2001 Apr 111(4 Pt 1):603-8.Surgicalanatomy of the nasofrontalduct: anatomical and computedtomographicanalysis.Kim KS, Kim HU, Chung IH, Lee JG, Park IY, Yoon JHAbstractOBJECTIVES:Although complete anatomicalknowledge of the nasofrontalducthasbeen of greatimportance, littleisknownaboutit. We know that it is large enough to maintain drainage function during the acute phase of trauma.There is no true tubular connection between the frontal sinus and the nose exists it is most often a relatively large opening, directly into the frontal recess of the nose or anterior ethmoid.the frontal recess may take the appearance of a duct when narrowed by theethmoid bulla or a pneumatized agger nasi cell.Laryngoscope. Also we note of the SINUS DRAINAGE or the the Nasofrontal duct which is not a correct term.The olfactory bulbs are & tracts are in close contact to the cribriform plate, & the dura is tightly adherent to the to bone in the olfactory groove.Underlying the cribriform plate is the olfactory mucosa of the upper nasal cavity.The overlying frontal bar is the cornerstone of the forehead & anterior skull base. The frontal bar is the thickened bone that bridges the zygomaticofrontal sutures to form the superior horizontal or also known as the TRANSVERSALBUTTRESS.It is thickened & gives structure to the supraciliary & glabellar areas. The frontal sinus provides the convex contour of the frontal bar.Frontal sinus fracture treatment strategies lack statistical power so studies need to have a statistically valid treatment protocols for frontal sinus fracture based on injury pattern, nasofrontal outflow tract injury, and complication(s).This lecture will go thru the anatomy, the apporaches, special things to consider during the sugical repair & a review of complications.Severe infectious complications following frontal sinus fracture: the impact of operativeĭelay and perioperative antibiotic use. Provides little benefit in preventing serious infections.īellamy JL, eta l. Requiring operative intervention is associated with an increased risk forĬontinued antibiotic prophylaxis beyond the perioperative period Relative risk estimates were obtained using multivariable regression.Īntibiotic use beyond 48 hours postoperatively was not associatedĭelay in operative management of frontal sinus fractures in patients Lauder A, Jalisi S, Spiegel J, Stram J, Devaiah AAntibiotic prophylaxis in the management ofĬomplex midface and frontal sinus trauma. May be warranted in cases of severe facial trauma with Postoperative infections however, such antibiotic use Perioperative timeframe does not reduce the rate of The use of additional antibiotics outside the Frontal Sinus Fractures are CONTAMINATED.Special considerations influencing ORIF.
