    Does cooling the tonsillar fossae during thermal welding tonsillectomy have an effect on postoperative pain and healing?
    (SPRINGER, 2013) Karaca, Cigdem Tepe; Celebi, Saban; Oysu, Cagatay; Celik, Oner
    The objective of this study was to evaluate the effect of cooling the tonsillar fossa during thermal welding tonsillectomy on pain and wound healing. Prospective, blinded, clinical study was conducted. 30 patients who underwent tonsillectomy by thermal welding were evaluated. When one of the tonsillar fossa was cooled by isotonic fluid, the other has left untreated. Postoperative pain and mucosal healing pattern were assessed. Data were recorded and statistically analyzed. Healing process of the cooled down tonsillar fossae were significantly better on the 7th and 14th postoperative day (p < 0.01). Control tonsillar fossae had significantly higher pain scores on the 3rd, 7th and 14th postoperative day (p < 0.05). Administration of isotonic fluid, during thermal welding tonsillectomy for cooling tonsillar fossae, accelerates wound-healing process significantly and decreases tonsillectomy related pain complaints post-operatively.

    Efficacy of Dexpanthenol for Pediatric Post-tonsillectomy Pain and Wound Healing
    (ANNALS PUBL CO, 2013) Celebi, Saban; Tepe, Cigdem; Yelken, Kursat; Celik, Oner
    Objectives: 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.

    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, Oncel
    Objective. 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.

    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, Murat
    Objective: 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.

    Voice and Speech Changes in Various Phases of Menstrual Cycle
    (MOSBY-ELSEVIER, 2013) Celik, Oner; Celik, Aygen; Atespare, Altay; Boyaci, Zerrin; Celebi, Saban; Gunduz, Tonguc; Aksungar, Fehime Benli; Yelken, KursAt
    Background. The reproductive system in females undergoes a regular cyclic change known as the menstrual cycle. Laryngeal changes are evident and fluctuate systematically during the reproductive years with the menstrual cycle. The impact of estrogens in concert with progesterone produces the characteristics of the female voice, with a fundamental frequency (F-0) higher than that of male. Objective. To characterize changes in voice and speech in adolescent females in different phases of the menstrual cycle-during menstruation, after menstruation, mid-menstrual cycle, and premenstruation. Materials and Methods. Sixteen adult females who were nonusers of oral contraceptives participated in a cross-sectional study of menstrual cycle influences on voicing and speaking tasks. Acoustic analysis (F-0, intensity, perturbation measurements [jitter and shimmer], and harmonic-to-noise ratio), maximum phonation time (MPT), s/z ratio, and perceptual assessments (grade [G], roughness [R], breathiness [B], asthenia [A], and strain [S] [GRBAS] and Voice Handicap Index-10 [VHI-10]) scales were performed during all phases. Results. None of the acoustic analysis parameters and MPT and s/z ratio measurements revealed statistically significant difference (P > 0.05). Perceptual voice assessment scales either clinician based or patients self-evaluated showed significant differences among phases (P < 0.05). Conclusions. The objective voice analysis methods, such as acoustic analysis, MPT, and s/z ratio, determined no difference; however, the subjective voice analysis methods, such as clinician-based perceptual assessment (GRBAS) and patients self-evaluation (VHI-10) scales, demonstrated significant changes during different phases of menstrual cycle.
