The presence of frontal sinuses following bilateral fronto-orbital advancement is discussed controversially in the literature. In a retrospective study, 33 patients (18 male and 15 female) were operated on between 1982 and 1993, with at least one year postoperative follow-up and with a minimum age of 6 years at the end of the follow-up period following bilateral fronto-orbital remodelling, were included. The average age at which the procedure was performed was 29 months with a minimum of 3 months and a maximum of 7.8 years. The study presented shows a pneumatization of the frontal sinus in 72.7% of 33 patients following bilateral fronto-orbital advancement. The first radiographic signs of sinus development were detected between the ages of 4 and 11, average 8.3 years. There were no statistically proven correlations between frontal sinus pneumatization and age at operation or the amount of advancement or sex of the patients. Surgical enlargement of the cranium by frontal advancement with adequate stabilization results in an enlargement of the neurocranium, thereby decreasing pressure on the inner frontal cortex and allowing frontal sinus pneumatization to proceed normally. Hence, the development of a frontal sinus may be a reflection of the effectiveness of the surgical therapy.
双侧额眶前移术后额窦的出现情况在文献中存在争议。在一项回顾性研究中，纳入了1982年至1993年间接受手术的33例患者（18例男性和15例女性），这些患者在双侧额眶重塑术后至少有1年的术后随访，随访期结束时最小年龄为6岁。手术时的平均年龄为29个月，最小为3个月，最大为7.8岁。该研究显示，33例患者中有72.7%在双侧额眶前移术后出现额窦气化。鼻窦发育的首个影像学征象在4至11岁之间被检测到，平均为8.3岁。额窦气化与手术年龄、前移量或患者性别之间没有经统计学证实的相关性。通过额部前移进行颅骨手术扩大并给予充分固定，会导致脑颅扩大，从而减轻额叶内皮质的压力，使额窦气化正常进行。因此，额窦的发育可能反映了手术治疗的效果。
