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

Abstract

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