In the last decade, the incidence and mortality associated with laryngeal malignancies has experienced an unfavorable evolution in Romania, in terms of this pathology the country that has become the leader, among the European Union (EU)-27 countries. The aim of the present retrospective study was to analyze the epidemiological data regarding laryngeal cancer and histopathological (HP) particularities in patients diagnosed in Western Romania. Within three years and 10 months (during October 2016-July 2020) in Ear, Nose and Throat (ENT) Clinic of Timişoara Municipal Emergency Clinical Hospital, 194 patients with laryngeal neoplasms (LN) were diagnosed. Most of the patients were male (93.8%), from Timiş County, mainly and the neighboring Counties of Caraş-Severin, Hunedoara, Mehedinţi and Arad. Patient's average age (both sexes) was 62.6 years, with a range from 38 to 84 years and the highest percentages in the 60+ age group (48%). Regarding smoker status, the main cause of the development of the LN, 93.9% of patients were active ones. Regarding localization [International Classification of Diseases 11th Revision (ICD-11)], about 69% were malignant neoplasm of glottis (C32.0), followed by supraglottis (C32.1), larynx-unspecified (C32.9), and subglottis (C32.2). From the HP point of view, several types of tumors were identified, most of which were non-keratinized and keratinized squamous cell carcinomas (about 90%). In addition, there were identified types of verrucous carcinoma, acantholytic carcinoma, squamous papilloma, a possible pleomorphic sarcoma, and pyogenic granuloma. The data presented in this study highlight the growing incidence of LN, which mainly affect men, at an increasingly young age. It is imperative to involve specialists from nutrition, general medicine, ENT, dentistry to start awareness programs and to develop prevention protocols.

BACKGROUND
Radiotherapy is a standard treatment option for early glottic carcinoma (stage I and II) with a fraction size of 2-2.2 Gy over 5-7 weeks. This study evaluates the outcome and prognostic factors of a 3-week hypofractionated treatment in early glottic malignancy.
MATERIALS AND METHODS
The case records of 329 eligible patients with stage I and II glottic carcinoma recorded at the institution from 2003 to 2008 were retrospectively analysed. All patients were treated in a Cobalt-60 machine to a dose of 52.5 Gy in 15 fractions (3.5 Gy/fraction) over 3 weeks.
RESULTS
Eighty-three percent had stage I disease. The local control rate at 5 years was 91.9%. On univariate analysis, stage I and II patients without subglottic extension had better local control. Disease extension to the subglottis fared poorly on multivariate analysis. After salvage treatment, the 5-year disease-free survival rate was 96.1% and the functional larynx preservation rate was 94.9% for stage I and 83.9% for stage II. The rate of severe complications was 2.1%.
CONCLUSION
Comparable results with low morbidity are achievable with a 3-week hypofractionation in early glottic cancers and it offers better patient convenience.
HIGHLIGHTS
In early glottic cancer, hypofractionated radiation provides excellent local control.Subglottic extension is a poor prognostic factor.5-year disease-free survival rate of 96.1%.5-year functional larynx preservation rate of 94.9%.Severe complication rate of 2.1%.

INTRODUCTION
Benign lymphoid hyperplasia uncommonly involves the larynx. Involvement of glottis and subglottis is even rare, considering sparse lymphatic supply compared to supraglottis.
CASE REPORT
A young female presented to emergency with worsening breathing difficulty. After securing the airway, she had found to have circumferential glottis and subglottic mucosa covered firm swelling. Histopathological evaluation of the swelling showed it to be benign lymphoid hyperplasia. Coblation assisted excision of the lesion was done, and the patient became asymptomatic without any recurrence.
CONCLUSION
Idiopathic lymphoid hyperplasia is a very rare entity to present as glottis and subglottic lesions. Probably, it's the first case to be reported in the literature as laryngeal involvement sparing the supraglottis.

Foreign body aspiration in children, specifically sharp and metallic type, imposes a serious morbidity and mortality risk if intervention is delayed. The bronchoscopic removal of sharp metallic foreign bodies is technically challenging for the operating surgeon. We present a case of an 8-year-old girl who presented with an alleged history of aspiration of metallic, sharp and open safety pin 8 hours prior to presentation following which she developed throat pain and painful swallowing. X-ray of soft tissue neck showed a radio-opaque foreign body being lodged in the supraglottic area. She underwent emergency direct laryngoscopy-guided foreign body removal under general anesthesia. There was an open metallic sharp safety pin hinged over the inter-arytenoid region with its one end reaching sub-glottis and other end toward the hypopharynx. No post-operative complications occurred and patient was discharged on the third post-operative day.

Comparative Study
OBJECTIVES/HYPOTHESIS
Laryngotracheal stenosis (LTS) is a functionally devastating condition with high respiratory morbidity and mortality. This preliminary study investigates airflow dynamics and stenotic drug delivery in patients with one- and two-level LTS.
STUDY DESIGN
A Computational Modeling Restropective Cohort Study.
METHODS
Computed tomography scans from seven LTS patients, five with one-level (three subglottic, two tracheal), and two with two-level (glottis + trachea, glottis + subglottis) were used to reconstruct patient-specific three-dimensional upper airway models. Airflow and orally inhaled drug particle transport were simulated using computational fluid dynamics modeling. Drug particle transport was simulated for 1-20 μm particles released into the mouth at velocities of 0 m/s, 1 m/s, 3 m/s, and 10 m/s for metered dose inhaler (MDI) and 0 m/s for dry powder inhaler (DPI) simulations. Airflow resistance and stenotic drug deposition in the patients' airway models were compared.
RESULTS
Overall, there was increased airflow resistance at stenotic sites in subjects with two-level versus one-level stenosis (0.136 Pa s/ml vs. 0.069 Pa s/ml averages). Subjects with two-level stenosis had greater particle deposition at sites of stenosis compared to subjects with one-level stenosis (average deposition 2.31% vs. 0.96%). One-level stenosis subjects, as well as one two-level stenosis subject, had the greatest deposition using MDI with a spacer (0 m/s): 2.59% and 4.34%, respectively. The second two-level stenosis subject had the greatest deposition using DPI (3.45%). Maximum deposition across all stenotic subtypes except one-level tracheal stenosis was achieved with particle sizes of 6-10 μm.
CONCLUSIONS
Our results suggest that patients with two-level LTS may experience a more constricted laryngotracheal airflow profile compared to patients with one-level LTS, which may enhance overall stenotic drug deposition.

Inflammatory myofibroblastic tumor (IMT) is a very rare mesenchymal tumor that can behave as a locally benign or aggressive lesion. Here, we present an extremely rare case of IMT involving the subglottic of a middle-aged male. Steroid therapy treatment alleviated dyspnea, but the recurrence of dyspnea was reported two months later. Both sides of the subglottic tumor were excised following treatment, and the surgical specimens were subjected to histopathological evaluation and diagnosis for IMT. At 4 years after excision, follow-up laryngoscopy revealed symmetric vocal cords without evidence of any subglottic mass. Subglottic mass is often asymptomatic until it presents with hoarseness or dyspnea, and subglottic IMT is rare. Based on the successful treatment of our case, complete surgical excision is highly recommended for this rare tumor. However, further research is needed to discover a more effective and cost-effective treatment approach.

The larynx is at the aerodigestive crossroads; any pathology that involves it will have an impact on breathing, swallowing and/or the voice. It`s divided into three regions: supraglottis (includes epiglottis, ventricular bands and laryngeal ventricles), glottis (space limited by the vocal cords) and subglottis (narrowest area of pediatric airway and the only point of larynx completely surrounded by cartilage: the cricoid ring). Laryngeal obstruction can present as a potentially fatal acute condition or as a chronic process. The main symptom is inspiratory or biphasic stridor. The etiology varies widely according to age and it may be of congenital, inflammatory, infectious, traumatic, neoplastic or iatrogenic origin. We describe the pathologies that cause laryngeal obstruction, either those that occur very often or those which are important for their severity, their guiding symptoms to the presumptive diagnosis, additional studies and treatment.

A 66-year-old man presented with a 2.8 cm lesion of the left vocal cord. On contrast-enhanced computed tomography scans, the tumor extended to the supraglottis, subglottis, paraglottic space and anterior commissure, causing partial obstruction of the laryngeal lumen. At another hospital, a fragmented incisional biopsy was diagnosed as a granular cell tumor, as to the S-100 immunohistochemical positivity. After excision, the tumor revealed to be an adult-type laryngeal rhabdomyoma. The typical cytoplasmic rod-like inclusions and cross striations were more evident in the second specimen. We confirmed the unusual S-100 immunohistochemical positivity (variable intensity, >90% of tumor cells). Muscle markers were not performed on the previous biopsy, resulting positive in our specimen (Desmin: strong, diffuse expression; Smooth Muscle Actin: strong staining in 10% of tumor cells). Melan-A, CD68, GFAP, pan-cytokeratins, CEA, calretinin and neurofilaments resulted negative. To our brief, systematic literature review, S-100 positivity (usually variable, often weak or patchy/focal) was globally found in 19/34 (56%) adult-type rhabdomyomas of the head and neck region. Especially on fragmented biopsy material, the differential diagnoses of laryngeal rhabdomyomas may include granular cell tumors, oncocytic tumors of the salivary glands or of different origin, and paragangliomas.

Review
OBJECTIVES
(1) To highlight the important causes of chronic and recurrent cough in children. (2) To discuss multidisciplinary approach to management of chronic/recurrent pediatric cough.
METHODS
Review of scholarly articles, guidelines, expert panels via PubMed and Google Scholar.
CONCLUSION
Chronic cough (CC) in children is mainly attributed to persistent bacterial bronchitis, asthma, nonspecific cough, and gastroesophageal reflux disease (GERD) symptoms. A multi-disciplinary approach is cost-effective and aids with earlier diagnosis and appropriate treatment. Congenital or acquired narrowing of the subglottis is the leading ENT cause for recurrent croup (RC) in children. Laryngeal cleft-type 1 is commonly seen in children with recurrent aspiration and CC. Children are usually referred to pulmonologists for wet cough not responding to treatment. Eosinophilic esophagitis (EoE) and GERD should be considered in the differential diagnosis of CC in children with both respiratory symptoms and failure to thrive.Level of Evidence: 2a.
