JOURNAL FREE ACCESSThis study was carried out to evaluate the relation shipbetween the effect of preoperative radiotherapy for oral cancer and the changes of signal intensity with MR images. T2-weighted images were compared before and after radiotherapy in 18 patients with primary oral cancer, and the effect on the lesions was histologically evaluated in surgically resected speci mensobtained four weeks after the therapy. The MR images showed significantly decreased signal intensity of the lesions. The decrease of signal intensity was remarkable starting at two weeks after completion of the radiotherapy, compared with the decrease at less than two weeks after the therapy. The change of signal intensity was more obvious in tongue cancer than in other oral cancers. There was no significant difference in the change of the signal intensity be tweencancers with histologically poor response to the therapy and those with good response.
These results suggested that signal intensity of oral cancer on T2-weighted images showed a significant decrease after preoperative radiotherapy, and that the intensity could be affected by duration after radio therapyand primary sites.View full abstractDownload PDF (1097K) -

JOURNAL FREE ACCESSThe purpose of this study was to evaluate the effects of maxillary growth of patients with complete bilateral cleft lip and palate (BCLP) treated by twostage palatal repair combined with a Hotz's plate.
The subjects were 26 BCLP patients from 5 to 12 years of age who had received two-stage palatal repair combined with a Hotz's plate (TSPR). Serial maxillary casts were used to analyze and compare with those of 34 BCLP treated by one-stage palatal repair (OSPR), and 24 normal children without any clefts (NC).
The results were as follows:
1. The length and width of the maxillary arch in the TSPR group were the same as for the NC group in patients from 5 to 6 years of age (before hard palate closure).
2. From 7 to 12 years of age (after hard palate closure), the length of the maxillary arch grew gradually in the TSPR group, just like in the NC group. The maxillary width tended to be slightly smaller in the TSPR group than in the NC group. On the other hand, the incidence of cross bite in lateral dentition was lower in the TSPR group than in the OSPR group.
It was concluded that two-stage palatal repair combined with a Hotz's plate was effective for maxillary growth in bilateral cleft lip and palate patients.View full abstractDownload PDF (1586K) -

JOURNAL FREE ACCESSThere appear to be only a few reports detailing the etiology and pattern of facial fractures in females in the English published literature. To delineate this problem, we conducted a retrospective analysis of female patients with facial fractures who visited the Department of Oral and Maxillofacial Surgery Clinic, University of the Ryukyus Hospital, during the 16 years from January 1985 to December 2000. The age range was 3 to 87 years (mean, 29 years), with the peak incidence occurring in the age group of 20 to 29 years. Road traffic accidents were the primary etiology, followed by falls, and assaults. The mandi blewas the most commonly injured facial bone, followed by the zygomatic complex. Alcohol abuse was a contributing factor in 22.6% of the female patients, and 44.4% of assaults were related to alcohol consumption. Compared to males, more females sustained facial fractures in the age groups of under 10 years and over 40 years, caused by road traffic accidents and falls. Moreover, female cases showed high incidence rates of motor vehicle accidents (32.9%) and being passengers (17.1%), compared with 19.4% and 7.3% of male cases, respectively, in the etiology of road traffic accidents. On the other hand, in patients who sustained facial fractures caused by assaults, it showed high incidence rates of 20-29, 40-69 age groups, and more female than male suffered a fracture of the zygomatic complex (27.7% vs. 8.1%).View full abstractDownload PDF (849K) -

JOURNAL FREE ACCESSA case of endophthalmitis caused by an oral bacte riumis presented. A 53-year-old man visited the department of ophthalomology complaining of de creasedvisual acuity, and a diagnosis of endophthal mitiswas made. Initial blood examination showed that he had severe diabetes (HbA1c 11.6%, blood sugar 394mg/dl) and severe inflamation (white blood cells 17, 420/μl, C-reactive protein 18mg/dl). He was referred to our department for oral examination and care, because no infection focus was found elsewhere on his body, andStreptococcus agalactiae (group B streptococci) was detected in a blood culture. His oral hygiene was poor, and severe periodontitis was found. An oral adherent smear culture revealedS. agaractiae (group B streptococci). The patient was treated with antibiotics and an antifungal agent. Further, insulin therapy was started for his diabetes at the same time. Nine days after his first visit to us, nine teeth with severe periodontitis were extracted.Then, his general condition improved, and the white blood cell number and value of C-reactive protein decreased. After surgery on both eyes, he recovered vision to 0.2 in his left eye, but lost sight in his right eye.View full abstractDownload PDF (532K) -

JOURNAL FREE ACCESSFacial bone fracture with coexisting injury is not a rare occurrence. We are occasionally compelled to change the treatment plan for a facial bone fracture because of serious coexisting injuries. We could not perform open surgery for a zygoma and maxillary fracture under general anesthesia, due to pulmonary injury, and therefore treated the case with a conserva tivemethod of extraoral traction with Halovest. The duration of the traction period was 25 days, which led to good results in both reduction and fixation of fractured bone pieces. After two years and ten months, the patient has no functional or aesthetic trouhle.View full abstractDownload PDF (2102K) -

JOURNAL FREE ACCESSWe report five cases of oral mucosa injuries from unusual causes. A puncture wound of the hard palate due to a bee sting, an abscess of the tongue after it was punctured by a fish bone, a scald of the oral mucosa caused by mistaking a firecracker for hina arare (small rice-cake balls), a burn of the upper lip and gingiva caused by a skyrocket that rebounded off the ground, and a laceration caused by a toothbrushingarm being kicked, are described.
The clinical findings and treatments for these injuries are discussed.View full abstractDownload PDF (2986K)
