ANATOMICAL RATIONALE FOR CHOOSING A BLADE FOR POWER-ASSISTED ADENOIDECTOMY IN CHILDREN DEPENDING ON DENTITION.

OBJECTIVE

The aim: To study the anatomic features of the facial skull structures in children of various ages depending on dentition.

PATIENTS AND

METHODS

Materials and methods: One hundred and forty-four children aged 2-12 years were divided into 4 groups depending on dentition. They underwent anthropometric measure¬ments during adenoidectomy. Based on the cosine theorem, the calculated values were obtained.

RESULTS

Results

The distance from choana to the free edge of the retracted soft palate gradually increases from 2.01±0.61 cm in children with stable primary dentition up to 3.09±1.02 cm with mixed dentition. Palato-nasopharyngeal angle in children with stable primary dentition is 126.25±8.76°, in children with aging primary dentition - 132.81±12.21°, and in children with mixed dentition - 120.54±13.72°.

CONCLUSION

Conclusions

The optimal configuration of the blade for power-assisted adenoidectomy in children with stable primary dentition has an angle of 53.53±8.76°, and the length of the working part of 2.01±0.61 cm, in children with aging primary dentition - 47.18±12.21° and 2.10±0.71 cm, with mixed dentition - 59.45±13.72° and 3.09±1.02 cm, respectively.
