Rapid developmental changes of the peripheral auditory system in normal infants occur in the first year of life. Specifically, the postnatal development of the external and middle ear affects all measures of external and middle ear function including wideband acoustic immittance(WAI). This article provides an overview of WAI studies in newborns and infants from a developmental perspective. Normative WAI data in newborns are fairly consistent across studies. However, there are discrepancies in some WAI measures between studies, possibly due to differences in sampling, methodology, and instrumentation. Accuracy of WAI measurements is compromised when a good probe seal cannot be maintained during testing or an inaccurate estimate of the cross-sectional area of the ear canal of newborns occurs. Comparison of WAI data between age groups from 0 to 12 months reveals maturation effects. Additional age-specific longitudinal and cross-sectional normative WAI data for infants from birth to 12 months are required to validate and consolidate existing data.

Objective: To analyze the effectiveness of three internal fixation methods, namely hollow screw combined with Kirschner wire tension band, hollow screw combined with anchor nail, and modified 1/3 tubular steel plate, in the treatment of avulsion fracture of tibial tubercle (AFTT) in adolescents.
Methods: Between January 2018 and September 2023, 19 adolescent AFTT patients who met the selection criteria were admitted. According to different internal fixation methods, patients were divided into group A (8 cases, hollow screw combined with Kirschner wire tension band), group B (6 cases, hollow screw combined with anchor nail), and group C (5 cases, modified 1/3 tubular steel plate).

Objective: To discuss the elbow skin fold extension line in Kirschner wire internal fixation of extended supracondylar humeral fractures in children.
Methods: The clinical data of 58 children with extended supracondylar fractures of the humerus who met the selection criteria between August 2021 and July 2024 were retrospectively analyzed. In 28 cases, needle placement of medial epicondyle of humerus was performed with the assistance of the elbow skin fold extension line (study group), and 30 cases were assisted by routine touch of the medial epicondyle of the humerus (control group).

Objective: To compare the effectiveness of ultrasound-guided closed reduction with Kirschner wire fixation and open reduction with Kirschner wire fixation in the treatment of humeral lateral condyle fracture (HLCF) in children.
Methods: A clinical data of 53 children with HLCF admitted between May 2020 and April 2023 and met selective criteria was retrospectively analyzed. Of these, 25 cases were managed with closed reduction and Kirschner wire fixation under ultrasound guidance (closed group), while 28 cases underwent open reduction and Kirschner wire fixation (open group).

Objective: To investigate the effectivess of arthroscopic Wafer surgery combined with triangular fibrocartilage complex (TFCC) insertion point reconstruction in the treatment of Palmer type ⅡC combined with typeⅠB ulnar impingement syndrome.
Methods: The clinical data of 14 patients with Parlmer type ⅡC combined with type ⅠB ulnar impingement syndrome who met the selection criteria between July 2021 and April 2024 were retrospectively analyzed. There were 7 males and 7 females with an average age of 43 years ranging from 16 to 59 years.
