Lesson learned in endoscopic endonasal dens resection for C1-C2 spinal cord decompression.

PURPOSE: Endoscopic endonasal approach (EEA) is the safest and most effective technique for odontoidectomy. Nevertheless, this kind of approach is yet not largely widespread. The aim of this study is to share with the scientific community some tips and tricks with our ten-year-old learned experience in endoscopic endonasal odontoidectomy (EEO), which remains a challenging surgical approach. MATERIAL AND METHODS: Our case series consists of twenty-one (10 males, 11 females; age range of 34-84 years) retrospectively analyzed patients with ventral spinal cord compression for non-reducible CVJ malformation, treated with EEA from July 2011 to March 2019. RESULTS: The results have recently been reported in a previous paper. The only intraoperative complication observed was intraoperative cerebrospinal fluid (CSF) leak (9.5%), without any sign of post-operative CSF leak. CONCLUSIONS: Considering our experience, EEO represents a valid and safe technique to decompress neural cervical structures. Despite its technical complexity, mainly due to the use of endoscope and the challenging surgical area, with this study we encourage the use of EEO displaying our experience-based surgical tips and tricks.

Dupilumab improves sleep quality in chronic rhinosinusitis with nasal polyps.

PURPOSE: Chronic rhinosinusitis with nasal polyps (CRSwNP) often alters sleep quality. Dupilumab emerged as an innovative and effective therapy for refractory/recurrent severe CRSwNP. The aim of this observational retrospective study was to evaluate the sleep quality in patients with CRSwNP who underwent treatment with dupilumab. MATERIALS AND METHODS: Forty-five patients treated with dupilumab for CRSwNP were enrolled. Clinical parameters (age, sex, comorbidities, Nasal Polyp Score - NPS, Asthma Control Test - ACT), nasal cytology, quality of life (Sino Nasal Outcome Test 22 - SNOT-22), sleep quality (Pittsburgh Sleep Quality Index - PSQI, Epworth Sleepiness Scale - ESS), and risk of sleep apnea (STOP-BANG) were recorded before treatment (T0), and after 3 (T1), 6 (T2), and 12 months (T3). RESULTS: NPS, ACT and SNOT-22 total score improved during treatment (p < 0.05). Meanwhile, all sleep parameters evaluated with SNOT-22, ESS and PSQI improved over time (p < 0.001), expect for PSQI Use of sleeping medications. Indeed, sleep drugs are rarely used before and during the treatment. The global sleep quality was classified as poor in 88.9 % of cases at T0 and decreased to 5.7 % at T3. A high risk of sleep apnea was revealed by the STOP-BANG in 68.9 % of cases at T0 and 2.8 % of patient at T3 (p < 0.001). CONCLUSIONS: Dupilumab improves the sleep quality and reduce the risk of sleep apnea in patients with severe CRSwNP. Its favorable effect occurs within 3 months and is maintained during the treatment.

Therapeutic approaches to sinonasal NUT carcinoma: a systematic review.

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.

The importance of follow-up examinations in chronic rhinosinusitis with nasal polyposis.

PURPOSE: Clinical examinations following functional endoscopic sinus surgery (FESS) for chronic rhinosinusitis with nasal polyps (CRSwNP) are critical for physicians to assess results of the intervention and to early identify recurrences. However, no clear consensus on the frequency and timing of clinical examinations following surgery exists. The aim of this study was to analyze CRSwNP recurrences after FESS with a specific focus on the adherence to follow-up examinations. MATERIALS AND METHODS: Sixty patients who underwent FESS for CRSwNP were enrolled. Clinical parameters were recorded. Adherence to follow-up examinations with nasal fiber optic endoscopy and regular administration of nasal steroids were analyzed. RESULTS: Adherence to periodic clinical examinations and regular treatment with nasal steroids was 25 %. CRSwNP recurrence was observed in 56.7 % of cases at the last follow-up examination. No statistically significant difference concerning nasal symptoms was observed between patients with and without current recurrence (p > 0.05). Subjects who underwent regular examinations and prompt treatment of small recurrences had a lower probability of relapse at their last examination (7.7 % versus 38.2 %, respectively; p < 0.001). Polyp grade > 2 in patients with or without adherence were seen in 15.4 % and 42.9 % of cases, respectively (p < 0.05). CONCLUSIONS: Adherence to follow-up examinations with nasal optic fiber endoscopy is crucial to early identify recurrence after surgery and promptly treat it with medical therapy.

The role of intranasal corticosteroids in chronic rhinosinusitis with nasal polyposis treated with dupilumab.

PURPOSE: Dupilumab represents an innovative and effective therapy for refractory/recurrent severe chronic rhinosinusitis with nasal polyps (CRSwNP). Intranasal corticosteroids should be used during treatment with biological agents. However, adherence to nasal therapy may not be complete. The aim of this study was to evaluate the role of intranasal corticosteroids in patients with CRSwNP who underwent treatment with dupilumab. MATERIALS AND METHODS: Fifty-two patients treated with dupilumab for CRSwNP were enrolled. Clinical parameters (age, sex, comorbidities, blood eosinophils, Nasal Polyp Score - NPS, Visual Analogue Scale - VAS - for smell loss, Asthma Control Test - ACT), quality of life (Sino Nasal Outcome Test 22 - SNOT-22 questionnaire), nasal cytology, and adherence to regular administration of intranasal corticosteroids were recorded before treatment (T0), and after 3 (T1), 6 (T2), and 12 months (T3). RESULTS: NPS, VAS for smell, ACT and SNOT-22 total score and subscores improved during treatment (p < 0.05). Blood eosinophils reached a peak at T1-T2 and then decreased toward baseline at T3. Adherence to regular treatment with intranasal steroids was 61.5 %. No statistically significant differences in all the clinical outcomes were observed between patients who regularly used intranasal steroids and other subjects (p > 0.05). Nasal cytology showed a decrease of eosinophils and an increase of neutrophils during treatment. CONCLUSIONS: Dupilumab is still effective in patients who are using topical nasal steroids with variable adherence (real world settings).

Long-term evaluation of nasal polyposis recurrence: A focus on multiple relapses and nasal cytology.

PURPOSE: Recurrence of chronic rhinosinusitis with nasal polyps (CRSwNP) is highly variable, reaching 55-60% of cases. Different results about clinical parameters as recurrence predictors has been reported. The aim of this retrospective study was to evaluate CRSwNP recurrence risk after a long-term follow-up (up to 20 years). Moreover, the role of nasal cytology was assessed. MATERIALS AND METHODS: Sixty-one patients who underwent functional endoscopic sinus surgery for CRSwNP were enrolled. Clinical parameters were recorded. Nasal cytology was performed at follow-up examinations. The Kaplan-Meier method was used to obtain the recurrence-free survival curves. The median number of recurrences per year was evaluated. RESULTS: Five- and 10-year recurrence rates were 30.29% and 66.06%, respectively. Median recurrence-free survival was 106 months. Asthma and Aspirin-Exacerbated Respiratory Disease represented predictors of multiple recurrences (p < 0.05). Intranasal steroids were the main treatment to prevent relapses (p < 0.05). Patients with normal cytology at follow-up evaluation had a lower probability to have first recurrence within 10 years (59% of cases), compared to neutrophil or eosinophil infiltrate (100% and 88% of cases, respectively) (p < 0.05). CONCLUSIONS: CRSwNP has a high recurrence risk, also more than 10 years after surgery. Nasal cytology may identify subjects with a higher risk of early recurrence.

Pignat's vertical partial laryngectomy with crico-hyoido-epiglotto-plasty.

PURPOSE: Pignat's partial laryngectomy with crico-hyoido-epiglotto-plasty (CHEPL) is a vertical laryngectomy with resection of the anterior portion of the thyroid cartilage and reconstruction with a wires net and the subhyoid muscles. The aim of this retrospective study was to evaluate and analyze oncologic and functional outcomes in patients affected by laryngeal squamous cell carcinoma and treated with Pignat's partial laryngectomy. METHODS: Seventy patients with cT1-cT3 glottic cancer were surgically treated with Pignat's technique. EXCLUSION CRITERIA: invasion of posterior cricoid arch, more than 3 mm under glottis, of more than one arytenoid, of posterior portion of thyroid cartilage, of the suprahyoid epiglottis. Overall survival, disease free survival, rates of decannulation and enteral feeding were analyzed. RESULTS: 23 (32.9%) pT1, 37 (52.9%) pT2, 5 (7.1%) pT3, 5 (7.1%) pT4a, 64 (91.5%) pN0, 5 (7.1%) pN1, 1 (1.4%) pN2. Adjuvant treatment was administered to 13 patients (18.6%). All patients had tracheotomy. Five year OS and DFS were 81.66 and 77.95%, respectively. A statistically significant DFS difference was observed between early and late stages. Five year local control was 81.16%. Five year larynx preservation rate was 89.16%. Median decannulation time was 12 days. Median duration of enteral nutrition was 16 days. All patients achieved efficient phonation. CONCLUSION: Pignat's partial laryngectomy with CHEPL can represent an alternative to horizontal supracricoid laryngectomy to achieve laryngeal preservation. Good oncologic and functional outcomes are possible as long as indications are followed.

Cochlear Implant Outcomes in Prelingually Deafened Adults with and without Sound Deprivation: Are There Differences in Quality of Life?

BACKGROUND Indications for cochlear implantation (CI) are constantly being updated, and with them, the audiometric results achieved by patients. Patient satisfaction should always be considered, even in patients with lower audiological results. The aim of the present study was to compare quality of life (QoL), self-perceived hearing benefit, and audiometric results between prelingually and postlingually deafened patients, with and without sound deprivation, after CI. MATERIAL AND METHODS The sample included 46 patients with bilateral sensorineural hearing loss: 22 postlingually deafened and 24 prelingually deafened, further subdivided into sound-deprived (n=10) and non-sound-deprived (n=14). Auditory performance was evaluated with pure tone audiometry, speech recognition scores (SRS), and self-perceived hearing benefit, whereas QoL was evaluated with 2 self-reported questionnaires (Comprehensive Cochlear Implant Questionnaire and World Health Organization Quality of Life-BREF). RESULTS Audiometric results were worse in the prelingually deafened than in the postlingually deafened group, and worse in the prelingually deafened patients with sound deprivation. There was no marked difference in perceived CI benefit or QoL between the 2 groups or within the 2 prelingually deafened subgroups. No correlation was found between SRS and duration of CI use or between QoL and SRS in the prelingually and postlingually deafened groups. CONCLUSIONS Our findings demonstrate better auditory performance for the postlingually deafened group and no differences in perceived QoL or benefit of CI between the groups. The sound-deprived patients had equal scores on the perceived QoL questionnaire. These analyses suggest that sound-deprived, prelingually deafened patients may benefit from CI.

Nasal Cytology in Radiofrequency Turbinate Volume Reduction.

INTRODUCTION: Radiofrequency turbinate volume reduction (RFTVR) is an effective treatment of inferior turbinate hypertrophy. RFTVR can reduce epithelial cell alterations in nasal mucosa. The aim of this observational study was to evaluate the effects of RFTVR on nasal obstruction and cytology, stratifying for different types of rhinitis. METHODS: Nasal cytology and subjective nasal obstruction were evaluated on 113 patients before RFTVR (T0) and after 3 months (T1). The patients were divided into groups on the basis of the underlying disease: allergic rhinitis, nonallergic rhinitis, rhinitis medicamentosa, and other diseases (e.g., hormonal-based turbinate hypertrophy). RESULTS: Nasal cytology at T0 identified 42 patients with allergic rhinitis, 40 with nonallergic rhinitis, 19 with rhinitis medicamentosa, and 12 with other diseases. An improvement of nasal cytology at T1 was observed in 29.2% of cases. They mainly consisted of patients with nonallergic rhinitis with neutrophils, whose neutrophil infiltrate decreased. Only 2 cases (1.7%) showed a worsening of nasal cytology at T1. A statistically significant decrease in subjective nasal obstruction was observed for every group (p < 0.05). Higher differences of nasal obstruction between T0 and T1 were found in patients with rhinitis medicamentosa or other diseases. CONCLUSION: RFTVR represents a safe and effective treatment for turbinate hypertrophy of various etiology. It is not responsible for a worsening of inflammatory infiltrate of the nasal mucosa.

HPV Meets APOBEC: New Players in Head and Neck Cancer.

Besides smoking and alcohol, human papillomavirus (HPV) is a factor promoting head and neck squamous cell carcinoma (HNSCC). In some human tumors, including HNSCC, a number of mutations are caused by aberrantly activated DNA-modifying enzymes, such as the apolipoprotein B mRNA editing enzyme catalytic polypeptide-like (APOBEC) family of cytidine deaminases. As the enzymatic activity of APOBEC proteins contributes to the innate immune response to viruses, including HPV, the role of APOBEC proteins in HPV-driven head and neck carcinogenesis has recently gained increasing attention. Ongoing research efforts take the cue from two key observations: (1) APOBEC expression depends on HPV infection status in HNSCC; and (2) APOBEC activity plays a major role in HPV-positive HNSCC mutagenesis. This review focuses on recent advances on the role of APOBEC proteins in HPV-positive vs. HPV-negative HNSCC.

Validation and Reliability of the Italian Version of the Speech Handicap Index.

BACKGROUND: Speech problems negatively affect the quality of life of patients with oral and oropharyngeal cancer. An appropriate self-rating questionnaire named Speech Handicap Index (SHI) was developed for these individuals. The aim of this study was the cross-cultural adaptation and the validation of the Italian version of the SHI. METHODS: Fifty-two patients surgically treated for oral or oropharyngeal cancer and 100 healthy individuals without speech articulation disorders were included in the study. An Italian version of the SHI was cross-culturally adapted. Internal consistency, test-retest reliability, construct, and clinical and group validity were calculated. RESULTS: Cronbach's alpha coefficient was 0.977. The test-retest reliability was excellent (r between 0.883 and 0.998). There was a good correlation between the total SHI score and the overall speech quality item (p < 0.001), and between the former and speech intelligibility and articulation scales (p < 0.001). The SHI was able to distinguish between patients and healthy subjects (p < 0.001). There was a statistically significant correlation between the total SHI score and tumor stage (p = 0.003). CONCLUSIONS: The Italian version of the SHI showed high values of reliability and validity scores. It is a good instrument to evaluate the impact of speech impairment in patients with oral and oropharyngeal cancer.

PYHIN genes as potential biomarkers for prognosis of human papillomavirus-positive or -negative head and neck squamous cell carcinomas.

The aim of the present study is to determine the expression levels of PYHIN (IFI16 and AIM2) and APOBEC3 (A3A, A3B, A3C, A3D, A3F, A3G, and A3H) gene family members in a cohort of patients with head and neck squamous cell carcinoma (HNSCC) and assess their potential correlation with human papillomavirus (HPV) infection status, clinical characteristics, and survival. For this purpose, 34 HNSCC tissue specimens along with healthy surrounding mucosa were collected from patients surgically treated for HNSCC. Nucleic acids were isolated to assess the presence of HPV and the expression levels of selected molecular markers. Survival analysis was carried out using the Kaplan-Meier method. In HPV-negative (HPV-) HNSCCs, we detected low mRNA expression levels of IFI16, A3A, and A3B, whereas these genes were upregulated of 2-100 folds in HPV-positive (HPV+) tumors (p < 0.05). Interestingly, AIM2 gene expression levels were predominantly unchanged in HPV+ HNSCCs compared to their HPV- counterparts, in which AIM2 was predominantly upregulated (10% vs. 50% of patients). In HPV- tumors, upregulation of TP53, NOTCH1, PD-L1, and IFI16 correlated with lower occurrence of nodal metastases. On the other hand, the expression of APOBEC family members did not correlate with clinical characteristics. Regarding survival, patients with upregulated A3F gene expression had a worse prognosis, while patients without changes in A3H expression had a lower survival rate. In conclusion, our findings indicate that the innate immune sensors IFI16 and AIM2 and some APOBEC family members could be potentially used as biomarkers for disease outcome in HNSCC patients regardless of HPV presence.

The Endoscopic Endonasal Approach to Craniovertebral Junction Pathologies: Surgical Skills and Anatomical Study.

INTRODUCTION: Surgical anterior decompression is the treatment of choice for symptomatic irreducible ventral craniovertebral junction (CVJ) compression. Along with the classic transoral approach, the endoscopic endonasal approach has evolved and is gaining growing success. MATERIALS AND METHODS: In this work we discuss the surgical technique, give a complete step-by-step description of dissection of the craniovertebral junction and report a specific case of endoscopic endonasal odontoidectomy with use of a high-definition (HD) three-dimensional (3D) endoscope. DISCUSSION: The extended endonasal approach exploits an anatomical corridor to the odontoid process, involving only a small incision in the nasopharynx and sparing palate integrity. The most important limitation of the technique is 2D visualization, which hinders correct recognition of anatomical structures. CONCLUSION: The endoscopic endonasal route to the odontoid process has proven to be a feasible, safe and well-tolerated procedure. Anatomical study is very important for better understanding of the 3D anatomy of the CVJ and relation of critical neurovascular structures to specific bony and muscular landmarks.

Endoscopic versus conventional septoplasty: objective/subjective data on 276 patients.

PURPOSE: Endoscopic approach represents a valid alternative to conventional septoplasty. The aim of this study is to analyze the objective and subjective data on 276 patients, who underwent traditional (147) or endoscopic (129) septoplasty. METHODS: This is a prospective observational study on 276 consecutive patients affected by deviated nasal septum (DNS), who underwent isolated septoplasty between 2011 and 2018. 147 of them were treated using an "open" approach, while 129 were treated with an endoscopic approach. The two groups were compared 3 months after surgery: the objective results (complications such as bleeding, hematoma, pain, synechiae, septal tears and incomplete correction), objective (rhinomanometric data) and subjective measurements (NOSE questionnaires). RESULTS: Both techniques are effective in decreasing nasal obstruction and discharge. Complications such as pain, synechiae, early postoperative bleeding, septal tears and incomplete correction are less frequent in the endoscopic group (p < 0.05). The rhinomanometric analysis reveal improvement in both groups without statistical differences. Subjective questionnaires show a good symptoms relief with an improved quality of life in all 276 patients without statistical difference between the two gropus. CONCLUSIONS: Both techniques are effective in reducing nasal obstruction and related symptoms with fewer overall complications in the endoscopic approach. The endoscope provides improved field of view, less mucosal damages and a more anatomic dissection. Finally, such approach can be a valuable teaching tool for assistants, residents and students.

Psychological distress and coping in nasopharyngeal cancer: an explorative study in Western Europe.

Nasopharyngeal carcinoma (NPC) is the head and neck cancer with the greatest impact on patients' quality of life. The aim of this explorative study is to investigate the psychological distress, coping strategies and quality of life of NPC patients in the post-treatment observation period. Twenty-one patients disease-free for at least two years were assessed with a medical and a psycho-oncological evaluation. Clinically relevant depressive symptoms (CRD) were present in 23.8% of patients and 33.3% reported clinically relevant anxiety symptoms (CRA). Patients with CRD and CRA showed a significantly higher score in the use of hopelessness/helplessness and anxious preoccupation coping strategies and a worse quality of life. Even in the post-treatment period, about a quarter of patients showed CRD and CRA. Results showed that patients with high anxiety or depressive symptoms seem to use dysfunctional coping strategies, such as hopelessness and anxious preoccupation, more than patients with lower levels of anxiety and depression. The use of these styles of coping thus seems to be associated to a higher presence of CRA or CRD symptomatology and to a worse quality of life.

Detection of herpesviruses 1-6 and community-acquired respiratory viruses in patients with chronic rhinosinusitis with nasal polyposis.

OBJECTIVE: To evaluate the prevalence of human herpesviruses (HHV) 1-6 and community-acquired respiratory viruses (CARVs) in specimens from patients with nasal polyposis undergoing functional endoscopic sinus surgery (FESS) and investigate the potential clinical role. METHODS: Viral occurrence was evaluated by molecular methods in polyp, turbinate mucosa, and pre- and postoperative scraping specimens from 35 consecutive patients at different time points in relation to FESS. RESULTS: Overall, 21 patients (60%) were positive to at least one virus in at least one specimen; in particular, 12.1% of all specimens for HHV-6 (3/35 polyps, 11/31 turbinates, 1 presurgical scraping) and 10.5% for Epstein-Barr virus (EBV) (8/35 polyps, 3/31 turbinates, 1/29 pre- and 1/29 postsurgical scraping), followed by CMV and HSV-1 (both 1.6%; 1/35 polyps, 1/29 postsurgical scraping and 2/35 polyps, respectively). EBV positivity tended to be higher in polyps, as well as HHV-6 in adjacent healthy turbinate mucosa, although no significant association was found. Only one preoperative cytological specimen was positive to parainfluenza virus-1. CONCLUSION: No association between the development of nasal polyps, herpesviruses and CARVs seems to exist. However, the higher EBV frequency in polyps could suggest a causative role or persistence in the inflammatory lymphoid tissue.

Ear, nose and throat foreign bodies: the experience of the Pediatric Hospital of Turin.

AIM: Ear, nose and throat (ENT) foreign body (FB) injuries represent an emerging problem in the paediatric population because of their human and social costs. The aim of the study is the site-specific evaluation of FB injuries in the paediatric population referred to the emergency department of the Pediatric Hospital of Turin. METHODS: This retrospective analysis was carried out sifting medical reports between 2002 and 2011. We collected information about 338 patients' FB characteristics, complications and hospitalisation. RESULTS: The mean age was 4.2 ± 2.9 years. Nose and ear are the most involved anatomical sites, followed by pharynx, oesophagus and trachea-bronchi. The most common FBs are balls, beads and toys parts (29.6%), followed by fishbones (13.6%). A lower mean age is observed in tracheo-bronchial and oesophageal FBs. The 9.2% of cases reported complications. CONCLUSIONS: A quick and proper diagnosis followed by an effective treatment of FB injuries and their complication is mandatory. Surveillance registries have a key role in prevention and management of FB injuries; useful information can be obtained also for nurse and ENT specialist training in order to create professionals ready to recognise and manage FB injuries in the most effective way.

Iatrogenic rhinopharyngeal isolated argyria induced by silver-containing nasal drug.

Localized nasal argyria has been reported in 3 published articles as secondary to occupational exposure and involving the anterior part of the nose. No previous cases of such pathology involving the rhinopharynx were described. Here we report the first case of localized argyria of the roof and of the posterior wall of the rhinopharynx secondary to prolonged use of nasal drops containing colloidal silver protein. The recognition of such pathology can be useful to increase the number of conditions that must be considered in the differential diagnosis of rhinopharyngeal mucosa alterations.

A technical note about flap fixation technique to prevent salivary fistulas in reconstructive oral cavity surgery.

Salivary fistulas are frequent complications in oral oncological reconstructive surgery by means of pedicled or free flaps. The most common risk factors are malnutrition, advanced disease, and healing alterations due to radiation therapy or infections. However, they can be observed also in healthy patients where the flap suture breakdown is the only cause. During the reconstructive phase, flaps are anchored to the remnant tongue, hyoid bone, and residual gingival mucosa; the last structure often does not offer suitable margins for a strong suture. The aim of this study was to propose a transmandibular fixation of the flap that allows, in a safe, efficient, and unexpensive way, the creation of a saliva-proof neofloor of the mouth, independently from the quality and thickness of residual gingival mucosa.
