Paragangliomas of the Head and Neck: A Review of the Latest Diagnostic and Treatment Methods.

Background and objectives: Paragangliomas of the head and neck are rare, slow-growing neuroendocrine tumors, benign in their vast majority, but with a possibility of developing distant metastases. They show great inheritable character, and their behavior has proven to be unpredictable; therefore, they are considered malignant. Material and methods: This article aims to offer a more comprehensive presentation of the pathogenesis, epidemiology, diagnostic methods, imaging development, and treatment guidelines. We tried to bring together all the necessary data that, in our opinion, a head and neck practitioner should know when managing this type of tumor. Our main focus is on the most recent studies, with the purpose of a homogenous presentation of all current guidelines and approaches to this pathology. Results: Paragangliomas of the head and neck are still a disputed topic. One of the main reasons for that is their low incidence of 0.3 to 1 per 100,000 every year. The most frequent locations are the carotid body, the temporal bone, the jugular and mastoid foramen, and the vagal nerve. Their clinical presentation usually involves a painless lateral mass associated with symptoms such as hoarseness, hearing loss, tinnitus, and cranial nerve deficits. Up to 40% of them are inherited, mostly linked with mutations of succinate dehydrogenase complex. Imaging evaluation consists of CT and MRI, and new functional explorations such as 18F-FDA and 18F-FDG PET/CT, 18F-DOPA PET, 123I-MIBG, and 68Ga-DOTATE PET/CT. Measuring the catecholamine levels in the plasma and urine is mandatory, even though paragangliomas of the head and neck rarely display secretory behavior. Treatment mainly consists of surgery, with different approaches and techniques, but conservative management methods such as wait and scan, radiotherapy, proton therapy, and chemotherapy have proven their efficiency. The therapeutical decision lacks consensus, and current studies tend to recommend an individualized approach. Guidelines regarding long-term follow-up are still a matter of debate.

Hospitalizations for Acute Otitis and Sinusitis in Patients Living with HIV: A Retrospective Analysis of a Tertiary Center in Romania.

Background/Objectives: Acute or chronic ear, nose and throat (ENT) conditions in people living with HIV can lead to hospitalization and affect their quality of life. The aim of our study was to determine the frequency and characteristics of hospitalizations for acute sinusitis (AS) and acute otitis (AO) in people living with HIV. Methods: We performed a retrospective analysis over the course of six years (from January 2018 to December 2023), assessing all hospitalizations for AS and/or AO occurring in patients living with HIV, at the largest infectious diseases hospital in Romania. Results: We identified a total of 179 cases, among which 149 cases (83.2%) were attributed to AS and 41 cases (22.9%) were due to AO. Among cases of AS, maxillary sinuses were most frequently involved (n = 140/149, 94.0%), and among cases of AO, acute congestive otitis media (n = 14, 34.1%) and acute purulent otitis media (n = 13, 31.7%) were the most common forms. The underlying HIV infection was classified as stage C3 in 57.5% of cases. In 19.6% of cases, it was possible to identify either the trigger or the etiological agent, and the most frequent bacterial pathogens were Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae and Pseudomonas aeruginosa. Conclusions: In conclusion, this study highlights that hospitalizations due to acute sinus and ear involvement are not isolated events in people living with HIV. A prospective follow-up is needed to gain a deeper and more dynamic understanding of how ENT health is affected in people with HIV infection. Furthermore, promoting prevention through vaccination may reduce to a certain extent the burden of ENT infections in this population.

Laryngeal Paraganglioma-A Case Report.

Background and Objectives: Paragangliomas of the head and neck are rare neuroendocrine tumors originating from the paraganglia, which might be sympathetic or parasympathetic. Laryngeal paragangliomas are the rarest subtype of these tumors, with only 1.41% of all paragangliomas, arising from the supraglottic or subglottic paraganglia of the larynx. The vast majority of them are benign, but there are some cases in which they turn out to be malignant, and the only way to know with certainty the difference between them is when we identify distant metastases. The aim of this article is to share our experience with a rare case of laryngeal paraganglioma and review the clinical characteristics, methods of diagnostic, necessary investigation prior to the operation, and surgical management of this type of tumor. Materials and Methods: We present the case of a 68-year-old female patient, a non-smoker, who accused dysphagia, dysphonia, foreign body sensation, chronic cough, and hoarseness for six months. We performed a tracheostomy prior to biopsy to secure the airways in case of bleeding and then took a few biopsy samples. The histopathological exam revealed the presence of a laryngeal paraganglioma. An enhanced CT scan was performed in order to describe the localization, size, and invasion of the tumor. We also measured the vanillylmandelic acid from the urine to determine if the tumor produced catecholamines alongside a full cardiology and endocrinology examinations. In order to prevent massive bleeding during the operation, chemoembolization was attempted before surgery, but it was unsuccessful due to an anatomical variation of the left superior thyroid artery. She underwent surgery, first through transoral endoscopic microsurgery; however, we decided to undertake an external approach because of poor bleeding control, even though we had ligated both the superior thyroid artery and the external carotid artery, with a thyrotomy and laryngofissure achieving the complete resection of the tumor. Results: The patient was discharged 10 postoperative days later, with the recommendation of introducing food step-by-step from liquids to solids. She was decannulated after 30 days, with no complications regarding breathing, phonation, or deglutition. Twelve months after the surgery, we did not identify any local relapses of distant metastases. Conclusions: Laryngeal paragangliomas are rare neuroendocrine tumors that arise from the laryngeal paraganglia. Surgery is the best treatment option available, and it can be done by either an external approach or by transoral endoscopy. Enhanced CT or MRI, as well as full cardiological and endocrinological evaluation are mandatory prior to the operation. Measuring the catecholamines levels show the if the tumor is secretory. Controlling the bleeding poses the biggest challenge in performing the resection of the tumor, especially when a transoral endoscopic approach is chosen. Further standardized follow-up guidelines are required in the future.

Management of Capillary Hemangioma of the Sphenoid Sinus.

Background and objectives: Capillary hemangiomas are rare, benign vascular tumors that mainly affect the skin and soft tissue, with scarce appearance within the nasal cavities and paranasal sinuses. Materials and methods: We present a case report of capillary hemangioma of the sphenoid sinus and a review of the literature in the last ten years. Results: Clinical and endoscopic examination of the nose, radiologic assessment and particular histologic features contribute to the correct diagnosis of capillary hemangioma of the nose and paranasal sinuses. Conclusions: Transnasal endoscopic resection of capillary hemangioma located in the nose and paranasal sinuses is a valuable treatment method with good outcomes.

Use and Abuse of Electrocautery in Adenoidectomy Hemostasis.

Background and objectives: Bipolar electrocautery is commonly used to control bleeding after cold-instrument pediatric adenoidectomy, but the surgeon should be aware of the possible side effects. OBJECTIVE: The aim of our study is to investigate the effects of bipolar electrocautery when used for bleeding control at the end of an adenoidectomy procedure. Materials and Methods: We evaluated the effect of electrocautery on postoperative pain, velopharyngeal insufficiency symptoms, postoperative nasal obstruction, and rhinorrhea in a group of 90 children undergoing adenoidectomy in our ENT department over a period of 3 months. Results: After statistically analyzing the data, we found that the duration of postoperative pain, the duration of rhinorrhea and nasal obstruction, and the duration of painkiller administration, as well as the velopharyngeal insufficiency symptoms, were significantly longer in patients in whom electrocautery was used for hemostasis. A significantly higher incidence of posterior neck pain and halitosis (oral malodor) was noted in the patients in whom electrocautery was used for adenoidectomy hemostasis. Conclusions: Bipolar electrocautery use should be limited during pediatric adenoidectomy hemostasis because of the possible side effects: longer postoperative pain, prolonged nasal obstruction, rhinorrhea and velopharyngeal insufficiency, and halitosis. We noted some side effects that were specific to electrocautery use during adenoidectomy: posterior neck pain and oral malodor. Acknowledging the risk for these symptoms can help to alleviate the anxiety of both the parents and the patients regarding the expected postoperative outcomes.

The Role of Inverted Papilloma Surgical Removal for Sleep Apnea Treatment Success-A Case Report.

In recent years, increased attention has been directed to sleep apnea syndrome due to its high prevalence and preventable severe health consequences. Besides enhancing the risk of cardiovascular, cerebrovascular, and metabolic disorders, it determines increased daytime somnolence, cognitive impairment, and delayed reaction time. These symptoms, determined by sleep fragmentation and chronic hypoxemia, can result in a decrease in professional performance and, moreover, could have tragic implications, especially in patients with high-risk professions. We present the case of a 58-year-old male-truck driver, known to suffer from uncontrolled OSA and chronic obstructive pulmonary disease, who presented to our ENT department for incapacitating daytime somnolence and severe nasal obstruction. These symptoms were caused by a voluminous sinonasal inverted papilloma, occupying the entire left cavity with extension in the nasopharynx. Following nose permeabilization, the patients' APAP compliance grew substantially, with a dramatic decrease in daytime sleepiness and improvement in polysomnographic parameters. Due to the overlap syndrome of OSA and COPD, an oxygen supplementation was added to PAP therapy by a pulmonologist, improving pulse-oximetry parameters and resulting in the best outcome for the patient. Through this case report, we aim to emphasize the importance of multimodal, personalized treatment of sleep apnea with a focus on nasal surgical permeabilization. At the same time, we sustain a multidisciplinary approach, especially in patients with sleep apnea and associated pathologies, to obtain therapeutic success. We propose increased attention to the early recognition and proper treatment of sleep apnea in patients with high-risk professions as it prevents catastrophes.

Multicenter Epidemiological Study of Nosebleeds Requiring Hospitalization.

Epistaxis is a common presenting symptom either emergency condition or ambulatory in Otorhinolaryngology, affecting people of all ages. A multicentric retrospective descriptive study of 380 patients who were hospitalized with epistaxis over a 3.8 year period was carried out. Data collected was analyzed using IBM SPSS Statistics 25 and illustrated using Microsoft Office/Word 2016. The current study showed that male adults after 60 years old are most affected by nasal bleeding. More than half of hospitalized patients have severe epistaxis at the time of hospitalization. However, further studies are necessary to be done in order to fully elucidate the epidemiology of nosebleeds requiring hospitalization.

Etiological Profile of Epistaxis: Pre-Pandemic Versus Pandemic.

Nosebleed or epistaxis is one of the most common forms of presenting an emergency in the ENT field. Since March 11, 2020, the World Health Organisation has proclaimed COVID-19 a global pandemic, and the world has been closed down. The main objective of the study is to analyse and compare the dynamics of epistaxis aetiology among the cases that required hospitalisation in the pre-pandemic period and the period of the COVID 19 pandemic. The study is multicenter retrospective from October 2018 to May 2022, including 380 cases of hospitalised epistaxis, with the mention that March 2020 is considered the beginning of the pandemic period. 60.8% of the patients enrolled in the study in the pre-pandemic period (60.8%) and 39.2% in the pandemic period. Differences between groups were not statistically significant between study entries (pre-pandemic vs. pandemic) and age (p=0.331), gender (p=0.916) or existence of local causes for epistaxis (p=0.895). Patients with general causes for epistaxis were more frequently enrolled in the pandemic period, while patients without general causes for epistaxis were more frequently enrolled in the pre-pandemic period. Patients with a hospitalisation period of more than 5 days were more frequently enrolled in the pre-pandemic period while patients with a hospitalisation period of 3 to 5 days were more frequently enrolled in the pandemic period. Also, patients with idiopathic epistaxis were more frequently enrolled in the pre-pandemic period. Based on the results presented in our study, the period of the Covid 19 pandemic directly influenced both the number of patients and the period of hospitalisation.

Current approach of juvenile nasopharyngeal angiofibroma: a case series.

Juvenile nasopharyngeal angiofibroma (JNA) is a rare benign tumor that affects predominantly males and is known by its highly vascular character. We have performed a 3-year retrospective study of patients with JNA surgically treated within the third ENT Department of Prof. Dr. Dorin Hociota Institute of Phonoaudiology and Functional ENT Surgery, Bucharest, Romania. In all the cases, the patients were investigated both clinically and through medical imaging before surgery and all tumors were embolized. Our study comprised of eight cases, of which seven were solved by endoscopic endonasal approach and one case was treated through a combined endonasal-external approach. JNA should always be managed through a multidisciplinary team (MDT) approach in centers with adequate experience, to gain favorable results.
