声带注射治疗声带麻痹及检测喉发音的研究

对30例不同病因所致单侧声带麻痹患者,采用经环甲间隙穿刺声带注射硅胶的方法进行治疗.治疗前后对患者的最长发音时间(MPT)、喉平均呼气流率(MFR)、基频值(F_0)、声强级(SPL)、频率微扰商(PPQ)、振幅微扰商(APQ)、噪声能量级(NNE),频闪喉镜下声带振动发音过程中的对称性(SYM)、规则性(REG)、振幅(AMP)、闭合状态(GLO)、粘膜波动(MUC)、等质性(NON)和嗓音心理听觉评价参数:音哑总分度(G)、粗糙型(R)、气息型(B)、无力型(A)、紧张型(S)进行检测,并对测试结果进行统计学分析.实验结果表明,上述各项参数值在治疗后较治疗前有明显改善,其中MPT、GLO值的增高,MFR、PPQ、APQ、NNE值下降表现最明显:心理听觉评价参数GRBAS值治疗后较治疗前也有明显好转.对各参数进行统计学分析得出:声带麻痹嗓音中噪音成分主要同声带振动的规则性、振幅和粘膜波呈正相关(P<0.05或 P<0.01).声带麻痹嗓音的主观心理听觉评价是以气息型和无力型为主.它主要与喉平均呼气流率,声带振动的规则性、闭合度、振幅、声带粘膜波及对称性呈正相关.从而证明,经环甲间隙声带注射硅胶治疗单侧声带麻痹是一种简单、实用、安全的治疗方法.若一次不成功还可以重复治疗.

Relationships between the degree of lesion and that of vocal dysfunction in vocal fold polyp

Relationships between the degree of lesion and that of vocal dysfunction were investigated in 122 cases of vocal fold polyp. A normalized size of polyps and glottic gap were correlated to the results of phonatory ability tests, stroboscopic investigations, acoustic analyses, and perceptual evaluations. There was no significant correlation between the size and the gap. The size of polyp was negatively correlated to fundamental frequency, whereas it was positively correlated to roughness of voice, asymmetry of vocal fold vibration, irregularity of vocal fold vibration, pitch perturbation quotient, amplitude perturbation quotient, and normalized noise energy. The glottic gap showed negative correlations to maximum phonation time and sound pressure level, and positive correlations to mean airflow rate and fundamental frequency.     

Long-term outcomes of basic fibroblast growth factor treatments in patients with vocal fold scarring,aged vocal fold,and sulcus vocalis

ObjectiveFibrotic changes in the vocal fold mucosa have been observed in patients with vocal fold scarring, aged vocal fold, and sulcus vocalis, which often lead to severe voice disorders. Previous research suggests that the basic fibroblast growth factor (b FGF) improves variations in vocal fold properties [1,2]. Although clinical studies on b FGF treatments have been conducted [3,4,5], these studies only demonstrated the efficacy of this drug over a short period. The present study is the first to investigate the long-term efficacy of b FGF treatment.Methodsb FGF injections were performed in six patients from January of 2016 to December of 2017 at our institution. Patient follow-up continued for at least two years after the last injection. Three patients had vocal fold scarring, two had aged vocal fold atrophy, and one patient had sulcus vocalis. Each vocal fold was injected with 10 µg of b FGF four times. Voice and stroboscopic examinations were performed after surgery (at one month, three months, six months, one year, two years). Fundamental frequency, maximum phonation time (MPT), mean flow rate (MFR), amplitude perturbation quotient (APQ), pitch perturbation quotient (PPQ), and noise-to-harmonic ratio (NHR), and voice handicap index-10 (VHI-10) were examined and compared statistically between the pretreatment time and at each posttreatment time point.ResultsThe speaking F0 had an obvious decreasing tendency, with significant differences suggesting the increase in volume in the vocal folds. Aerodynamic parameters also showed small improvements. The most remarkable improvement was observed in the acoustic parameters, indicating that the treatment could improve the vocal fold to make vibrations symmetrically and regularly for a long period. Achievement of symmetry and regularity on vocal fold vibrations suggested the property changes had happened in the vocal folds. Consequently, the score of VHI-10 had improved, indicating high patient satisfaction with this treatment.Conclusionb FGF injections could be a reliable treatment option for diseases that deteriorate the property of vocal fold.     

Objective voice analysis after autologous fat injection for unilateral vocal fold paralysis

This study was designed to objectively compare a patient's voice after onset of unilateral vocal fold paralysis (UVFP) to his or her own normal voice, and to compare the results after treatment by intrafold injection of autologous fat. Acoustic recordings were obtained for 2 male patients before thoracic surgery and after the onset of iatrogenic left UVFP. Vocal fold augmentation was performed 10 days after UVFP. The acoustic recordings were repeated within 3 days and at 1 month. The phonation quotient, pitch perturbation quotient, amplitude perturbation quotient, harmonics-to-noise ratio, cepstral peak prominence, and long-term average spectrum were analyzed. All parameters improved after treatment, with a return to preparalytic values for most. During the first month, some deterioration was noted. This is the first study comparing a subject's own normal voice to his or her voice after vocal fold augmentation. We recommend overinjection of fat if vocal fold atrophy is expected.     

声带振动功能的无创检测

Surgical effects of type-I thyroplasty and fat injection laryngoplasty on voice recovery

ObjectiveType-I thryroplasty, also known as medialization thyroplasty (MT) and autologous fat injection laryngoplasty (FIL) are one of the main surgical treatments for unilateral vocal fold paralysis (UVFP). Both procedures have the same concept of completing the glottal closure by medializing the vocal fold, although the surgical approaches are quite different. In order to assess these surgical effects, we examined the treatment outcomes and benefits of the two surgeries.MethodsWe collected data from the 135 phonosurgeries that we performed out of 375 patients with UVFP at Osaka Voice Center, Osaka Kaisei Hospital from January 2009 to February 2013. After excluding cases with glottal level differences on phonation, either MT or FIL were performed on 80 cases. The inclusion criteria for the present study were: (1) patients had no history of previous phonosurgery, and (2) functional evaluations were available before/after surgery. Consequently, 43 participants (12 for MT and 31 for FIL) were enrolled in this study. Surgical effects were evaluated by means of the maximum phonation time (MPT), pitch period perturbation quotient (PPQ), amplitude perturbation quotient (APQ), and harmonic to noise ratio (HNR) just before, one month, and 6 months after surgery.ResultsBoth MT and FIL showed significant improvement in MPT (MT, p = 0.005; FIL, p < 0.001) and PPQ (MT, p = 0.047; FIL, p = 0.041) at 1 month postoperation. We also compared the variation of each variable between the two procedures, but there were no significant differences in these parameters. However, MPT, APQ, and HNR at the post-MT after 6 months worsened compared to those at 1 month posttreatment, whereas MPT showed only a slight decrease from the 1st month to the 6th month in those with FIL.ConclusionBoth MT and FIL were effective for the voice recovery in patients with UVFP. Our findings suggest that surgical results in FIL might be better than those in MT 6 months after surgery, although there were no significant differences between these two procedures 1 month postoperation.     

A retrospective analysis of revision framework surgeries for unilateral vocal fold paralysis

IntroductionRevision framework surgeries might be required for unilateral vocal fold paralyses. However, outcomes and indications of revision surgeries have not been adequately documented. For a better understanding of indications for the procedure and to help in achieving better vocal outcomes, we performed a retrospective chart review of patients who underwent revision framework surgeries for unilateral vocal fold paralysis.ObjectivesThis study aimed to present clinical features of patients who underwent revision framework surgeries for the treatment of unilateral vocal fold paralysis.MethodsOf the 149 framework surgeries performed between October 2004 and October 2019, 21 revision framework surgeries were performed in 19 patients. Self-assessments by patients using the voice handicap index-10 questionnaire, and objective aerodynamic and acoustic assessments performed pre- and post-operatively were analyzed using the Wilcoxon’s signed-rank test for paired comparisons.ResultsUndercorrection was indicated as reasons for revision surgeries in all cases. The revision techniques included type I thyroplasty, type IV thyroplasty, and arytenoid adduction, and revision surgeries were completed without any severe complication in all cases. Pre- and post-operative voice handicap index-10 scores were obtained in 12 cases, and other parameters were evaluated in 18 cases. Significant improvements were observed in voice handicap index-10 scores, maximum phonation time, mean flow rate, Current/Direct Current ratio, and pitch perturbation quotient.ConclusionUndercorrection was observed in all patients who underwent revision framework surgeries for unilateral vocal fold paralysis, and the initial assessment and planning are thought to be important in order to avoid revision surgeries. Revision surgeries were performed safely in all cases, and significantly improved vocal outcomes were observed, even after multiple procedures. Revision surgery should be considered for patients with unsatisfactory vocal functions after primary framework surgeries for unilateral vocal fold paralysis.

Videostrobokymographic analysis of benign vocal fold lesions

OBJECTIVES: Videostrobokymography (VSK) has recently been introduced. The aim of this study was to analyze vibratory patterns and objective parameters in various benign vocal fold lesions using VSK and to examine the efficacy of VSK in clinical applications. MATERIAL AND METHODS: Using VSK, we analyzed the vibration patterns of normal vocal folds, various benign lesions such as nodules, polyps, cysts and Reinke's edema and cases of unilateral vocal fold paralysis. We also calculated the objective parameters open quotient and asymmetric index and compared them with their mean values in normal controls. RESULTS: In nodules, polyps and cysts, the open quotient at the site of the lesion was similar to the mean value in the normal controls; however, on the other parts of the vocal folds, it was much larger than the normal mean value. In Reinke's edema, irregular and asymmetric vibrations were observed. The posterior area of the vocal folds showed larger open quotients than the anterior area. In unilateral vocal fold paralysis, irregular vocal fold vibration and incomplete closure of the vocal folds were documented. Much larger asymmetric indices were calculated for unilateral vocal fold paralysis than in normal controls or for other lesions. The asymmetric index may be a good quantitative parameter of vibration in patients with vocal fold paralysis. CONCLUSION: This study demonstrated that VSK could generate clear quantitative documentation of fine vibrations of vocal folds in many different types of benign lesion. VSK has the potential to be an effective tool for the quantitative analysis of vibratory patterns of vocal folds in clinical settings.     

Transcutaneous intrafold injection for unilateral vocal fold paralysis: functional results

This paper presents the technique of transcutaneous intrafold silicone injection and the functional results of 44 procedures in 42 patients. The injection is given under local anesthesia with the patient in a supine position. The needle is inserted through the cricothyroid space. The location of the needle as well as the effect of injection is monitored by means of a fiberscope connected to a television camera and screen. The preoperative and postoperative vocal function was multidimensionally evaluated with the use of a test battery consisting of the maximum phonation time (MPT), mean airflow rate (MFRc), fundamental frequency (F0) range and sound pressure level (SPL) range of phonation, pitch perturbation quotient (PPQ), amplitude perturbation quotient (APQ), and normalized noise energy (NNEa). In the majority of the patients, MPT, F0 range, and SPL range increased and MFRc, PPQ, APQ, and NNEa decreased postoperatively. In the overall evaluation based on the test values of these parameters, the result was excellent for 16 procedures, good for 16, fair for 7, and poor for 5. The most frequent cause of failure was an insufficient amount injected.     

成人杓状软骨切除术前后声门测量及嗓音分析

OBJECTIVE: To study minimal glottic area which can acquire sufficient airway for decannulation and maximal glottic area which can maintain preoperative vocal function on adult bilateral vocal cord paralysis with unilateral arytenoidectomy. METHODS: Sixteen adult received microscopic right arytenoidectomy with Diomed-25 laser under general anaesthesia and sustained laryngoscope from September 1998 to February 2003. The pre-postoperative glottic measurement and vocal acoustic parameters were analyzed. RESULTS: The postoperative maximal glottic area, maximal posterior glottic width and maximal opening angle between bilateral vocal cords of the 15 decannulated cases were (45.93 +/- 6.56) mm2, (4.97 +/- 0.73) mm and (24.34 +/- 4.74) degrees respectively. Compared with preoperative period, there were significant difference. Pre-postoperative acoustic parameters (Jitter, Shimmer, harmonics-noise ratio) were analyzed and no significant difference were found (P > 0.05, but there are significant difference in NNE (normalized noise energy) and MPT (maximum phonation time) (P < 0.05). Except for three cases whose postoperative glottic area were more than 50. 1 mm2, there were no significant difference in pre and postoperative NNE (P > 0.05). The minimal glottic area decannulated was 38.0 mm2. The more opening maximal glottic area, the greater of NNE because of bigger closing gap. Noticeable increase of NNE was observed when maximal opening glottic area was up to 50.1 mm2. CONCLUSIONS: The minimal glottic area for decannulation should be 38.0 mm2, and the maximal glottic area for maintaining preoperation vocal function should be 50.1 mm2 on adult bilateral voca cord paralysis with laser aryntenoidectomy.

Transcutaneous intrafold injection result and its influencing factors

The result of transcutaneous intrafold injection and its influencing factors were studied for fifty five procedures in fifty two patients with unilateral recurrent nerve paralysis. Maximum phonation time, mean air flow rate and amplitude perturbation quotient of the voice were normalized or improved after the procedures more than 85%. In general assessment with functional and acoustic examinations, 76% of the procedures showed significant improvement. The paralysis after the thoracic surgery, right vocal fold paralysis and the paralysis complicated with sulcus vocalic tended to have insufficient improvement after injection. The most significant correlation to the result was shown in the degree of vocal fold augmentation immediately after injection. It was depend on the surgeon's technique and the patient's problems such as an anatomical abnormality of the larynx and an insufficient inhibition of the gag reflex.
