The effect of IDU and cryocautery in the treatment of Herpes Simplex Keratitis was presented. The cryoapplicator was a model of Krwawlcz probe (2 mm in diameter) which was refrigerated in a mixture of dry ice and methyl alcohol. The applicator was appJied on the lesions 7 seconds each and antibiotics and atropine solutions were instilled. A good result was experienced in the treatment of several cases of dendritic kenititis by freezing the corneal lesions by means of cryoappJicator, which had not been responded to IDU therapy speedy. The deep neovascularization of the cornea in a case of stromal keratitis was disappeared after cryocautery for the treatment of the superficial corneal ulcers.

4.Cryoextraction of Cataract.
Journal of the Korean Ophthalmological Society 1973;14(1):52-55
In 1910 Scholler introduced the use of low temperatures in the field of ophthalmology. The report of cryoextraction of cataract by Krwawicz in 1961 acted as a catalyst; ophthalmologist all over the world saw the value of the cryosurgery in reducing the number of unintentional capsular ruptures. There are several types of cryogenic instruments. The most commonly used cryogens in ocular surgery are solid carbon dioxide, halogenated hydrocarbons (Freons) and liquid nitrogen. The major advantage of cryoextraction over the forceps and erisophake technics is the reduction of unintentional breakage of the lens capsule with the resulting decrease in the formation of secondary membranous cataracts and in the onset of postoperative inflammations. The applications of cryoextraction on the intumescent cataract, lens witb torn capsule, luxated lens and planned extracapsular method are briefly described.

The fat embolism syndrome is a complication which encounters rarely after fractures of pelvis and long bones of lower extremity of severe injury of soft tissue, and may results in microinfarctions in lungs, brain, heart, kidneys and other important organs when fat globules flow from bone marrow into small vessels. And that is the one of the main cause of death within 72 hours after major trauma of long bones. Diagnosis of fat embolism syndrome was made by clinical criteria by Gurd, but, majority of cases didn't show characteristic clinical symptoms or signs. Recently CT and MRI of the brain are adopted to the diagnosis of FFS as a new method. Authors experiences six cases of fat embolism syndrome from Mar. 1991 to Mar. 1994 and analyzed the brain MRI findings. We concluded that the brain MRI findings such as diffuse brain swelling, petechial hemorrhage and microinfarctions were helpful to diagnose clinically apparent or subclinical fat embolism syndrome.

ACL plays an important role in stability of knee joint and its injury causes instability of joint which is known as the initiation of problem knee. Reconstruction of the anterior cruciate ligament would be preferred to the primary repair in treatment. And recently with the advance of arthroscopic technique and development of bone-patellar tendon-bone (BPB) graft material, the result of reconstruction is somewhat superior to that of primary repair. Authors compared the results of 20 primary repairs (Group I ) and 20 reconstructions (Group II) among 64 acute ACL injury treated Sung-Ae General Hospital from January 1989 to December 1994. The results were as follows: 1. Most common associated injuries were medial collateral ligament rupture and medial meniscal tear. 2. Group I showed postoperatively 13 negative anterior drawer test, 12 negative Lachmann test and 12 negative pivot shift test and group II showed postoperatively 17 negative anterior drawer test, 15 negative Lachmann test and 17 negative pivot shift test. (p<0.05) 3. In postoperative Lysholm knee scoring scale, group I showed 86 points and group II showed 93 points (p<0.05). 4. In postoperative KT-1000 arthrometer, 12 cases in Group I and 16 cases in Group II showed less than 2mm difference with sound side (p<0.05).

Background:
Orbital medial wall fractures, which are more common than inferior wall fractures, have traditionally been difficult to diagnose with conventional radiography. As the fracture extends deep into the bony orbit, accurately visualizing internal structures becomes challenging, increasing the risk of optic nerve compression. In a previous study, the author introduced a technique for treating medial orbital wall fractures using a combined transethmoidal and transcaruncular approach. In this study, the authors hypothesized that the use of surgical navigation could enhance precision, safety, and anatomical reconstruction in this approach and employed navigation during surgery for medial orbital wall fractures and evaluated whether it improved postoperative functional and anatomical outcomes while minimizing complications.
Methods:
From September 2021 to November 2023, 48 patients with isolated medial wall fractures underwent surgical treatment using a combined transcaruncular approach and transethmoidal packing to repair the orbital fracture. Of these patients, 23 underwent surgery with the use of intraoperative navigation, while the other 25 did not. Intraoperative navigation was employed to facilitate precise fracture reduction and reduce the risk of optic nerve injury. The outcomes were compared by dividing the patients into two groups. Preoperative and postoperative assessments included ophthalmologic evaluations, Hertel exophthalmometry, and computed tomography-based orbital volume measurements.
Results:
The surgical approach with intraoperative navigation was successfully performed in all patients. Postoperative outcomes showed full recovery without residual symptoms or complications. Orbital volume measurements indicated a significant reduction in the preoperative orbital volume ratio from 109.03% to 104.80% postoperatively (p< 0.001). However, changes in the Hertel scale were not statistically significant (p = 0.086).
Conclusion
The integration of intraoperative navigation in medial orbital wall fracture surgery enhances the precision of medial orbital wall restoration and minimizes postoperative complications, supporting its use in the surgical management of medial orbital fractures.
