2.Associations between Orbital Morphology and Exophthalmos Changes after Endoscopic Orbital Decompression to Treat Thyroid-related Orbitopathy
Journal of the Korean Ophthalmological Society 2023;64(5):359-366
Purpose:
To investigate orbital morphology parameters associated with exophthalmos changes in patients undergoing endoscopic orbital decompression to treat thyroid-related orbitopathy.
Methods:
In total, 33 eyes of 18 patients with thyroid-related orbitopathy who underwent endoscopic orbital decompression were included in this retrospective study. Data were collected before and 6 months after surgery. We performed Hertel exophthalmometry and derived orbital morphology parameters from two-dimensional facial computed tomography records. Parameters associated with exophthalmos reduction on univariate linear regression analysis were subjected to multivariate linear regression analyses.
Results:
Univariate linear regression showed that the preoperative length of the medial orbital wall (β = 0.179, p = 0.032) and the postoperative distance from the cone apex to the medial wall defect (β = -0.139, p = 0.006) were associated with exophthalmos reduction after endoscopic orbital decompression surgery. Multivariate linear regression of these two parameters showed that the distance from the apex to the medial wall defect was associated with exophthalmos reduction (β = -0.118, p = 0.019).
Conclusions
The postoperative distance from the cone apex to the medial wall defect was associated with exophthalmos reduction. In patients with thyroid-related orbitopathy, this association should be considered when planning endoscopic orbital decompression.
3.Traumatic Blindness Due to Injury of Internal Carotid Artery Associated with Craniomaxillofacial Fracture.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 2003;30(3):351-354
A case of traumatic internal carotid artery injury associated with skull base fracture, Le Fort II fracture and mandible fracture after maxillofacial blunt trauma which resulted in delayed blindness is presented. This condition would appear to be a rare consquence of maxillofacial trauma. Internal carotid artery injury including dissection is an important consequence of blunt craniomaxillofacial trauma with potentially devastating consquences. It should be emphasized that skull base fracture involving the course of the internal carotid artery provides an important clue to significant vascular injury and, when present, provides the impetus for vascular imaging study.

PURPOSE: To report and review several cases of uncommon ocular manifestations in neurofibromatosis patients. CASE SUMMARY: A 19-year-old woman diagnosed with type 2 neurofibromatosis visited our hospital with amblyopia of the right eye and mild visual disturbance of the left eye. Best corrected visual acuity was 20/250 in the right eye, 20/25 in the left eye and relative afferent pupillary defect in the right eye was observed. Fundus examination of both eyes showed papilledema. Magnetic resonance imaging showed schwannoma from the optic nerve to the optic chiasm. A 28-year-old woman diagnosed with type 2 neurofibromatosis visited our hospital with amblyopia of the right eye. Best corrected visual acuity was finger count in the right eye, 20/20 in the left eye and relative afferent pupillary defect in the right eye was observed. Fundus examination of the right eye showed a slightly elevated lesion at the macula, as well as dragged optic disc and retinal vessels to the macula. An 8-year-old girl diagnosed with type 1 neurofibromatosis visited our hospital with enophthalmos and strabismus of the left eye. On exophthalmometry, enophthalmos in the left eye was found; measurements were 15.0 mm in the right eye and 13.0 mm in the left eye. Three-dimensional computed tomography revealed sphenoidal hypoplasia and a left lateral orbital wall defect. CONCLUSIONS: The authors of the present study report on neurofibromatosis patients who had an uncommon ocular manifestation. Neurofibromatosis can represent various ocular manifestations but reports of compressive optic neuropathy, dragged disc syndrome and sphenoidal hypoplasia are rare.

BACKGROUND AND OBJECTIVES: Patients with aspirin-exacerbated respiratory disease (AERD) tend to have more severe clinical course and also tend to be recalcitrant to conventional medical and surgical treatment. This study aimed to assess the long-term outcome of endoscopic sinus surgery in AERD patients. SUBJECTS AND METHOD: Fifteen patients with AERD (n=15) were identified through a retro-spective chart review, and compared with 74 patients of CRSwNP (with asthma n=23; without asthma n=51) by analyzing preoperative and postoperative symptoms, endoscopic score, Lund-Mackay CT score, number of revision surgery or outpatient procedures, frequency of clinic visits and medications. The CRS control status was evaluated according to the European Position Paper on Rhinosinusitis and Nasal Polyps 2012 criteria and logistic regression analyses were conducted to investigate the determining factors of preoperative and postoperative symptoms. RESULTS: The AERD group showed higher disease severity than other groups preoperatively: endoscopic score (CRSwNP s asthma 6.3±2.6 vs. CRSwNP c asthma 6.5±2.3 vs. AERD 8.8±1.4, p<0.05), CT score (12.2±4.9 vs. 17.0±4.8 vs. 18.0±2.1, p<0.05), and overall symptom score (30.8±0.4 vs. 33.8±1.5 vs. 37.9±0.7, p<0.01). The rate of revision surgery and outpatient procedures, postoperative clinic visit and prescription rate were higher in the AERD group (p<0.05, respectively). However, postoperative symptom scores and CRS control status were not significantly different among three groups (p=0.267 and p=0.996, respectively). CONCLUSION: Although AERD patients showed higher preoperative endoscopic scores and revision surgery rates, postoperative subjective symptoms were comparable to those of other groups with long-term follow up, suggesting the importance of frequent outpatient care after endoscopic sinus surgery.

PURPOSE: The purpose of this study is to investigate the usefulness of ultrasound-guided femorosciatic nerve block by orthopaedist to operate the fracture around ankle. MATERIALS AND METHODS: Twenty-two patients, who had an operation for fracture around the ankle under a ultrasound-guided femorosciatic nerve block from January to April 2010, were the targets of this study. We measured the time spent for the ultrasound-guided femorosciatic nerve block, the time taken to start the operation after the nerve block, the time taken to deflate the tourniquet because of a tourniquet pain, the time passed until feeling a postoperative pain after the operation, etc. We also studied the complications and satisfaction of the anesthesia. RESULTS: It took 6.2 (3 to 12) minutes for the nerve block, 46.1 (28 to 75) minutes to start the operation, 52.5 (22 to 78) minutes until feeling a tourniquet pain and 11.5 (7.5 to 19) hours until starting to feeing a postoperative pain. There was no complication by anesthesia and 21 people (95.5%) were satisfied with anesthesia by ultrasound-guided femorosciatic nerve block. CONCLUSION: Ultrasound-guided femorosciatic nerve block by orthopaedist in the fracture around ankle reduces anesthetic and nerve injury complication, and leads to high anesthetic success rate. Also it is considered as an effective method to alleviate postoperative pain.

PURPOSE: To evaluate the usefulness of separate vertical wirings for extra-articular fracture of distal pole of patella. MATERIALS AND METHODS: We have analyzed the clinical results of 18 cases that underwent separate vertical wirings for extra-articular fracture of distal pole of the patella from March 2005 to March 2010, by using the range of motion and Bostman score. Occurrence of complication was also evaluated. Additionally, by taking simple radiographs, the correlation between the postoperative degree of anterior transposition of bone fragment and the time of bone fusion, preoperative length of bone fragment, and occurrence of comminuted fracture were investigated. RESULTS: It took an average of 13.8 weeks for radiological bone union after separate vertical wiring fixation. Flexion contracture was an average of 0.8 degrees and further flexion was an average of 127.6degrees, and Bostman score was an average of 27.5 points (excellent in 12 cases, and good in 6 cases). On the first postoperative year, average flexion contracture was 0.6 degrees and further flexion was an average of 136.3degrees, which exhibited increased joint motion and recovery to normal range of motion, and Bostman score was an average of 28.7 points (excellent in 16 cases, and good in 2 cases). There was no statistically significant difference between the preoperative bone fragment length and presence of comminution, and degree of anterior transposition of bone fragment after fracture union on simple radiograph (p=0.175, p=0.146). CONCLUSIONS: We were able to obtain satisfactory clinical results, while preserving the bone fragment by separate vertical wiring fixation for extra-articular fracture of distal pole of patella. Moreover, the method is easy to perform, which is also considered as a useful surgical method for extra-articular fracture of distal pole of patella.

OBJECTIVES: Recent studies have suggested that the personality and communication style of the mother can affect the progress of disease in children with chronic illnesses. The current study assessed the characteristics, attachment type and communication skill of mothers who have children with alopecia areata that may concern their children. METHODS: The subjects of this study were 46 mothers of children with alopecia areata (alopecia children: mean age 7.52+/-3.41yrs ; 27 males, 19 females), who visited the alopecia clinic at the Dermatology Department of Chung-Ang University Hospital, and 42 mothers of normal children (control children : mean age 6.85+/-0.46 yrs; 20 males, 22 females). The Minnesota Multiphasic Personality Inventory (MMPI) subscale, the Revised Adult Attachment Scale (RAAS), the Parent Adolescent Communication Inventory (PACI), and the Campbell Index of Well-Being were administered to all the subjects for the purpose of comparing the mothers of the alopecia group with those of the normal controls. RESULTS: There were no differences in socio-demographic characteristics between the alopecia and control group mothers. The MMPI scores of both groups were within the normal profile ranges, but the scores of the mothers in the alopecia areata group were significantly lower than those in the control group mothers on the Pd(4), Mf(5), and Ma(9) subscales (p=0.028, p=0.001, p=0.005 respectively). There were significant differences in communication style between the two groups. Alopecia group mothers showed less open family communication (p=0.034) and more problems in family communication (p=0.000) than the control group mothers. The scores on problems in family communication were positively correlated with Pd(4) scores (r=0.48, p=0.03). An insecure attachment style was more common in the alopecia group mothers than in control group mothers (p=0.023). There was no difference between the two groups of mothers on the Index of Well-Being. CONCLUSION: Compared with the mothers of control group children, the mothers of children with alopecia areata had more depressed and suppressed personality characteristics not expressing their psychological conflicts directly (low Pd, Mf, and Ma scores), more problems in family communication with their children and more insecure attachment type. We suggest that these results should be considered in the treatment of children with alopecia, and that psychological intervention for their mothers is needed.

Hip & Pelvis 2012;24(2):102-108
PURPOSE: To analyze, by radiograph, the difference in bone mineral density (BMD) and the proximal femoral morphology of females who are over 65 years old and have had either an intertrochanteric fracture or a femoral neck fracture. MATERIALS AND METHODS: One hundred twenty-five females over 65 years of age with femoral neck fractures or intertrochanteric fractures were examined for bone mineral density using computed tomography from April 2008 to March 2011. The bone mineral density was measured by dual-energy x-ray absorptiometry (DEXA). The morphology of the proximal femur was also measured by computed tomography in the unaffected hip. RESULTS: In the femoral neck fracture group, the mean BMD value was 0.563 g/cm2 in the femoral neck region and 0.753 g/cm2 in the intertrochanteric region. In the intertrochanteric fracture group, the mean BMD value was 0.457 g/cm2 in the femoral neck region and 0.656 g/cm2 in the intertrochanteric region. There are statistically significant differences between the femoral neck fracture and intertrochanteric fracture groups (P=0.029, 0.030). The mean cortical index was 0.59 in the femoral neck fracture group and 0.51 in the intertrochanteric fracture group. There are statistical differences between the femoral neck fracture and intertrochanteric fracture groups (P=0.001). CONCLUSION: The BMD of the proximal femoral neck and intertrochanteric regions of the intertrochanteric fracture group were significantly lower than that of the femoral neck fracture group. The cortical index was also significantly lower in the intertrochanteric fracture group than the femoral neck fracture group. BMD and computed tomography seem useful to check in women older than 65 who have fractures of the proximal femur.
