Common Extensor Fasciotomy and Radial Nerve Decompression on Recurrent Lateral Epicondylitis

PURPOSE: This study was performed to evaluate the results after a combined surgical treatment of common extensor Fasciotomy & Radial nerve decompression in recurrent lateral epicondylitis patients. MATERIALS AND METHODS: We retrospectively reviewed the functional records of 6 cases of patients who were treated surgically from the February 2004 to June 2008. 2 cases had Radial tunnel syndrome, and The average duration from the time of diagnosis until operation was 23.5 months (7~38), the patients were given an average of 5.7 local steroid injections each, and they were followed up postoperatively for at least 1 year. We performed combined surgical treatment of common extensor Fasciotomy & Radial nerve decompression. The patients' pain intensity was evaluated by VAS score system before the operation, 6 months and 12 months after the operation. The objective assessment of the surgery was investigated according to the criteria by Roles and Maudsley. RESULTS: The grasping power of the lesion site was 11.7 before surgical treatment, 18.6 and 28.3 after 6 months and 12 months. The mean VAS score was 8.2 before surgical treatment, 4.2 and 1.3 after 6 months and 12 months, respectively. The mean Simple Elbow Test Score was 1.8 before operation, 7.0 and 10.3 after 6 and 12 months, respectively. In clinical evaluation by the Roles and Maudsley's Criteria, there were 3cases assessed as excellent and 3 cases assessed as good after 12 months of follow up. No recurrence was noted and all the patients returned to the occupational activity and the average duration was 4.5 months. CONCLUSIONS: The surgical treatment using common extensor fasciotomy and radial nerve decompression for recurrent lateral epicondylitis is considered to be one of the recommendable methods.

Immunohistochemical Study between Extracellular Matrix Protein Tenascin and T Lymphocytes Distribution in Cholesteatoma / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Components of extracellular matrix protein play a crucial role in morphogenesis and epithelial cell differentiation. Protein is highly conserved during evolution and is expressed in a variety of tissues, and the amount of T and B lymphocytes are significantly higher in cholesteatomatous tissue than in the external auditory canal skin. We examined the spatiotemporal expression and distribution of extracelluar matrix protein tenascin and lymphocytes of cholesteatomatous tissue and normal external auditory canal skin. MATERIAL AND METHODS: The biopsy specimens of cholesteatomatous tissue and external auditory canal skin were obtained during middle ear surgery. Monoclonal mouse antibodies against tenascin, CD4 helper cell and CD8 cytotoxic/suppressor T cells were used. RESULTS: The results are as follows: 1) The expression of tenascin was significantly increased in cholesteatomatous tissue compared to that in normal external auditory canal skin. 2) As the expression of T lymphocytes increased, the expression of tenascin increased significantly (p<0.05, r=0.832). 3) As the expression of Langerhans' cells increased, the expression of tenascin increased significantly (p<0.05, r=0.788). CONCLUSION: These results suggest that the change in the composition of the extracelluar matrix protein and lymphocyte in cholesteatomatous tissue may play an important role in the pathogenesis of cholesteatomatous otitis media.

A Case of Nasopharyngeal Mesenchymoma / 대한이비인후과학회지

The benign mesenchymoma, in which fibrous tissue is accompanied by two or more mesencymal components, occurs very rarely in the head and neck area. The majority appear in patients under 25 years of age, most commonly in the subcutaneous scalp, cheek, or tongue. There is a 20% recurrence rate. Wide surgical excision is the treatment of choice. We report a case of mesenchymoma in the nasopharynx which was removed by transpalatine approach with a brief review of literature.
