The radiological and surgical anatomy of the frontal sinus should be well-known in all age groups to successfully manage frontal sinus diseases and reduce the risk of complications in sinus surgery....
To define frontal sinus and frontal cells according to the International Frontal Sinus Anatomy Classification (IFAC) criteria in pediatrics and adults....
A total of 320 frontal recess regions of 160 individuals (80 pediatric, 80 adults) who underwent a computed tomography (CT) scan of the paranasal sinus (PNS) were included in the study. Agger nasi cel...
The incidence rates of the investigated cells were determined to be 93.1%, 41.9%, 60.0%, 76.3%, 58.5%, 18.8%, and 0% in the pediatric group, respectively, and 86.3%, 35.0%, 44.4%, 54.4%, 46.9%, 19.4%,...
Our study results show that IFAC can be used as a guide to increase the chance of surgical treatment in the pediatric and adult groups and that the prevalence of frontal cells can be determined radiol...
To compare two types of CT acquisition parameters: CT scan of the facial bone and CT scan of the sinuses, for studying the ethmoidal slit and its relationship with the frontal sinus and anterior ethmo...
Retrospective study of 145 scans of the sinuses and 79 of the facial bones performed between 2012 and 2016. On each scan, the visibility of the ethmoidal slits, their length, their distance from the e...
The ethmoidal slit was better visualized on CT scans of the facial bone (58.2%) than on those of the sinuses (43.1%) (p = 0.02). The distance between the anterior ethmoidal artery and the anterior par...
CT scans of the facial bone are better than CT scans of the sinuses for identifying ethmoidal slits and their distance from the canal of the anterior ethmoidal artery. The identification of these elem...
Despite the impressive evolutions in endoscopic endonasal approaches and instrumentations, the frontal sinus remains a challenging area. Different surgical options have been described over the years, ...
Frontal sinus surgery includes minimally invasive endonasal approaches (balloon dilatation, Draf type I); extended endonasal approaches (Draf type IIA-IIB-IIC, Draf type III and their modifications vi...
Recent advances in endoscopic endonasal techniques have deeply reshaped the surgical options to manage frontal sinus diseases, in an attempt to minimize the invasiveness of the procedures and maximize...
(1) Background: Among the four paranasal sinuses, the frontal sinus is in the frontal bone. Recent research trends have been focusing on identifying sex based on the frontal sinus. Thus, this study ai...
To explore the effects of Draf1-3 on frontal sinus airflow and frontal sinus irrigation in people with different frontal sinus development METHODS: The development of the frontal sinus and the distrib...
The moderately developed type of the frontal sinus was the most common. The airflow patterns in the frontal sinus and frontal recess in the moderate development group were laminar, while several large...
Draf1-3 has different effects on the airflow field of the frontal sinus with different developmental types; and Draf1-3 can significantly improve the postoperative flushing of the frontal sinus....
Anterior skull base lesions could be reached by different approaches (subfrontal, pterional, interhemispheric, etc.). In selected cases, the frontal trans-sinusal approach is an effective alternative ...
We present our technique to perform a frontal trans-sinusal approach in a patient affected by a large olfactory groove meningioma....
The frontal trans-sinusal approach allows to approach safely lesions of the median anterior cranial fossa. This approach provides lower brain retraction, easier access to olfactory grooves, and earlie...
Mucoceles of the paranasal sinuses are benign, expansile lesions that develop secondary to sinus ostia obstruction. Presenting signs and symptoms vary widely but frequently include frontal headache an...
Due to the complexity and variety of the frontal recess and sinus anatomy, traditional Draf 2a frontal sinus surgery is challenging. The thickness of the nasofrontal beak and anterior-posterior dimens...
Consecutive adult patients in whom Carolyn's window technique was applied for frontal sinus dissection as part of the endoscopic management of both inflammatory and neoplastic disease were assessed. T...
Forty-five patients (49.1 ± 17.9 years, 48.9% Female) were assessed. All patients had successful frontal sinus patency (100% [95CI: 92.1%-100%]). Morbidities were adhesion (4.8%), crusting (2.4%), pai...
Carolyn's window approach to frontal sinusotomy is a technique that evolves from previously described approaches. Successful frontal sinus patency with very low morbidities is achieved while still wor...
Osteomyelitis of the frontal bone is a rare but devastating complication of frontal sinusitis. Treatment involves aggressive surgery to remove all sequestra in combination with long-term antibiotic th...
To the best of the authors' knowledge, the two cases discussed here represent the first use of tobramycin antibiotic beads in frontal sinus osteomyelitis secondary to chronic rhinosinusitis....
These cases show promising use of tobramycin beads in recalcitrant frontal osteomyelitis....
Historically, early surgical management of frontal sinus outflow tract (FSOT) fractures has been standard practice. There has been a paradigm shift toward nonsurgical or delayed management. Unfortunat...
A retrospective cohort study of FSOT injuries between 2005 and 2019....
Academic, tertiary care medical center....
Radiographic fracture patterns of the frontal ostia (FO) and frontal recess (FR) were recorded as either patent, disrupted, or obstructed. Sinus reaeration, surgical rescue, and complication rates wer...
One hundred patients were identified and 44 met the criteria (88 sinuses). Among nonobstructed FSOT injuries (ie, patent or disrupted), reaeration occurred in 91% of the FO and 98% of FR injuries. Two...
Among nonobstructive injuries to the FSOT, average reaeration rates in observed patients were high (91%-98%). Rescue surgery (2%) and complication rates (2%) were low, suggesting that nonsurgical mana...
