Evaluation of the Relationship Between Facial Nerve and Lateral Semicircular Canal in the Posterior Tympanotomy Approach.

Background: To clinically and radiologically evaluate the relationship between the facial nerve and the lateral semicircular canal during posterior tympanotomy.

Methods: Patients who received cochlear implants between 2010 and 2020 were included in the study. The relationship between the facial nerve and the lateral semicircular canal was classified into 3 types by evaluating the axial section computed tomography images.

Automatic Segmentation of Meniscus in Multispectral MRI Using Regions with Convolutional Neural Network (R-CNN).

The meniscus has a significant function in human anatomy, and Magnetic Resonance Imaging (MRI) has an essential role in meniscus examination. Due to a variety of MRI data, it is excessively difficult to segment the meniscus with image processing methods. An MRI data sequence contains multiple images, and the region features we are looking for may vary from each image in the sequence.

Assessment of Vestibular Function in Adults with Prelingual Hearing Loss Using c/oVEMP Tests.

Objectives: The aim of the present study was to compare the vestibular system integrity of individuals with normal hearing with that of prelingual hearing impaired individuals. It is well known that ocular vestibular evoked myogenic potentials (oVEMPs) reflect utricular function, whereas cervical vestibular evoked myogenic potentials (cVEMPs) reflect saccular function. Therefore, oVEMP and cVEMP tests were applied to evaluate the vestibular system integrity of hearing impaired individuals participating in the research.

The role of meteorologic factors and air pollution on the frequency of pediatric epistaxis.

Fluctuations in atmospheric temperature, humidity, and air pollution are associated with the incidence of epistaxis. To date, no study in the literature has evaluated the effect of air pollution and meteorologic conditions on the pediatric population. We aimed to evaluate the effect of meteorologic factors and air pollution on the frequency of epistaxis in children.

[Cochlear implantation in far advanced otosclerosis: series of four cases].

In this article, we present four patients who underwent cochlear implantation due to far advanced otosclerosis. Preoperative evaluations, intraoperative findings, complications, and postoperative benefits were analyzed. Cochlear implantation is a treatment option providing excellent audiological results for rehabilitation of patients with far advanced otosclerosis.

Pediatric Mass Lesions of the Head and Neck Region and Fine-Needle Aspiration Biopsy Results.

Objective: 1. To provide a classification of pediatric mass of the head and neck region and evaluate their frequency. 2.

[Our surgical treatment results in pediatric cholesteatoma].

Objectives: This study aims to evaluate surgical techniques and obtained outcomes in pediatric cholesteatoma.

Patients And Methods: A total of 62 patients (41 males, 21 females; mean age 13 years; range 3 to 17 years) diagnosed as pediatric cholesteatoma between January 1998 and December 2014 were enrolled into the study. Of the patients, canal wall down (CWD) mastoidectomy was performed in 31, canal wall up (CWU) mastoidectomy in 13, inside-out (ISO) mastoidectomy in eight, and tympanoplasty in 10.

Positron emission tomography evaluation of sinonasal inverted papilloma and related conditions: a prospective clinical study.

Objectives: This study aims to determine whether there is a difference between inverted papilloma (IP) and nasal polyp, and squamous cell carcinoma (SCC) with regard to fluorodeoxyglucose uptake.

Patients And Methods: Between September 2007 and May 2014, positron emission tomography computed tomography (PET/CT) images of 27 patients (20 males, 7 females; mean age 53.4 years; range 18 to 74 years), with unilateral polyposis diagnosed on examination and tomographic scans of paranasal sinus were obtained.

Idiopathic incus necrosis: Analysis of 4 cases.

We evaluated ossicular chain reconstruction in patients with idiopathic incus necrosis who have conductive hearing loss and an intact ear drum. The study included four patients (3 women and 1 man; the ages of the patients were 22, 31, 35, and 56 years, respectively) with unilateral conductive hearing loss, no history of chronic serous otitis media, an intact ear drum, normal middle ear mucosa, and necrosis of the long processes of the incus. On preoperative pure tone audiometry, air-bone gaps were 24, 25, 38, and 33 dB.

Sinonasal schwannoma of the middle turbinate.

Paranasal schwannomas are uncommon lesions, representing less than 4% of all head and neck schwannomas. They give rise to nonspecific symptoms such as nasal obstruction, epistaxis, and anosmia. Imaging features are generally nonspecific.

[Utility of fine-needle aspiration biopsy in head and neck masses].

Objectives: We investigated the utility of fine-needle aspiration biopsy (FNAB) for head and neck masses, and compared FNAB results with histopathologic diagnoses.

Patients And Methods: In a group of 352 patients (168 males, 184 females; mean age 44+/-19 years; range 2 to 94 years) who were operated on for head and neck masses, FNAB was performed in 167 patients (47.4%).

Comparison of AlloDerm, fat, fascia, cartilage, and dermal grafts in rabbits.

Objective: To compare various graft materials in the rabbit model, including autologous cartilage, dermal tissue, fat, and AlloDerm (a cadaver-derived material).

Methods: Twenty-five New Zealand white rabbits were used. Equally sized autogenous (fat, fascia, cartilage, and dermal) grafts and AlloDerm were implanted into subcutaneous dorsal pockets on the rabbits.

[Comparison of patients undergoing functional endoscopic sinus surgery combined with septoplasty or septorhinoplasty].

Objectives: We compared patients who underwent functional endoscopic sinus surgery combined with septoplasty or septorhinoplasty and evaluated the concurrent applicability of septorhinoplasty and endoscopic sinus surgery.

Patients And Methods: We retrospectively analyzed 145 patients (96 males, 49 females; age range 16 to 78 years) who underwent endoscopic sinus surgery in conjunction with septoplasty or septorhinoplasty. The two patient groups were compared with respect to demographic characteristics, systemic diseases, allergy histories, the presence of nasal polyposis, preoperative paranasal sinus tomographies, Lund-Mackay scores, surgical procedures, operation times, and complication rates.

[Classic Kaposi's sarcoma of the tongue: a case report].

An 81-year-old male patient presented with a painful mass in the tongue that showed a progressive growth within the past two months. Examination revealed a polypoid mass in the midline of the tongue, purple in color, and 1.5x1.

[Non-Hodgkin's lymphoma of the parotid gland].

Most of the primary malignant lymphomas of the salivary glands originate from the parotid gland. We presented two patients who were admitted with a painless mass in the parotid region and diagnosed to have a lymphoma. Physical examination of a 66-year-old male patient showed a relatively mobile, painless, and firm mass at the inferior aspect of the right parotid gland.

Six cases of Forestier syndrome, a rare cause of dysphagia.

Dysphagia is a common presenting complaint in otolaryngology practice, and there are many causes. Forestier syndrome is a rare cause of dysphagia. It is also known as diffuse idiopathic skeletal hyperostosis (DISH) syndrome or vertebral ankylosing hyperostosis.

Malignant eccrine poroma invading the parotid gland.

Malignant eccrine poroma was first described by Pinkus and Mehregon in 1963. Because of the histologic characteristics of the tumor, these authors concluded that the tumor was likely of eccrine origin. Malignant eccrine poroma originates from the intraepidermal ductal portion of the eccrine gland.
