BackgroundThe nasal septal cartilage is often used as a donor graft in rhinoplasty operations but can vary widely in size across the patient population. As such, preoperative estimation of the cartilaginous area is important for patient counseling as well as operating planning. We aim to estimate septal cartilage area by using facial computed tomography (CT) studies.MethodsThe study was performed using facial CT images taken from 200 patients between January 2012 to July 2015. Using the mid-sagittal image, the boundary of cartilaginous septum was delineated from soft tissue using the mean difference in signal intensity (or brightness). The area within this boundary was calculated. The calculated area for septal cartilage was then compared across age groups and sexes.ResultsOverall, the mean area of nasal septal cartilage was 8.18 cm2 with the maximum of 12.42 cm2 and the minimum of 4.89 cm2. The cartilage areas were measured to be larger in men than in women (p<0.05). The area decreased with advancing age (p<0.05).ConclusionMeasuring the size of septal cartilage using brightness difference is more precise and reliable than previously reported methods. This method can be utilized as the standard for prevention of postoperative complication.
BackgroundMost nasal bone fractures are corrected using non-invasive methods. Often, patients are dissatisfied with surgical outcomes following such closed approach. In this study, we compare surgical outcomes following blind closed reduction to that of ultrasound-guided reduction.MethodsA single-institutional prospective study was performed for all nasal fracture patients (n=28) presenting between May 2013 and November 2013. Upon research consent, patients were randomly assigned to either the control group (n=14, blind reduction) or the experimental group (n=14, ultrasound-guided reduction). Surgical outcomes were evaluated using preoperative and 3-month postoperative X-ray images by two independent surgeons. Patient satisfaction was evaluated using a questionnaire survey.ResultsThe experimental group consisted of 4 patients with Plane I fracture and 10 patients with Plane II fracture. The control group consisted of 3 patients with Plane I fracture and 11 patients with Plane II fracture. The mean surgical outcomes score and the mean patient dissatisfaction score were found not to differ between the experimental and the control group in Plane I fracture (p=0.755, 0.578, respectively). In a subgroup analysis consisting of Plane II fractures only, surgeons graded outcomes for ultrasound-guided reduction higher than that for the control group (p=0.007). Likewise, among the Plane II fracture patients, those who underwent ultrasound-guided reduction were less dissatisfied than those who underwent blind reduction (p=0.043).ConclusionOur study result suggests that ultrasound-guided closed reduction is superior to blind closed reduction in those patients with Plane II nasal fractures.
BackgroundLobular keloid appears to be a consequence of hypertrophic inflammation secondary to ear piercings performed under unsterile conditions. We wish to understand the pathogenesis of lobular keloids and report operative outcomes with a literature review.MethodsA retrospective review identified 40 cases of lobular keloids between January, 2005 and December, 2010. Patient records were reviewed for preclinical factors such as presence of inflammation after ear piercing prior to keloid development, surgical management, and histopathologic correlation to recurrence.ResultsThe operation had been performed by surgical core extirpation or simple excision, postoperative lobular compression, and scar ointments. Perivascular infiltration was noted in intra- and extra-keloid tissue in 70% of patients. The postoperative recurrence rate was 10%, and most of the patients satisfied with treatment outcomes.ConclusionHistological perivascular inflammation is a prominent feature of lobular keloids. Proper surgical treatment, adjuvant treatments, and persistent follow-up observation were sufficient in maintaining a relatively low rates of recurrence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
