptual speech analysis and aerodynamic measurements (maximum phonation time and s/z ratio) were also conducted. Results: There was no significant difference in any of the parameters between cold knife tonsillectomy and thermal welding system tonsillectomy groups (p > 0.05). When the groups were contrasted among themselves with regards to preoperative and postoperative rates, fundamental frequency was found to be significantly decreased after tonsillectomy in both of the groups (p < 0.001). First formant for the vowel /a/ in the cold knife tonsillectomy group and for the vowel /i/ in the thermal welding system tonsillectomy group, second formant for the vowel /u/ in the thermal welding system tonsillectomy group and third formant for the vowel /u/ in the cold knife tonsillectomy group were found to be significantly decreased (p < 0.05). Conclusions: The surgical technique, whether it is cold knife or thermal welding system, does not appear to affect voice and speech in tonsillectomy patients. (C) 2010 Elsevier Ireland Ltd.
