OBJECTIVE: Since 1990, we have performed steroid injections into the vocal fold under topical anesthesia using fiberoptic laryngeal surgery (FLS) in an outpatient clinic. The aim of this study was to retrospectively assess the usefulness of this treatment method in 44 patients with mild Reinke's edema. MATERIAL AND METHODS: Using fiberoptic monitoring of the larynx, a curved injection needle was inserted via the oral cavity and triamcinolone acetonide was injected into Reinke's space of the bilateral vocal fold. RESULTS: Remission or improvement was observed in almost all patients in terms of both patients' self-rating of hoarseness and endoscopic vocal fold findings The maximum phonation time was a mean of 9.0 s before operation and 11.4 safter operation, and this increase was significant (p < 0.01). Voice pitch also improved, from 168 to 181 Hz, in female patients, and this increase was also significant (p < 0.05). CONCLUSION: Steroid injection is considered to be useful for treating mild Reinke's edema. 相似文献

Background The nosology of free‐edge vocal fold lesions remains imprecise. In particular, the lesion termed pseudocyst remains enigmatic, because its histology is poorly defined and because its etiology is unknown. We define pseudocyst as a discrete, unilateral, localized area of Reinke's edema (without a capsule), usually occurring at the midportion of the free‐edge striking zone. Objective To report the demographic and clinical findings, as well as discuss our diagnostic and therapeutic strategies, in patients with unilateral Reinke's edema or pseudocyst. Methodology All patients diagnosed with unilateral Reinke's edema or pseudocyst over a 2‐year period (1998–1999) were identified from the clinical database of the Center for Voice Disorders of Wake Forest University, Winston‐Salem, North Carolina. The record of each patient was retrospectively reviewed. Results Thirteen patients were identified, 12 of whom were female. The mean age was 36 years. Sixty‐nine percent (9 of 13) had unilateral pseudocyst and 31% (4 of 13) had unilateral Reinke's edema. All patients had documented vocal fold paresis on laryngeal electromyography. The 9 patients with pseudocyst underwent excision of their lesions; 7 had bilateral medialization laryngoplasties, 1 had lipoinjection, and 3 did not have surgical intervention. Significant improvement was noted postoperatively on a self‐administered glottal insufficiency (symptom) index (P <.001). Conclusion Unilateral Reinke's edema and localized Reinke's edema (pseudocyst) are distinct clinical entities, occurring most frequently in women in their fourth decade. The finding of unilateral Reinke's edema or pseudocyst should alert the clinician to the likelihood of vocal cord paresis. Surgical intervention with medialization laryngoplasty appears to be beneficial. 相似文献

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. 相似文献

Since 1990, we have performed steroid injection into the vocal fold by fiberoptic laryngeal surgery (FLS) under local anesthesia. In this study, the usefulness of this method was evaluated in 28 patients with vocal nodules. Under monitoring using a fiberoptic laryngoscope, a curved injection needle was inserted via the oral cavity and steroid was injected. Endoscopic findings showed that the vocal nodule had disappeared in 17 patients of the 27 patients and decreased in 10 after injection. The maximum phonation time was 10.9 s before operation and 13.9 s after operation, showing a significant increase (P<0.05), and the mean flow rate also showed a significant improvement (P<0.05). The patients self-rating concerning hoarseness demonstrated great improvement after injection. This technique can be performed under local anesthesia in combination with voice therapy on an outpatient basis, and it is considered to be useful for treating vocal nodules. 相似文献

Conclusions. Office-based 585 nm pulsed dye laser (PDL) surgery appeared to be safe and effective. It can be considered as a treatment option for office-based vocal polyp removal. Objectives. A 585 nm PDL has been introduced to photocoagulate vascular lesions of the superficial layer of the lamina propria in the vocal fold to treat laryngeal pathology including laryngeal papillomas, granulomas, leukoplakia, and Reinke's edema. This study investigated the efficacy and feasibility of PDL surgery for the treatment of vocal polyps, and evaluated the associated moribidity. Subjects and methods. Among 270 patients who underwent office-based PDL surgery under local anesthesia at the Yeson Voice Center, 75 patients with vocal polyps were evaluated. The mean follow-up period was 5.2 months (range 3–10 months). A retrospective analysis was performed on the postoperative perceptual and acoustic level and treatment outcome. Results. All patients who underwent PDL surgery had complete regression of their laryngeal lesion. The postoperative voice assessment including aerodynamic, acoustic, and perceptual parameters showed significant improvement. All patients tolerated the procedure without serious complications. 相似文献

Objective/Hypothesis: To describe the arrangement of collagen fibers in the superficial layer of the lamina propria of the vocal folds with Reinke' edema. Study Design: Cross sectional analysis of the lamina propria of the vocal folds with Reinke's edema (RE). Method: The picrosirius polarization method was used to study the arrangement of collagen fiber. Findings of collagen disarrangement were categorized semiquantitatively and correlated with RE severity, age, cigarette smoking and duration of dysphonia. Results: Analysis of 20 specimens of vocal folds with RE showed that the intertwined network of collagen fibers resembling a wicker‐basket normally observed in vocal folds was disarranged in RE. The collagen fibers were loosely arranged, fragmented and intermixed with varying amounts of myxoid stroma. Moderate and large areas of disarrangement (90% of cases) predominated. Collagen fiber arrangement in the region underneath the epithelium was better preserved when compared with fibers in the deeper region of the superficial layer of the lamina propria. There was a statistical difference in collagen disarrangement between grade II and grade III severity (P = .007) that appeared to be due to the large areas of disarrangement observed in 73% of patients with grade III severity and in 44% of grade II severity. Age was the only variable correlated with collagen fiber disarrangement (r = 0.47, P = .037). Conclusion: Our findings suggest that the flexible framework which maintains the uniformity of the lamina propria was lost in RE caused by the disarrangement of the collagen fibers. 相似文献

Conclusion. Vocal fold vibration (phonation) after birth is one of the important factors in the growth and development of the human vocal fold mucosa. Objectives. Stellate cells in the maculae flavae located at both ends of the vocal fold mucosa are inferred to be involved in the metabolism of extracellular matrices. Maculae flavae are also considered to be an important structure in the growth and development of the human vocal fold mucosa. Tension caused by phonation (vocal fold vibration) is hypothesized to stimulate stellate cells to accelerate production of extracellular matrices. Vocal fold mucosae unphonated since birth were investigated histologically. Subjects and methods. Vocal fold mucosae, which were unphonated since birth, of three younger adults (17, 24, 28 years old) were investigated by light and electron microscopy. Results. Vocal fold mucosae were hypoplastic and rudimentary and did not have a vocal ligament, Reinke's space or a layered structure. The lamina propria appeared as a uniform structure. Some stellate cells in the maculae flavae showed degeneration. Not many vesicles were present at the periphery of the cytoplasm. The stellate cells synthesized fewer extracellular matrices, such as fibrous protein and glycosaminoglycan. Cytoplasmic processes of the stellate cells were short and shrinking. The stellate cells appeared to have decreased activity. 相似文献

Objectives Autogenous fat augmentation has been used as a treatment for glottic insufficiency. However, no information is available on the effectiveness of fat injection in patients with vocal nodules or recurrent vocal nodules after surgery. Study Design The retrospective study reviews the efficiency of fat injection after surgery in patients with vocal nodules (n = 18) and recurrent vocal nodules (n = 5). Methods The perceptual acoustic, phonatory function, and video laryngostroboscopic data were evaluated before and after surgery in 23 patients. Results Mean follow‐up time was 7.5 months. Nineteen patients had excellent results. Two patients had improvement, and no change was observed in two patients. Phonatory function showed significant improvement in shimmer, harmonic‐to‐noiseratio (P <.05), maximum phonation time, grade, roughness, and breathiness (P <.001). Video laryngostroboscopic rating showed significant improvement in linearity of the vocal fold edge, amplitude of vocal fold vibration, and excursion of the mucosal wave (P <.001). Less improvement was observed in recurrent vocal nodules than in nonrecurrent vocal nodules. Conclusions Fat injection is an effective autogenous implant and may be considered as an option in management of patients with vocal nodules after surgery. Recurrence of nodules is a problem, but the procedure may be repeated. 相似文献

ObjectivesThere are emerging reports of the effectiveness of in-office awake vocal-fold corticosteroid injection in the treatment of exudative vocal-fold lesions. The aim of this study was to review this therapy and specify indications, practical modalities and outcomes.Study designSystematic review of the literature without meta-analysis.MethodsA systematic review by PubMed search for the period January 2000 to December 2018 was carried out.ResultsNine articles were included, for a total of 502 lesions: nodules (46.4%), polyps (31.7%), and Reinke's edema (21.9%). Submucosal injection of low-dose triamcinolone acetonide (0.1 to 0.3 mL) was transoral, transcutaneous or transnasal via flexible endoscope with operating channel. Lesion volume was significantly reduced in more than 90% of cases, with significant vocal improvement in all studies. Relapse rates ranged between 4% and 31%, with time to relapse of 1 to 40 months.ConclusionsFirst-line treatment of exudative glottic lesions by submucosal corticosteroid injection provides at least transient significant reduction in lesion volume and vocal improvement. It is consensually reserved to moderate-sized mainly exudative lesions without fibrosis. In-office injection provides an immediate therapeutic response in case of vocal impairment, enabling surgery under general anesthesia to be postponed. 相似文献

Laryngeal/voice function was evaluated in six patients with unilateral true vocal fold paralysis following treatment with Teflon® injection (TEF) compared to six patients treated with thyroplasty type I (THY). Auditory perceptual, aerodynamic, and endoscopic assessments were conducted. Three judges rated nine voice characteristics. Aerodynamic measures included estimated subglottal pressure, airflow, and laryngeal resistance. Two judges rated laryngeal characteristics from flexible fiberoptic assessment. The THY group had significantly better voice quality and better quantitative aerodynamic findings compared to the TEF group. The TEF group also was more likely to have an irregular vocal fold edge, an irregular glottal closure pattern, a higher occurrence of hyperfunction and hypertrophy of the false vocal folds, edema, and erythema of the paralyzed folds. Results suggest that THY was associated with more favorable measures of laryngeal/voice function than TEF. It is likely that the poorer perceptual, aerodynamic, and endoscopic findings associated with TEF injection may be due to violation of the true vocal fold cover, particularly increased true vocal fold mass and stiffness. 相似文献

The status of the cricothyroid muscle, which is innervated by the superior laryngeal nerve, is believed to influence the vocal fold position in laryngeal paralysis. It is believed that isolated lesions of the recurrent laryngeal nerve generally result in the paralyzed vocal fold assuming a paramedian position but that with lesions of both the superior and recurrent laryngeal nerves, a more lateral (intermediate or cadaveric) vocal fold position can be expected. Twenty-six consecutive patients with unilateral vocal fold paralysis underwent transnasal fiberoptic laryngoscopy (TFL) and laryngeal electromyography (LEMG). By TFL, the vocal fold positions were paramedian in 8 patients, intermediate in 7, and lateral in 11. By LEMG, 13 patients had isolated recurrent laryngeal nerve lesions and 13 patients had combined (superior and recurrent laryngeal nerve) lesions. There was no correlation between the vocal fold position and the status of the cricothyroid muscle, i.e., the status of the cricothyroid muscle by LEMG did not predict the vocal fold position nor did the vocal fold position by TFL predict the site of lesion. In addition, we investigated the possibility that the degree of thyroarytenoid muscle recruitment (tone) might correlate with vocal fold position, but no relation was found. We conclude that 1. the cricothyroid muscle does not predictably influence the position of the vocal fold in unilateral paralysis; 2. thyroarytenoid muscle recruitment (tone) does not appear to influence vocal fold position; and 3. still unidentified and unknown factors may be responsible for determining vocal fold position in laryngeal paralysis. 相似文献

Vocal fold augmentation by injection under direct visual control is a quick and simple operation. However, when autologous fat or bovine collagen is used, resorption creates a problem. The low metabolic requirements and the relatively stable histologic character of free fascial grafts make autologous fascia a fascinating material in vocal fold augmentation. This research project was carried out to establish a suitable method to transplant fascia into a vocal fold and to assess its impact on the voice. A piece of fascia lata was chopped with a scalpel. The material was injected in the lateral aspect of the thyroarytenoid muscle using a pressure syringe. Nine subjects with a paralyzed vocal fold were analyzed after the injection. The postoperative voice, rated by a panel of experienced listeners, was significantly better than the preoperative ( P < 0.05). Five of nine voices were rated normal or near normal after the procedure. The mean maximal phonation time increased significantly ( P < 0.01). All patients considered that their voice had improved, and eight of nine regarded it as good. No one reported deterioration of the result during the follow-up (mean duration, 10 months; range, 3 to 18 months). 相似文献

AbstractConclusions. The scarring model resulted in significant damage and elevated viscoelasticity of the lamina propria. Hyaluronan preparations may alter viscoelasticity in scarred rabbit vocal folds. Objectives. Vocal fold scarring results in stiffness of the lamina propria and severe voice problems. The aims of this study were to examine the degree of scarring achieved in the experiment and to measure the viscoelastic properties after injection of hyaluronan in rabbit vocal folds. Materials and methods. Twenty-two vocal folds from 15 New Zealand rabbits were scarred, 8 vocal folds were controls. After 8 weeks 12 of the scarred vocal folds received injections with 2 types of cross-linked hyaluronan products and 10 scarred folds were injected with saline. After 11 more weeks the animals were sacrificed. After dissection, 15 vocal folds were frozen for viscoelastic measurements, whereas 14 vocal folds were prepared and stained. Measurements were made of the lamina propria thickness. Viscoelasticity was measured on intact vocal folds with a linear skin rheometer (LSR) adapted to laryngeal measurements. Results. Measurements on the digitized slides showed a thickened lamina propria in the scarred samples as compared with the normal vocal folds (p <0.05). The viscoelastic analysis showed a tendency to stiffening of the scarred vocal folds as compared with the normal controls (p =0.05). There was large variation in stiffness between the two injected hyaluronan products. 相似文献

Arachidonic acid metabolites (AAm) have important regulatory functions within several areas of otorhinolaryngology: modulation of immune and allergic responses, inflammation, allergy, etc. The aetiology of vocal fold polyps is still obscure as are the possible mechanisms responsible for their forming and developing. The aim of this study was therefore to investigate the relationship between release of prostaglandins (PGE2, PGI2) and tromboxans (TxA2) from vocal fold polyps ex vivo in 21 patients, in comparison to normal airway mucosa. The production of PGE2 by vocal fold polyps was less than in the controls (ng/ml) (0.5 ±0.54; n = 21 vs. 1.09 ± 0.78; n = 21) (p<0.05) but higher than in nasal polyps (0.14 ± 0.11; n=16) (p<0.01). Prostacyclin production by vocal fold polyps (0.99±0.92) was less than in control mucosa (2.24±1.93) (p<0.01), but higher than by nasal polyps (0.26±0.14) and less than in controls (0.99±0.73) (p <0.01) or nasal polyps (0.52±0.04) (p<0.01). 相似文献

ObjectivesThe human adult vocal fold mucosa, especially, superficial layer of the lamina propria (Reinke's space) has attracted notice as an important vibrating structure. However, fine structures of the stratified squamous epithelium of the human adult vocal fold, which is another histological component of the mucosa, remain enigmatic.MethodsThree normal human adult vocal folds and epiglottises and three newborn vocal folds were investigated. Observations using transmission electron microscopy and light microscopy including immunohistochemistry were performed.ResultsThe most obvious feature of the epithelium of the human adult vocal folds was that the intercellular spaces between adjacent epithelial cells were large (984 ± 186 nm) compared with the stratified squamous epithelium of the human adult epiglottis and the human newborn vocal fold.Even though intercellular spaces between adjacent epithelial cells of the human adult vocal fold were large, desmosomes at the junctions of two adjacent epithelial cells made firm intercellular adhesion. Tonofilaments composed of the bundles of intermediate filaments anchored to the desmosomes. Desmosomes formed a continuous cytoskeletal network throughout the epithelial cells and epithelium of the human adult vocal fold. In addition, a great deal of E-cadherin (adhesive glycoprotein) was present between epithelial cells especially the lower half of the stratified squamous epithelium of the human adult vocal fold.ConclusionsFrom the functional morphological point of view, stratified squamous epithelium of the human adult vocal fold seems to form a structural framework of tensile strength with pliability suitable structure for vibration. 相似文献

Objectives—To evaluate the long-term (24 months) clinical performance (vocal fold function) and safety of hylan B gel as compared with bovine cross-linked collagen in the treatment of patients with glottal insufficiency. Material and Methods—In a prospective trial, 70 patients with glottal insufficiency due to unilateral vocal fold paresis (n=35) or atrophy (n=35) were randomized to received either hylan B gel (n=47) or collagen (n=23) injections into 1 vocal fold. Forty-two of the patients were examined 24 months after treatment. Evaluations were made based on patients’ subjective ratings, digitized videostroboscopic measurements, maximum phonation time and phonation quotient. Results—The patients’ self-ratings were significantly improved in both the hylan B gel and collagen groups. Videostroboscopic measurements of glottal closure were significantly improved for both groups. The hylan B gel group showed a trend towards less resorption at the injected vocal fold edge in comparison with the collagen group (p=0.05). No serious adverse events were observed. Twenty-eight patients dropped out of the study after 12 months: 18 had been re-injected or operated on with medialization laryngoplasty due to insufficient voice and 10 had either died of causes unrelated to the study or refused to attend follow-up. Conclusions—No long-term side-effects were found for either the hylan B gel or collagen groups after injection treatment. Both treatments resulted in significantly improved voice as rated by the patients and significantly improved glottal closure. Some resorption was noted for both substances, and ≈25% of the patients chose re-treatment 2 years after the initial treatment. 相似文献

Objective
To evaluate through a multidimensional protocol voice changes after voice therapy in patients with benign vocal fold lesions.Methods
65 consecutive patients affected by benign vocal fold lesions were enrolled. Depending on videolaryngostroboscopy the patients were divided into 3 groups: 23 patients with Reinke's oedema, 22 patients with vocal fold cysts and 20 patients with gelatinous polyp. Each subject received 10 voice therapy sessions and was evaluated, before and after voice therapy, through a multidimensional protocol including videolaryngostroboscopy, perception, acoustics, aerodynamics and self-rating by the patient. Data were compared using Wilcoxon signed-rank test. Kruskal–Wallis test was used to analyse the mean variation difference between the three groups of patients. Mann–Whitney test was used for post hoc analysis.Results
Only in 11 cases videolaryngostroboscopy revealed an improvement of the initial pathology. However a significant improvement was observed in perceptual, acoustic and self-assessment ratings in the 3 groups of patients. In particular the parameters of G, R and A of the GIRBAS scale, and the noise to harmonic ratio, Jitter and shimmer scores improved after rehabilitation. A significant improvement of all the parameters of Voice Handicap Index after rehabilitation treatment was found. No significant difference among the three groups of patients was visible, except for self-assessment ratings.Conclusion
Voice therapy may provide a significant improvement in perceptual, acoustic and self-assessed voice quality in patients with benign glottal lesions. Utilization of voice therapy may allow some patients to avoid surgical intervention. 相似文献18.
Vocal fold augmentation by injection laryngoplasty is a simple and fast procedure. The aim of this prospective study was to assess the glottal closure and the travelling mucosal wave by videostroboscopic images after autologous fascia augmentation in unilateral vocal fold paralysis (UVFP) with a special reference to objective analysis of voice. A total of 14 UVFP patients with poor voice and open glottal gap were assessed by videostroboscopy, blinded perceptual evaluation of running speech and acoustical analysis of sustained vowel. Data were collected before the procedure and at a supplementary evaluation 5–32 months (mean: 13 months) after injection of autologous fascia deep into the paralysed vocal fold. Mean age was 59 years; there were eight women and six men. Frame-by-frame video analysis revealed that before the operation 10 out of 12 had large glottal gaps without any contact between vocal folds on phonation. After the procedure seven gaps were completely closed, four partly, and two had no mucosal contact in stroboscopic examination. Maximum gap between vocal folds decreased from 7.21 units to 1.65 units (paired t-test P<0.001). Mucosal wave amplitude symmetry and phase synchrony were present in most subjects with partial closure and phase synchrony in every patient with a proper glottic closure. A panel of listeners rated voice to be significantly better (P<0.01) ) after the procedure, and the improvement in acoustical parameters was also statistically significant (P<0.01). There was a good correlation between objective voice analysis and videostroboscopy. Residual glottal gap was the major reason for less than optimal postoperative voice. No signs of hampered mucosal wave were noticed. Videostroboscopy and objective voice analysis suggest that augmentation by autologous fascia does not induce scar or fibrous tissue in the subepithelial space. Slight over-correction should be attempted initially in order to accomplish sufficient augmentation. This might enhance complete glottic closure and improve the outcome. 相似文献

Objectives: This paper reviews a 12-year experience in more than 900 patients with spasmodic dysphonia who have been treated with botulinum toxin. Study Design: This is a retrospective analysis of patients with adductor spasmodic dysphonia (strainstrangled voice), abductor spasmodic dysphonia (whispering voice), and adductor breathing dystonia (paradoxical vocal fold motion), all of whom have been treated with botulinum toxin injections for relief of symptom. Methods: All of the patients were studied with a complete head and neck and neurologic examination; fiberoptic laryngostroboscopy; acoustic and aerodynamic measures; and a speech evaluation including the Universal spasmodic dysphonia rating scale. Some were given electromyography. All patients received botulinum toxin injections into the affected muscles under electromyographic guidance. Results: The adductor patients had an average benefit of 90% of normal function lasting an average of 15.1 weeks. The abductor patients had an average benefit of 66.7% of normal function lasting an average of 10.5 weeks. Adverse effects included mild breathiness and coughing on fluids in the adductor patients, and mild stridor in a few of the abductor patients. Conclusion: Botulinum toxin A injection of the laryngeal hyperfunctional muscles has been found over the past 12 years to be the treatment of choice to control the dystonic symptoms in most patients with spasmodic dysphonia.
