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.

Acute mastoiditis in cochlear implanted children: A single-centre experience.

BACKGROUND: Acute mastoiditis (AM) is the most common complication of acute otitis media and primarily affects children under the age of two; current data on its prevalence in paediatric patients with cochlear implant (CI) are still scant. Proper management of AM in CI children is crucial in order to avoid the implications (financial and emotional) of an explant. Aim of this paper is to describe the cases of AM occurred among young patients with CI in follow up at our department, also in order to evaluate its prevalence, potential predisposing factors, clinical course and therapeutic strategies. PATIENTS AND METHODS: Retrospective study. Medical records of all paediatric patients with CI, who had at least one year of follow-up, were searched aiming to identify those who developed AM, from January 1st 2002 to January 31st 2022. The following data were collected and analysed: demographic features, implant type and side, interval between CI surgery and AM, treatment, laboratory tests, clinical course, vaccination history, associated diseases. RESULTS: AM was developed by six (1.3%) of the 439 children with CI (541 implanted ears). In total, 9 episodes (2.05 %) were recorded, as three patients reported two consecutive infections. Average time interval between CI surgery, to the first or only AM diagnosis, was 13.8 months (range 3-30 months). Furthermore, 3/6 of patients had a history of recurrent acute otitis media; 2/6 an autism spectrum disorder, associated to a combined immune deficiency in one case. All patients were hospitalized and promptly treated by intravenous antibiotic therapy; 4/6 also underwent a mastoidectomy. CI was not explanted in any cases of this series. CONCLUSIONS: Over a 20-year period, AM rate in CI children was 1.3%, which is consistent with the current literature rates of 1-4.7%. All cases were successfully treated, preserving the integrity of the device. In our experience, the early parenteral antibiotic therapy and, when necessary, surgical treatment were adequate to eradicate the infection.

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.

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.

Lymphoscintigraphy and radio-guided neck dissection in oral cavity squamous cell carcinoma.

PURPOSE: The development of erratic distribution of cervical metastases from oral cavity squamous cell carcinoma (OSCC) bypassing the typical metastatic pattern can possibly challenge the role of the classic neck dissection. The purpose of this study was to assess the role of lymphoscintigraphy (LS) and radio-guided neck dissection as a simple and widely accessible method with a favorable cost/benefit ratio, able to improve the OSCC staging and possibly to tailor the surgical approach to cervical lymph node dissection. METHODS: From June 2015 to December 2018, 16 patients (5 women, 11 men, median age 59.5±12.5 years) with cN0 (10) and cN+ (6) OSCC were enrolled. The day before surgery all patients underwent LS with acquisition of planar and SPECT (Single Photon Emission Computed Tomography)/CT images, after a peritumoral injection of 99mTc-Nanocoll® (median 74±1.2 MBq). Patients underwent tumor excision and a radioguided neck dissection, using a portable gamma camera. The sentinel lymph nodes (SLNs) were isolated and separately analyzed in 200-micron sections and pancytokeratin immunohistochemistry assessment, looking for micrometastases. RESULTS: A homolateral lymphatic spread on LS was observed in all cases, whereas in 5 cases (31.3%) lymphatic drainage was contralateral to the OSCC site. In one cN0 patient, a skip micrometastasis has been identified in a SLN. CONCLUSION: The results of the present study may suggest a role of LS and radioguided neck dissection in detecting the real lymphatic spread of OSCC, in order to improve the oncological assessment and to tailor the neck dissection.

High Human Papillomavirus DNA loads in Inflammatory Middle Ear Diseases.

Background. Previous studies reported human papillomaviruses (HPVs) in middle ear tumors, whereas these viruses have been poorly investigated in chronic inflammatory middle ear diseases. We investigated HPVs in non-tumor middle ear diseases, including chronic otitis media (COM). Methods. COM specimens (n = 52), including chronic suppurative otitis media (CSOM) (n =38) and cholesteatoma (COMC) (n = 14), as well as normal middle ear (NME) specimens (n = 56) were analyzed. HPV sequences and DNA loads were analyzed by quantitative-PCR. HPV genotyping was performed by direct sequencing. Results. HPV DNA was detected in 23% (12/52) of COM and in 30.4% (17/56) of NME (p > 0.05). Specifically, HPV DNA sequences were found in 26.3% (10/38) of CSOM and in 14.3% (2/14) of COMC (p > 0.05). Interestingly, the HPV DNA load was higher in COMC (mean 7.47 copy/cell) than in CSOM (mean 1.02 copy/cell) and NME (mean 1.18 copy/cell) (P = 0.03 and P = 0.017 versus CSOM and NME, respectively). HPV16 and HPV18 were the main genotypes detected in COMC, CSOM and NME. Conclusions. These data suggest that HPV may infect the middle ear mucosa, whereas HPV-positive COMCs are associated with higher viral DNA loads as compared to NME.

Acquired Nasopharyngeal Stenosis Correction Using a Modified Palatal Flaps Technique in Obstructive Sleep Apnea (OSA) Patients.

Background: Acquired nasopharyngeal stenosis is a rare and heterogeneous pathological condition that has different causes, generally resulting as a complication of a pharyngeal surgery, especially in patients affected by obstructive sleep apnea (OSA). Different approaches have been proposed for the treatment of nasopharyngeal stenosis but a unique and standardized management has not yet been presented. The aim of our paper is to evaluate the efficacy of our surgical technique, describing its steps and results with the aim to consider it as a possible solution for the treatment of this condition. Methods: This is a retrospective cohort study. Eight patients (mean age 27.25 years old (yo), range 8-67 yo; Male/Female ratio 4/4; mean body mass index (BMI) 26.1) affected by OSA (mean apnea hypopnea index (AHI) before OSA surgery was 22.1) and acquired nasopharyngeal stenosis as a consequence of different pharyngeal surgeries were treated with our modified approach in the Department of Otolaryngology, Morgagni Pierantoni Hospital, Forlì, Italy. Resolution of stenosis and complication rate were the main outcome measures. Results: Complete resolution of the stenosis was achieved in all cases and no complications were recorded at three weeks, six months, and 2 years follow-up. Conclusions: Our technique appears to be a promising method for the management of nasopharyngeal stenosis in OSA patients. However, further studies comparing different techniques and reporting on larger series and longer follow up time are needed to prove the efficacy of the proposed technique.

Unilateral Sinus Disease: Not Just Odontogenic! - A Retrospective Study.

INTRODUCTION: Unilateral sinus disease (USD), and especially unilateral maxillary sinusitis (UMS), is an increasingly common finding in the ear, nose, and throat and maxillofacial practice. The aim of this retrospective study was to describe the clinical features of a series of patients affected by USD and, in particular, UMS due to sinonasal anatomic anomalies and of odontogenic origin. MATERIALS AND METHODS: A total of 292 patients affected by UMS were reviewed. Medical charts, radiological images, and surgical notes were all reviewed, particularly including data on UMS due to sinonasal anatomic anomalies and on UMS of odontogenic origin. RESULTS: A total of 66 patients have been excluded due to a diagnosis of malignant disease or other benign-defined etiology. Forty-eight patients (21.2%) affected by UMS due to sinonasal anatomic anomalies, whereas 178 (78.8%) patients affected by an odontogenic sinusitis. All patients were surgically treated by functional endoscopic sinus surgery, often in combination with a maxillofacial approach. DISCUSSION: UMS of odontogenic origin represented the greater group of USD. Computed tomography scans are always recommended to define UMS etiology (in particular excluding a malignant origin) and also to plan the most adequate surgical treatment.

Lingual tonsil lymphatic tissue regrowth in patients undergoing transoral robotic surgery.

OBJECTIVES/HYPOTHESIS: To evaluate a possible regrowth of lingual tonsil lymphatic tissue in patients submitted to lingual tonsil resection with transoral robotic surgery (TORS). STUDY DESIGN: Retrospective Study. METHODS: Medical records of patients surgically treated by means of TORS to remove excessive lymphatic tissue of the lingual tonsil were retrospectively reviewed. Postoperative endoscopic data after long-term follow-up were analyzed to investigate possible lymphatic tissue regrowth. Preoperative and postoperative lingual tonsil lymphatic tissue were classified according to the standardized Friedman's grading scale ranging from 0 to 4. RESULTS: Sixty-eight patients (41 male and 27 female; mean age = 51.3 years) were considered suitable for the study analysis. Clinical regrowth was observed in six (8.8%) patients: four (5.9%) and two (2.9%) patients with grade 2 and 3 lymphatic hypertrophy, respectively. No correlation between the grade of regrowth, the time interval from surgery, and the volume of lymphatic tissue removed was found. CONCLUSIONS: The lymphatic tissue regrowth after TORS resection appears to be very low. LEVEL OF EVIDENCE: 4 Laryngoscope, 129:2652-2657, 2019.

Pain in head and neck cancer patients: the role of gender.

PURPOSE: To assess the quality of life (QoL) following palliative radiotherapy (RT) in patients with painful bone metastases. METHODS: A literature search limited to English-written publications was carried out, through the Cochrane Central Register of Controlled Trials (November 2018), OvidSP and PubMedCentral (1940-November 2018) databases. Subject headings and keywords included "quality of life"(QoL), "bone metastases", "palliative therapy", "pain" and "radiotherapy". Original articles, literature reviews, trials and meta-analyses revealing alterations in QoL post-RT using ratified measuring tools were examined. Studies referring to other types of metastases (e.g. brain metastases), or to other types of palliative therapy (e.g. the use of bisphosphonates alone), or focusing only on pain, or even reporting QoL only before or only after the use of RT were excluded. RESULTS: Twenty four articles were selected from a total of 1360 articles. Seven trials proceeded to patients' randomization. The most commonly used tool to evaluate QoL was EORTC, followed by Brief Pain Inventory (BPI) and Edmonton Symptom Assessment System (ESAS) questionnaires. All studies showed improvement in symptoms and functional interference scores after RT. The QoL between responders (Rs) and non-responders (NRs) has been juxtaposed in 10 studies. Rs had a significant benefit in QoL in comparison with the NRs. DISCUSSION: Palliative radiotherapy in painful bone metastases improves Rs' QoL.

The aging effect on upper airways collapse of patients with obstructive sleep apnea syndrome.

PURPOSE: To evaluate, using drug-induced sleep endoscopy (DISE), sites of upper airway obstruction and pattern of collapse in patients over 65 years old affected by obstructive sleep apnea. To compare sites and pattern of collapse of elderly patients with a group of patients younger than 65 years. METHODS: A group of 55 patients aged over 65 years were enrolled in this prospective study. Fifty patients under 65 years old were collected in the control group. Polysomnographic data and clinical parameters such as the daytime sleepiness, and body mass index were evaluated for both groups of patients. All patients underwent DISE examination with VOTE classification. RESULTS: The AHI value increased with aging whereas elderly patients presented a reduction in daytime sleepiness. Elderly patients showed a higher incidence of total collapse in the velum region compared to younger patients (90.9% vs 70%;); the older patients showed a lower degree of total oropharyngeal lateral wall collapse with respect to younger patients, (20% vs 50%). No difference in tongue base collapse emerged between the two subgroups of patients. CONCLUSION: Elderly patients showed a higher incidence of total collapse in the velum and a lower incidence in the oropharyngeal lateral wall compared to younger patients.

Trans-Oral Robotic Tongue Reduction for OSA: Does Lingual Anatomy Influence the Surgical Outcome?

STUDY OBJECTIVES: To evaluate both the influence of the volume of the excised base of tongue (BOT) on the surgical outcome after robotic tongue reduction in patients affected by obstructive sleep apnea (OSA) and the role of the lymphatic or muscular predominance within the removed tissue. METHODS: Fifty-one patients with OSA were included in this study. All patients were treated with a robotic tongue base reduction. Data registered for the analysis were: age, sex, preoperative body mass index, preoperative and postoperative apnea-hypopnea index (AHI), delta AHI (preoperative AHI - postoperative AHI), total volume of the excised BOT, total thickness of excised BOT, isolated lymphatic thickness and soft tissue thickness (including muscular component) of the excised BOT, and lymphatic/soft tissue ratio (lymphatic thickness / soft tissue thickness). RESULTS: A statistically significant reduction of AHI values was seen postoperatively, and a success rate of 74.5% was recorded. However, no significant correlations between delta AHI and tongue volume in cubic centimeters, lymphatic/soft tissue ratio, and total thickness were found. CONCLUSIONS: These findings reinforce the general opinion that OSA is not only influenced by anatomic factors but other phenomena may play a fundamental role in its genesis. A deeper understanding of OSA pathogenesis is needed in order to tailor an individual treatment strategy that could lead to a more effective therapy.

Metastasis to parotid gland from non Head and Neck tumors.

PURPOSE: Most primary tumors spreading metastasis to the parotid gland are usually located in the head and neck region, nonetheless, rarely, parotid gland can also be the target of metastatic localization site of distant primary tumors. The purpose of this study was to describe a clinical series of metastasis to the parotid gland from distant primary tumors (non Head & Neck). METHODS: The clinical databases of parotid tumors in two academic centers have been analyzed and 11 cases of parotid metastatic cancers from distant primary tumors were found. RESULTS: Primary tumor was lung cancer in 8 cases, and breast cancer, gastric carcinoma and pancreatic carcinoma in one case each. CONCLUSIONS: Parotid metastases can be the first clinical manifestation of a malignant tumor from a distant site and can manifest years after curative-intent treatment of the distant primary. Histopathology and immunohistochemistry can help in the identification of the primary site. Parotidectomy with complete excision of the parotid lesion may have diagnostic and/or loco-regional control and/or curative intent, however there is still no international consensus about the therapy of parotid malignant metastasis.

Evolution of soft palate surgery techniques for obstructive sleep apnea patients: A comparative study for single-level palatal surgeries.

OBJECTIVES: To compare the results of tissue preservation techniques of soft palate surgeries including expansion sphincter pharyngoplasty (ESP) and barbed reposition pharyngoplasty (BRP) for patients suffering from obstructive sleep apnoea (OSA) with the traditional uvulopalatopharyngoplasty (UPPP). DESIGN: Interventional comparative study. SETTING: Morgagni-Pierantoni Hospital. PARTICIPANTS: Seventy-five patients were included in the study, divided into three groups with 25 patients per group: UPPP, ESP or BRP. MAIN OUTCOMES MEASURES: Polysomnography was carried out for all patients pre- and postoperatively; the postoperative results were recorded at least 6 months after surgery. All patients were assessed preoperatively using drug-induced sleep endoscopy. Epworth Sleepiness Scale and body mass index (BMI) were registered for all patients before and after surgery. RESULTS: The mean of pre- and postoperative differences of apnoea-hypopnoea index values was higher in BRP group than ESP: 15.76 ± 14.5 Vs 10.13 ± 5.3; P < .05 and UPPP groups: 15.76 ± 14.5 vs 6.08 ± 5.5; P < .0005. The mean of differences of oxygen desaturation index values was higher in BRP group than UPPP group: 15.09 ± 17.6 vs 7.13 ± 6.8; P < .0005, but not significantly higher than ESP group: 15.09 ± 17.6 vs 6.48 ± 7.9; P > .05. The mean of differences of ESS values was higher in BRP group than ESP group: 5.52 ± 4.1 vs 4.84 ± 3.3; P < .005 and UPPP groups: 5.52 ± 4.1 vs 1.36 ± 1.9; P < .005. Finally, the pre- and postoperative means of differences of lowest oxygen saturation values were not statistically significant among the three groups (P > .05). CONCLUSION: Barbed reposition pharyngoplasty (BRP) can be considered an effective procedure on the basis of the postoperative outcomes. ESP still proves to be a good technique especially when performed by experienced surgeons. Both techniques proved to be superior to UPPP.

Secondary malignant tumors of the parotid gland: not a secondary problem!

PURPOSE: To present the clinical features of patients with parotid gland metastasis, and compare the results with previously published series. Most of the relevant literature arises from case reports, while there are only few series reported, as secondary neoplastic lesions of the parotid gland are uncommon. METHODS: The medical records of patients with parotid gland metastasis, treated at the ENT Department of the University Hospital of Ferrara, between January 1st 1965 and December 31th 2014, were retrospectively reviewed. Fine needle aspiration cytology (FNAC) and biopsy results were compared. Localization of the primary tumor was searched in all cases. Lymphomatous lesions have been excluded from the study. RESULTS: A total of 66 patients with parotid gland metastasis were evaluated. There were 53 males and 13 females with mean age 68.2 ± 13.5 years. Histopathologic analysis of the lesions revealed that 47 (71.2%) were parotid gland metastasis from cutaneous head and neck tumors, 8 (12.1%) from the upper aero-digestive tract, 7 (12.1%) from locations out of facial-cervical region, 1 from a conjunctival melanoma, while in 3 (4.5%) cases the primary tumor origin remained unknown. FNAC results were compared with the final histopathologic diagnosis, showing an overall concordance of 71.9%. CONCLUSION: The present study is one of the largest series of parotid gland metastasis available so far. During the diagnostic work-up of a parotid tumor, the possibility of a metastasis should also be considered. FNAC can be a useful tool for the preoperative assessment of parotid lesions.

Head and neck cancer patients: impact of diabetes mellitus on surgical outcomes.

PURPOSE: Cancer patients with significant comorbidities undergoing major surgical intervention are at high risk for peri/postoperative complications and a prolonged hospital stay. Diabetes mellitus is a prevalent chronic metabolic disease, reported to affect surgery outcomes of malignancies. The purpose of this article was to evaluate the impact of diabetes mellitus on the development of local and systemic complications as well as the length of the hospital stay, after major surgery for Head and Neck (H&N) cancer. METHODS: A total of 168 patients suffering from H&N cancer, surgically treated between 2004 and 2013 at our ENT Department, were included. Clinical records were examined, particularly focusing on the onset of local and systemic complications and on the length of the hospital stay. The subjects considered as diabetics were the ones with a history of physician-diagnosed diabetes or those who were taking oral hypoglycemic drugs or insulin. For those without a diagnosis of diabetes and not taking any antidiabetic medications, the value of fasting blood glucose was used to assess the presence of diabetes, according to the American Diabetes Association guidelines (glycaemia >126 mg/dl). The occurrence of local and systemic postoperative complications, as well as the length of the hospital stay, were statistically compared between the diabetic and non-diabetic group of patients. RESULTS: 31 of 168 (18.5%) patients, surgically treated for H&N cancer, had also been diagnosed with diabetes mellitus. Episodes of postoperative complications in non-diabetic patients were 50.4%, whereas in diabetics 45.2%. The mean length of hospital stay for non-diabetics was 28.1±14.8 days and for diabetics 32.2±24. In univariate and multivariate analysis, no statistically significant differences were found when comparing the diabetic to the non-diabetic group, in terms of occurrence of postoperative complications in respect to cancer stage and length of hospitalization. In univariate and multivariate analyses none of the variables studied was a risk factor for postoperative complications. CONCLUSIONS: This study provides evidence that a good metabolic control of diabetes mellitus does not have impact on the occurrence of peri/postoperative complications and therefore on the length of hospital stay of H&N cancer patients.

Supracricoid partial laryngectomy: oncological and functional results.

PURPOSE: The purpose of this study was to evaluate the oncological and functional results of patients affected by laryngeal squamous cell carcinoma (SCC) and surgically treated by supracricoid partial laryngectomy (SCPL) at the ENT Department of the University Hospital of Ferrara. METHODS: In this retrospective study a total of 155 patients (149 males/l96.1% and 6 females/3.9%), have been included. All patients were treated between January 1st 1998 and December 31st 2010, by SCPL, including 126 cricohyoidopexies (CHP) and 29 cricohyoidoepiglottopexies (CHEP). RESULTS: The overall survival (OS) at 3 and 5 years was 88.77 and 83.24%, respectively and the disease-free survival (DFS) at 3 and 5 years was 84.4 and 81.55%, respectively.The recurrence rate was 17.5%, with local recurrences in 12.1% of the cases, regional in 4.7% and distant metastasis in 0.7% of the cases. Synchronous second primary tumors were 0.7% and metachronous second primary cancers (MSPCs) 5.4%. Removal of nasogastric feeding tube (NGT) or percutaneous endoscopic gastrostomy (PEG) was performed in 98.7% of the patients and lasted 22 days on average after SCPL (range 9-60), while decannulation was performed in all of patients at the 27th day on average after surgery. CONCLUSIONS: Oncological outcomes of this series are consistent with those of the literature, showing that SCPL is an effective and safe procedure in terms of survival rate and disease control. Functional outcomes confirmed that SCPL allows a good organ preservation and recovery of laryngeal functions.
