气管食管语言与食管语言的声学分析 总被引:1,自引:0,他引:1
《国外医学:耳鼻咽喉科学分册》1995,(5)
全喉切除术后恢复发育的两种最重要方法是食管语言与气管食管语言(应用低阻力瓣,Provox瓣)。两种再造喉语言的声振源是相同的,为咽食管段(PE段);但其发音动力不同,一种为由肺呼出的气体排出到咽,另一种是由食管排出的气体。众所周知,由于发音的强度大,持续时间长以及可理解性和可接受性强,气管食管语言较食管语言好。该文通过研究两种语言的声波和频谱,进行了详细的声学分析。病人分两组,均为男性,l组由12例食管发音良好者组成,另1组为12例应用Provox发音装置至少2个月的气管食管发音者。病人在适当大声和适宜时间发“a”… 相似文献

Vocal rehabilitation in laryngectomized patients can be attained by surgical (tracheoesophageal speech) or conservative methods (oesophageal speech or artificial larynx). We prospectively studied voice restoration in 37 patients who underwent total laryngectomy in the period from February 1991 to February 1993. The patients were given the opportunity to assess both non-shunt oesophageal speech and shunt oesophageal speech using the Provox voice prosthesis. The Provox low resistance, self-retaining voice prosthesis is a biflanged device made of silicon rubber. A primary tracheoesophageal puncture was made in 28 patients, while a secondary puncture was performed in another nine patients. The results were assessed according to criteria established at the ‘Third International Congress on Voice Prosthesis’ in Groningen (1988). Functional tracheoesophageal speech after primary puncture was achieved in 95% of patients 12 months after puncture, while oesophageal voice was acquired by 55%. Only minor surgical and prosthesis-related complications were encountered during this follow-up period in 29% of the patients. The device lifetime varied from 3 months to at least 2 years (mean 5.4 months). 相似文献

BACKGROUND: Indwelling voice prostheses are state of the art for post-laryngectomy voice rehabilitation. The aim of this study was to identify the impact of radiation prior to tracheoesophageal puncture on success rate and complications. PATIENTS AND METHODS: We undertook a retrospective study of 145 patients who had undergone prosthetic voice restoration between 1990 and 2002 (Provox) and Provox2). Risks of functional failure and complications in 17 patients with previous radiation therapy were compared to those of 128 patients without such therapy. RESULTS: Previous radiation increased not only the risk of functional failure by 2.9 (P=0.023), but also the risk of shunt-related complications such as aspiration around the prosthesis (1.51; P=0.046), widening of the shunt (2.32; P=0.014), esophageal (2.51; P=0.013) or tracheal (3.29; P=0.0023) dislocation of the prosthesis and spontaneous (2.51; P=0.047) or surgical closure (3.76; P=0.037) of the shunt. CONCLUSION: Primary tracheoesophageal puncture during laryngectomy is recommended in cases without previous radiation therapy, especially when post-laryngectomy radiation is likely. In patients with previous radiation therapy, generally good success rates decrease, however, without absolute contraindication of tracheoesophageal puncture. These results may affect salvage surgery concepts. 相似文献

Insertion of a voice prosthesis through the tracheoesophageal puncture (TEP) is one way to restore the voice after total laryngectomy. The second generation Provox voice prosthesis is presently one of the most popular devices. Although TEP can be done primarily, there are many centres that prefer it to be done at a second stage for various reasons. However, secondary TEP for retrograde replacement of prosthesis can be difficult and general anaesthesia is very often necessary. Moreover, the presence of neck stiffness and fibrosis from the surgery or previous radiotherapy could affect the neck extension for proper positioning of the trocar. Similarly, it is difficult to insert the prosthesis if there is stenosis at the pharyngoesophageal segment. We describe a technique in which creation of secondary TEP and insertion of Provox2 is done with local anaesthesia under the same setting. The procedure is well tolerated and can be safely performed on an out-patient basis. 相似文献

We describe the speech rehabilitation outcome of patients treated with total laryngectomy or total laryngopharyngectomy and insertion of Provox voice prostheses (Atos Medical AB, H?rby, Sweden) at the Helsinki University Central Hospital. We performed a retrospective chart review of 95 patients (88 men and 7 women; mean age, 63.5 years) who underwent insertion of a voice prosthesis in the period 1992 to 2002. Eighty-one percent (77/95) of the patients underwent a primary prosthesis insertion at the time of laryngectomy. A head and neck surgeon, a laryngologist, and a speech therapist rated the long-term tracheoesophageal speech of 78% (74/95) of the patients as good or average. The main causes for replacement of the device were obstruction, leakage or inadequate size of the prosthesis, and granulation or leakage around the fistula. According to our 10-year experience, use of the Provox prosthesis is an effective method of postlaryngectomy voice rehabilitation, and it continues to be our preferred method of voice restoration in the majority of cases. 相似文献

The first voice prosthesis was described in 1972 by Mozolewski. Eight years later Blom and Singer constructed the first commercial prosthesis. In 1988 another prosthesis was presented as Provox system prosthesis. The aim of the study was to describe the technique of tracheoesophageal puncture (TEP) and to present two years results of the technique performed in 21 patients. Primary TEP with immediate implantation of the Provox 2 prosthesis was applied in 16 (76%) patients. In five patients (24%) secondary TEP was performed. All the patient with primary TEP had cricopharyngeal myotomy. In 7 patients the vocal prosthesis was exchanged. In five because of leakage through the valve and in two patients the vocal prosthesis was extruded. Leakage around the prosthesis occurred in two patients with secondary TEP. The mean device-related lifetime was 216 days and ranged from 30 to 540 days. In non-radiated patients the lifetime of the prosthesis was 255 days and in patients after radiotherapy the lifetime was 150 days. In all the patients the prosthetic voice was more similar to normal voice than in patients with esophageal speech. The implantation of the voice prosthesis is a simple method of restoring of a good quality voice enabling communication. 相似文献

Postlaryngectomy speech rehabilitation more frequently includes surgical-prosthetic methods since the introduction of a low morbidity tracheoesophageal puncture technique and a one-way airflow valve. This study compares speech using an artificial larynx and, in one case, esophageal speech with speech using a tracheoesophageal puncture and valve in the same speaker. Using nonprofessional listeners, speech was rated for intelligibility and preference. Voice spectrograms were employed for measurement of rate, fundamental frequency, and intensity. While no statistically significant differences were found in mean fundamental frequency or intensity, the rate of post-tracheoesophageal speech was considerably faster. In addition, when individual speakers are compared with themselves, post-tracheoesophageal speech is significantly more intelligible and preferred by naive listeners. We conclude that using the tracheoesophageal puncture with valve should be strongly considered in total laryngectomy patients whose present mode of communication is unsatisfactory. 相似文献

Objectives: Compare the most commonly used types of tracheoesophageal voice prostheses, Blom Singer and Provox. Study Design: Prospective study of 113 prostheses placed in 52 patients randomly selected to receive Blom-Singer and Provox. Methods: Postoperative voice was recorded at 1 and 4 months after valve placement. Survival time of the prosthesis and four objective voice parameters were analyzed. Eight judges rated all recordings in a random order for six subjective voice parameters. Subgroup analysis for primary versus secondary placements and type of procedure was performed. In addition, patients were asked for their subjective assessment. Results: Overall, Blom-Singer and Provox prostheses give very similar voice quality, lifetime, and patient satisfaction. Cleaning management is somewhat better for Provox, but there is a trend toward better overall voice quality for the Blom-Singer prosthesis. In subgroup analysis secondarily placed prostheses score somewhat better than primary placements, and patients with total laryngectomy have better voices than patients with extended laryngectomy combined with partial pharyngectomy. Conclusions: Given the equal and good results in terms of voice quality, other factors (e.g., costs, surgery-related factors, maintenance, patient preference) should be taken into account when deciding which type of tracheoesophageal voice prosthesis to use.

The objectives of this study were to determine (1) the rates of complications, admissions to hospital and requirements for further surgery in patients fitted with tracheoesophageal fistula speech valves, and (2) whether any factors were predictive of complications. A case note review was undertaken of all patients undergoing a laryngectomy at Gartnavel General and Stobhill Hospitals over a 10-year period. One hundred patients were identified. Forty-five patients had complications from their valves, most commonly granulation tissue formation. Thirty-five had a least one admission related to complications and 34 required further surgery. Sixty-seven were vocalizing with the valve. Radiotherapy and valve type were not statistically significant in predicting complications in this study. Primary puncture was associated with a higher rate of complications, although the numbers undergoing secondary puncture were small. 相似文献

Secondary tracheoesophageal puncture (TEP) with voice prosthesis placement represents one of the possibility to restore vocal function after total laryngectomy. However, some patients have comorbidities that contraindicate general anesthesia. In our department, an in-clinic TEP procedure for retrograde voice prosthesis placement was developed. It allows the immediate placement of the prosthesis and the avoidance of the use of dilators. We described our technique with advantages and pitfalls. The Provox Vega Puncture Set was used. Our technique for in-clinic secondary TEP without general anesthesia or target controlled infusion was a safe and effective procedure. It allows the use of the traditional TEP set, with possibility of voice prosthesis placement after previous TEP closure. 相似文献

The study was made of the condition of voice prostheses Provox and Blom-Singer in 27 patients wearing them. The prostheses were to be replaced by new ones as they lost impermeability for water. The prostheses were used for 6 months to 2 years. At the prosthesis removal from the tracheoesophageal bypass it was found that the esophageal flange and protective valve were contaminated with fungi and pathogenic bacteria. The valve was deformed, had limited motility and did not close tightly the esophageal opening of the prosthesis as the result of which liquid leaked into the airways. Bacteriological examination identified C.albicans, C.krusei, C.glabralis in 11 patients. Nistatin, flucostat, fluconasol, amphotericin were used in antifungal therapy. Prophylactic use of these drugs against fungi prolonged use of the prostheses 2-fold. 相似文献
