Frontal sinus models and onlay templates in osteoplastic flap surgery.
Summary of "Frontal sinus models and onlay templates in osteoplastic flap surgery."
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.

Giant paranasal sinus osteomas are rare tumors that may be very closely adherent to surrounding anatomical structures, and complete removal of these tumors may be very challenging. We report 6 cases o...
To compare frontal sinus cranialization to obliteration for future prevention of secondary mucocele formation following open surgery for benign lesions of the frontal sinus.
Chronic frontal sinus disease has always been a difficult problem to treat. We undertook this study to evaluate our results of frontal recess surgery, to determine the factors which affected the surgi...

Medical and Biotech [MESH] Definitions
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.
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.
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.
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.
