Primary speech restoration at laryngectomy by insertion of voice prosthesis--10 years experience.

A total of 88 patients underwent laryngectomy at the ENT Department, Gentofte University Hospital, Hellerup, Denmark, from May 1989 to May 1999. Of these, 85 patients underwent salvage operations for squamous cell laryngeal carcinoma after previous full course radiotherapy. A total of 76 patients had primary tracheo-oesophageal puncture performed at the time of laryngectomy, 11 had a secondary procedure performed, 7 of these had been laryngectomized elsewhere. Eight patients were not eligible for tracheo-oesophageal puncture due to age, social reasons or extensive surgery. In all, 79 patients were able to use the prosthesis for communicative purposes weeks after the operation and developed fluent speech. During the observation time, 14 patients had their voice prosthesis removed or disconnected for various reasons. The average life duration for Provox voice prosthesis generation I vs Provox generation II was 3.1 and 2.3 months, respectively.

Perichondrial flap to prevent chondritis and cartilage necrosis in salvage vertical partial laryngectomy for recurrent glottic carcinoma after irradiation: a new procedure.

CONCLUSION: We conclude that our new closure method using the posterior- and inferior-based perichondrial flap may diminish the chance of development of chondritis in salvage vertical partial laryngectomized patients with recurrent glottic cancer. OBJECTIVE: Post-radiation laryngeal chondritis with resultant cartilage necrosis is one of the most dreaded complications of radiotherapy treatment of glottic carcinoma. In the case of salvage vertical partial laryngectomy, the risk of its development may be increased. We introduce a new posterior- and inferior-based perichondrial flap procedure to prevent postoperative chondritis after salvage vertical partial laryngectomy. MATERIAL AND METHODS: The perichondrium is incised along the midline and upper border of the thyroid cartilage, but not along the inferior border, unlike the conventional method. Then, the posterior- and inferior-based perichondrial flap, along with the cricothyroid muscle fascia, is elevated from the midline. For closure of the pharyngeal lumen, the outer perichondrium of the lesion side is sutured to the inner perichondrium of the contralateral side to protect the larynx from pharyngeal secretion. The utility of this procedure is reviewed retrospectively in 10 patients with locally persistent or recurrent squamous cell carcinoma of the vocal cord after failed laryngeal radiation therapy between 1994 and 2001. RESULTS: None of our patients developed chondritis postoperatively. The interval between the operation and removal of the tracheostomy tube ranged from 8 to 23 days (mean 12 days). Patients were able to swallow without aspiration within 7-22 days of the operation (mean 10 days). Discharge from hospital was possible after a mean recovery period of 11 postoperative days.

Difficulties in the fixation of prostheses for voice rehabilitation after laryngectomy.

In most patients with advanced or recurrent laryngeal or hypopharyngeal cancer, total laryngectomy is indicated. This means the loss of three main functions: phonation; respiration; and the prevention of aspiration during deglutition. Laryngectomy patients have various options to restore phonation: an oesophageal voice; an electrolaryngeal voice; or a tracheo-oesophageal voice. In the last case a silicone rubber shunt valve is placed in the tracheo-oesophageal wall and phonation is generated when exhaled air is forced through the oesophagus and neopharynx. This method is widely applied in Western Europe. In this paper we review the literature on fixation problems with shunt valves, tracheostoma valves and heat and moisture exchange (HME) filters. Tracheo-oesophageal speech without a valve is not considered. Despite 22 years of experience with the implantation of tracheo-esophageal shunt valves and many improvements in the design, problems still remain, such as biofilm formation with subsequent leakage through the valve, the need for frequent and inconvenient replacements, fistula enlargement leading to leakage around the device and reduced fixation, and infections. The high cost of shunt valves is a drawback to their use worldwide. To enable hands-free speech, different types of tracheostoma valve have been developed. These valves are fixed to the skin or to the tracheostoma by means of an intra-tracheal device. An HME filter is used to protect the airway and maintain physiological balance. Such devices are only suitable for a selected group of patients as fixation to the skin or trachea can be a major problem. Speaking and coughing cause pressure increases, which often result in mucous leakage and disconnection of the valve and/or HME filter. Recommendations are made for future improvements in fixation techniques.

Development and clinical assessment of a heat and moisture exchanger with a multi-magnet automatic tracheostoma valve (Provox FreeHands HME) for vocal and pulmonary rehabilitation after total laryngectomy.

OBJECTIVE: To develop and test the prototypes of a novel post-laryngectomy rehabilitation tool incorporating an obligatory, disposable heat and moisture exchanger (HME) and a reusable, multi-magnet automatic speaking valve (ASV). MATERIAL AND METHODS: The study subjects comprised 20 laryngectomized individuals (15 males, 5 females), 5 of whom were already using an ASV and 15 who were not. Three successive prototypes were tested. Data were collected by means of structured questionnaires, considering for example patient compliance, skin adhesion, voicing and coughing aspects, and voice and speech quality assessments, assessing for example maximum phonation time and dynamic loudness range. RESULTS: Of the 15 non-ASV users, 5 did not comply with the study due to peristomal skin adhesion problems. Of the remaining 15 patients, all 5 ASV users and 6/10 non-users were fully compliant with the new device. The cough-relief valve of the new device functions properly, as does the valve position adjustment for physical exertion. With this new device the maximum phonation time was longer than with a regular ASV (15.2 vs 11.6 s; p = 0.006) and the dynamic range was larger (33.0 vs 24.8 dB; p < 0.001). CONCLUSION: The test results obtained with this new device show that its advanced features (obligatory HME and multi-magnet valve systems) offer additional benefits for further improving vocal and pulmonary rehabilitation after total laryngectomy.

Speech and voice analysis after near-total laryngectomy and tracheoesophageal puncture with implantation of Provox 2 prosthesis.

Vocal characteristics were compared in two groups of patients who were operated on due to laryngeal cancer. One group was composed of patients after near-total laryngectomy and the other after total laryngectomy followed by tracheoesophageal puncture with implantation of Provox 2 prosthesis. Acoustic analysis was carried out using the EZ Voice Plus program and included the following parameters: fundamental frequency, jitter, shimmer, harmonic to noise ratio, range of fundamental frequency, maximal phonation time and intensity.

Social environment and adjustment after laryngectomy.

The relationship between social environmental variables and psychological, physical, and speech dysfunction after laryngectomy surgery was examined. The relationships between these categories of dysfunction and the following three social environmental factors were examined: (1) acceptance and emotional support from family and friends; (2) disease-specific support from peers who have had the same surgical intervention and from professionals; and (3) socioeconomic status (SES). Data were collected from 60 total laryngectomy patients an average of 24.3 months after surgery. The type of support provided was different for each source of support, family-friend or peer-professional. Interpersonal support from family and friends was strongly associated with psychosocial and physical dysfunction but had a weaker association with speech adjustment. Diseases-specific support from speech therapists and other laryngectomees was a weaker predictor of dysfunction but a stronger predictor of communication adaptation. SES was not predictive of dysfunction or communication adaptation. Thus different sources of social support can make specific contributions to minimizing physical and psychosocial dysfunction and acquiring skills to overcome the limitations imposed by the surgery.

Primary closure of pharyngeal remnant after total laryngectomy and partial pharyngectomy: how much residual mucosa is sufficient?

After total laryngectomy with or without partial pharyngectomy, the remaining pharyngeal defect can be repaired either by primary closure or with additional tissue, depending on the amount of pharyngeal tissue remnant available. The aim of this study was to determine the minimum width of the pharyngeal remnant that could be safely closed primarily without causing difficulty in swallowing. A total of 52 consecutive patients who underwent total laryngectomy were entered into the study. The relaxed and stretched widths of the pharyngeal remnant were measured after removal of the specimen. The widths of the pharyngeal mucosa ranged from 1.5 to 5.0 cm relaxed (mean, 3.24 cm) and from 2.5 to 8.0 cm stretched (mean, 4.83 cm). All neopharynx was reconstructed by closing the pharynx primarily. Seven of the 52 patients developed recurrent tumor with concomitant dysphagia. Two of the 45 patients without recurrence presented with acute dysphagia from food bolus obstruction, and 1 patient developed benign inflammatory stricture following an episode of fish-bone impaction. The narrowest widths of the pharyngeal remnant in this group of 45 were 1.5 cm relaxed and 2.5 cm stretched. As these patients do not have swallowing difficulty, we conclude that in the absence of tumor recurrence, this amount of residual pharyngeal tissue is sufficient both for primary closure of the pharynx and in restoring swallowing function.

Potential success of near-total laryngectomy despite postoperative radiation therapy.

Advanced laryngeal cancers frequently require total laryngectomy (TL). Some of these cancers, however, are suitable for near-total laryngectomy (NTL). We review our experience with NTL over a 14-year period and compare the functional results with those obtained over the same period using TL followed by tracheoesophageal puncture (TEP). One particular interest was the results achieved when surgery was preceded or followed by radiation therapy. From January 1980 through December 1994, 22 patients underwent NTL. The mean age of the 19 men (86.4%) and 3 women (13.6%) was 61.1 +/- 9.9 years. Follow-up ranged from 4 to 109 months, with a mean of 26.5 months. The local control rate was 90.9% (i.e., 20 of the 22 patients). Over the same time period, 11 TEPs were performed in 7 men (63.6%) and 4 women (36.4%) who had a mean age of 60.4 +/- 7.2 years. Compared with the TEP group, the patients in the NTL group had higher mean scores for swallowing, aspiration, and voice quality evaluations, although the differences were not statistically significant. Notably, 21 of 22 patients (95.5%) received preoperative or postoperative radiotherapy. Complications in the NTL group included aspiration, dilated shunt appendix, and inadequate tracheopharyngeal shunt function. Slight modifications of the NTL technique, including routine entrance into the vallecula in uninvolved larynges, the use of contralateral pyriform mucosa flaps, and the performance of an H-flap tracheostomy are described. The NTL is a sound oncologic procedure for tumors causing vocal cord fixation, and it can be successful even when postoperative radiotherapy is administered. The quality of speech, the ease of swallowing, and the incidence of aspiration are similar to those in patients who have had a TEP following TL.

A surgical technique to prevent tracheostomal stenosis after laryngectomy.

Tracheostomal stenosis after total laryngectomy is a frequently occurring nuisance to both the patient and the surgeon. Although many causes may contribute to the development of tracheostomal stenosis, operative technique seems to play a major role. The authors describe and explain their method of stomal construction. Over a 10-year period they have used the described method on 260 patients undergoing a total laryngectomy, with an incidence of tracheostomal stenosis of 6%.

Quality of life and voice in patients with laryngeal carcinoma: a posttreatment comparison of laryngectomy (salvage surgery) versus radiotherapy.

OBJECTIVES: This study was designed to compare the voice and the quality of life (QOL) of laryngeal cancer patients receiving treatment with radical radiotherapy with or without laryngectomy as salvage surgery. We also compared the patients' own perceptual ratings of their voice to the perceptual ratings of a group of listeners. STUDY DESIGN: Two groups of laryngeal cancer patients were studied. METHODS: Fourteen irradiated laryngeal speakers with preserved larynx were matched with 14 salvage surgery laryngectomized patients speaking with tracheoesophageal prosthesis (TEP). To measure patients' QOL, we used the European Organisation for Research and Treatment of Cancer Quality of Life Core Questionnaire (EORTC QLQ-C30), the EORTC Head and Neck module (EORTC QLQ-H&N35), the Hospital Anxiety and Depression scale (HAD) and a study-specific questionnaire. For the perceptual speech evaluation we used visual analog scales. RESULTS: The perceptual ratings of speech intelligibility, voice quality, and speech acceptability showed a significant difference between the treatment groups. Both the patients who received treatment with radiotherapy and the listeners rated the irradiated laryngeal voices higher than the tracheoesophageal speech. The laryngectomized patients scored significantly better than the patients treated with radical radiotherapy on the question about hoarseness. No other significant difference was found for the QOL functions and symptoms. CONCLUSION: When patients treated with radiotherapy were compared with patients treated with laryngectomy as salvage surgery, QOL was similar, only small differences being found in the perceptual speech evaluation.

Deterioration of olfaction and gustation as a consequence of total laryngectomy.

INTRODUCTION: After total laryngectomy the absence of a nasal airflow results in a decrease in olfaction and perception of flavors. MATERIALS AND METHODS: Odor perception was assessed in 63 laryngectomized patients with two different olfactory tests. The methods used by patients to smell were observed during olfactory testing. Patients' judgment about their olfaction and gustation was assessed by means of a structured questionnaire, semistructured interview, and self-rating. RESULTS: Based on the results of the olfactory tests, patients were categorized as "smellers" and "nonsmellers." Approximately one third of the patients were able to smell the odorous substances used in the olfactory tests. The smellers more often used a variety of methods to smell than the nonsmellers (P < .002); in most patients the method consisted of active use of facial muscles. Patients appeared well able to judge their own odor perception. Compared with the smellers, the nonsmellers judged their odor perception as worse (P < .003) and reported a more severe decrease in gustation after the operation (P < .033). The results of this study in laryngectomized patients confirm the interrelation between olfaction and gustation: the nonsmellers reported a poorer gustation and a more severe decrease in gustation and appetite than both the smellers and a reference group of elderly persons (P < .05). Patients who reported a deterioration of olfaction and gustation tended to experience negative consequences such as the inability to smell smoke, leaking gas, or agreeable odors. CONCLUSION: Olfaction and odor-related flavor sensation are seriously deteriorated after total laryngectomy.

Patterns of swallowing after supraglottic laryngectomy.

OBJECTIVE: To understand the anatomical and physiological basis for early recovery of swallowing function after supraglottic laryngectomy. STUDY DESIGN: Retrospective review. METHODS: The records of nine patients who had undergone supraglottic laryngectomy at the Stratton Veteran's Administration Hospital (Albany, NY) between 1994 and 1998 were reviewed. Videofluoroscopic swallowing studies were obtained on all patients as early as was safely possible and were reviewed by a multidisciplinary team of physicians, nurses, and speech pathologists with regard to anatomical and functional differences between successful and unsuccessful recovery of swallowing function. RESULTS: Five of nine patients resumed regular diets including thin liquids within 1 year of surgery; three patients remained dependent on enteral support. Swallowing success was most closely associated with short oropharyngeal transit time and an anterosuperior position of the larynx. Laryngeal positioning, tongue base mobility, and placement and coordination of the bolus for maximum swallowing efficiency can be improved with time and speech therapy. CONCLUSIONS: Factors that placed patients at significantly higher risk for aspiration included low laryngeal position and delayed oropharyngeal transit time. Tight lingual-laryngeal closure did not completely prevent aspiration. At the time of the initial surgical procedure it may be important to position the laryngeal remnant as far superior and anterior under the tongue base as possible.

Partial frontolateral laryngectomy with epiglottic reconstruction for management of early-stage glottic carcinoma.

OBJECTIVES: The aim of this study was to demonstrate that partial frontolateral laryngectomy with epiglottic reconstruction (PFLER) is an effective therapeutic option for treatment of T1 and T2 glottic carcinoma. STUDY DESIGN: Retrospective study. METHODS: Between 1982 and 1997, we treated 127 cases of early glottic carcinoma with PFLER. Early glottic carcinoma was staged using the Union Internationale Contre le Cancer TNM classification as either T1N0M0 (62 cases) or T2N0M0 (65 cases). Selection criteria, depending on the limits of exeresis, must remain glottic carcinoma with less than 0.5 cm of anterior subglottic involvement, with no involvement of the supraglottic space or laryngeal side of the epiglottis, with involvement of only one arytenoid, and with good mobility of both arytenoids even if vocal cord mobility is decreased. RESULTS: Postoperative recovery was uneventful in all cases, and all patients but one were able to breath and eat normally. The failure involved a patient with a permanent gastrostomy. As with other partial laryngectomy techniques, the main drawback of PFLER was deterioration of voice quality. All patients presented hoarseness and weakness of the voice. Five-year survival rates calculated according to the Kaplan-Meier method were 91% (standard error, 5%) in the T1N0M0 group and 86% (standard error, 5%) in the T2N0M0 group. No recurrence was observed in the T1N0M0 group. Local control was successful in 92% in the T2N0M0 group after a median follow-up of 5 years. CONCLUSION: These findings show that PFLER is an effective therapeutic option in selected cases of early T1N0M0 or T2N0M0 glottic carcinoma.

Near-total laryngectomy in advanced laryngeal and pyriform cancers.

OBJECTIVE: To demonstrate the oncologic and physiological safety of near-total laryngectomy (NTL), its success in voice conservation, and its versatility for use in extensive resections that necessitate pharyngoplasty, and even in post-radiation recurrences. STUDY: In this study of 137 cases of NTL for cancer of the larynx (45 cases) and pyriform (92 cases), 86.9% were stage T3/T4 and 60.6% were N+. A total of 8.8% had extended pharyngeal resections necessitating patch pharyngoplasty (ENTLP). In 10.9% cases, NTL was used as salvage of post-radiation failures. Concurrent neck dissection was performed in 99 cases. RESULTS: A total of 70.1% was alive and disease-free at the last follow-up ranging from 12 months to 104 months (median, 35 mo). A total of 7.3% had local/locoregional recurrences and 11.7% had purely regional recurrences. The local control rate for post-radiation salvage with NTL was 93.3%. A total of 88.6% developed communicable speech, and the speech success rate was 100% in 12 cases of ENTLP. Complications included major wound dehiscence with total shunt breakdown in 2 cases (1.5%), pharyngeal leak requiring surgical intervention in 7 cases (3.6%), significant aspiration through the shunt necessitating completion laryngectomy in 1 case (0.7%), and complete shunt stenosis in 9 cases (6.6%). CONCLUSION: The study shows that NTL is an oncologically safe voice conservation procedure in advanced, lateralized laryngeal and pyriform cancers treated not only per primum, but also in carefully selected post-radiation failures. It has a high success rate of speech development even in those cases requiring extensive pharyngeal resections. Major complications were acceptably low.

Total glossectomy without laryngectomy as first-line or salvage therapy.

OBJECTIVES/HYPOTHESIS: Advanced carcinoma of the tongue can require total glossectomy. Although radiation therapy is of limited efficacy in T3 and T4 tumors involving the base of the tongue, many surgeons are reluctant to suggest highly mutilating surgery. STUDY DESIGN: Retrospective cohort study. METHODS: We compared early postoperative complications, hospital stay duration, function, and oncological outcomes in patients who underwent total glossectomy without laryngectomy as first-line or salvage therapy. RESULTS: Postoperative course and functional outcomes were similar in the two groups. Overall survival was 32% at 3 years and 21% at 5 years. The risk factors for shorter survival were positive margins of resection (P =.002) and tumor spread into the mandible (P =.04). Salvage surgery was not associated with significantly lower survival (P =.09 [NS]). CONCLUSIONS: Postoperative morbidity and functional outcomes are similar after first-line and salvage total glossectomy without laryngectomy. Local tumor control is the main factor influencing survival.

Professor Nicolas Taptas (1871-1955): a pioneer of post-laryngectomy voice rehabilitation.

OBJECTIVE: To report on the career of Professor Nicolas Taptas of Constantinople (1871-1955) and his contribution to the development of an artificial larynx. STUDY DESIGN: Historical review. METHODS: The unpublished documents of Taptas's family archives and one of his papers, describing his own original technique for voice rehabilitation after total laryngectomies, were studied. RESULTS: In his texts, Taptas described the application of external laryngeal prostheses in one of his patients who underwent total laryngectomy. Taptas meticulously recorded his own first successful attempt in a woman with cancer of the larynx. He was one of the first scientists who, at the end of the 19th century, devised an external laryngeal prosthesis, which had the advantage of rehabilitating a sufficiently strong whispering voice; by using a prototype valve, he avoided problems of aspiration of liquids and food to the bronchi. CONCLUSION: Nicolas Taptas's contribution to the development of the artificial larynx was vital because he devised and applied one of the first external laryngeal artificial prostheses with satisfactory functional results.

Technique of en block laser endoscopic frontolateral laryngectomy for glottic cancer.

During the last 30 years, there has been expansion of the role of endoscopic partial laryngectomy procedures since Jako, Strong, and Vaughan explored the possibilities of CO2 laser microlaryngeal procedures. Despite the fact that a number of investigators have verified the validity of endolaryngeal laser resection of mid-sized glottic cancer, there are many who are unfamiliar with the technique and others who are uncomfortable with sectioning the tumor to facilitate its resection. In the past 3 years, 15 patients underwent successful en block resection of mid-sized glottic cancer (T1b 2, T2b 11, T3 2). Because en block resection is more consistent with open oncologic approaches, this method should widen the acceptance of this approach in selected lesions. The nuances of en block endoscopic frontolateral laryngectomy are presented with the hope that more surgeons will adopt this philosophy as an aspect of their armamentarium.

Endoscopic vertical partial laryngectomy.

OBJECTIVE: To explain the significant difference between microlaryngoscopy with cordectomy and endoscopic vertical partial laryngectomy (EVPL), to describe the efficacy of EVPL on T1b and T2 glottic squamous cell carcinoma, and to evaluate EVPL with postoperative irradiation in T2 glottic cancer with impaired true vocal cord mobility. STUDY DESIGN: Retrospective review. METHODS: Twenty-six patients seen at the University of Utah Health Science Center between 1987 and 2000 with bilateral T1 (T1b) or T2 squamous cell carcinoma of the glottic larynx underwent EVPL. T2 cancers were classified as follows: a = unilateral disease, b = bilateral disease; i = impaired mobility. T1b and T2a glottic cancer patients received surgery alone, whereas impaired mobility patients (T2ai + T2bi) patients received surgery followed by planned postoperative irradiation. Patients were assessed for primary site control, perioperative and long-term complications, and ultimate cancer control. RESULTS Survival in the total group was 88.5%, with local control at 92.3%. The two recurrent patients were salvaged by total laryngectomy. For the whole group, anterior commissure involvement was present in 57.7% (15 of 26). Thirteen T2 (5 T2ai + 8 T2bi) carcinoma patients underwent combined therapy, with 8 (61.5%) of these patients having anterior commissure involvement. Two of these patients were upstaged at surgery, one to T3 and one to T4. Local control was 84.5%. Thirteen patients were treated by surgery only, with five of these patients having failed previous irradiation. Survival was 92.3% and local control 100%. This group included two T2bi patients, two patients upstaged to T4 on the basis of extension beyond the subglottis to the anterior wall of the trachea, 3 T2b, and 6 T2a patients. Anterior commissure involvement was seen in 7 (53.8%) of these patients. CONCLUSIONS: EVPL alone controlled all T1b and T2a glottic cancer patients, even in the presence of greater than 50% anterior commissure involvement. The significant difference between EVPL and classical microlaryngoscopy with cordectomy was carefully described. EVPL with planned postoperative irradiation resulted in an 85% local control rate in clinically staged T2ai and T2bi cancer patients, including the three upstaged patients.
