ObjectiveThe 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.Methods103 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.ResultsOf 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.ConclusionThe 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.Level of Evidence2 Laryngoscope, 2023

“…Good laryngeal exposure is an essential consideration in previously irradiated patients and can be compromised because of reduced neck flexibility and tissue elasticity. The Laryngoscore and the mini-Laryngoscore are preoperative tools aimed at predicting laryngeal exposure by analyzing patient characteristics [36][37][38][39]. The Laryngoscore includes previous (C)RT as a negative factor for intraoperative exposure, and its influence should be considered together with other anatomical variables.…”

Purpose To provide expert opinion and consensus on salvage carbon dioxide transoral laser microsurgery (CO2 TOLMS) for recurrent laryngeal squamous cell carcinoma (LSCC) after (chemo)radiotherapy [(C)RT]. Methods Expert members of the European Laryngological Society (ELS) Cancer and Dysplasia Committee were selected to create a dedicated panel on salvage CO2 TOLMS for LSCC. A series of statements regarding the critical aspects of decision-making were drafted, circulated, and modified or excluded in accordance with the Delphi process. Results The expert panel reached full consensus on 19 statements through a total of three sequential evaluation rounds. These statements were focused on different aspects of salvage CO2 TOLMS, with particular attention on preoperative diagnostic work-up, treatment indications, postoperative management, complications, functional outcomes, and follow-up. Conclusion Management of recurrent LSCC after (C)RT is challenging and is based on the need to find a balance between oncologic and functional outcomes. Salvage CO2 TOLMS is a minimally invasive approach that can be applied to selected patients with strict and careful indications. Herein, a series of statements based on an ELS expert consensus aimed at guiding the main aspects of CO2 TOLMS for LSCC in the salvage setting is presented.
