Evaluation of Olfactory Function With Objective Tests in COVID-19-Positive Patients: A Cross-Sectional Study.

Objective: Olfactory dysfunction is relatively high in coronavirus disease 2019 (COVID-19) patients. The aim of this study is to investigate the incidence of olfactory disorder objectively in patients with laboratory-confirmed COVID-19 infection.

Material And Method: The study included 31 healthy controls and 59 COVID-19 patients who were diagnosed and treated in the COVID departments in a tertiary hospital.

Report of a case of malignant peripheral nerve sheath tumor of the neck with an early local recurrence.

Malignant peripheral nerve sheath tumor (MPNST), which originates in Schwann cells, is uncommon in the head and neck. These highly aggressive sarcomas are characterized by local recurrence and distant metastasis. Many are associated with neurofibromatosis type 1; the survival rate in such cases is poorer than the rate associated with tumors that arise de novo.

Unusual manifestations of bilateral carotid artery dissection: Dysphagia and hoarseness.

Dissection of the carotid artery can occur intracranially or extracranially, although dissections tend to affect extracranial segments of the arteries much more commonly than intracranial segments. Carotid artery dissection (CAD) is most common in middle-aged women. Although not completely known, the main risk factors related to carotid artery dissection are genetic and environmental factors, traumatic events, cervical manipulation, migraine, recent infections, hyperhomocysteinemia, and hereditary connective tissue disorders.

A difficult case: sarcoidosis of the middle ear.

Sarcoidosis is a common multisystemic granulomatous disorder affecting several organs and tissues. However, the respiratory tract is the region commonly involved in more than 90% of patients, and the middle ear is a direct extension of it. In spite of this, direct middle ear and/or mastoid involvement of sarcoidosis is more rarely seen.

Detection of HHV-8 and HPV in laryngeal carcinoma.

Objective: In this study we aimed to investigate the presence of human herpesvirus 8 (HHV-8) and human papillomavirus (HPV) in laryngeal carcinoma.

Materials And Methods: Fifty patients operated on because of laryngeal carcinoma were included in the study. Forty-seven had squamous cell carcinoma (SCC) whereas three had verrucous carcinoma.

Variables affecting the occurrence of gastroesophageal reflux in obstructive sleep apnea patients.

A number of recent studies have suggested that apnea and/or hypopnea episodes may be in a causal relationship with nocturnal gastroesophageal reflux (GER) episodes in obstructive sleep apnea (OSA) patients. In this study, we addressed the possible factors that may affect the occurrence of reflux events in OSA patients. For this reason, we investigated respiratory and sleep parameters in OSA patients with or without nocturnal GER episodes.
