Trigeminal motor neuropathy is a rare disorder which involves only motor fiber in trigeminal nerve. We experienced a 58-year-old man with muscle weakness and wasting of left masticatory muscles for 3 weeks. He had suffered from the same event on the right side 13 years ago. He had no sensory dysfunction and Brain CT revealed no gross abnormality. All the laboratory findings were negative and the EMG revealed chronic denervating process in bilateral masseter and temporalis muscles. He has improved after steroid therapy.

We analyzed 177 diabetic patients(80 males, 97 females) with the nerve con duction study (NCS) performed twice or more at the interval of more than one year in Severance Hospital from Jan 1, 1984 through Dec 31, 1994. We conclude as follows: 1)The NCS follow-ups showed that diabetic polyneuropathy was getting worsened electrophysiologically as time goes by. 2)The NCS revealed that the earlier change was noticed on the distal portion of sensory nerve fiber, though diabetes was known to cause a damage to both sensory and motor nerve fibes. 3)Considering that the NCS follow-ups revealed earlier and more marked changes in amplitude than in nerve conduction velocity, axonal degeneration seems to be more responsible for the pathogenesis of diabetic polyneuropathy rather than segmental demyelination.

PURPOSE: This study was designed to verify intermediate-term functional and radiological results of limb salvage operation using endoprosthetic replacement system (MUTARS(R)) used in patients with a malignant bone tumor. MATERIALS AND METHODS: Thirty one cases which used MUTARS(R) tumor prosthesis were reviewed. The mean age of the patients was 49.2 years and the mean follow up was 39.8 months. We retrospectively reviewed complications, and evaluated functionally and radiologically by Enneking functional score, ISOLS radiological implants evaluation system at last follow-up. RESULTS: 3 patients had died of disease, distant metastasis was seen in 4 patients and local recurrence was seen in 1 patients. Complications were developed in 12 patients. (infection 6, leg length discrepancy 2, aseptic loosening 2, periprosthetic femoral fracture 1, screw loosening 1) Mean value of total functional scores were 81.2% in proximal femur, 77.4% in distal femur, 78.1% in proximal tibia, and 80.2% in proximal humerus. The overall radiological result was relatively satisfactory. CONCLUSION: Our results suggest limb salvage with the MUTARS(R) endoprosthesis is successful with good functional and radiological results. But we should be careful with complications such as infection.

Prediction of acetabular development after reduction in treatment of developmental dysplasia of thc hip (DDH) is earlier, the hetter results because it would help ensure optimal timing of additional procedure if necessary. In this respect, authors reviewed retrospectively the radiographs of the hips of 35 children with DDH who had unilateral involvement and treated hy senior author (S.H.Lee) from the heginning with single successful attempt of reduction. The radiographs which were made at the time of initial diagnosis, one, two year nfter reduction und final follow up were assessed of teardrop figures. The results of treatment were classified as satisfactory group(CE > 10degrees ) and unsatisfactory group(CE < 10degrees) judged hy center-edge angle(CE degrees) at final follow-ups. 1. The teardrop figures were classifiable into 4 distinct groups as i)absent. ii)V-shaped, iii)Ushaped, iv) inverted D-shaped. 2. The teardrop figures in normal sides of hip were all U-shaped. 3. In dislocated but with satisfactory result group(24 cases), absent at 2 cases(8%), U-shaped teardrop was seen at 13 cases(54%), V-shaped in 9 cases(38%), and inverted 2-shaped in 0 case at I year after reduction. 4. In dislocated but with unsatisfactory result group( 11 cases), they were mostly of V-shaped(7 cases, 64%). The rest were of ahsent in 4 cases(36%) . hut none of U-shaped and inverted 2-shaped. In conclusions, teardrop figures appeared as significant predictor of future development of hip joint. Teardrop figure which stay as V-shaped at one year after reduction seems suggestive of insufficient reduction of DDH, therehy calls for early additional procedure.

The carpal injury is difficult to diagnose due to anatomical complexity and the like. So, in order to get radiological knowledge of normal wrist, the authors measured the values which will be described on the wrist PA and lateral roengenogram obtained from 440 normal wrists(male : 188 cases, female : 252 cases) in randomly selected patients. The following results were obtained. l. Ulnar variance(mm±standard deviation): Total 1.1±1.2 : negative variance : 9.3%, positive variance : 56.1%, 2. Scapholunate Gap(mm±standard deviation): Total 0.4±0.7, 3. Ulnar Tilt(degrees±standard deviation): Total 23.6±5.3, 4. Volar Tilt, 5. Carpal height rstio : Total 0.52±0.05 male 0.53±0.04 female 0.51±0.05 : Total 13.1±5.9, 6. Carpal ulnsr distance ratio Total 0.05±0.05, 7. Scapholunate Angle : Total 49.9'±10.1', 8. Capitatolunate Angle Total 17.5'±10.0', 9. Radiolunate Angle Total 8.8'±6.7', 10. Carpal width ratio Total 0.72±0.08 11. Carpal thickness ratio Total 0.49±0.07.

Spinal instrumentation using pedicle screws offers several advantages such as 1) achievement of rigid fixation through the pedicles which is the strongest structure of spine, 2) nearly anatomic reduction by direct force on the deformed sites of fracture and 3) preservation of mobile segments by short segment fixation. The authors analysed 14 cases of unstable thoracolumbar and lumbar fracture treated by pedicle screw fixation from May 1988 to June 1989. Mean follow up was 14 months(8M.-20M.) and following results were obtained. 1. Most of the cases were male(13 cases) and their age ranged from 26 to 55 with an average of 36. 2. According to Denis classification, there were 7 cases of burst fracture, 5 cases of fracture-dislocation, 1 case of seat belt injury and unclassified one case. 3. After operation, the height of anterior column was reduced from 61% to 86%, posterior column, from 134% to 105%, local kyphosis, from 17.4% degrees to 3.4 degrees and anterior translation, from 6mm to 1.2mm. 4. In comparision of preoperative and postoperative moter index between fracture-dislocation and burst fracture, the former changed from 3.2 to 21.8 and the latter, from 40.2 to 48.6. 5. Significant neurologic recoveries were observed in all cases except one complete paraplegia. 6. There was no significant complication and minimal loss of correction was noted.

7.Hearables as a Gateway to Hearing Health Care
Clinical and Experimental Otorhinolaryngology 2022;15(2):127-134
The market for hearing technology is evolving—with the emergence of hearables, it now extends beyond hearing aids and includes any ear-level devices with wireless connectivity (i.e., wireless earbuds). However, will this evolving marketplace bring forth opportunities or challenges to individuals’ hearing health care and the profession of audiology and otolaryngology? The debate has been ongoing. This study explores the wide spectrum of hearables available in the market and discusses the necessity of high-quality clinical evidence prior to the implementation of over-the-counter devices into clinical practice.
