RESUMO
PURPOSE: Middle turbinate (MT) surgery is extremely common during endoscopic sinus surgery procedures, though no agreement exists on which techniques provide the best outcomes. This PRISMA-compliant systematic review aims to assess which MT surgery technique yields the least postoperative adverse effects and the best objective and subjective outcomes. METHODS: A comprehensive search criteria was conducted in multiple databases up to July 3, 2023, to identify studies reporting surgical treatments of the MT. After screening and quality assessment, 14 articles were included for analysis. Data on patients demographics, surgical approaches, postoperative treatment and follow-up, objective and subjective outcomes were extracted and reviewed. RESULTS: Out of 173 unique papers identified, 14 articles met the inclusion criteria, predominantly randomized controlled trials (n = 9). Antero-inferior middle turbinectomy was the predominant surgical approach. Most studies evaluated results with postoperative endoscopy, a superior outcome was documented in the intervention group (ten out of eleven cases). In four out five studies using the SNOT-22, the treatment group was associated with a statistically significant improvement. Olfactory questionnaires highlighted superior olfactory outcome in two out of three studies. The UPSIT score revealed no significant difference between groups. Objective olfactory assessments favored treatment groups in both studies utilizing olfactometry. CONCLUSIONS: It seems that a partial MT surgical approach consistently yields subjective and objective improvements compared to conservative measures, also suggesting a positive impact on smell function. Despite it appears that better outcomes with fewer complications are consistently achieved with partial techniques, it remains challenging identifying which partial technique surpasses the others, due to significant heterogeneity among the studies.
RESUMO
PURPOSE: This study aimed to evaluate the utility of large language model (LLM) artificial intelligence tools, Chat Generative Pre-Trained Transformer (ChatGPT) versions 3.5 and 4, in managing complex otolaryngological clinical scenarios, specifically for the multidisciplinary management of odontogenic sinusitis (ODS). METHODS: A prospective, structured multidisciplinary specialist evaluation was conducted using five ad hoc designed ODS-related clinical scenarios. LLM responses to these scenarios were critically reviewed by a multidisciplinary panel of eight specialist evaluators (2 ODS experts, 2 rhinologists, 2 general otolaryngologists, and 2 maxillofacial surgeons). Based on the level of disagreement from panel members, a Total Disagreement Score (TDS) was calculated for each LLM response, and TDS comparisons were made between ChatGPT3.5 and ChatGPT4, as well as between different evaluators. RESULTS: While disagreement to some degree was demonstrated in 73/80 evaluator reviews of LLMs' responses, TDSs were significantly lower for ChatGPT4 compared to ChatGPT3.5. Highest TDSs were found in the case of complicated ODS with orbital abscess, presumably due to increased case complexity with dental, rhinologic, and orbital factors affecting diagnostic and therapeutic options. There were no statistically significant differences in TDSs between evaluators' specialties, though ODS experts and maxillofacial surgeons tended to assign higher TDSs. CONCLUSIONS: LLMs like ChatGPT, especially newer versions, showed potential for complimenting evidence-based clinical decision-making, but substantial disagreement was still demonstrated between LLMs and clinical specialists across most case examples, suggesting they are not yet optimal in aiding clinical management decisions. Future studies will be important to analyze LLMs' performance as they evolve over time.

PURPOSE: Sinonasal nuclear protein in testis carcinoma (SNUTC) is a rare, aggressive malignancy caused by genetic rearrangements in the NUTM1 gene. The prognosis of SNUTC ranks among the most unfavorable within the naso-sinusal district, with an overall survival of 9.7 months. This systematic review aimed to determine the best therapeutic strategy for SNUTC. METHODS: We reviewed eligible articles for patient demographics, TNM and stage at presentation, best response after primary treatment, disease-free survival and overall survival (OS) times, other following therapy lines, and final outcomes. RESULTS: Among 472 unique citations, 17 studies were considered eligible, with reported treatment data for 25 patients. Most studies (n = 12) were case reports. The most frequently administered treatment regimen was surgery as primary treatment and combined radiochemotherapy as second-line or adjuvant treatment. Four patients were alive at follow-up. CONCLUSION: Basing on the existing literature, a standardized line in the treatment of SNUTC is not yet well delineated. A self-personalized strategy of therapy should be drawn on each patient affected by SNUTC.

PURPOSE: Nowadays, several efficacious biologic drugs are used for severe asthma with or without chronic rhinosinusitis with nasal polyps (CRSwNP). However, it has been observed that not all comorbid patients (asthma/CRSwNP) receiving biologic treatment for asthma experience satisfactory control of both conditions equally. METHODS: We selected 20 patients who had both severe asthma and comorbid CRSwNP under biological treatment with benralizumab, omalizumab or mepolizumab with adequate control of asthma but inadequate control of nasal symptoms. Patients were switched to dupilumab and outcomes were evaluated at baseline (T0), at 3 months (T1), at 6 months (T2), at 12 months (T3) and finally at 18 months (T4). Data were collected at each time point including blood tests measuring eosinophil levels and total IgE, SNOT22, ACT, NPS score, rhinomanometry, olfactory testing, and nasal cytology. RESULTS: The results showed an overall improvement in all the outcomes. Peripheral eosinophilia was observed consistently with existing literature. All patients registered an improvement in sinonasal outcomes, while only one patient had a worsening of asthma. Three patients interrupted the therapy due to various causes: poor asthma control, onset of psoriasis and thrombocytopenia. CONCLUSIONS: The response to a biologic treatment for CRSwNP control may be heterogenous and it seems that patients may benefit from switching improving control in equal measure in the upper and lower airway. Further studies to explore the endotype/phenotype which best fits with each biologic are mandatory to personalize the therapy.

PURPOSE: This PRISMA-compliant systematic review aims to analyze the existing applications of artificial intelligence (AI), machine learning, and deep learning for rhinological purposes and compare works in terms of data pool size, AI systems, input and outputs, and model reliability. METHODS: MEDLINE, Embase, Web of Science, Cochrane Library, and ClinicalTrials.gov databases. Search criteria were designed to include all studies published until December 2021 presenting or employing AI for rhinological applications. We selected all original studies specifying AI models reliability. After duplicate removal, abstract and full-text selection, and quality assessment, we reviewed eligible articles for data pool size, AI tools used, input and outputs, and model reliability. RESULTS: Among 1378 unique citations, 39 studies were deemed eligible. Most studies (n = 29) were technical papers. Input included compiled data, verbal data, and 2D images, while outputs were in most cases dichotomous or selected among nominal classes. The most frequently employed AI tools were support vector machine for compiled data and convolutional neural network for 2D images. Model reliability was variable, but in most cases was reported to be between 80% and 100%. CONCLUSIONS: AI has vast potential in rhinology, but an inherent lack of accessible code sources does not allow for sharing results and advancing research without reconstructing models from scratch. While data pools do not necessarily represent a problem for model construction, presently available tools appear limited in allowing employment of raw clinical data, thus demanding immense interpretive work prior to the analytic process.

PURPOSE: This PRISMA-compliant systematic review aimed to assess risks and benefits of sirolimus treatment for paediatric lymphatic malformations by focusing not only on treatment efficacy but also on possible treatment-related adverse events, and treatment combinations with other techniques. METHODS: Search criteria were applied to MEDLINE, Embase, Web of Science, Scopus, Cochrane Library, and ClinicalTrials.gov databases and included all studies published up to March 2022 reporting paediatric lymphatic malformations treated with sirolimus. We selected all original studies that included treatment outcomes. After the removal of duplicates, selection of abstracts and full-text articles, and quality assessment, we reviewed eligible articles for patient demographics, lymphatic malformation type, size or stage, site, clinical response rates, sirolimus administration route and dose, related adverse events, follow-up time, and concurrent treatments. RESULTS: Among 153 unique citations, 19 studies were considered eligible, with reported treatment data for 97 paediatric patients. Most studies (n = 9) were case reports. Clinical response was described for 89 patients, in whom 94 mild-to-moderate adverse events were reported. The most frequently administered treatment regimen was oral sirolimus 0.8 mg/m2 twice a day, with the aim of achieving a blood concentration of 10-15 ng/mL. CONCLUSION: Despite promising results for sirolimus treatment in lymphatic malformation, the efficacy and safety profile of remains unclear due to the lack of high-quality studies. Systematic reporting of known side effects, especially in younger children, should assist clinicians in minimising treatment-associated risks. At the same time, we advocate for prospective multicentre studies with minimum reporting standards to facilitate improved candidate selection.

PURPOSE: Otitis media with effusion (OME), recurrent acute otitis media and conductive hearing loss (CHL) are significantly prevalent in children with cleft palate (CP) and cleft lip and palate (CLP). Rapid Maxillary Expansion (RME) appears to have a positive effect also on middle ear disorders in these patients. The study aims to offer a prospective evaluation of RME effects in a group of patients with CP/CLP in terms of OME, CHL. METHODS: A prospective observational study was conducted. Thirty-four CP, CLP and submucosa cleft patients who received orthodontic indication to RME treatment for OME or conductive hearing loss in a tertiary institutional Care Unit of San Paolo Hospital, Milan (IT), were included. Twenty-two patients matched for age and with analogous inclusion criteria except for indication to RME treatment were enrolled in the control group. Clinical otolaryngological evaluation, pure tone audiometry and tympanogram were performed at the beginning of treatment (T0), at the end of the expansion (T1) and at 6-month follow-up (T2). MAIN OUTCOME MEASURES: Air-bone gaps and tympanogram results at each time interval. RESULTS: In the main group, RME allowed a statistically significant improvement of air-bone gaps (according to frequency, p < 0.001-0.089 T0 vs. T1 and < 0.001-0.044 T0 vs. T2, Friedman's test) and tympanometry results (p = 0.002 T0 vs. T1 and p < 0.001 T0 vs. T2, Friedman's test). Improvements were stable during follow-up and were significantly better in the main group than in the control group. CONCLUSION: CHL and middle ear effusion improved significantly overtime during RME and after 6 months of follow-up.

PURPOSE: Intranasal cocaine is known to potentially lead to midline destructive lesions. The present systematic review was undertaken to systematically define the localization of cocaine-induced midline destructive lesions and their prevalence and to propose a practical classification of these lesions. METHODS: A PRISMA-compliant systematic review was performed in multiple databases with criteria designed to include all studies published until March 2021 providing a precise definition of cocaine-induced midline lesions in humans. We selected all original studies except case reports. After duplicate removal, abstract and full-text selection, and quality assessment, we reviewed eligible articles for lesion localization, patients' demographics, exposure to cocaine, and relationship with external nose destruction. RESULTS: Among 2593 unique citations, 17 studies were deemed eligible (127 patients). All studies were retrospective case series. The destructive process determined a septal perforation in 99.2% of patients. The distribution prevalence decreased from the inferior third of the sinonasal complex (nasal floor and inferolateral nasal wall, respectively, 59% and 29.9% of patients) to the middle third (middle turbinate and ethmoid, 22.8% of patients), and ultimately to neurocranial structures (7.9% of patients). Nasal deformities were inconsistently reported across reviewed studies. Cocaine use duration, frequency, and status were reported only occasionally. CONCLUSION: Based on the distribution prevalence observed, we propose a four-grade destruction location-based classification. Future prospective studies following the evolution of cocaine-induced lesions are needed to validate our classification, its relationship with lesion evolution, and whether it represents a reliable tool for homogeneous research results reporting.

PURPOSE: Cleft palate children have a higher incidence of otitis media with effusion, more frequent recurrent acute otitis media episodes, and worse conductive hearing losses than non-cleft children. Nevertheless, data on adenoidectomy for middle ear disease in this patient group are scarce, since many feared worsening of velopharyngeal insufficiency after the procedure. This review aims at collecting the available evidence on this subject, to frame possible further areas of research and interventions. METHODS: A PRISMA-compliant systematic review was performed. Multiple databases were searched with criteria designed to include all studies focusing on the role of adenoidectomy in treating middle ear disease in cleft palate children. After duplicate removal, abstract and full-text selection, and quality assessment, we reviewed eligible articles for clinical indications and outcomes. RESULTS: Among 321 unique citations, 3 studies published between 1964 and 1972 (2 case series and a retrospective cohort study) were deemed eligible, with 136 treated patients. The outcomes were positive in all three articles in terms of conductive hearing loss improvement, recurrent otitis media episodes reduction, and effusive otitis media resolution. CONCLUSION: Despite promising results, research on adenoidectomy in treating middle ear disease in the cleft population has stopped in the mid-Seventies. No data are, therefore, available on the role of modern conservative adenoidectomy techniques (endoscopic and/or partial) in this context. Prospective studies are required to define the role of adenoidectomy in cleft children, most interestingly in specific subgroups such as patients requiring re-tympanostomy, given their known risk of otologic sequelae.

Using both endoscope and exoscope in cleft soft palate surgery is not widespread, despite the potential advantages related to view magnification, ergonomic posture of the surgeon, and involvement of the surgical team.The aim of the current study is to compare endoscopic (Olympus Visera©) and exoscopic (Karl-Storz Vitom©) assistance in cleft soft palate surgery in a preclinical cadaver setting.A formalin fixed specimen was dissected to mimic the anatomical conditions of a cleft soft palate.Ten young surgeons with limited experience in transoral surgery were involved in the exercitation on the specimen.The exercitation consisted of 4 tasks: (1) device setting; (2) identification of muscle plane; (3) muscle suturing; (4) oral mucosa suturing.Participants were timed while performing each task both with exoscope and endoscope and asked to fill in 2 questionnaires related to the visual systems used (NASA Task Load System TLS and VAS 1-10).All surgeons completed the 4 tasks with both the endoscope and exoscope. The execution times were similar except for faster setting of the exoscope. Participants felt that completing surgical exercises using the exoscope required less physical, intellectual, and temporal efforts compared to the endoscope. The exoscope was also more appreciated for its handling, 3D visualization, and limited encumbrance.Exoscope scored better both at NASA TLS and VAS 1-10 and required a faster setting than endoscope. Further clinical in-vivo studies are required to explore the advantages of these devices in cleft palate repair.
RESUMO
Introduction: SARS-CoV-2 is a respiratory virus supposed to enter the organism through aerosol or fomite transmission to the nose, eyes and oropharynx. It is responsible for various clinical symptoms, including hyposmia and other neurological ones. Current literature suggests the olfactory mucosa as a port of entry to the CNS, but how the virus reaches the olfactory groove is still unknown. Because the first neurological symptoms of invasion (hyposmia) do not correspond to first signs of infection, the hypothesis of direct contact through airborne droplets during primary infection and therefore during inspiration is not plausible. The aim of this study is to evaluate if a secondary spread to the olfactory groove in a retrograde manner during expiration could be more probable. Methods: Four three-dimensional virtual models were obtained from actual CT scans and used to simulate expiratory droplets. The volume mesh consists of 25 million of cells, the simulated condition is a steady expiration, driving a flow rate of 270 ml/s, for a duration of 0.6 seconds. The droplet diameter is of 5 µm. Results: The analysis of the simulations shows the virus to have a high probability to be deployed in the rhinopharynx, on the tail of medium and upper turbinates. The possibility for droplets to access the olfactory mucosa during the expiratory phase is lower than other nasal areas, but consistent. Discussion: The data obtained from these simulations demonstrates the virus can be deployed in the olfactory groove during expiration. Even if the total amount in a single act is scarce, it must be considered it is repeated tens of thousands of times a day, and the source of contamination continuously acts on a timescale of several days. The present results also imply CNS penetration of SARS-CoV-2 through olfactory mucosa might be considered a complication and, consequently, prevention strategies should be considered in diseased patients.

BACKGROUND: Skull base chordomas (SBC) are rare malignant tumors and few factors have been found to be reliable markers for clinical decision making and survival prognostication. The aim of the present work was to identify specific prognostic factors potentially useful for the management of SBC patients. METHODS: A retrospective review of all the patients diagnosed and treated for SBC at the Fondazione IRCCS Istituto Neurologico "Carlo Besta" between January 1992 and December 2017 has been performed. Survival analysis was performed and a logistic regression model was used. Statistically significant predictors were rated based on their log odds in order to preliminarily build a personalized grading scale-the Peri-Operative Chordoma Scale (POCS). RESULTS: Fifty-nine primary chordoma patients were included. The average follow-up from the first treatment was 82.6 months (95% CI, 65.5-99.7). POCS was built over PFS and MR contrast enhancement (intense vs mild/no, value 4), preoperative motor deficit (yes vs no, value 3), and the development of any postoperative complications (yes vs no, value 2). POCS ranges between 0 and 9, with higher scores being associated with reduced likelihood of survival and progression-free state. CONCLUSIONS: Our results show that preoperative clinical symptoms (motor deficits), surgical features (extent of tumor resection and surgeon's experience), development of postoperative complications, and KPS decline represent significant prognostic factors. The degree of MR contrast enhancement significantly correlated to both OS and PFS. We also preliminarily developed the POCS as a prognostic grading scale which may help neurosurgeons in the personalized management of patients undergoing potential adjuvant therapies.

PURPOSE: Stapes surgery, despite the introduction of lasers and endoscopes, still represents a challenging procedure. Recently introduced 3-dimensional exoscopes have known advantages in otological surgery. This study aims to evaluate exoscopes role in stapes surgery, both from a surgical perspective and on the educational profile. METHODS: Seven consecutive otosclerosis patients underwent single-sided endaural laser stapedotomy with a 4K 3-dimensional exoscope. The surgical setting allowed all operating room personnel 3-dimensional vision. Pre- and postoperative pure tone audiometry and air-bone gaps, and information on the postoperative course and complications were systematically collected. An informal ergonomic evaluation was carried out by the operating room personnel and an informal didactic evaluation was provided by the trainees. A comparable group of microscope-assisted stapedotomy patients undergoing the same procedures and evaluations was chosen as a control group. RESULTS: Outcomes were solid in all patients, median air-bone gap decreased from 26.5 to 10 dB at the 3-month evaluation (p = 0.01, Wilcoxon's test). No vertigo, tinnitus, or facial palsy was reported. The median operating time was 40 min. The compact design and configuration of the exoscope allowed more practical management of the operating theater. All personnel had the chance for a better understanding of the procedure and trainees felt more confident when asked to identify surgical landmarks and procedure steps. Audiological outcomes, operative times, and complication rates were not different between study and control groups. CONCLUSION: Though further validation and systematic comparison with microscope- and endoscope-assisted stapedotomy are required, the exoscope proved a safe, practical, and educational tool.

PURPOSE: Smell alterations are a symptom of COVID-19 and have been associated with olfactory cleft mucosal thickening (OCMT). Although their pathogenesis is unclear, evidences link them to viral neuroinvasive potential. This study aims at estimating the prevalence of OCMT in CT scans of COVID-19 patients and investigating its clinical correlates. METHODS: In a single-institution retrospective cross-sectional study, we included all patients hospitalized for COVID-19 undergoing head CT scan for any reason. Exclusion criteria were history of recent head trauma or chronic rhinosinusitis; opacification > 2 mm in any sinonasal space other than the olfactory cleft; CT performed during/after invasive ventilation or feeding via nasogastric tube. We recorded the prevalence of OCMT and related it to age, sex, need for invasive ventilation during hospital stay, outcome, length of hospital stay, diffusion of lung SARS-CoV-19 lesions and outcome. RESULTS: 63 eligible patients were identified (39 male, 24 female; median age 77.82 ± 17.77 years). OCMT was identified in 16 patients (25.4%; 95% CI 15.3-37.9%). Patients with OCMT had longer hospital stays (median 16 ± 4 vs. 9 ± 14.5 days, p = .009, Mann-Whitney U test) and required invasive ventilation more frequently than patients without mucosal thickening (OR 4.89, 95% CI 0.96-24.89, p = .063, Fisher's test). No other difference was observed. CONCLUSION: OCMT affects nearly one in four patients hospitalized for COVID-19. It is associated with a worse disease course irrespective of age, sex and diffusion of lung lesions, although with no direct effect on survival.

BACKGROUND: COVID-19 is an infectious disease caused by a novel coronavirus (SARS-CoV-2). The immunopathogenesis of the infection is currently unknown. Healthcare workers (HCWs) are at highest risk of infection and disease. Aim of the study was to assess the sero-prevalence of SARS-CoV-2 in an Italian cohort of HCWs exposed to COVID-19 patients. METHODS: A point-of-care lateral flow immunoassay (BioMedomics IgM-IgG Combined Antibody Rapid Test) was adopted to assess the prevalence of IgG and IgM against SARS-CoV-2. It was ethically approved ("Milano Area 1" Ethical Committee prot. n. 2020/ST/057). RESULTS: A total of 202 individuals (median age 45 years; 34.7% males) were retrospectively recruited in an Italian hospital (Milan, Italy). The percentage (95% CI) of recruited individuals with IgM and IgG were 14.4% (9.6-19.2%) and 7.4% (3.8-11.0%), respectively. IgM were more frequently found in males (24.3%), and in individuals aged 20-29 (25.9%) and 60-69 (30.4%) years. No relationship was found between exposure to COVID-19 patients and IgM and IgG positivity. CONCLUSIONS: The present study did show a low prevalence of SARS-CoV-2 IgM in Italian HCWs. New studies are needed to assess the prevalence of SARS-CoV-2 antibodies in HCWs exposed to COVID-19 patients, as well the role of neutralizing antibodies.

Among cephalgias, cluster headache (CH) is the rarest and the most disabling, explaining the appellation of "suicide headache." Up to 20% of chronic CH reveals to be resistant to pharmacological treatments, in which case interventional procedures should be considered. Many reports evaluated invasive approaches and a wide strand of research is dedicated to the sphenopalatine ganglion. Our paper will now be focused on providing an overview on modern applications on the sphenopalatine ganglion (SPG), their outcomes, and their feasibility in terms of risks and benefits. The group reviewed the international literature systematically for procedures targeting the sphenopalatine ganglion and its branches for episodic and chronic CH, including block, stimulation, radiofrequency, stereotactic radiosurgery, and vidian neurectomy. Seventeen articles fixed our inclusion criteria. Comparing the outcomes that have been analyzed, it is possible to notice how the most successful procedure for the treatment of refractory chronic and episodic CH is the SPG block, which reaches respectively 76.5% and 87% of efficacy. Radiofrequency has a wide range of outcomes, from 33 to 70.3% in CCH. Stimulation of SPG only achieved up to 55% of outcomes in significant reduction in attack frequency in CCH and 71% in ECH. Radiosurgery and vidian neurectomy on SPG have also been analyzed. Generally, ECH patients show better response to standard medical therapies; nevertheless, even this more manageable condition may sometimes benefit from interventional therapies mostly reserved for CCH. First results seem promising and considering the low frequency of side effects or complications, we should think of expanding the indications of the procedures also to those conditions. Outcomes certainly suggest that further studies are necessary in order to understand which method is the most effective and with less side effects. Placebo-controlled studies would be pivotal, and tight collaboration between neurologists and otorhinolaryngologists should also be central in order to give correct indications, which allow us to expect procedures on the SPG to be an effective and mostly safe method to control either refractory ECH or CCH.

PURPOSE: Odontogenic sinusitis and sinonasal complications of dental disease or treatment (SCDDT) represent a heterogeneous group of conditions that often require multidisciplinary care. The present study aims to prospectively validate a classification and treatment protocol for SCDDT patients. METHODS: One hundred twenty-eight consecutive patients (73 females and 45 males, mean age 52.4 years) affected by SCDDT not responding to dental and medical therapy were classified and surgically treated according to the proposed protocol. The protocol classified patients into three aetiology-based groups (preimplantologic, implantologic, and related to traditional dental diseases and procedures, respectively). The groups were further divided into classes according to the presence of oro-antral communications and/or dislocated dental hardware. Each condition was treated according to the class-related, protocol-defined treatment, by either a transnasal or combined transnasal/transoral approach. All patients were successfully classified according to our protocol. None of the proposed classes were redundant, and no condition fell outside the definitions. RESULTS: The surgical treatment protocol proved to be adequate and effective, in that 125 of the 128 patients completely recovered after surgical treatment. CONCLUSIONS: The term SCDDT and the consequent classification proposed by the authors appear, therefore, to be nosologically correct. Furthermore, the protocol-related proposed treatment appears to be clinically sound, with a success rate nearing 98%.

Headache secondary to sinonasal disease is still overestimated in the diagnostic pathway of cephalalgia. Contrary to belief, so-called sinus headaches are fairly uncommon and seen mostly in acute sinusitis or acute exacerbations. Even though literature has written extensively about the prevalence of migraines in self-diagnosed or primary care-diagnosed sinus headache, there is only a small body of literature regarding the real prevalence of pain and headache occurring during acute and chronic sinusitis.We reviewed the current literature and clarified the differences in presentation of pain for acute and chronic sinusitis, highlighting the higher prevalence of pain in chronic rhinosinusitis without polyps versus with polyps. Furthermore, we stressed the need for a rethinking in the clinical diagnosis of sinusitis based on pain as a major symptom.

Electroporation, also known as electrochemotherapy, combines an antineoplastic agent with electroporation, causing localized progressive necrosis in the treated area. Today it is primarily used in the palliative treatment of cutaneous and subcutaneous metastases and has been found to be safe and efficacious in head and neck cancer recurrences. Despite the steady increase in the number of published studies this treatment is not universally available and used systematically in head and neck carcinomas. To shed light on its limitations and analyze treatment outcome we have, therefore, reviewed all available literature regarding this topic. This systematic review includes 16 studies on head and neck squamous cell carcinoma and reports the data of 200 treated patients. The combined results show a very heterogeneous overall response rate, ranging from 0 to 100%, while the complete response rate ranges between 0 and 83.3%. No major side effects have been described in those who used electrochemotherapy as a mono modality palliative treatment. This systematic review shows how standardization of treatment is still pivotal to achieve a more homogeneous response rate in the approach to head and neck tumors. In conclusion, due to the scarcity of alternatives of treatment in advanced stage cancer in this anatomical region and the good tolerability and mostly high success rates of electrochemotherapy, this palliative approach should be taken into consideration in these patients.
