Vertical Partial Laryngectomy With Temporoparietal Free Flap Reconstruction for Recurrent Laryngeal Squamous Cell Carcinoma

To present a technique for reconstruction of the vertical partial laryngectomy defect using a vascularized carrier consisting of a temporoparietal free flap, cartilage graft, and buccal mucosal graft; to evaluate the oncologic outcomes with respect to locoregional control and overall survival; and to provide an assessment of patient quality of life and functional outcomes. Retrospective medical record review and prospective cross-sectional analysis of functional outcomes. Princess Margaret Hospital-University Health Network and the Odette Cancer Centre-Sunnybrook Health Sciences Centre. We collected data on patient demographic characteristics, tumor staging, initial treatment, recurrence, management, and follow-up. Prospectively, a cross-sectional study was performed using the European Organization for Research and Treatment of Cancer Quality of Life of Cancer Patients Questionnaire C30 and HN35 module and voice and swallowing results using the Voice Handicap Index and Swallowing Quality of Life index. Local recurrence-free survival, cause-specific survival, and overall survival. Forty men met inclusion criteria (median age, 65.0 years). Local recurrence-free survival was 84% at 3 years and 75% at 5 years. Cause-specific survival was 88% at 3 years and 78% at 5 years. Thirty-eight patients were successfully decannulated; all patients tolerated oral intake after the surgical procedure. The C30 and HN35 symptomatic results were comparable with patients with standardized stages I and II head and neck tumors. The Voice Handicap Index results were comparable with patients with functional dysphonia. Patients' swallowing was in the normal range. Patients receiving vertical partial laryngectomy with temporoparietal free flap reconstruction for recurrent glottic carcinoma following radiation treatment failure have high rates of locoregional control. The use of the temporoparietal free flap in this patient population produces high-quality voice results and normal swallowing and has no major effect on quality of life.

CT-scan prediction of thyroid cartilage invasion for early laryngeal squamous cell carcinoma

Treatment choice for laryngeal cancer may be influenced by the diagnosis of thyroid cartilage invasion on preoperative computed tomography (CT). Our objective was to determine the predictive value of CT for thyroid cartilage invasion in early- to mid-stage laryngeal cancer. Retrospective study (1992-2008) of laryngeal squamous cell carcinoma treated with open partial laryngectomy and resection of at least part of the thyroid cartilage. Previous laser surgery, radiation therapy, chemotherapy and second primaries were excluded. CT prediction of thyroid cartilage invasion was determined by specialized radiologists. Tumor characteristics and pathologic thyroid cartilage invasion were compared to the radiologic assessment. 236 patients were treated by vertical (20 %), supracricoid (67 %) or supraglottic partial laryngectomy (13 %) for tumors staged cT1 (26 %), cT2 (55 %), and cT3 (19 %). The thyroid cartilage was invaded on pathology in 19 cases (8 %). CT's sensitivity was 10.5 %, specificity 94 %, positive predictive value 13 %, and negative predictive value 92 %. CT correctly predicted thyroid cartilage invasion in only two cases for an overall accuracy of 87 %. Among the false-positive CT's, tumors involving the anterior commissure were significantly over-represented (61.5 % vs. 27 %, p = .004). Tumors with decreased vocal fold (VF) mobility were significantly over-represented in the group of false-negatives (41 vs. 13 %, p = .0035). Preoperative CT was not effective in predicting thyroid cartilage invasion in these early- to mid-stage lesions, overestimating cartilage invasion for AC lesions and underestimating invasion for lesions with decreased VF mobility.

The aim of the study was to evaluate the results of partial laryngectomies in patients with laryngeal cancer treated in the 2(nd) Clinical Department of Laryngology SUM in Zabrze in the years 1990-2000. Retrospective clinical material includes 209 patients in whom surgery was a primary treatment method. No distant metastases (M1) or another malignant cancer were found. The group consisted of 20 (10%) women and 189 (90%) men. The mean age was - 51.2 years. The stage of the neoplasm progression was defined as T1 in 91 patients (44%), T2 in 109 patients (52%). In other 9 patients (4%) the progression stage was T3 and T4. Clinical examination in 191 patients (91%) did not show enlarged lymph nodes in the area of head and neck (N0). In the group of remaining 18 patients (9%) the node progression was found to be N1-N3. In all 209 patients the squamous cell carcinoma of various stage of malignancy (G1-G3) was found in preoperative histopathological tests, out of which five cases were of papillary squamous cell carcinoma. The most common operation in the analyzed group was a chordectomy - 83 surgeries (40%), followed by 38 (18%) vertical partial laryngectomies, 28 (13%) horizontal glottis surgeries, 19 (9%) frontal-lateral and frontal-anterior operations, and supracricoid operations with a reconstruction of CHEP and CHP type, a total of 20 operations (9%). Other types of partial operations were performed less commonly. In 79 patients (38%) partial laryngectomy was complemented with a nodal operation, while cervical lymph nodes were not removed in 130 patients (62%). In 19 cases (9%) the metastases of squamous cell carcinoma to regional lymph nodes were confirmed in postoperative material. 82 patients of the study group (39%) underwent radiotherapy. The median of the observation period was 9 years. Local recurrence, nodal recurrence and distant metastasis are rated as treatment failure. Treatment effectiveness was evaluated with relation to local control, overall survival, disease-free survival and cause specific survival. All the aforementioned parameters were analyzed with the method of updated percentages. The level of statistical significance was assumed to be p ≤ 0.05. The updated 5-year and 10-year percentage of overall survivals was respectively 75% and 63%. The updated 5-year and 10-year percentage of cancer specific survivals was 85% and 79%, respectively. The updated 5-year and 10-year percentage of disease-free survivals was 72% and 56%, respectively. The percentage of 5-year and 10 year local controls was 86% and 79%, respectively.

Vertical Partial Laryngectomy for Salvage after Failure of Irradiation

The Current Role of Partial Surgery As a Strategy for Functional Preservation in Laryngeal Carcinoma

With the current advances and recent organ preservation protocols for intermediate or advanced stage laryngeal cancer, based on chemotherapy, the role of surgery seemed replaced except for surgical rescue of tumours not responding to these treatments, total laryngectomy being the surgical option. This type of non-surgical treatment is offered as a strategy for organ preservation, as opposed to total laryngectomy. However, we believe that there are two organ-preservation strategies, surgical and non-surgical. A wide spectrum of surgical techniques is available and such techniques lead to excellent results, both oncological and functional (speech and swallowing). The aim of this paper is to present options for organ-preserving surgery for laryngeal cancer. A review of surgical techniques available for functional preservation in cancer of the larynx at intermediate or advanced stage is presented. In addition to the classic approaches, such as vertical partial laryngectomy and horizontal or supraglottic laryngectomy, options for conservative laryngeal surgery have improved significantly over the past two decades. Minimally invasive surgery, transoral laser surgery, and supracricoid partial laryngectomy have become important laryngeal preservation approaches for patients with laryngeal cancer. Surgery must define its role in the multidisciplinary treatment of advanced cancers of the larynx, which at present often favours (chemo)radiotherapy protocols.

Primary Vertical Partial Laryngectomy for T1‐T3 Squamous Cell Carcinoma of the Glottic Larynx

Objective: Squamous cell carcinoma of the glottis represents one of the most common malignancies of the head and neck. Although non-operative treatment of these lesions has dominated the last two decades, the use of surgical options, particularly transoral laser microsurgery, has recently seen an increase. Considering this paradigm shift, we seek to revisit the therapeutic role of vertical partial laryngectomy and present our experience with its application for T1-T3 glottic carcinoma.

Laryngeal framework reconstruction using titanium mesh in glottic cancer after frontolateral vertical partial laryngectomy

To investigate the feasibility and efficacy of laryngeal framework reconstruction using titanium mesh in patients with glottic cancer after frontolateral vertical partial laryngectomy. Prospective study. Defect of laryngeal framework, caused by frontolateral vertical partial laryngectomy in nine patients with T2 or T3 squamous cell carcinoma of glottic, were reconstructed with titanium mesh from 2007 to 2009. Computed tomography (CT) and fiberscopic examinations were performed at two weeks and three months postoperatively. No aspiration and laryngeal stenosis was observed in the nine patients. CT scanning showed that titanium mesh was fastened well without displacement and deformity and that there was no laryngeal stenosis. Fiberscopic inspection showed that the larynx lumen was maintained well without stricture, shrinkage, and necrosis. No titanium mesh was exposed to the larynx lumen. Titanium mesh was a good alternative for reconstruction of the laryngeal framework. It provided adequate structural support to maintain airway patency.

Conservation Surgery for Early Laryngeal Carcinoma

Background: Squamous cell carcinoma is the commonest malignant tumour of the larynx. The traditional treatment options have included radiotherapy and total laryngectomy. Due to the pivotal role of the larynx in respiration, speech and deglutition, conservative approaches to the management of malignant lesions were suggested. These organ-preserving policies aim at preserving most of the laryngeal functions without compromising the oncological outcomes. Such approaches include organ-preserving radio/chemotherapy protocols, endoscopic laser surgery, photodynamic therapy and open conservative surgery. Each of these has their indications, advantages and disadvantages. The modern trend towards organ preservation protocols and endoscopic laser techniques seems to have supplanted open conservative surgery. However, these techniques still have an important role in the management of laryngeal malignancies. Methods: This is retrospective study on 216 patients followed for a minimum of 2 years and a maximum of 16. All patients underwent partial surgery as first-line treatment: 135 underwent partial vertical laryngectomy, 76 underwent supraglottic hemilaryngectomy and 5 underwent supracricoid subtotal laryngectomy. Results: Our overall disease-free survival was 92.1%, which compares favourably with most series. Total laryngectomy was performed in 11 patients (in 10 as salvage and in 1 for intractable aspiration) resulting in a laryngeal preservation rate of 94.4%. The decanulation rate was 95% (11 patients in the three types of surgery). There were no major morbidities or surgery-related mortalities. The most significant complication was aspiration (18.9% of patients), but it could be managed conservatively in all but one case. Conclusion: In this era of organ preservation policies, open conservative surgery offers a viable option with comparable functional and oncological results. It should be considered when logistic, economical or patient factors make other protocols impractical.

Organ preservation surgery for laryngeal squamous cell carcinoma: Low incidence of thyroid cartilage invasion

Determine the incidence and risk factors for thyroid cartilage invasion in early and midstage laryngeal cancer. Retrospective review. A retrospective review was carried out of tumors treated by open surgery with at least partial resection of thyroid cartilage from 1992 to 2008. Preoperative laser, radiation therapy, or chemotherapy were excluded. Tumor stage, anterior commissure involvement, vocal fold (VF) mobility, computed tomography (CT) scan, and pathological cartilage status were recorded. Three hundred fifty-eight patients were treated for tumors staged cT1 (32%), cT2 (53%), and cT3 (15%) by vertical (26%), supracricoid (62%), or supraglottic partial laryngectomy (12%). The thyroid cartilage was invaded in 8.9% of cases. Abnormal VF mobility was significantly related to thyroid cartilage invasion (Fisher exact test, P = .0002). Neither anterior commissure involvement nor CT scan were related to cartilage invasion. Thyroid cartilage invasion was rare but increased if VF mobility was impaired. This has implications for transoral resection, which unlike open surgery avoids unnecessary cartilage resection.

Comparing extended vertical partial laryngectomy and cricohyoidoepiglottopexy in the treatment of laryngeal carcinoma

To compare the results of extended vertical partial laryngectomy (similar to modified supracricoid partial laryngectomy with cricohyoidoepiglottopexy) and cricohyoidoepiglottopexy in the treatment of laryngeal carcinoma. Retrospectively analyzed on the results and prognosis in patients underwent extended vertical partial laryngectomy and cricohyoidoepiglottopexy between 1998 and 2005. The operation was similar to extended vertical partial laryngectomy. The healthy vocal cord and ventricular band as well as about 1/3 to 2/3 laminas of thyroid cartilage were removed. The healthy cricoarytenoid joint was reserved. The vocal cord, ventricular band, fixed or limitation of motion arytenoid cartilage and 2/3 laminas of thyroid cartilage in ill side were removed. The posteroinferior border of laminas of thyroid cartilage in both sides were reserved. The cricoid was lifted and fixed with hyoid epiglottis directly. Extended vertical partial laryngectomy group consisted of 37 patients with glottic carcinoma (stage T2 16 cases, stage T3 21 cases) and cricohyoidoepiglottopexy group consisted of 34 patients with glottic carcinoma (stage T2 12 cases, stage T3 21 cases, stage T4 1 case). Kaplan-Meier analysis was performed to calculate the survival rates. The three-year cumulative survival rate was 91.7% in extended vertical partial laryngectomy group and 87.5% in cricohyoidoepiglottopexy group respectively. There was no significant difference between the two groups (P > 0.05). The five-year cumulative survival rate was 80.6% in extended vertical partial laryngectomy group and 81.3% in cricohyoidoepiglottopexy group respectively. There was also no significant difference between the two groups (P > 0.05). The decannulation rate was 100% (37/37) in extended vertical partial laryngectomy group and 94.1% (32/34) in cricohyoidoepiglottopexy group respectively. The decannulation time was (14.0 + or - 2.3) days in extended vertical partial laryngectomy group and (19.0 + or - 4.6) days in cricohyoidoepiglottopexy group respectively. The incidence of aspiration was 2.7% (1/37) in modified group and 23.5 (8/34) in cricohyoidoepiglottopexy group respectively evaluated at 8th weeks post-operatively. The evaluation of deglutition disorder was analyzed by Ridit analysis in both groups and the results showed that there was significant difference between the two groups (U = 7.341, P < 0.001). The symptom of aspiration in extended vertical partial laryngectomy group was significant less than in cricohyoidoepiglottopexy group. Although the survival rate was not different between the two groups. The preservation of laryngeal function in extended vertical partial laryngectomy group was significant better than in cricohyoidoepiglottopexy group and extended vertical partial laryngectomy.

In the treatment of early-stage larynx cancer, radiotherapy or operations such as partial laryngectomies are performed to preserve laryngeal function. A partial vertical laryngectomy is performed for laryngeal function preservation, and is suitable for cases in which the tumor exists at the unilateral vocal cord and spreads to the commissura anterior, but progress is less advanced in the unaffected vocal cord. Recently, the partial vertical laryngectomy is not performed for initial treatment, and has been increasingly used as salvage surgery when the tumor recurs after irradiation. In this instance, we may recognize postoperative complications by damage to the skin and subcutaneous tissue. We report here on a partial vertical laryngectomy with reconstruction using a thyroid gland flap.

Investigation about remote quality of life of patients with tumor of larynx when abscised by differ-ent type

Objective To know the remote quality of life of patients with tumor of larynx when ab-scised by different type, and then summarize proper countermeasures of nursing. Methods Selected 82 laryngocarcinoma patients with exacte]y diagnosis. There were 40 cases had received total laryngectumy, 42 cases had received partial laryngectomy. Evaluated the level of remote quality of life of 82 patients by QLQ-H&N65, and then analyzed the datum. Results The level of quality of life of patients with total laryn-gectomy were worse than those in patients with partial laryngectomy in the aspects such as general health, swallow, language, emotional function, social function, body fuction and so on. Conclusions The quality of life of patients with tumor of larynx is influenced by several factors, their remote quality of life should be emphasised by nurses. Key words: Tumor of larynx; Total laryngectomy; Horizontal partial laryngectomy; Vertical par-tial laryngectomy; Quality of life

The Relationship Between the Glottic Configuration After Frontolateral Laryngectomy and the Acoustic Voice Analysis

The relative measurement of the anterior commissure synechia (S) is a crucial factor worsening voice quality and the perceptual analysis score has a strong correlation to the synechia's impact. The aim of this study is to correlate the laryngeal configuration regarding the anterior commissure synechia and its relationship with the acoustic vocal parameters. Fifteen male patients underwent frontolateral partial vertical laryngectomy and reconstruction with bipedicle sternohyoid muscle flap for the treatment of T1b/T2 glottic cancer. The patients were free of disease, and the evaluation was performed after a minimum postoperative period of 12 months. Measurements of the anterior commissure synechia and the free border of both the preserved and the reconstructed vocal folds were simultaneously performed with the acoustic analysis of the voice. We calculated the mathematical proportion between the midsagital dimension of the synechia of the anterior commissure and the measurement of the free border of the intermembranous region of each vocal fold-the preserved one and that reconstructed with the bipedicle sternohyoid muscle flap. The acoustic evaluation showed an important increase in the fundamental frequency, and the values of all parameters were changed regardless of the anterior commissure synechia findings. These results suggest that the acoustic voice parameters are always changed because of the aperiodic pattern regardless of the anterior commissure synechia findings.

Comparison among different available surgical approaches in T1 glottic cancer

This study aims to assess the oncologic results of open and transoral surgical techniques in T1a and T1b category glottic carcinomas. Retrospective clinical study. The files of 438 T1a and T1b glottic cancer cases managed with primary surgery were reviewed. Transoral laser surgery and open surgical procedures used to treat these cases, including cordectomy, vertical partial laryngectomy, and frontolateral partial laryngectomy, were compared for disease specific survival and local control rates. In addition, all techniques were compared for incidence of major complications and related tracheotomies. No statistically significant differences were noted between laser surgery and open procedures with regard to disease specific survival and local control for both T1a and T1b cases. Laser surgery showed a significantly lower incidence of complications and tracheotomies. Laser surgery appears to be a very effective management modality for T1 glottic cancer with comparable results to open procedures and a lower incidence of complications. A transcervical approach should be reserved only for selected cases where individual anatomic factors do not permit complete tumor exposure during diagnostic microlaryngoscopy.

Endoscopic Partial Laryngectomy with the CO2 Laser Fiber‐‐Successful Management of Adult Laryngeal Rhabdomyoma

Results: Patient is a 60 year-old male who was referred to our department with worsening hoarseness over the last 20 years. Initial panendoscopy and biopsy demonstrated laryngeal rhabdomyoma that was occupying the right hemilarynx with right arytenoid immobility. The patient underwent successful endoscopic vertical partial laryngectomy with the Omniguide® CO2 laser fiber. The patient did not need a tracheostomy and was tolerating a regular diet on post-operative day 2 and had an adequate voice. Surveillance MRI’s have shown no recurrence of disease.

Myoepithelioma of the larynx: a case report

Myoepithelioma of the larynx is a very rare tumor with nonspecific local symptoms. We present the second known case, focusing on the peculiarities of the differential diagnosis for this type of tumor that are crucial for the right histologic diagnosis and furthermore for the therapeutic outcome.We report a 37-year-old male presenting with hoarseness and dyspnea. The indirect laryngoscopy revealed a gross glottic tumor from the right vocal cord who occupied the greater part of the glottis. No apparent cartilage invasion was shown in the CT. He came to us with a previous direct laryngoscopy derived biopsy describing a chondroma. A modified vertical partial laryngectomy, under temporary tracheostomy, with muscle reconstruction for the deficit of the right vocal cord was applied for the removal of the tumor. The final histopathologic diagnosis was myoepithelioma (spindle cell type) of the larynx. A long term follow-up in our case showed no recurrence and a good functional result.The larynx is a very rare localization for this type of tumour. The benign character of the disease in conjunction with its slow progression could delay its detection and diagnosis, leading to a more destructive surgery. A detailed pathology examination is prerequisite for avoidance of misleading diagnosis.

CT Findings after Laryngectomy

The goal of surgical treatment of laryngeal cancer is to achieve tumor control while preserving, whenever possible, the three primary functions of the larynx: breathing, swallowing, and phonation. The surgical procedure may consist of either a partial, conservative excision (eg, cordectomy, vertical partial laryngectomy, horizontal supraglottic laryngectomy, supracricoid laryngectomy with cricohyoidopexy or cricohyoidoepiglottopexy, or near total laryngectomy) or a radical excision (total laryngectomy). The procedure depends largely on the location and extension of the tumor, the stage of disease, and the patient's needs and preferences. Familiarity with the typical imaging appearance of the larynx after each procedure is crucial for differentiating normal postsurgical changes from persistent or recurrent disease as well as for diagnosing associated second primary malignancies. Since computed tomography (CT) is often used for follow-up evaluations, an ability to interpret the characteristic CT features is particularly important.

Multidimensional Assessment of Voice After Vertical Partial Laryngectomy: A Comparison With Normal and Total Laryngectomy Voice

The aim of this cross-sectional cohort study was to analyze the acoustic, stroboscopic, and perceptual parameters in patients who had undergone vertical partial laryngectomy (VPL) and to compare them with normal subjects (N) and total laryngectomy (TL) patients. This study was carried out in a tertiary referral Cancer Services Centre. We analyzed data from a total of 51 individuals; six VPL patients, 27 TL patients, and 18 N subjects. Acoustic analysis and videostroboscopy were performed using a computerized speech studio. Perceptual analysis was carried out using the GRBAS scoring system. The mean ages in the three groups were 40.9+/-13.5 (N), 54.3+/-9.5 (VPL), and 63.9+/-10.5 years (TL). Acoustic analysis yielded the following results for N, VPL, and TL, respectively: median fundamental frequency (155.2, 224.9, 106.3 Hz), shimmer (0.6, 1.9, 1.3 dB), and jitter (0.3%, 3.3%, 4.2%). The median maximum phonation time was 21.8 (N), 9.4 (VPL), and 10.3 seconds (TL). The median words per minute (WPM) were 168.5 (N), 126 (VPL), and 127 WPM (TL). Acoustic analysis of VPL voice was significantly different from normal voice (Mann-Whitney, P<0.05) and approximated better to TL parameters. The results of TL and VPL groups show poorer values and larger variability for nearly all the quantitative measures as compared to N subjects. Videostroboscopy demonstrated variable level and amount of closure of the vibrating segment in the reconstructed larynx of the VPL group. VPL GRBAS scores were similar to TL scores with good interrater reliability. The multidimensional assessment of voice in VPL patients is significantly worse than in N subjects and more closely resembles that of patients who have undergone TL with surgical voice restoration.

The Impact of the Glottic Configuration After Frontolateral Laryngectomy on the Perceptual Voice Analysis: A Preliminary Study

After the surgical treatment for early glottic carcinoma, the patients end up with voice disturbances in different grades. The aim of this study was to characterize the laryngeal configuration regarding the anterior commissure synechia and its relationship to the perceptual vocal quality. Twenty-five patients underwent frontolateral vertical partial laryngectomy and reconstruction with bipedicle sternohyoid muscle flap resulting from T1b/T2 glottic squamous cell carcinoma from January 1996 to December 2004. Of the 25 patients, 24 were male with a median age of 61 years. The patients were free of disease and the evaluation was performed after a minimum postoperative period of 12 months. Measurements of the anterior commissure synechia and the free border of both vocal folds were simultaneously performed with the perceptual analysis of the voice through GRBAS scale. We calculated the mathematical proportion between the midsagittal dimension of the synechia of the anterior commissure and the measurement of the free border of the intermembranous region of each vocal fold. The higher the relative measurement of the anterior commissure synechia, the worse the overall grade of hoarseness (G) for both vocal folds (P<0.001), the worse the roughness (R) for both vocal folds (P<0.001), and the worse the strained quality (S) for both the reconstructed (P=0.0086) and the preserved (P=0.0026) vocal folds. These results suggest that the relative measurement of the anterior commissure synechia is a crucial factor worsening voice quality and that the perceptual analyses score has a strong correlation to the synechia's impact.
