BACKGROUND: To compare clinical findings of orbital trapdoor fractures between adult and paediatric patients.
METHODS: Paediatric patients were categorised into two groups by age: children (0-9 years) and adolescents (10-19 years). Adult patients were categorised into two groups by age: early (20-44 years) and middle-late adulthood (≥45 years). Demographic data, ocular and periocular complications, CT findings and binocular single vision field (BSVF) were compared among age groups.
RESULTS: This study included 105 patients (105 sides, 22 children, 59 adolescents, 14 patients in early adulthood and 10 patients in middle-late adulthood). In patients with fractures of the orbital floor and medial wall, both walls presented as trapdoor fractures in paediatric patients, while one wall presented as a non-trapdoor fracture in adult patients (p=0.061). None of the adult patients showed extraocular muscle incarceration, whereas this was present in 8 of 22 children (36.4%) and 7 of 59 adolescents (11.9%) (p=0.005). Hypoesthesia of the infraorbital nerve more frequently occurred in adults (p=0.004). As the preoperative BSVF was larger in adult than in paediatric patients (p=0.007), the percentage of adult patients who underwent surgical reduction of orbital fractures tended to be lower (p=0.058). Postoperative change in BSVF was smaller in adult patients (p=0.005).
CONCLUSIONS: Fracture pattern, type of incarcerated tissue and incidence of hypoesthesia of the infraorbital nerve were different between adult and paediatric patients. Adult patients had a larger preoperative BSVF and less need for surgical reduction; however, there was less improvement in postoperative BSVF.
