RESUMO
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.

PURPOSE: The study aimed to identify parameters that could predict oncological and functional outcomes in patients with pT4aN0 laryngeal squamous cell carcinoma (LSCC) who underwent open partial horizontal laryngectomy (OPHL). The role of paratracheal neck dissection (PTND) was analyzed as the primary outcome. Additionally, the study compared the outcomes of patients who underwent postoperative radio/chemotherapy (PORT/PORCT) with those who refused or did not adhere to adjuvant treatments. METHODS: Twenty-nine OPHL patients whose pathological exam was consistent with pT4aN0-x disease were enrolled and their clinical charts were retrospectively reviewed. The study analyzed oncological outcomes, such as local, regional, and distant recurrence rates (RR), overall survival (OS), disease-free survival (DFS), and disease-specific survival (DSS). Additionally, functional results were analyzed, including decannulation rate, hospitalization time, and postoperative complication rate. RESULTS: The study revealed and overall recurrence rate of 27%. The final rates for OS and DSS were 68% and 79%, respectively. Based on the univariate analysis the PTND was significantly associated with longer DFS. No significant differences inoncological outcomes were observed between pT4a patients who underwent adjuvant radio/radiochemotherapy and those who did not, in terms of RR, DFS, DSS or OS. However, adjuvant treatment was found to significantly increase decannulation time. CONCLUSIONS: In a properly super-selected subgroup of patients with pT4aN0 LSCC, OPHL may beconsidered as a conservative surgical option even without adjuvant treatment. However, for optimal oncological outcomes, it is strongly recommended to consider a central compartment dissection in cases of hypoglottic and anterior extra-laryngeal tumor extension.
RESUMO
Objectives: To identify pre-operative radiological parameters that are able to predict the functional outcomes of open partial horizontal laryngectomy (OPHL). Methods: The present retrospective study concerned a cohort of 96 patients with laryngeal squamous cell carcinoma who underwent pre-operative radiological staging with contrast-enhanced computerised tomography of the neck, and subsequent supracricoid or supratracheal laryngectomy. Univariate and multivariate analyses were run to assess the prognostic value of the main demographic and surgical variables, and the pre-operative cephalometric values, respectively, in terms of predicting patients' functional outcomes. Results: Multivariate analysis showed that a larger anteroposterior cross-sectional dimension of the aero-digestive tract in the mid-retroglossal area, and a greater distance between the genial tubercle and the hyoid bone in the mid-sagittal plane correlated significantly with better functional outcomes in terms of decannulation rate at discharge. Conclusions: Our findings show that larger pre-operative upper aero-digestive tract diameters and volumes coincide with better post-operative functional outcomes after OPHL.

Importance: An altered sense of smell and taste has been reported to be associated with coronavirus disease 2019 (COVID-19). To understand the evolution of these symptoms during the course of the disease is important to identify patients with persistent loss of smell or taste and estimate the impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on the burden of olfactory and gustative dysfunctions. Objective: To evaluate the evolution of the loss of sense of smell and taste in a case series of mildly symptomatic patients with SARS-CoV-2 infection. Design, Setting, and Participants: This cross-sectional survey-based study included 202 mildly symptomatic adults (≥18 years) consecutively assessed at Treviso Regional Hospital, Italy, between March 19 and March 22, 2020, who tested positive for SARS-CoV-2 RNA by polymerase chain reaction on nasopharyngeal and throat swabs. Main Outcomes and Measures: Prevalence of altered sense of smell and taste at follow-up and their variation from baseline. Results: Of 202 patients completing the survey at baseline, 187 (92.6%) also completed the follow-up survey (103 [55.1%] women; median age, 56 years). The evaluation of the evolution of altered sense of smell or taste in the 113 patients reporting sudden onset of these symptoms at baseline showed that 55 patients (48.7%; 95% CI, 39.2-58.3) reported complete resolution of smell or taste impairment, 46 (40.7%; 95% CI, 31.6-50.4) reported an improvement in the severity, and only 12 (10.6%; 95% CI, 5.6-17.8) reported the symptom was unchanged or worse. Persistent loss of smell or taste was not associated with persistent SARS-CoV-2 infection. Conclusions and Relevance: At 4 weeks from the onset, 89% of the SARS-CoV-2-positive mildly symptomatic patients who had had a sudden onset of altered sense of smell or taste experienced a complete resolution or improvement of these symptoms. Persistent loss of smell or taste was not associated with persistent SARS-CoV-2 infection.
