BACKGROUND Fronto-orbital advancement for nonsyndromic craniosynostosis has been thought to injure frontal sinus buds, lead to chronic sinus disease, and influence final forehead shape. This study investigates the effect of fronto-orbital advancement in infancy on subsequent frontal sinus volume, morphology, and disease. METHODS The authors conducted a retrospective review of nonsyndromic craniosynostosis patients treated with fronto-orbital advancement in infancy with a head computed tomographic scan obtained at age 7 to 18 years. Facial trauma patients served as age-matched controls. Frontal sinus characteristics were determined using three-dimensional reconstructions. RESULTS The study included 33 nonsyndromic craniosynostosis patients who underwent fronto-orbital advancement (n = 20 unicoronal; n = 13 metopic) and 20 control patients. The incidence of at least unilateral pneumatization was 94 percent for fronto-orbital advancement subjects and 95 percent for control subjects. Mean frontal sinus volumes for unicoronal synostosis, metopic synostosis, and control groups were 3427 ± 2294, 4576 ± 3510, and 4157 ± 3963 mm, respectively (p = 0.598). Asymmetry scores were as follows: unicoronal synostosis, 56 ± 35 percent; metopic synostosis, 36 ± 33 percent; and control, 23 ± 24 percent (p = 0.010). Unicoronal subjects displayed prominent asymmetry, with increased pneumatization on the unaffected side. Frontal sinus volume correlated with age at computed tomography but not with age at fronto-orbital advancement. Interrater reliability was 0.997. One fronto-orbital advancement subject and zero control subjects demonstrated computed tomographic evidence of frontal sinus disease. CONCLUSIONS Frontal sinus volume, morphology, and disease do not differ significantly between control subjects and nonsyndromic craniosynostosis subjects following fronto-orbital advancement, but subtle differences such as increased asymmetry in the unicoronal synostosis group can be appreciated. Further research with syndromic craniosynostosis patients undergoing multiple procedures may help elucidate the association between surgical disruption and frontal sinus development.

Concurrent repair of orbital shallowness with craniosynostosis surgery: two late cases of simultaneous orbital decompression.

Early closure of cranial sutures results in various types of cranial vault deformities, named craniosynostosis. Although mostly associated with syndromic cases, bony orbit deformities such as exorbitism can be seen with various types of craniosynostosis. This condition can be associated with papilledema and besides its effect on the patient's appearance can cause subluxation of the globe, lagop...

Frontal mucocele with an accompanying orbital abscess mimicking a fronto-orbital mucocele: case report

BACKGROUND Mucoceles are slowly expanding cystic lesions with respiratory epithelium containing mucus most commonly affecting the frontal and ethmoidal sinuses. They are caused by obstruction of sinus ostium. Mucoceles exert pressure on the bony boundaries and due to the proximity to the brain and orbit extension to these areas are common. CASE PRESENTATION A case of a frontal mucocele with a...
