RESUMO

INTRODUCTION: Patulous Eustachian tube (PET) is a condition affecting approximately 0.3% to 6.6% of the population, with autophony being the predominant complain. The management of PET lacks a well-defined standard in the literature as no effective medical treatments have been documented but various surgical options are available. This study aims to report mid-term outcomes following surgical management of PET. MATERIALS AND METHODS: All patients who underwent surgical intervention for PET between September 2017 and June 2022 were enrolled. Data encompassing general demographics, quality of life (GBI), and procedure-specific data were collected. RESULTS: A total of 30 PET cases (in 19 patients) underwent surgical intervention including 9 injections of hyaluronic acid, 13 fat injections, 6 endoscopic shim insertions, 1 cartilage graft, and 1 injection of hydroxy apatite. After an average follow-up of 22 ± 14 months, 16 cases (53%) achieved complete symptom relief, while 8 cases (26.6%) reported partial relief. Additionally, 11(36%) cases required multiple surgeries. No specific surgical technique demonstrated superiority. Quality of life improved in 77% of cases based on 10 out of 13 GBI collected. Recurrence of PET symptoms occurred on average 10.6 ± 9.7 months after initial surgery, with an estimated global risk of 75% at 3 years. Transient serous otitis media was observed in only 4 cases (13.3%). CONCLUSION: Surgical intervention for PET was found to be effective, achieving complete symptom relief in 53% of cases and significantly improving quality of life 2 years post-surgery. However, a substantial portion of cases necessitated one or more re-interventions. The durability of effectiveness appears to diminish over time.

RESUMO

Although it is the gold standard for assessing the malignancy of thyroid nodules (TNs) preoperatively, the cytological analysis of fine-needle aspiration cytology (FNAC) samples results in 20-30% of cases in indeterminate lesions (ITNs). As two-thirds of these lesions will appear benign after diagnostic surgery, improved preoperative diagnostic methods need to be developed. In this pilot study, we evaluate if the metabolomic profiles of liquid-based (CytoRich®) FNAC samples of benign and malignant nodules can allow the molecular diagnosis of TNs. We performed untargeted metabolomic analyses with CytoRich® FNAC in a monocentric retrospective study. The cohort was composed of cytologically benign TNs, histologically benign or papillary thyroid carcinomas (PTCs) cytologically ITNs, and suspicious/malignant TNs histologically confirmed as PTCs. The diagnostic performance of the identified metabolomic signature was assessed using several supervised classification methods. Seventy-eight patients were enrolled in the study. We identified 7690 peaks, of which 2697 ions were included for further analysis. We selected a metabolomic signature composed of the top 15 metabolites. Among all the supervised classification methods, the supervised autoencoder deep neural network exhibited the best performance, with an accuracy of 0.957 (0.842-1), an AUC of 0.945 (0.833-1), and an F1 score of 0.947 (0.842-1). Here, we report a promising new ancillary molecular technique to differentiate PTCs from benign TNs (including among ITNs) based on the metabolomic signature of FNAC sample fluids. Further studies with larger cohorts are now needed to identify a larger number of biomarkers and obtain more robust signatures.

RESUMO

A growing incidence of differentiated thyroid cancer (DTC) has been reported in most developed countries, corresponding mainly to incidentally discovered small papillary thyroid carcinomas. Given the excellent prognosis of most patients with DTC, optimal therapeutic management, minimizing complications, and preserving patient quality of life are essential. Thyroid surgery has a central role in both the diagnosis, staging, and treatment of patients with DTC. Thyroid surgery should be integrated into the global and multidisciplinary management of patients with DTC. However, the optimal surgical management of DTC patients is still controversial. In this review article, we discuss the recent advances and current debates in DTC surgery, including preoperative molecular testing, risk stratification, the extent of thyroid surgery, innovative surgical tools, and new surgical approaches.

RESUMO

OBJECTIVE: Indeterminate thyroid nodules (ITN) are common and often lead to (sometimes unnecessary) diagnostic surgery. We aimed to evaluate the performance of two machine learning methods (ML), based on routinely available features to predict the risk of malignancy (RM) of ITN. DESIGN: Multi-centric diagnostic retrospective cohort study conducted between 2010 and 2020. METHODS: Adult patients who underwent surgery for at least one Bethesda III-V thyroid nodule (TN) with fully available medical records were included. Of the 7917 records reviewed, eligibility criteria were met in 1288 patients with 1335 TN. Patients were divided into training (940 TN) and validation cohort (395 TN). The diagnostic performance of a multivariate logistic regression model (LR) and its nomogram, and a random forest model (RF) in predicting the nature and RM of a TN were evaluated. All available clinical, biological, ultrasound, and cytological data of the patients were collected and used to construct the two algorithms. RESULTS: There were 253 (19%), 693 (52%), and 389 (29%) TN classified as Bethesda III, IV, and V, respectively, with an overall RM of 35%. Both cohorts were well-balanced for baseline characteristics. Both models were validated on the validation cohort, with performances in terms of specificity, sensitivity, positive predictive value, negative predictive value, and area under the receiver operating characteristic curve of 90%, 57.3%, 73.4%, 81.4%, 84% (CI95%: 78.5%-89.5%) for the LR model, and 87.6%, 54.7%, 68.1%, 80%, 82.6% (CI95%: 77.4%-87.9%) for the RF model, respectively. CONCLUSIONS: Our ML models performed well in predicting the nature of Bethesda III-V TN. In addition, our freely available online nomogram helped to refine the RM, identifying low-risk TN that may benefit from surveillance in up to a third of ITN, and thus may reduce the number of unnecessary surgeries.

RESUMO

INTRODUCTION: Mandibular anterior subapical osteotomy (MASO) is a complementary procedure during orthognathic surgery to correct proclination or extrusion of the anterior incisors when orthodontic movements fail. The increasing use of patient-specific implants (PSI, titanium plates) in orthognathic surgery has extended to this procedure. Digital orthognathic surgery planning involves manufacturing cutting/drilling guides and specific implants to provide better accuracy and allow complex movement with reduced surgical times compared to conventional planning. This study aimed to assess the accuracy of computer-aided surgery with patient-specific implants in mobilising the MASO segment according to planning. METHODS: Eleven consecutive patients with mean age 26.82 years (15-41, SD = 10.65) were treated with MASO in addition to other conventional orthognathic procedures incorporating digital planning and patient-specific implants. A three-dimensional "stl" format file of the mandibular dental arch was obtained using an intraoral scanner at the end of the surgical procedure. The accuracy of the MASO segment displacement imposed by PSI was assessed by comparing preoperative 3D-planned mandibular dental arch with the immediate postoperative 3D-measured arch, using surface superimposition and 7 standard dental landmarks. Deviations between the preoperative and postoperative landmarks were calculated and compared to determine whether MASO segment repositioning is sufficiently accurate to be safely used to reposition the incisor/canine axis. RESULTS: Quantitative analysis revealed an absolute linear difference of 0.66 mm (SD = 0.51) between preoperative 3D digital dental arch impression and postoperative planned 3D dental arch. Overall, the median absolute discrepancies in the x-axis (right-left direction), y-axis (antero-posterior direction), and z-axis (supero-inferior direction) were respectively 0.56 mm (SD = 0.42), 0.77 mm (SD = 0.45) and 0.65 mm (SD = 0.61). CONCLUSION: A high degree of accuracy between the virtual plan and the immediate postoperative result was observed. According to our results, PSI can be used safely with accuracy in MASO as an adjunct to other conventional orthognathic procedures.

RESUMO

Hippocrates, a Greek physician during the fifth century BC., is often considered the father of medicine. The Corpus Hippocraticum comprising of 58 volumes was writing between 450 and 150 BC. The objective of our study was to detail the management of nasal polyps during this period. We read and analyzed all volumes of the Corpus Hippocraticum in French translation and extracted all passages dealing with nasal polyps (n = 6). Surgical procedures in the Corpus Hippocraticum are described in great detail. The first surgical strategy for the removal of nasal polyps was by mini-invasive nasal approach: the lopping method and the sponge method. We explain the two mini-invasive nasal approaches with drawings. The meticulously detailed observations of the corpus give us a precious insight into the early perception of diseases, their progression and early attempts of treatment.

RESUMO

BACKGROUND: Transoral robotic surgery (TORS) is an emerging minimally invasive surgical treatment for residual, recurrent, and new primary head and neck cancers in previously irradiated fields, with limited evidence for its oncological effectiveness. METHODS: A retrospective observational cohort study of consecutive cases performed in 16 high-volume international centers before August 2018 was conducted (registered at clinicaltrials.gov [NCT04673929] as the RECUT study). Overall survival (OS), disease-free survival, disease-specific survivals (DSS), and local control (LC) were calculated using Kaplan-Meier estimates, with subgroups compared using log-rank tests and Cox proportional hazards modeling for multivariable analysis. Maximally selected rank statistics determined the cut point for closest surgical resection margin based on LC. RESULTS: Data for 278 eligible patients were analyzed, with median follow-up of 38.5 months. Two-year and 5-year outcomes were 69.0% and 62.2% for LC, 71.8% and 49.8% for OS, 47.2% and 35.7% for disease-free survival, and 78.7% and 59.1% for disease-specific survivals. The most discriminating margin cut point was 1.0 mm; the 2-year LC was 80.9% above and 54.2% below or equal to 1.0 mm. Increasing age, current smoking, primary tumor classification, and narrow surgical margins (≤1.0 mm) were statistically significantly associated with lower OS. Hemorrhage with return to theater was seen in 8.1% (n = 22 of 272), and 30-day mortality was 1.8% (n = 5 of 272). At 1 year, 10.8% (n = 21 of 195) used tracheostomies, 33.8% (n = 66 of 195) used gastrostomies, and 66.3% (n = 53 of 80) had maintained or improved normalcy of diet scores. CONCLUSIONS: Data from international centers show TORS to treat head and neck cancers in previously irradiated fields yields favorable outcomes for LC and survival. Where feasible, TORS should be considered the preferred surgical treatment in the salvage setting.

RESUMO

OBJECTIVES: The objective of this review was to determine the rate and risk factors of paratracheal lymph node (PTLN) involvement during total laryngectomy (TL) or total pharyngolaryngectomy (TPL). In addition, we aimed to assess its prognostic significance in terms of survival and peristomal recurrence. METHODS: A comprehensive electronic search was performed on PubMed, EMBASE, and CENTRAL databases. We searched for studies reporting outcomes of PTLN dissection during radical laryngeal surgery for squamous cell carcinoma of the larynx, hypopharynx or cervical oesophagus. RESULTS: We included a total of ten studies (838 patients). The overall rate of PTLN dissection positivity was 18.6% (20.7% for primary TL, 8.7% for salvage TL). Random-effects meta-analysis identified T4 stage, N+ stage of the lateral neck, subglottis involvement and primary tumour arising from the hypopharynx or cervical oesophagus as significant risk factors for PTLN involvement. CONCLUSIONS: This meta-analysis allowed to better define the risk of PTLN involvement during TL or TPL, in a bid to guide indication for PTLN dissection. There is a need for further large studies reporting rigorously the outcomes of PTLN dissection in order to establish stronger evidence-based recommendations.

RESUMO

(1) Background: Persistent post-viral olfactory disorders (PPVOD) are estimated at 30% of patients one year after COVID-19 infection. No treatment is, to date, significantly effective on PPVOD with the exception of olfactory training (OT). The main objective of this work was to evaluate OT efficiency on post-COVID-19 PPVOD. (2) Methods: Consecutive patients consulting to the ENT department with post-COVID-19 PPVOD were included after completing clinical examination, the complete Sniffin' Stick Test (TDI), the short version of the Questionnaire of olfactory disorders and the SF-36. Patients were trained to practice a self-olfactory training with a dedicated olfactory training kit twice a day for 6 months before returning to undergo the same assessments. (3) Results: Forty-three patients were included and performed 3.5 months of OT in average. We observed a significant TDI score improvement, increasing from 24.7 (±8.9) before the OT to 30.9 (±9.8) (p < 0.001). Based on normative data, a significant increase in the number of normosmic participants was observed only for the threshold values (p < 0.001). Specific and general olfaction-related quality of life improved after the OT. (4) Conclusions: Olfactory function appeared to improve only in peripheral aspects of post-COVID-19 PPVOD after OT. Future controlled studies must be performed to confirm the OT role and justify new therapeutic strategies that may focus on the central aspects of post-COVID-19 PPVOD.

RESUMO

At a time when complex diseases affect globally 280 million people and claim 14 million lives every year, there is an urgent need to rapidly increase our knowledge into their underlying etiologies. Though critical in identifying the people at risk, the causal environmental factors (microbiome and/or pollutants) and the affected pathophysiological mechanisms are not well understood. Herein, we consider the variations of autophagy-related (ATG) genes at the heart of mechanisms of increased susceptibility to environmental stress. A comprehensive autophagy genomic resource is presented with 263 single nucleotide polymorphisms (SNPs) for 69 autophagy-related genes associated with 117 autoimmune, inflammatory, infectious, cardiovascular, neurological, respiratory, and endocrine diseases. We thus propose the term 'autophagopathies' to group together a class of complex human diseases the etiology of which lies in a genetic defect of the autophagy machinery, whether directly related or not to an abnormal flux in autophagy, LC3-associated phagocytosis, or any associated trafficking. The future of precision medicine for common diseases will lie in our ability to exploit these ATG SNP x environment relationships to develop new polygenetic risk scores, new management guidelines, and optimal therapies for afflicted patients.Abbreviations: ATG, autophagy-related; ALS-FTD, amyotrophic lateral sclerosis-frontotemporal dementia; ccRCC, clear cell renal cell carcinoma; CD, Crohn disease; COPD, chronic obstructive pulmonary disease; eQTL, expression quantitative trait loci; HCC, hepatocellular carcinoma; HNSCC, head and neck squamous cell carcinoma; GTEx, genotype-tissue expression; GWAS, genome-wide association studies; LAP, LC3-associated phagocytosis; LC3-II, phosphatidylethanolamine conjugated form of LC3; LD, linkage disequilibrium; LUAD, lung adenocarcinoma; MAF, minor allele frequency; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; NSCLC, non-small cell lung cancer; OS, overall survival; PtdIns3K CIII, class III phosphatidylinositol 3 kinase; PtdIns3P, phosphatidylinositol-3-phosphate; SLE, systemic lupus erythematosus; SNPs, single-nucleotide polymorphisms; mQTL, methylation quantitative trait loci; ULK, unc-51 like autophagy activating kinase; UTRs, untranslated regions; WHO, World Health Organization.

RESUMO

OBJECTIVE: We investigated the quality of life (QoL), functional, and oncological outcomes after robotic-assisted transoral or combined cervical-transoral salvage surgery for oropharyngeal carcinoma following radiotherapy. MATERIAL AND METHODS: We performed a single tertiary referral center, prospective, observational cohort study of all consecutive patients who underwent salvage robotic-assisted surgery for oropharyngeal carcinoma between 2015 and 2021. The primary outcomes were quality of life assessments using the MDADI, EORTC-QLQC30, and EORTC-QLQH&N35. Secondary endpoints were the functional and oncological outcomes based on overall survival, disease-free survival, and local control. RESULTS: A consecutive cohort of 53 patients were included. The median Charlson comorbidity index was 5. The p16 status was negative in 87%, and 22.6% were T3-4. A flap reconstruction was performed in 90.6%, with a free flap in 67.9%. Margins were negative in 81.1%. The preoperative, 1-year, and 2-year MDADI total scores were 71.4, 64.3, and 57.5, respectively. The preoperative, 1-year, and 2-year QLQ-C30 global scores were 61.2, 59.4, and 80.6, respectively. Decannulation was possible in 97.1% of the tracheotomized patients. The two-year enteral tube dependence was 23.1%. The two-year overall survival, disease-free survival, and local control rates were 59%, 46.1%, and 80.9%, respectively. CONCLUSION: Robotic-assisted salvage surgery for oropharyngeal carcinoma following radiotherapy demonstrated a very satisfactory quality of life, good functional sequelae, and good oncological outcomes compared to historical approaches.

RESUMO

Vestibuloplasty is fundamental to restore an oral vestibule for immediate dental implantation in fibular free flap (FFF) for oral cancer patients undergoing mandibulectomy reconstruction. Double surgical team including reconstructive head and neck surgeon and a dental surgeon is fundamental. The first step of the vestibuloplasty is to identify the skin perforator. The second step is to thin the FFF skin island as much as necessary to facilitate: i-the reinset into the gingivobuccal sulcus while creating enough space in the oral vestibule for the future dental prosthesis and ii-the exposition of dental implants. The third step is to create a percutaneous access to the implants through the FFF skin paddle using a dermatologic punch while preserving a large oral vestibule. The fourth step is the skin reinsertion into the gingivobuccal sulcus and closure. Realizing vestibuloplasty before radiotherapy allows prevention of soft tissue contraction and osteoradionecrosis while reducing the necessary time for a complete dental rehabilitation and improving patient quality of life.

RESUMO

BACKGROUND: Post-COVID-19 Olfactory impairment has a negative impact on quality of life. The Sniffin Sticks test 12 items (SST-12) can be used in quick olfactory disorders screening. Its evaluation in a post-covid-19 situation was the main objective of this work. METHODS: All patient impaired with a post-COVID olfactory loss were included while consulting to the ENT department. The clinical examination included an olfaction recovery self-assessment (VAS), a nasofibroscopy, a quality of life (QoL) assessment, the complete Sniffin' Sticks Test (SST), and the SST-12. RESULTS: Among the 54 patients included, 92% (n = 50) were correctly screened as olfactory impaired by SST-12. We report excellent correlations between SST-12 and SST (rho (52) = 0.98, p < 0.001), QoL(rho(52) = 0.33 p = 0.016), or VAS (rho(52) = 0.49, p < 0.001) assessments. CONCLUSIONS: SST-12 is a quick and reliable tool to screen large-scale population of post-COVID-19 olfactory impaired patients and could be used in a general daily clinical practice.

RESUMO

OBJECTIVES: To highlight the specific outcomes of the current surgical procedures for lingual thyroid excision, for benign and malignant lesions. METHODS: We carried out a systematic review of surgical treatments of lingual thyroid, according to the PRISMA method. We conducted our literature search in PubMed and Ovid. Data was collected concerning patient demographics, tumor characteristics, types of surgery performed, and specific intra- and postoperative outcomes of each procedure. Surgical procedures were classified in 4 categories: transcervical approaches, "invasive" transoral approaches (transmandibular and/or tongue splitting), "non-invasive" transoral approaches, and transoral robotic surgery. We detailed the transoral robotic surgical technique through a case report, along with a surgical video. RESULTS: Of 373 peer-reviewed articles found, 40 provided adequate information on surgical management and outcomes for patients with lingual thyroid. "Non-invasive" transoral approaches and transoral robotic surgeries required significantly fewer tracheostomies than "invasive" transoral and transcervical approaches (P < .001), while there was no statistical difference in the rate of surgical complications between each procedure. CONCLUSIONS: Transoral robotic surgery appears to be a feasible, effective, and fast solution for lingual thyroid excision, with excellent short- and long-term surgical outcomes.

RESUMO

The programmed cell death-1/programmed cell death ligand-1 (PD-1/PD-L1) immune checkpoint proteins hold promise as diagnostic, prognostic, and therapeutic targets for precision oncology. By restoring antitumor T cell surveillance, the high degree of effectiveness of the immune checkpoint inhibitors (ICIs) has revolutionized cancer treatment. However, the majority of patients (65-80 %) treated with ICIs experience significant side effects, called immune-related adverse events (irAEs), resulting in autoimmune damage to various organs. Therefore, broadening the clinical applicability of these treatments to all cancer types requires an improved understanding of the mechanisms linking cancer immune evasion and autoimmunity. The thyroid is the endocrine gland the most frequently involved in autoimmunity and cancer, the growing incidence of which is raising serious public health issues worldwide. In addition, the risk of developing thyroid cancer is increased in patients with autoimmune thyroid disease and thyroid dysfunction is one of the most common irAEs, especially with PD­1/PD-L1 blockade. Therefore, we chose the thyroid as a model for the study of the link between autoimmunity, irAEs, and cancer. We provide an update into the current knowledge of the PD­1/PD-L1 axis and discuss the growing interest of this axis in the diagnosis, prognosis, and management of thyroid diseases within the context of autoimmunity and cancer, while embracing personalized medicine.

RESUMO

INTRODUCTION: The proportion of elderly patients with head and neck cancer is increasing. However, predictive factors of postoperative outcomes are insufficiently explored in this population. In this study, we aimed to determine predictive factors of postoperative outcomes in elderly patients undergoing head and neck free-flap reconstructive surgery in order to determine criteria on which patient selection could be based. METHODS: All patients aged 65 years or over who underwent head and neck free-flap reconstructive surgery at our institution, between 2000 and 2016, were included in this retrospective study. Predictive factors of postoperative outcomes were investigated in uni- and multivariate analysis. RESULTS: Two-hundred patients were included in the study. Older age (>70, >75 or > 80 yrs) had no significant impact on postoperative outcomes. Free flap failure local and general complications rates were 11%, 34% and 43%, respectively. Oromandibular reconstruction (p = 0.04) was significantly associated with free flap failure and salvage surgery (p = 0.04) with local complications. A high comorbidity level (Charlson Comorbidity Index score ≥ 4; p = 0.02) was associated with a higher risk of general complications. A G8 (Geriatric 8 questionnaire) score < 15 (p = 0.004), a high comorbidity level (Kaplan-Feinstein Index score ≥ 2; p = 0.04) and oromandibular reconstruction (p = 0.04) were associated with poor swallowing function at 6 months. CONCLUSION: Head and neck free flap reconstruction should be offered to fit (G8 score ≥ 15) elderly patients without severe comorbidities (KFI < 2 or CCI < 4), particularly when oral/pharyngeal soft-tissue reconstruction is planned.

RESUMO

OBJECTIVES: To assess the factors associated with long-term quality of life (QoL) and patient concerns in elderly oral or oropharyngeal cancer (OOPC) patients after oncologic surgery and free-flap reconstruction. METHODS: Patients aged over 70 years who were still alive and disease-free at least 1 year after surgery were enrolled in this cross-sectional multicentric study. Patients completed the EORTC QLQ-C30, -H&N35 and -ELD14 QoL questionnaires, and the Hospital Anxiety and Depression Scale (HADS). Patient needs were evaluated using the Patient Concerns Inventory (PCI). Factors associated with these clinical outcomes were determined in univariate and multivariate analysis. RESULTS: Sixty-four patients were included in this study. Long-term QoL, functioning scales and patient autonomy were well-preserved. Main persistent symptoms were fatigue, constipation and oral function-related disorders. Salivary and mastication/swallowing problems were the main patient concerns. The mean number of patient concerns increased with the deterioration of their QoL. Psychological distress (HADS score ≥ 15) and patient frailty (G8 score < 15) were significantly associated with poor QoL outcomes. CONCLUSIONS: We found a negative correlation between the number of patient concerns and QoL. Dental rehabilitation and psychological and nutritional supportive measures are of critical importance in the multidisciplinary management of elderly OOPC patients.

RESUMO

OBJECTIVE: To compare otologic outcomes in patients with cleft palate who underwent 2 different surgical protocols. DESIGN: Monocentric retrospective analysis of medical reports. PATIENTS, PARTICIPANTS: All consecutively treated patients affected by a cleft palate, born between January 1998 and December 2002 (group 1) and between January 2007 and December 2010 (group 2). INTERVENTIONS: Patients in group 1 underwent Veau-Wardill-Kilner palatoplasty at 10 months and had ventilation tubes inserted in case of otitis media with effusion (OME) during surgery. Patients in group 2 underwent Sommerlad intravelar veloplasty at 5 months. Ventilation tubes were inserted only in case of persistent OME. MAIN OUTCOME MEASURE(S): The need for a second set of ventilation tubes to be inserted in case of persistent OME, the presence of OME at the age of 2 years, and tympanic abnormalities at the age of 5 years were analyzed. RESULTS: There was no statistically significant difference either for the presence of OME at the age of 2 years (27 [45%] vs 32 [57.14%], respectively, in groups 1 and 2; P = .191) or for tympanic abnormalities at the age of 5 years (20 [33.33%] vs 15 [26.79%]; P = .433). Statistically significant difference was found for the need to insert a second set of ventilation tubes in case of persistent OME (29 [48.33%] vs 12 [21.42%], respectively; P = .02). CONCLUSION: Early Sommerlad intravelar veloplasty may reduce persistent OME and consequently the need for ventilation tubes insertion, compared to later Veau-Wardill-Kilner palatoplasty.
