Influence of the Number of Revision Surgeries and Nasal Symmetry After Final Rhinoplasty for Patients With Cleft Lip.

The effects of operative intervention on vertical nasal growth in patients with unilateral cleft lips (CLs) are well described. However, the factors influencing nasal symmetry have not been sufficiently evaluated. Therefore, this study aimed to study the factors that cause difficulties in obtaining nasal symmetry postoperatively in patients with CLs.

The role of surgeon's learning on the outcomes of alveolar bone graft for cleft repair.

Background And Purpose: Teaching cleft repair in the operating room may not sufficiently prepare craniofacial residents to perform the procedure self-reliantly. This study aimed to assess the influence of surgeons' experience level on the operative time and graft survival ratio after alveolar bone grafts for cleft repair.

Subjects And Methods: This was a retrospective review of 100 consecutive alveolar bone graft patients treated for unilateral alveolar cleft by one craniofacial surgeon between 2012 and 2019.

Symmetrical peripheral gangrene caused by septic shock.

We report three cases of symmetrical peripheral gangrene (SPG) caused by septic shock. Most of sepsis survivors with SPG require amputation of the affected extremities. To preserve the length of the thumb and fingers, we performed surgical amputation and used flaps to cover the amputated peripheral extremities.

Nasal tip surgery for cleft nose in Asians.

"Collapsed nasal tip," one of the most characteristic features of cleft lip nose, resembles the effect of pushing the nose tip with a finger and is especially noticeable among Asians. The authors examined a rhinoplasty technique for improving collapsed nasal tip. Using an intercartilaginous incision, the distal nasal framework, including the alar cartilages, and the caudal septum were widely exposed.

Evaluation of bone volume after secondary bone grafting in unilateral alveolar cleft using computer-aided engineering.

The purpose of this study was to evaluate the initial defect and the outcome of bone grafts for unilateral alveolar cleft. To determine the absorption of the bone graft in patients with unilateral cleft, computer-aided engineering (CAE) with multi-detector row computed tomography (MDCT) was used. MDCT scans of 29 patients were taken immediately preoperatively and at 1 month and 6 months postoperatively.

The inverted Batman incision: a new incision in transcolumellar incision for open rhinoplasty.

Columellar and nostril shapes often present irregularity after transcolumellar incision for open rhinoplasty, because of the contracture of the incised wound. The present study introduces a new technique to prevent this complication, and verifies its efficacy in improving cosmetic appearance. In our new method, a zig-zag incision with three small triangular flaps is made on the columella and in the pericolumellar regions of the bilateral nostril rims.

Involvement of the sphenosquamosal suture for unilateral coronal synostosis.

The etiology of the clinical entity commonly known as unilateral coronal synostosis is often described as the unilateral fusion of the coronal ring. However, recent theories have poorly explained the basis of the deformities associated with unilateral coronal synostosis. We retrospectively analyzed computed tomographic data sets from 18 patients who presented with unilateral coronal synostosis and arrived at our hospital between 1985 and 2010.

Classification of congenital midline upper lip sinuses: a case report and review of the literature.

Background: We recently encountered a case of a midline upper lip sinus, one of the rarest congenital lip sinuses. Several embryological hypotheses have been proposed regarding the etiology of this rare disease, but it remains obscure.

Methods: We reviewed all cases of upper lip sinus reported in the English language through 2011, and classified them into three types according to accompanying anomalies and the site of the fistula.

The boomerang osteotomy -- a new method of reduction malarplasty.

Background: To achieve optimal outcomes in reduction malarplasty, it is important to preserve the natural curvature of the cheek while reducing the zygoma prominence and the width of the midface. The present article introduces an effective technique that aims to achieve these purposes.

Methods: Through an intraoral approach, boomerang-shaped bone incision lines are marked on the anterior aspect of the zygomatico-maxillary junction.

Anthropometric evaluation of bilateral cleft lip nose with cone beam computed tomography in early childhood: Estimation of nasal tip collapse.

Background: Nasal tip features of cleft lip nose cannot be defined well using conventional measurement methods. Therefore, we developed a new method in which vertical nasal tip (the pronasale) position is evaluated based on the Frankfurt-Horizontal plane. This measurement was applied to bilateral cleft lip patients in early childhood.

Effective scoring of scapha prevents helix irregularity in prominent ear correction - a biomechanical study.

Background: As the antihelix is created in the operation for prominent ear, the helix often presents irregularities. This biomechanical study aims to elucidate effective techniques to prevent these irregularities.

Methods: Finite element models were produced simulating 10 prominent ears.

An anatomical study on the position of the summit of the zygoma: theoretical bases for reduction malarplasty.

Background: To achieve optimal outcomes in reduction malarplasty, the area of zygoma from which volume should be reduced must be accurately identified. This anatomical study aims to evaluate the location of the zygoma region that contributes most to the protrusion of the cheek.

Methods: The morphology of the zygoma was studied on 121 Japanese adults (73 men and 48 women).

Biomechanical analysis of the effect of intracranial pressure on the orbital distances in trigonocephaly.

Objective: This biomechanical study aims to elucidate differences in how skulls with trigonocephaly, normal skulls, and postoperative trigonocephalic skulls respond to intracranial pressure and how this affects the orbital distances.

Materials And Methods: For 10 patients with trigonocephaly (8.2 ± 4.

Reconstruction of the scalp with a calvarial defect.

Purpose: To review our clinical cases and devise a protocol for selecting the best operative methods to reconstruct the scalp with a calvarial defect.

Methods: We reviewed the original disease, the areas and depths of the scalp and calvarial defects, the methods of reconstruction, and complications in 20 patients.

Results: The defect was caused by secondary cranial infection following decompressive craniectomy for intracranial hemorrhage (ICH) in 11 patients; extensive removal of the scalp and calvaria for resection of a malignant tumor in 6 patients; and by secondary cranial infection following removal of a malignant tumor in 3 patients.

New classification scheme of proboscis lateralis based on a review of 50 cases.

Background: Among congenital nasal deformities, proboscis lateralis is one of the rarest. Boo-Chai classified proboscis lateralis into four groups. Recently, we encountered a new case of proboscis lateralis with median cleft lip.

Dynamic effects of the Nuss procedure on the spine in asymmetric pectus excavatum.

Objective: This study aimed to elucidate dynamic effects of the Nuss procedure on the spine in the treatment of patients with pectus excavatum with asymmetric thoraces.

Methods: Twenty-five patients with pectus excavatum who underwent the Nuss procedure were categorized into 4 groups by preoperative morphology of the spine and thoracic asymmetry. In group 1 (n = 8), the right side of the thorax was concave and the spine bowed to the right.

Palatoplasty for bilateral oblique cleft of the soft palate accompanied by Tessier number 5·7 cleft.

Craniofacial cleft is a rare congenital deformity in which there are fissures of a facial structure classified by Tessier. A palatoplasty to reconstruct the muscle sling and to close the cleft of the velum was performed. Acceptable postoperative appearance of the velum was seen after 6 months.

Experimental evaluation of susceptibility to fractures of the orbital floor in patients with unilateral complete cleft palate.

We set out this study to verify a hypothesis that orbital floor fractures tend to affect wider areas in patients with unilateral complete cleft palate. Using a striking machine, the inferior orbital rims of eight normal skulls (intact skull group) and eight skulls with parts of the maxillas removed to simulate alveolar and palatal clefts (cleft skull group) were impacted. The fractured areas were compared.

A rare case of proboscis lateralis with median cleft lip.

A very rare case of proboscis lateralis is reported. This case is different from previously reported cases due to proboscis lateralis, single nostril, loss of columella, and median cleft lip without holoprosencephaly. In addition, this is considered the first surviving individual with proboscis lateralis accompanied by median cleft lip.

Double-bar application decreases postoperative pain after the Nuss procedure.

Objective: This biomechanical study aims to elucidate whether additional bar application increases postoperative pain after the Nuss procedure for pectus excavatum.

Methods: Clinical evaluation: The intensity of postoperative pain was compared between patients for whom a single-bar was used (single-bar group: n = 14) and those for whom double bars (double-bar group: n = 10) were used to correct the thoracic deformity. The evaluation was performed by referring to the frequency with which local anesthetics were self-injected in a patient-controlled anesthetic system and how many days were needed for the patients to resume ambulation.
