Objective To assess the differences in scar outcomes between modified rotation-advancement techniques proposed by Drs. Mohler and Noordhoff, designed to address issues such as inadequate vertical lip length and scarring on the upper third of the lip in the original rotation-advancement technique. Design Retrospective single-surgeon (RD) study. Pa...

Objective: To appraise the degree of intraoperative palatal lengthening with the modified Furlow small double-opposing Z-plasty (sDOZ). Design: Retrospective single-surgeon (R.D.) study. Patients: Nonsyndromic children (n = 167) with Veau types I to IV cleft palates who underwent primary sDOZ palatoplasty. Interventions: Intraoperative measu...

Three-dimensional (3D) planning of orthognathic surgery (OGS) improves the treatment of facial asymmetry and malocclusion, but no consensus exists among clinicians regarding technical details. This study verified the consistency of authors’ workflow and strategies between 3D planning and surgical execution for facial asymmetry. This retrospective s...

Background: No consensus exists regarding the timing or technique of rhinoplasty for correction of the unilateral cleft lip nose deformity, with few studies examining the long-term effects of a single technique. This study appraised the long-term outcomes of primary rhinoplasty using the Tajima technique for overcorrection in a cohort of patients...

Objective An inspiring early result with no oronasal fistula formation was recently described for a modified medial incision small double-opposing Z-plasty (MIsDOZ) for treating Veau type I cleft palate. This study describes an early single-surgeon experience in applying this newly proposed surgical approach. Design Retrospective single-surgeon st...

From April 2020, genetic testing for BRCA mutations for diagnosing hereditary breast and ovarian cancer (HBOC) in breast cancer patients, risk-reducing mastectomy, and risk-reducing salpingo-oophorectomy in BRCA mutation carriers began to be covered by the National Health Insurance in Japan, so that medical treatment of HBOC has reached a turning p...

Surgeons-in-training learning how to perform cleft surgery should not only acquire a broad repertoire of technical details but also master the proper execution of techniques based on the modern principles of bilateral cleft lip repair with synchronous reconstruction of cleft nose deformity. This article describes a bilateral complete cleft lip repa...

Background: No consensus exists about the safest position for performing the osseous genioplasty, with 5 to 6 mm below the mental foramen being the most frequently recommended position. This study intends to generate a safe distance guide to minimize the risk of inferior alveolar nerve injury during osteotomy. Methods: Pretreatment cone-beam com...

Background Primary reconstruction of complete bilateral cleft lip and palate (BCLP) with protruding premaxilla in one-stage surgery is challenging because of the tension on muscle repair. Such patients are also common in the developing countries. For this condition, we have applied intraoperative “rapid premaxillary molding (RPM)” technique and obt...

Background: No consensus exists on the selection of procedures for the treatment of submucous cleft palate, with scarce reports on long-term outcomes from single-surgeon experience. This study assessed the outcomes of using extended indication criteria of Furlow palatoplasty as the first-line procedure for the management of submucous-cleft-palate-...

Since the original description of Millard rotation advancement principle for cleft lip repair, many important contributions have subsequently been described by other surgeons worldwide. However, the reconstruction of the nasal floor and intraoral lining has received less attention over time. This article demonstrates a modified unilateral complete...

Nasolabial features of infants with unilateral cleft lip (UCL) are different when they are under general anesthesia for lip repair compared to when they are awake. This study aimed to investigate changes in the incisional design of cheiloplasty according to patient position and anesthesia: upright and awake versus supine and under general anesthesi...

Background It is debatable whether rhinoplasty is necessary during a primary operation for cleft lip. However, many surgeons believe that rhinoplasty should be performed simultaneously for severe deformities. We investigated whether alveolar cleft severity is involved in nasal deformity. Methods Forty-three patients were assessed for alveolar clef...

Background Facial soft tissue anthropometric values change according to a patient’s body position. We compared the facial soft tissue shape between the upright and the supine operative positions in infants with bilateral cleft lip. Methods Twenty-five infants with bilateral cleft lip were photographed in two different positions. Twenty-three anthr...

The usefulness of three-dimensional (3D) stereophotogrammetry for treating cleft lip (CL) has been well documented. However, there are only a few reliable anthropometric analyses in infants with CL because at this age they cannot assume a resting facial position. Since 2014, we have used a handheld 3D imaging system in the operating room to obtain...

Objectives: Conventional 2-stage expander-implant breast reconstruction is frequently performed. However, direct to implant reconstruction should be considered if indicated and if circumstances allow. One difficulty in breast reconstruction postmastectomy is selection of the appropriate implant size prior to surgery. The ability to estimate implan...

Background: The most important element during breast reconstruction preoperative planning is determining the new position and shape of the breast. A youthful breast with no signs of ptosis may not necessarily be the ideal breast for women of all ages. However, indicators have not been established on how breasts should be positioned depending on ag...

Context: During humanitarian cleft care mission in developing countries, a considerable noncompliance of the patient remains evident despite the provided medical support. According to the literature, social background and beliefs are some of the factors that hamper cleft management in these areas. Aims: In this study, we investigated on these impai...

In recent years, various adhesion molecules have been discovered. Very late antigen-4 (VLA-4), an adhesion molecule belonging to the integrin family, plays an important role in lymphocyte migration and infiltration into sites of inflammation. In the present study, we investigated whether administration of anti-VLA-4 monoclonal antibody (mAb) reduce...

Presurgical orthodontic treatment and gingivoperiosteoplasty for the repair of cleft lip yields good morphological results for the lip and nose. In the authors' method, the width of the alveolar cleft was reduced by an orthodontist before cheiloplasty by using the nasoalveolar molding technique. After the primary cheiloplasty, the anterior hard pal...

Background: Many large lipomas are removed under general anesthesia, because more local anesthesia than is safe to inject may be required for complete excision of such large tumors. Methods: The authors performed total excision using tumescent local anesthesia in an outpatient clinic for 23 patients with solitary large lipomas. Results: The lo...

Purpose: Cleft lip repair is performed in the supine position, tilting the head back under general anesthesia. However, postoperative results are evaluated in the upright position while patients are awake. The purpose of this study was to anthropometrically assess whether nasolabial features of infants with unilateral cleft lip are influenced by p...

Abstract Static suspension using fascia lata graft is used as a reconstructive procedure against drooping of the mouth corner for treating longstanding facial paralysis. Although it achieves symmetry at rest, movement of the mouth corner at mouth opening is restricted to some extent because it is fixed with fascia lata to the immovable temporal fas...
