Symptoms and Treatment of Choanal Atresia - Stenting Remains Controversial.
Summary of "Symptoms and Treatment of Choanal Atresia - Stenting Remains Controversial."
Congenital choanal atresia is a rare malformation of the upper airways occurring sole or within the scope of syndromes. The controversy regarding standardized surgical approach and optimal technique preventing re-stenosis as well as the proceeding in case of a unilateral malformation persists. To address these issues, a retrospective analysis of patients presenting with choanal atresia in our department within the last 10 years was performed. 15 infants aged 3 days to 13 years (mean 42 months) who presented with unilateral (10 cases) and bilateral (5 cases) choanal atresia underwent surgical repair. 4 patients failed previous surgeries. All interventions were performed in transnasal endoscopic technique. 7 patients were intraoperatively stented for 6 weeks, 4 patients for 1 week. In 73% (11 out of 15 children) further congenital anomalies were identified. In 7 cases a re-stenosis requiring treatment occurred, predominantly in long-term stented patients. No intra- or postoperative hemorrhages or infections occurred. To provide an adequate work-up of affected patient including a screening for further congenital anomalies, a multidisciplinary approach is required. Endonasal endoscopic approach represents a safe technique for surgical repair of choanal atresia. The indication for surgical repair in case of a unilateral atresia is based on the severity of clinical symptoms. The use of stents, especially of long term, remains controversial and needs further evaluation.

Medical and Biotech [MESH] Definitions
A congenital abnormality that is characterized by a blocked CHOANAE, the opening between the nose and the NASOPHARYNX. Blockage can be unilateral or bilateral; bony or membranous.
Rare disease characterized by COLOBOMA; CHOANAL ATRESIA; and abnormal SEMICIRCULAR CANALS. Mutations in CHD7 protein resulting in disturbed neural crest development are associated with CHARGE Syndrome.
Gb Virus C
A species of virus (unassigned to a genus) in the family FLAVIVIRIDAE. It is genetically heterogeneous, of human origin, and transmitted by blood or blood products. Despite its alternate name (Hepatitis G virus), its pathogenicity remains controversial.
Antley-bixler Syndrome Phenotype
An inherited condition characterized by multiple malformations of CARTILAGE and bone including CRANIOSYNOSTOSIS; midface hypoplasia; radiohumeral SYNOSTOSIS; CHOANAL ATRESIA; femoral bowing; neonatal fractures; and multiple joint CONTRACTURES and, occasionally, urogenital, gastrointestinal or cardiac defects. In utero exposure to FLUCONAZOLE, as well as mutations in at least two separate genes are associated with this condition - POR (encoding P450 (cytochrome) oxidoreductase (NADPH-FERRIHEMOPROTEIN REDUCTASE)) and FGFR2 (encoding FIBROBLAST GROWTH FACTOR RECEPTOR 2).
Inflammation of the thick tissue on the bottom of the foot (plantar fascia) causing HEEL pain. The plantar fascia (also called plantar aponeurosis) are bands of fibrous tissue extending from the calcaneal tuberosity to the TOES. The etiology of plantar fasciitis remains controversial but is likely to involve a biomechanical imbalance. Though often presenting along with HEEL SPUR, they do not appear to be causally related.
Objective of this study is to evaluate the efficacy and safety of using stents after endoscopic repair of bilateral posterior choanal atresia. Twenty cases of congenital bilateral posterior choanal at...
Introduction: We report the first published description of transoral use of the transnasal flexible laryngoesophagoscope during surgical correction of choanal atresia. Case report: A four-month-old bo...
This study aimed to evaluate the long-term outcomes of endonasal surgical treatment for choanal atresia (CA) and determine possible predictors of recurrence. A retrospective study of 50 cases of CA th...
Minimal invasive treatment (called "endovascular") of the arteries of the lower limb remains problematic, because recurrent disease ("restenosis") frequently leads to recurrent symptoms. A...
Biliary atresia and idiopathic neonatal hepatitis are the most common causes of jaundice and hyperbilirubinemia that continue beyond the newborn period. The long term goal of the Biliary...
Biliary atresia is a congenital disorder of bile duct development or destruction of established but immature bile ducts. The study tests the hypothesis that post-operative steroids improv...
The researchers hypothesize that emergency contraception (EC) will initiate the changes associated with atresia or ovulatory failure at all stages of follicular development and that the im...
Little is known about the factors that cause biliary atresia nor the factors that influence disease progression. The purpose of this study is to collect the pertinent clinical information,...
