1/16. Treatment of a recurrent choanal atresia by balloon dilatation.A 16-year-old female patient with recurrent stenosis after unilateral choanal atresia that had been treated by surgery and laser therapy presented with restenosis 3 weeks after laser resection. As an alternative to repeat surgery, she was treated by balloon dilatation. Four balloon dilatations were performed (three at 4-week intervals and the last after an 8-week interval) over a 4-month period on an outpatient basis. She tolerated the treatment well without any complications. Over a follow-up period of 2 years the choana has remained completely open. The balloon dilatation described in this context here for the first time may be a good alternative to repeated operations in the treatment of recurrent choanal atresia, with minimal stress to the patient.- - - - - - - - - - ranking = 1keywords = atresia (Clic here for more details about this article) |
2/16. Assessment of congenital bony nasal obstruction by 3-dimensional CT volume rendering.The nature and extent of congenital bony nasal obstruction is best determined by X-ray computed tomography (CT) imaging. Three-dimensional volume rendering of CT images provides an integrated perspective that can assist in clinical decision making and in operative planning. Clinical cases of choanal atresia and pyriform aperture stenosis are reviewed with their images. The authors propose this modality as an evolving standard for imaging of congenital bony nasal obstruction.- - - - - - - - - - ranking = 0.16666666666667keywords = atresia (Clic here for more details about this article) |
3/16. Unilateral rhinorrhea and nasal obstruction in an adult.BACKGROUND: choanal atresia is an uncommon malformation, consisting of congenital blockage of one of both choanae. Symptomatology varies according to the type of atresia and the age of the patient. The bilateral, or complete, form presents in newborns as respiratory distress while unilateral, or incomplete, forms present in older children or adults. CASE REPORT: a 16-year-old girl presented with a lifelong history of right-sided nasal blockage and unilateral watery rhinorrhea. The rhinorrhea increased when the patient bent her head forward. Treatment with antihistamines and topical nasal corticosteroid sprays produced little improvement. The patient's previous medical history was unremarkable except for the expulsion of a coagulated mass through the right nostril a few days after birth, and event that provoked her symptoms. physical examination was normal except for excoriation of the right external nasal margin. Anterior rhinoscopy revealed watery rhinorrhea, erythematous mucosa in the right nasal cavity and deviated nasal septum. No nasal masses or polyps were found. physical examination confirmed the absence of ventilation in the right nasal airway and nasal endoscopy indicated right choanal obstruction. Diagnostic test: skin prick tests with aeroallergens were positive for grass pollen and negative for all other allergens tested (mites, moulds, latex, and epithelia). Total IgE was normal (9 IU/ml). No eosinophilia was detected in the nasal secretion specimen. The results of laboratory tests including complete blood count and differential, erythrocyte sedimentation rate, and biochemical parameters were normal. The glucose level in nasal secretion was 4.6 mg/dl. x-rays of the paranasal sinuses and cavum showed no anomalies. Axial fine-cut computed tomography scans (3 3 mm) revealed choanal obstruction with bony and membranous components. CONCLUSIONS: a diagnosis of congenital choanal atresia should be considered in cases of unilateral blockage and rhinorrhea. Nasal endoscopy and computed tomography scans are essential to establish diagnosis.- - - - - - - - - - ranking = 0.5keywords = atresia (Clic here for more details about this article) |
4/16. Bilateral congenital choanal atresia in a 13-year-old patient.Congenital choanal atresia (CCA) is the developmental failure of the nasal cavity to communicate with the nasopharynx. Surgical repair is recommended in the first weeks of life in bilateral cases, because in newborns this is a life-threatening situation. This is a case report of a 13-year-old patient complaining of long-term bilateral nasal obstruction and rhinorrea, in whom bilateral choanal atresia was diagnosed by endoscopic exploration and CT scan, and who was treated by an endonasal endoscopic surgical technique. Bilateral choanal atresia is a life-threatening disease in newborns; however, it can be diagnosed in adults with bilateral nasal obstruction and rhinorrea.- - - - - - - - - - ranking = 1.1666666666667keywords = atresia (Clic here for more details about this article) |
5/16. choanal atresia: an unusual serious complication of complementary and alternative medical treatment.The use of complementary and alternative medicine (CAM) is common among patients with chronic, long-standing nasal disease. Complications resulting from inappropriate CAM practices are sometimes reported, but serious complications such as choanal atresia and stenosis are rare. We report a case of choanal atresia and stenosis due to herbal drug (ie, chemical) cauterization of the nasal cavity in a 39-year-old man. We reviewed the literature on why patients previously given conventional treatment seek alternative therapies. The patient underwent surgical intervention to relieve choanal atresia and stenosis. The postoperative course was unremarkable, and follow-up for 1 year revealed no evidence of restenosis. choanal atresia and stenosis resulting from CAM treatment are rare. Otolaryngologists should be aware of possible complications occurring in patients receiving such treatments.- - - - - - - - - - ranking = 1.3333333333333keywords = atresia (Clic here for more details about this article) |
6/16. Congenital salivary gland anlage tumor of the nasopharynx.OBJECTIVE: Nasal and upper respiratory tract obstruction in the neonatal period can result from a variety of conditions, and may present with variable symptoms. In the absence of dysmorphic features or other abnormalities, causes of nasal obstruction may be difficult to differentiate on initial examination. We report an unexpected and potentially life-threatening condition arising during the work-up of this common neonatal complaint. DESIGN: Case report with literature review. RESULTS: A male neonate presented with complaints of nasal obstruction and feeding difficulties. A common diagnostic approach to neonatal nasal obstruction was performed, resulting in an unexpected and potentially life-threatening, albeit curative, result. Cannulation of the nasal cavity to rule out choanal atresia resulted in a burst of bleeding from the nose and mouth. A finger sweep of the oropharynx produced a dislodged mass lesion. pathology revealed a salivary gland anlage tumor of the nasopharynx. CONCLUSIONS: The diagnosis of a nasopharyngeal mass lesion should be considered in neonates with nasal obstructive symptoms. It is wise to place an index finger in the oropharynx when passing catheters to rule out choanal atresia to feel a dislodged mass lesion before it can become an airway foreign body. Should passage of nasal catheters result in bleeding and/or respiratory distress, the possibility of a displaced mass lesion must be considered immediately to institute prompt intervention.- - - - - - - - - - ranking = 0.33333333333333keywords = atresia (Clic here for more details about this article) |
7/16. Technique for fabrication of splint preventing postsurgical restenosis in choanal atresia.choanal atresia, a congenital narrowing or obstruction of the nasal airway caused by significant respiratory distress in neonates, may require emergency intervention. Although atresia can be repaired surgically, restenosis is a common complication with this procedure. To prevent this, tubes are inserted into the nasal cavity immediately after surgery. This article describes a technique for preparing individual surgical splints designed to prevent postsurgical obstruction of the nasal cavity.- - - - - - - - - - ranking = 1keywords = atresia (Clic here for more details about this article) |
8/16. Bilateral choanal atresia in an adult: is it compatible with life?Bilateral choanal atresia is potentially life-threatening. The condition almost always presents in the new born, with alternating phases of respiratory distress and apnoea relieved by crying. We report a rare case of bilateral choanal atresia presenting for the first time at 22 years of age. The patient had no features of cyanosis or apnoea, presenting only with bilateral nasal obstruction, rhinorrhoea and anosmia. His neonatal history was unremarkable. No syndromic association was noted excepting for telecanthus. The presence of bony atresia was confirmed on computed tomography (CT) scan and transnasal endoscopic surgery was used to obtain a patent airway. This case is a rare report of bilateral choanal atresia presenting for the first time in adult life.- - - - - - - - - - ranking = 1.3333333333333keywords = atresia (Clic here for more details about this article) |
9/16. Coexistence of choanal atresia and Tessier's facial cleft number 2.choanal atresia is one of the most commonly observed congenital abnormalities of the nose. This defect is frequently associated with other congenital anomalies. One of the anomalies, which is rarely encountered is a Tessier's facial cleft 2. In this report, we present a 6-year-old girl who was brought to our department with complaints of nasal obstruction and chronic nasal discharge. On examination, a scar was seen on the left ala of her nose due to the former repair of a congenital defect. We found hypoplastic nasal cavities and bilateral choanal atresia demonstrated by rigid and flexible endoscopy. A CT scan supported these findings. This coexistence of bilateral choanal atresia with a number 2 facial cleft is an addition to a formerly proposed classification of laterofacial clefts. We think that this classification is better for describing the extent and origin of these complex lesions.- - - - - - - - - - ranking = 1.1666666666667keywords = atresia (Clic here for more details about this article) |
10/16. Congenital nasal pyriform aperture stenosis.The congenital stenosis of pyriform aperture is an unusual cause of neonatal nasal obstruction. It is due to bony overgrowth of the nasal lateral process of the maxilla. Initially this narrowest part of nasal airway was considered an isolated deformity; subsequently the congenital Stenosis of pyriform aperture was thought to represent a microform of holoprosencephaly. In this report a male neonate had respiratory distress, cyclic cyanosis and apnea after delivery. The patient underwent surgical correction of pyriform stenosis by sublabial access. In the follow up, the patient had good evolution. The report of this deformity shows an important cause of neonatal nasal obstruction and its differential diagnosis with bilateral choanal atresia. Congenital stenosis of nasal pyriform aperture can be surgically corrected when necessary.- - - - - - - - - - ranking = 0.16666666666667keywords = atresia (Clic here for more details about this article) |
