RESUMO
OBJECTIVE: To explore the differences between clinical features and computed tomography (CT) findings of early-stage glottic cancer (EGC) with or without recurrence after transoral laser microsurgery (TLM) and to establish a preoperative nomogram to predict postoperative recurrence. METHODS: The clinical and CT features of 168 consecutive patients with EGC with or without recurrence were analyzed retrospectively. Multivariate logistic regression analysis was used to determine the independent predictors of recurrence. A nomogram was constructed to preoperatively predict recurrence. To assess the nomogram's performance, the C-index and calibration plot were used. RESULTS: EGCs with and without recurrence differed significantly in T-stage, depth, and normalized CT values in the arterial phase (NCTAP) and venous phase (NCTVP) (all P < 0.05). T-stage, depth, and NCTVP were independent predictors of recurrence in EGCs (all P < 0.05). The C-index (0.765, 95% confidence interval: 0.703-0.827) and calibration plot showed that the nomogram has good prediction accuracy. Nomograms based on T-stage and CT variables provided numerically predicted recurrence rates and were better than those based on only T-stage (C-index of 0.765 vs. 0.608). CONCLUSIONS: Using clinical and CT variables, we developed a novel nomogram to predict the recurrence of EGC before TLM, which may be a potential noninvasive tool for guiding personalized treatment.

OBJECTIVE: Frozen biopsy may guide surgical intraoperative decisions. We evaluated the accuracy of frozen biopsy for diagnosing benign, dysplastic and malignant laryngeal lesions, compared to paraffin section (gold standard). METHODS: Retrospective review of the charts of all patients presenting with laryngeal lesions suspicious of malignancy, who underwent laryngeal microsurgery with frozen biopsy in our institution, between 2015 and 2020. Results of frozen biopsy and paraffin section examinations were compared. RESULTS: Among 113 samples of 89 patients, paraffin section diagnosed 23 benign, 31 dysplastic and 59 malignant lesions. The accuracy of the frozen biopsy in identifying dysplasia or malignancy was 80.5% (91/113), and greater for lesions >5â¯mm (78.8%â¯×â¯51.5%; pâ¯=â¯0.009). The positive and negative predictive values, sensitivity and specificity were 95.9%, 51.3%, 78.9% and 86.9%, respectively. CONCLUSIONS: Frozen section is a reliable tool when malignancy is detected, but almost half of benign results exhibit dysplasia or malignancy in paraffin section. Other clinical parameters should be considered in intraoperative decisions to prevent undertreatment.

OBJECTIVES: Transoral laser microsurgery (TLMS) and radiotherapy (XRT) are mainstays of treatment for early glottic carcinoma (EGC). Here, we investigated case-dependent provider treatment preferences and identify factors which impact decision-making in EGC. METHODS: This cross-sectional survey of laryngologists, head-and-neck surgeons, and radiation oncologists presented five diagrammatic cases of progressively advanced EGC (T1/2, N0). Respondents indicated preference for TLMS or XRT and ranked factors which influenced their recommendation for each case. Analysis utilized descriptive statistics, Fischer's exact tests, and Kruskal-Wallis tests for nonparametric data. RESULTS: A total of 141 complete responses (69.5% laryngologists) were received. Most respondents practiced in academic settings (93.5%) and within multidisciplinary teams (94.0%). Anterior commissure involvement was the most important a priori tumor factor for case-independent treatment recommendation (Likert Scale: 4.22/5), followed by Laterality (Likert Scale: 4.02/5). Across all specialties, TLMS was recommended for unilateral T1a lesions. Laryngologists continued recommending TLMS in T2 lesions (41.0%) more than head-and-neck surgeons (5.0%) and radiation oncologists (0.0%). Across all cases, survival and voice outcomes were the most important clinical factors impacting treatment decisions. Radiation oncologists weighed voice more heavily than laryngologists in more complex presentations of EGC (rank: 1.6 vs. 2.7, Kruskall-Wallis: p < 0.05). CONCLUSIONS: In more complex clinical presentations of EGC, preference for TLMS compared to XRT differed across specialists, despite similar rankings of factors driving these treatment recommendations. This may be driven by differing experiences and viewpoints on case-dependent voice outcomes following TLMS versus XRT, suggesting a need for increased understanding of how tumor location and depth impact voice outcomes.

OBJECTIVES: To assess the value of carbon dioxide transoral laser microsurgery (CO2 TOLMS) for early-stage glottic cancer with special regard to involvement of the anterior commissure (AC). STUDY DESIGN: Single-center retrospective cohort study. SETTING: Grade-A tertiary hospital. METHODS: A retrospective analysis of patients with early-stage (Tis-T2) glottic cancer who underwent CO2 TOLMS. All patients had at least 2 years of follow-up. The univariate and multivariate survival analyses were used to identify the risk factors for recurrence and the Kaplan-Meier method was used to analyze OS and DSS rates. RESULTS: A total of 102 patients were included in the study. Eleven patients (10.78%) had recurrence. The univariate analysis showed that the recurrence was associated with the AC classification, T staging, tumor size, and tobacco use (P < .05). However, on multivariate analysis, the AC classification was the only independent risk factor for recurrence (P < .001, HR = 3.179). AC classification were distributed as follows: 59 (57.84%) AC0, 29 (28.43%) AC1, 8 (7.84%) AC2, and 6 (5.88%) AC3, 2-year/5-year OS and DSS rates were progressively reduced in the AC0, AC1, AC2, and AC3 groups (P < .001). At the same T staging, the OS rates incrementally decreased as the level of involvement of the AC became higher (P = .004). CONCLUSION: CO2 TOLMS is an effective treatment for early-stage glottic cancer. AC involvement is an independent risk factors for recurrence and poor prognosis. The AC classification system may be better at grading the prognosis of patients with early-stage glottic cancer and has prognostic value independent of T staging.

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.

OBJECTIVE: Numerous methods and materials are available for vertical partial laryngectomy. In this study, the reparative effects of the platysma myocutaneous flap (PMF) and ribbon myocutaneous flap (RMF) on the postoperative voice quality of patients were compared to provide a reference for selecting a method conducive to improving postoperative voice quality. METHODS: A retrospective analysis was performed on patients with unilateral T2-3 glottic carcinoma. Following vertical partial laryngectomy, the defect was repaired with a PMF or simple RMF. Twelve months after surgery, voice quality was assessed according to voice acoustics, aerodynamics, and subjective perceptual evaluation, and glottic morphology was recorded using a laryngeal stroboscopy. RESULTS: A total of 70 patients were identified, including 54 in the PMF group and 16 in the RMF group. The PMF group was superior to the RMF group in terms of voice quality assessed by voice acoustics, aerodynamics, and subjective perceptual evaluation. In the PMF group, 72.2% of patients performed phonation with their vocal cords, and approximately 27.8% of patients were affected by supraglottic compression. In the RMF group, 81.3% of patients were affected by supraglottic compression. No significant difference was found in the 5-year survival rate between the two groups. CONCLUSION: For defect repair following vertical partial laryngectomy, a PMF can allow better postoperative voice quality to be achieved than an RMF because a PMF can provide more tissue (including strap muscle under the flap) for padding, which enables the glottic portion corresponding to the vocal cord to close well.

INTRODUCTION: Many transsexual women seek to feminise their voice through pitch elevation surgeries so that it becomes congruent with their gender identity. This study aims to determine the safety and effectiveness of Wendler glottoplasty (WG) in vocal feminisation through the assessment of acoustic and aerodynamic parameters of the voice, as well as voice-related quality of life (QoL) in male-to-female transsexuals. MATERIAL AND METHODS: We retrospectively reviewed the medical records of transsexual women who underwent WG for voice feminisation at our institution between 2016 and 2023. All acoustic and aerodynamic analyses, a voice self-assessment, and a videolaryngostroboscopic evaluation were performed in the immediate preoperative period and at the follow-up visit 6 weeks after the procedure. RESULTS: A total of 11 patients with a mean age of 32.73 years were included. After WG, there was a significant fundamental frequency and speaking fundamental frequency increase of 109.64 Hz and 83.48 Hz, respectively (p < 0.001), representing an average rise by 9.71 semitones and 8.36 semitones (STs), respectively. No significant differences were found between the mean pre- and postoperative values of fundamental frequencies, frequency range, upper limit of the frequency range of spoken voice, and maximum phonation time. Contrarily, the mean lower limit of frequency range rose by 75.56 Hz (p < 0.001), representing an average increase of 10.56 STs. None of the assessed spirometric parameters changed significantly after WG (p > 0.05). The mean overall Voice Handicap Index (VHI) and Voice-Related Quality of Life (V-RQOL) scores significantly improved after the surgery, decreasing by 24.54 points (p = 0.008) and 11.5 points (p = 0.001), respectively. A significant improvement was observed in the functional and emotional domains of VHI. Additionally, significantly fewer patients considered the overall quality of their voice to be "poor" after WG. CONCLUSIONS: WG constitutes an effective method of surgical voice feminisation in male-to-female transsexuals with concurrent improvement in their voice-related QoL. Furthermore, it remains a safe procedure without persistent complications and negative influence on the acoustic-aerodynamic measures of the voice.

PURPOSE: To identify a radiological map of laryngeal subsites whose involvement by the tumor could predict patients' functional outcomes after open partial horizontal laryngectomy (OPHL). METHODS: The present retrospective analysis concerned 96 patients with glottic squamous cell carcinoma, who were radiologically staged with contrast-enhanced neck CT scans before undergoing supracricoid or supratracheal laryngectomy. A radiological map of patients' functional risk was developed by considering the distribution of functional outcomes in relation to the laryngeal subsites involved. The functional outcomes considered were: (i) decannulation at discharge; (ii) time to removal of the nasogastric feeding tube (NFT); (iii) postoperative complication rate; and (iv) length of hospital stay. RESULTS: Involvement of the anterior supraglottis was related to a longer need for NFT, and a longer hospital stay (p = 0.003, and p = 0.003, respectively). Involvement of the posterior glottis negatively affected the time to decannulation, and the likelihood of postoperative complications (p = 0.000, and p = 0.002, respectively). CONCLUSIONS: Anterior glottic small tumors (without significant subglottic and/or supraglottic extension) are related to the best functional outcomes after OPHL, since the suprahyoid epiglottis and both the arytenoids are likely to be spared.

Objective: Laryngeal cancer is a common tumor in the head and neck, and surgery is one of the main treatment methods for laryngeal cancer. Laryngeal cancer surgery destroys the laryngeal cartilage scaffold, leading to structural changes in the laryngeal cavity and affecting respiratory compliance during sleep. However, less attention has been paid to the impact of changes in laryngeal structure on sleep breathing conditions. This article conducts a prospective study on the effects of preserving laryngeal function in cancer glottic surgery on sleep and respiratory status in patients, in order to understand the preoperative and postoperative OSAHS(obstructive sleep apnea-hypopnea syndrome) of glottic cancer patients , as well as the impact of surgery on OSAHS of patients. Provide a reference for improving the sleep quality of postoperative patients with laryngeal cancer. Methods: 47 patients with glottic cancer who underwent laryngeal function preservation surgeries were studied. They are divided into 28 cases of T1 and T2, who underwent vertical lateral frontal partial laryngectomy (VLFPL), and 19 cases of T3 and T4 who underwent vertical lateral frontal subtotal laryngectomy (VLFSL). All patients' sleep breathing statuses were recorded using a portable sleep breathing monitor one week before surgery and two months after the removal of the tracheal cannula. Analyze the proportion of OSAHS in the 47 patients before and after surgery and compare the obstructive sleep apnea scores of these patients using the Wilcoxon rank sum test of paired grade data. The paired data t-test was used to analyze the apnea-hypopnea index (AHI), apnea index (AI), hypopnea index (HI), minimum blood oxygen saturation (LSaO2), and mean blood oxygen saturation (MSaO2) of all study subjects, patients undergoing VLFPL and VLFSL. Results: 1. Among the 47 patients with glottic cancer, 42.6% (20 / 47) were in line with OSAHS before the operation, and 57.4% (27 / 47) were in line with OSAHS after the operation. 47 patients showed an increasing trend in the OSAHS scores (no, mild, moderate, and severe) after surgery compared to the before-surgery scores, and the difference was statistically significant (P < 0.05). 2. Among the 47 study subjects, AHI and HI increased after surgery compared to preoperative, while LSaO2 and MSaO2 decreased after surgery compared to preoperative (P < .05); There was no statistically significant difference between postoperative and preoperative AI (P > .05). Among 28 patients undergoing VLFPL, LSaO2 decreased after surgery compared to before surgery (P < .05) and there was no statistically significant difference in AHI, AI, MSaO2, and HI after surgery compared to before surgery (P > .05). Among 19 patients undergoing VLFSL, AHI, and HI increased after surgery, while LSaO2 and MSaO2 decreased after surgery (P < .05) and there was no statistically significant difference in postoperative AI compared to preoperative (P > .05). Conclusion: The prevalence of OSAHS in patients with glottic cancer before and after surgery was higher than that in the general population. The effect of functional preservation surgery on sleep breathing in patients with glottic cancer is related to the degree of destruction of the thyroid cartilage scaffold and the scope of surgery. Surgery mainly increases the degree of OSAHS by aggravating patients' hypoventilation rather than apnea.

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: This study aimed to investigate the impact of the implant's vertical location during Type 1 Thyroplasty (T1T) on acoustics and glottal aerodynamics using excised canine larynx model, providing insights into the optimal technique for treating unilateral vocal fold paralysis (UVFP). METHODS: Measurements were conducted in six excised canine larynges using Silastic implants. Two implant locations, glottal and infraglottal, were tested for each larynx at low and high subglottal pressure levels. Acoustic and intraglottal flow velocity field measurements were taken to assess vocal efficiency (VE), cepstral peak prominence (CPP), and the development of intraglottal vortices. RESULTS: The results indicated that the implant's vertical location significantly influenced vocal efficiency (p = 0.045), with the infraglottal implant generally yielding higher VE values. The effect on CPP was not statistically significant (p = 0.234). Intraglottal velocity field measurements demonstrated larger glottal divergence angles and stronger vortices with the infraglottal implant. CONCLUSION: The findings suggest that medializing the paralyzed fold at the infraglottal level rather than the glottal level can lead to improved vocal efficiency. The observed larger divergence angles and stronger intraglottal vortices with infraglottal medialization may enhance voice outcomes in UVFP patients. These findings have important implications for optimizing T1T procedures and improving voice quality in individuals with UVFP. Further research is warranted to validate these results in clinical settings.

OBJECTIVE: The prognostic value of depth of invasion (DOI) in oral squamous cell cancer carcinoma and cutaneous melanoma is well established, while there is a lack of reports investigating the role of DOI in laryngeal cancer. This study aims to explore the association of glottic cancer DOI with other established pathological risk factors and nodal metastasis and evaluate the feasibility of measuring DOI preoperatively using tomographic imaging. METHODS: The medical records of glottic cancer patients treated between 2015 and 2020 in a single tertiary referral center were screened retrospectively. Pathologically measured DOI (pDOI) value was also reviewed and registered. Preoperative computer tomography (CT) was used to obtain the radiological DOI (rDOI) measured by two dedicated radiologists. Their inter-rated agreement was assessed and the correlation between pDOI and rDOI was calculated. pDOI association with the main pathology report features was assessed with univariable analysis. Cox univariable and multivariable models were used to explore the role of pDOI on survival. RESULTS: Ninety-one patients had pDOI data available, of which 59 also had rDOI data. A strong concordance between the two radiologists was found (concordance correlation coefficient = 0.96); rDOI and pDOI were highly and significantly correlated (R = 0.85; p < 0.001). pDOI was significantly higher in patients with perineural invasion (PNI; p < 0.001), lymphovascular invasion (LVI; p < 0.001), and nodal metastasis (p < 0.001). pDOI was associated with disease-free survival at univariable analysis (p = 0.04) while it did not show a significant impact (p = 0.10) at multivariable analysis. CONCLUSION: Glottic carcinoma DOI correlates with PNI, LVI, and nodal metastasis and it can be reliably assessed in a preoperative setting using CT imaging.

OBJECTIVE(S): Describe recent national trends in overall treatment modalities for T1 glottic squamous cell carcinomas (SCC), and identify factors associated with treatment regimens. METHODS: National Cancer Database from 2004-2020 was queried for all patients with glottic cT1N0M0 SCC. Treatment patterns over time were analyzed using the Cochran-Armitage test for trend. Multivariable logistic regressions were used to determine the factors associated with treatment regimens. RESULTS: Of the 22,414 patients identified, most patients received RT only (57%), 21% received surgery only, and 22% received dual-modality treatment ("over-treatment"). Over the time period, there was a decreasing trend in rates of over-treatment for T1 glottic SCC (p < 0.001) and an increasing trend in surgery only (p < 0.001). Treatment in 2016-2018 (OR: 1.168 [1.004 to 1.359]), 2013-2015 (OR: 1.419 [1.221 to 1.648]), 2010-2012 (OR: 1.611 [1.388 to 1.871]), 2007-2009 (OR: 1.682 [1.450 to 1.951]), or 2004-2006 (OR: 1.795 [1.548 to 2.081]) versus 2019-2020 was associated with greater likelihood of over-treatment. T1b tumors were less likely to be over-treated (OR: 0.795 [0.707 to 0.894]) versus T1a tumors, and less likely to receive surgery first (OR: 0.536 [0.485 to 0.592]) versus T1a tumors. CONCLUSION: Over-treatment for T1 glottic SCC has been declining, with increasing rates of surgery only. Year of treatment was significantly associated with the receipt of dual-modality treatment. Finally, patients with T1b disease were more likely to receive RT as the first and only treatment. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:3633-3644, 2024.

PURPOSE: Since new evidence regarding the impact of Wendler glottoplasty (WG) on the voice in transgender women became available in the literature in recent years, we aimed to perform an updated systematic review and meta-analysis to determine the actual safety and efficacy of WG in the process of vocal feminization. METHODS: PubMed, Embase, and Cochrane were searched for English-language articles published until July 4, 2023. Studies were found eligible if they evaluated the impact of WG on the acoustic-aerodynamic measures and quality of voice in transgender women. RESULTS: Twenty-three studies were identified. After exclusion of three studies due to incomplete data, 20 studies including 656 patients were included in the meta-analysis. After WG, there was a significant increase of fundamental frequency, speaking fundamental frequency, and lower limit of the frequency range (p < 0.001). Concurrently, a significant reduction of frequency range and maximum phonation time was observed (p < 0.001). No significant differences were found between the pre- and postoperative values regarding the Grade, Roughness, Breathiness, Asthenia, and Strain scale score (p = 0.339). The overall score in the Trans Woman Voice Questionnaire (TWVQ) significantly improved after WG (p < 0.001). CONCLUSIONS: WG is an effective voice feminization method in transgender women, associated with a high procedural success and low risk of postoperative complications. Significantly improved TWVQ score after surgery suggests its positive impact on the voice-related quality of life. Postoperative decrease of maximum phonation time and frequency range does not seem to significantly impact the effectiveness of voice production.

BACKGROUND: Early glottic cancer can be treated with laser resection or radiotherapy. In an earlier study, we found that voice function after laser resection was inferior to that after radiotherapy. OBJECTIVES: This study was designed to determine if reduced margins at laser resection improved voice function without impairing oncologic results. METHOD: A total of 268 patients with previously untreated T1-T2 glottic carcinoma were studied. They were primarily treated with either radiotherapy (n = 119) or laser resection (n = 149). Survival, need for additional treatment (radiotherapy and/or total layngectomi) and voice function was compared. RESULT: Median follow up time was 7 years with range 0.5-16.6. There was no difference in the overall survival (p = .065) or disease-specific survival. (p = .126). After radiotherapy 32/119 patients and after laser resection 57/149 patients had recurrence. Total rate of laryngectomy was 24% in the radiotherapy group, and 8% in the laser resection group (p = .001). Voice analysis (T1A) showed more roughness in the radiotherapy group, otherwise no difference. CONCLUSIONS: By reducing the surgical margins, we have achieved a better voice function (T1A) but more patients have needed repeated laser excisions and some have also needed supplementary radiotherapy. The risk of laryngectomy and survival were apparently not affected.

OBJECTIVE: Age-related vocal atrophy (ARVA) is associated with vocal fold bowing, persistent glottal gap during phonation, and dysphonia. Bilateral medialization thyroplasty is sometimes performed in patients with ARVA to improve vocal fold closure and voice. We set out to quantify stroboscopic changes in vocal fold bowing, glottal closure, and abduction angle following bilateral thyroplasty and determine how these changes affect voice quality among patients with ARVA. METHODS: Fifteen individuals with ARVA who underwent bilateral medialization thyroplasty were included in this study. Two independent investigators calculated bowing index (BI), normalized glottal gap area (NGGA), and maximum abduction angle from laryngostroboscopic exams using ImageJ™. Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) and patient-reported measures were collected before and after thyroplasty. RESULTS: Thyroplasty resulted in a 10-point improvement in overall CAPE-V (Mean dif -10; 95% CI -17, -3.3, p < 0.01) and VHI-10 (mean dif -3.8; 95% CI -9.8, 2.3, p = 0.19, n = 8). NGGA and BI significantly decreased following surgery (mean dif -78; 95% CI -155, -1.5, p = 0.05; and mean dif -2.1; 95% CI -2.4, -0.84, p < 0.01, respectively). BI correlated with CAPE-V scores (r = 0.66, 95% CI 0.22, 0.87, p < 0.01). When considering the normalized combined contributions of both NGGA and BI, there was a stronger correlation in CAPE-V scores (r = 0.87, 95% CI 0.50, 0.97, p < 0.01) compared with either measure alone. CONCLUSIONS: Thyroplasty resulted in a decrease in vocal fold bowing, glottal gap area, and CAPE-V scores in patients with ARVA. Correction of vocal bowing and glottal gap, following bilateral thyroplasty, improved voice measures following surgery. Quantitative evaluation of vocal fold morphology may be valuable when assessing the severity and treatment-response in patients with ARVA following bilateral thyroplasty.

OBJECTIVE: Early-stage glottic cancer (ESGC) is a malignancy of the head and neck. Besides disease control, preservation and improvement of voice quality are essential. To enable expectation management and well-informed decision-making, patients should be sufficiently counseled with individualized information on expected voice quality. This study aims to develop an individualized dynamic prediction model for patient-reported voice quality. This model should be able to provide individualized predictions at every time point from intake to the end of follow-up. STUDY DESIGN: Longitudinal cohort study. SETTING: Tertiary cancer center. METHODS: Patients treated for ESGC were included in this study (N = 294). The Voice Handicap Index was obtained prospectively. The framework of mixed and joint models was used. The prognostic factors used are treatment, age, gender, comorbidity, performance score, smoking, T-stage, and involvement of the anterior commissure. The overall performance of these models was assessed during an internal cross-validation procedure and presentation of absolute errors using box plots. RESULTS: The mean age in this cohort was 67 years and 81.3% are male. Patients were treated with transoral CO2 laser microsurgery (57.8%), single vocal cord irradiation up to (24.5), or local radiotherapy (17.5%). The mean follow-up was 43.4 months (SD 21.5). Including more measurements during prediction improves predictive performance. Including more clinical and demographic variables did not provide better predictions. Little differences in predictive performance between models were found. CONCLUSION: We developed a dynamic individualized prediction model for patient-reported voice quality. This model has the potential to empower patients and professionals in making well-informed decisions and enables tailor-made counseling.

Laryngomalacia is the most frequent congenital laryngeal anomaly. Surgery is possible by means of cold knife, carbon dioxide (CO2 ) laser, microdebrider and coblation, traditionally under microscopic view. We here describe the use of the 3D-4K exoscope assisted CO2 laser supraglottoplasty in tubeless general anesthesia in spontaneous breathing in a 5 month-old patient with severe laryngomalacia. Laryngoscope, 134:1359-1362, 2024.

PURPOSE: There is no agreement on the most appropriate post-operative pathway for the management of positive margins after laser cordectomy for early stage glottic tumours (T1-2N0M0). This literature review and meta-analysis aim to evaluate the post-operative treatment with the best oncological results among follow-up, radiotherapy (RT) and surgical second look. The parameters utilized were incidence of recurrence, overall (OS), disease-specific (DSS) and disease-free (DFS) survival and larynx preservation (LP). METHODS: The articles were found through a string typed into PubMed from 2007 to 2022. The studies with detailed oncological results were selected according to inclusion criteria, and then the meta-analysis was carried out. RESULTS: Sixteen studies met the inclusion criteria for 2808 patients. The positive margin was found in 748 patients (26.6%), of which 416 were referred to follow-up, 89 to RT and 242 to a surgical second look. A false positive margin was found in 58/104 patients (56%). The recurrence rate in patients with positive margins was significantly higher (p = 0.003). In OS, DSS, DFS and LP, the odds ratio (OR) value was always greater than 1, assessing the role of the positive margin as a risk factor. CONCLUSIONS: Prospective studies will be necessary to establish the role of positive margin as a prognostic factor. A surgical second look in case of positive margin seems to be the best option for the patient in terms of lower risk of recurrence and better oncological results. Better collaboration between surgeon and pathologist would be desirable to limit the real and false positive margins.
