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 The Impact of Serum 25-Hydroxyvitamin D3 Levels on Allergic Rhinitis(2019) Coban, Kubra; Oz, Isilay; Topcu, Deniz Ilhan; Aydin, Erdinc; 0000-0002-1219-6368; 31569970; E-3717-2019We aimed to clarify the relation between allergic rhinitis and the serum levels of 25-hydroxivitamin D in the adult population. The study group consisted of 86 patients with allergic rhinitis who were diagnosed with the help of history of allergy, positive signs for allergy, blood samples, and positive skin prick tests; while the control group included 43 age- and sex-matched healthy volunteers with negative skin prick tests. The demographic data, medical history, findings in the physical examinations, serum levels of total immunoglobulin E (IgE) and 25-hydroxyvitamin D, and skin prick test results of the groups were noted. A total of 129 patients fulfilling the necessary criteria were enrolled. The median serum 25-hydroxyvitamin D levels in the study group were significantly lower compared to the control group (P= .014). In the study group, median serum vitamin D levels were significantly higher in men, compared to women (P= .03). There was a significant negative correlation between IgE and vitamin D levels in the allergic rhinitis group (P= .028,r= -0.246). This study showed that patients with allergic rhinitis might be more vulnerable to have lower serum levels of vitamin D. Thus, vitamin D supplementation as an adjunctive therapy may be considered in those patients.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.Item Benign Paroxysmal Positional Vertigo After Nonotologic Surgery: Case Series(2015) Kansu, Leyla; Aydin, Erdinc; Gulsahi, Kamran; 25838683Benign paroxysmal positional vertigo is one of the most common types of vertigo caused by peripheral vestibular dysfunction. Although head trauma, migraine, longterm bed rest, Menie're disease, viral labyrinthitis, and upper respiratory tract infections are believed to be predisposing factors, most cases of benign paroxysmal positional vertigo are idiopathic. Ear surgery is another cause, but after nonotologic surgery, attacks of benign paroxysmal positional vertigo are rare. We describe three cases of benign paroxysmal positional vertigo attacks after non-otologic surgery (one patient after a nasal septoplasty and two patients after dental endodontic treatment) and discuss the pathophysiological mechanismof benign paroxysmal positional vertigo seen after non-otologic surgery, its diagnosis and treatmentItem Sex differences in adult craniofacial parameters(2015) Avci, Suat; Ergun, Tarkan; Aydin, Erdinc; Kansu, Leyla; 25935592To compare normal male and female craniofacial parameters in adults and evaluate associations of sex and intercochlear distance with other craniofacial parameters. In 60 normal adults (30 men and 30 women) who had no otitis media, craniofacial parameters were measured retrospectively on two-dimensional reformatted computed tomography scans. Compared with women, men had significantly greater mean osseous auditory tube length, cartilaginous auditory tube length, mastoid length, intercochlear distance, sella to posterior nasal spine distance, sella to basion distance, and nasopharynx sagittal area. The intercochlear distance was significantly correlated with mastoid depth, midpoint of the pharyngeal opening distance, sella to nasion distance, and nasopharynx sagittal area and inversely with angle of the auditory tube. Most men and women had Korner septum present, and mean thickness of Korner septum was significantly greater in men than women. Some craniofacial parameters, especially vertical parameters, differ with sex. These differences begin in childhood and continue in adulthood. Sex must be considered when planning a craniofacial morphologic study, and results of a craniofacial morphologic study should be evaluated with caution when there is no sex matching of the patient and control groups.Item Recurrent Pleomorphic Adenoma of the Submandibular Gland(2016) Inan, Serhat; Aydin, Erdinc; Babakurban, Seda Turkoglu; Akcay, Eda Yilmaz; 0000-0001-6864-7378; 0000-0001-6831-9585; 0000-0001-5067-4044; 29392015; AAJ-1407-2021; AAJ-2379-2021; AAK-1960-2021; AAI-8856-2021Pleomorphic adenoma (PA) is the most common benign tumor of salivary glands. Most PAs occur in the parotid (80%), followed by the submandibular gland (10%) and minor salivary and sublingual glands (10%). Submandibular gland PAs usually manifest in the submandibular area as a painless hard mass. Although several recurrent parotid gland PA cases have been reported in the literature, recurrent submandibular gland PA is quite rare. Complete surgical removal of tumor of the submandibular gland and keeping the capsule intact are important to prevent recurrence. Here we present a rare case of submandibular gland PA recurrence that occurred 5 years after the first surgery and methods to prevent recurrence.Item A Rare Cause of Hemifacial Spasm: Papillary Oncocytic Cystadenoma(2016) Erol, Ozan; Aydin, Erdinc; 0000-0001-6864-7378; 27761290; AAJ-2379-2021Background: Hemifacial spasm is a sudden, involuntary and synchronous spasm of the facial muscles. The most frequent cause of this condition is compression of the facial nerves due to vascular pathologies. The most commonly used method of treatment is Botulinum toxin injection. However, the gold standard treatment is surgical treatment. Case Report: A 64-year-old male patient with hemifacial spasms, which had occurred due to a rare parotid mass that had been surgically treated, is presented in this case. Conclusion: This case report demonstrates that long-standing parotid gland masses may compress the facial nerves and cause demyelination in the nerve and thus may cause spasms in the facial muscles.
