Clinicopathological Findings of Surgically Treated Nasal Cavity Schwannomas: A Case Series.

Nasal cavity schwannomas are exceedingly rare, benign neoplasms that pose challenges in clinical differentiation from other nasal tumors. This study presents 5 cases of nasal cavity schwannoma treated surgically over a 10 year period, along with a review of the literature. The most prevalent symptoms included unilateral nasal obstruction and intermittent nosebleeds.

Effects of classical olfactory training in patients with COVID-19-related persistent loss of smell.

Purpose: The management of post-COVID-19 persistent olfactory dysfunction (OD) is uncertain. Currently, olfactory training is the only evidence-based therapy for post-viral OD. In this study, we evaluated the effectiveness of classical olfactory training (COT) in the treatment of post-COVID-19 persistent OD.

Anterior maxillary wall and lacrimal duct relationship in pediatric patients - CT analysis for the feasibility of the prelacrimal recess approach.

Objective: The purpose of the current study is to determine the age-related feasibility rate of the intranasal endoscopic prelacrimal recess approach (PLRA) in pediatric patients.

Methods: Computed tomography (CT) images of 379 patients under 18 years old were analyzed retrospectively. The anteroposterior dimensions of the medial bony wall of the prelacrimal recess (PLR) were measured on 758 sides.

Age-dependent differences of the depth of olfactory fossa in children.

Objective: With this radio-anatomical study, we aimed to describe the distribution of the depth of the olfactory fossa based on the Keros classification in the pediatric population in our region and to reduce complication rates by providing normative data.

Methods: This was a retrospective study conducted with computed tomography imaging of the paranasal sinuses of 390 pediatric patients referred over a six-year period in Sakarya and Kocaeli University Faculty of Medicine. Patients were divided into 3 groups as 1-6, 6-12, and 12-18 years old.

Turkish Guideline for Diagnosis and Treatment of Allergic Rhinitis (ART).

Object: To prepare a national guideline for Otorhinolaryngologist who treat allergic rhinitis patients.

Methods: The study was conducted by three authors, namely the writing support team. The support team made the study plan, determined the writing instructions, chose the subgroups including the advisory committee, the advisors for authors and the authors.

The effect of sensory level electrical stimulation of the masseter muscle in early stroke patients with dysphagia: A randomized controlled study.

Background: Dysphagia is a serious cause of morbidity and mortality in stroke patients.

Aims: As the first study in literature, we aimed to evaluate the effects of sensory-level electrical stimulation (SES) to bilateral masseter muscles in early stroke patients with dysphagia.

Settings And Design: This study was conducted at the Physical Medicine and Rehabilitation Clinic of our hospital between 2013 and 2015.

Detection of XRCC1 gene polymorphisms in Turkish head and neck squamous cell carcinoma patients: a comparative analysis with different populations.

Purpose: X-ray repair cross-complementing (XRCC1) is one of the most important genes for the maintenance of genomic integrity and protection of cells from DNA damage. Although tobacco and alcohol consumption are the major risk factors for the development of head and neck squamous cell carcinoma (HNSCC), sequence variation in XRCC1 gene may alter HNSCC susceptibility. Reports on the relationship between HNSCC and polymorphisms in XRCC1 gene have been inconsistent so far.

Association between XRCC3 Thr241Met polymorphism and laryngeal cancer susceptibility in Turkish population.

DNA repair systems are essential for normal cell function. Genetic alterations in the DNA repair genes such as X-ray repair cross-complementing group 3 (XRCC3), can cause a change in protein activity which results in cancer susceptibility. The aim of this study was to investigate the association of XRCC3 Thr241Met single nucleotide polymorphism (SNP), smoking and alcohol consumption with the risk of laryngeal cancer in Turkish population.

How does parental smoking affect nasal mucociliary clearance in children?

Correlation between passive smoking and nasal mucociliary clearance (MCC) in pediatric population has not been reported before. Therefore, in this study, we aimed to investigate the relationship between environmental tobacco smoke and nasal MCC in children whose parents smoke in or outside the house. Three groups of subjects were evaluated: control group (group 1) with 18 children who were not exposed to environmental smoke, 15 passive smokers living with at least one adult household member smoking outside the house (group 2), 17 passive smokers living with at least one adult household member smoking inside the house (group 3).

Paradoxical giant inferior concha.

Anatomic variations of the middle and superior conchae are common, but inferior concha anomalies are rare. These anomalies have included pneumatization, agenesis, and duplication. We describe what we believe is the first reported case of a paradoxical curvature of the bony part of the inferior concha.

[The correlation of vascular endothelial growth factor with angiogenesis and p53 gene in laryngeal squamous cell carcinoma].

Objectives: Angiogenesis is a fundamental process in tumor growth and metastasis. Vascular endothelial growth factor (VEGF) is a key regulator of angiogenesis and it has been identified in a wide variety of malignancies, including head and neck squamous cell carcinoma. However, the regulation of VEGF expression in tumor angiogenesis is not well defined.

[Nasal schwannoma: a report of two cases].

Schwannomas are benign neoplasms arising from Schwann cells of peripheral, cranial and autonomic nerves. Schwannomas of the head and neck comprise 25% to 45% of all schwannomas; however, nasal and paranasal schwannomas account for 4% of these tumors. In this report, two cases of nasal schwannoma are presented.
