3-Fr steerable microcatheter system via the upper limb artery in RADPLAT for right maxillary cancer.

BACKGROUND: To evaluate the efficacy of a catheter system using a 3-Fr sheath with a steerable microcatheter through right upper limb artery access for superselective intra-arterial cisplatin infusion and concomitant radiotherapy (RADPLAT) to treat right maxillary sinus squamous cell carcinoma (MS-SCC). MATERIAL AND METHODS: We retrospectively studied 46 sessions in eight patients treated between November 2020 and February 2023 using the catheter system briefly described below. A 3-Fr sheath was inserted into the distal radial, conventional radial, or brachial arteries. A coaxial catheter system with a 2.9-Fr steerable microcatheter and a 1.9-Fr microcatheter was advanced into the brachiocephalic artery. The right common carotid artery was selected by bending the tip of the steerable microcatheter. Coil embolization and intra-arterial cisplatin infusion after selecting each external carotid artery branch were achieved using this catheter system. RESULTS: Cisplatin infusion and coil embolization were successful in all sessions. Arterial occlusion at the sheath insertion sites was found in 29.4% (5/17) of the distal radial arteries and 33.3% (3/9) of the conventional radial arteries. No other major complications were observed during the procedure. CONCLUSION: Using a 3-Fr catheter system with a steerable microcatheter through right upper limb artery access is a feasible method for RADPLAT in treating right MS-SCC.

Surgical results of primary lip repair using the triangular flap method for the treatment of complete unilateral cleft lip and palate: a three-dimensional study in infants to four-year-old children.

OBJECTIVE: To evaluate morphological problems for children with complete unilateral cleft lip and palate (UCLP). DESIGN AND SETTING: A cross-sectional study was performed on 46 patients with complete UCLP at Osaka University Dental Hospital. PATIENTS AND PARTICIPANTS: The method was applied to three groups of children with UCLP (8 4-month-old infants, 18 1.5-year-old children, and 20 4-year-old children). MAIN OUTCOME MEASURES: The three-dimensional coordinates of facial landmarks were extracted automatically from XYZ data sets and from photo images produced by an optical surface scanner. RESULTS: The intercanthal distance, nose width, and mouth width were closer to those of normal children in the older group. Deviation of the columella toward the noncleft side was smaller in the 4-year-old group. The angle of the nasal tip was large in all groups. Asymmetry of the ala was conspicuous at the upper part of the nose in the vertical dimension. Asymmetry of the nostril was observed in the vertical dimension and in the anteroposterior dimension in the 4-year-old group. The angle of the Cupid's bow was obtuse on the noncleft side, and the bottom of the Cupid's bow deviated toward the cleft side. The Cupid's bow was longer on the noncleft side. Protrusion of the vermilion was poor in all groups.

Three-dimensional analysis of facial morphology in normal Japanese children as control data for cleft surgery.

OBJECTIVE: This study presents an analysis of three-dimensional facial forms of normal Japanese children. DESIGN AND SETTING: Cross-sectional data (n = 247) were available from the Ikeda Public Health Center. PATIENTS AND PARTICIPANTS: Three groups of children (ninety-seven 4-month-old infants, fifty-four 1.5-year-old children, and eighty 3.5-year-old children) were analyzed using a three-dimensional anthropometric technique. MAIN OUTCOME MEASURES: Three-dimensional coordinates of facial landmarks were extracted automatically from XYZ data sets and photo images of an optical surface scanner. RESULTS: Only minor gender differences were noted. Lip height was not correlated with other facial dimensions. There was a significant correlation between upper face, nose, and mouth widths. Compared with adults, the upper face width was larger (approximately 70% to 80% of adults) than the middle and lower parts of the face. Width ratios were greater than height and depth ratios. The lip height ratio, however, was larger than the lip width ratio, and the angle of the cupid's bow was more acute in children. The angle of the nose was more obtuse, particularly in the axial plane. CONCLUSIONS: In cleft lip surgery involving young children, there may be no need to consider gender differences. Some characteristic differences exist between children and adults, however, and normal standards for children would be helpful in plastic surgery.
