The patient was a 35-yearold male who fell off the surfboard into the sea with the fin hitting hard the patient’s right eye. The patient had right ptosis, pain on looking upwards, and forehead paralysis. No bruises on the head or face other than the lower eyelid were noted. The orbital computed tomography scan showed that only the orbital roof was fractured, the bone fragments cranially deviated, and the orbital fat was incarcerated in the fracture site. The patient underwent surgery using the transpalpebral supraorbital rim approach on day 14 postinjury. The fracture was of the trapdoor type, and the orbital fat, levator palpebrae superioris muscle, and supraorbital nerve were strangulated at the fracture site. Ptosis and eye movement disorder quickly improved postoperatively. Isolated orbital roof blowout fracture, trapdoor type, is a rare condition, and the fracture can be repaired using the transpalpebral approach in the absence of intracranial lesions and extensive bony deviation.","PeriodicalId":23019,"journal":{"name":"The Showa University Journal of Medical Sciences","volume":"70 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89376778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kagami","doi":"10.15369/sujms.34.11","DOIUrl":"https://doi.org/10.15369/sujms.34.11","url":null,"abstract":"Understanding respiratory motion is necessary for accurate dose administration during stereotactic body radiation therapy. Although four-dimensional (4D) computed tomography (4DCT) is useful for understanding respiratory movements, 4D radiotherapy with a time axis is required. However, reports on the evaluation of 4DCT remain lacking. Therefore, this study was designed to evaluate the basic physical characteristics of a respiratory-gated 4DCT helical scanning system (4D-HS) using MATLABR. In this study, the physical characteristics were evaluated by examining the body-axis direction resolution, slice sensitivity profile (SSP), and volume change due to respiratory phase change and comparing multiplanar reconstruction profiles (MPRs) of slit phantoms. These characteristics were compared using normal helical scanning (N-HS). A 31% overestimation was observed in the volume fluctuation of 4D-HS based on the volume of N-HS. Furthermore, SSP with full width at half maximum (FWHM) and modulation transfer function (MTF) showed a similar resolution between 4D-HS and N-HS. The difference in FWHM is considered an offset by the voxel effect. In the MPR comparison, both 4D-HS and N-HS were visually identifiable up to a 0.5-mm slit. 4D-HS is a reconstruction system with excellent temporal resolution. Furthermore, its resolution follows respiratory dynamics and can continuously collect respiratory dynamics components. Our findings suggest the usefulness of 4D-HS in clinical practice.","PeriodicalId":23019,"journal":{"name":"The Showa University Journal of Medical Sciences","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76393608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
