Disease relevance of Frontal Sinus

• OBJECTIVE: To evaluate the efficacy hydroxyapatite cement as an alternative to autologous fat in the obliteration of the frontal sinus after trauma or chronic suppuration [1].
• Cholesterol granuloma of the frontal sinus [2].
• Endoscopically guided frontal sinus beclomethasone instillation for refractory frontal sinus/recess mucosal edema and polyposis [3].
• Eleven osteomas (32%) were removed using an osteoplastic frontal sinus approach with coronal incision [4].
• Symptomatic epilepsy due to a huge frontal sinus mucocele. A case report [5].

High impact information on Frontal Sinus

• Finally, in the midline the frontal sinus never reached more than 4 cm above the nasion [6].
• In vivo model for frontal sinus and calvarial bone defect obliteration with bioactive glass S53P4 and hydroxyapatite [7].
• Based upon these osteogenic qualities, the ease of shaping the composite, and the lack of infection in the frontal sinus region, it is concluded that this substance could be a valuable new material for human cranioplasty [8].
• BACKGROUND: Frontal recess anatomy can be very complex, with accessory cells such as frontal, agger nasi, and intersinus septal cells encroaching on the frontal recess and possibly contributing to obstruction of the frontal sinus [9].
• BACKGROUND: Classic approaches to frontal sinus fracture involve bicoronal or direct forehead incisions [10].

Chemical compound and disease context of Frontal Sinus

• Use of titanium mesh in comminuted fractures of frontal sinus anterior wall [11].
• In order to minimize steroid complications while increasing the locally absorbed dose, beclomethasone (approximately 1 cc, 84 mcg/100 microliters) was instilled under endoscopic guidance directly into the frontal sinus in 31 instances in 16 patients with postoperative frontal recess/sinus polyposis and mucosal edema [3].
• Removal of a frontal sinus osteoma using the CO2 laser [12].
• The intraoperative finding was a brain prolapse both into the frontal sinus and into the ethmoidal cavity with a large dura-bone defect at the site of the former fracture line, which was closed with refobacin-bone-meal fibrin sealant plasty and glued periostal patch [13].

Biological context of Frontal Sinus

• Dense particles of hydroxyapatite (HAP) were consolidated in the frontal sinus of dogs, and bone formation with time was observed in undecalcified ground sections using Cole's HE stain [14].
• Sinus roentgenograms and technetium Tc 99m medronate bone scanning further support the use of plaster of Paris as an alloplast and assess its osteoneogenic capacity when implanted in the frontal sinus of dogs; complete bone regeneration was demonstrated in six dogs within four to six months [15].

Anatomical context of Frontal Sinus

• CONCLUSION: Hydroxyapatite bone cement seems to be a simple and effective method for frontal sinus obliteration and prevention of cerebrospinal fluid leakage [16].
• The steroid effect on polypoid masses was heterogeneous in different anatomic areas (maxillary sinus 40%, anterior ethmoid 19%, posterior ethmoid 33%, sphenoidal sinus 61%, frontal sinus 46%) [17].
• Coronal computerized tomography and instillation of contrast medium through the catheter showed communication between epidural space and left frontal sinus [18].
• Six patients (group A) were treated using autogenous abdominal fat for obliteration purposes, while the other 6 patients (group B) underwent frontal sinus obliteration using a hydroxyapatite cement [19].

Associations of Frontal Sinus with chemical compounds

• METHODS: Fourteen patients with severely comminuted frontal sinus fractures were treated with titanium mesh from 1994 to 1999 [20].
• Collision tumor of the frontal sinus: evidence of prior intrasinus instillation of thorotrast [21].
• RESULTS: Clotrimazole solution (1%) was infused during a 1-hour period via catheters surgically placed in the frontal sinus and nose (27 dogs) and via nonsurgically placed catheters in the nose (18) [22].
• The highest risk of implant infection comes from reconstruction in the area of the frontal sinus, immediately beneath coronal incisions, and in patients who receive postoperative radiation treatment [23].
• Plaster of paris as an alloplastic implant in the frontal sinus [15].

Gene context of Frontal Sinus

• We reported the superior attachment sites of the uncinate process, the diameter of the frontal sinus ostium, and prevalence of the agger nasi cells [24].
• Development of the frontal sinus and glabellar morphology after frontocranial remodeling for craniosynostosis in infancy [25].
• Finally, comminuted, displaced anterior and posterior table fractures, especially those with persistent CSF leakage and associated nasofrontal duct involvement, are best handled with frontal sinus cranialization [26].
• CONCLUSION: Image-guided OFS results in a confident and accurate entry into the frontal sinus [27].
• Chordoma of the frontal sinus [28].

Analytical, diagnostic and therapeutic context of Frontal Sinus

• OBJECTIVE: To test the efficacy of a simple technique of frontal sinus obliteration during low frontal craniotomy using hydroxyapatite cement instead of more traditional methods, such as pericranial flaps, free muscle or adipose grafts, lumbar drainage, or fibrin glue [16].
• INTERVENTION: After a subtotal Le Fort II osteotomy, tension wires were fixed to the zygomatic buttresses and frontal sinus walls by way of titanium miniplates and mesh and connected to a rigid external distractor [29].
