PURPOSE: Studies reported controversial results about prognosis of root resection with 0%-38% failure rate. The purpose of this study is to consider clinical efficacy of root resection. MATERIALS AND METHODS: This study reported three cases of root resection which were performed on different sites. In first case, lower right first molar showed pus discharge and 7 mm of probing pocket depth. It was diagnosed as fracture of mesial root. Hemisection of mesial root was performed In second case, upper right first molar showed severe bone loss on disto-buccal root and 7 mm of probing pocket. Resection of disto-buccal root was performed In third case, lower left second molar showed severe bone loss on distal root including apex and 15mm of probing pocket depth. Hemisection of distal root was performed. RESULT: In these three cases of root resection, compromised molars were treated successfully and conserved. CONCLUSION: Root resection is a successful procedure treating compromised multi-rooted teeth and conserving teeth when proper case selection is performed.

The estimated incidence of recurrent or residual cholesteatoma requiring revision mastoid surgery ranges from 2% to 10% in canal wall down mastoidectomy. The causes of failure of mastoidectomy include recurrent cholesteatoma, suppuration in unexentrated cells, and mechanical factors promoting retention of debris within the mastoid cavity. The authors have experienced a case of long-term residual cholesteatoma, without connection to the previous radical mastoidectomized cavity, which showing subscalp fistula and extradural granulation with continuous purulent discharge. So we report with a review of literature.

OBJECTIVE: The aim of this study is to assess the significance of an apparent diffusion coefficient(ADC) study for diagnosis of ventriculitis. METHODS: Seven patients with ventriculitis were enrolled in this study. Diffusion-weighted(DW) magnetic resonance images(MRI) and ADC maps in the dependent intraventricular collection, periventricular white matter and non-dependent cerebrospinal fluid(CSF) were obtained. The images and ADC data from the different lesions were compared. RESULTS: The DW MRI showed marked hyperintensity in the purulent pus lesion, and the corresponding ADC maps revealed prominent hypointensity and restricted ADC values compared with the non-dependent CSF and normal white matter. CONCLUSION: The decreased ADC value and increased signal intensity of the dependent intraventricular fluid on the DW MRI show restricted water diffusion in the purulent fluid, which is indicative of a pyogenic ventriculitis diagnosis.

BACKGROUND AND OBJECTIVES: There have been many studies concerning histologic changes and effectiveness of specific treatment in the experimentally induced sinusitis model, but there are few studies about natural course of paranasal sinusitis. This study aimed to analyze the natural course of sinusitis and the influence of stress on the natural disease course. MATERIALS AND METHOD: Natural ostia of 120 rabbits were occluded and reopened at 10 days after occlusion. Rabbits were divided into six groups according to duration from reopening to sacrifice. Each group was sacrificed at 1, 4, 8, 12, 19, 26 days after reopening of the natural ostium. Each group was divided into a control and stress subgroups. Radiologic, gross and histologic findings were analyzed. RESULTS: Percentage of rabbits showing partial or total haziness was highest at 3 days after reopening in the control subgroup and at 11 days in the stress subgroup. Percentage of the rabbits showing moderate or severe amount of pus in the sinus on gross examination was highest at 4 days in both subgroups. Degree of epithelial loss was most severe at 4 days in both subgroups. Subepithelial thickness was largest and inflammatory cell infiltrations were most severe at 8 days in both subgroups. Although there was a lack of statistical significance, stress subgroups showed more severe gross, radiologic, and histologic findings than those of control subgroups. CONCLUSION: This study shows that maxillary sinusitis is induced by natural ostium occlusion only and is improved with time without any treatment, and that stress might influence the severity of maxillary sinusitis.

Traumatic rupture of the corpus cavernosum of the penis is rare and has been reported infrequently. We experienced 4 cases of penile fracture for recent 2 years. They occurred during coitus(1 case), masturbation(2 cases), and through blunt trauma(1 case). The former 3 cases were treated with immediate surgical intervention about 12 hours after injury. When the last case patient visited hospital 5 days after injury, the penile abscess treated immediately with surgical intervention had developed. Surgery consisted of complete evacuation of the hematoma or pus and repairing of the tear at the tunica albuginea. The results were excellent, with complete early recovery of erectile function. Delayed wound healing was observed only in a patient who underwent surgery about 5 days after injury, but this did not cause any complication afterward. In our experiences, immediate surgical treatment is recommended in patients with fracture of the penis.

STUDY DESIGN: Infectious spondylitis patients were classified according to their cause in pyogenic and tuberculous and compared by each. SUMMARY OF LITERATURE REVIEW: Tuberculous spondylitis shows chronic clinical course and disc space sparing with much pus formation in radiologic finding compared to pyogenic spondylits. PURPOSE: To compare pyogenic and tuberculous spondylitis in clinical, radiological, pathological difference for appropriate management of infectious spondylitis. MATERIALS AND METHODS: We reviewed sixty two cases of infectious spondylitis confirmed by culture and pathologic findings of specimens which obtained by surgical method at the orthopaedic department of the Dong-A university hospital between June 1990 and November 1998. RESULTS: There were 18 cases of pyogenic and 44 cases of tuberculous spondylitis, and combined infection case was absent. Average period between beginning of symptom and diagnosis was 6.4 months in pyogenic spondylitis(4-11 months), 3.9 months in tuberculous spondylitis(3-39 months). The average number of affected vertebra was 2.3 in pyogenic spondylitis and 3.9 in tuberculous spondylitis. 6 cases of pyogenic spondylitis(33%) showed high fever(above 38degree C) which not presented in tuberculous spondylitis. We could not find considerable difference in leukocyte count, ESR, CRP level and simple radiologic finding, MRI finding between pyogenic and tuberculous spondylitis. CONCLUSIONS: In our study, most pyogenic spondylitis shows chronic and inactive feature, so clinical, radiological, laboratory findings are not appropriate guide to differentiate between pyogenic and tuberculous spondylitis. Culture growth of infecting agent and histologic examination are reliable and essential diagnostic method for pyogenic and tuberculous spondylitis.

This is to report a case of immediate reconstruction after hemimandibulectomy by using of bicorticocancellous block bone harvested from the iliac crest in the case of an ameloblastomaon the mandible. Because the lesion involved condylar area, it was reconstructed with titanium artificial condyle attached to A/O metal plate. Three weeks after the operation, infection developed with suppuration and was well treated with adequate antibiotic therapy and drainage. The patient has been followed up over a four-year period and taken an orthopantomogram every three or six month for the examination of mandibular movement, the potentiality of recurrence and the remodeling of the grafted bone. At present, the patient is satisfied with her appearence and has a normal occlusion with proper masticatory function, and there is no sign of recurrence.

Chronic osteomyelitis is often considered difficult to treat and may lead to refratory condition in oral and maxillofacial region. Clinical features of chronic osteomyelitis includes pain, swelling, pus discharge, and radiographic change. There are many kinds of treatment of chronic osteomyelitis. One of the most important factors in treating osteomyelitis are removal of infectious foci and administration of massive antibiotics. Recently we reviewed 29 patients with chronic osteomyelitis who visited in our department and treated successfully with our treatment protocols, consisting of surgical intervention and intravenous antibiotics for 2 weeks, and followed by oral antibiotics for 6 weeks. It is concluded that combination of surgical intervention and antibiotic therapy are sufficient to treat the chronic osteomyelitis in oral and maxillofacial region.

PURPOSE: Regional lymphadenitis is the most common complication of BCG vaccination and has various clinical course and prognosis, but there are no accurate guidelines for the management BCG lymphadenitis. This study was performed to reveal the clinical course of BCG lymphadenitis and provide guidelines for its management by comparison of observation and medication groups. METHODS: Between January, 2002 and April, 2003, 45 patients with non-suppurative lymphadenitis were reviewed. They were divided into two groups, and retrospectively compared. Group I consisted of 25 observation cases and group II of 20 antituberculous medication cases. RESULTS: The most prevalent age group of the 45 cases was three months old, and the most prevalent site of lesion was the ipsilateral axilla. A palpable single lesion was the most common finding. According to treatment (observation vs. antituberculous medication), the medication did not affect the prevention of suppuration. CONCLUSION: For the management of BCG lymphadenitis, systemic antituberculous medication and observation are not recommended, with active surgical resection being the treatment of choice.
