Objective:Precise delineation of the extent of frontal sinus pneumatisation is a crucial step in osteoplastic flap frontal sinus surgery. The authors present a novel method of achieving this objective.Methods:First, models of the frontal area are generated using three-dimensional printing based on pre-operative computed tomography image data. These models are then used to create an onlay template of the frontal sinus, which is used intra-operatively.Results:In a series of 10 patients undergoing osteoplastic flap frontal sinus surgery, the described frontal sinus templates were consistently accurate to within 1 mm.Conclusion:Frontal sinus templates are potentially useful adjuncts to current techniques employed to guide frontal sinus surgery.

Chronic frontal sinus infections in the setting of previous trauma or tumor removal are challenging clinical scenarios. To remove and débride all chronically infected tissue, obliterate dead space, a...
The problem of postoperative management after frontal sinus surgery remains a challenge. The bilateral opening created in the Draf III procedure does not fit any currently available stent, and patient...
The frontal sinus is considered the most challenging sinus to address surgically. There are no current classifications of the degree of surgical complexity of different frontal sinus configurations. T...
Research on frontal sinus cells has been conflicting regarding relationship between frontal sinus cells and frontal sinus disease. There are no published studies regarding gender differences in fronta...
Despite common goals of frontal sinus fracture treatment (restoring forehead contour and creating a safe sinus), there remains significant variability in evaluation and treatment.
The purpose of this study is to compare how two different post-surgical treatments that both deliver steroids to the frontal sinus opening affect your healing after frontal sinus surgery.
The objective of the PROGRESS Study is to assess the safety and efficacy of the Propel Mini steroid-eluting Sinus Implant when placed in the frontal sinus opening following frontal sinus s...
Comparison of limited excision-primary closure, Limberg, and modified Limberg flap techniques for the surgical treatment of pilonidal sinus disease, each performed by a separate surgeon, i...
The investigators think, that the treatment of Sinus pilonidalis with excision and covering of the defect with a Limberg-flap is a very good treatment option. The investigators are introdu...
Background. Limberg flap, one of the recently being popularized off-midline closure techniques, is widely performed for the treatment of sacrococcygeal pilonidal sinus; however, recurrence...
Air-filled spaces located within the bones around the NASAL CAVITY. They are extensions of the nasal cavity and lined by the ciliated NASAL MUCOSA. Each sinus is named for the cranial bone in which it is located, such as the ETHMOID SINUS; the FRONTAL SINUS; the MAXILLARY SINUS; and the SPHENOID SINUS.
One of the paired, but seldom symmetrical, air spaces located between the inner and outer compact layers of the FRONTAL BONE in the forehead.
Inflammation of the NASAL MUCOSA in the FRONTAL SINUS. In many cases, it is caused by an infection of the bacteria STREPTOCOCCUS PNEUMONIAE or HAEMOPHILUS INFLUENZAE.
Endonucleases that remove 5' DNA sequences from a DNA structure called a DNA flap. The DNA flap structure occurs in double-stranded DNA containing a single-stranded break where the 5' portion of the downstream strand is too long and overlaps the 3' end of the upstream strand. Flap endonucleases cleave the downstream strand of the overlap flap structure precisely after the first base-paired nucleotide, creating a ligatable nick.
A surgical procedure to correct MYOPIA by CORNEAL STROMA subtraction. It involves the use of a microkeratome to make a lamellar dissection of the CORNEA creating a flap with intact CORNEAL EPITHELIUM. After the flap is lifted, the underlying midstroma is reshaped with an EXCIMER LASER and the flap is returned to its original position.
