Objective: To assess the utility of an intraoperative scoring system for mucormycosis and to predict prognosis by comparing the score with postoperative outcomes.
Methods: This study was conducted among 80 patients with mucormycosis who underwent surgical management with mandatory pterygopalatine fossa and infratemporal fossa exploration. All cases were scored using our intraoperative scoring assessment tool. Postoperative outcomes in terms of favourable prognosis and mortality were evaluated and compared with demographics, clinical history and intraoperative findings.
Results: An intraoperative score of more than 25 was statistically significant in predicting mortality (p < 0.0001). In all, 86.7% of patients with a score above 25 succumbed to the disease. Statistical significance of mortality (p < 0.05) was observed in those with involvement of pterygopalatine fossa (78.9%), orbit (73.7%), infratemporal fossa (57.9%), cribriform plate (36.8%) and those with history of intake of antiviral drugs (47.4%), use of supplemental oxygen (31.6%) and renal failure (26.3%).
Conclusions: This study enabled better prediction of postoperative prognosis in mucormycosis and reiterated the importance of exploration of pterygopalatine fossa and infratemporal fossa in management and prognostication of invasive fungal sinusitis.

Objective: This study aims to use the maximum standardised uptake value (SUVmax) of 18F-fluorodeoxyglucose positron emission tomography to improve the cost effectiveness of nimotuzumab (NTZ) in locoregionally advanced nasopharyngeal carcinoma (LA-NPC).
Methods: Two hundred and forty-eigh patients with LA-NPC, who met the inclusion criteria, were recruited from January 2012 to June 2019. The survival differences and independent factors were assessed using the Kaplan-Meier method and by Cox proportional hazards regression analysis. A cost effectiveness analysis was performed.
Results: The optimal cut-off value for SUVmax was 12.92. Multivariable analysis indicated a prognostic significance of overall survival (OS) for the NTZ treatment (p = 0.023) and SUVmax (p = 0.014). The exploratory subgroup survival analysis revealed that LA-NPC patients with SUVmax > 12.92 treated with concurrent chemoradiotherapy (CCRT) and NTZ had a significantly improved 3-year OS compared to patients treated with CCRT alone (96.2 vs 73.2%, p = 0.047). Furthermore, the treatment cost for NTZ was $6,317.61. This incurred an additional cost of $274.68 for every 1% increase in OS.
Conclusions: For patients with LA-NPC with SUVmax > 12.92, the addition of NTZ to CCRT can improve OS and is cost effective.

Objective: The aim of this study was to estimate the level of knowledge, attitudes, and practices regarding laryngopharyngeal reflux (LPR) among primary healthcare (PHC) physicians in Saudi Arabia.
Methods: This quantitative cross-sectional study used an online-based questionnaire distributed to physicians in PHC facilities and hospitals in Saudi Arabia. The questionnaire consisted of four sections that provided data on demographics, knowledge, attitudes, and practices.
Results: Of the 473 physicians included in the study, one-third were unaware of LPR, and two-thirds were unfamiliar with the reflux symptom index (RSI). The most common sources of LPR knowledge were textbooks and literature (49.8%). The most recognised risk factor, symptom, and complication were high body mass index (75.8%), voice problems (82.4%), and laryngeal cancer (70.6%), respectively. The most recognised diagnostic and treatment options were laryngoscopy (73.5%) and lifestyle modifications (87.3%), respectively, while only 60.4% of participants recognised proton pump inhibitors as a treatment option. Most PHC physicians believed that LPR is underdiagnosed and that primary prevention and awareness among the general population need to be improved.
Conclusions: One in three PHC physicians knew nothing about LPR, and two in three were unfamiliar with the RSI. More than half could not recognise all major symptoms of LPR, which might be a cause for concern, as recognising these symptoms is crucial for proper diagnosis. We recommend increasing the education of physicians about LPR, its signs and symptoms, and the RSI, all of which provide valuable clues for diagnosis.

Objectives: To investigate the expression of hypoxia-inducible factor-1α (HIF-1α) in patients with refractory sudden sensorineural hearing loss (SSNHL).
Material and methods: Thirty patients with refractory SSNHL were treated with intratympanic methylprednisolone perfusion (IMP) for 10 days. Expression of HIF-1α and histone deacetylase 2 (HDAC2) was evaluated in peripheral blood mononuclear cells (PBMCs) and in vitro.
Results: Significant hearing improvement (≥ 15 dB) was observed in 16 patients [IMP glucocorticoid sensitive (GCS) group], while 14 patients had no therapeautic hearing recovery [IMP GC resistance (GCR) group]. The expression of HDAC2 decreased and HIF-1a increased in all refractory SSNHL patients before IMP. The expression of HDAC2 and HIF-1α after IMP was significantly changed in the GCS group, but not in the GCR group. The same expression profile was also observed in House Ear Institute-organ of Corti-1 (HEI-OC1) cells exposed to oxidative stress (OS). The results of gene manipulation experiments indicate that HIF-1α up-regulation significantly reduced HDAC2 expression in HEI-OC1 cells, especially under conditions of OS.
Conclusions: This study suggests that HIF-1α activation inhibits HDAC2 expression, causing glucocorticoid resistance in refractory SSNHL. HIF-1α might serve as a potential biomarker to predict prognosis of refractory SSNHL.

Objectives: The purpose of this study is to present the long-term functional swallowing outcomes of various surgical approaches to oral tongue/floor of mouth squamous cell carcinoma (OTFOMSCC) according to a modular and compartment-based concept previously described elsewhere.
Methods: A retrospective study was conducted on patients undergoing surgery for OTFOMSCC from January 2017 to April 2023 in the Department of Otorhinolaryngology at the Hospital of Bolzano. Functional swallowing outcomes and quality of life (QoL) were assessed through the administration of a scale and questionnaires between 6 months and 1 year postoperatively or after the end of adjuvant therapy, stratifying the results according to the surgical technique used.
Results: A total of 92 patients with OTFOMSCC were enrolled: 44 patients underwent transoral anatomically guided surgery (TAGS) for early-stage tumours, and 48 underwent major surgery for advanced stages. Among the latter 48 patients: 35 underwent compartment tongue surgery (CTS), 3 underwent extended glossectomies (EG) Type A, 6 underwent EG Type B, and 4 underwent EG Type C. After TAGS, all patients resumed oral feeding for all consistencies. In the CTS group, only one patient faced challenges with pure liquids, yet all achieved the target of consuming a semisolid and semiliquid diet. EG exhibited a noticeable decline in performance from Type A to total glossectomy (Type C).
Conclusions: Following an anatomically-guided approach to the resection of OTFOMSCC allows the surgery to be modulated on the structures involved by the tumour, thus achieving optimal oncological results, while maintaining the possibility to predict functional outcomes and postoperative QoL.

Objective: We report the management of recurrent respiratory papillomatosis (RRP) employing a protocol that includes both office-based (OB) and general anaesthesia (GA) procedures. Quality of life (QoL) outcomes in the OB cohort were compared to those obtained from an historical cohort treated only under GA.
Methods: Patients affected by RRP from 2019 until 2023 ("new protocol") and from 2012 to 2019 ("historical protocol") were enrolled. In both groups the Derkay site score (DSS) was calculated. In patients adhering to the new protocol, questionnaires measuring QoL were prospectively administered (voice handicap hindex-10 [VHI-10] along with a specific questionnaire to measure the tolerance to the OB procedures). A cost analysis was also performed.
Results: In all, 35 patients composed the new protocol cohort and 13 the historical. In the first group, patients underwent a median of 4 treatments. At 2 years, 68% of patients were treated exclusively in the office. Overall, for the new protocol, median DSS and VHI-10 after one year were both significantly lower than those at baseline [2 vs 4 and 3 vs 14, respectively; p < 0.001]. No differences were found between the new and the historical protocol cohorts considering DSS over time.
Conclusions: Treatment of RRP may be conducted successfully in an office-based setting reducing healthcare costs.

Objective: This study evaluated the expression of TIM-3 and its influence on macrophage polarisation in recalcitrant chronic rhinosinusitis with nasal polyps (CRSwNP).
Methods: We detected TIM-3 expression in serum and tissue samples of healthy controls (HC), primary CRSwNP, and patients with recurrent CRSwNP. Macrophage markers were detected among three groups, and their correlations with TIM-3 levels were examined. Macrophages from circulating blood were collected and used to examine the impact of TIM-3 on polarisation in vitro.
Results: TIM-3 levels were enhanced in the CRSwNP group compared to the HC group. Tissue immunofluorescence revealed elevated TIM-3 expression in patients with CRSwNP, and patients with multiple recurrences exhibited higher TIM-3 levels compared to their first recurrence and baseline levels. Tissue CD163 and CD206 levels were higher in recurrent CRSwNP in comparison with primary cases and HCs, and had a positive correlation with TIM-3 levels. TIM-3 overexpression promoted M2 polarisation and enhanced TGF-β1 and IL-10 secretion.
Conclusions: TIM-3 expression was enhanced in patients with CRSwNP, especially in those undergoing revision surgeries. TIM-3 may be a novel biomarker for recalcitrant CRSwNP. TIM-3-driven M2 polarisation might be involved in the mechanisms of recurrent CRSwNP.
