Low back pain and sciatica is one of the most frequent and troublesome problem in or thropedic field. There are many controversies about surgicsl procedure for the treatment of the patient with herniated nucleus pulposus. The advantages of anterior interbody fusion are through removal of remnsnt of the disc, restoration of disc height, correction of spinal alignment, preservation of posterior elements and neural component. The strut of ilisc bone was firmly impacted and patients could be mobilization earlier. It is well known that symptoms secondary to herniated nucleus pulposus can resolve after disc excision and anterior interbody fusion, but little has been written about regression of herniated nucleus pulposus. We analysed 20 cases in which serial C-T studies disclosed an unequivocal regression or complete disappearance of nucleus pulposus after anterior interbody fusion. The results were summerized as followings ; 1. Regression of herniated nucleus pulposus was average 2.65mm. 2. The clinical results were excellent in 20% of the patients, good in 60% and fair in 20% 3. The comparision are based on the finding at C-T, marked regression(>4mm), was in 19%, moderate regression(2~4mm) in 59% snd minimal regression(<2mm) in 22%. 4. The clinical results were correlated to amount of regression of herniated nucleus pulposus.

Two cases with generalized G.A. were described. The first case was 42 years, old farmer representing slightly erythematous multiple papulonodular lesions on the face, neck, scapular areas, arms and dorsal hands. Coalescence of lesions in some areas of the dorsal hands and neck produced circinate or polycyclic pattern. The second case was 4 years old girl who developed purple to brown muliple papulonodular lesions and polygonal or round plague on the arms, dorsal hands, palms, neck, iliac crests, lower legs, dorsal feet and sole. The plague lesions mimick lichen planus.

A retrospective study was made of 10 consecutive patients who underwent mandibular reconstruction with PCBM from December 1994 to July 1996. Free autogenous iliac bone in the from of particulate cancellous bone and marrow was densely packed into the crib that was adapted to bridge the mandibular discontinuity defect. Frozen-treated autogenous mandibular bone, splitted autogenous rib, and titanium mesh(Dumbach, Leibinger) were used as cribs carrying the PCBM. All ten cases underwent successful healing with the formation of a continuous bony union with the remaining mandible. The rate of resorption was assessed by sequential panoramic radiographs. The mean horizontal dimension of the madibular defects was 44mm and the mean vertical dimension of the reconstructed segments was 23mm. The bony height of the reconstructed segments retained about 90% of the bony height of over a 1-year period. We confirmed that PCBM grafts were the most successful and predictable grafts in mandibular discontinuity reconstruction.

Archives of Craniofacial Surgery 2025;26(1):5-12
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.

Ganglioneruroblastoma and neuroblastoma are among commonest types of childhood malignancy and a number of unique paraneoplastic syndromes have associated with both localized and disseminated neuroblastoma. The coincidence of neuroblastoma and myoclonic encephalopathy or other paraneoplastic syndromes occurs relatively rare, and therefore, failure to recognize this association could result in delays in both diagnosis and treatment, and the result could prove to be unfortunately fatal. The mechanism which underlies the remote damaging effect of neural crest tumor, especially neuroblastoma, on the nervous system resulting in myoclonic encephalopathy is by no means clear. In addition the nature and the extent of the pathologic lesion are inconsistent. We experienced a case of myoclonic encephalopathy associated with an occult mediastinal ganglioneuroblastoma in a 22-month-old girl who was hospitalized for inability to walk without support and tilting of the head to the left side. She became increasingly ataxic, and during the hospitalization myoclonic jerks of upper extremities and head along with chaotic, rapidly flickering, multidirectional spontaneous eye movements, were noted. Laboratory data included normal complete blood count, urinalysis, BUN and creatinine, electrolytes and bone marrow. Chest X-ray and chest CT revealed a relatively well marginated right posterior mediastinal mass. In a 24 hours urine excretion test, VMA and catecholamines were increased. Over the next 2 weeks, a surgical exploration revealed a right posterior mediastinal mass. Microscopically the mass proved to be a ganglioneuroblastoma, extending to right innominate artery and right axillary lymph nodes. Within 2 weeks after the surgery, radiotherapy (2,400 rads) and chemotherapy (CTX, DTIC, VCR) were started, but corticosteroid was not used. She has been free of tumor and abnormal neurological systemic symptoms and signs for 1 1/2 year since the completion of chemotherapy. In the 3 1/2 years follow-up period, her neurologic symptoms has completely resolved by the completion of 2 years chemotherapy. We report a case of mycoclonic encephalopathy associated with hidden ganglioneuroblastoma in 22-month-old girl.

Congenital adrenal hyperplasia is inherited disorder of adrenal steroidogenesis. 21-hydroxylase deficiency is the most commone enzymatic defect and is divided into classic and late-onset or nonclassic forms. Both classic non-classic 21-hydrozylase deficiencies are inherited in a recessive manner as allelic variants. But it is rare that happened in twin infants. Chief complaints of affected twins in our case were ambiguous genitalia, hyperpigmentation and dehydrations. They were revealed into hyponatremia, hyperkalemia and increased amount of serum progesterone, 17-hydroxyprogesterone and urinary 17-ketosteroid excretion and were administered with DOCA, 9alpha-fluorohydrocortisone, hydrocortisone to control the electrolyte imbalance. And now, both of them are going to normal ratio of weight gain and body growth.
