Filter by:Nasopharyngeal carcinoma (NPC) occurs at a high frequency in southern China, northern Africa, and Alaska, with a reported incidence of 30 cases per 100 000 in Guangdong Province. Endoscopic examination and biopsy are the main methods used for detection and diagnosis of NPC. Early NPC patients achieve favourable prognoses after concurrent radiotherapy and chemotherapy in compassion with advanced NPC patients. Here, the investigators focused on the utility of artificial intelligence to detect early NPC, which based on white light imaging (WLI) and Narrow-band imaging (NBI) nasoendoscopic examination. Having access to this unique population provides an unprecedented opportunity to investigate the effect of intelligent system on diverse nasopharyngeal lesions detection and develop a novel Computer-Aided Diagnosis System.
Congenital choanal atresia is an abnormality of the posterior nasal passages resulting in complete or partial obstruction of the nasal airways. It has an incidence of 1: 5000 to 8000 live births, with a female predominance. 41% - 72% occur in conjunction with non-syndromic facial abnormalities such as arched palate, cleft lip, and auricular deformities. About 4% present as a component of chromosomally-based syndromes such as (coloboma, heart defect, atresia choanae, retarded growth, genital abnormality, and ear abnormality" and Treacher Collins syndromes. Previous reports have described the ratio of bony to membranous choanal atresia as 9:1. However, a detailed review of computed tomography study combined with histopathological studies has shown mixed bony-membranous atresia in about 70% of cases and purely bony atresia in 30% of cases.
