Management of stage II (T2N0M0) glottic carcinoma by radiotherapy and conservation surgery

BACKGROUND: The best therapeutic approach for the treatment of stage II (T2N0M0) glottic carcinoma is controversial. METHODS: A retrospective tumor registry data retrieval of patients with stage II glottic carcinoma treated with curative intent at Washington University Medical Center-Barnes Hospital between January 1971 and December 1989 (surgery) and December 1995 (radiotherapy) was performed. RESULTS: Among 134 patients with stage II glottic carcinomas treated with curative intent and function preservation, there were 47 patients treated with low dose radiotherapy (median dose, 58.5 Gy at 1.5-1.8 Gy daily fractions), 16 patients with high dose radiotherapy (67.5-70 Gy) at higher daily fractionation doses (2-2.25 Gy), and 71 patients underwent conservation surgery. The overall local control rate was 85%. The overall salvage rate was 68%. The 5-year actuarial and disease specific survivals were 81.5% and 92%, respectively. Unaided phonation was achieved in 84.4% of the patients. An incidence of 10.4% regional metastases, 2.2% distant metastases, and 6% second primary tumors was documented. There were no statistical differences in local control, voice preservation, and 5-year actuarial and disease specific cure rates between conservation surgery and high dose radiation (p = .89). Low dose radiation had statistically lower local controls, 5-year survival, and voice preservation (p = .014). In advanced T2B disease, treating the ipsilateral neck nodes reduced regional metastases (p = .02). CONCLUSIONS: High dose and daily fractionation (70 Gy at 2 Gy daily fraction doses) radiation achieved results equivalent to those of conservation surgery in 5-year local control, survival, and voice preservation. In advanced T2B disease, treatment of the ipsilateral neck nodes by radiotherapy or functional neck dissection reduced regional metastases.     

"FAR" chemoradiotherapy improves laryngeal preservation rates in patients with T2N0 glottic carcinoma

BACKGROUND: The appropriate treatment approach for patients with T2N0 laryngeal cancer remains highly controversial. Because radiotherapy alone is associated with a high risk of local recurrence, we have developed a triple combination treatment approach consisting of 5-fluorouracil (250 mg/day, i.v.), vitamin A (50,000 unit/day, i.m.) and external radiation (2.0 Gy/day), which we have termed "FAR therapy." METHODS: Patients with T2N0 glottic carcinoma were initially treated with 15 days of FAR therapy, which included a cumulative radiation dose of 30Gy (i.e., "30 Gy of FAR therapy"). Those patients who demonstrated a complete response either clinically or pathologically continued to receive further FAR therapy, with up to 60-70 Gy. All other patients received laryngectomy without any additional treatment. RESULTS: Ninety-five patients were treated according to this program, and most of the patients (98%) were able to complete this treatment course. Eighty-eight patients (93%) were treated with FAR therapy alone. The local control and ultimate local control rates were 91% (85 of 93), and 99% (92 of 93), respectively. The cumulative 5-year voice preservation and complete laryngeal preservation rates were 91% and 87%, respectively. The cumulative 5-year disease-specific survival rate was 97%. CONCLUSIONS: Because a high rate of laryngeal preservation was achieved without compromising disease-specific survival, our treatment approach based on FAR therapy may be promising for the treatment of patients with T2N0 glottic carcinoma.     

Treatment of early stage squamous-cell carcinoma of the glottic larynx: endoscopic surgery or cricohyoidoepiglottopexy versus radiotherapy

BACKGROUND: Both surgery and radiotherapy are recognized treatments of T1-T2 squamous cell carcinoma of the larynx. We retrospectively analyze and compare the oncological outcome of patients treated in a single institution, either by endoscopic surgery or partial supracricoid laryngectomy versus radiation therapy. METHODS: The medical records of 156 patients treated between 1983 and 1996 with either surgery (n = 75) or radiotherapy (n = 81) were reviewed. Male to female ratio, median age, and T-stage distribution were comparable. RESULTS: With a median follow-up time of 59 months, the 5-year cause-specific survival rate of 93% was identical for both groups. The actuarial incidence of metachronous second primaries was 7% at 5 years. Local control at 5 years remained 84% after surgery and 77% after radiotherapy. Anterior commissure infiltration was shown to represent a negative predictive factor of local control for radiotherapy (p =.01). Salvage treatment brought ultimate local control to 96% of patients after surgery and 94% after radiation therapy with long-term laryngeal preservation rate altered significantly (p =.05) in the group of patients who received radiotherapy (90.1% vs 97.4%). CONCLUSION: The treatment of laryngeal cancer is always a compromise between oncological efficiency and preservation of function. Our data suggest that, assuming proper selection of patients, radiation therapy and surgery yield similar local control and survival rates. The functional disadvantages after surgery are moderate and clearly counterbalanced by a significant decrease in long-term laryngeal preservation rate after radiotherapeutic treatment.     

CO(2) laser surgery in the treatment of glottic cancer

BACKGROUND: The aim of the study was to assess the effectiveness of CO(2) laser endoscopic surgery in the treatment of glottic carcinoma limited to the true vocal cords or involving the adjacent regions. METHODS: Seven hundred nineteen patients (687 men and 32 women; mean age, 60.4 years; range, 33-86 years) with glottic carcinoma (432 T1N0M0, 236 T2N0M0, 51 T3N0M0) underwent CO(2) laser surgery (mean follow-up, 5 years; range, 2-17 years). Statistical comparison was carried out with Wilcoxon test, considering p < .05 the minimum significance value. RESULTS: Overall actuarial survival, adjusted actuarial survival, and percentage of patients with no evidence of disease at 5 years were 85%, 97%, and 85%, respectively, in patients with T1a disease; 84%, 96%, and 83% in those with T1b disease; 77%, 86%, and 61% in those with T2 unilateral tumors; 77%, 88%, and 55% in those with T2 bilateral tumors; and 64%, 72%, and 60% in those with T3 disease. The statistical analysis showed the following: significant differences in the comparison of T1 versus T2 and T2 versus T3 tumors (p < .01), with the exception of no evidence of disease in the comparison of T2 versus T3 (p > .05); and no significant differences in the comparison of unilateral and bilateral tumors (p > .05). Actuarial local control, actuarial nodal control, and actuarial distant metastasis control at 5 years were 85%, 98%, and 99%, respectively, in patients with T1 disease; and 66%, 82%, and 91% in patients with T2 disease; and 66%, 83%, and 95% in patients with T3 disease. The laryngeal preservation rate was 97.3% in the T1 group, 82.5% in the T2 group, and 80.5% in T3 group. CONCLUSIONS: CO(2) laser endoscopic surgery is effective in the treatment of glottic carcinoma not infiltrating the cartilaginous skeleton; the results achieved are competitive with those of open conservative operations, if we take into account the possibilities afforded by salvage surgery and the rate of laryngeal preservation achieved in the study patients.     

Squamous cell carcinoma of the larynx

A patient with a moderately advanced squamous cell carcinoma of the larynx (T2, glottic) is presented. The consultants discuss their preferred diagnostic and treatment options. All consultants agree that the chances for cure (5-yr survival) are 80-85%, but they differ as to the preferred treatment approach to preserve phonation. Drs. Biller and Pearson predict that 80-90% of patients would be alive and have usable voice, with surgical treatment, whereas Dr. Bryce believes the chances of voice preservation are 65% after radiotherapy only. In his opinion an additional 10% would be helped by conservation partial laryngeal surgery.     

Platysma skin flap: Laryngeal repair material to produce phonatory flap vibrational wave

The platysma skin flap was used for laryngeal reconstruction after vertical partial laryngectomy to improve the postoperative voice quality of patients with T2 and T3 glottic laryngeal carcinoma. Sixty‐nine patients with unilateral T2 and T3 glottic laryngeal carcinoma were included. Forty‐six patients received vertical partial laryngectomy, and a platysma skin flap was used for laryngeal reconstruction. The other 23 patients underwent transoral laser microsurgery. Subjective and objective examinations were performed to evaluate laryngeal morphology after the surgery. Acceptable voice quality was achieved for 46 patients who underwent vertical partial laryngectomy. Flap vibrational waves occurred in 19 cases (41.3%). The platysma skin flap is an ideal tissue for the reconstruction of articulation structure in open surgery of T2 and T3 unilateral glottic laryngeal carcinoma.     

Management and outcome of early glottic carcinoma.

OBJECTIVE AND STUDY DESIGN: We designed a retrospective study to analyze treatment methods and outcomes for patients with lesions ranging from carcinoma in situ to invasive T1 glottic squamous cell carcinoma. Patients with nonsquamous cell carcinoma, verrucous variant of squamous cell carcinoma, anterior commissure involvement, and T2 lesions were excluded. SETTING: University of Pittsburgh School of Medicine, a tertiary referral center. RESULTS: Fifty-four patients met the inclusion criteria. Mean follow-up was 49 months (range 24 to 96 months). Forty-eight of 54 (89%) were treated with endoscopic excision. Forty of these 48 patients (83%) were successfully treated with endoscopic excision(s) as the only treatment modality. Four patients had persistence of disease despite multiple endoscopic excisions. Two of these patients underwent hemilaryngectomy, 1 received radiation treatment, and 1 received radiation therapy followed by a hemilaryngectomy. Four patients had recurrence of disease. Two patients with recurrence required radiation therapy and 2 patients required a total laryngectomy. With the selective application of multiple endoscopic excisions, radiation therapy, and more invasive operation, 100% of patients are without evidence of disease with a laryngeal preservation rate of 96%. CONCLUSIONS: This study supports the use of endoscopic excisional biopsy as the primary treatment modality for lesions ranging from carcinoma in situ to invasive T1 glottic carcinoma. This study also highlights the importance of close clinical follow-up and the potential need for further treatment. By reserving open operation and radiation therapy to selective cases, we successfully treated all patients while limiting the disadvantages of radiation therapy and more invasive operation to the minority of patients.     

Conservation laryngeal surgery versus total laryngectomy for radiation failure in laryngeal cancer

BACKGROUND: Total laryngectomy is the standard of care for surgical salvage of radiation failure in laryngeal cancer. However, the role of conservation laryngeal surgery in this setting remains unclear. The objective was to compare the efficacy of conservation versus total laryngectomy for salvage of radiation failure in patients who initially presented with T1 or T2 squamous cancer of the larynx. METHODS: A 21-year retrospective analysis of patients who received surgery at a single comprehensive cancer center after definitive radiation therapy is reported. At recurrence, the patients were reevaluated and then underwent a total laryngectomy or, if possible, a conservation laryngeal procedure. The charts of 105 patients who failed radiation treatment for primary laryngeal cancer and who subsequently underwent surgical salvage were reviewed for this study. Eighty-nine were male (84.8%). The mean age was 60.3 years. The median follow-up time after surgery was 69.4 months. Most patients with recurrence after radiotherapy required total laryngectomy (69.5%; 73/105). Conservation laryngeal surgery was performed for 32 patients (31.5%). Concomitant neck dissections were performed on 45 patients (45.5%). RESULTS: In 14 patients, local or regional recurrence developed after salvage surgery: 9 patients after total laryngectomy (12.3%; 9/73), and 5 patients (15.6%; 5/32) after conservation laryngeal surgery. This difference was not statistically significant, nor was there a difference in disease-free interval for the two procedures (p = .634, by log-rank test). Distant metastasis developed in 13 patients. Most developed in the setting of local and/or regional recurrence, but distant metastasis occurred as the only site of failure in 6 of the patients who had undergone total laryngectomy but in 1 of the conservation surgery patients treated for a supraglottic laryngeal cancer. The overall mortality for patients who underwent total laryngectomy was also higher: 73.74% (54/73) versus 59.4% (19/32) for patients who underwent a conservation approach (p = .011 by log-rank test). CONCLUSIONS: Although conservation laryngeal surgery was possible in a few patients with local failure after radiotherapy, conservation laryngeal surgery is an oncologically sound alternative to total laryngectomy for these patients.     

Carbon dioxide laser microsurgery for early glottic carcinoma

OBJECTIVES: To define the oncologic efficacy of transoral endoscopic CO2 laser surgery in early glottic carcinoma. METHODS: A retrospective study of 103 patients with glottic carcinoma (14 Tis, 68 pT1a, 14 pT1b, and 7 pT2) treated from October 1993 to June 2001. Surgical treatment included endoscopic CO2 laser cordectomies according to the classification of the European Laryngological Society. RESULTS: According to the Kaplan-Meier method, the probability of remaining free of local recurrence 5 years after primary surgery alone was 100% for the Tis, 96.05% for the T1, and 100% for the T2. Local control at 5 years after exclusive CO2 laser salvage surgery was 98.03%. The probability of remaining free of local recurrence 5 years after any type of salvage surgery was 100%. Laryngeal preservation was achieved in 100% of the cases. CONCLUSIONS: According to the present series, endoscopic CO2 laser surgery is an effective treatment for early glottic cancer. EBM RATING: C-4.     

Results of hemilaryngectomy in primary surgical treatment of laryngeal carcinoma

Hemilaryngectomy is the resection of a true anatomic half of the larynx with preservation of the cricoid cartilage. We present a retrospective study of 438 patients with glottic carcinoma, treated with hemilaryngectomy, at the Institute of Otorhinolaryngology and Maxillofacial Surgery, Clinical Center of Serbia between 1988 and 1997. The patients with positive margins (19.4% of all) were postoperatively irradiated. Local recurrences of carcinoma were found in 17.3% of subjects, and regional recurrences in 16.4% of subjects. Those patients were treated with total laryngectomy or radical neck dissection, and with radiotherapy. 5-years survival rate in our patients was 79%. Hemilaryngectomy provided acceptable percent of local and regional recurrences, and good functional results: respiration, swallowing and voice quality. Therefore it could be the first choice surgery technique in treatment of T2 laryngeal carcinoma.     

High-dose preoperative radiation and radical sphincter-preserving surgery for rectal cancer.

To reduce local recurrence associated with rectal cancer and to extend the scope of anal sphincter preservation, a selective program of high-dose preoperative radiation therapy and sphincter-preserving surgery was initiated in 1976. High-energy photon therapy (40 to 60 Gy) was administered in doses of 1.8 to 2.5 Gy during a period of 4 1/2 to 6 weeks and followed in 4 to 6 weeks with curative sphincter-preserving surgery for clinicopathologically unfavorable and low rectal cancers. None of the 143 patients in the study died during the postoperative period. Fifteen (13%) of 117 patients followed up for at least 24 months experienced local recurrence. Acceptable sphincter function was retained in 130 patients (91%). Our program of high-dose preoperative radiation therapy and sphincter-preserving surgery for the treatment of high-risk cancers, including those in the distal third of the rectum, resulted in better-than-expected survival and control of local recurrence with acceptable morbidity and no mortality.     

Laser cordectomy for T1 glottic carcinoma: a 10-year experience and videostroboscopic findings

Fifty-three patients underwent laser cordectomy for T1 glottic squamous cell carcinoma between January 1980 and December 1989--sixteen after having undergone unsuccessful radiation and thirty-seven who had no previous treatment. There was a 51% five-year cure rate in the irradiated group vs. 62% in the nonirradiated group. Extension of tumor to the anterior commissure resulted in a higher failure rate. Patients experienced an overall 5-year cure rate of 98% after surgical or radiation salvage of unsuccessful laser cordectomies. Six patients had preoperative and postoperative videostrobolaryngoscopy. The most common postoperative problem with voice was a breathiness that did not resolve in any of the patients. All patients had absent or moderately reduced amplitude and mucosal wave patterns and imcomplete glottic closure proportional to the amount of cordal tissue removed. Despite it seemingly poor results in carefully selected patients, laser cordectomy is still indicated without compromising the ultimate oncologic results. Advantages over radiation therapy or conservation laryngeal surgery include a short treatment time, requiring only an outpatient surgical procedure at the time of the initial diagnostic and/or staging laryngoscopy, and the avoidance of potential radiation side effects or surgical complications. However, patients should be advised the possibility of persistent postoperative breathy dysphonia, in addition to the possibility of further treatment to effect a long-term cure.     

Endoscopic laser surgery in the treatment of radiation failure of early laryngeal carcinoma

BACKGROUND: This study was undertaken to analyze the local control rates and survival of patients undergoing endoscopic laser surgery for squamous cell carcinoma of the larynx as a salvage procedure for recurrent tumors after radiotherapy. METHODS: Twenty-four patients underwent endoscopic laser surgery for radiation failure at our hospital from 1988 to 1995. All patients were men, between 45 and 88 years old. The localization of the recurrence was in the supraglottis in 3 cases and in the glottis in 21 cases. The postirradiation recurrences were staged rT1 in 18 patients and rT2 in 6 patients. RESULTS: Local recurrence after laser surgery developed in six patients (25%) who had a total laryngectomy. Voice preservation was thus achieved in 75% of patients. No patient died because of the laryngeal cancer, and the observed 5-year survival rate was 76%. CONCLUSIONS: These results indicate that in selected cases, endoscopic laser surgery may be used successfully for treating radiation failure of early laryngeal carcinomas.     

Fractures following radiotherapy and limb-salvage surgery for lower extremity soft-tissue sarcomas. A comparison of high-dose and low-dose radiotherapy

BACKGROUND: The purpose of the present retrospective study was to determine the correlation between radiation therapy and the risk of postradiation fracture following combined therapy for the treatment of soft-tissue sarcomas of the lower extremity. METHODS: Three hundred and sixty-four patients with lower extremity sarcomas that had been treated with combined external beam radiation therapy and limb-salvage surgery were evaluated on the basis of a combined chart and data-base review. For the purposes of analysis, high-dose radiation was defined as 60 or 66 Gy and low-dose radiation was defined as 50 Gy. The timing of irradiation was defined as preoperative, postoperative, or preoperative followed by a postoperative boost. Univariate and multivariate analyses were used to determine which factors were associated with fracture risk. RESULTS: Twenty-seven fractures occurred in twenty-three patients. Twenty-four fractures occurred in twenty patients who had been managed with high-dose radiation. Seventeen of these patients had received postoperative radiation (with fifteen patients receiving 66 Gy and two receiving 60 Gy), and three had received preoperative radiation with a postoperative boost (total dose, 66 Gy). Three fractures occurred in three patients who had received preoperative, low-dose radiation (50 Gy). Of the twenty-three patients who sustained a pathologic fracture, eighteen were female and five were male. The crude median time to fracture was forty-three months. Most fractures occurred in the femoral shaft (thirteen) or the femoral neck (eight). High-dose radiation was associated with a greater risk of fracture when compared with low-dose radiation (p = 0.007). CONCLUSIONS: Women more than fifty-five years of age who are managed with removal of a thigh sarcoma combined with radiation therapy have a higher risk of pathologic fracture. The frequency of pathologic fractures associated with higher doses (60 or 66 Gy) of radiation is significantly higher than that associated with lower doses (50 Gy).     

Salvage with supracricoid partial laryngectomy after radiation failure

BACKGROUND: Supracricoid partial laryngectomy (SCPL) is an alternative to total laryngectomy (TL) for selected glottic and supraglottic carcinomas but its role in the setting of radiation failure is unclear. The aim of the present study was to present a series of patients with laryngeal cancer undergoing salvage surgery for local recurrence and examine the morbidity associated with this intervention. METHODS: A retrospective review of 111 patients presenting with laryngeal cancer between 1997 and 2002 was performed. A total of 21 patients with recurrent disease following radiation therapy were identified, of which salvage surgery was performed in 18 patients. Minimum follow up of survivors was 22 months. RESULTS: The 5-year cumulative local control and disease-specific survival was 76% and 85%, respectively. Surgical salvage consisted of TL in 12 patients and SCPL in six. The mortality and major morbidity rates for TL were 0% and 33%, and for SCPL they were 33% and 50%, respectively. Median length of hospital stay was similar in both groups (21 and 19 days). No patient undergoing SCPL developed recurrent disease at a median follow up of 19 months. CONCLUSIONS: Supracricoid partial laryngectomy is an oncologically sound alternative to TL as salvage for radiation failure. The operative morbidity and potential for mortality is high in this setting.     

Carbon dioxide laser salvage surgery after radiotherapy failure in T1 and T2 glottic carcinoma.

OBJECTIVES: Recurrent glottic carcinoma after radiotherapy (RT) may be managed by open neck or endoscopic surgery. The impact of endoscopic treatment with CO(2) laser for recurrent glottic carcinoma after RT is reported. METHODS: We present the oncologic and vocal outcomes of a retrospective study based on a series of 16 patients with rT1 and rT2 glottic carcinoma who were endoscopically managed between February 1995 and December 1999 after RT failure. All patients were males with a mean age of 68.7 years (range, 50 to 87 years). Before RT, the lesions had been staged as T1 N0 in 11 patients and T2 N0 in 5, and after RT as rT1 N0 in 12 and rT2 N0 in 4. According to the European Laryngological Society classification, a total of 9 transmuscular, 3 total, and 4 extended cordectomies were performed. Mean follow-up was 45 months (range, 9 to 79 months). RESULTS: Endoscopic salvage surgery was successful in 14 patients. One of them developed a second recurrence and was definitively cured with an additional endoscopic procedure. Two of the 16 patients had recurrent disease after salvage laser surgery and died due to progression of disease. Ultimate local control with laser alone at 3 years was 87.1%, according to the Kaplan-Meier method. Laryngeal preservation was obtained in all survivors after endoscopic rescue surgery. Voice analysis showed a clear correlation between the amount of vocal cord tissue resected and decrease of the vocal outcome. CONCLUSIONS: The present series indicates that selected recurrences after primary RT for T1 and T2 glottic carcinoma are eligible for endoscopic salvage surgery with oncologic results comparable to those with open neck procedures but with a lower complication rate and a favorable functional outcome.     

Objective and self-evaluation voice analysis after transoral laser cordectomy and radiotherapy in T1a-T1b glottic cancer

Voice quality outcome becomes an important factor in the choice of the therapeutic option. The differences between radiotherapy and laser cordectomy have been extensively debated in the literature. We analyzed the vocal outcomes after carbon dioxide (CO₂) laser cordectomy and radiotherapy treatment for T1a-b early glottic cancer by means of objective and subjective voice evaluation. A retrospective study was performed on 56 cancer patients, 30 treated with cordectomy and 26 with radiotherapy. All patients underwent laser cordectomy which was performed under general anesthesia using a surgical microscope in laryngeal suspension. The laser we used was an Ultrapulse one, 10.6-μm wavelength, and a power setting of 2 to 4 W in an Ultrapulse mode was selected. Two different sets of data were recorded: (a) voice acoustic analysis (jitter, shimmer, fundamental frequency and noise/harmonic ratio) and (b) voice handicap index (VHI). Data collected were statistically analyzed using SPSS 20.0 for Windows. Jitter, shimmer, and signal-to-noise ratio were significantly altered in both glottic cancer patient groups as compared to the control group. On the contrary, no statistically significant alteration of the fundamental frequency was found in both treatment groups. Interestingly, jitter and shimmer values were significantly more compromised in transoral laser surgery patients as compared with radiotherapy-treated patients. The VHI was also significantly altered in both cancer patient groups as compared to the control group. More importantly, however, the self-evaluation voice analysis was not significantly different between the two treatment groups, contrary to what we observed for two of the four parameters measured in the objective voice analysis. Given the importance of the self-perception of the voice quality, no treatment can be considered superior from the patients’ point of view. Therefore, we suggest that priority should be given to the endoscopic surgery, due to lower costs, lower morbidity, and shorter hospitalization.     

Primary radiation therapy for early glottic cancer.

OBJECTIVES/HYPOTHESIS: Early glottic squamous cell carcinoma can be effectively treated with either radiation or surgical intervention. We evaluated our experience treating early glottic cancer with primary radiation therapy and our vertical hemilaryngectomy (VHL) salvage experience. STUDY DESIGN/METHODS: Retrospectively, patient records between January 1986 and December 1994 were reviewed and 45 patients with early glottic squamous cell carcinoma who received full-course radiation therapy at the Cleveland Clinic Foundation were identified. RESULTS: Local control after radiation therapy was 80% overall, 87.5% for T1 lesions, and 75% for T2 lesions. Four patients underwent VHL for salvage after local recurrence; 1 was successfully salvaged with VHL. Five patients underwent total laryngectomy salvage after radiation therapy; all were successful. Only 1 of the 6 patients who were originally candidates for VHL before radiation therapy was successfully salvaged with the larynx preserved. CONCLUSIONS: Our local control rates using primary radiation therapy are consistent with prior published series, but voice sparing salvage is poor.     

Laryngeal reconstruction by platysma myofascial flap after vertical partial laryngectomy

BACKGROUND: Many methods of glottic reconstruction have been described for patients undergoing vertical partial laryngectomy to reestablish the glottic integrity. METHODS: Fifteen patients with T2 squamous cell carcinoma of the glottis were included in this prospective clinical trial. All patients were treated by vertical partial laryngectomy with laryngeal reconstruction by platysma myofascial flap. The surgical procedure and flap design were described. Vocal function was assessed by videolaryngostroboscopy and subjective and objective voice analysis before and after surgery. RESULTS: Complete neoglottic closure and acceptable voice quality were obtained by platysma myofascial flap in all cases. No statistically significant difference was found between the preoperative and postoperative acoustic parameters. CONCLUSIONS: Platysma myofascial flap provides the basic requirements for laryngeal reconstruction with its own favorable characteristics and also allows complete glottic closure without interfering with respiration and deglutition. This technique may be an effective alternative achieving an acceptable quality of voice.
