Thyroid lobectomy has gained increasing popularity over the past decade as a treatment for differentiated thyroid cancer (DTC), largely due to a rise in the diagnosis of low-risk cancers and evidence showing no benefit from radioiodine in low-risk disease. Multiple studies have confirmed lobectomy as an effective and safe option. Its advantages over total thyroidectomy include lower complication rates and a reduced need for lifelong levothyroxine (LT4) therapy.

Background: Depth of invasion (DOI) has a significant clinical impact on the staging system of oral squamous cell carcinoma (OSCC). We aimed to compare the prognostic impact of treating DOI as a continuous variable rather than a categorical one.

Methods: A retrospective review of 277 OSCC patients surgically treated in a tertiary care center from 2000 to 2020, with a minimum 2-year follow-up.

Article Synopsis
  • The study investigates factors impacting the treatment and outcomes of iatrogenic cervical oesophageal and hypopharyngeal perforations (iCEHPs) by analyzing data from 24 patients treated from 2004 to 2021.
  • It was found that surgical neck exploration was the most common treatment, especially for uncontained perforations, and patients managed surgically typically had higher C-reactive protein (CRP) levels.
  • Key findings highlighted that delayed diagnosis increases mortality risk, and a history of neck irradiation significantly worsens patient prognosis.

Purpose: To estimate long-term prognosis of chemosensory dysfunctions among patients recovering from COVID-19 disease.

Methods: Between April 2020 and July 2022, we conducted a prospective, observational study enrolling 48 patients who experienced smell and/or taste dysfunction during the acute-phase of COVID-19. Patients were evaluated for chemosensory function up to 24 months after disease onset.

Objectives: Tumor depth of invasion is a known prognostic factor in several head and neck cancers, but data on early laryngeal squamous cell carcinoma (SCC) are sparse. In this study, we aim to determine whether radiological tumor thickness serves as a prognostic factor in early SCC of the glottis treated with radiation.

Methods: One hundred thirty-two adult patients (age >18 years) underwent pretreatment computed tomography (CT) and were treated with radiation for pathologically proven early stage (T1 or T2) glottic SCC.

In recent years, the field of head and neck oncology has witnessed a remarkable transformation with unprecedented advances that have revolutionized the management of complex tumors in this region. As an intricate subspecialty within oncology, head and neck surgical procedures demand detailed knowledge of the complex anatomy meticulous precision in surgical technique, and expertise to preserve vital functions while ensuring optimal oncological outcomes. With the relentless pursuit of improved patient outcomes, the integration of innovative technologies has significantly enhanced the surgical armamentarium.

Objectives: Postoperative antibiotic therapy is a common practice following septoplasty with intra-septal splints placement (ISS), even though there is a lack of evidence to support it. We sought to investigate the role of antibiotic therapy in septal surgeries with the placement of ISS.

Design: A retrospective comparative study was conducted using the electronic charts of adult patients who underwent septoplasty with the placement of ISS with or without turbinate reduction.

Purpose: This study examines the impact of concomitant mucosal inflammation on clinical manifestations and long-term outcomes of Inverted Papilloma (IP).

Methods: This retrospective cohort study was conducted in five tertiary medical centers. The included patients underwent an attachment-oriented surgical resection for IP with a minimum follow-up of 3 years.

Biofilm-state bacterial infections associated with inserted medical devices constitute a massive health and financial problem worldwide. Although bacteria exhibit significantly lower susceptibility to antibiotics in the biofilm state, the most common treatment approach still relies on antibiotics, exacerbating the phenomenon of antibiotic-resistant bacteria. In this study, we aimed to assess whether ZnCl coating of intranasal silicone splints (ISSs) can reduce the biofilm infections associated with the insertion of these devices and prevent the overuse of antibiotics while minimizing waste, pollution and costs.

Article Synopsis
  • Immunosuppression, particularly in solid organ transplant recipients and chronic lymphocytic leukemia patients, significantly increases the risk of developing aggressive cutaneous squamous cell carcinoma (cSCC) compared to immunocompetent individuals.
  • This study analyzed 465 cSCC patients, comparing clinical features, treatments, and survival rates between immunosuppressed patients and controls with cSCC.
  • Results showed immunosuppressed patients had higher rates of tumor recurrence, multiple tumors, and poorer overall survival rates, especially among those receiving immunomodulating treatments, with solid organ transplant recipients exhibiting the most severe outcomes.

Background: Acute invasive fungal rhinosinusitis has been associated with high mortality rates.

Objective: We aimed to explore the contribution of novel detection and treatment methods on the outcome of immunosuppressed children with acute invasive fungal rhinosinusitis.

Methods: The records of all children with a hematologic or oncologic disease who developed acute invasive fungal rhinosinusitis between 2005-2020 were reviewed.

While the popularity of lobectomy for differentiated thyroid cancer (DTC) has increased since the 2015 ATA (American Thyroid Association) guidelines, recent studies reported that adverse histological features (minimal extrathyroidal extension [mETE], multifocality, vascular invasion, and lymph node [LN] metastases) may be found in 30-60% of lobectomy specimens, questioning the validity of this approach. To assess the prevalence adverse histological features in occult DTC detected in autopsy studies. Meta-analysis of autopsy studies of the thyroid in subjects without known history of thyroid cancer.

Background: Obstructive sleep apnea (OSA) is associated with a significantly increased risk of motor vehicle accidents in addition to such cognitive impairments as attention and memory deficits. The aim of the study was to examine the effect of upper airway surgery for OSA on driving and cognitive function.

Methods: Adult patients who underwent surgery for OSA at a tertiary medical center in 2016-2019 were prospectively recruited.

Background: Cutaneous squamous cell carcinoma of the head and neck (CSCC-HN) appears to behave more aggressively in immunosuppressed patients. We aimed to investigate this hypothesis by comparing solid organ transplant recipients (SOTR) with CSCC-HN to immunocompetent patients.

Methods: A retrospective comparative study was conducted for SOTR and immunocompetent patients who were treated for CSCC-HN.
