Quality of Life and Excessive Daytime Sleepiness in Adults with Obstructive Sleep Apnea Who Are Treated with Multilevel Surgery or Adherent to Continuous Positive Airway Pressure.

Obstructive Sleep Apnea (OSA) syndrome is a respiratory sleep disorder characterized by a reduction (hypopnea) in or a complete cessation (apnea) of airflow in the upper airways at night, in the presence of breathing effort. The gold standard treatment for OSA is ventilation through continuous positive airway pressure (CPAP), although this often shows poor patient compliance. In recent years, transoral robotic surgery (TORS) has been proposed as a valid surgical treatment for patients suffering from OSA in a multilevel surgical setting. The aim of this study is to analyze the effects on QoL and daytime sleepiness of multilevel surgery for OSA (barbed pharyngoplasty + transoral robotic surgery). Furthermore, we compared the impact on QoL and daytime sleepiness of two different treatments for patients with moderate to severe OSA, such as CPAP and TORS. Sixty-seven OSA patients who underwent multilevel robotic surgery and sixty-seven OSA patients treated with CPAP were enrolled, defined as Group 1 and Group 2, respectively. The Glasgow Benefit Inventory (GBI) questionnaire was administrated to evaluate the changes in the QoL. Respiratory outcomes were evaluated and compared. Group 1 showed a GBI total average value of +30.4, whereas Group 2, a value of +33.2 (p = 0.4). General benefit score showed no difference between groups (p = 0.1). Better values of social status benefit (p = 0.0006) emerged in the CPAP Group, whereas greater physical status benefit (p = 0.04) was shown in the TORS Group. Delta-AHI (-23.7 ± 14.3 vs. -31.7 ± 15.6; p = 0.001) and Delta-ODI (-24.5 ± 9.5 vs. -29.4 ± 10.5; p = 0.001) showed better values in the CPAP group. Therapeutic success rate of the Multilevel TORS Group was 73.1% and 91% in the CPAP group (p = 0.01), respectively. Multilevel TORS and CPAP have a positive effect on the quality of life of OSA patients. Greater social support has been reported in the CPAP group and better physical health status in the TORS group. No statistical difference emerged in the reduction in daytime sleepiness between both groups.

Treatment of Benign Lesion of Levels I or II of the Parotid Gland: Long Term Results of Partial Superficial Parotidectomy.

ABSTRACT: The correct surgical approach to benign parotid gland tumors is still matter of debate, it should be chosen considering the possibility of local recurrence or facial nerve complications in case of "not necessary" facial nerve dissection. In the era of minimally invasive surgery, more sparing approaches such as extracapsular dissection or partial superficial parotidectomy (PSP) are gaining popularity. The aim of the study is to present surgical results and long-term outcomes of PSP (level i or ii) in a large group of patients. Six hundred fifty-one patients who underwent parotid surgery between 2004 and 2020 were initially considered. Five hundred forty patients with benign lesions treated with PSP, enucleation, ECD were enrolled. Clinical features, surgical data, postoperative scarring, seroma, dehiscence, neuroma, outcomes as Frey syndrome, and delayed facial nerve dysfunction have been evaluated. 65.5% PSP, 25.2% enucleation, and 9.2% extracapsular dissection. No statistical difference in surgical time has been found (P 0.16). P  > 0.05 for seroma, neuroma, Frey syndrome, and facial palsy between different type of surgery. Frey syndrome in PSP: 6/135 (4.4%) in 2004 to 2012 and 2/219 (0.9%) in 2013 to 2020. The reduction between periods is significant (P < 0.04). Recurrence: 0.8% (3/354) for PSP patients, 3.4% (5/ 136) in enucleation and 10% (5/50) in ECD (P = 0.02). Partial superficial parotidectomy can be considered a minimally invasive and quick procedure with low complication rate. Our data seem to support this statement (large case series and long-term follow-up).

Effectiveness of drug-induced sleep endoscopy in improving outcomes of barbed pharyngoplasty for obstructive sleep apnea surgery: a prospective randomized trial.

PURPOSE: To observe the effectiveness of preoperative drug-induced sleep endoscopy in improving surgical results of patients undergoing single-level barbed pharyngoplasty surgery for OSA, using a prospective randomized model. METHODS: A single-center randomized controlled trial with two prospective arms was carried out to compare functional results in patients treated with barbed reposition pharyngoplasty (BRP) surgery without a preoperative drug-induced sleep endoscopy (DISE) evaluation vs patients treated with BRP surgery performed after DISE evaluation of sites/patterns of collapse. RESULTS: We compared 50 patients who underwent BRP without a preoperative DISE evaluation (Group A) and 42 patients (Group B) treated with BRP surgery but preoperatively selected by means of a preoperative DISE. In this second group of patients, after DISE evaluation, 70% of patients were selected for single-level BRP surgery because they showed an isolated velopharyngeal collapse at the DISE evaluation, without obstruction at other upper airway levels evaluated. Both groups of patients showed a statistically significant difference between preoperative and postoperative values of AHI, ODI, and LOS (p<0.05 in all cases). Comparing Group A and Group B patients, the therapeutic success rate was found to be 60% in patients treated without preoperative DISE evaluation and 83% in patients treated with preoperative DISE (p = 0.02). CONCLUSION: DISE appears to improve the surgical results of single-level velopharyngeal surgery due to the possibility of excluding patients with obstruction of the base of the tongue, the hypopharynx, and the epiglottis/larynx.

Chronic obstructive Eustachian tube dysfunction: CT assessment with Valsalva maneuver and ETS-7 score.

Chronic obstructive Eustachian tube dysfunction (ETD) is a common disorder of the middle ear. In recent years, two main diagnostic tools have become available: Eustachian tube score (ETS-7) and computed tomography (CT) combined with Valsalva maneuver. The aim of this study is to evaluate the outcomes of ETS-7 and CT in a group of patients affected by middle ear atelectasis with a strong suspicion of ETD. Three males and nine females, affected by middle ear atelectasis with retraction of the TM were enrolled. Each patient underwent to Eustachian tube dysfunction evaluation adopting the ETS-7 score and a temporal bone CT with Valsalva maneuver. The ears analyzed at steady state were divided into 2 groups: ETS<7 group and ETS≥ 7 group. The same division was applied for the ears analyzed after the Valsalva maneuver: ETS<7 group and ETS≥ 7 group. ETs were categorized as "well defined" (WD) and "not defined" (ND). The results of the analysis of the ETS-7 score in all 24 ears showed that 42% presented ETS ≥7, while 58% had ETS <7, indicating a diagnosis of ETD. In the ETS<7 group after Valsalva, ET was visualized in 33% of patients. In the ETS≥7 group it was WD in 29% after the Valsalva manoeuver. In both groups the comparison between the visualization of the ET before and after the Valsalva manoeuver did not present a statistical difference. No correlation emerged between ET evaluation with CT scan during Valsalva maneuver and ETS-7 score. It confirms that there is not a gold standard for the study of ET dysfunction.

Barbed suture Extrusion and Exposure in palatoplasty for OSA: What does it mean?

PURPOSE: Analyze Extrusion&Exposion (E&E), its implications in the functional, anatomical results and subjective discomfort in OSA patients treated with Barbed Reposition Pharyngoplasty (BRP). MATERIALS AND METHODS: 488 patients treated with BRP or multilevel TORS. Stratafix wire was used in 230 patients, V-Loc in 258. E&E, timing and localization evaluated at follow-up. Polygraphy used to assess the impact of E&E on functional results, PPOPS questionnaire used for subjective discomfort. RESULTS: E&E in the entire group was 18,4%, with significant difference between Stratafix and V-Loc wire (p = 0,002), but not between BRP alone and multilevel surgery (p = 0,68). 28,9% of extrusion happened within the first seven days, 76,7% between seven days and two months, 5,5% after two months. Symptomatic clinical profile has been seen in 62,2%, asymptomatic one in 37,8% of patients. 35,5% of E&E were localized in tonsillar bed, 46,7% in soft palate and 20% in other sites. Mean delta-AHI of E&E patients was -15,87 ± 16.82 compared with one of those who did not have E&E was -16.34 ± 22,77 (p = 0,38). Mean PPOPS of 183 patients analyzed was 12,32 ± 4,96. Mean PPOPS of extruded group was 12,94 ± 4,68 and 11,92 ± 5,11 in not extruded one (p = 0,166). CONCLUSIONS: E&E are suture-type sensitive (V-Loc > Stratafix), reported more frequent when BRP is performed alone than BRP-TORS with no statistical significance. 76,7% of the E&E occur after patient discharge and within 2 months. About half of the E&E were localized in soft palate. There is no need to fear Extrusion&Exposition because it does not affect in a negative way subjective and PSG outcome.

Olfactory function in patients with obstructive sleep apnea: a meta-analysis study.

PURPOSE: This meta-analysis study was designed to analyze the olfactory function in obstructive sleep apnea patients (OSA). METHODS: A comprehensive review of the English language literature regarding OSA patients and olfactory function/dysfunction was performed. The papers assessing olfactory dysfunction with Sniffin' Sticks test were taken into consideration. RESULTS: A total of 420 OSA patients were judged eligible for the study. The average TDI score was found to be 24.3 ± 5.6. The olfactory identification (OD), the olfactory discrimination (OD), and the olfactory threshold (OT) average values were calculated resulting 9.9 ± 2.1, 9.8 ± 1.5, and 5.3 ± 2, respectively. There were 161 healthy control subjects in this meta-analysis. The average TDI of the control group was 30.7 ± 6.0 showing a statistical difference with the group of OSA patients (p = 0.03). A linear correlation between Apnea-Hypopnea Index (AHI) increase and TDI decrease (R2 = 0.1, p = 0.05) was detected. Finally, the average values of TDI of 151 patients classified as mild-moderate OSA and 159 patients considered as severe OSA were calculated. The difference between these two groups resulted not statistically significant (p = 0.3). CONCLUSION: The comparison between OSA patients and healthy subjects using Sniffin' Sticks test showed lower values of the various olfactory parameters. Although a linear correlation between AHI increase and olfactory dysfunction was observed, no statistical difference between mild-moderate and severe OSA patients in terms of the severity of olfactory dysfunction could be proved.

Facial Nerve Dehiscence and Cholesteatoma: A Comparison between Decades.

OBJECTIVES: To evaluate the incidence of facial canal dehiscence (FCD) and other intraoperative findings over the last 20 years as well as correlation with the Japanese Otological Society/European Academy of Otology and Neurotology classification in patients with cholesteatoma. MATERIALS AND METHODS: A total of 469 patients operated from 1998 to 2018 were selected and divided into 2 groups of 10 years each. RESULTS: Dehiscence was significantly higher in patients with a history of pathology longer than 5 years (22.7%). Higher values were observed in revision surgery, 44.4% in the first period and 41.7% in the second. The tympanic segment was the one most frequently involved, affecting 92% of patients in the first period and 97% of patients in the second. Dehiscence occurred significantly more often in patients with a semicircular canal fistula, 14.8% in the first decade and 8.8% in the second. The incidence of FCD was significantly higher in patients with primary cholesteatoma (especially in those with combined pars tensa-flaccida) than in those with a secondary acquired one, 31.5% vs 7.4% in the first period, 21.1% vs 7.4% in the second, and in those with a stage III disease, 42% in the first period, 33.3% in the second. CONCLUSION: Patients with a shorter history of cholesteatoma as well as those not previously operated had a lower incidence of FCD. The tympanic tract of the facial nerve remains the most frequent site of dehiscence, while the association between dehiscence and fistula of the semicircular canal remains strong. Patients with combined pars tensa-pars flaccida and stage III cholesteatoma have a higher incidence of FCD.

Diagnosis of Obstructive Sleep Apnea in Patients with Allergic and Non-Allergic Rhinitis.

Background and objectives: Rhinitis could be considered a risk factor for obstructive sleep apnea (OSA). Studies were conducted to evaluate the relation between OSA and Allergic rhinitis (AR). Non-allergic rhinitis with eosinophilia syndrome (NARES) is a condition with a symptomatology apparently similar to AR. The aim of this study was to evaluate the different presence of OSA in patients suffering from NARES and AR. Materials and Methods: Sixty patients were enrolled and subdivided into NARES, AR and control groups. NARES and AR diagnosis were performed using ARIA (Allergic Rhinitis and its Impact on Asthma) protocol. All patients were screened for OSA with home sleep apnea testing (HSAT) exam analyzing AHI (Apnea Hypopnea Index) values. Results: Results showed that 60% of patients affected by NARES presented OSA. On the contrary, altered AHI was found only in 35% of patients affected by AR and in 10% of patients belonging to the control group. Conclusions: In conclusion, data showed that there was an increased risk of OSA in NARES patients respect to AR patients and healthy patients.

Overview of different modified full-face snorkelling masks for intraoperative protection.

OBJECTIVE: The COVID-19 pandemic has caused significant impact on healthcare systems worldwide. The rate of infected healthcare workers is > 10% in Italy. Within this dramatic scenario, the development of new personal protective equipment (PPE) devices is mandatory. This study focuses on validation of modified full-face snorkel masks (MFFSM) as safe and protective equipment against SARS-CoV-2 infection during diagnostic and therapeutic procedures on the upper aerodigestive tract. METHODS: Five different MFFSM were tested during otolaryngological surgery and in anaesthesia procedures. Data were collected through an online survey to assess the feedback of operators. pO2 and pCO2 monitoring values during procedures were recorded in selected cases. RESULTS: All five MFFSM tested were easy to use and gave all operators a sound "feeling" of protection. All clinicians involved had common agreement regarding safety and the user-friendly format. CONCLUSIONS: In the future, specific development of different type of masks for protection in the operating room, intensive care units and/or office will be possible as a joint venture between clinicians and developers. Goals for clinicians include better definition of needs and priorities, while developers can devote their expertise to produce devices that meet medical requirements.

Facial nerve dehiscence and cholesteatoma: Pediatrics vs adults.

OBJECTIVES: the aim of this paper is to study the incidence of facial canal dehiscence (FCD) in pediatric and non-pediatric patients, analyzing eventual differences in frequency, localization, primary or revision surgery and duration of the disease. METHODS: 527 patients suffering from chronic otitis media with acquired cholesteatoma, divided into two groups, those aged 18 years or over (470 patients), and those aged below 18 years (57 patients). RESULTS: Total incidence of FCD in adult population was 25,7% (121/470) and 7% (4/57) in pediatric one. Globally higher values were found in revision surgery, 43,5% (40/92) in adults and 16,7% (1/7) in children. Diseases longer than 5 years have been correlated to higher incidence of FCD in adults, 29,9% (109/364), than in pediatrics, 7,3% (3/41). No statistical significant difference has been found in those with a disease shorter than 5 years: 11,3% in adults (12/106) and 6,2% in children (1/16). The majority of patients, both adults and pediatrics, had a dehiscence in the tympanic tract of facial nerve. No statistical correlation regarding concomitant semicircular canal fistula and FCD has been found due to the absence of data in children. CONCLUSIONS: Incidence of FCD is higher in adult population than in pediatric. Adults have a higher incidence in primary surgery than children. No statistical significant difference has been found in adults and pediatrics with a less than 5 years disease, while diseases longer than 5 years expose adults to higher risk of FCD. Middle tract of tympanic segment is the most involved site of dehiscence in both populations.

Risk Factors for Obstructive Sleep Apnea Syndrome in Children: State of the Art.

The obstructive sleep apnea syndrome (OSAS) represents only part of a large group of pathologies of variable entity called respiratory sleep disorders (RSD) which include simple snoring and increased upper airway resistance syndrome (UARS). Although the etiopathogenesis of adult OSAS is well known, many aspects of this syndrome in children are still debated. Its prevalence is about 2% in children from 2 to 8 years of age, mostly related to the size of the upper airways adenoid tissue. Several risk factors linked to the development of OSAS are typical of the pediatric age. The object of this paper is to analyze the state of the art on this specific topic, discussing its implications in terms of diagnosis and management.

Aging effect on sleepiness and apneas severity in patients with obstructive sleep apnea syndrome: a meta-analysis study.

PURPOSE: Different authors have reported that aging could be associated with changes in obstructive sleep apnea (OSA) related parameters (apnea/hypopnea index, SpO2, reduction of daytime sleepiness, etc.), type of sleep and pattern of collapse. Regarding OSA severity in elderly patients, it is commonly believed that the AHI score tends to increase with aging. METHODS: In this paper, we reviewed the literature regarding the studies which compared older (> 65 years old) and young (< 65 years old) OSA patients regarding the effect of aging on daytime sleepiness (ESS evaluation) and OSA severity (AHI evaluation). A meta-analysis to evaluate the effect of age on daytime sleepiness and OSAS severity was also performed to corroborate previously reported experience. RESULTS: Meta-analysis showed no statistical (p = 0.8) differences regarding AHI differences emerged from the comparison of the two groups of patients. Elderly patients (> 65 years old) showed less daytime sleepiness, showing a statistical difference in the meta-analysis of data (p = 0.004) CONCLUSION: Although a direct correlation between aging and AHI values would seem to be present, no significant differences in baseline AHI between young (< 65-years-old) and elderly (> 65-years-old) patients emerged in this meta-analysis study. The effects of OSAS on daytime sleepiness seem to be much more prominent in young or middle-aged patients than in elderly patients.

Giant Cell Arteritis (GCA): Pathogenesis, Clinical Aspects and Treatment Approaches.

Giant Cell Arteritis (GCA), or Horton's Arteritis, is a chronic form of vasculitis of the large and medium vessels, especially involving the extracranial branches of the carotid arteries, in particular, the temporal artery, with the involvement of the axillary, femoral and iliac arteries too. Arterial wall inflammation leads to luminal occlusion and tissue ischemia, which is responsible for the clinical manifestations of the disease. A substantial number of patients affected by GCA present head and neck symptoms, including ocular, neurological and otorhinolaryngological manifestations. The aim of this article is to present pathogenesis, clinical aspects and treatment approaches of GCA manifestations.

Laryngopharyngeal reflux in obstructive sleep apnoea patients: Literature review and meta-analysis.

PURPOSE: Laryngopharyngeal reflux (LPR) is a frequent condition in Obstructive Sleep Apnoea (OSA) patients and different studies have been published in the last years about this topic. A review of the published literature regarding LPR in OSA patients has been reported. A meta-analysis to evaluate the incidence of LPR in OSA patients and correlate LPR positivity with OSA patients' characteristics has been performed. METHODS: A comprehensive review of the English language literature about LPR in OSA patients was performed using the most important electronic databases (PubMed, EMBASE, the Cochrane Library etc.). A total of 10 papers studying LPR in OSA were assessed and considered eligible for the meta-analysis. RESULTS: The data analysis regarding 870 identified OSA patients showed that 394 patients were LPR +, while 476 were LPR-. The meta-analysis showed no statistical difference regarding the AHI value between LPR + patients and LPR- patients (p = 0,3). Mean BMI was more higher in LPR + patients than in the patients without LPR, showing a significant statistical difference (p = 0.001). CONCLUSION: Current international literature demonstrates a high incidence of LPR (45.2%) in OSA patients. The severity of AHI in OSA patients would not seem to correlate with the presence of laryngopharyngeal reflux. The OSA patients with LPR showed a higher BMI compared with LPR- patients.

Chronic inflammatory demyelinating polyneuropathy: evaluation of the vestibular system with cervical and ocular vestibular evoked myogenic potentials.

PURPOSE: To investigate the possibility of vestibular damage in a group of patients suffering from chronic inflammatory demyelinating polyneuropathy (CIDP) using a diagnostic protocol including the caloric test, C-VEMPs and O-VEMPs. METHODS: Twenty patients suffering from CIDP (mean age 58.5 years, range 33-80 years; 4 women and 16 men) were investigated. To assess any eventual audio-vestibular involvement, all patients of the study underwent pure tone audiometry, Fitzgerald-Hallpike caloric vestibular test, C-VEMPs and O-VEMPs. RESULTS: In 11 patients with CIDP values of both O-VEMPs and C-VEMPs were either absent or abnormal. An absent trace at O-VEMPs testing occurred in 36% of these pathological patients, whereas an increase of n10 latency and amplitude was present in the other 64% . CONCLUSIONS: A specific diagnostic protocol including the caloric test, C-VEMPS, O-VEMPS, could be useful when employed for identifying vestibular damage in CIDP patients.

Eustachian tube evaluation in patients with obstructive sleep apnea syndrome.

OBJECTIVES: Investigate the presence of Eustachian Tube Dysfunction (ETD) in Obstructive sleep apnea (OSA) patients. Correlate the ET function and the severity of the sleep apnea syndrome. Correlate nasal resistance and nasal mucociliary clearance with the onset of ETD in these patients. MATERIALS AND METHODS: Forty patients affected by OSA were enrolled in our clinical prospective study. Thirty patients were also investigated as a control group. All of the analyzed subjects underwent ENT examination, anterior rhinomanometry and test for mucociliary transport time. To evaluate Eustachian tube function the Eustachian tube score-7 (ETS-7) were employed. RESULTS: Twenty percent of the patients with a diagnosis of OSA had a diagnosis of ETD (ETS-7 ≤ 7) with a statistical difference with control group (p = .03). No differences regarding ETD in OSA sub-groups were found. CONCLUSION: This study showed that ET blockage or delayed openings were found in most adult patients with OSA when evaluated by a sensible score as the ETS-7. Our data suggest that an evaluation of the Eustachian tube function should be performed in patients suffering from obstructive sleep apnea syndrome.
