Cochlear implant cost analysis in adults: a European narrative review.

PURPOSE: The aim of this study was to provide an updated European narrative review spanning the last decade, focusing on the cost-effectiveness of cochlear implants (CIs) for adults with severe to profound post-lingual hearing loss. METHODS: This review encompasses both prospective and retrospective approaches, as well as cross-sectional and longitudinal trials conducted on CIs in adults. All studies related to European countries (Austria, Germany, Switzerland, the Netherlands, Sweden, the UK and Poland) were conducted in English and were published between 2012 and June 2023. RESULTS: Nine studies were included in the analysis. The patients' ages ranged from 18 years to over 67 years, with sample sizes ranging from 20 to 100 patients; two of these studies were focused on single-sided deafness in adults. The Markov model was identified as the most commonly utilized analysis method. CONCLUSIONS: This review identified a general consensus on CI cost-effectiveness, despite substantial variability among countries in factors such as observation time horizons, cost-effectiveness thresholds, methods of cost collection, discount rates, CI eligibility criteria and country-specific health systems. Generally, CIs yield positive societal benefits for working-age individuals, potentially less for seniors. Early unilateral CI enhances cost-effectiveness, highlighting the importance of prompt candidate identification. A consistent undersupply of CIs relative to the percentage of potential recipients emerged across countries. Therefore, further investigation into subcategories such as single-sided deafness is warranted, along with country-specific cost analyses. Emphasizing the significance of detailed information on health systems and associated costs and benefits is crucial for facilitating comparisons across different settings.

Otological Planning Software-OTOPLAN: A Narrative Literature Review.

The cochlear implant (CI) is a widely accepted option in patients with severe to profound hearing loss receiving limited benefit from traditional hearing aids. CI surgery uses a default setting for frequency allocation aiming to reproduce tonotopicity, thus mimicking the normal cochlea. One emerging instrument that may substantially help the surgeon before, during, and after the surgery is a surgical planning software product developed in collaboration by CASCINATION AG (Bern, Switzerland) and MED-EL (Innsbruck Austria). The aim of this narrative review is to present an overview of the main features of this otological planning software, called OTOPLAN®. The literature was searched on the PubMed and Web of Science databases. The search terms used were "OTOPLAN", "cochlear planning software" "three-dimensional imaging", "3D segmentation", and "cochlear implant" combined into different queries. This strategy yielded 52 publications, and a total of 31 studies were included. The review of the literature revealed that OTOPLAN is a useful tool for otologists and audiologists as it improves preoperative surgical planning both in adults and in children, guides the intraoperative procedure and allows postoperative evaluation of the CI.

COVID-19 and Deafness: Impact of Face Masks on Speech Perception.

BACKGROUND: The COVID-19 pandemic has made wearing face masks a common habit in public places. Several reports have underlined the increased difficulties encountered by deaf people in speech comprehension, resulting in a higher risk of social isolation and psychological distress. PURPOSE: To address the detrimental effect of different types of face masks on speech perception, according to the listener hearing level and background noise. RESEARCH DESIGN: Quasi-experimental cross-sectional study. STUDY SAMPLE: Thirty patients were assessed: 16 with normal hearing [NH], and 14 hearing-impaired [HI] with moderate hearing loss. DATA COLLECTION AND ANALYSIS: A speech perception test (TAUV) was administered by an operator trained to speak at 65 dB, without a face mask, with a surgical mask, and with a KN95/FFP2 face mask, in a quiet and in a noisy environment (cocktail party noise, 55 dB). The Hearing Handicap Index for Adults (HHI-A) was administered twice, asking subjects to complete it for the period before and after the pandemic outburst. A 2-way repeated-measure analysis of variance was performed. RESULTS: The NH group showed a significant difference between the no-mask and the KN95/FFP2-mask condition in noise (p = 0.01). The HI group showed significant differences for surgical or KN95/FFP2 mask compared with no-mask, and for KN95/FFP2 compared with surgical mask, in quiet and in noise (p < 0.001). An increase in HHI-A scores was recorded for the HI patients (p < 0.001). CONCLUSION: Face masks have a detrimental effect on speech perception especially for HI patients, potentially worsening their hearing-related quality of life.

The CO2 waveguide laser with flexible fiber in transoral resection of oral and oropharyngeal cancers: a retrospective cohort study on postoperative and quality of life outcomes.

The aim of this study was to evaluate the CO2 waveguide laser (WG CO2 laser) with flexible fiber (Lumenis Ltd., Yokneam, Israel) in the treatment of oral and oropharyngeal cancers, specifically focusing on postoperative outcomes, pain, and quality of life (QoL). Eighty-one patients, 43 women and 38 men, with oral or oropharyngeal cancer who consecutively underwent transoral resection by WG CO2 laser from August 2015 to April 2020 were retrospectively enrolled. Resections were performed in super pulsed mode with a power setting ranging between 3 and 10 W. Data about frozen sections, reconstruction, complication rate, length of hospital stay, tracheostomy rate and time to decannulation, nasogastric feeding tube rate and time to oral feeding, pain, and QoL were reviewed. Continuous variables were presented as mean and standard deviation. Concordance between intraoperative frozen section examination and definitive histology was calculated using Cohen's K test of agreement. The mean length of hospital stay was 13 days. The feeding tube rate was 81%; the tracheostomy rate was 35%; the feeding tube was left in place for 8 days on average, and the time to decannulation was 9 days. The only complication was a postoperative bleeding in 4 patients. The median postoperative pain score measured by the Numeric Pain Rating Scale on postoperative days 1, 3, and 5 was 0 and there was a constant decrease in painkiller use over the days. The overall mean composite QoL score was 77 ± 14, with excellent results in saliva, taste, pain, and speech domains. Frozen section evaluation had a specificity of 99% and a negative predictive value of 98%. WG CO2 laser is a good and safe tool for transoral tailored resection of oral and oropharyngeal cancers. It ensures a good overall QoL and guarantees fast recovery and a very low postoperative pain.

Cochlear Implant Surgery: How to Fix Receiver/Stimulator Avoiding Extrusion.

Cochlear implant (CI) surgery is generally safe and associated with a limited number of complications, among which the extrusion of the receiver/stimulator (R/S) or the electrode misplacement and migration might require a CI re-implantation. The aim of this pilot study is to describe a new technique to firmly fix the R/S using the Mitek suture anchors system (Depuy Mitek Surgical Products, Inc. Raynham, Massachusetts). We tested two different models and in our experience, the web of suture created with this device can improve the stability of the bond of the R/S to the underlying curved bone surface. So, this system resulted in a less laborious manner keeping low the complication rate.

Surgical resection of oral cancer: en-bloc versus discontinuous approach.

OBJECTIVES: In the past literature agreed on treating oral carcinomas, using an "en-bloc" resection (EBR) but recently minimally invasive transoral surgery has spread as the preferable treatment for selected cases. This latter technique, which is performed with a discontinuous resection (DR), allows for a satisfactory postoperative quality of life (QoL) maintaining good survival rates. MATERIALS AND METHODS: In this study, we analyzed data about 147 surgically treated patients with oral cancer involving tongue and floor of the mouth. The sample was divided according to the surgical approach: EBR and DR group which were compared in terms of recurrence, overall survival, disease-free survival, and QoL. RESULTS: In the DR group, survival analysis showed better results in term of survival, locoregional control, and postoperative anxiety, while the other QoL scores were similar in the two groups. CONCLUSION: The more invasive approach does not correlate to a better outcome. In selected cases, DR is an oncologically safe technique; EBR is still a valid option to treat advanced oral cancers.

Topical Steroids in Rhinosinusitis and Intraoperative Bleeding: More Harm Than Good?

The aim of this study was to assess whether the chronic preoperative administration of intranasal corticosteroids (INCs) in chronic rhinosinusitis with/without nasal polyposis (CRSwNP/CRSsNP, respectively) could significantly influence bleeding during functional endoscopic sinus surgery (FESS). We prospectively enrolled 109 patients (56 CRSwNP and 53 CRSsNP) candidate for FESS who underwent clinical evaluation and anamnestic data collection. They were allocated to 2 groups depending on whether or not they were chronic INC users, as declared at their first medical evaluation: chronic "INC users" represented the treated group, while "INC nonusers" formed the control group. Lund-Mackay and American Society of Anesthesiology (ASA) scores, blood loss expressed both in milliliters and using the Boezaart scale, operation time in minutes, pre- and postoperative 22-item Sino Nasal Outcome Scores (SNOT-22) were collected. Each sample underwent histopathological evaluation. The results showed that anamnestic information, Lund-Mackay, and SNOT-22 scores were similar between the 2 groups (P > .05). The average blood loss expressed in milliliters and operative time were slightly, but not significantly, higher in the INC user group, while the Boezaart scores proved significantly higher in the INC users (P = .038). No differences emerged between CRSwNP and CRSsNP within each group in terms of bleeding. The pathologist described common features in the majority (78%) of INC group samples: ectatic venules embedded in a fibrous stroma and hypertrophy of the arterial muscular layer. In our experience, despite the presence of NP, chronic preoperative administration of INCs was associated with increased intraoperative bleeding according the Boezaart scale although objective recordings of blood loss were not statistically different between the INC users and nonusers.

Frozen sections and complete resection in oral cancer surgery.

OBJECTIVES: Although the reliability of frozen sections for the intraoperative assessment of complete tumour excision has been established, the best location for collection and the impact of the type of sampling are still debated. We retrospectively investigated the reliability of frozen sections when collected from the surgical bed as tissue strips representative of the whole superficial margin and as a bowl of tissue underlying the resection site for deep margin, and the possibility of relying on frozen section negativity to consider resections complete. MATERIALS AND METHODS: Frozen section reliability was calculated by comparing histology before and after formalin embedding and then categorised by sampling type, in 182 patients undergoing transoral resection of oral cancer. RESULTS: Comparing frozen and permanent histology, sensitivity, specificity and accuracy were 69%, 98% and 96%, respectively; categorisation by sampling type failed to produce statistically significant differences. Based on frozen section negativity after formalin embedding, complete resections were obtained in 91.7% of patients with multiple-strip and bowl frozen sections. CONCLUSION: Frozen sections collected as tissue strips and bowl are as reliable as point sampling in the intraoperative guidance of surgical resections. They effectively provide for margin enlargement, thereby increasing the surgeon's confidence that negative margins are clear.

Is there a role for ultrasonic surgery in transoral laryngeal cancer resections?

INTRODUCTION: Minimally invasive surgery for laryngeal cancer is nowadays the goal of all larynx surgeons. Transoral laser microsurgery is a widespread and standardized technique that has made it possible to reduce surgical morbidities and hospitalization and to spare laryngeal function. Nonetheless, it has some limitations, which may be exceeded by using new optical and cutting devices as in TransOral UltraSonic Surgery. Areas covered: The aim of this paper is to identify current knowledge about ultrasonic scalpel (US) application in transoral laryngeal surgery and to deduce reasonable indications and contraindications of the tool. Expert opinion: Transoral laryngeal surgery with US is feasible and allows for 'angulated' dissections with higher hemostatic capacity than the CO2 laser. When coupled with an endoscope, surgeons have the possibility to angulate the laryngeal exposure from the inside, reducing blind areas. Nonetheless, US blades are quite bulky, thermal damage is higher than that produced by CO2 laser, and its use should be avoided where the functional result is more closely related to the amount of resected tissue. Tumors limited to the suprahyoid larynx are the current indications for US surgery.

Perimarginal lymph nodes: an undervalued entity in oral cancer.

PURPOSE: In a previous study, we gave a surgical description of a group of lymph nodes in the submandibular area at risk of remaining undissected during neck dissection (ND) for which we have proposed the term "perimarginal nodes" (PMNs) due to their proximity to marginal mandibular nerve (MMN). The aim of this study is to evaluate prevalence of PMNs involvement in oral cavity squamous cell cancer (OCSCC) and to verify if metastases are related to primary tumor characteristics or to the state of the neck. METHODS: We recruited a total of 39 consecutive patients diagnosed with OCSCC candidate to ND. Histological characteristics of PMNs were analyzed and the incidence of metastases in relation to the primary tumor characteristics were noted. RESULTS: PMNs were found to be involved with metastases in 8 patients (20.5%). No characteristic of the primary tumor seems to influence the metastatic involvement of the PMNs. CONCLUSIONS: PMNs represent a frequent site of micro-metastases in patients diagnosed with OCSCC regardless of other characteristics of the primary tumor.

Intraoperative Margin Control in Transoral Approach for Oral and Oropharyngeal Cancer.

OBJECTIVES: Piecemeal resection provides an innovative conceptual tool for margins surveillance because it entails the intraoperative evaluation of the whole resection margins and not just sample points, which should result in a better control of deep margins compared to en bloc resection. Although it is recognized that the intraoperative use of narrow band imaging (NBI) results in a better control of superficial margins, in this exploratory study we investigated whether NBI and piecemeal resection could be used in combination to improve margin control at both superficial and deep levels. Because piecemeal resection is based on frozen section analysis, we wanted to verify its reliability compared to definitive histological examination. METHODS: The status of resection margins in a group of patients with oral and oropharyngeal cancers treated with NBI and laser CO2 piecemeal resection (group 1) was compared with that of an historical group of patients (group 2) treated with NBI and conventional en bloc resection. In group 1, sensitivity, specificity, and positive and negative predictive values were used to verify the rate of concordance between frozen section and definitive histology. RESULTS: The difference between deep positive margins in the two groups was statistically significant (P = 0.042). The high sensitivity and specificity (94.6% and 94.7%, respectively) of frozen section analysis also demonstrated its reliability in the examination of larger samples corresponding to the whole margin. CONCLUSION: Even if our findings are limited by the small number of patients, we are confident that the combined use of NBI and piecemeal resection could represent an attractive surgical strategy to improve margin control.

Predicting laryngeal exposure in microlaryngoscopy: External validation of the laryngoscore.

OBJECTIVES: Optimal laryngeal exposure during transoral laryngeal surgery is fundamental. We aimed to evaluate the reliability of a recently proposed score (Laryngoscore) in predicting difficult laryngeal exposure (DLE) in an independent cohort of patients undergoing elective microlaryngoscopy. We also verified the relation between DLE, surgeon's expertise, and difficult intubation, and investigated possible areas for score improvement. STUDY DESIGN: Prospective validation study. METHODS: A total of 136 patients were preoperatively evaluated using the Laryngoscore. Patients were divided into three classes according to patient position, type of laryngoscope, and need for external counterpressure to expose the anterior commissure. Based on their mean scores, two groups were identified: good laryngeal exposure (GLE) and DLE. A receiver operating characteristic curve with the Youden index was used to calculate the optimal cutoff value. The χ2 and Fisher exact test were used to correlate GLE and DLE to the surgeon's expertise and difficult intubation. The intraoperative anatomical parameters underlying DLE were also recorded. RESULTS: The optimal cutoff value for differentiating GLE and DLE was 4, which identified 80.6% of DLE cases. No statistically significant difference in GLE and DLE distribution was found between surgeons (P = 0.43). The correlation between difficult intubation and DLE was statistically significant (P = 0.03). The intraoperative parameters determining DLE were epiglottis characteristics (floppy, tight, or short), bulky abdomen and chest, bulky tongue base, mobile teeth, and a narrow laryngeal aditus. CONCLUSION: The Laryngoscore is reliable for detecting DLE preoperatively. The inclusion of additional parameters may allow a more complete assessment and maximize its diagnostic accuracy.

Prognostic indicators of improved survival and quality of life in surgically treated oral cancer.

OBJECTIVE: No published study has analyzed the prognostic factors of surgically treated oral squamous cell carcinoma (OSCC) in relation to both survival and quality of life (QoL). The aim of this study was to analyze postoperative QoL in relation to survival to identify which parameters can predict the long-term outcome allowing the best QoL. STUDY DESIGN: This retrospective cohort study considered 167 patients affected by OSCC treated surgically at the Otolaryngology Department of Cattinara Hospital (Trieste, Italy) by a single surgeon. We collected data about the main prognostic factors and the postoperative QoL 12 month after surgery. RESULTS: The 5-year overall survival rate was equal to 68.1%, and the 5-year disease-specific survival was 77.8%. In this sample, 32% of patients also underwent adjuvant chemoradiotherapy. On stepwise Cox regression, the best predictors of disease-specific survival were the N stage (P < .001) and tumor depth of invasion (P < .001). QoL was affected by N stage, depth of invasion, invasive surgical approach, radiotherapy, and neck dissection (P < .05). CONCLUSION: The prognostic factors that affect both survival rates and residual QoL are the surgical approach, the neck stage, and the depth of invasion, all of which can be minimized by early diagnosis.

Intraoperative monitoring of marginal mandibular nerve during neck dissection.

BACKGROUND: The purpose of this study was to assess the efficacy of intraoperative nerve integrity monitoring (NIM) to prevent marginal mandibular nerve injuries during neck dissection. METHODS: This prospective study compared 36 patients undergoing NIM-assisted neck dissection from July 2014 to March 2015 to a cohort of 35 patients subjected to neck dissection over an identical period of time before the technique was introduced. We also assessed possible correlations between marginal mandibular nerve injuries and other factors, such as anthropometric measurements, presence of clinical neck metastases, type of neck dissection, and site of primary tumor. RESULTS: The incidence of marginal mandibular nerve paralyses was significantly lower among the group of patients undergoing NIM-assisted neck dissection (P = .021). There was no significant difference in the duration of the procedure, and the technique resulted in a limited increase of cost. No other factor seemed to influence the onset of marginal mandibular nerve palsy. CONCLUSION: In our opinion, NIM is a valuable aid for preventing marginal mandibular nerve injuries during neck dissection.

Tailored resections in oral and oropharyngeal cancer using narrow band imaging.

PURPOSE: In a previous pilot study we observed that intra-operative narrow-band imaging (NBI) helps achieve clear superficial resection margins. The aim of this study was to verify if the use of intra-operative NBI can help to obtain tailored resections and if it is influenced by the lesion site, aspects not investigated in our previous study. MATERIALS AND METHODS: The resection margins of 39 oral and 22 oropharyngeal squamous cell carcinomas were first set at 1.5cm from the macroscopic lesion boundary (white light, WL, tattoo). Then, the superficial tumor extension was more precisely defined with NBI, giving rise to three possible situations: NBI tattoo larger than the WL tattoo, NBI tattoo coinciding with the WL tattoo, or NBI tattoo smaller than the WL tattoo. For each of these situations the space comprised between the NBI and WL tattoos was defined "NBI positive", "NBI null", and "NBI negative", respectively. Resections were performed following the outer tattoo. The number of clear superficial resection margins, and the pathological response on the "NBI-positive" and the "NBI-negative" areas were recorded. RESULTS: We obtained 80.3% negative superficial resection margins. NBI provided a more precise definition of superficial tumor extension in 43 patients. Sensitivity, specificity, positive and negative predictive values were 94.4%, 64%, 79.1% and 88.9%, respectively; a test of proportions demonstrated they were not influenced by tumor site. CONCLUSIONS: NBI could allow for real-time definition of superficial tumor extension with possible tailored resections and fewer positive superficial resection margins; it is not influenced by tumor site.

Hyaluronate effect on bacterial biofilm in ENT district infections: a review.

Bacterial resistance is a growing phenomenon which led the scientific community to search for new therapeutic targets, such as biofilm. A bacterial biofilm is a surface-associated agglomerate of microorganisms embedded in a self-produced extracellular polymeric matrix made of polysaccharides, nucleic acids, and proteins. Scientific literature offers several reports on a biofilm's role in infections regarding various body districts. The presence of a bacterial biofilm is responsible for poor efficacy of antibiotic therapies along with bacterial infections in ear, nose, and throat (ENT) districts such as the oral cavity, ear, nasal cavities, and nasal sinuses. In particular, bacterial biofilms are associated with recalcitrant and symptomatically more severe forms of chronic rhinosinusitis. As of today, there are no therapeutic options for the eradication of bacterial biofilm in ENT districts. Hyaluronic acid is a glycosaminoglycan composed of glucuronic acid and N-acetylglucosamine disaccharide units. Its efficacy in treating rhinosinusitis, whether or not associated with polyposis, is well documented, as well as results from its effects on mucociliary clearance, free radical production and mucosal repair. This review's aim is to evaluate the role of bacterial biofilms and the action exerted on it by hyaluronic acid in ENT pathology, with particular attention to the rhinosinusal district. In conclusion, this paper underlines how the efficacy of hyaluronate as an anti-bacterial biofilm agent is well demonstrated by in vitro studies; it is, however, only preliminarily demonstrated by clinical studies.

Follow-up of oral and oropharyngeal cancer using narrow-band imaging and high-definition television with rigid endoscope to obtain an early diagnosis of second primary tumors: a prospective study.

Narrow-band imaging (NBI) is an optical technique enhancing mucosal vasculature. The aim of this study is to assess the effectiveness of rigid NBI endoscopy in the early detection of second primaries or local recurrences after treatment for oral (OSCC) and oropharyngeal squamous cell carcinoma (OPSCC), its advantage over standard white-light (WL) endoscopy, and the influence of previous radiotherapy, the learning curve, and lesion site. Between January 2013 and June 2015, 195 patients treated for OSCC or OPSCC with surgery alone (group A) or radiotherapy with or without surgery and/or chemotherapy (group B) underwent additional follow-up assessments using NBI. Sensitivity, specificity, positive/negative predictive values (PPV and NPV), and accuracy for detecting second primaries or local recurrences were calculated for patients with at least two NBI assessments. The effect of previous radiotherapy was determined by test of proportions and that of the learning curve and lesion site with Fisher's exact test. 138/195 patients were included in the analysis. NBI sensitivity, specificity, PPV, NPV, and accuracy for groups A and B were 89.5 vs 100%, 85.2 vs 81.5%, 65.4 vs 69.7%, 96.3 vs 100%, and 86.3 vs 87%, respectively. The diagnostic gain of NBI was 88.2% in group A and 69.6% in group B. The learning curve was the main source of false positives (p = 0.025), whereas radiotherapy and lesion site were uninfluential (p = NS). NBI appears useful for follow-up after treatment for OSCC or OPSCC, its performance being affected only by the learning curve and not by previous treatment or lesion site.

Repeated canalith repositioning procedure in BPPV: Effects on recurrence and dizziness prevention.

PURPOSE: To evaluate whether a repeated canalith repositioning procedure (CRP) influences the residual symptoms and the rate of recurrence of benign paroxysmal positional vertigo (BPPV) in patients with post-CRP dizziness. MATERIALS AND METHODS: In this retrospective study, we analyzed 292 patients at the referral center for ENT diseases with a first episode of BPPV treated with a single CRP following clinical practice guidelines. In 178 patients (67.9%) who presented dizziness after BPPV recovery at the follow-up visit, 94 patients underwent CRP (treated group) and 84 did not (non-treated group). A subjective evaluation of vertigo was made by way of a questionnaire. The rates of recurrence of BPPV and residual dizziness were statistically compared between the treated and the non-treated groups; survival analysis was carried out as well. RESULTS: In an observational period ranging from 1 to 6years, BPPV recurred in 122 subjects (46.6%) of the investigated population. Among the patients with residual dizziness, the difference in rate of recurrence of BPPV between the treated group and the non-treated group was not statistically significant (p=0.84). The treated group presented a significantly higher rate of recovery from dizziness compared to the non-treated group (p<0.001). CONCLUSIONS: A repeated CRP in patients with post-CRP dizziness increased the rate of recovery from dizziness but had no influence on BBPV recurrence.

NBI utility in the pre-operative and intra-operative assessment of oral cavity and oropharyngeal carcinoma.

PURPOSE: Despite advances in the surgical management of head and neck squamous cell carcinoma, the identification of synchronous lesions, precancerous lesions around the main tumor, or the unknown primary in the case of neck metastasis remains a problem, as these lesions may be invisible to the naked eye or with standard white light (WL) endoscopy. However, the advent of tools such as narrow-band imaging (NBI) could help the clinician. The purpose of this study was to assess the impact of NBI during the pre-operative and intra-operative stages of management of oral and oropharyngeal cancers. MATERIALS AND METHODS: NBI was used pre-operatively in 47 patients with oral or oropharyngeal squamous cell carcinoma to identify the involvement of adjacent subsites, multifocality, synchronous lesions or an unknown primary. NBI was used intra-operatively in 30 patients to better define the tumor limits and guide the resection. The advantage of NBI versus WL endoscopy was analyzed by calculating the true and false positive rate pre-operatively, and the need for resection enlargements, histology of the enlargement, and the rate of clear margins at definitive histology, intra-operatively. RESULTS: Pre-operatively, the diagnostic gain of NBI was 8.5%, allowing identification of three synchronous tumors and one unknown primary. Intra-operatively, NBI improved the definition of tumor limits in 67.7% of cases, with resection enlargements showing dysplasia and carcinoma in 8 and 12 patients, respectively; we obtained 74.2% negative margins at histology. CONCLUSIONS: NBI could represent an added value in the pre-operative and intra-operative assessment of oral cavity and oropharyngeal carcinoma.

Diagnostic and therapeutic features associated with modification of quality-of-life's outcomes between one and six months after major surgery for head and neck cancer / Características terapêuticas e diagnósticas associadas a modificações nos resultados da qualidade de vida entre um e seis meses após cirurgia de grande porte para câncer de cabeça e pescoço

ABSTRACT INTRODUCTION: Treatments used in head and neck cancer greatly impact the physical, psychological and functional state of patients. Evaluation of quality of life has become an integral part of the treatment. OBJECTIVE: This retrospective study evaluates features involved in changes in quality of life after major surgery for head and neck cancer within six months, according to self-reported outcomes. METHODS: One hundred and thirty patients completed the University of Washington Quality of Life questionnaire one and six months after major surgery for head and neck cancer. A multivariate model was used to evaluate which diagnostic and therapeutic features were related to improvement of quality of life within a six-month period. RESULTS: Significant improvement in most features related to quality of life was already recognizable at six months. Patients submitted to more invasive treatment had the biggest improvement in quality of life between time-points, as well as those patients with bigger tumors. CONCLUSION: After major surgery, patients may undergo fast recovery, with overall quality of life likely to improve in the short-term. Clinicians must be aware of the importance of dealing with treatment-related issues immediately after surgery, with hopeful possibility of on-the-upgrade results.
