[Outcome of the treatment for laryngeal carcinoma by partial laryngectomies].

The aim of the study was to retrospectively evaluate the results of treatment for early laryngeal carcinoma in a group of 325 patients who underwent from 1980 to 1997 partial laryngectomies. The most often type of operation was cordectomy--51.1%, then frontolateral/frontoanterior laryngectomy--20.9%, vertical laryngectomy--15.1%, supraglottic horizontal laryngectomy--8%, hemilaryngectomy--4.9%. Estimate of survival time, from surgery to first oncologic failure, was obtained with the life-table method. As a failure we considered local and regional recurrence, distant metastasis, second primary neoplasm and spread of disease. The probability of disease-free survival for all partial laryngectomies reached 81.5%, 79.5% and 60.3% at 3, 5 and over 5 years, respectively. The rates of five-year and over 5 year disease-free survival for each type of operation were: for cordectomy--82.3% and 72.3%, for frontolateral/frontoanterior laryngectomy--74.0% and 45.2%, for vertical laryngectomy--87.6% and 60.6%, for hemilaryngectomy--86.2% and 59.7%, for supraglottic horizontal laryngectomy--53.8% and 29.9%, respectively. The comparison between survival rates, by the log-rank test, revealed statistical difference between supraglottic horizontal laryngectomy and following operations: cordectomy (p < 0.001), vertical laryngectomy (p < 0.01), hemilaryngectomy (p < 0.05). The differences between other types of laryngectomy were not significant statistically. The best results in treatment of laryngeal carcinoma by partial laryngectomies were achieved by operations in vertical plane (cordectomy, vertical laryngectomy and hemilaryngectomy), the less positive--by operations in horizontal plane (supraglottic horizontal laryngectomy).

[Study on vibration mode of different phonatory source and compensation after partial laryngectomy].

OBJECTIVE: To investigate the nature of pathological voice production and compensatory mechanism after partial laryngectomy. METHODS: Vocal function of 93 cases following partial laryngectomy (28 cases of horizontal partial laryngectomy, 35 vertical partial laryngectomy, 30 horizontal-vertical partial laryngectomy) were examined by acoustic analysis, aerodynamic analysis and videostroboscopic examination. RESULTS: Horizontal supraglottic laryngectomy(HL) resulted in slight dysphonia after operation. The cover of vocal fold was hypertrophic and edematous. Mucosa wave was increased. Acoustic analysis showed significant difference between normal and horizontal laryngectomy groups(P < 0.05). Vertical laryngectomy(VL) resulted in moderate-severe dysphonia. Acoustic analysis was significantly worse in VL than in normal group(P < 0.01). The nonglottic phonatory source was the contralateral ventricular fold or contralateral vestibular mucosa (arytenoid mucosa, root mucosa of glottis) to approximate the reconstructed flap. It was noted that contralateral vocal fold did not participate in vibration. Horizontal-vertical partial laryngectomy (HVL) resulted in moderate-severe dysphonia. Acoustic analysis of HVL was significantly worse than that of normal phonation(P < 0.01). The site of compensatory mucosa vibration upon phonation was the contralateral vocal fold or contralateral hypertrophic arytenoid mucosa. The thinner the flap, the better the vocal quality was. Vocal quality of VL was worse than that of HVL in regard to shimmer, jitter, normalized noise energy, maximal phonation time and harmonic-noise ratio, but there was no significant difference between them. CONCLUSIONS: Partial laryngectomy has different vibrating compensatory modes: Voice function of horizontal partial laryngectomy was the best as it preserved the normal vibration mode; vertical partial laryngectomy was the worst with the nonglottic vibrating source of reconstructed flap-ventricular fold. The reconstructed flap, ventricular fold, mucosa of epiglottis and arytenoid take predominantly part in neoglottal vibration. The situation, volume and pliability characteristic of reconstructed flap was also important to vocal quality.

[Partial laryngectomy for ninety-eight patients with glottic carcinoma of the larynx].

OBJECTIVE: To investigate the therapeutic results after various kinds of partial laryngectomy for patients with glottic carcinoma of the larynx. METHODS: From January 1980 to Mar 2004, 98 patients with glottic carcinoma of the larynx were treated by various kinds of partial laryngectomy. The types of operation varied according to stage of the lesion: vertical or frontovertical partial laryngectomy for T1b, T2 and T1a with invasion of anterior commissura, Tuker's operation or supracricoid partial laryngectomy for T1b, T2 or those with invasion of over half of contralateral cord, and extended vertical partial laryngectomy with resection of arytenoids for T3, or with invasion of ipsilateral arytenoids cartilage without involving postcricoid mucosa or posterior commissura. Totally, vertical partial laryngectomy was carried out for 76 patients, extended vertical partial laryngectomy for 7, supracricoid partial laryngectomy for 3 and Tucker's operation for 12. One stage unilateral neck dissection was performed in 5 patients and postoperative radio-therapy was supplemented to 5 (dose 60 Gy). For laryngeal function restoration, pectoro-hyomyo-flap and cricohyoidoepi glotopexy procedures were also performed for some patients. The clinical data of these patients were retrospectively analyzed. RESULTS: The 3- and 5-year survival rate was 86.5% (64/74) and 81.7% (49/60), respectively. The total decannulation rate was 94.9% (93/98), though fifteen patients had had symptoms of aspiration. Swallowing function of all patients recovered to the normal level. The phonation of all patients was restored to various degrees and they were able to communicate socially. CONCLUSION: The 3- and 5-year survival rates of partial laryngectomy for patients with glottic carcinoma of the larynx are comparable to the results achieved by total laryngectomy, but the quality of life of the patents much better. Complete resection of the tumor and simultaneous preservation of respiratory and vocal function whenever possible by partial laryngectomy is very important for improving patients' life quality. With a suitable size and good blood supply, the sternohyoid muscle flap of unipedical and half-thickness instead of whole thickness is ideal in the reconstruction of laryngeal defect after vertical partial laryngectomy.

Partial laryngectomy after irradiation failure.

INTRODUCTION: Radiation therapy is often the first method of treating patients with early cancer of the glottis. There is a substantial failure rate among these patients. Total laryngectomy has usually been the means of treating patients with failure after radiation. In recent decades, partial laryngectomy has been used for salvage in such patients. This article will discuss the use of partial laryngectomy for radiation failure both from the oncologic result as well as the morbidity. PATIENTS AND METHODS: Between 1984 and 1995, 27 patients with early-stage laryngeal carcinoma underwent salvage partial laryngectomy after irradiation failure. Vertical laryngectomy was performed in 18 patients (13 with T1 N0 and 5 with T2 N0) and horizontal-supraglottic laryngectomy in 9 patients (3 with T1 N0, 1 with T2 N0, and 5 with T2 N1). The mean follow-up was 4.1 years. RESULTS: Local control was obtained in 77.7% of patients with glottic lesions (T1: 84.6%; T2: 60%, P = NS) and in 55.5% of patients with supraglottic lesions (T1: 66.6%; T2: 50%; P = NS). There was no regional recurrence in the vertical laryngectomy group, whereas the regional control rate in the horizontal-supraglottic laryngectomy group was 77.7%. Distant control was achieved in 94.4% of patients with glottic disease and in 77.7% of patients with supraglottic disease. The overall survival rate for glottic lesions was 88.8% (T1: 92.3%; T2: 80%; P = NS) versus 66.6% for supraglottic lesions (T1: 100%; T2: 50%; P = NS). CONCLUSION AND SIGNIFICANCE: Vertical laryngectomy was not associated with an increased complication rate. Morbidity in the horizontal-supraglottic laryngectomy group was higher, but a satisfactory functional outcome was obtained in all cases. Therefore, in early laryngeal cancer (glottic T1-T2, supraglottic T1) partial laryngectomy can be performed with good expectation of cure and satisfactory laryngeal function. In T2 supraglottic lesions, the oncologic results are less satisfactory; further research is required for developing more efficient complimentary or alternative treatments modalities.

Educational needs and altered eating habits following a total laryngectomy.

PURPOSE/OBJECTIVES: To describe eating-related experiences and informational needs of people following total laryngectomies. DESIGN: Descriptive study. SETTING: Internet-based laryngectomy support group in the United States. SAMPLE: 34 people with a laryngectomy (68% total laryngectomy, 29% with total plus radical neck dissection, and 3% with partial laryngectomy with radical neck dissection): 29 males, 5 females; mean age of 62 years. METHODS: Members of a laryngectomy support group completed a Food Eating Experiences and Diet Questionnaire designed by the investigators. Both quantitative and qualitative data were collected. MAIN RESEARCH VARIABLES: Effect of laryngectomy on food choice, eating habits, and overall enjoyment of eating: perceptions of teaching received from healthcare professionals regarding potential eating difficulties as a result of laryngectomy. FINDINGS: 90% of the participants experienced a change in one or more aspects of eating. The most prominent changes were decreased sense of smell, decreased taste, decreased enjoyment of eating, and an increase in the length of time required to eat meals. Most participants were not satisfied with the information they received from healthcare professionals. Topics requiring emphasis during patient teaching were identified from participants' comments. CONCLUSIONS: Total laryngectomy produced significant changes in factors related to eating that can affect nutritional intake and quality of life. Participants reported that most healthcare providers did not adequately prepare them for potential alterations in eating that can occur following a total laryngectomy. IMPLICATIONS FOR NURSING PRACTICE: Data from this study can be used to raise awareness of incidence and severity of changes in eating that occur after total laryngectomy and to improve patient preparation to cope with these changes.

[The long term results of partial laryngectomy].

OBJECTIVE: To evaluate the long-term results of various kinds of partial laryngectomy. METHOD: The following-up materials from 264 patients who had undergone partial laryngectomy in this department from 3,1984 to 3,1998 wert analyzed. The pathological diagnosis of all the cases was squamous cell carcinoma. The surgical technique were divided into eight kinds: 1. laser vocal cord ectomy for 19 cases, 2. vocal cordectomy through laryngofissure for 29, 3. laterovertical partial laryngectomy for 58, 4. frontovertical partial laryngectomy for 18, 5. suproglottic partial laryngectomy for 42, 6.vertical-horizontal partial laryngectomy for 29, 7. extended subtotal laryngectomy for 51(extended to the base of tongue 23, to pyriform recess 25, to trachea 3), 8. subtotal laryngectomy for 18 (including 3 cases of middle segment partial laryngectomy and hypopharynx-trachea anastomasis). One hundred thirteen cases (146 sides) received neck dissection simuteniously. The materials that were used to reconstruct the operative defect simply or in combination included cervical myocuteneous flap, cervical myofascia flap, false cord, local laryngeal mucosa, thyroid perchondrium and epiglottis. RESULT: All the patients restored the function of phonation. No aspiration happened in 89 cases,mild aspiration in 112,moderate in 57 and severe in 6 cases. But the aspiration disappeared after a certain time of practice and the swallowing function restored in all patients. The rate of decannulation was 82.95%. The survival rate of 3-year,5-year and 10-year was 86.74% ,78.47% and 53.33%, respectively. The main causes of death were local recurrence and lymphatic metastasis, and 71.4 percent of the death happened in the first 3 years. CONCLUSION: The partial laryngectomy was a racial surgery as the same as total laryngectomy. The key point to success was to apply the operative indication strictly. And the important landmark of the patients' survival quality was the decannulation rate and the restoration of laryngeal functions. Correct management on cervical lymphatic nodes could raise the 3-year and 5-year survival rate.

[Extended supra glottic laryngectomies].

In the period 1976-1998, 408 patients with supraglottic laryngeal cancer were primarily treated by surgery using the method of supraglottic laryngectomy. Classical supraglottic laryngectomy was performed in 355 patients, while 53 underwent extended supraglottic laryngectomy. The objective of the study was to analyze the success of the extended supraglottic laryngectomy in relation to classical supraglottic laryngectomy in indicated cases. T1 tumor was found in 171 (42%) patients, T2 in 212 (52%), while T3 was found in 25 (6%) cases. Local recurrence developed in 3 out of 53 patients operated by the extended supraglottic laryngectomy technique, and in 17 out of 355 operated by classical supraglottic laryngectomy (chi2=0.075, DF=1, p=0.784; Yates=0.00, p=1.00). Five-year survival of patients operated by the extended supraglottic laryngectomy was reported in 40 out of 53 patients, while survival of patients operated by classical supraglottic laryngectomy was noted in 270 out of 355 cases (chi2=0.004, DF=1, p=0.926; Yates=0.00, p=1.00). There was no significant difference of local recurrence and five-year survival between patients treated by classical and extended supraglottic laryngectomy.

[Long-term results of total versus partial laryngectomy for the treatment of squamous-cell carcinoma of the larynx].

OBJECTIVE: To analyze the long-term effects of total versus partial laryngectomy for the treatment of squamous-cell carcinoma of the larynx. METHOD: Of 423 patients with laryngeal carcinoma surgically treated, 327 had supraglottic cancer and 96 had glottic cancer. Total laryngectomy was performed in 243 patients (210 supraglottic and 33 glottic cancers) and partial laryngectomy in 180 patients (117 supraglottic and 63 glottic cancers). RESULTS: The overall 5-year survival rate of patients with supraglottic carcinoma was 72.9%. That of patients treated by total and partial laryngectomy was 70.1% and 77.4%, respectively (P > 0.05). The overall 5-year survival rate of patients with glottic carcinoma was 86.0%. That of patients treated with total and partial laryngectomy was 72.2% and 92.3%, respectively (P < 0.05). CONCLUSION: The long-term result of partial laryngectomy for glottic carcinoma is as good as total laryngectomy, and for supraglottic carcinoma, partial laryngectomy is superior to total laryngectomy. Partial laryngectomy is recommended to treat patients with squamous-cell carcinoma of the larynx. Patients so treated have a better quality of life.

[Clinical evaluation on second stage reconstruction for laryngostenosis after partial laryngectomy for laryngeal cancer patients].

OBJECTIVE: To present a new method of decannulation for laryngostenosis patients after partial laryngectomy and extended partial laryngectomy, and restoration of the essential functions of larynx and normal neck appearance. METHODS: Nineteen cases of laryngostenosis after partial laryngectomy and extended partial laryngectomy were treated with second stage reconstruction. The patients had been treated by vertical laryngectomy (6/19) using extended vertical laryngectomy (11/19) and frontolateral laryngectomy (2/19). Among these patients, second stage reconstruction of larynx was performed by using rotary door myocutaneous flap (17/19). Stemohyoideus flap (1/19) and sternocleidomastoid flap (1/19). RESULTS: Three and five year-survival rates were 91.7% (11/12) and 3/5, respectively. Over-all decannulation rate was 84.2% (16/19), but 94.1% (16/17) in patients with rotary door myocutaneous flap and 0% (0/2) in both patients with sternohyoideus flap and sternocleidomastoid flap. There were 3 decannulation failures (15.8%). All patients resumed acceptable voice, 94.7% (18/19) enjoyed satisfactory phonation, but 5.3% (1/19) showed severe hoarseness. All except 2 patients returned normal swallow function. The latter 2 patients experienced mild abnormal swallow during eating fluid food in early stage of surgery, but had normal swallow function after 1-2 weeks. CONCLUSION: Functional laryngectomy is a radical operation in selected cases with advanced laryngeal cancer. The second stage reconstruction with bi-pedical rotary door myocutaneous flaps can help decannulation in patients who developed laryngostenosis after partial laryngectomy and extended partial laryngectomy, and restore the essential function of larynx and normal neck appearance.
