RESUMO
PURPOSE: Among the treatment options for Obstructive Sleep Apnea (OSA), intrapharyngeal surgery has undergone significant changes and received solid scientific support. However, it is crucial to identify the best candidate. This study aims to present the results of the modified Alianza technique in our clinic to show the differences in the impact of surgery on supine and non-supine apnea levels in moderate-severe OSA patients. METHODS: Adult patients affected by moderate-severe OSA (Apnea-Hypopnea Index (AHI) > 15), having circular palatal collapse, and candidates for modified Alianza Tecnique were retrospectively enrolled. Each subject performed polysomnography pre- and post-operatively, and the follow-up check was performed after at least six months. RESULTS: This study enrolled 24 patients who underwent the Modified Alianza technique for sleep apnea. We found significant reductions in both supine and non-supine AH) after surgery. Non-supine AHI showed a greater reduction (from 20.89 to 11.64 episodes/hour, p = 0.0001) than supine AHI (from 42.51 to 25.93, p = 0.0003). We subsequently divided the patients into two groups based on whether they were affected by positional OSA before surgery. There was a lower percentage decrease in non-supine AHI compared to supine AHI after surgery in patients who were positional before surgery, but this difference was not statistically significant. Conversely, in the non-positional patient group, there was a higher decrease in non-supine AHI compared to supine AHI, although this was not statistically significant. CONCLUSION: The Modified Alianza Tecnique leads to notable enhancement in AHI among patients with OSA. Non-supine apneas exhibit a more favorable response to the surgery than supine apneas.
RESUMO
Approximately 45% of adults snore occasionally, and 25% snore regularly, with a higher prevalence in men and an increase among postmenopausal women due to hormonal changes. Snoring is a health concern linked to vascular disease and decreased quality of life for both snorers and their bed partners. Effective snoring treatment, which aims to reduce or eliminate the sound, is challenging and depends on factors like age, comorbidities, disease severity, and anatomical features. This review aims to provide a systematic overview of the current literature on the effects of positional therapy (PT) on snoring. Various devices facilitate PT, including anti-snoring pillows and vibration alarms. PT devices maintain head and neck alignment to keep airways open, while head of bed elevation (HOBE) solutions reduce upper airway collapses by elevating the head and trunk. Studies show that PT and HOBE reduce snoring by increasing airway cross-sectional area and decreasing closing pressure. Despite their benefits, these non-surgical treatments have limitations, such as discomfort in certain sleeping positions and intolerance to prolonged head elevation. While reducing snoring intensity is critical for health reasons, further comparative studies between the different devices are needed to enhance snoring management.
RESUMO
PURPOSE: Learning how to use barbed sutures and perform Barbed Pharyngoplasty (BP) is challenging due to limited surgical training opportunities. This work aims to design, develop, and validate a new 3D surgical simulator to train ENT residents and specialists in performing BP. METHODS: The Barbed Pharyngoplasty Simulator (BPS) was designed using diagnostic images of the facial mass and testing different materials to replicate the mucosal and bony tissues. ENT specialists with experience in BP and ENT residents were included in the validation study and were asked to perform the Alianza BP. After the simulation, they compiled the Face and Content Validity Questionnaires. RESULTS: The BPS consists of a reusable cranial structure that contains the disposable palatopharyngeal structure, replicating the palatal structures and the tongue. Fifteen experienced ENT specialists and nine residents were included in the study. Findings demonstrated that the BPS faithfully replicated the muscular and fibrous-bony palatopharyngeal structures, with only 11% of residents having a negative opinion of the mucosal tissue. All the participants positively rated the sensation of using surgical instruments on the simulator. Also, ENT residents rated all aspects of the content validity test from normal to excellent, while specialists rated the BPS as a general training tool from normal to excellent; for lateral pharyngoplasty, BP, and Alianza, only 6.7% of participants disagreed with its usefulness, and 13.3% disagreed with it for anterior pharyngoplasty. CONCLUSION: The BPS proposed in this preliminary study can potentially be a valuable tool in BP surgical training for residents and young otolaryngologists.
RESUMO
BACKGROUND: With promising outcomes, platelet-rich plasma (PRP) has recently been suggested as a treatment for olfactory dysfunction (OD). METHODS: Clinical studies utilizing PRP in OD caused by COVID-19, trauma, anesthetic exposure, viral infection, and chronic rhinosinusitis were included in a systematic review. RESULTS: Ten clinical studies were qualitatively analyzed. Six of these studies used the PRP for OD caused by COVID-19, one on OD after functional endoscopic sinus surgery, and three on post-infectious or post-trauma OD. The population included 531 patients, ranging in age from 15 to 63. CONCLUSION: The use of PRP may be a risk-free and efficient therapeutic option with very encouraging outcomes. Indeed, it enhances olfactory perception in patients who not only exhibit COVID-19 infection aftereffects, but also in those who have lost their sense of smell due to trauma, rhinosinusitis, rhinitis, or even surgery. To evaluate the PRP's therapeutic benefits in OD patients and to compare the efficacy of different therapeutic protocols with regard to treatment schedules, there is an urgent need for focused controlled trials.
RESUMO
Obstructive Sleep Apnea (OSA) is characterized by repetitive collapse of the upper airway during sleep. Drug-Induced Sleep endoscopy (DISE) is used to identify the collapse site. Among the possible sites of collapse, the epiglottis occurs more frequently than previously described. In this study, we reviewed DISE findings and classified different epiglottic collapse patterns. We found 104 patients (16.4%) with epiglottis collapse (primary 12.5% and secondary 3.9%). We described the following patterns of epiglottis collapse: Anterior-Posterior (AP) collapse with rigid component "trapdoor type" (48%); AP collapse with lax component "floppy type" (13.5%); Lateral- Lateral (LL) collapse with omega shape component "book type" (14.5%); and secondary due to lateral pharyngeal wall or tongue base collapse (24%). The identification of the epiglottic collapse pattern is crucial in decision-making when attempting to ameliorate OSA. These findings in OSA phenotyping could influence the type of treatment chosen.
RESUMO
Obstructive sleep apnea (OSA) surgery is now a viable solution in selected patients and the "remodeling" palatopharyngeal surgery is the most common one. Recently, it has become less invasive with the introduction of barbed sutures (BS). An optimization of surgical techniques is represented by barbed pharyngoplasty (BP), which requires surgical precision and needs efficient and precise oropharyngeal visualization. Consequently, the lighting system is of pivotal importance in BP. The aim of this work is to describe the first experience on the use of a new lighting system, called KLAROTM in BP for OSA. We evaluated the KLARO™ system in 15 consecutives BP for OSA in comparison with conventional headlamp illumination. The visualization of palatopharyngeal muscle in the bottom of the tonsillar fossa, entry and exit needle, such as needle tip, were statistically better with KLAROTM than headlamp illumination for both the surgeon and resident (p < 0.05). No significant differences for the visualization of the posterior pharyngeal wall and uvula were reported. The KLAROTM lighting system allows a satisfied illumination of oral cavity and oropharynx in the majority of cases. We encourage the use of KLAROTM not only in BP for OSA, but in all oral and pharyngeal surgeries, including tonsillectomy and oncological surgery.
RESUMO
We aimed to assess the feasibility of using confocal laser scanning microscopy (CLSM) for the real-time ex vivo examination of histological samples of laryngeal lesions and to evaluate the correlation between CLSM and definitive histological results. This preliminary study included eight consecutive patients with "suspected" laryngeal lesions who were candidates for endoscopic laryngeal surgery. The obtained samples were evaluated using CLSM and classified as "inadequate" or "adequate" (high- and low-grade dysplasia, in situ and invasive carcinoma, positive surgical margin, and inflammatory outbreaks). CLSM showed the macro image in all cases and generated a digital version. All the samples were defined as adequate during CLSM and confirmed at histopathology: low-grade dysplasia (n = 5), low- and high-grade dysplasia (n = 2), and high-grade dysplasia (n = 1). Four samples had an involved resection margin, and three samples revealed the presence of inflammatory outbreaks. CLSM can be applied to larynx pathology with excellent agreement with final histological results.
RESUMO
Septoplasty and turbinate surgery are among the most frequent surgical procedures to improve nasal obstruction and quality of life. These procedures usually imply the presence of congestion, secretions, and crusting related to the movement of the instruments during surgery. However, the use of nasal lavage may reduce this situation. The addition of Hyaluronic acid or Xylitol offers advantages in these washes. This study was a randomized, double-blind, controlled trial. All patients underwent endoscopic septoplasty with inferior turbinate submucosal resection without posterior nasal packing. SNOT-22, main VAS, NOSE, Modified Lund-Kennedy endoscopic scale, number of crusts and adhesions were quantified before and on the day of the surgery, visit three (seven days), visit four (fourteen days), and visit five (twenty-eight days). Forty-seven patients completed the study, divided into a standard saline arm (group 1, 22 patients) and normal saline plus HA and Xylitol arm (group 2, 27 patients). Both treatment groups improved their quality of life and objective parameters during the four weeks of the study. All patients tolerated the nasal irrigations well, and none discontinued the treatments. The study concludes that nasal washes of Aluneb Isotónico® offer several benefits to patients as a protective and preventative agent.
RESUMO
BACKGROUND: Surgical treatment for nasal obstruction caused by nasal valve collapse requires a significant recovery period and risks of complications, while nasal dilators are uncomfortable. Recently, radiofrequency treatment of lateral walls has been used under local anesthesia as an office base surgery. This work aims to assess the efficacy of a new radiofrequency device, the Vivaer™ System (Aerin Medical, Sunnyvale, CA), to treat nasal obstruction through a systematic review and meta-analysis. METHODS: Two researchers independently reviewed the literature up to December 2021. Studies on patients seeking treatment for nasal obstruction due to nasal valve collapse were included in the analysis. RESULTS: Four studies (218 patients) met the inclusion criteria and treated the nasal valve regions bilaterally with the Aerin Medical Vivaer™ System. After the treatment, the NOSE score was reduced at three months postoperatively. Minor adverse events were reported in the included studies, and two showed no complications. None of the studies reported changes in the external appearance of the nose. CONCLUSION: The radiofrequency treatment using the Vivaer device can be useful for treating nasal valve collapse, improving significantly subjective breathing symptom scores. Further studies on a large scale are needed to confirm these results.

Allergic Rhinitis (AR) is a chronic inflammatory disease of sino-nasal mucosa, is IgE-mediated, and affects 10-40% of the global population. This study aimed to compare the efficacy of nasal administration of Beclomethasone Dipropionate (BDP) delivered via Spray-sol with nasal spray in patients suffering from AR. We included 28 AR patients assigned to one of the two following treatments: the Spray-sol group (BDP via Spray-sol) (n = 13) and the spray group (BDP using a common nasal spray) (n = 15). Both treatments were administered twice daily for 4 weeks. A nasal endoscopy evaluation and Total Nasal Symptom Score were performed at baseline and after treatment. The Spray-sol group showed better results than the spray group regarding nasal endoscopy (edema, p < 0.01; irritation, p < 0.01; secretion, p < 0.01) and nasal symptoms (nasal congestion, p < 0.05; rhinorrhea, p < 0.05; sneezing, p < 0.05; and total score, p < 0.05). No side effects were recorded. These data supported the fact that the use of BDP delivered with Spray-sol is more effective than BDP nasal spray in AR patients. Further studies are needed to confirm these encouraging results.
RESUMO
To date, the use of barbed sutures for the surgical management of patients suffering from obstructive sleep apnea and snoring with retropalatal collapse and vibration has significantly increased. A systematic review was carried out, which included clinical studies that used barbed sutures for the treatment of snoring. A qualitative analysis, including six clinical studies, was conducted. Of these, five were studies on barbed pharyngoplasties, and one study involved a minimally invasive surgical procedure. The population consisted of 176 patients, aged 26 to 58 years old. Overall, the included studies showed a mean gain in the snoring Visual Analog Scale of 5.67 ± 1.88, with a mean preoperative value of 8.35 ± 1.17 and a postoperative value of 2.68 ± 1.27. No major complications were described. Given the lack and heterogeneity of this evidence, the conclusion calls for being cautious. In carefully selected snorers and obstructive sleep apnea patients, the use of barbed sutures could represent a valid therapeutic strategy for snoring, ensuring a statistically significant improvement in the subjective parameters. Further studies on a larger scale that assess the role of barbed pharyngoplasties in snoring surgery and more extended follow-up studies are needed in order to confirm these promising results.
RESUMO
Recently, a high-definition 3D exoscope (VITOM), a new magnification system that provides a 3D image of the surgical field, has been introduced. This study aims to describe the first use of VITOM 3D technology in Barbed Pharyngoplasty (BP) for Obstructive Sleep Apnea (OSA). VITOM 3D technology is used to support visualization during BP in a male patient affected by severe OSA with a circular palatal collapse pattern at drug-induced sleep endoscopy. During the surgical procedure, this approach markedly improves the visualization of the surgical field through anatomic details of the oral cavity, facilitating surgical dissection and enhancing the teaching environment. It allows for a better involvement and more interactions during the surgery, as scrubbed and assistant nurses can see the surgical field and anticipate the surgeon's choice of instrument. VITOM 3D technology, by combining a telescope with a standard endoscope, has been successfully used in various surgical disciplines and could be very useful, especially in teaching hospitals. VITOM 3D can guarantee "a real immersive" surgical experience for all participants in the operating room. Economic and efficacy studies would be conducted to support the use of a VITOM-3D exoscope in common clinical practice.
RESUMO
INTRODUCTION: Recently, new non-invasive electrical stimulation devices have been developed with the aim to increase the tongue muscle tone for patients with obstructive sleep apnoea (OSA) and snorers. The aim of this study was to provide a review of the first results found in the literature regarding the efficacy of non-invasive electric stimulation devices for the treatment of primary snoring and OSA. MATERIAL AND METHODS: An electronic search was performed on PubMed/MEDLINE, Google Scholar, and Ovid databases. The PRISMA statement was followed. Databases were searched from inception through September, 2021. RESULTS: Four studies met the criteria for inclusion in this review, for a total of 265 patients. Two devices were included in this review, Apone-Stim 400 Muscle Stimulator and eXciteOSA. All studies suggested that these new devices are effective in improving snoring by approximately 50% after device training, without major complications. However data regarding OSA improvement are conflicting. CONCLUSIONS: Intraoral non-invasive electrical stimulation devices can be considered a valid option to current therapies for snoring. Further studies are needed to support these interesting new devices for treatment of OSA.

PURPOSE: Home sleep apnea testing devices aim to overcome the drawbacks of polysomnography (PSG). Among these, the WatchPAT (WP) (Itamar Medical Ltd., Caesarea, Israel) has recently been introduced on the market for diagnosis of Obstructive Sleep Apnea (OSA). The aim of this review was to provide a comprehensive overview of the studies validating the WP for the diagnosis of sleep-disordered breathing through comparison with PSG. METHODS: A systematic review was performed to identify all clinical studies concerning WP validation compared with PSG as diagnostic tools. A qualitative analysis of the data was conducted. RESULTS: In this review, 18 studies were included for a total of 1049 patients, aged 8 to 70 years old, with 74 of these being pediatric patients. In most studies, patients completed an overnight PSG and simultaneously wore WatchPAT in a sleep laboratory, while others compared the results obtained on two different nights. Both protocols showed good results in terms of AHI, ODI, RDI, and SO2. Moreover, some studies calculated the sensitivity and specificity of the WP ranging from 87 to 96% and from 66 to 80%, respectively. Excellent results were found also in pediatric patients. CONCLUSION: The WP represents an effective and convenient tool for OSA diagnosis compared to standard reference systems.

BACKGROUND: Recently, the use of barbed pharyngoplasty (BP) has become widespread in snoring and obstructive sleep apnoea (OSA) palatal surgery, but there are no studies regarding the short- and long-term complications resulting from these different techniques. This systematic review aimed to report the complications and side effects of different BP techniques. METHODS: An electronic search was performed on PubMed/MEDLINE, Google Scholar, and Ovid databases. The PRISMA statement was followed. Databases were searched from inception through September 2, 2021. RESULTS: We included 14 prospective clinical studies consisting of 769 patients aged 23 to 81 years. The associated intra-operative complications of BP were as follows: partial thread extrusion (2.9%), self-limited bleeding (2.9%), broken needle (1.0%), and suture rupture (1.0%). Short-term complications were as follows: thread/knot extrusion (12.4%), dysphagia (5.6%), bleeding (1.5%), velopharyngeal insufficiency (1.5%), anterior pharyngoplasty dehiscence (1.2%), tonsillar haemorrhage (1.0%), excessive postnasal discharge (1.0%), barbed suture failure (0.5%), acute infection (0.2%), mucosal granulomas (0.2%), chipped tooth caused by mouth gag displacement (0.2%), and fibrous scar (0.2%). Long-term complications were as follows: foreign body sensation (7.8%), sticky mucus in throat (5.9%), dysphagia (3.6%), rhinolalia (3.1%), throat phlegm (1.1%), nose regurgitation (0.8%), dry throat (0.6%), and throat lump (0.3%). CONCLUSION: BP is a safe technique free of significant side effects and major complications. However, in this review, patients undergoing BP were very heterogeneous in terms of characteristics of patients chosen and severity of diseases, surgical technique used (myoresective vs non-myoresective), time of follow-up, and mono level vs multilevel surgery. More studies on a larger scale with long-term follow-up are needed to confirm these promising results.

BACKGROUND: Myringotomy with ventilation tube (VT) insertion is one the most performed procedures in children and adolescents worldwide. VTs usually remain in the eardrum between 6 and 12 months and during this period otorrhoea is the most frequent complication. For years, parents have been advised to protect the ears of children with VTs from contact with water, as water exposure in the middle ear is likely to cause acute otitis media. However, there is a growing evidence that water should not traverse VTs unless under significant pressure, so routine water precautions should not be prescribed. Despite these recommendations, many otolaryngologists and paediatricians continue to prescribe earplugs during bathing or swimming or advise against aquatic activities. There are already two reviews in the current literature on this topic: the first used strict selection criteria and included only 2 high-quality studies, while the second presented evidence up to 2005. The aim of this review is to identify, summarize and critically appraise the current evidence concerning water precautions for children with VTs. METHODS: Two independent reviewers separately searched for related scientific papers. A qualitative synthesis analysis was performed considering the selected studies regarding the effects of water exposure on paediatric subjects with VTs. RESULTS: Four randomized clinical trials (RCT) and five prospective cohort studies were included, for a total of 1299 patients aged from 3 months to 14 years. No statistically significant difference in otorrhoea incidence between water exposure with and without ear protection in children with VTs, and between water exposure and no water exposure in children with VTs, was found. Therefore avoiding water is at best inconvenient and at worst may delay learning to swim. The decision to protect the ear when exposed to water should be individualized and protection should be recommended during the first month after surgery and in cases of recurrent otorrhoea. CONCLUSION: Based on the literature available, allowing water surface activities with no ear protection seems to present a minimum risk, so it is not necessary to prohibit patients from swimming. However, some recommendations should be followed.

Transoral robotic surgery (TORS) for Obstructive Sleep Apnea (OSA) is a relatively young technique principally devised for managing apneas in the tongue base area. This study summarizes and presents our personal experience with TORS for OSA treatment, with the aim to provide information regarding its safety, efficacy, and postoperative complications. A retrospective study was conducted on patients undergoing TORS with lingual tonsillectomy through the Da Vinci robot. The effectiveness of the surgical procedure was assessed employing the Epworth Sleepiness Scale (ESS) and overnight polysomnography with the Apnea-Hypopnea Index (AHI). A total of 57 patients were included. Eighteen patients (31.6%) had undergone previous surgery. The mean time of TORS procedure was 30 min. Base of tongue (BOT) management was associated with other procedures in all patients: pharyngoplasty (94%), tonsillectomy (66%), and septoplasty (58%). At 6 months follow-up visit, there was a significant improvement in AHI values (from 38.62 ± 20.36 to 24.33 ± 19.68) and ESS values (from 14.25 ± 3.97 to 8.25 ± 3.3). The surgical success rate was achieved in 35.5% of patients. The most frequent major complication was bleeding, with the need for operative intervention in three cases (5.3%). The most common minor complications were mild dehydration and pain. TORS for OSA treatment appears to be an effective and safe procedure for adequately selected patients looking for an alternative therapy to CPAP.
RESUMO
INTRODUCTION: Oropharyngeal surgery for Obstructive Sleep Apnea (OSA) has evolved from a radical excision of "redundant" soft tissue for the enlargment of the airway to a minimally invasive reconstruction to fulfill both preservation of pharyngeal function and improvement of sleep apnea. Recently, Alianza surgical technique has been successfully introduced as a new, non-resective procedure aimed to treat concentric pharyngeal collapse at the velum using Barbed Sutures. The aim of this study was to show the effectiveness and safety of Alianza technique as standalone surgical treatment in selected patients with moderate-severe OSA and concentric pharyngeal collapse that refused or did not tolerate Continuous Positive Airway Pressure therapy. MATERIALS AND METHODS: Effectiveness of the surgical procedure was assessed by means of the Epworth Sleepiness Scale (ESS), Home Sleep Test, and a 0-10 snoring VAS. RESULTS: At the end of our selection process, 26 patients were enrolled, with a mean age of 52.7 ± 9.2 years, that undergone Alianza tecnique. There was a statistically significant reduction in mean post-operative apnea-hypopnea indexes (34.1 ± 11.5-16.3 ± 10.3; p <0.01), mean oxygen desaturation index (29.0 ± 14.5-13.1 ± 9.2; p < 0.01), and mean ESS scores (12.1 ± 5.8 and 5.8 ± 4.4; p < 0.01).There was also a significant decrease in mean post-operative snoring VAS scores (7.85 ± 1.23 vs 3.2 ± 1.7, p < 0.01). There were no major complications. CONCLUSIONS: Our preliminary results suggest that Alianza technique is a safe and repeatable surgery. Further studies on a larger scale are needed to confirm these encouraging data supporting the role of Alianza alone or in OSA multilevel surgery in selected OSA patients.

PURPOSE: The aim of the present study was to compare two clinical pathways: the multiple-access outpatient pathway versus the telemedicine pathway. METHODS: The multiple-access outpatient pathway and the telemedicine pathway were both performed with WatchPAT and implemented in a real-life healthcare scenario, adopting a cost-minimization approach. A cost-minimization analysis was undertaken to assess the economic impact of the two alternatives. The cost analyses were performed in euros for the year 2021 adopting the patient, the hospital, and the societal perspectives. Given the chosen perspectives, direct medical costs, direct nonmedical costs, and indirect costs were considered. In addition, a univariate sensitivity analysis was conducted. RESULTS: From a hospital perspective, the telemedicine approach was estimated to cost 49 more than the multiple-access alternative. Considering the patient perspective, the telemedicine approach was estimated to cost 167 less than the multiple-access pathway. Considering the societal perspective, the telemedicine approach is estimated to cost 119 less than the multiple-access pathway. CONCLUSION: The adoption of telemedicine home sleep apnea testing could improve the efficiency of the healthcare processes if considering the direct and indirect costs incurred by patients and not only by healthcare providers.
