Subtotal laryngectomy: outcomes of 469 patients and proposal of a comprehensive and simplified classification of surgical procedures

Partial Horizontal Supracricoid Laryngectomy: Which Factors Impact on Post-decannulation Swallowing Outcomes? A Prospective Single-Center Experience

Early decannulation, performed within the first ten days after supracricoid partial laryngectomy, can result in a more rapid recovery of swallowing function with a semisolid bolus in the short term, about 30 days. We selected 20 patients with squamous cell carcinoma of larynx, who underwent supracricoid laryngectomies: 10 cricohyoidopexy (CHP) and 10 cricohyoidoepiglottopexy (CHEP). Staging was pT2 (10 pts), and pT3 (10 pts). Fiberoptic endoscopic evaluation of swallowing was used to assess postoperative swallowing function after a mean of 12 and 22 days from surgery. A modified PAS score (penetration-aspiration scale) was assigned for subtotal laryngectomies. Decannulation occurred after 6.7 ± 2.1 days. Univariate analysis showed that the type of surgery (CHP or CHEP), pT, resection of one arytenoid, and decannulation time are significantly associated with the 12-day PAS score. The 22-day PAS score is significantly associated with only 3 variables: type of surgery, pT, and resection of one arytenoid. From the data presented, the factors that most delay an effective recovery of swallowing are T3 and the resection of one arytenoid. Early decannulation has been shown statistically to improve PAS score in the short term, but not in the long term.

Phonosurgical Injection Approaches for Voice Restoration After Open Partial Horizontal Laryngectomies: A Pilot Study

OBJECTIVE

The aim of the present study is to evaluate the efficacy of phonosurgical corrective approaches based on injection laryngoplasties and pharyngoplasties followed by speech therapy for voice restoration after unsatisfactory phonatory results of open partial horizontal laryngectomies.

METHODS

Ten patients with not satisfying phonatory results despite speech therapy after type II or type III open partial horizontal laryngectomies (OPHLs) were included. Each patient underwent a voice restoration program based on phonosurgery (injection laryngoplasty and/or injection pharyngoplasty) with hyaluronic acid and/or calcium hydroxyapatite, followed by post-surgical voice rehabilitation. Voices were recorded and analysed through spectrographic, aerodynamic, perceptual, laryngoscopic and self-assessment evaluations before the treatment (T0), after 1 month (T1) and after three months (T2).

RESULTS

Significant improvements in the patients voices were found between T0, T1 and T2 concerning acoustic, perceptual, aerodynamic, laryngoscopic and self assessment evaluations.

CONCLUSIONS

The results of the present study support phonosurgical injection procedures followed by speech therapy as an effective strategy for voice restoration after type II or type III OPHLs in selected patients.

Oncological Outcomes of Primary vs. Salvage OPHL Type II: A Systematic Review

Background: Open partial horizontal laryngectomy type II (OPHL type II) has two main aims: oncological radicality and laryngeal preservation. The aim of this review is to define and emphasize the oncological efficacy of OPHL type II, both as primary and salvage surgery, by analyzing the latest literature. Methods: The research was carried out on Pubmed, Scopus and Web of Science databases, by using strict keywords. Oncological outcomes were evaluated by the following parameters: overall survival, disease-specific survival, disease-free survival, local control, laryngeal preservation, local recurrence. Results: The review included 19 articles divided into three groups: (1) primary OPHL type II, (2) salvage OPHL type II, (3) adjuvant radiotherapy after primary OPHL type II. The articles showed excellent results as far as oncological radicality and organ preservation. Conclusions: This review demonstrated that OPHL type II is useful to obtain oncological radicality both as primary surgery and salvage surgery. Nevertheless, the only criterion that determined the positive outcome and efficacy of this technique is the strict selection of patient and tumor.

Upfront surgical organ-preservation strategy in advanced-stage laryngeal cancer

PURPOSE

Advanced-stage laryngeal cancer is a challenging disease that needs multimodal treatment. Medical and surgical organ-preservation strategies have been developing in the last decades to spare these functions while granting cancer cure. The current work presents the experience of a tertiary-care center in conservative surgery for advanced-stage laryngeal cancer.

MATERIALS AND METHODS

We collected clinical data of patients submitted to open partial horizontal laryngectomies (OPHLs) and any possible adjuvant treatment from 2005 to 2018. Outcomes were also compared to the most recent studies reporting on both medical and surgical organ-preservation strategies.

RESULTS

One hundred ten patients were included in the analysis. Adjuvant therapy was employed in 51% of cases. The local control rate was 96.4%, while overall survival (OS) was 67%, and laryngo-esophageal dysfunction free survival (LEDFS) was 66%. Stage IV and vascular invasion were associated with a statistically-significant worse survival.

CONCLUSIONS

OPHLs are valid as upfront treatment in fit patients affected by advanced-stage laryngeal cancer. Disease control and function preservation are granted in a significant percentage of cases, even when followed by adjuvant therapy.

The effect of tracheostomy on swallowing function in open partial horizontal laryngectomies: preliminary experience

OBJECTIVE

Tracheostomy is required to ensure a safe airway in open partial horizontal laryngectomies. The presence of the tracheostomy tube can contribute to post-operative dysphagia. This study aimed to evaluate the effects of a circumferential tracheostomy technique on swallowing.

METHODS

A retrospective study was conducted of patients who underwent open partial horizontal laryngectomies between April 2018 and June 2019. Patients were divided into two groups based on the tracheostomy technique: group 1 had two stitches from the inferior tracheal ring to the skin; group 2 had circumferential fixation of the trachea to the skin. Demographic information, surgical data, post-operative rehabilitation course and complication details were collected and analysed.

RESULTS

Twenty-four patients were enrolled. Patients in group 2 had significant improvement in the initial phases of swallowing rehabilitation.

CONCLUSION

Tracheostomy with anchorage of the trachea to the skin by circumferential stitches could allow early removal of the tracheal tube, with a better swallowing outcome.

Failure of OPHL type IIb due to undiagnosed Eagle syndrome

A 52-year-old man with glottic-supraglottic tumour underwent open partial horizontal laryngectomy (OPHL) IIb. On the 12th day postoperative, laryngoscopy showed necrotic tissue at the level of pexy and an increased distance between tongue base and neoglottis; the neck CT showed cricoid arch rupture and rupture of the pexy. By re-examining the preoperative CT images, the ossification of stylohyoid ligament (Eagle syndrome) was detected and supposed as the possible cause of cricoid rupture due to its traction on the hyoid bone and therefore on the pexy. The stylohyoid ligaments were cut at their insertion on the hyoid bone and a tracheohyoidopexy was performed. Two months after surgery, the patient had only some swallowing impairments. This case represents a complication in OPHL II never reported in literature caused by an undiagnosed Eagle syndrome in preoperative, pointing out the importance to search for any anatomical anomaly that could jeopardise the success of the surgery.

Preoperative prognostic factors for functional and clinical outcomes after open partial horizontal laryngectomies

BACKGROUND

In minority of cases, the clinical recovery of the neolarynx after open partial horizontal laryngectomies (OPHLs) can be challenging, possibly affecting the final functional outcome.

METHODS

One hundred and twenty-three patients who underwent OPHLs were selected. A series of clinical preoperative independent variables were considered. All patients were monitored for the following dependent outcome variables: sequelae; need for percutaneous endoscopic gastrostomy positioning; days before tracheal cannula removal and nasogastric tube removal; and length of hospital stay. Univariate and multivariate logistic regression analyses were performed to identify significant associations between preoperative clinical variables and outcomes variables.

RESULTS

Multivariate analysis confirmed age, cT classification, body mass index, and smoking habits as significant prognostic factors for worse functional and clinical recovery outcomes.

CONCLUSIONS

Knowing what variables are significantly associated with worse clinical and functional outcomes can guide clinicians in defining the best surgical choice not only from an oncological perspective, but also for a better postoperative recovery.

Supracricoid Partial Laryngectomy: Oncological and Functional Outcomes

Introduction In the present study, we have reviewed the outcomes of patients with supracricoid partial laryngectomy (SCPL) in our institution. Our results show that SCPL is a well-tolerated procedure with generally good functional outcomes for patients with advanced laryngeal cancer.

Objective We analyzed the oncological and functional results of a cohort of 35 patients who had undergone SCPL, and we highlighted the complications, identified the overall and disease-free survivals, demonstrating that the reconstructive laryngectomy guarantees the oncological safety and reproducibility of the oncological results, preserving the laryngeal functions and promoting an improvement in the patient's quality of life, favoring communication and interpersonal relationships.

Methods Between 2010 and 2018, 35 patients underwent SCPL for primary and recurrent laryngeal squamous cell carcinomas, and they were divided into two subgroups: in 16 cases, the cricohyoidoepiglottopexy according to the Mayer-Piquet technique was performed, while the remaining 19 cases were submitted to the cricohyoidopexy according to the Labayle technique. In addition to evaluating the oncological results of patients undergoing reconstructive laryngectomy, the present study also aimed to evaluate the functionality of the residual larynx and the quality of life.

Results The overall and disease-free survivals were of 83% and 76.3% respectively. All patients were able to swallow. The nasogastric tube was removed after a mean period of 21.8 days (range: 14 to 28 days). The mean decannulation time was of 23.4 days after surgery (range: 15 to 36 days).

Conclusion The curves for the overall and disease-free survivals show that SCPL can guarantee oncological safety comparable to that of total laryngectomies in diseases in the intermediate stage and in carefully-selected advanced stages.

Salvage surgery for residual or recurrent laryngeal squamous cell carcinoma after (Chemo)radiotherapy: Oncological outcomes and prognostic factors

Nonsurgical primary treatment of early and advanced laryngeal squamous cell carcinoma, employing radiotherapy with or without chemotherapy, is considered a standard of care in many centers throughout the world. When patients have persistent or recurrent disease after non-surgical treatment, salvage surgery is frequently the only remaining potentially curative treatment. Depending on the extent of the residual/recurrent disease, different surgical salvage options are at the surgeon's disposal. In selected cases with limited local disease, salvage transoral laser microsurgery, transoral robotic surgery and open partial laryngectomies can be employed to achieve cure while preserving laryngeal function. For more advanced cases total laryngectomy is necessary. Identifying situations with unacceptable results from surgical salvage may guide future therapies.

Patterns of recurrence after open partial horizontal laryngectomy types II and III: univariate and logistic regression analysis of risk factors

In choosing the best surgical treatment (total or partial laryngectomy) for patients affected by laryngeal squamous cell carcinoma (SCC), it is still necessary to identify a link between prognostic factors and oncological outcomes. A retrospective analysis of clinical outcomes of 819 patients affected by laryngeal cancer who underwent OPHL type II and III between 1995 to 2014 was carried out. Focusing on recurrence and its site (local, regional or distant), our cohort has been divided in two groups: patients showing recurrence (n = 108) vs those without recurrence (n = 711). Thirteen clinical-pathological parameters have been studied by univariate and multivariate analysis to identify possible correlations between recurrence and oncological outcomes (overall survival (OS), disease free survival (DFS), disease specific survival (DSS), laryngectomy free survival (LSF), laryngectomy free freedom (FFL). In multivariate analysis, we found 4 negative prognostic factors for recurrence: site of tumour (> supraglottic), cartilage invasion (> if present), perineural invasion (> if present) and type of OPHL (> in OPHL type III). The knowledge and detection of negative prognostic factors for the risk of recurrence (pN classification, cartilage involvement, perineural invasion, and thus the type of surgical treatment adopted) could increase the already well-established potentiality of OPHLs in treating cases with a safe indication after careful discussion in the tumour board.

The Penetration-Aspiration Scale: Adaptation to Open Partial Laryngectomy and Reliability Analysis

A standard for assessing swallowing function after open partial horizontal laryngectomy (OPHL) is still not established. The variability in the measures used to investigate swallowing functional outcomes after OPHL limits the communication among clinicians and the possibility to compare and combine results from different studies. The study aims to adapt the PAS to the altered anatomy after OPHLs using fiberoptic endoscopic evaluation of swallowing (FEES) and to test its reliability. To adapt the PAS, two landmarks were identified: the entry of the laryngeal vestibule and the neoglottis. Ninety patients who underwent an OPHL were recruited (27 type I, 31 type II and 32 type III). FEES was performed and video-recorded. Two speech and language therapists (SLTs) independently rated each FEES using the PAS adapted for OPHL (OPHL-PAS). FEES recordings were rated for a second time by both SLTs at least 15 days from the first video analysis. Inter- and intra-rater agreement was assessed using unweighted Cohen's kappa. Overall, inter-rater agreement of the OPHL-PAS was k = 0.863, while intra-rater agreement was k = 0.854. Concerning different OPHL types, inter- and intra-rater agreement were k = 0.924 and k = 0.914 for type I, k = 0.865 and k = 0.790 for type II, and k = 0.808 and k = 0.858 for type III, respectively. The OPHL-PAS is a reliable scale to assess the invasion of lower airway during swallowing in patients with OPHL using FEES. The study represents the first attempt to define standard tools to assess swallowing functional outcome in this population.

Supratracheal laryngectomy: a multi-institutional study

Introduction

Supratracheal laryngectomy has been described as a surgical procedure for glottic or supraglottic cancer extending to the subglottic region and/or involving the cricoarytenoid joint, aiming to preserve laryngeal function (breathing, phonation and swallowing), without diminishing locoregional cancer control. The choice of supracricoid laryngectomy in these cases could result in a high risk of compromised resection margins.

Objective

To determine the safety, viability, adequacy of surgical margins and the supratracheal laryngectomy results for intermediate and advanced laryngeal cancer by reviewing the results at three different institutions in Brazil.

Methods

This is a retrospective study that analyzed the charts of 29 patients submitted to supratracheal laryngectomy from October 1997 to June 2017. The type of laryngectomy performed was classified according to the European Laryngological Society classification for horizontal laryngectomies. Early and late results were evaluated. Survival rates (overall, specific, disease-free and total laryngectomy-free survival) were calculated. The mean follow-up time was 44 months.

Results

Of the 29 patients submitted to supratracheal laryngectomy, 25 had no previous treatment. One patient (3.4%) had compromised margins. Four patients (13.8%) had recurrence. Of these, three had local recurrence and one had regional recurrence. Five patients (17.2%) required a total laryngectomy, two due to ruptured pexy and three due to local recurrence. Four of these patients (80%) achieved a successful total procedure. Four patients (13.8%) died, two due to postoperative complications and two due to recurrence. Overall, specific, disease-free and total laryngectomy-free survival at 5 years were, respectively, 82.1%; 88.2%; 83.0% and 80.2%.

Conclusion

Selected patients with intermediate and advanced laryngeal cancer may benefit from supratracheal laryngectomy, that resulted in total laryngectomy-free survival and specific survival of 80.2% and 88.2%, respectively.

Limitations and Opportunities in Open Laryngeal Organ Preservation Surgery: Current Role of OPHLs

The current trend for treatment of intermediate-early advanced laryngeal cancer is essentially oriented toward preservation of organ and laryngeal function, and with a good potential for treating the disease. This goal can be achieved by adopting open laryngeal organ preservation surgery (OLOPS), at present mainly represented by open partial horizontal laryngectomies (OPHLs). An approach using rigorous selection criteria based on both the general condition of the patient and the local and regional extent of the disease gives excellent oncological and functional results in untreated patients. Similar outcomes, albeit slightly worse, are also obtainable in radio-recurrent and laser-recurrent patients. Troublesome postoperative management and the inconsistency of functional recovery are the main limitations for extensive application of this therapeutic strategy. The future direction is represented by simplification of the indications identifying iso-prognostic sub-categories within the T-stage, wider consensus on rehabilitation protocols, hybrid approaches to the larynx, and open minimally invasive access.

Salvage open partial horizontal laryngectomy after failed radiotherapy: A multicentric study

OBJECTIVES

The primary aim of the present study was to report our multi-institutional experience in surgical salvage with open partial horizontal laryngectomies (OPHL) after failed radiotherapy (RT) for laryngeal squamous cell carcinoma (LSCC). Secondary aims were to analyze the prognostic meaning of the main clinical and pathological parameters in relation to the oncologic outcome and to compare our results with the available literature.

STUDY DESIGN

A retrospective multicenter analysis of surgical oncological outcomes.

METHODS

We retrospectively review the clinical charts of 70 recurrent LSCC patients after primary RT failure undergone salvage OPHL.

RESULTS

At last follow-up, 46 patients (65%) were disease-free; six (9%) were alive with disease; nine (12%) died because of the disease; and nine (12%) died without evidence of disease. The final local control, overall survival, disease-specific survival, and laryngectomy-free survival were 87%, 75%, 87%, and 91%, respectively. Twelve patients (17%) experienced postoperative complications, whereas 18 patients (25%) experienced late sequelae. In five patients (7%), decannulation was not possible because of postoperative laryngeal stenosis.

CONCLUSION

In selected patients, when proper selection criteria for conservation laryngeal surgery are adopted, OPHL can be considered for salvage after RT failure.

Matched-pair analysis of survival in the patients with T3 laryngeal squamous cell carcinoma treated with supracricoid partial laryngectomy or total laryngectomy

Background

The survival outcomes between supracricoid partial laryngectomy (SCPL) and total laryngectomy (TL) were compared in the groups of matched-pair patients with T3 laryngeal squamous cell carcinoma (LSCC).

Methods

Patients with T3 LSCC were matched based on prognostic factors. The Kaplan–Meier curve and the Cox proportional hazards model were used for analysis on survival.

Results

A total of 212 patients with T3 LSCC were included after matching (106 underwent SCPL and 106 underwent TL). Multivariable analysis showed no differences in overall survival (hazard risk [HR]=1.15; 95% CI: 0.79–1.67; P=0.47), disease-specific survival (HR=1.11; 95% CI: 0.69–1.80; P=0.66), and recurrence-free survival (HR=1.07; 95% CI: 0.68–1.68; P=0.77) between the SCPL group and TL group.

Conclusion

SCPL provides reliable therapeutic outcomes and can be used to avoid a TL surgery in some patients with advanced primary laryngeal cancer.

Supracricoid laryngectomy for recurrent laryngeal cancer after chemoradiotherapy: a systematic review and meta-analysis

Residual or recurrent laryngeal cancer after irradiation is a difficult clinical problem with a rate that ranges from 13% to 36% of cases. Supracricoid laryngectomy (SCL) with cricohyoidopexy (CHP) or cricohyoidoepiglottopexy (CHEP) provide reliable oncological and functional results for selected primary and recurrent patients with glottic and supraglottic carcinomas. We conducted a systematic review and meta-analysis to assess the oncological and functional outcomes of patients treated with open partial horizontal laryngectomy types IIa and IIb (CHEP, CHP) in terms of the recurrence of squamocellular cancer of the larynx after radiotherapy failure. The databases searched included MEDLINE, PubMed and EMBASE (from January 1990 to December 2015, English language). The meta-analysis was performed with a mixed random effects model using the DerSimonian and Laird method. The heterogeneity was measured with the I² statistic. Fourteen papers out of 276 were included and comprised a total of 291 patients. The five-year overall survival was 80.2% (CI 0.719-0.885; I² = 62%; p = 0.003), and the 5-year disease-free survival was 89.5% (CI 0.838-0.952; I² = 52%; p = 0.022). The indications for SCL after the failure of radiation therapy (RT) were similar to those specified for previously untreated patients. We therefore hypothesised that careful assessment of tumour extension might be responsible for the high 5-year OS and 5-year DFS. The early postoperative recovery outcomes indicated that the mean time until decannulation was 35.6 days (CI 24.3-46.9; I² = 95%; p < 0.001), and the mean time until nasogastric tube (NGT) or percutaneous endoscopic gastrostomy (PEG) removal was 28.3 days (CI 22.7-33.8; I² = 86%; p< = 0.001). These data are according to authors who prefer the initial removal of the NGT and the initiation of oral alimentation with a tracheostomy tube to protect and clean the airways and permit the suction of any residual food that might be present.

Lateral cervical approach for supracricoid partial laryngectomy

INTRODUCTION

The supracricoid partial laryngectomy has been described for the treatment of T3 laryngeal glottic and supraglottic tumors as well as upfront and salvage surgery. Good oncological and functional outcomes are expected, while the post-operative rehabilitation can be quite difficult for the patient. Early and late complications can occur especially in salvage surgery. Neck dissection according to the T stage is often associated with the resection of the primary tumor.

OBJECTIVE

To verify the feasibility of a minimally invasive procedure for supracricoid partial laryngectomy by adopting the lateral cervical approach.

METHODS/RESULTS

A 61-year old man affected by a cT3N0 glottic cancer already treated 10years prior with radiotherapy for oropharyngeal cancer underwent supracricoid laryngectomy using the lateral approach. The key point of the procedure was a subfascial dissection with the harvesting of anterior cervical flap including skin, fat, platysma, fascia superficialis, anterior jugular veins, homo- and sterno-hyoid muscles.

CONCLUSION

Supracricoid laryngectomy by a lateral approach is feasible and safe; it allows to perform a simultaneous neck dissection and the removal of the entire laryngeal specimen preserving ample healthy tissue compared to the classic anterior approach.

Unravelling the risk factors that underlie laryngeal surgery in elderly

Older patients are not considered good candidates to undergo more challenging therapeutic treatments, e.g. highly invasive surgery and complex chemotherapy. However, their exclusion from standard therapeutic options is not justifiable. Herein, we reviewed 212 patients aged ≥ 70, affected with laryngeal squamous cell carcinoma, and treated with transoral laser microsurgery or open neck (partial / total) laryngectomy with radical intent. The main aim was to compare patient outcomes to identify predictive factors that can be used by surgeons to choose the most appropriate treatment option. In our cohort, patients affected with more advanced tumour and hence treated by invasive open neck surgeries (above all TL) are more prone to develop complications and undergo fatal outcome than those with early disease treated by laser microsurgery, independently of age at surgery. In conclusion, elderly patients affected by laryngeal cancer can be treated similarly to younger patients, keeping in mind that more invasive surgeries are associated with a higher risk of developing complications. The advantages of mini-invasive surgery make it a possible first choice treatment in very old and frail patients suffering from laryngeal cancer, especially considering the recent success in treatment of some advanced stage tumours. Furthermore, comorbidities, by themselves, should not be used as exclusion criteria for subjecting an elderly patient to a different treatment that is from standard therapy.

Open partial horizontal laryngectomies: is it time to adopt a modular form of consent for the intervention?

Nowadays, open partial horizontal laryngectomies (OPHLs) are well-established procedures for treatment of laryngeal cancer. Their uniqueness is the possibility to modulate the intervention intraoperatively, according to eventual tumour extension. An OPHL procedure is not easy to understand: there are several types of procedures and the possibility to modulate the intervention can produce confusion and lack of adherence to the treatment from the patient. Even if the surgery is tailored to a patient's specific lesion, a unified consent form that discloses any possible extensions, including a total laryngectomy, is still needed. We reviewed the English literature on informed consent, and propose comprehensive Information and Consent Forms for OPHLs. The Information Form is intended to answer any possible questions about the procedure, while remaining easy to read and understand for the patient. It includes sections on laryngeal anatomy and physiology, surgical aims and indications, alternatives to surgery, complications, and physiology of the operated larynx. The Consent Form is written in a "modular" way: the surgeon defines the precise extension of the lesion, chooses the best OPHL procedure and highlights all possible expected extensions specific for the patient. Our intention, providing these forms both in Italian and in English, is to optimise communication between the patient and surgeon, improving surgical procedure arrangements and preventing any possible misunderstandings and medico-legal litigation.

Telephonic voice intelligibility after laryngeal cancer treatment: is therapeutic approach significant?

The aim was to investigate telephonic voice intelligibility in patients treated for laryngeal cancer using different approaches. In total, 90 patients treated for laryngeal cancer using different approaches and 12 healthy volunteers were recruited. Each patient and each healthy control read a list of words and sentences during a telephone call. Six auditors listened to each telephonic recording and transcribed the words and sentences they understood. Mean intelligibility rates for each treatment were assessed and compared. Regarding words, the poorest intelligibility was noted for type II open partial horizontal laryngectomies, followed by total laryngectomies. The best intelligibility was found for transoral laser microsurgery, followed by radiotherapy alone. For sentences, the poorest intelligibility was noted for type II open partial horizontal laryngectomies, followed by chemoradiotherapy. The best intelligibility was found for radiotherapy alone and transoral laser microsurgery. More aggressive surgery as well as chemoradiotherapy correlated with significantly poorer outcomes. Transoral laser microsurgery or radiotherapy alone ensured the best telephonic voice intelligibility. Intermediate-advanced T stages at diagnosis also showed significantly poorer intelligibility outcomes, suggesting that T stage represents an independent negative prognostic factor for voice intelligibility after treatment.

Re-Evaluation of Open Partial Horizontal Laryngectomies at Our Institution According to the New Classification Recommended by the European Laryngological Society

Objective

The aim of this study was to re-evaluate the open partial horizontal laryngectomies (OPHLs) performed at our institution in terms of the new classification of the European Laryngological Society and compare the differences with the new classification system.

Methods

A retrospective analysis of 45 patients diagnosed with T1b, T2, and T3 laryngeal carcinoma who were treated with OPHLs in our department between 2010 and 2016 were conducted.

Results

All supraglottic laryngectomies (31 operations) were classified as OPHL Type 1. Among these, 11 operations required a resection of an additional structure including arytenoid (ARY) in five operations, piriform sinus (PIR) in four operations, the base of tongue (BOT) in one surgery, and ARY + PIR in one patient. Five supracricoid laryngectomies with cricohyoidoepiglottopexy (CHEP), five supracricoid laryngectomies with cricohyoidopexy (CHP), and four near-total laryngectomy operations constituted Type 2 OPHL (7 operations) and Type 3 OPHL (7 operations). Among these operations, two were classified into Type 2b OPHL and four into Type 3b OPHL as the superior margin of incision included epiglottis.

Conclusion

We consider that, this new classification, because it allows understanding the content of the surgery from the related title, will be useful in comparing different series and techniques.

Long-term functional results after open partial horizontal laryngectomy type IIa and type IIIa: A comparison study

BACKGROUND

The purpose of this study was to compare long-term swallowing, voice results, and quality of life (QOL) after open partial horizontal laryngectomy (OPHL) type IIa and type IIIa.

METHODS

Twenty-three patients after OPHL type IIa and 18 patients after OPHL type IIIa were involved. Swallowing skills and neoglottis' motility and vibrations were videoendoscopically assessed. Aerodynamic measures, spectrogram analysis, aspiration pneumonia, body weight variations, and voice perceptual assessment were performed. Generic voice-related and swallowing-related QOL were assessed. Data were statistically compared using Mann-Whitney U test or Fisher exact tests, as appropriate.

RESULTS

Significant differences were found only for the residue with solids and for the intelligibility (I) parameter of the overall quality impression and intelligibility, additive and unnecessary noise, speech fluency, and presence of voiced segments scale with patients of the OPHL type IIIa group showing worse performances than the OPHL type IIa group.

CONCLUSION

Patients who underwent OPHL type IIa and type IIIa show comparable long-term functional outcomes. OPHL type IIIa represents a valid surgical alternative to OPHL type IIa. © 2015 Wiley Periodicals, Inc. Head Neck 38: E1427-E1435, 2016.

[Histopathological evaluation of the subtotal laryngectomy specimen]

INTRODUCTION

The goal of conservative surgical treatment of laryngeal cancer is to obtain oncological control with preservation of laryngeal function. The concept of laryngeal function preservation should be understood as the preservation of the patient's ability to breathe normally with neither tracheostomy nor aspiration, and maintaining intelligible speech. This can be achieved by a balance between two fundamental aspects, proper patient selection (based on tumour extension and preoperative laryngeal function), and an adequate histopathological analysis of the surgical specimen. Supracricoid subtotal laryngectomy is the voice conservative surgical technique that offers the best possibility of control in patients with locally advanced laryngeal cancer. The proper histopathological analysis allows staging and selecting patients for adjuvant therapy, avoiding unnecessary ones as well as designing monitoring and surveillance programs based on risk factors.

OBJECTIVE

To highlight key points in the histopathological evaluation of the surgical specimen of a subtotal laryngectomy.

CONCLUSION

The proper communication between the surgeon and pathologist, offering complete information on preoperative clinical evaluation and the knowledge of the key points in the evaluation of the surgical specimen (sites of tumour leakage and surgical resection margins) are fundamental parameters to achieve a proper histopathological evaluation of the surgical specimen.

Quality of Life After Conservation Surgery for Laryngeal Cancer

Quality of life preservation has become an essential goal of treatment in the management of laryngeal carcinoma. Although established treatments of reference such as total laryngectomy and chemoradiation protocols have focused on survival and anatomic preservation of the larynx, they still generate considerable functional morbidity with detrimental effects on quality of life. Transoral and transcervical partial laryngectomy techniques can offer significant advantages when used prudently after proper patient selection. The growing relevance of those techniques in the management of advanced and recurrent laryngeal carcinoma deserves particular attention, with potential for improved quality of life without compromising oncologic outcomes.

Benefits and drawbacks of open partial horizontal laryngectomies, Part A: Early- to intermediate-stage glottic carcinoma

BACKGROUND

Laryngeal squamous cell carcinoma (SCC) accounts for 1.9% of cancers worldwide. Most of these are diagnosed in the early stages (T1-T2, and N0). For these, a larynx preserving/conserving option is preferable. Beyond transoral laser microsurgery (TLM), open partial horizontal laryngectomy is a function-sparing surgical technique used to treat laryngeal SCC.

METHODS

We retrospectively analyzed the clinical outcomes of 216 patients who underwent open partial horizontal laryngectomy for glottic cT2 laryngeal cancer.

RESULTS

Five-year overall survival (OS), disease-specific survival (DFS), locoregional control, local control, laryngeal function preservation, and laryngectomy-free survival rates were 93.1%, 98.0%, 97.1%, 97.5%, 97.8%, and 98.5%, respectively. Disease controls were significantly affected by previous treatment and type of surgery used.

CONCLUSION

Although TLM for cT2 laryngeal cancer with unimpaired vocal cord mobility still represents a sound option, open partial horizontal laryngectomy offers higher local control and laryngeal preservation rates for selected patients with impaired mobility of vocal cords combined with involvement of the paraglottic space. © 2015 Wiley Periodicals, Inc.

Swallowing, voice, and quality of life after supratracheal laryngectomy: preliminary long-term results

BACKGROUND

The purpose of this study was to report preliminary long-term outcomes after supratracheal laryngectomy (STL).

METHODS

Twenty-two male patients who underwent STL were involved in this study. Swallowing skills, neoglottis motility, and vibrations were videoendoscopically assessed. Aerodynamic measures, spectrogram analysis, aspiration pneumonia, body weight variations, and voice perceptual assessment were performed. Generic, voice-related, and swallowing-related quality of life (QOL) were assessed.

RESULTS

Aspiration was found in 10, 2, and 5 patients, respectively, for liquids, semisolids, and solids. Neoglottis motility was generally preserved, whereas vibration was impaired. Aerodynamic measures showed a poor performance. Perceptual assessment revealed highly dysphonic voices. In only 8 patients, a harmonic structure was visible in the spectrograms. Aspiration pneumonia occurred in 2 patients. Preoperative weight was maintained in 16 patients. Generic, voice-related, and swallowing-related QOL revealed satisfied patients.

CONCLUSION

After STL, swallowing was sufficiently restored and QOL was satisfactory, whereas the voice was severely impaired even if oral communication was well preserved.

Analysis of swallowing after partial frontolateral laryngectomy with epiglottic reconstruction for glottic cancer

The aim of the study was to evaluate swallowing using a reproducible objective methodology and to seek preoperative factors that could influence swallowing outcomes in patients operated on for partial laryngectomy. Twenty-four patients who underwent partial frontolateral laryngectomy with epiglottic reconstruction for T1bN0 or T2N0 glottic carcinoma between 2008 and 2012 were retrospectively evaluated. Using fiberoptic endoscopic and videofluoroscopic evaluation, early (15 days postoperatively) and late (2 months postoperatively) scores were obtained for all patients to quantify their swallowing skills. Eighty-three percent of patients achieved at least partial oral feeding at time of hospital discharge and 87.5% achieved exclusive oral feeding within 2 months postoperatively. Early score was good or excellent in 50%, average in 4.2% and poor in 41.8%. Regarding late scores, 63% were classified as having a good or excellent late score, 7 patients (29%) were classified as "middle result" because their time to recover was longer (i.e. between 1 and 2 months postoperatively), and two patients had a poor late score. Finally, at last follow-up, only one patient was partially fed by gastrostomy (180 days after surgery). T stage (p = 0.04) was the only factor influencing early swallowing outcomes and length of hospital stay was longer for poor scores than for good late results (p = 0.02). Our findings show good outcomes in terms of postoperative swallowing. Objective assessment of deglutition is essential for a better understanding of the mechanisms of postoperative swallowing disorders and for patient selection.
