Item Respiratory problems and associated factors following endoscopic balloon dilatation procedure in children with acquired subglottic stenosis(2022) Tuzuner, Arzu; Bas, Ceren; Jafarov, Sabuhi; Bahcecitapar, Melike; Aydin, Erdinc; 0000-0002-7302-4199; 35037169; AAI-8044-2021Objectives Endoscopic balloon dilatation (EBD) offers a safe and non-invasive surgical option for the treatment of subglottic stenosis. Patient selection is important to achieve good results and to detect which patients are more prone to the development of complications. The aim of this study was to determine predictors of postoperative problems and early complications in primary EBD surgeries. Methods A retrospective analysis was made of patients with acquired subglottic stenosis who were operated on with the EBD technique between January 2010 and December 2019 in the Otolaryngology-Head and Neck Surgery Department of Baskent University Hospital. Demographic data including the age and sex of the patients were collected together with etiology, presence of chromosomal or craniofacial anomaly (C/CA), duration of prolonged intubation (DPI), and extubation dilatation timeframe (EDT). Intra and postoperative follow-up data were recorded of the need for intubation or tracheotomy, development of desaturation, and grade and type of stenosis. Results The male to female ratio was 2:1. The patients comprised 42 males and 22 females with a mean age of 296.52 +/- 551.93 days. The cause of prolonged intubation was surgery for congenital heart disease in 50 (78.1%) patients and prematurity in 14 (21.9%). The type of lesion was acute granulation in 44 (72.1%) and chronic granulation in 17 (27.9%) patients. C/CA was determined in 13 patients, the mean grade of stenosis was 76.33 +/- 15.21%, mean DPI was 25.25 +/- 35.49 days, and mean EDT was calculated as 78.23 +/- 373.82 days. Desaturation following endoscopic balloon dilatation developed in 26 (40.6%), orotracheal intubation was required in 10 (15.6%), tracheotomy in 10 (15.6%), and cardiopulmonary arrest occurred in 4 (6.25%). Prematurity, a longer duration of preoperative intubation, longer time from extubation to dilatation, older age, and higher grade of stenosis were determined as factors associated with postoperative early respiratory complications. Conclusion EBD indication should be carefully considered in children with acquired subglottic stenosis. To achieve better results and minimise complications, EBD should be performed without delay.Item Vestibular Illusions and Alterations in Aerospace Environment(2021) Demir, Abdurrahman Engin; Aydin, Erdinc; 0000-0001-6864-7378; 34386801; AAJ-2379-2021As the aerospace industry has grown rapidly over the years, aviators and astronauts have been exposed to some abnormal physiological changes arising from the dynamics of the aerospace environment. The vestibular system, encoding linear and angular movements of the head, is one of the main affected systems in which those abnormal changes can occur during flight. Despite the intricate and solid organization, vestibular units are such delicate structures that they can easily be deceived by aerial dynamics and gravity changes. Therefore, it is of vital importance for the continuity of flight safety to be aware of the detrimental alterations and impairments regarding the vestibular system and its reflex pathways. The aim of this paper was to present a review about how a healthy vestibular system is negatively affected within the aerospace environment and how some vestibular disorders become exaggerated or impaired during aviation and space activities.Item Assessment of Parotid and Submandibular Glands With Shear Wave Elastography Following Radioactive Iodine Therapy for Papillary Thyroid Carcinoma(2019) Rahatli, Feride Kural; Turnaoglu, Hale; Iyidir, Ozlem Turhan; Kirnap, Nazli Gursoy; Haberal, Kemal Murat; Aydin, Erdinc; Uslu, Nihal; 0000-0001-5305-6807; 0000-0002-8211-4065; 30027680; K-7904-2019; R-9398-2019; ABC-5258-2020Objectives Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy. Radioactive iodine (RAI) therapy is used for remnant ablation following thyroidectomy. Side effects such as dysphagia, xerostomia, and sialoadenitis may occur. We aimed to determine the differences in the parotid and submandibulary glands between healthy patients and patients with PTC who had undergone RAI therapy and have dry mouth symptoms using both shear wave elastography and ultrasonography. Methods We enrolled 30 patients with PTC who had undergone RAI therapy following surgery and 30 healthy controls. Ultrasonography and shear wave elastography of submandibular and parotid glands were performed. The volume of the submandibular glands and the thickness of parotid glands were determined. Ten independent measurements were obtained from each gland, with the region of interest placed at different points on the glands. The mean shear wave velocities (SWVs) were calculated and compared between the patients and controls. Results In the PTC group, there was a significant reduction in the volume of the submandibular glands (P < .05) and in the thickness of the parotid glands (P < .05) compared with the control group. The mean SWVs of the parotid glands and submandibular glands were significantly higher in the PTC group compared with the control group (P < .0001). The SWVs of the parotid glands were higher than the SWVs of the submandibular glands (P < .0001). Conclusions Shear wave elastography could be a noninvasive and easy assessment method of parotid and submandibular glands in patients who had undergone RAI therapy and experience dry mouth.Item Lingual Tonsil Hypertrophy in Patients With Allergic Rhinitis(2019) Coban, Kubra; Koycu, Alper; Aydin, Erdinc; 0000-0003-1290-3509; 31522521Background Lingual tonsils, part of the Waldeyers' Ring, are located in base of the tongue. They are commonly observed in childhood, due to increased immunological activity. Several factors such as laryngopharyngeal reflux, younger age, smoking, and obesity are associated with hypertrophy of lingual tonsils (LTH) in adulthood. However, the relation between allergic rhinitis and LTH is not clearly highlightened in the literature so far. Objective To investigate the role of allergic rhinitis in the development of LTH. Methods Adult patients who were diagnosed with allergic rhinitis were included in the study group. The control group consisted of age- and sex-match healthy volunteers. Complete otorhinolaryngology examination including fiberoptic endoscopic evaluation was performed to both groups. Blood samples were obtained for total immunglobulin E levels, and skin prick tests were performed to both groups. Patients with allergy complaints and positive skin prick tests were included in the study group, while healthy volunteers with negative skin prick tests were enrolled in the control group. The grading for LTH was achieved by a physician who was blind to the study. Results The incidence of LTH was significantly higher in the study group when compared to the control group (P = .001). Similarly, the incidence of grade 3 LTH was significantly higher in the study group compared to the controls (P = .002). Conclusion According to our results, LTH is more frequently observed in patients with allergic rhinitis. Grade 3 representing larger LTH is more commonly seen in patients with allergic rhinitis.Item Proliferating Trichilemmal Tumor of the Auricula: A Very Rare Locus(2019) Coban, Kuebra; Akkaya, Hampar; Aydin, Erdinc; 31750191Proliferating trichilemmal tumor (PTT) is a rare but morphologically characteristic tumor, derived from the external root sheath. They are commonly localized as a solitary lesion on the scalp. They rarely occur in other regions. PTTs generally behave in a benign fashion, up to 20% of the lesions may undergo malignant transformation into squamous carcinoma. We present an elderly woman with a cystic swelling on the crus of auricular helix diagnosed as PTT. To our knowledge, this is the first case in the English literature, of PTT of the auricula.
