Directed energy deposition (DED) is a crucial branch of additive manufacturing (AM), performing repairs, cladding, and processing of multi-material components. 316L austenitic stainless steel is widely used in applications such as the food, aerospace, automotive, marine, energy, biomedical, and nuclear reactor industries. Nevertheless, there is need for process parameter optimization and a comprehensive understanding of the individual and complex synergistic effects of process parameters on the geometry, microstructure, and properties of the deposited material or component.

Background: Granulomatosis with polyangiitis (GPA) otologic manifestations include conductive and sensorineural hearing loss (HL). Vasculitis is assumed to be the primary cause of otologic manifestations. Deaf patients and patients with HL who do not benefit from hearing aids can benefit from cochlear implants (CI).

Study Design: A retrospective case series in a single academic center.
Rehabilitating hearing loss is highly important due to its positive impact on the ability to understand speech, and the related consequences on family, social and work communication abilities. Children with hearing loss have learning difficulties that adversely affect speech and language acquirement. Most patients with hearing loss can use conventional hearing aids that are partially or completely placed in the external ear canal.

This study aims to evaluate long-term eDCR efficacy and safety in the old and oldest-old population.
Methods: A retrospective case-control study of patients aged 80 ≤ (oldest-old) and 65-79 (old) compared with younger controls who underwent eDCR, between 2002 and 2017.
Background: Antrochoanal polyp (ACP) is a rare and unique unilateral nasal polyp. In contrast to diffuse primary chronic rhinosinusitis (d-CRS) the inflammatory profile of ACP in the Caucasian population have not been determined.
Objective: The purpose of the study is to describe and differentiate the inflammatory features of ACP compared with d-CRS and its phenotypic subgroups and hypertrophic turbinates (HT) in the Caucasian population, and compare the mast and plasma cell marker expression of each pathology.
Purpose: Thyroglossal duct cyst (TGDC) may appear in all age groups. The impact of age on surgical outcome has been reported with conflicting results. The aim of the study was to evaluate different risk factors for surgical success according to stratified age groups.

This study investigates whether the clinical course of SG-SCC in IVDA differs from SG-SCC in non-IVDA.
Study Design: A retrospective case-control study conducted in a in two tertiary referral centers.
Purpose: Managing persistent epistaxis poses a great challenge for the otolaryngologist. Despite continuous development in treatment methods, no universal guideline has been commonly adopted. Among the popular methods is endoscopic sphenopalatine artery ligation (ESPAL).

Our experience and recent publications suggest fat implantation may deliver a long-lasting improvement. This study aims to present the long-term outcomes for vocal fold fat augmentation using strict harvesting, preparing, and implantation protocols.
View Article and Find Full Text PDFBackground: The impact of body mass index (BMI) on pharyngeal fat pads has been well studied, yet no study has assessed its associations on laryngeal morphology.
Objectives: To study the associations of BMI differences on laryngeal morphology in adult males using computed tomography angiography (CTA) scans.
Methods: All adult male patients who underwent head and neck CTAs between 2011 and 2018 were initially included and categorized according to their BMI: (1) BMI < 20; (2) 20 ≤ BMI < 25; (3) 25 ≤ BMI < 30; (4) 30 ≤ BMI < 35; and (5) BMI ≥ 35.
Allergies and smoking are common reasons for nasal mucosa inflammations, which in turn, cause nasal obstructions. Nevertheless, the impact of coexisting allergies and smoking on nasal mucosa inflammation has not been studied. To study the impact of smoking with relation to allergies on nasal mucosa histology and to characterize an immunologic profile using immunohistochemical (IHC) staining.

This study aimed to evaluate three aspects of revision END-DCR: 5-year success rates, patient satisfaction, and the primary surgical approach's possible impact on revision.
Methods: This retrospective study included all revision END-DCRs conducted at Kaplan Medical Center between the years 2002 and 2015.

Purpose: Spontaneous neck hematoma is a rare yet potentially fatal complication of primary hyperparathyroidism (PHPT). Here we aim to describe novel presentations of neck hematomas secondary to PHPT, discussing tools and signs that facilitate diagnosis.
Methods: Case series data were extracted by retrospective chart reviews of our institution's electronic medical records, including all neck hematoma cases from parathyroid origin between 2005 and 2020.
Surgeon performed ultrasound (SUS) has become a valuable tool for the head and neck/endocrine surgeon. It allows for a complementary examination of the neck, following history and physical examination. With its reduced costs and being radiation free, US has become the modality of choice for imaging thyroid, parathyroid and lymph nodes of the neck.

Background And Objectives: CO laser cordectomy has been the workhorse of laser surgery for early glottic squamous cell carcinoma (GSCC) since the early 1970s. During the last decades, potassium titanyl phosphate (KTP) laser surgery for early GSCC gained popularity, introducing the tumor ablation technique. Yet, there are no previous randomized controlled trials (RCT) that compare the oncologic and functional outcomes of KTP Laser ablation versus CO laser cordectomy for early GSCC.
