BACKGROUND: We evaluated the preoperative natural growth pattern of craniofacial fibrous dysplasia and postoperative volume changes in patients undergoing shaving procedures. METHODS: Thirty-three patients who underwent serial computed tomography (CT) preoperatively and/or postoperatively were identified. The natural tumor growth rate was assessed using preoperative CT scans. The postoperative tumor regrowth rates and relevant variables were analyzed. RESULTS: The preoperative tumor growth rates

A matched cohort analysis demonstrated that ADM usage is not associated with an increased risk of complications, including skin flap complications, seroma, and infection. Our result suggests that ADM can be safely used in immediate expander-implant breast reconstruction when necessary.

OBJECTIVE: The purpose of the present study was to compare inter-fragmentary compression pressures after fixation of a simulated type II odontoid fracture with the headless compression Herbert screw and a half threaded cannulated lag screw. METHODS: We compared inter-fragmentary compression pressures between 40- and 45-mm long 4.5-mm Herbert screws (n=8 and n=9, respectively) and 40- and 45-mm long 4.0-mm cannulated lag screws (n=7 and n=10, respectively) after insertion into rigid polyurethane

BACKGROUND: First-line antihypertensive drugs include calcium channel blockers, angiotensin converting enzyme inhibitors, angiotensin receptor blockers, and diuretics. In this study, we compared the effects of antihypertensive drugs on the survival of perforator flaps in a rat model. MATERIALS AND METHODS: Fifty normotensive rats were randomly divided into five groups, with 10 rats in each group. Four different antihypertensive drugs were given via oral gavage for 7 days: group I: 1.5 mg/kg amlo

BACKGROUND: Identification of a subgroup of patients with severe postoperative pain is important for adequate pain management for enhanced, fast recovery after deep inferior epigastric artery perforator (DIEP) flap breast reconstruction. The purpose of this study was to identify factors influencing postoperative abdominal pain in patients undergoing DIEP flap breast reconstruction. METHODS: Consecutive patients who underwent unilateral breast reconstruction using DIEP free flaps from October 201

BACKGROUND: Complications after 2-stage tissue expander/implant breast reconstruction have been studied as outcomes of a single procedure. We separately evaluated complications after the second stage and assessed factors associated with the outcomes of the second stage of breast reconstruction. METHODS: Patients who underwent immediate 2-stage breast reconstruction between February 2010 and April 2017 were retrospectively reviewed. Patient demographics, surgical factors of the first stage of bre

Immediate direct-to-implant breast reconstruction after nipple-sparing mastectomy using pure hemi-periareolar incision can be safely performed using indocyanine green angiographic evaluation on the mastectomy skin flap.

Background and Objectives: Patients undergoing mastectomy and implant-based breast reconstruction have significant acute postsurgical pain. The purpose of this study was to examine the efficacy of intercostal nerve blocks (ICNBs) for reducing pain after direct-to-implant (DTI) breast reconstruction. Materials and Methods: Between January 2019 and March 2020, patients who underwent immediate DTI breast reconstruction were included in this study. The patients were divided into the ICNB or control

Background: This study quantitatively assessed perfusion of the deep inferior epigastric artery perforator (DIEP) flap according to vertical location and vertical spacing of perforators during DIEP flap breast reconstruction. Methods: In 67 patients who underwent unilateral DIEP flap breast reconstruction between November 2018 and August 2021, flap perfusion was intraoperatively assessed using indocyanine green angiography. Perforators located at or above the umbilicus were defined as vertical z

Hypoparathyroidism after thyroidectomy occurs as a result of devascularization or unintentional resection of the parathyroid glands. To preserve parathyroid glands, surgeons have to know well about their embryology and anatomy. The parathyroid glands vary in number, size, shape, and color. Because of more variable migration path in the neck, the inferior parathyroid glands are more widely distributed than the superior glands. The upper parathyroid glands are dorsal and the lower parathyroid glan
