Laryngomalacia and Obstructive Sleep Apnea in Children: From Diagnosis to Treatment.

The aim of this review is to investigate the state of the art among the association between Obstructive sleep apnea (OSA) and laryngomalacia, analyzing the epidemiology, the diagnostic tools, and the possible treatments available to affected patients. Laryngomalacia, characterized by the malacic consistency of the epiglottis with a tendency to collapse during inspiratory acts, producing a characteristic noise known as stridor, is a common condition in infants and particularly in those affected by prematurity, genetic diseases, craniofacial anomalies, and neurological problems. Congenital laryngomalacia, presenting with stridor within the first 15 days of life, is often self-limiting and tends to resolve by 24 months. OSA is not only a consequence of laryngomalacia but also exacerbates and perpetuates the condition. Currently, the treatments reported in the literature are based (i) on medical therapies (including watchful waiting) and (ii) on surgical treatments. Among the surgical techniques, the most described is supraglottoplasty, performed with the use of cold instruments, CO2 LASER, transoral robotic surgery, or the microdebrider.

Oncological features and outcomes of laryngeal cancer surgery: a multicentric study.

BACKGROUND: Laryngeal cancer (LC) is among of the most frequent head and neck cancers, associated to a high social impact and mortality. Unfortunately, the current treatment outcomes of LC are often scant, with different factors affecting patient's prognosis (i.e., advanced age, advanced disease stage, lymph node involvement, tumor pathological features, type of intervention). The aims of the present study were: 1) to evaluate the epidemiological and clinical features of patients affected by LC; and 2) to focus on tumor risk factors affecting patient's overall survival (OS) and recurrences. METHODS: A retrospective analysis of all patients affected by LC and surgically treated at two different hospital settings has been performed. RESULTS: Two hundred twenty-five patients were enrolled in the present study; of these 189 were males (84%) and 36 (16%) were females. The most frequently performed surgery was total laryngectomy. Thirty-two (14.2%) patients experienced local recurrence, while 15 patients (6.6%) had regional recurrence and 15 distant metastases. Multivariate analysis showed that locoregional recurrence was associated to the occurrence of distant metastases (P=0.002, HR=25,35). Analyzing OS, the only statistically significant factor that correlated with an increased risk of mortality (P<0.015, HR=2,45) was locoregional recurrence. CONCLUSIONS: The present study confirms the literature data about age and sex distribution of LC, about tumors localization, lymph nodes metastasis and distant metastasis incidence and OS rate, based on T and N stage. Interestingly, within this series, the presence of locoregional recurrence or distant metastasis is related to a worst prognosis and a lower overall survival rate.

Clear-Cell Renal Cell Carcinoma Metastasis into Pterygomaxillary Fossa - A Case Report.

Rationale: The aim of this study is to describe a rare case of clear-cell renal cell carcinoma (ccRCC) metastasis to the pterygomaxillary fossa. Patient Concerns: A 54-year-old woman was referred to the Department of Otolaryngology due to right facial pain for the past six weeks. Diagnosis: ccRCC metastasis to the pterygomaxillary fossa. Treatment: The patient was treated by immunotherapy (Ipilimumab + Nivolumab) after multidisciplinary team evaluation. Outcomes: After 18 months, the patient is in good overall condition and the size of the skull base lesion has significantly reduced. Take-Away Lessons: ccRCC metastasis to the skull base and adjacent sites occur rarely. Most commonly, the presenting symptoms of these lesions are headache and diplopia for skull base metastases and epistaxis in case of sinusal involvement, according to the literature. When total resection of the metastasis is not feasible, tumour-targeted therapy may be used, as in the presented case. A multidisciplinary evaluation is recommended for the correct assessment and management of these patients.

Basal cell adenoma and pleomorphic adenoma of the parotid gland: a single center experience.

BACKGROUND: Basal cell adenoma (BCA) and pleomorphic adenoma (PA) are among the most common benign neoplasms of the salivary glands. The aim of this study was to analyze and compare the diagnosis, treatment, and recurrence rate of these two different types of parotid benign tumors. METHODS: A retrospective analysis of all cases of parotid gland BCA and PA surgically treated between January 1, 1990, and December 31, 2019, was performed at our university. RESULTS: A total of 349 patients were enrolled in the present study, 311 of which (89.1%) were affected by PA, and 38 patients (10.9%) by BCA. The most frequently performed surgery was partial parotidectomy for both groups (85.9% in PA and 65.8% in BCA). Perioperative complications - often transient and of short duration - occurred within 48 hours of surgery and were observed in 30.6% of PA patients and in 18.4% of BCA patients; furthermore, recurrences were noticed in 19 PA patients (6.2%) and in 3 BCA patients (7.9%) (rates in range with the available literature data). CONCLUSIONS: To the best of our knowledge, this study is one of the largest single-center series in the literature comparing diagnosis, treatment, recurrence rate and clinical-pathological features of two different types of benign parotid gland tumors, BCA, and PA.

Hearing Loss and Blood Coagulation Disorders: A Review.

A relationship between microvascular disorders and sensorineural hearing loss (SNHL) has been widely proposed. The vascular hypothesis, theorized for the onset of sudden SNHL (SSNHL), is among the most acknowledged: a localized acute cochlear damage, of ischemic or haemorrhagic nature, could be considered a causative factor of SSNHL. The aim of this review is to assess (i) the effect on hearing in patients affected by blood coagulation disorders (prothrombotic or haemorrhagic) and (ii) the possible etiopathogenetic mechanisms of the related hearing loss. A PRISMA-compliant review was performed. Medline, Embase, and Cinahl databases were searched from inception to 31 January 2023, and a total of 14 studies have been included in the review. The available data suggest that it is possible to consider clotting disorders as a potential condition at risk for sensorineural hearing loss; in particular, coagulation tests and eventually the assessment of genetic and acquired prothrombotic factors should be recommended in patients with SSNHL. Also, an audiological evaluation should be recommended for patients with blood coagulation disorders presenting cochlear symptoms, especially in those suffering from clotting diseases.

Reconstructive Options after Oncological Rhinectomy: State of the Art.

BACKGROUND: The nose is a central component of the face, and it is fundamental to an individual's recognition and attractiveness. The aim of this study is to present a review of the last twenty years literature on reconstructive techniques after oncological rhinectomy. METHODS: Literature searches were conducted in the databases PubMed, Scopus, Medline and Google Scholar. "Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA)" for scoping review was followed. RESULTS: Seventeen articles regarding total rhinectomy reconstruction were finally identified in the English literature, with a total of 447 cases. The prostheses were the reconstructive choice in 213 (47.7%) patients, followed by local flaps in 172 (38.5%) and free flaps in 62 (13.8%). The forehead flap (FF) and the radial forearm free flap (RFFF) are the most frequently used flaps. CONCLUSIONS: This study shows that both prosthetic and surgical reconstruction are very suitable solutions in terms of surgical and aesthetic outcomes for the patient.

Cerebral Outflow Discrepancies in Recurrent Benign Paroxysmal Positional Vertigo: Focus on Ultrasonographic Examination.

This prospective pilot study aimed to evaluate whether cerebral inflow and outflow abnormalities assessed by ultrasonographic examination could be associated with recurrent benign paroxysmal positional vertigo (BPPV). Twenty-four patients with recurrent BPPV, affected by at least two episodes, and diagnosed according to American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) criteria, evaluated at our University Hospital, between 1 February 2020 and 30 November 2021, have been included. At the ultrasonographic examination, 22 of 24 patients (92%) reported one or more alterations of the extracranial venous circulation, among those considered for the diagnosis of chronic cerebrospinal venous insufficiency (CCSVI), although none of the studied patients were found to have alterations in the arterial circulation. The present study confirms the presence of alterations of the extracranial venous circulation in recurrent BPPV; these anomalies (such as stenosis, blockages or regurgitation of flow, or abnormal valves, as per the CCSVI) could cause a disruption in the venous inner ear drainage, hampering the inner ear microcirculation and then possibly causing recurrent otolith detachment.

Role of 18F-FDG PET/CT in evaluating lymph node status in patients with head and neck squamous cell carcinoma.

Objective: The presence of cervical lymph node metastases (CLNM) at diagnosis is one of the most relevant negative prognostic factors in patients with head and neck squamous cell carcinoma (HNSCC). The aim of this study was to analyse 2-deoxy-2[18F]fluoro-D-glucose (FDG) PET/CT findings for the identification of primary tumours and CLNM in a sample of patients affected by HNSCC. Moreover, a maximum standardised uptake value (SUVmax) threshold for the detection of CLNM was estimated. Clinical variables (i.e. smoking and alcohol habits), and tumour features (i.e. EBV and HPV positivity) were also evaluated in relation to FDG PET/CT findings. Methods: We retrospectively analysed patients who underwent FDG PET/CT for HNSCC staging between 2015-2020 at the University Hospital of Ferrara. All patients had cytological or histological confirmation of suspected cervical lymph nodes. Results: In total, 65 patients were enrolled (53 males, 12 females, median age 65.7 years). CLNM of patients with smoking habit had significantly higher SUVmax values than those of patients with previous smoking habit and non-smokers (p = 0.04). p16 positive HNSCC demonstrated a trend for higher SUVmax values on CLNM, in comparison to p16 negative tumours (p = 0.089). ROC curve analysis identified 5.8 as the best cut-off value of SUVmax for the detection of CLNM (AUC = 0.62, sensitivity 71.4% and specificity 72.7%). Conclusions: FDG PET/CT is a useful tool to evaluate CLNM in patients with HNSCC, particularly in those with smoking habit and p16 positive disease. A SUVmax cut-off of 5.8, combined with the use of conventional radiological investigations, may represent a useful tool in the identification of CLNM.

Wait and Scan Management of Intra-canalicular Vestibular Schwannomas: Analysis of Growth and Hearing Outcome.

OBJECTIVE: To report on the results of intracanalicular vestibular schwannomas (ICVS) that were managed by wait and scan and to analyze the possible predictors of tumor growth and hearing deterioration throughout the observation period. STUDY DESIGN: A retrospective case series. SETTING: Quaternary referral center for skull base pathologies. PATIENTS: Patients with sporadic ICVS managed by wait and scan. INTERVENTION: Serial resonance imaging (MRI) with size measurement and serial audiological evaluation. MAIN OUTCOME MEASURE: Tumor growth defined as 2 mm increase of maximal tumor diameter, further treatment, and hearing preservation either maintain initial modified Sanna hearing class, or maintain initial serviceable hearing (class A/B). RESULTS: 339 patients were enrolled. The mean follow-up was 36.5±31.7 months with a median of 24 months. Tumor growth occurred in 141 patients (40.6%) either as slow growth (SG) in 26.3% of cases or fast growth (FG) in 15.3% of cases. Intervention was performed in only 64 cases (18.8%). Out of 271 patients who underwent hearing analysis, 86 patients (33.5%) showed hearing deterioration to a lower hearing class of the modified Sanna classification. Tumor growth and older age were predictors of hearing deterioration. Of the 125 cases with initial serviceable hearing (Class A/B), 91 cases (72.8%) maintained serviceable hearing at last follow-up. Tumor growth and a worse initial pure tone average (PTA) were predictors of hearing deterioration. CONCLUSIONS: Wait and scan management of ICVS is a viable option and only 18.8% of patients needed further treatment. Hearing tends to deteriorate over time.

Sleep position and obstructive sleep apnea (OSA): Do we know how we sleep? A new explorative sleeping questionnaire.

PURPOSE: Positional obstructive sleep apnea (POSA) has been defined as a difference of 50% or more in Apnea-Hypopnea Index (AHI) between supine and non-supine position. Sleep position is fundamental in the evaluation of obstructive sleep apnea syndrome (OSAS) severity but most tools used in the diagnosis of OSAS are not free from potential bias in the evaluation of usual sleep positions. The aim of this investigation was to evaluate a novel sleep questionnaire with the purpose of exploring sleep habits and evaluating if sleep assessment can identify the usual body position assumed for sleep. MATERIALS AND METHODS: The questionnaire was administered to patients recruited from October to November 2018. Questions concerned sleeping positions and conditions that could influence sleeping positions. Patients who had previously undergone polysomnography (PSG) were asked how they slept during the study night. Whenever present during the examination, the patient's bed partner was also asked about the patient's usual body positions during sleep. RESULTS: Of 315 patients (211 men) enrolled, 35% were affected by OSAS and 69% of patients with OSAS had POSA. POSA was more prevalent among men (75%) compared to women (43%). The new questionnaire provided a discordant result from PSG recordings about sleeping positions and revealed a difference between usual sleeping position and the position during PSG recording. Reported sleep quality was much worse on PSG than at home suggesting that the "first night effect" is real and may lead to over-estimation of POSA cases. CONCLUSIONS: Information about sleeping positions is fundamental to the assessment of OSAS severity. Knowledge gained from the new questionnaire as described may represent a valuable addendum to develop a more detailed polygraphic report. Such a tool may be used in practice with the aim of better identifying patients with true positional OSAS. Such patients may benefit from targeted positional therapy.

Thymic Epithelial Tumors: Prognostic Significance and Relationship between Histology and the New TNM Staging System.

BACKGROUND: This study aims to describe the relationship between the new tumor nodes metastasis (TNM) staging and World Health Organization (WHO) classification and to identify how these two variables relate to each other and whether they possess a prognostic value in predicting survival and recurrence of disease. METHODS: Medical records of 54 patients who underwent surgery for thymic epithelial tumors between 1996 and 2015 were reviewed.The histologic type of neoplasm was classified according to the criteria of WHO and staging was evaluated using the new TNM classification system. RESULTS: A significant correlation between the TNM stages and the histological classification was found (p < 0.001). Complete resection is related to both TNM stage and histological grading (p < 0.001). Evaluation of the 5- and 10-year survival curves shows how these are significantly correlated only at the stage (p = 0.03 and = 0.04, respectively). The risk of death at 5 and 10 years for stages III to IV is six and three times higher than in stages I to II, respectively. Regarding the disease-free survival, there is significant correlation with both staging and histology (p = 0.001 and = 0.02, respectively). CONCLUSIONS: There is a significant correlation between the new TNM staging and the histological grade WHO. The ability to implement a complete resection, the overall and disease-free survival is closely related to the thymoma stage. Furthermore, both histotype and stage correlate with disease-free survival. In fact, the least aggressive stages, both WHO and TNM, have a free time out of disease superior to advanced stages.
