CT-Based Measurements of Facial Parameters of Healthy Children and Adolescents in Thailand.

BACKGROUND AND PURPOSE: Facial parameters are used for evaluating normal growth patterns, diagnosing patients with craniofacial abnormalities, and planning surgical procedures. However, these parameters vary by ethnicity and race. This study aims to describe soft-tissue and bony facial parameters based on CT of healthy pediatric and adolescent patients in Thailand. MATERIALS AND METHODS: CT imaging of the brain, orbit, facial bones, and neck was performed at Maharaj Nakorn Chiangmai Hospital, in patients from birth to 19 years old. Patients with known syndromic disease, craniofacial syndrome, facial trauma and/or infection, and previous surgery that deformed the study area were excluded. The key points of measurement were soft-tissue intercanthal, bony interorbital, and bony lateral orbital distances. RESULTS: There were 932 patients: 554 males (59.4%) and 378 females (40.6%). Facial parameters rapidly increased in the first 2 years of life. Significant differences in these parameters between the males and females were found at the age of ≥15 years. However, ratios of the interorbital to the lateral orbital distance were generally consistent among age groups in both sexes, at 0.25. CONCLUSIONS: This study, in Thailand, provides detailed age- and sex-specific normative data of the craniofacial measurements in children and adolescences based on CT imaging. These data can be used for evaluating individual patients with craniofacial abnormalities as well as determining the treatment in Thai and Asian populations, in whom craniofacial abnormalities, for example, frontoethmoidal encephalomeningocele, are common.

The development and application of diabetic foot protocol in Chiang Mai University Hospital with an aim to reduce lower extremity amputation in Thai population: a preliminary communication.

Lower extremity amputation is a frequent complication of diabetes, and the authors' region did not have effective strategies to minimize it. From August 2005 to July 2006, a diabetic foot protocol (DFP) for out-patient management based on a multidisciplinary team approach was tried at the local teaching hospital. There are devices to reduce pressure and educate. After healing, there are custom fabricated orthoses and footwear, and monitoring of progressive ambulation. This report compares the amputation rate in patients receiving DFP care from August 2005 to July 2006 with those who had standard care from August 2003 to July 2005. Sixty-one and 110 diabetic foot ulcer patients received DFP and standard foot care, respectively. Their sex distribution and mean age were similar. The incidence of major amputations in the DFP and standard care groups was 3.3% and 13.6%, respectively (P = .03). The incidence of minor amputations in the DFP and standard care groups was 3.4% and 15.8%, respectively (P = .02). DFP was associated with improved diabetic foot care outcomes. It may be used by clinical teams with a view to improve outcomes for patients with diabetes.
