RESUMO
OBJECTIVES: Trans-nasal humidified rapid insufflation ventilatory exchange (THRIVE) has demonstrated utility in extending the apneic window in the perioperative setting. Its benefits in facilitating tubeless anesthesia are recognized during elective laryngotracheal surgeries. The use of THRIVE and administering higher fractional inspired oxygen concentrations in laser laryngeal surgery (LLS) remains controversial due to the theoretical risk of airway fires. A scoping review of the literature describing institutional experiences with THRIVE during LLS was conducted. DATA SOURCES AND REVIEW METHODS: A systematic scoping review of the literature was performed including PubMed, Medline, Embase, Scopus, JBI EBP Database, and Cochrane Library from inception to April 2023. RESULTS: From the 472 articles identified in our review, nine articles were included representing 271 cases. THRIVE was used for preoxygenation and to maintain apneic oxygenation during LLS. Different institutional practices related to THRIVE parameters and intraoperative modifications during lasing were described in the literature, including cessation of THRIVE, reduction of FiO2 to 30%, and continuous 100% FiO2 oxygenation. One study described a brief ignition of the coating of a KTP laser fiber without injury to the patient. No adverse patient outcomes have been documented in the literature with THRIVE during LLS. CONCLUSION: THRIVE is a safe and effective form of tubeless anesthesia and apneic oxygenation during LLS, with no adverse patient safety events reported in the literature. Key determinants to maintain safety include optimal patient and team selection, effective surgeon-anesthetist cooperation, and institutional protocols that govern intraoperative practice.

RESUMO
INTRODUCTION: Patients presenting with head and neck squamous cell carcinoma of unknown primary (HNSCCUP) remain challenging clinical scenarios as large variation exists in practices used to locate the primary. OBJECTIVE: The objective of this systematic review is to review of the literature and offer recommendations for oropharyngeal biopsies in HNSCCUP. METHOD: Pubmed, Medline and Embase were searched to identify studies from inception to October 2021. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed. RESULTS: A total of 483 articles were included and screened, 41 studies met the inclusion criteria, including over 3400 patients from the original articles (122 of these patients were reported on in two sequential articles by a single author - table 1) and 4 large metaanalyses including 1852 patients. The primary site identification rate following random biopsies or deep tissue biopsies is less than 5% in most studies. The mean detection rate following ipsilateral tonsillectomy is 34%; two pooled analyses indicate that the mean detection rate following tongue base mucosectomy is 64%, with this figure rising when the tonsils are negative. CONCLUSIONS: High level evidence is lacking, with heterogeneity in the reported studies. Published meta-analyses are based on retrospective data. There is little evidence supporting the practice of random/non-directed oropharyngeal biopsies. Available evidence supports palatine tonsillectomy and tongue base mucosectomy compared to deep tissue biopsies.

PURPOSE: In early glottic squamous cell carcinoma, similar results have been described in terms of disease control between transoral laser microsurgery (TLM) and radiation therapy (RT). During the past two decades, several studies compared subjective vocal outcomes of exclusive RT with those of TLM, showing a trend towards improving results for TLM over time. However, the objective differences in terms of spectro-acoustic voice parameters between exclusive RT and TLM have been less frequently investigated. The aim of this systematic review with meta-analysis was to evaluate voice quality after TLM and RT treatment for early glottic carcinoma, based on acoustic analysis parameters including jitter, shimmer, noise to harmonic ratio, fundamental frequency and maximum phonation time. MATERIAL AND METHODS: A search of the English published literature was conducted on the Pubmed, Scopus and Cochrane databases following PRISMA guidelines. RESULTS: A total of 441 titles were retrieved from the search. After full-text screening and application of inclusion/exclusion criteria, 12 articles were included. We found no significant differences between TLM and RT treatment in the considered acoustic analysis parameters, except for Shimmer, with more favorable values reported in the RT group. CONCLUSIONS: Considering the spread of the disease and expecting an improvement in long-term survival over time, well-designed and multicentric studies involving larger populations with a long-term follow up are mandatory to better assess objective voice outcomes in terms of spectro-acoustic voice parameters.

PURPOSE: The involvement of the anterior commissure (AC) is regarded to be a risk factor for poor results after transoral laser microsurgery (TLM) for early glottic cancer. The objective of this study was to determine how AC-related clinical and radiological factors affected oncological outcomes in a cohort of patients with T1 stage early glottic carcinoma involving the anterior commissure who were treated with TLM with negative surgical margins. METHODS: Retrospective analysis was performed on clinical, radiological, and follow-up data of patients consecutively treated with TLM at a tertiary academic center between November 2011 and August 2021 for T1 glottic squamous cell carcinoma involving the anterior commissure. Recurrence-free survival (RFS), local control with laser alone (LCL), laryngeal preservation (LP), and overall survival (OS) rates (Kaplan-Meier) were the primary outcome metrics. RESULTS: In our series, 5-year OS probability was 75.1%, RFS was 64.8%, LCL was 73.8%, and LP was 83.4%. OS and RFS were higher in patients with early stages of AC pattern than in patients with advanced stage (p = 0.004, p = 0.034, respectively). Vertical extension ratio was found to be associated with OS and RFS (p = 0.023, p = 0.001, respectively), and thyroid cartilage interlaminar angle with LCL by multiple Cox regression analysis (p = 0.041). CONCLUSION: TLM remains a valuable treatment option for AC involvement. AC3 type involvement and elevated vertical extension ratio were associated with negative prognosis. There have been signs that thyroid cartilage with a narrow angle increases recurrence. Alternative modalities should be kept in mind in the treatment decision of these cases.

OBJECTIVE: The Laryngoscore was described in 2014 as a practical preoperative assessment tool to predict difficult laryngeal exposure (DLE) during transoral approaches to the larynx. In 2019 the authors proposed a version with a reduced number of variables, called the mini-Laryngoscore. We aim to critically appraise and externally validate these two tools and if needed and possible, to optimize these tools. METHODS: 103 consecutive patients who underwent a microlaryngoscopy between November 2017 and June 2020 at the Leuven University Hospitals were prospectively included and subjected to a presurgical evaluation of 15 parameters and a peroperative scoring of the anterior commissure visualization. Subsequent analysis focused on the concordance of our findings with those of Piazza et al., the discriminatory ability of the test, and the validity of the included items. We then evaluated a modified prediction tool. RESULTS: Of 103 patients, 18 (17.5%) had DLE. The Laryngoscore and mini-Laryngoscore predicted this with a "good" C-index of respectively 0.727 (95%CI: 0.608-0.846) and 0.714 (95%CI: 0.605-0.823). A newly created prediction tool including only three parameters (Interincisors gap, upper jaw dental status and previous treatments) showed a better discriminatory ability (C-index = 0.835, 95%CI: 0.726-0.944) than the original Laryngoscore, a finding that needs further external validation. CONCLUSION: The original Laryngoscore and the mini-Laryngoscore displayed a good discriminative ability. Some parameters can be left out of the Laryngoscore without losing discrimination. An even better prediction model seems possible, using a weighted sum of selected predictor variables and by using the parameters in their continuous form.

Transoral laser microsurgery represents the primary surgical modality for early laryngeal cancers with oncologic outcomes equivalent to radiotherapy. Accurate tumor mapping and margin assessment can be difficult, however, particularly during piecemeal or ablative resections, and for tumors with a wider geographic footprint. Tumor-targeted fluorescence-guided surgery in patients with head and neck cancer has empirically improved tumor and margin identification; this case details, for the first time, a fluorescence-guided surgical resection of a T2N0M0 transglottic tumor using panitumumab-IRDye800, an epidermal growth factor receptor monoclonal antibody covalently linked to near-infrared (NIR) dye.

Supraglottic laryngectomy has evolved from open to transoral endoscopic approaches with advancements in surgical techniques and instruments such as lasers, endoscopes, ultrasonic devices, and robotics. Transoral laser-assisted microsurgery has emerged as an effective treatment option, offering faster functional recovery and serving as an alternative to partial laryngectomy or non-surgical therapies. Traditional endoscopic supraglottic laryngectomy involves resection of both suprahyoid and infrahyoid supraglottic structures. However, in cases where the tumor is limited to the infrahyoid epiglottis, a new technique known as transoral laser-assisted infrahyoid supraglottic laryngectomy allows for tumor removal while preserving the suprahyoid epiglottis, aryepiglottic folds, and vallecula, ensuring optimal preservation of laryngopharyngeal function. This procedure enables patients to swiftly return to their daily routines with minimal complications. This article discusses the surgical technique, potential indications, and advantages and disadvantages of the new approach for infrahyoid epiglottic cancer.

PURPOSE: Laser cordectomy is a widely accepted treatment modality for selected cases of early glottic cancers, but its role as a salvage treatment remains unclear. We aimed to investigate the oncological outcomes and failure patterns of salvage cordectomy. MATERIALS AND METHODS: This was a retrospective cohort study of patients who underwent cordectomy for early glottic cancer between 2013 and 2022 at a tertiary referral center. The main outcome measures were overall survival, larynx-preservation rate, tracheostomy dependency rate, and disease-free survival. RESULTS: A total of 142 patients (mean age: 63 years, interquartile range [IQR]: 45-72, 123[86.9 %] males) were analyzed. There were 38 (26.8 %) recurrences after a mean of 22 months (IQR: 17-26). Among them, 25 (17.6 %) underwent salvage cordectomy, while 13 (9.1 %) received other salvage treatments (11[7.7 %] (chemo)radiotherapy and 2[1.4 %] total laryngectomy). In comparison to the other salvage treatments, salvage cordectomy demonstrated lower tracheostomy rates (0 vs. 31 %, p = 0.05), comparable 5-year disease-free survival (62 % vs. 54 %, p = 0.4), higher 5-year larynx preservation rate (92 % vs. 54 %, p = 0.02), and improved 5-year overall survival rate (84 % vs. 62 %, p = 0.01). Factors associated with salvage cordectomy failure were age >60 years (odds ratio [OR]: 1.3, 95 % confidence interval [CI]: 1.15-1.53), smoking continuation (OR: 3.73, 95 % CI: 3.5-4.4), heavy smoking (OR: 1.24, 95 % CI:1.07-2.15), and pT1b + (OR: 2.26, 95 % CI: 2.1-2.9). CONCLUSIONS: Salvage cordectomy offers favorable larynx preservation rates and oncological outcomes for recurrent disease amenable to conservative surgery. Smoking, advanced age, and advanced tumor stages are associated with salvage cordectomy failure.

High-flow nasal cannula (HFNC) is an emerging option for maintaining oxygenation in patients undergoing laryngeal surgery, as an alternative to traditional tracheal ventilation and jet ventilation (JV). However, the data on its safety and efficacy is sparse. This study aims to aggregate the current data and compares the use of HFNC with tracheal intubation and jet ventilation in adult patients undergoing laryngeal surgery. We searched PubMed, MEDLINE (Medical Literature Analysis and Retrieval System Online, or MEDLARS Online), Embase (Excerpta Medica Database), Google Scholar, Cochrane Library, and Web of Science. Both observational studies and prospective comparative studies were included. Risk of bias was appraised with the Cochrane Collaboration Risk of Bias in Non-Randomized Studies - of Interventions (ROBINS-I) or RoB2 tools and the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for case series. Data were extracted and tabulated as a systematic review. Summary statistics were performed. Meta-analyses and trial sequential analyses of the comparative studies were performed. Forty-three studies (14 HFNC, 22 JV, and seven comparative studies) with 8064 patients were included. In the meta-analysis of comparative studies, the duration of surgery was significantly reduced in the THRIVE (Transnasal Humidified Rapid-Insufflation Ventilatory Exchange) group, but the number of desaturations, need for rescue intervention, and peak end-tidal CO2 were significantly increased compared to the conventional ventilation group. The evidence was of moderate certainty and there was no evidence of publication bias. In conclusion, HFNC may be as effective as tracheal intubation in oxygenation during laryngeal surgery in selected adult patients and reduces the duration of surgery but conventional ventilation with tracheal intubation may be safer. The safety of JV was comparable to HFNC.
RESUMO
BACKGROUND: Over the past decade, therapeutic options in head and neck supraglottic squamous cell carcinoma have constantly evolved. The classical total laryngectomy has been partially replaced by alternative organ- and function-sparing techniques with the same prognosis but less morbidity, such as Radiotherapy, Transoral Laser Microsurgery (TLM) and Trans-Oral Robotic Surgery (TORS). Up to now, a prospective comparison of these innovant techniques has not been conducted. METHODS/DESIGN: We will conduct an original international multicentric prospective nonrandomized clinical trial to compare the efficacy between these treatments (Arm 1: Radiotherapy ± chemotherapy; Arm 2: TLM and Arm 3: TORS) with 4 classes of outcomes: quality of life (QoL), oncological outcomes, functional outcomes and economic resources. The population will include cT1-T2 /cN0-N1/M0 supraglottic squamous cell carcinoma. The primary outcome is a Clinical Dysphagia QoL evaluation assessed by the MD Anderson Dysphagia questionnaire. Secondary outcomes include others QoL evaluation, oncological and functional measures and cost parameters. The sample size needs to reach 36 patients per arm (total 108). DISCUSSION: In the current literature, no prospective head-to-head trials are available to compare objectively these different treatments. With the increase of highly efficient treatments and the increase of oncological survival, it is imperative also to develop management strategies that optimize QoL and functional results. We will conduct this innovate prospective trial in order to obtain objective data in these two main issues. TRIAL REGISTRATION: NCT05611515 posted on 10/11/2022 (clinicaltrial.fgov).

Abstract Objective The aim of study was to demonstrate that transcutaneous intralesional injection of Triamcinolone Acetonide (TA) under fibrolaryngoscopy could be an option for persistent granulation after Transoral Laser Microsurgery (TLM) in glottic cancer patients. Methods We recruited 32 patients, who had conservative treatment but failed. 20 patients accepted TA injection monthly until the granulation disappeared or did not shrink further. 12 patients chose to closely monitor. Results For the 20 patients, 17 (85.0%) patients' granulations completely disappeared. 3 (15.0%) patients' granulations had reduced 80%. For the 12 patients, 3 (25.0%) patients' granulations disappeared but 9 (75%) patients' granulations did not have an obvious change. Recurrence was not observed. Conclusion Our experience showed that transcutaneous intralesional TA injection for persistent granulation after TLM through cricothyroid membrane is an efficient, security, harmless and low recurrence method. Especially suitable for huge granulation which blocks the glottis and recur after a second operation.
RESUMO
OBJECTIVE: To determine the oncological outcomes of salvage transoral laser microsurgery (TLM) in the treatment of patients suffering from recurrent laryngeal cancer. METHODS: PubMed/MEDLINE, Cochrane Library, and Scopus databases were searched. English language, original studies investigating oncological outcomes of TLM in adult patients with recurrent laryngeal cancer were included. Data were pooled using a distribution-free approach for estimating summary local control (LC), disease-specific survival (DSS), and overall survival (OS) curves with random effects. RESULTS: Two hundred and thirty-five patients underwent salvage TLM after primary (chemo)radiotherapy. The mean follow-up time was 60.8 months (95% CI: 32.7-88.9). Estimated pooled LC rates (95% CI) at 1, 3 and 5 years were 74.2% (61.7-89.4), 53.9% (38.5-75.3), and 39.1% (25.2-60.8). Estimated pooled DSS rates (95% CI) at 1, 3 and 5 years were 88.4% (82.0-95.3), 67.8% (50.9-90.3), and 58.9% (42.7-81.1). Two hundred and seventy-one patients underwent TLM after primary laser treatment. The mean follow-up time was 70.9 months (95% CI: 36.9-104.9). Estimated pooled LC rates (95% CI) at 1, 3 and 5 years were 72.2% (64.7-80.6), 53.2% (42.2-66.9), and 40.4% (29.6-55.2). Estimated pooled DSS rates (95% CI) at 1, 3 and 5 years were 92.1% (85.5-99.1), 77.0% (64.4-92.0), and 67.1% (51.6-87.3). CONCLUSIONS: TLM is a valuable treatment option for the management of locally recurrent laryngeal carcinoma if performed by experienced surgeons and following rigorous patients' selection criteria. Further studies should be conducted to define stage-based clinical guidelines. LEVEL OF EVIDENCE: NA Laryngoscope, 133:1425-1433, 2023.

BACKGROUND: For recurrent laryngeal cancer, the feasibility of salvage transoral laser microsurgery (TLM) remains controversial. This study compared the efficacy of TLM and open partial laryngectomy (OPL) for treatment of early local recurrence of glottic squamous cell cancer (GSCC) and confirm the effectiveness of salvage TLM as a treatment option. METHODS: This retrospective study involved 55 patients with early local recurrent GSCC treated with TLM, and the oncologic outcomes, functional outcomes, hospitalization time and complications were compared with a group of 40 recurrent GSCC patients matched for clinical variables of TLM group, treated by OPL by the same team of surgeons. RESULTS: The 5-year overall survival and disease-specific survival rates were 65.8% and 91.5%, respectively, for 55 patients with rTis-rT2 stage treated by TLM and 77.1% and 94.7%, respectively, for 40 patients with rTis-rT2 stage treated by OPL (OPL group). In the TLM and OPL groups, the local control rates after 5 years were 77.5% and 79.3%, respectively, and the laryngeal preservation rates were 94.4% and 83.6%, respectively (p > 0.05). Compared with the OPL group, the complication rate (1.82%) and hospitalization duration (5.42 ± 2.26 days) were significantly lower in the TLM group (p < 0.05). Compared with the OPL group, postsurgical health-related quality of life and quality of voice were significantly better in the TLM group (p < 0.001). CONCLUSION: Salvage TLM can be used as an effective treatment option for suitable patients after a full, comprehensive, and careful assessment of the characteristics of early locally recurrent glottic carcinoma.

The incidence of all head and neck malignancies is rising worldwide, with carcinoma of the larynx constituting approximately 1% of all cancers. Early glottic cancer responds quite favorably to surgical intervention due to its early presentation, coupled with the low rate of regional and distant metastases. This article focuses on various approaches to the surgical treatment of early glottic cancer. Details include the clinical and radiological evaluation of laryngeal cancer, the goals of treatment, current surgical options for early disease, approach to surgical resection margins and management of nodal disease, and complications associated with each treatment modality.

Objective: Laryngeal chondritis (LC) is a rare complication of carbon dioxide transoral laser microsurgery (CO2 TOLMS) for laryngeal tumours and can pose a diagnostic challenge. Its magnetic resonance (MR) features have not been previously described. This study aims to characterise a cohort of patients who developed LC after CO2 TOLMS and describe its clinical and MR findings. Methods: Clinical records and MR images of all patients presenting with LC after CO2 TOLMS between 2008 and 2022 were reviewed. Results: Seven patients were analysed. Timing of LC diagnosis ranged from 1 to 8 months after CO2 TOLMS. Four patients were symptomatic. Abnormal endoscopic findings included suspected tumour recurrence in 4 patients. MR documented focal or extensive signal changes involving the thyroid lamina and para-laryngeal space with T2 hyperintensity, T1 hypointensity and intense contrast enhancement (n = 7), and minimally reduced mean apparent diffusion coefficient (ADC) values (1.0-1.5 x 10-3 mm2/s) (n = 6). A favourable clinical outcome was achieved in all patients. Conclusions: LC after CO2 TOLMS has a distinctive MR pattern. When tumour recurrence cannot be confidently excluded based on imaging, antibiotic therapy, close clinical and radiological follow-up and/or biopsy are recommended.

OBJECTIVES: This study presents an efficient, safe, effective, and novel technique of reconstructive transoral laser microsurgery (R-TLM) for the treatment of unilateral vocal fold paralysis (UVFP) with airway obstruction. It is based on the augmentation of the immobile and potentially flaccid and atrophic side while lateralizing the arytenoid and posterior part of the vocal fold, thus improving breathing without sacrificing phonation and commonly improving it. STUDY DESIGN: Retrospective cohort study through data from medical records and operative notes. METHODS: Patients with UVFP with exertional dyspnea with or without dysphonia were included in this report. The vocal fold is augmented by harvesting the aryepiglottic fold soft tissues and the upper part of the arytenoid and placing them into the paraglottic space as a pedicled microflap, thus augmenting the anterior two thirds of the vocal fold while lateralizing the remaining arytenoid and posterior third of the vocal fold by an internal traction suture to improve airway. Postoperative breathing, phonation and swallowing were assessed. RESULTS: Twenty two cases are reported in the study. Follow-up evaluations ranged from 6 to 12 months. All cases showed successful and durable improvement of breathing and phonation. None required tracheostomy or gastrostomy pre- or postoperatively. CONCLUSIONS: Augmentation-lateralization is a novel, safe, and effective minimally invasive technique that allows airway improvement with good results on phonation in patients with challenging UVFP with airway obstruction.
RESUMO
Objective: To determine the 5-year survival outcomes of patients with oropharyngeal cancer treated with transoral laser microsurgery at our institution. Methods: A prospective longitudinal cohort study of all cases of oropharyngeal squamous cell cancer or clinically unknown primaries diagnosed at our institution between September 1, 2014, to December 31, 2019, treated with primary transoral laser microsurgery were analyzed. Patients with a previous history of head and neck radiation were excluded from analysis. Kaplan-Meier survival curves were used to estimate 5-year overall survival, disease-specific survival, local control, and recurrence free survival rates in oropharyngeal squamous cell carcinoma. Results: Of 142 patients identified, 135 met criteria and were included in the survival analysis. Five-year local control rates in p16 positive and negative disease were 99.2% and 100%, respectively, with one locoregional failure in the p16 positive cohort. Five-year overall survival, disease-specific survival, and recurrence free survival in p16 positive disease were 91%, 95.2%, and 87% respectively (n = 124). Five-year overall survival, disease-specific survival, and recurrence free survival in p16 negative disease were 39.8%, 58.3%, and 60%, respectively (n = 11). The permanent gastrostomy tube rate was 1.5% and zero patients received a tracheostomy at the time of surgery. One patient (0.74%) required a return to the OR for a post-operative pharyngeal bleed. Conclusion: Transoral laser microsurgery is a safe primary treatment option for oropharyngeal squamous cell carcinoma with high 5-year survival outcomes, notably in p16 positive disease. More randomized trials are needed to compare survival outcomes and associated morbidity in transoral laser microsurgery compared to treatment with primary chemoradiation. Level of Evidence: 3.

OBJECTIVES: To evaluate the safety and clinical effectiveness of transoral laser microsurgery (TLM) with potassium-titanyl-phosphate (KTP) laser ablation for glottic neoplasms. DATA SOURCE: MEDLINE via PubMed, SCOPUS, Web of Science, and Cochrane Library. REVIEW METHODS: A systematic review and meta-analysis of studies assessing the safety and efficacy of KTP laser therapy in patients with early-stage glottic neoplasms. RESULTS: Eight studies were included. After an average follow-up of 3.3 years, the overall survival and disease-free survival for patients who underwent KTP were 90.7% (95% CI 85%-96.5%) and 98.5% (95% CI 97.3%-99.8%), respectively. In the single-arm meta-analysis, the pooled estimate of recurrence was 7.7% (95% CI 3.4%-12%). The overall voice handicap index (VHI) estimate attributed to KTP in the single-arm meta-analysis was 6.76 (95% CI [3.05, 10.48]) and 5.21 (95% CI [2.86, 7.56]) within 6 months and after a one-year follow-up, respectively. CONCLUSION: KTP laser ablation is a safe and effective method for treating patients with early glottic neoplasms. Laryngoscope, 133:1806-1814, 2023.

OBJECTIVES: This study aims to demonstrate the benefit of reconstructive transoral laser microsurgery (R-TLM) in decannulation of tracheostomy-dependent patients with airway obstruction. METHODS: A consecutive series of tracheostomy-dependent patients who underwent R-TLM using multiple techniques described in our previous works, were reviewed for outcomes especially for decannulation. Full airway examination was essential to determine the anatomical and functional sites of obstruction to establish the surgical plan including R-TLM techniques needed to improve airway prior to permanent decannulation. RESULTS: Twenty-two patients were treated. Eighteen subjects were successfully decannulated. Single or multiple R-TLM surgical technique(s) was/were performed during the same surgery to treat upper airway stenosis at the level of the hypopharynx, larynx, and trachea. The mean number of surgeries per patient was 2.1. Patients were followed up for at least 12 months. CONCLUSION: R-TLM combines different surgical techniques which can be used individually or combined in a stepwise surgical plan for permanent decannulation of tracheostomy-dependent patients with a previous history of decannulation failure secondary to airway obstruction. Accurate preoperative examination gives valuable information about airway and allows establishing a stepwise surgical plan that may need multiple surgeries for full permanent decannulation of these patients.
