HUBUNGAN ANTARA KEDALAMAN SINUS FRONTALIS DAN MATURASI TULANG TANGAN

CORRELATION BETWEEN FRONTAL SINUS DEPTH AND HAND WRIST MATURITY

Abstract

The appropriate planning of orthodontic therapy with regard to appliance selection, information on the patient’s stage of
somatic maturity is needed. Hand wrist maturity has been shown to be closely related with the pubertal growth spurt;
therefore hand wrist radiographs have been recommended for indirect assesment of somatic maturity. However, the
routine use of hand wrist radiographs has lately been questioned from the radiation-hygiene, safety point of view. In a
recent cephalometric investigation, it was found that the frontal sinus development showed a growth rhythm similar to the
body height development. Furthermore, it has been proposed that frontal sinus enlargement follows general bone growth
but little evidence has been shown. The objective of this study was to investigate the correlation between frontal sinus
depth and hand wrist maturity in Deuteromalayid group aged 7 to 17 years. A cross sectional study was conducted in 138
subjects (69 males, 69 females). The frontal sinus depth and hand wrist maturation was determined using Ertürk’s and
Fishman’s method, respectively. The result of this study showed that there was a moderate correlation between frontal
sinus depth and hand wrist maturity in males (r = 0.608) and females (r = 0.647). From this study, it can be concluded
that the usage of frontal sinus depth to substitute hand wrist maturity to assess the skeletal maturity is not appropriate
enough.
