Nasal Cavity CT Imaging Contribution to the Diagnosis and Treatment of Choanal Atresia

Choanal atresia: a review of contemporary treatment strategies

PURPOSE OF REVIEW

Choanal atresia (CA) is a congenital nasal airway anomaly that, when present bilaterally, requires urgent surgical intervention. Surgical technique has evolved since its inception with most practices now favoring an endoscopic repair. Restenosis requiring revision surgery is a frequent complication, occurring in as many as 50% of cases. This review aims to highlight the most common surgical approaches, techniques used to prevent restenosis, and newer adjuncts to surgery that may improve outcomes.

RECENT FINDINGS

Bioabsorbable, steroid-eluting stents were first developed for the adult chronic rhinosinusitis population but have been adapted for use in choanal atresia since 2017. The existing literature consists of multiple case series and one case-control study comparing these stents to traditional stents. To date, there have been no reports of restenosis or stent-related complications with these newer products.

SUMMARY

Choanal atresia remains a difficult surgical pathology for which sustainable surgical results can be challenging. There is reason for optimism in bioabsorbable, steroid-eluting stents as an adjunct to CA repair if future studies expound upon their safety and efficacy.

Imaging of Pfeiffer Syndrome: A Case Report

BACKGROUND: Pfeiffer syndrome (PS) is a rare case in the Asian population, and only a few have been reported in Indonesia. This case report aims to spotlight the identification of PS with its correlated radiological imaging and distinguish it from other syndromes. CASE REPORTS: The authors report a case of a 5-year-old girl with PS, manifested by brachyturricephally, broad thumbs and big toes, and medially deviated big toes. The patient also had proptosis, midface hypoplasia, and bilateral Syndactyly of the fingers and toes. This report confirms the thorough examination procedures and indexes to identify PS as a literature reference for the research of reported PS in Southeast Asian race patients and as one comprehensive source for identification using index figures. CONCLUSION: This report provides a detailed radiology interpretation of PS on Southeast Asian race patients. Radiological findings can help in diagnosing and determining adequate treatment as needed.

[The efficacy of endoscopic plasty for children with bilateral congenital choanal atresia]

Objective:To evaluate the clinical effect of endoscopic repair for the treatment of children with bilateral congenital choanal atresia. Methods:A retrospective analysis was conducted in our department that six children who were diagnosed as bilateral congenital choanal atresia by nasopharyngeal endoscopy and nasal CT scanning. All cases underwent endoscopic repair and placed the silicone stent to support the enlarged nostrils for six months, and these patients were followed up to observe re-atresia rate after taking out of the supporting tube. Results:Six cases' nasal ventilation were effectively improved after operation without serious complications, 5 cases showed a satisfactory curative effect after taking out of the supporting tube, only 1 case with bony atresia found choanal re-atresia during follow-up. Conclusion:The clinical effect of using endoscopic repair for children with bilateral congenital choanal atresia showed remarkable efficacy with a low re-atresia.
