It is important to choose which approaches should be used to correct the fracture if the operation is indication for surgery in patients with orbital floor fracture. Transorbital, transantral, and endonasal approaches are methods for correcting the orbital floor fracture. The approach needs to be considered the location of the fracture, the degree, the severity of the fracture, the least remaining patient's disability, and preference of the surgeon. We report a case of orbital floor fracture using transorbital approach and endonasal catheter ballooning to resolve the limitations of transorbital approach alone.

Schwannomas are benign tumors arising from the nerve sheaths of peripheral, autonomic and cranial nerves. Between 25% and 45% of all schwannomas occur in the head and neck region but only 4% involve the nasal cavity and paranasal sinus. Moreover, schwannoma of the pterygopalatine fossa is extremely rare. We present a case of schwannoma of the pterygopalatine fossa in a 43-year-old woman. The patient was surgically managed with endoscopic transnasal approach combined with transantral approach. After 16 months, the patient shows no evidence of recurrence.

Most orbital surgeons believe that it's difficult to restore the primary orbital wall to its previous position and that the orbital wall is so thin that cannot be firmly its primary position. Therefore, orbital wall fractures generally have been reconstructed by replacing the bony defect with a synthetic implant. Although synthetic implants have sufficient strength to maintain their shape and position in the orbital cavity, replacement surgery has some drawbacks due to the residual permanent implants. In previous studies, the author has reported an orbital wall restoring technique in which the primary orbital wall fragment was restored to its prior position through a combination of the transorbital and transantral approaches. Simple straight and curved elevators were introduced transnasally to restore the orbital wall and to maintain temporary extraorbital support in the maxillary and ethmoid sinus. A transconjunctival approach provided sufficient space for implant insertion, while the transnasal approach enabled restoration of the herniated soft tissue back into the orbit. Fracture defect was reduced by restoring the primary orbital wall fragment to its primary position, making it possible to use relatively small size implant, furthermore, extraorbital support from both sinuses decreased the incidence of implant displacement. The author could recreate a natural shape of the orbit with the patient's own orbital bone fragments with this dual approach and effectively restored the orbital volume and shape. This procedure has the advantages for retrieving the orbital contents and restoring the primary orbital wall to its prior position.

Purpose: Many surgical methods for reconstruction of orbital floor fracture have been reported, which include subciliary approach, transconjunctival approach, transantral and transnasal endoscopic approach, etc. The purpose of this study is to demonstrate a surgical technique and analyze the results of transnasal endoscopic approach with Foley catheter ballooning without implantation of artificial surgical material through subciliary approach. Methods: Between February 2007 and November 2010, 29 orbital floor fracture patients, who had no herniated muscles through bone fragments, were treated through transnasal endoscopic approach with Foley catheter ballooning. Under the endoscopic view, the operator identified the opening of maxillary sinus. After widening of the opening using forceps, the operator reduced the fragmented bone with curved suction tip. Thereafter, 18-Fr Foley catheter was inserted. Four weeks after the operation, the catheter was removed. Results: Preoperatively, 6 patients had diplopias, 4 patients had limitations of extraocular motions and 3 patients had enophthalmos. After removal of the Foley catheter 4 weeks after the operation, 2 patients had diplopias, 1 patient had a limitation of extraocular motion, 1 patient has an enophthalmos and 1 patient had numbness on the cheek. These symptoms were resolved about 6 months after the surgery. Conclusion: The operative technique of Foley catheter ballooning through transnasal endoscopic approach without implantation of the artificial surgical material through subciliary approach can be considered one of the appropriate techniques for orbital floor fracture.

Purpose: Blow-out fractures are reduced through transcutaneous or transconjunctival incisions. But the field of orbital surgery is difficult due to lack of visualization of fracture site, blind dissection of orbital floor, susceptibility of injury of orbital structures. In these situations, the former technique of using an antral balloon catheter has advantages over other methods for reconstruction because of its rapidity, simplicity, and inexpensiveness. Furthermore, the antral balloon catheter allows not only elevation of the orbital bone fragment but also expansion of the maxillary sinus in cases where there is a fracture of its walls. But postoperative follow-up method using computed tomography is expensive. Hence, we report a simple and inexpensive follow-up method using radiopaque dye inflation. Methods: We performed endoscopic transantral approach in 5 cases of blow-out fracture under general anesthesia. To accomplish this technique, a rigid 4 mm, 0 or 30 degree angled endoscopy was inserted into the maxillary sinus. Inflation of the catheter started gradually, with 10 to 15 mL of saline mixed radiopaque dye (saline: dye, 5 : 1) by syringe and while observing the elevation of the fracture site with endoscope until a proper contour was reached. For the maintain of the position of fractured site, 12 French urinary balloon foley catheter were used in fracture site for 7 - 10 days. Results: Postoperative assessment was performed by means of clinical and simple radiographic examination to secure the catheter under the inferior orbital wall and in the maxillary sinus. No specific complications occurred related to this procedure. Results of the surgery and follow-up in all cases were satisfactory. Conclusion: It may be a better alternative to the conventional follow-up method, with less cost and effectiveness of the catheter patency. The advantages of using the urinary balloon foley catheter with the radiopaque dye include the following : it is safe, efficacy, simple, and especially low cost. On drawback of this method is the discomfort to the patient caused by the catheter during the treatment.

Choanal atresia, described first by Johann Roedere (1755) is an obstruction between the nasal cavity and nasopharyngeal vault, and the diagnosis and treatment were developed because of severity of the disease. Embryologically, incomplete development of olfactory pit, or failure of nasobuccal membrane to rupture, or persistent remaining of buccopharyngeal membrane, etc, all forms the congenital choanal atresia. And the acquired type was the result from syphilis or diphtheria with a resultant stenosing cicatrix and after the inexpert surgery and the trauma. Multiple abnormalities may be present particularly affecting the head, the heart and the alimentary system in the congenital type. The operative technique employed would depend upon the type of obstruction(whether membranous or bony), the age of the patient, and the presence or absence of any associated pathologic condition. Since Emmert (1853) first tried blind puncture of the atretic plate with the trocar, other surgical techniques have been introduced over the years for the correction of choanal atresia, which were the transnasal, transpalatal, transantral and the transseptal approach. Among them, transpalatal approach was proved to be a popular technique, that it provides a direct route, thus permitting an exact reconstruction and low restenosis rate. Recently, we have experienced two cases of choanal atresia and treated successfully with transpalatal approach, so authors report these cases with a review of the literature.
