Oropharyngeal Hairy Polyp Causing Dysphagia

Hairy polyp is a rare, benign tumor that comprises ectodermal and mesodermal germ layers. The embryogenesis of hairy polyp is precisely unknown, and concurrently, it has a female predominance. Although hairy polyp is observed in every part of the body; it is frequently located in the nasopharynx and oropharynx. Respiratory distress and feeding difficulties are the most related symptoms. Differential diagnoses comprise hemangioma, teratoma, epidermoid cyst, neuroblastoma, and meningocele. In this report, a seven-year-old patient who was admitted to our clinic with swallowing difficulty because of an oropharyngeal hairy polyp was described

False-Positive Laryngeal FDG Uptake During PET/CT Imaging: Reinke’s Edema

Positron emission tomography/computed tomography (PET/CT) is frequently used for diagnosing, staging, and following-up various malignancy types because it provides information on the site and metabolic activity of the tumor. Fluorodeoxyglucose (FDG) uptake by the normal laryngeal tissue is symmetric and low, whereas that under some non-malignant conditions of the larynx, such as vocal cord paralysis and Teflon granuloma, is asymmetrically increased. We reported the first case of histologically proven Reinke’s edema causing false-positive laryngeal FDG uptake on PET/CT imaging. A clinician must be aware of these rare benign lesions in the case of increased FDG uptake, and histopathological investigation is mandatory to rule out malignancy for suspicious cases

Nonodontogenic mandibular lesions: differentiation based on CT attenuation

Mandibular lesions are classified as odontogenic and nonodontogenic based on the cell of origin. Odontogenic lesions are frequently encountered at head and neck imaging. However, several nonodontogenic pathologies may also involve mandible and present further diagnostic dilemma. Awareness of the imaging features of nonodontogenic lesions is crucial in order to guide clinicians in proper patient management. Computed tomography (CT) may provide key information to narrow diagnostic considerations. Nonodontogenic mandibular lesions may have lytic, sclerotic, ground-glass, or mixed lytic and sclerotic appearances on CT. In this article, our aim is to present various nonodontogenic lesions of the mandible by categorizing them according to their attenuations on CT

Papillary Thyroid Carcinoma Spreading into Branchial Cleft Cyst

Papillary thyroid carcinoma (PTC) is the most common type of thyroid malignancy and it can cause cystic metastasis to the neck region. Branchial cleft cysts (BCCs) are among the most commonly encountered congenital cystic neck masses. PTC metastasis into BCC has been rarely reported in the literature. In this case report we report a patient presenting with a cystic neck mass for which fine needle aspiration biopsy was reported as benign cytology and eventually was diagnosed as PTC metastasis to the BCC. The importance of investigating the thyroglobulin levels in fine needle aspiration materials of cystic neck masses for early diagnosis of possible PTC metastasis is specifically emphasized

Hairy Polyp of the Supratonsillar Fossa Causing Intermittent Airway Obstruction

Introduction Dermoids frequently called “hairy polyps” and their nature have not been completely clarified. Objectives To discuss the unusual presentation, symptoms, incidence, histology, and perioperative management of hairy polyps in the light of a case and current literature. Resumed Report A 3-year-old boy presented with intermittent respiratory distress since birth. Oropharyngeal examination revealed a nasopharyngeal mass originating from the supratonsillar fossa. The mass was so mobile that it moved between the oropharynx and the nasopharynx during swallowing. The radiologic and pathologic examinations confirmed the mass as a hairy polyp. Conclusion In a pediatric age group with airway obstruction, hairy polyps of the oropharyngeal region must also be included in the differential diagnosis

Evaluation of the relationship between nasal septal deviation and development of facial asymmetry with anthropometric measurements depending on age

Aim: It was aimed to determine the change of facial asymmetry resulting from nasal septal deviation (SD) depending on age, gender, degree of deviation and the affected area besides the effect of SD on somatotype and craniofacial morphology. Materials and methods: 171 volunteers (90 males, 81 females), 27 individuals aged 9-13, 44 individuals aged 14-18, 44 individuals aged 19-23 and 56 individuals in control group participated in the study conducted in otorhinolaryngology polyclinic.11 photometric, 16 anthropometric measurements were taken from the participants. Results: SD affects facial asymmetry formation, although not statistically significant compared to healthy individuals asymmetry rates (p>0.05). It was determined that the degree of SD affected asymmetry only between the ages of 14-18 (in adolescence) and the development of asymmetry in all SD patients was not statistically dependent on age and gender (p>0.05). Photometric measurements demonstrated asymmetries in horizontally-extending parameters of 1/3 middle part of face. There was no statistically significant difference in the cranial anthropometric measurements of the upper and lower 1/3 of the face compared to the control group (p>0.05). The order of the most asymmetrical parameters is Alare-Zygion, Alare-Subnasale, Cheilion-Gonion, Exocanthion-Cheilion, Midsagittal plane-Zygion, Zygion-Cheilion, Zygion-Gonion, Subalare-Cheilion, Glabella-Exocanthion. In all participants were determined that endomorph somatotype was dominant in female and mesomorph somatotype was dominant in male besides SD did not affect somatotype and somatotype did not alter with age. Conclusion: The development of facial asymmetry due to SD is not affected by age and gender furthermore SD does not affect craniofacial asymmetry and somatotype

Cochlear electrophysiology and histopathology of rats exposed to intratympanic silica nanoparticles

WOS:000497661000015Toxic effects of silica nanoparticle of rats exposed intratympanically for 7 days were investigated using brainstem auditory evoked potential and distortion product otoacoustic emission techniques. The histopathological changes were evaluated with light microscopy and field emission-scanning electron microscopy were demonstrated in cochleas using based energy-dispersive X-ray spectroscopy. The reduction in the amplitude and prolongation at the peak latency and interpeak latencies of brainstem auditory evoked potential were observed. Silica nanoparticles significantly reduced distortion product otoacoustic emission amplitude in the 2, 3 and 4 kHz frequencies. In the light microscopic evaluation, the samples obtained from the experimental group showed a significant loss of hair cells. Field emission scanning electron microscope analysis of experimental group showed considerable hair cell damage compared to control group. The findings of this study show that intratympanic administration of silica nanoparticles may lead to hearing impairment by causing structural changes in cochlear hair cells.Research Fund of Mersin University in TurkeyMersin University [BAP- 2017-1-TP2-2143]This study was supported by the Research Fund of Mersin University in Turkey with Project Number: BAP- 2017-1-TP2-2143
