RESUMO

BACKGROUND: This study aims to explore the applicability of narrow-band imaging (NBI) involving the Ni classification for the diagnosis of nasopharyngeal mucosal lesions in order to distinguish malignant tumours (NPT) from non-malignant lesions. METHODS: Each patient (n = 53) with a suspected nasopharyngeal lesion underwent a trans-nasal flexible video endoscopy with an optical filter for NBI. We assessed the suspected area using white light imaging (WLI) in terms of location and morphology as well as the vascular pattern (using Ni classification of nasopharyngeal microvessels) and surrounding tissue by using NBI. Based on the results of the NBI and WLI, patients were classified into "positive" or "negative" groups. All lesions of the nasopharynx were biopsied and submitted for final histological evaluation. RESULTS: NBI showed higher sensitivity, specificity, and accuracy than WLI. There was a significant correlation between the final histological result and the NBI pattern of the NPT: Chi2(1) = 31.34; p = 0.000001 and the WLI assessment of the NPT: Chi2(1) = 14.78; p = 0.00012. CONCLUSIONS: The assessment of the NPT in NBI using Ni NBI classification proved valuable in suspected mucosa assessment. NBI not only confirms the suspicious areas in WLI, but it also shows microlesions beyond the scope of WLI and allows for proper sampling.

RESUMO

PURPOSE: As online health information-seeking surges, concerns mount over the quality and safety of accessible content, potentially leading to patient harm through misinformation. On one hand, the emergence of Artificial Intelligence (AI) in healthcare could prevent it; on the other hand, questions raise regarding the quality and safety of the medical information provided. As laryngeal cancer is a prevalent head and neck malignancy, this study aims to evaluate the utility and safety of three large language models (LLMs) as sources of patient information about laryngeal cancer. METHODS: A cross-sectional study was conducted using three LLMs (ChatGPT 3.5, ChatGPT 4.0, and Bard). A questionnaire comprising 36 inquiries about laryngeal cancer was categorised into diagnosis (11 questions), treatment (9 questions), novelties and upcoming treatments (4 questions), controversies (8 questions), and sources of information (4 questions). The population of reviewers consisted of 3 groups, including ENT specialists, junior physicians, and non-medicals, who graded the responses. Each physician evaluated each question twice for each model, while non-medicals only once. Everyone was blinded to the model type, and the question order was shuffled. Outcome evaluations were based on a safety score (1-3) and a Global Quality Score (GQS, 1-5). Results were compared between LLMs. The study included iterative assessments and statistical validations. RESULTS: Analysis revealed that ChatGPT 3.5 scored highest in both safety (mean: 2.70) and GQS (mean: 3.95). ChatGPT 4.0 and Bard had lower safety scores of 2.56 and 2.42, respectively, with corresponding quality scores of 3.65 and 3.38. Inter-rater reliability was consistent, with less than 3% discrepancy. About 4.2% of responses fell into the lowest safety category (1), particularly in the novelty category. Non-medical reviewers' quality assessments correlated moderately (r = 0.67) with response length. CONCLUSIONS: LLMs can be valuable resources for patients seeking information on laryngeal cancer. ChatGPT 3.5 provided the most reliable and safe responses among the models evaluated.

RESUMO

The goal of this paper was the evaluation of the changes in the expression profile of irisin, ghrelin, and titin in the carcinoma tissue and in the blood of patients with head and neck squamous cell carcinoma (HNSCC), including determining the profile of their expression in relation to patient nutrition. The study included 56 patients with diagnosed squamous cell carcinoma of HNSCC in the T3 and T4 stages of the disease. Healthy control tissue specimens were collected from an area 10 mm outside the histologically negative margin. In turn, the blood and serum from the control group came from healthy volunteers treated for non-oncologic reasons (n = 70). The molecular analysis allowed us to determine the profile of irisin, ghrelin, and titin methylation, evaluate their expression on the level of mRNA (quantitative Reverse Transcription Polymerase Chain Reaction; qRT-PCR) and protein (Enzyme-Linked Immunosorbent Assay Reaction; ELISA) in the carcinoma tissue and the margin of healthy tissue, as well as in serum of patients in the study and control groups. At the start of our observations, a Body Mass Index (BMI) < 18.5 was noted in 42 of the patients, while six months after the treatment a BMI < 18.5 was noted in 29 patients. We also noted a decrease in the expression of irisin, ghrelin, and titin both on the level of mRNA and protein, as well as a potential regulation of their expression via DNA methylation. There is no convincing evidence that the proteins assayed in the present work are specific with regard to HNSSC.

RESUMO

Intranasal adhesions (synechiae) develop as a result of improper healing of the nasal mucosa. Their incidence ranges from 6.8% to 36% of rhinosurgical procedures. The aim of this study was to review the available publications and monographs dealing with intranasal adhesions-both in the context of formation and risk factors. The study used a review of the literature to determine the articles and studies available in the following medical databases: MEDLINE (National Library of Medicine's), PubMed, and Google Scholar. The following search terms were used: synechiae nasal + synechial nasal + intranasal adhesions + nasal adhesions. The time criterion of available materials was not applied. Available filters in the search engines were used to narrow down the search results. Artificial intelligence was not applied. The review indicated that the risk of intranasal adhesions correlates with the type of surgery, the surgical technique, the dressing materials, and wound care in the postoperative period. Every case requires an individualized approach. Nasal septum separators, (self-)dissolving dressings and (in selected cases) Mitomycin C were investigated thoroughly. Further studies are required which may result in a universal classification system for intranasal adhesions.

RESUMO

OBJECTIVES: To investigate the impact on local relapse rate (LRR) and disease specific survival (DSS) of intraoperative margins (FS) obtained by circumferential sampling method, corresponding to the lesion shape and marked using clock-face orientation combined with narrow band imaging (NBI) in head and neck squamous cell carcinoma Materials and Methods: 147 consecutive patients who underwent primary surgery with radical intent for oral and oropharyngeal cancer between 2011 and 2016 were prospectively enrolled. Patients were assigned to 3 groups with different sampling methods. In group A (n=44) a classical FS sampling method was used. In group B (n=73), the clock-face orientation sampling method (FS oclock) was used, whereas in group C (n=30), the FS oclock method combined with NBI. The primary outcome measure was the interdependence between FS sampling methods and oncological outcomes measured by LRR and DSS. RESULTS: In total, 1534 FS samples were obtained with range of 3-24 FS taken per case, median 7.25 in group A, 8.15 in group B and 7.52 in group C. When compared FS histology and final histology in all groups the sensitivity, specificity and accuracy were 61.54%, 98.51% and 95.24%, respectively. The overall LRR equaled 8.8%. The lowest LRR was observed in FS oclock method combined with NBI (6.67%) followed by FS oclock (6.85%) and FS classic (13.64%). For all patients, DSS achieved 95.92% - 95.45% in FS classic, 95.89% in FS oclock and 96.67%. in FS oclock combined with NBI. CONCLUSION: The FS oclock sampling method combined with NBI increases the chance of achieving tumor-negative margins and in result improves the treatment outcome reflected by LRR and DSS.

RESUMO

Abstract Introduction: Trans-oral laser microsurgery is an established technique for the treatment of early and moderately advanced laryngeal cancer. Objective: The authors intend to test the usefulness of narrow-band imaging in the intraoperative assessment of the larynx mucosa in terms of specifying surgical margins. Methods: Forty-four consecutive T1-T2 glottic cancers treated with trans-oral laser microsurgery Type I-VI cordectomy were presented. Suspected areas (90 samples/44 patients) were biopsied under the guidance of narrow-band imaging and white light and sent for frozen section. Results: Our study revealed that 75 of 90 (83.3%) white light and narrow-band imaging-guided samples were histopathologically positive: 30 (40%) were confirmed as carcinoma in situ or invasive carcinoma and 45 (60%) as moderate to severe dysplasia. In 6 patients mucosa was suspected only in narrow-band imaging, with no suspicion under white light. Thus, in these 6 patients 18/90 (20%) samples were taken. In 5/6 patients 16/18 (88.8%) samples were positive in frozen section: in 6/18 (33.3%) carcinoma (2 patients), 10/18 (66.6%) severe dysplasia was confirmed (3 patients). In 1 patient 2/18 (11.1%) samples were negative in frozen section. Presented analysis showed, that sensitivity, specificity and accuracy of white light was 79.5%, 20% and 71.1% respectively, while narrow-band imaging was 100%, 0.0% and 85.7%, respectively. Conclusion: The intraoperative use of narrow-band imaging proved to be valuable in the visualization of suspect areas of the mucosa. Narrow-band imaging confirms the suspicions undertaken in white light and importantly, it showed microlesions beyond the scope of white light.


Resumo Introdução: A microcirurgia transoral a laser é uma técnica bem estabelecida para o tratamento de câncer de laringe inicial e moderadamente avançado. Objetivo: Verificar a utilidade da imagem de banda estreita na avaliação intraoperatória da mucosa laríngea na especificação das margens cirúrgicas. Método: Foram avaliados 44 cânceres glóticos T1-T2 consecutivos, tratados com cordectomia Tipo I-VI, por microcirurgia transoral a laser. As áreas suspeitas (90 amostras/44 pacientes) foram submetidas a biopsia e avaliadas através de imagens de banda estreita e luz branca e enviadas para cortes por congelação. Resultados: Nosso estudo revelou que 75 (83,3%) das 90 amostras apresentaram histopatologia positiva na análise com luz branca e imagens de banda estreita: 30 (40%) foram confirmadas como carcinoma in situ ou carcinoma invasivo e 45 (60%) como displasia moderada a grave. Em seis pacientes, a mucosa apresentou-se suspeita apenas na imagem de banda estreita, sem suspeita sob luz branca. Assim, nesses seis pacientes 18/90 (20%) amostras foram colhidas. Em 5/6 pacientes, 16/18 (88,8%) amostras mostraram resultado positivo na análise de congelação: em 6/18 (33,3%) amostras foi confirmado carcinoma (dois pacientes) e em 10/18 (66,6%) foi confirmada displasia grave (três pacientes). Em um paciente, 2/18 (11,1%) as amostras mostraram resultado negativo na congelação. A análise apresentada mostrou que a sensibilidade, a especificidade e a acurácia da luz branca foram de 79,5%, 20% e 71,1%, respectivamente, enquanto a imagem de banda estreita apresentou como resultados 100%, 0,0% e 85,7%, respectivamente. Conclusão: O uso intraoperatório de imagem de banda estreita provou ser valioso na identificação de áreas suspeitas da mucosa, confirmou as suspeitas verificadas na análise com luz branca e, o que é mais importante, identificou microlesões além do alcance da luz branca.

RESUMO

This research sought to analyze the functional results of free flap reconstruction in two groups of patients with head and neck cancer: first group started with radiochemotherapy followed by reconstructive surgery, second group underwent initiative surgery. MATERIALS AND METHODS: In a group of 100 patients, surgery was used as the primary form of treatment in 55 (55%) patients, and the remaining 45 patients (45%) had chemoradiotherapy introduced first. Statistical analysis was performed with Statistica v. 12. The chi-square test and test of proportion were used for categorical data. Student's t-test was used for continuous data. Probability of survival was calculated using the Kaplan-Meier method where the censoring variable was time to death. To compare survival between cohorts, we used the Cox's test. The level of significance was set at p < 0.05. RESULTS AND CONCLUSIONS: Initial radiochemotherapy prior to surgical treatment indicated an increased risk of local tumor recurrence, flap degeneration, and other local complications.

RESUMO

PURPOSE OF REVIEW: The aim of this article is to review the literature on medial femoral condyle (MFC) free flap in head and neck reconstruction. RECENT FINDINGS: The MFC flap is a superb material for head and neck reconstruction, especially in smaller bony defects. As an alternative to fibular free flap, it presents many advantages. Combining the periosteal bone with skin and/or muscle paddle, the MFC flap is suitable for complex reconstructions with favorable healing process. Even though this flap has a longer history of orthopedic and traumatologic reconstructions, a number of cases in head and neck surgery have been recently reported. SUMMARY: The MFC flap has been successfully used to reconstruct various head and neck sites, from the orbit, maxilla, and mandible, to the laryngeal and tracheal scaffolds.

RESUMO

Large airway reconstruction is difficult and requires a flap that will mirror the tissue variety. The main challenge is to keep the reconstruction stable and prevent collapse. In this report, we present a laryngotracheal reconstruction with a buccal mucosa-prefabricated medial femoral condyle free flap, after chondroma excision in a 1-step procedure. Functional results are promising and were confirmed by endoscopy and computed tomography examination 12 months postoperatively. This reconstruction-with-prefabrication technique, among others, may be used in the reconstruction of different regions like craniofacial bone defects, apart from larynx and trachea.

RESUMO

Identification of the association between tissue biomarkers, their surrogates in blood and clinical features, could provide new diagnostic tools and facilitate adequate choices of therapeutic interventions for selected patients suffering from CRS. The aim of present study was the assessment of macrophages in the polyp tissue and monocytes in the peripheral blood in the course of CRSwNP, and their functional immunophenotype. We analyzed 31 patients with CRSwNP. Nasal mucosa tissue was obtained via functional endoscopic sinus surgery (FESS). The control group included 10 patients with deviated nasal septum (DNS). Fluorochrome stained cells were proceed to acquisition using FACS Canto flow cytometer, and the results were analyzed using the software FACS Diva. In our study, we observed a significantly higher level of CD80, CD274, CD273 and TLR1 in nasal polyps compared to blood samples from patients with CRSwNP. This finding may suggest the importance of the PD-1 pathway as a therapeutic target in CRS and an important role for TLR1 in nasal polyp formation and maintenance. Our results may provide some insight into potential future targets of recurrent nasal polyp treatment and contribute to a better understanding of the inflammatory process in Chronic Rhinosinusitis.

RESUMO

OBJECTIVE: The main goal was to compare the clinical data of patients with T1 and T2 glottic cancer treated with CO2 transoral laser microlaryngoscopy (TLM) in the Tertiary Referral University Department of Otolaryngology, Head Neck Surgery, Poznan and the local Department of Otolaryngology, Oncology and Maxillofacial Surgery, Bydgoszcz. MATERIAL AND METHODS: Unified databases for the 7-year period January 2005-December 2011 were created to compare these two cohorts. The database contained 341 patients: 231 from the tertiary center and 110 from the local department, of which 298 (87%) were men, and 43 (13%) were women. RESULTS: Cordectomy type I-IV was performed in 250 (73%) patients, cordectomy type V-VI in 84 (25%) patients, and cordectomy enlarged to epiglottic petiole in 7 (2%) patients. Local recurrence was observed in 96 (28%) cases. Among these cases, 81 (87.5%) patients had salvage surgery: 43 re-cordectomy, 10 open partial laryngectomy, and 28 total laryngectomy. The outcomes for the whole cohort, Tertiary Referral Center and Local Department respectively were as follows: larynx preservation rate was 91.8%, 93.6%, and 88%; 3-year disease specific survival was 97.4%, 97.9%, and 93.3%; 3-year overall survival was 93.5%, 96.6%, and 85.5%; 5-year disease specific survival was 95.2%, 95.2%, and 96.3%; and 5-year overall survival was 84.5%, 88.7%, and 76%, respectively. CONCLUSION: Comparison of the cohorts showed that outcomes of primary treatment were similar but there were noticeable differences in salvage treatment efficacy, favoring patients from the Tertiary Referral Center.

RESUMO

Our goal was to describe a laryngeal-preserving single-stage procedure for the treatment of low-grade chondrosarcomas of the larynx: a total cricoidectomy with medial femoral condyle flap reconstruction. The study was designed as a case series of three consecutive patients with low-grade chondrosarcomas of the cricoid cartilage lamina, diameter 4.4, 5.2, 3.8 cm, respectively, who underwent total cricoidectomy in 2012. Single-staged reconstruction of the defect with medial femoral condyle flap including the periosteum and thin underlying cortical layer of the bone was conducted. Oncologic and functional results were observed during 3 years of follow-up. No evidence of tumor recurrence was detected during follow-up. One month after surgery, all patients were able to tolerate a soft diet and to speak satisfactorily. None of the patients reported aspiration after surgery nor experienced aspiration-related problems, which was confirmed by means of the Leipzig-Pearson scale. The speech ability was good, maximum phonation time was 14, 18, 21 s, respectively, and the voice handicap index scores ranged from 24 to 36 and had improved noticeably at 1, 3 and 6 months follow-up. Two patients were ultimately decannulated, and one female still has a tracheostomy; however, she is able to keep the tracheostoma closed for most of the time, maintaining good phonatory and swallowing functions. Total cricoidectomy with reconstruction by means of medial femoral condyle flap may replace the total laryngectomy in large low-grade chondrosarcomas of the cricoid cartilage.

RESUMO

The larynx is a complicated organ with very important functions. Reconstructive operations of the larynx often result in some function reduction caused by scars and stenoses. The aim of this report is to present the results of the one-stage reconstructive operation after a large excision of the chondrosarcoma of the larynx. The patient was male, aged 48 with the history of the operation of the highly mature cartilaginous sarcoma of the thyroid on the right side with tumor recurrence. The one-stage reconstructive surgery using medial condyle femur corticoperiosteal free flap which reshaped the cartilage scaffold and restored an inner layer as the mucosa was made. The flap survived without local and systemic complications. Six months follow-up revealed no local recurrence and good breathing results. There was no restriction of movement of the lower limbs. The patient returned to work previously performed. Results were shown in endoscopic examinations and computer tomography. The medial condyle femur corticoperiosteal free flap may be an option for reconstruction of large laryngeal defect with restoring its shape and inner layers.

RESUMO

Limited defects in the oral cavity can be treated with local and pedicled cheek flaps. It allows to preserve the functions of the resected organ. Large defects in the midline of the hard palate can be reconstructed with double opposing myomucosal cheek flaps. The aim of this study was to discuss the methodology of the flap harvest and to show our experiences of treatment in a group of 15 patients with oral cavity cancer. In 1 patient the double opposing myomucosal cheek flap was harvested due to the wider local defect. The small size of the flap with ability to use the double opposing cheek flap in more extended defects as well as short duration of the surgery procedure can lead to reduced risk of postoperative complications. Finally, cheek flaps form an effective method of treatment of defects in the oral cavity.

RESUMO

The aim of the study was to analyze the efficacy of treatment of closure of cutaneopharyngeal fistulas, following total laryngectomy, using a fasciocutaneous flap. In the group of 6 patients treated in years 2013-2014, in 4 (67%) patients the healing process was successful, in one patient complete flap necrosis was noted on the 6th day, in another patient a small cutaneopharyngeal fistula was recognized, which closed secondarily with no intervention. Flaps of this type, having a small risk of local complications at donor site and satisfactory functional and aesthetic results, may be an alternative form of flap to others used in the reconstruction of superficial deficits in the head and neck areas.

RESUMO

AIM OF THE STUDY: Aim of the study was to assess the results of surgical treatment of cervical recurrences in patients with thyroid cancer. MATERIAL AND METHODS: We assessed 66 reoperations of thyroid cancer recurrences in 51 patients. Reoperative surgeries covered I-VII neck levels. RESULTS AND CONCLUSIONS: The localization of cervical recurrence and the number of removed nodes did not depend on the type of thyroid cancer. Metastatic spread was predominantly observed in the central neck. Bilateral changes tended to be observed more often in younger patients (p = 0.07). Radical neck dissections were performed more often at younger age (p < 0.01). Postoperative vocal cord paresis was noted in 13 patients; in 5 permanent tracheotomy was necessary, and 2 underwent laser glottis procedures (posterior cordectomies). Two patients died in the postoperative period - 1 due to chylothorax and 1 due to severe bleeding from the common carotid artery.

RESUMO

BACKGROUND AND PURPOSE: The object of the study was to present our own experience in the management of cervical oesophageal and hypopharyngeal perforations after anterior cervical spine surgery. MATERIAL AND METHODS: The study group consists of 5 patients treated in Department of Otolaryngology Poznan University of Medical Sciences in 2009-2011. Different materials and techniques were used to repair the perforations: infrahyoid flap, primary sutures supported by sternocleidomastoid muscle flap, thigh flap and forearm flap in two cases. RESULTS: Four out of 5 patients were referred to our department in a poor general condition, with infected neck fistulas, three patients after prolonged conservative treatment, and three patients after initial attempts to repair the perforation outside our institution. One-stage reconstructive surgery was successful in three cases, while in two others secondary interventions were necessary. Total hospital stay ranged in the analysed group from 23 to 191 days, hospital stay in our department from 1 to 62 days, hospital stay from the final procedure from 18 to 26 days. Swallowing function was within normal limits in all cases 12-14 days after the surgery. CONCLUSIONS: The authors' experience shows that in long-lasting and infected cervical oesophageal and hypopharyngeal perforations following anterior cervical spine surgery distant flaps should be primarily used as a source of a well-vascularized and unchanged tissue. It seems to be crucial to repair the perforations immediately after the first symptoms appear - such an approach significantly reduces total hospital stay and improves the prognosis.

RESUMO

OBJECTIVE: Evaluation the outcome after extensive surgery of salivary glands tumors with simultaneous reconstruction of soft tissue and skin defect. MATERIAL: In the period 2007-2011, surgery treatments performed in 295 of major salivary glands. 31 patients underwent surgery due to malignant parotid gland tumors: 19 women (61%) and 12 men (39%). In 8 (26%) presented skin infiltration. 10 (32%) patients had facial palsy between II-IV degree (House Brackmann scale). The radiographic findings in some patients showed infiltration of the deep lobe of parotid gland, external auditory canal, infiltration of mastoid process, skull base and the subtemporal fossa. METHODS: Of the 31 patients in 13 (42%) reconstruction techniques with muscle cutaneous trapezius flap were applied in 4 (31%) patients. In group of 7 (54%) patients using a muscle flap based on the sterno-cleido-gland, in 2 (15%) patients defects were covered using the free anterior lateral thigh flap. RESULTS: In all patients, healing proceeded normally. In the operated patients, one patient did not receive radical surgery due to the infiltration of the skull base. Length of hospitalization ranged between 7-21 days. In no case was lost flap, also there was no local complications at the donor. CONCLUSIONS: The choice of treatment for malignant parotid gland tumors which are usually radioresistant is surgical resection. In patients with extensive tumors with infiltration of neighbouring organs reconstruction with use of distant flaps are recommended. It provides a good oncological and aesthetic result.
