Early surgical intervention for choanal atresia in infants is crucial. The transpalatine approach effectively restores nasal patency, improving nutrition and reducing respiratory infections.
Area of Science:
- Otolaryngology
- Pediatric Surgery
- Congenital Abnormalities
Background:
- Choanal atresia is a congenital condition affecting nasal airway patency in infants.
- Bilateral choanal atresia presents a critical emergency, necessitating prompt diagnosis and management.
- Associated anomalies occur in a significant proportion of affected infants.
Purpose of the Study:
- To evaluate the efficacy and outcomes of surgical management for choanal atresia in a pediatric cohort.
- To assess the long-term effects of the transpalatine surgical approach on craniofacial development and palatal function.
- To identify factors contributing to surgical success and failure in treating choanal atresia.
Main Methods:
- Retrospective review of 65 infants diagnosed with choanal atresia over a 19-year period.
- Surgical correction primarily performed using a transpalatine approach under general anesthesia within the first six months of life.
- Data collection included patient demographics, type of atresia, associated anomalies, surgical technique, and outcomes.
Main Results:
- A total of 65 infants were treated, with 30 cases of bilateral and 35 of unilateral choanal atresia.
- The majority of patients (50) were female, and 27 cases involved other congenital anomalies.
- Early surgical treatment via the transpalatine route demonstrated success in restoring nasal patency and improving feeding and respiratory status.
Conclusions:
- Early surgical intervention for choanal atresia is the preferred management strategy.
- The transpalatine approach is effective, allowing direct surgical visualization without compromising palatal growth or function.
- Challenges in maintaining the newly created airway are the primary cause of surgical failures.
Abstract:
During a period of 19 years we have treated 65 infants with choanal atresia. Thirty of them showed a bilateral atresia, thirty-five a unilateral (29 left-sided, 6 right-sided). Fifty patients were girls, fifteen boys. In 27 cases the abnormality was combined with other anomalies. Most infants have been operated upon in the first six months of their life by a transpalatinal approach in general anethesia. From the results the following conclusions can be made: early treatment is the method of choice; restoration of nasal permeability, although minimal, allows normal nutrition and diminishes a number of respiratory infections, due to choking. The transpalatinal approach permits a direct control of the surgical area. It does not inhibit the growth of the hard palate and the function of the soft palate. Failures are caused by difficulties to keep the new passage open.
