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.

Pigmented lesions of palmar and plantar skin may cause diagnostic problems, because some features of benign lesions in these sites may raise the suspicion of melanoma if considered alone. Transepidermal elimlnation is a mechanism by which a substance is eliminated through the epidermis, and it is apt to be confused with a feature of melanoma that tumor cells are located at all layers of the epidermis. We report a case of transepidermal elimination of nevus cells in acral letiginous nevus which needs a differential dignosis of melanoma.

Protrusion of coil loop(s) and subsequent occlusion of the parent artery is one of the dreadful complications during endovascular coil embolization of cerebral aneurysm. Although protrusion of one or two coil loops may not cause adverse events and can be ignored in many instances, it can also compromise the parent artery in some cases with or without thrombus formation. We report a case of rescue balloon reposition of the protruding coil mass back into the aneurysm and recanalization of parent artery during embolization of the anterior communicating artery aneurysm.

Since sclerosing hemangioma of the lung was first described by Liebow and Hubbell in 1956, there have been several reports on cases occurring as a solitary nodule; however, sclerosing hemangiomas occurring as multiple nodules are extremely rare. The histogenesis of this tumor remains controversial and there are several hypotheses of the etiology. Three separate nodules were found in a 57-year-old housewife, one found in the right middle lobe, one in the apicoposterior segment of the left upper lobe, and one in the superior segment of the left lower lobe. The only symptom or sign presented was a dry cough. Apicoposterior segmentectomy of the left upper lobe and wedge resection of the superior segment of the left lower lobe were performed. The postoperative course was uneventful and the patient was discharged on the postoperative 15th day.

The Wallenberg's syndrome is produced by infarction of lateral medulla. Isolated ipsilateral axial lateropulsion without other common symptoms of Wallenberg syndrome has rarely been reported as manifestation of lateral medullary infarction. The responsible anatomical structure of ipsilateral axial lateropulsion is still uncertain. We describe a patient with lateral medullary infarction who present with isolated ipsilateral axial lateropulsion without other symptoms of Wallenberg syndrome.

Allergic fungal sinusitis (AFS) is a benign, noninvasive form of fungal sinusitis. Histologically, AFS is characterized by allergic mucin, which consists of eosinophilic mucinous material with occasional laminar deposits of eosinophils. A diagnosis of AFS can be made when there is a demonstration of characteristic allergic mucin and an appearance of fungal hypae scattered within the mucin with no evidence of tissue invasion, or when fungi cultures yield positive results. Until now, no cases of AFS have been reported in Korea, though there have been many cases of mycetomas and a few cases of invasive fungal sinusitis. We present the first two cases of AFS in Korea. The patients demonstrated characteristic allergic mucin, fungal hypae scattered within the mucin, and no evidence of tissue invasion on histopathology. Nasal polyps, involvement of the unilateral sinuses, peripheral eosinophilia, an elevated total IgE, and hyperattenuated masses observed in the CT supported the diagnosis of AFS. The patients recovered and did not display recurrence after surgery and treatment with topical steroids and saline irrigation.

Background:
Complex orbital fractures are impure orbital fractures because they involve the orbital walls and mid-facial bones. The author reported an orbital wall restoration technique in which the primary orbital wall fragments were restored to their prior position in complex orbital fractures in 2020. As a follow-up to a previous preliminary study, this study retrospectively reviewed the surgical results of complex orbital wall fractures over a 4-year period and compared the surgical outcomes by dividing them into groups with and without balloon restoration.
Methods:
Data of 939 patients with facial bone fractures between August 2018 and August 2022 were reviewed. Of these, 154 had complex orbital fractures. Among them, 44 and 110 underwent reduction with and without the balloon technique respectively. Pre- and postoperative Naugle exophthalmometer (Good-Lite Co.) scales were evaluated. The orbital volume and orbital volume ratio were calculated from preoperative and 6 months postoperative computed tomography images.
Results:
Among 154 patients with complex orbital fractures, 44 patients underwent restoration with the balloon technique, and 110 patients underwent restoration without it. The Naugle scale did not differ significantly between the two groups, but the orbital volume ratio significantly decreased by 3.32% and 2.39% in groups with and without the balloon technique and the difference in OVR was significantly greater in patients in the balloon restoration group compared with the control group. Postoperative balloon rupture occurred in six out of 44 cases (13.64%). None of the six patients with balloon rupture showed significant enophthalmos at 6 months of follow-up.
Conclusion
The balloon rupture rate was 13.64% (6/44 cases) with marginal screw fixation, blunt screws, and extra protection with a resorbable foam dressing. Furthermore, we restored the orbital wall with primary orbital fragments using balloon support in complex orbital wall fractures.
