Objectives/Hypothesis: To identify a clinical predictor score for difficult laryngeal exposure (DLE) during operative microlaryngoscopy.Study Design: Prospective cohort study in two academic institutions. Methods: We evaluated 319 patients before microlaryngoscopy for benign and malignant glottic diseases by a standardized preoperative assessment protocol (Laryngoscore) that included 11 parameters: interincisors gap (IIG), thyro-mental distance, upper jaw dental status, trismus, mandibular prognathism, macroglossia, micrognathia, degree of neck flexionextension, history of previous open-neck and/or radiotherapy, Mallampati's modified score, and body mass index (BMI). Each parameter was assessed to obtain a total score. Patients were divided into five classes according to the anterior commissure (AC) visualization: class 0, complete AC visualization with large-bore laryngoscopes in the Boyce-Jackson position; class I, as class 0 with external laryngeal counterpressure; class II, as class I in the flexion-flexion position; class III, as class II using small-bore laryngoscopes; and class IV, impossible AC visualization.Results: Class 0-I-II (good/acceptable laryngeal exposure) presented a median score < 6. This value was chosen as cutoff for distinguishing favorable versus difficult/impossible laryngeal exposures. When the Laryngoscore was < 6, good laryngeal exposure was observed in 94% of patients, whereas when 6, DLE was encountered in 40%. When considering a Laryngoscore of 9, 67% of patients had a DLE. At univariate analysis, IIG, upper jaw dental status, macroglossia, micrognathia, degree of neck flexion-extension, and BMI statistically impacted on DLE (P < 0.05).Conclusions: The Laryngoscore is a good predictor of DLE and assists in selecting the ideal candidates for operative microlaryngoscopy.

Routine use of intraoperative NBI increases the accuracy of neoplastic superficial spreading evaluation during TLM for early glottic cancer.

Even though the overall success rate of TRA/CTRA is high, it should always be regarded as a major surgical procedure with a non-negligible incidence of complications.

Aim of this study was to retrospectively analyze oncologic and functional results of a cohort of T2 and selected T3 glottic tumors treated by transoral laser surgery (TLS). Eighty-nine patients affected by T2 and T3 glottic tumors were treated by TLS from 2005 to 2010 at an academic institution by Type V cordectomies using an "en bloc" or, more frequently, a "piece-meal" technique depending on a number of variables. Kaplan-Meier curves were used to evaluate 5-year overall, disease-specific survivals, local control with laser, and organ preservation rates. Univariate analysis of the impact of different variables was performed. At least 1 year after surgery, we examined: subjective voice evaluation by voice handicap index (VHI), perceptive analysis by GRBAS scale, objective measurements with multidimensional voice program (MDVP), swallowing assessment with the M.D. Anderson Dysphagia Inventory (MDADI), videonasal endoscopic evaluation of swallowing (VEES), and videofluoroscopy (VFS). Fifty-nine patients were pT2 and 30 pT3. The 5-year overall, disease-specific survivals, local control with laser, and organ preservation rates were 92.4, 98.7, 68.5, and 82.1 %, respectively. VHI mean score was 20 (mild dysphonia). Mild and moderate dysphonias were detected by GRBAS in 82 and 18% of patients, respectively. Mean values of Jitter, Shimmer, and noise-to-harmonic ratio by MDVP resulted 7.87%, 24.8%, and 0.37, respectively. Mean value of MDADI was 95.75. Only 2% of patients at VEES and 4% at VFS showed tracheal aspiration. Our results highlight that T2 and selected T3 glottic tumors treated by TLS have favorable oncologic and functional outcomes.
