Objectives Optimal laryngeal exposure during transoral laryngeal surgery is fundamental. We aimed to evaluate the reliability of a recently proposed score (Laryngoscore) in predicting difficult laryngeal exposure (DLE) in an independent cohort of patients undergoing elective microlaryngoscopy. We also verified the relation between DLE, surgeon's expertise, and difficult intubation, and investigated possible areas for score improvement. Study Design Prospective validation study. Methods A total of 136 patients were preoperatively evaluated using the Laryngoscore. Patients were divided into three classes according to patient position, type of laryngoscope, and need for external counterpressure to expose the anterior commissure. Based on their mean scores, two groups were identified: good laryngeal exposure (GLE) and DLE. A receiver operating characteristic curve with the Youden index was used to calculate the optimal cutoff value. The χ2 and Fisher exact test were used to correlate GLE and DLE to the surgeon's expertise and difficult intubation. The intraoperative anatomical parameters underlying DLE were also recorded. Results The optimal cutoff value for differentiating GLE and DLE was 4, which identified 80.6% of DLE cases. No statistically significant difference in GLE and DLE distribution was found between surgeons (P = 0.43). The correlation between difficult intubation and DLE was statistically significant (P = 0.03). The intraoperative parameters determining DLE were epiglottis characteristics (floppy, tight, or short), bulky abdomen and chest, bulky tongue base, mobile teeth, and a narrow laryngeal aditus. Conclusion The Laryngoscore is reliable for detecting DLE preoperatively. The inclusion of additional parameters may allow a more complete assessment and maximize its diagnostic accuracy.

Objective Recently, a novel host‐related index, the Host‐index (H‐index), including both inflammatory and nutritional markers, has been described and observed to stratify prognosis in patients with squamous cell carcinoma (SCC) of the oral cavity more accurately than other host‐related indexes This study aimed to investigate the prognostic performance of the H‐index using pretreatment blood tests in patients receiving up‐front surgery for SCC of the larynx. Methods This retrospective observational study included a multicenter series of consecutive patients with SCC of the larynx diagnosed between 1 January 2009 and 31 July 2018, whose pretreatment blood tests were available and included the parameters necessary for the calculation of neutrophil to lymphocyte ratio (NLR) and the H‐index. Their association with disease‐free survival (DFS) and overall survival (OS) was measured. Results A total of 231 patients were eligible for the present analysis (median [range] age, 68 [37‐96] years; 191 [82.7%] men). The median follow‐up was 73 months. In multivariable Cox proportional hazards regression models, increasing age (adjusted hazard ratio [aHR], 1.07 per year; 95% CI, 1.04‐1.09), advanced pT stage (aHR = 1.71 95% CI: 1.07‐2.71), and having close or positive surgical margins (aHR = 2.01; 95% CI: 1.21‐3.33) were significantly associated with poor OS. Among blood parameters, a higher neutrophil count was a strong predictor of both worse DFS (aHR for recurrence/death = 2.34; 95% CI: 1.24‐4.40) and OS (aHR for death = 2.67; 95% CI: 1.51‐4.71). Among inflammatory blood indexes, while NLR was not significantly associated with DFS or OS, patients with H‐index ≥8.37 showed a higher aHR for both recurrence/death (2.82; 95% CI: 1.65‐4.79) and death (2.22; 95% CI: 1.26‐3.89). Conclusion In conclusion, the present study confirms the prognostic value of pretreatment H‐index, an easily measurable inflammatory and nutritional index, in patients with SCC of the larynx.
