The journal is the official online-only publication of Turkish Rhinologic Society and published triannually in April, August, and December. The publication language of the journal is English. European Journal of Rhinology and Allergy aims to contribute to the international literature by publishing original clinical and experimental research articles, case reports, review articles, technical notes, and letters to the editor in the field of rhinology and allergy. The journal's target audience are, researchers, physicians and healthcare professionals who are interested or working in the field of rhinology and allergy.

Simultaneous bilateral choanal and nasopharyngeal stenosis in an adult patient: case report and treatment approach

“…1,9 Additionally, the disadvantages of its use include longer hospitalizations, the need for antibiotics therapy for a long period of time, the possibility of foreign body reaction and pressure necrosis of the columella, as well as trauma to the nasal mucosa resulting in the formation of granulation tissue. 7 Therefore, we decided not to place a nasal stent after permeabilization surgery in the presented case. These adjunct treatments, whether the use of stents or the topical application of mitomycin-C, are still the subject of some controversy and do not have sufficient scientific evidence to be recommended in clinical practice, especially in the adult population, where studies on the treatment of choanal and nasopharyngeal stenosis and atresia are extremely rare.…”

“…Most tend to be congenital, specially choanal stenosis or atresia, and typically present in the first days of life and are treated almost immediately due to the associated breathing difficulties. 7 When these anomalies are acquired, they mainly result from iatrogenic trauma caused by nasal surgeries, oropharyngeal surgeries, and/or nasopharyngeal surgeries. 2 There are several described factors that can precipitate the formation of stenosis after surgical procedures, like patients with a history of keloid formation, excessive postoperative bleeding, postoperative infection, LASER surgery, gastric reflux, excessive resection of posterior tonsillar pillars in adenotonsillectomy, adenoidectomy in conjunction with various palatoplasty techniques, or after excessive electrocautery for bleeding control.…”

Late Diagnosis of Bilateral Choanal Atresia: A Case Report of a Nine-Year-Old Girl

“…At birth, nasal obstruction may be related to neonatal rhinitis, rhino-septal deviations due to obstetric trauma, nasal dysgenesis (stenosis of the piriformis orifice anteriorly, stenosis of the nasal aperture in the middle part, and CA posteriorly), cerebral malposition (meningoceles and meningoencephaloceles), congenital endonasal masses (nasolacrimal cysts, dermoid cysts, nasal hemangiomas), embryonic tumors, or arhinia [5,6]. With an estimated incidence of 1/5000 and 1/7000 births, CA is more rarely bilateral and may sometimes be part of a polymalformative framework, the most frequent of which is CHARGE (colobomas, cardiac (heart) defects, choanal atresia, retardation of growth and cognition, genitourinary anomalies, and ear anomalies) syndrome [1,4,[6][7][8]. Diagnosis should be made immediately after delivery by passing a small rubber catheter through each newborn's nasal cavity to check for patency.…”

Transnasal endoscopic neochoanal technique: An effective procedure for bilateral choanal atresia in adult female

“…Bilateral CA is rarely seen in adults, with only 10 cases reported in the literature [4] , [5] , [9] , [10] . Surgical management of CA consists of transseptal, transpalatal, and transnasal approaches [11] .…”
