Analysis of the Correlation of the Lamina Papyracea-to-Midline Distance with the Location of Anterior Ethmoidal Artery and Keros Classification.

Unlabelled: The aim of the study was to investigate the relations between anatomical structures that are susceptible to inadvertent injuries during the surgery using preoperative computed tomography (CT) scans. 153 CT scans were reviewed and the distance from the lamina papyracea (LP) to the midline and the distance of the anterior ethmoidal artery (AEA) to the skull base were measured bilaterally. Also, the depth of olfactory fossa was measured and categorized using the Keros classification.

Correlation of olfactory dysfunction with lung involvement and severity of COVID-19.

Background: Olfactory dysfunction (OD) is a significant symptom of COVID-19 and may be the earliest symptom, or it may sometimes be the only manifestation of the disease.

Aims: To investigate whether OD is correlated with chest computed tomography (CT) findings, blood test parameters, and disease severity in COVID-19 patients.

Methods: The files of COVID-19 patients were retrospectively reviewed, and the ones who had information about smelling status and CT were taken into consideration.

The levels of advanced oxidation protein products in patients with obstructive sleep apnea syndrome.

Background: Obstructive sleep apnea syndrome (OSAS) is characterized by repeated episodes of complete or partial obstructions of the upper airway during sleep, frequently followed by transient hypoxemia. Advanced oxidation protein products (AOPP) are a family of oxidized protein products, and oxidative stress has a substantial role in the morbidity of OSAS.

Aims: The aim of this study was to investigate the serum levels of advanced oxidation protein products (AOPP) as a marker of oxidative stress, and their correlation with polysomnographic parameters in patients with obstructive sleep apnea syndrome (OSAS).
