Background and Objectives Frontal recess anatomy can be very complex, with accessory cells extending to the frontal sinus and possibly contributing to the obstruction of the frontal sinus. However, there is still controversy on the effect of the frontal recess cells. We designed this study to assess the effect of frontal recess cells on frontal sinusitis. Subjects and Method We retrospectively reviewed chart and collected data of those who visited the outpatient clinic between January and June, 2011. Parnasal sinus CT was taken with Brillance 64-slice computed tomography scanners. The image was reviewed by two or more otolaryngologists to identify the frontal recess cells. The nasofrontal isthmus diameter and the area of nasofrontal isthmus was reconstructed and measured with workstation. Then, we compared the radiological results of frontal recess cells with the frequency of frontal sinusitis. Results The presence of anterior group of frontal recess cells showed no influence on the frontal recess anatomy. The presence of frontal bullar cell was significantly associated with the development of frontal sinusitis by simple (p=0.001) and multiple (p=0.038) logistic regression models. It was shown that the narrower the area of frontal isthmus the more developed were the frontal sinusitis, showing statistically significance in the simple (p=0.013) and multiple (p= 0.017) logistic regression models. Conclusion Our results also showed that similar results compared to previous Asianreport. The narrowness of nasofrontal isthmus could be the cause of frontal sinusitis. The frontal bullar cell could be the cause of frontal sinusitis encroaching on the frontal recess and affect the nasofrontal pathway.

Background and Objectives:The frontal recess (FR) cells, including the frontal cell (FC), agger nasi cell (ANC), supraorbital ethmoid cell (SOC) and inter-frontal sinus septal cell (IFSSC), can interfere with the drainage system of the frontal sinus. We evaluated the relationship between the FR cells and the frontal sinusitis. Subjects and Methods:All paranasal sinus CT scans performed from July 2004 through June 2005 were reviewed. Of the 675 scans reviewed, 317 patients (634 sides) were selected for data collection. Exclusion criteria included a clinical history of neoplasms, bony deformities, and extensive disease responsible for obscuring the bony anatomy. Similarly, CT scans with severe artifacts were also excluded. Result:FCs were present in 21.9% of the patients. According to the Bent’s classification, the prevalence of each FC type was as follows; type 1 FC (13.6%), type 2 FC (3.2%), type 3 FC (1.9%) and type 4 FC (3.1%). Of the four types of FR cells, type 4 had a significant association with frontal sinusitis. The incidence of hyperpneumatized frontal sinus, ANC, SOC, IFSSC were significantly higher among patients with the FC than those without the FC (p<0.05). Patients without the ANC or with type 1 uncinate process, according to Stammberger’s classification, displayed a higher frequency of frontal sinusitis (p<0.05). There was a statistically significant decrease in the frequency of frontal sinusitis among patients with hypopneumatized frontal sinus (p<0.05). Conclusion:In our series, the frontal sinusitis was influenced by each types of FC, attachment sites of uncinate process and the degree of frontal sinus pneumatization. Therefore, these anatomic variations in the frontal recess should be appropriately addressed during the surgical management of the frontal sinusitis.

비내시경 전두동 수술

김경래,강석영 대한이비인후과학회 2014 대한이비인후과학회지 두경부외과학 Vol.57 No.10

Surgery on the frontal sinus or frontal recess remains a challenge for rhinologist because of its variability and complex anatomy. Its location, relatively complex and narrow frontal recess also make visualization difficult and predispose it to stenosis. Significantly, serious complications are possible due to the anterior ethmoidal artery, orbit and anterior cranial fossa. An understanding of frontal sinus and frontal recess anatomy is essential to perform endoscopic frontal sinus surgery. This paper examines frontal sinus anatomy and then variable procedures of endoscopic frontal sinus surgery. The selection of less invasive procedure as possible after assessment of the patient’s history, diagnostic endoscopy, and the CT scan makes successful endoscopic treatment of frontal sinus diseases.

Background and Objectives:This research aimed to evaluate the prevalence of specific frontal reces cells in Koreans using the classification developed by Lee, et al. Subjects and Method:Frontal recess was studied using high resolution CT scans of normal 60 Koreans. :Thre volunters were found to have sinusitis around frontal recess in CT and therefore were excluded from this study. Agger nasi cells were observed in 107 sides (94.0%), frontal cell type 1 in 26 sides (22.8%), type 2 in 16 sides (14,0%), type 3 in 9 sides (7.9%) and type 4 in 0 side (0.0%). Frontal bullar cells were observed in 16 sides (14.0%), suprabullar cells in 45 sides (39.5%) and supraorbital ethmoid cells in 3 sides (2.6%). Intersinus septal cells were observed in 10 sides (8.8%) and terminal reces in 76 sides (66.7%). Conclusion:This is the first study conducted about the Korean prevalence of frontal reces cells using the new clasification. (Korean J Otolaryngol 2007 ;50 :115-20)

Frontal Fibrosing Alopecia 7예에 대한 고찰

정기헌 ( Ki Heon Jeong ),유박린 ( Bark Lynn Lew ),심우영 ( Woo Young Sim ) 대한피부과학회 2008 大韓皮膚科學會誌 Vol.46 No.4

Background: Frontal fibrosing alopecia (FFA), typically observed in elderly women, is characterized by a band of frontal or frontoparietal hair recession with scarring and a marked decrease, or a complete loss of the eyebrows. Objective: To describe the clinical and histopathological features, and response to treatment of FFA in Korean patients. Methods: A total of 7 female patients, diagnosed as FFA at our department from 2003 through 2006, were evaluated. Results: All patients presented with a band of symmetric recession of the frontoparietal hairline. Four patients (57.1%) had symmetric loss of lateral eyebrows. Two patients (28.6%) were premenopausal. The histologic features were similar in all patients with a reduction of the number of hair follicles, and a perifollicular lymphocytic infiltration with lamellar fibrosis limited to the upper portions of the follicles. The progression of the condition stopped in all patients after topical steroid treatment. Conclusion: Cases of FFA affected in premenopausal female patients drove us to consider that this condition is not exclusive to postmenopausal females. To make a diagnosis of FFA, we should remind ourselves of the typical clinical and pathologic features. Further studies are necessary to confirm the possible role of treatment in FFA and stop the progression in the early stages of FFA. (Korean J Dermatol 2008;46(4):459~464)

Approach to Frontal Sinus Outflow Tract Injury

김용현,김백규 대한두개안면성형외과학회 2017 Archives of Craniofacial Surgery Vol.18 No.1

Frontal sinus outflow tract (FSOT) injury may occur in cases of frontal sinus fractures and nasoethmoid orbital fractures. Since the FSOT is lined with mucosa that is responsible for the path from the frontal sinus to the nasal cavity, an untreated injury may lead to complications such as mucocele formation or chronic frontal sinusitis. Therefore, evaluation of FSOT is of clinical significance, with FSOT being diagnosed mostly by computed tomography or intraoperative dye. Several options are available to surgeons when treating FSOT injury, and they need to be familiar with these options to take the proper treatment measures in order to follow the treatment principle for FSOT, which is a safe sinus, and to reduce complications. This paper aimed to examine the surrounding anatomy, diagnosis, and treatment of FSOT.
