Authors: Yang Chenjie , Qian Yufen , Chen Zhenqi , Yang Yusheng , Yu Quan 
Published: January 2019

Objectives:
The aim of the study was to explore the effectiveness of the cleft-adjacent teeth moved into the grafted alveolar bone in unilateral cleft lip and palate (UCLP) patients, and to evaluate the alveolar bone support of the teeth.

Methods:
Twenty unilateral cleft lip and palate patients were recruited in this study. The average age was 12 years and 8 months. Periapical radiographs were taken for the cleft-adjacent teeth 3 months after bone grafting (T1) and after teeth moving into the grafted bone (T2), and for the contralateral teeth (T3) when teeth aligned. Alveolar bone support of the moved teeth and the contralateral teeth were measured using the ratio of bone support height to root length. Paired t test was performed for statistical analysis with SPSS17.0 software package.

Results:
All the cleft-adjacent teeth were bodily moved into the grafted area. Average alveolar bone support ratio for the moved teeth was 86.48% (T1), 87.11% (T2), and 90.81% (T3) for the contralateral teeth. There was no statistically significant difference between T1 and T2 (P > 0.05). Although the contralateral teeth had the highest alveolar bone support ratio, significant differences were found between T3 and T2 (P < 0.05).

Conclusions:
Cleft-adjacent teeth could be bodily moved into the grafted bone from the iliac crest in UCLP patients. A successful level of alveolar bone support for the moved teeth was achieved. Moved-in teeth could be functionally loaded and may be benefit to the reduction of the resorption of grafted bone.

Published: January 2019

Abstract
Face proportions are under constant evaluation during prosthetic or surgical diagnostics and treatment. The aim was to evaluate the proportions of the faces of young Polish women as compared with other ethnic groups.

Materials and methods:
The evaluation included 60 photographs of the faces of women, average age 17.9 years. En face images were made with the camera lens situated at the same distance from the photographed subjects. Using Adobe Photoshop software, midsaggital and even anthropometric points were determined in the photographs and then the distance between these points was measured. Four relationships between vertical measurements, 3 between horizontal measurements, and 4 proportions between vertical and horizontal measurements were calculated. The results were evaluated in comparison with the golden ratio (1.618) and the measurements performed for native Americans and Latin American beauty contests winners described in the relevant literature.

Results:
The result for the average vertical face proportion value of the examined women was close to the golden ratio (GR) and amounted to 1.592 for the proportions between nasion-stomion and stomion-gnation (98% of GR) and 1.372 for nasion-subnasale and subnasale-gnation (85% of GR).
Average measurement results for young Polish women's faces were not statistically significantly different for 6 out of 11 relationships under evaluation as compared with the population of native American females and only 2 face proportions were the same as for beauty contests winners from Latin America.

Conclusion:
Face proportions of young Polish women were different from those of the females living in the American continent.

Published: January 2019

Abstract
Despite the popularity of lipofilling procedures in recent years, the presence of older habits still in fat graft harvesting and processing seems to be the biggest obstacle to the final better outcome of fat grafting. Our study is aimed to highlight some strategies what should be done in fat grafting in the shadow of evidence-based medicine and patient-reported outcomes which might be of interest to the clinicians. Between 2015 and 2017, 14 patients were included who underwent facial micro-autologous fat transplantation with platelet-rich plasma injection. The outcome was determined by the difference in presurgery and postsurgery FACE-Q modules, which were designed as patient-reported outcome instrument to evaluate the unique outcomes of patients undergoing facial cosmetic procedures. Surveys conducted were modules of satisfaction with facial appearance, satisfaction with cheeks, satisfaction with skin, psychological function, social function, aging appearance appraisal, and satisfaction with the outcome. All patients were followed up minimum 9 months. No major complications were recorded. The patient-reported FACE-Q satisfaction and FACE-Q quality-of-life presurgery and postsurgery results showed statistically significant improvement (<0.001). Overall satisfaction with the outcome was 87.6 ± 16.8 (range 55–100). A combination of platelet-rich plasma and micro-fat grafting with soft harvesting and processing could be seen a good surgical technique to restore volume and enhance skin quality in facial soft tissue augmentation. The authors believe that with minimum detrimental effect on fat grafting while harvesting, processing, and with the addition of platelet-rich plasma while applying may increase the surgeon's and patient's satisfaction with the outcome.
A Novel Approach for Horizontal Augmentation of Posterior Maxilla Using Ridge Split Technique
Authors: Karan Nazife Begüm , Akinci Hüseyin Ozan 
Published: January 2019

Abstract
Over the years, there have been a series of innovative approaches to the alveolar bone augmentation techniques. These have led to the modifications of the existing methods and the establishment of more efficient ways to obtain sufficient bone mass that is necessary for the implant procedure. The aim of this paper is to propose a novel augmentation technique, and to investigate its efficacy, particularly during the healing process of the maxillary alveolar bone prior to the implant treatment. During the application of the proposed methodology, first, the ridge-split technique was applied to the posterior maxilla. Then, a horizontal augmentation procedure was performed with an autogenous bone graft. Implants were placed at the second month of the surgery. Prosthetic rehabilitation was completed after the osseointegration of the implants. The technique was compared with the ridge-split method with simultaneous implant placement in 14 patients. The groups were divided into 2, the control group and the experimental group, each containing 7 patients. The aimed success criteria for the status of the endosteal implants were fulfilled and there were not any complications observed in the second year of follow-up.
The basic practical innovation offered by the proposed surgical technique is to achieve the required horizontal dimension and to change the quality of the bone conveniently. The press-fit insertion leads to multipoint contact healing of the transported bone and the use of cortical block bone in posterior maxilla, led to a significantly advantageous higher stability level for both the placement and the survival of the implants.
Effect of Platelet-Rich Fibrin and Bone Morphogenetic Protein on Dental Implant Stability
Authors: Alhussaini Ali H. Abbas 
Published: January 2019

Abstract
Recombinant human bone morphogenetic protein-2 (rhBMP-2) and platelet-rich fibrin (PRF) bioactive materials have been used to enhance healing and improve dental implant stability. This study aimed to compare the effect of rhBMP-2 and PRF bioactive materials on dental implant stability at different intervals and to evaluate the correlation of implant length and diameter with implant stability.
Two bioactive materials were compared to evaluate their effect on dental implant stability. A total of 32 patients (102 dental implants) were divided into 3 groups: 24 dental implants with bone morphogenetic protein (BMP), 27 dental implants with PRF, and 51 dental implants without BMP or PRF (control group). Data were statistically analyzed to determine the bioactive material with the best effect on implant stability.
Implant stability did not significantly differ between the groups immediately after implant insertion (first reading; P > 0.05). The implant stability of the rhBMP-2 group was significantly better than those of the PRF and control groups 6 weeks after implant insertion (second reading; P = 0.001). After 12 weeks, the effect of rhBMP-2 on implant stability was highly significant and better than that of the other groups (third reading; P < 0.001).
Dental implants coated with BMP have a better effect on stability than those with PRF alone and those without PRF or BMP.

Published: January 2019

Objective:
Nonsurgical and surgical options are available for transgender vocal feminization. This systematic review explores the efficacy of feminizing voice therapy and phonosurgery.

Methods:
A systematic review was performed using PubMed, Cinahl Plus, Ovid SP, Web of Science, Science Direct, and Google Scholar with terms related to transgender phonosurgery and voice therapy. Included studies were outcomes-based vocal feminization interventions for transgender women. Data were collected on pre- and postintervention fundamental frequency (F0), externally measured vocal femininity, patient satisfaction, and complications.

Results:
Two hundred twelve studies were identified and 20 met inclusion criteria. Postintervention patient satisfaction was approximately 80% to 85% for voice therapy, endoscopic shortening, and cricothyroid approximation. Complications were reported for each phonosurgery technique, most commonly decreased mean phonation time and loudness. Of the 20 studies, 17 were used for meta-analysis of F0 change. F0 increased by 31 Hz with voice therapy alone, 26 Hz with laser reduction glottoplasty, 39 Hz with cricothyroid approximation, and 72 Hz with endoscopic shortening.

Conclusion:
The literature supports both voice therapy and phonosurgery, depending on a patient's magnitude of desired pitch change and tolerance for cost and potential complications. Most will likely benefit from voice therapy, as it is highly satisfactory, raises vocal pitch, and is noninvasive. However, endoscopic shortening is also highly satisfactory and provides the greatest absolute increase in vocal pitch. If surgery is chosen, postoperative voice therapy may additionally increase F0, stabilize the voice, and create a more female timbre. However, further studies will be necessary to provide definitive clinical recommendations.

Published: January 2019

Background:
Facial fractures may result in a significant time away from competition for professional rugby players. An understanding of the return-to-play times is an integral part of clinical decision making when treating professional athletes. A period of 8 to 12 weeks has been conventionally recommended for returning to collision sports after facial fractures. The conventional time to return to sports of 8 to 12 weeks is usually too long for professional players. However, the time of return to play after such facial fractures in elite athletes has not been well described.

Purpose:
To investigate the return to play after facial fractures in professional rugby players with an accelerated rehabilitation protocol.

Methods:
Ten professional rugby players with facial fractures were identified and analyzed. The authors investigated the number of days required to return to training and full-contact play according to the trauma type. The authors also determined the presence or absence of refractures and sequelae.

Results:
The average age of the patients was 26.9 years. Medial orbital wall fractures were the most represented pattern, followed by orbital floor fractures and zygomatic arch fractures. The players returned to jogging after 9.9 days, to sports-specific training after a mean of 10.8 days, and to full-contact training after 18.3 days. There were no cases of refractures and sequelae.

Conclusion:
Players were able to return to their regular rugby activities, earlier than the time commonly allowed to return to full activity.
Fronto-Orbital Advancement: Description of Surgical Technique to Complement the Procedural Cognition Simulation in the Craniofacial Interactive Virtual Assistant-Professional Edition
Authors: Staffenberg David A. , Diaz-Siso J. Rodrigo , Flores Roberto L. 
Published: January 2019

Abstract
The surgical treatment of nonsyndromic craniosynostosis is one of the most common procedures performed by craniofacial surgeons. However, for residents and fellows, the high degree of difficulty and complex anatomy may result in slow progress along a steep learning curve. This is particularly important in the context of contemporary academic practice, where work-hour limits and other factors restrict operative exposure and opportunities for trainees to learn. These issues have prompted the development of surgical simulation modalities that, while prevalent in other surgical specialties, have not been fully adopted in reconstructive surgery.
Among these resources is the Craniofacial Interactive Virtual Assistant - Professional Edition (CIVA-Pro), a procedural cognition simulator that is free of charge. By integrating 3-dimensional virtual animation, voice over, and high-definition intraoperative video, CIVA-Pro describes cardinal craniofacial surgery procedures in an engaging platform. In this study, a detailed, step-by-step description of the fronto-orbital advancement surgical technique to complement the corresponding CIVA-Pro module was presented. This synergistic combination of multimedia educational resources provides a unique didactic option for current trainees to prepare for surgery.

Published: January 2019

Abstract
Polymethyl methacrylate (PMMA), an easily moldable and economical synthetic resin, has been used since the 1940s. In addition, PMMA has good mechanical properties and is one of the most biocompatible alloplastic materials currently available. The PMMA can serve as a spacer and as a delivery vehicle for antibiotics. Prior studies have indicated that no significant differences in infection rates exist between autologous and acrylic cranioplasty. Although inexpensive, the free-hand cranioplasty technique often yields unsatisfactory cosmetic results. In the present study, the application of a recently developed, economic modality for the perioperative application, and molding of PMMA to ensure a precise fit in 16 patients using computer-aided design, computer-aided manufacturing, and rapid prototyping was described.
The mean defect size was 102.0 ± 26.4 cm2. The mean volume of PMMA required to perform the cranioplasty procedure was 51 mL. The cost of PMMA was approximately 6 Euro (€) per mL. The costs of fabricating the implants varied from 119.8 € to 1632.0 € with a mean of 326.4 € ± 371.6. None of the implants required removal during the follow-up period.
In Vivo Degradation of Forged-Unsintered Hydroxyapatite and Poly-l-lactide Mesh Used for Orbital Reconstruction
Authors: Hwang Kun 
Published: January 2019

Abstract
The aim of this study was to assess compositional changes in a forged-unsintered hydroxyapatite and poly-l-lactide (uHA/PLLA) mesh at 651 days after insertion into human body.
A 35-year-old female patient had left tripod fracture, orbital medial wall and floor fracture, and superficial lateral palpebral ligament rupture. On the 9th posttrauma day, the tripod fracture was reduced and fixed with plates, and the orbital wall and floor were reconstructed with a resorbable mesh. The floor and medial wall were reconstructed with a trimmed mesh made of uHA/PLLA (Osterotrans-MX; Takiron Co, Umeda, Japan). On postoperative day 620, she complained of enophthalmos of left eye (right eye, 18 mm; left eye, 16 mm). Secondary reconstruction of the orbital floor was performed with an iliac bone graft 651 days after insertion. During the secondary operation, the uHA/PLLA mesh that had been previously inserted was removed. The mesh was removed and analyzed using gel permeation chromatography (GPC) and Fourier transform infrared spectroscopy (FTIR).
The GPC revealed that the weight average molecular weight (Mw) decreased from 542,000 to 83,300 Da and the number average molecular weight (Mn) decreased from 124,000 to 20,200 Da in the specimen from the operation. In the postinsertion FTIR spectrum, weak 1648.6 and 1656.1/cm peaks newly appeared. The strong 1038/cm peak of the initial specimen changed slightly into a less strong 1041.8/cm peak.
In conclusion, the reduced Mw and Mn in the postinsertion specimen suggest that uHA/PLLA has one of the favorable degradation properties. The newly appeared bands are thought to be carbon-carbon double bonds of alkenes.

Published: January 2019

Abstract
The authors sought to compare hospital utilization and complications in patients undergoing pharyngeal flap (PF) or sphincter pharyngoplasty (SP) for velopharyngeal insufficiency (VPI). A retrospective analysis of the 2014 and 2015 American College of Surgeons National Surgical Quality Improvement Project-Pediatrics (ACS NSQIP-P) was performed. Current procedural terminology codes were used to identify children undergoing PF (42225, 42226) and SP (42950) for VPI (International Classification of Diseases version 9: 478.29, 528.9, or 750.29). Four hundred forty-six patients were treated for VPI with either PF (n = 250) or SP (n = 196). The groups were demographically similar in age, gender, race, and preoperative comorbidity. Pharyngeal flap was performed less often as an outpatient procedure than SP (96/250 [38.4%] vs 130/196 [66.3%], P < 0.0001) and had a longer total length of hospital stay (mean 1.76 ± 1.29 vs 0.98 ± 0.91 days, P < 0.0001). No difference in total complications (10/250 [4.0%] vs 3/196 [1.5%], P = 0.124) was identified. The reduction in hospital resource utilization (fewer admissions, shorter length of stay) is notable. No difference in complications was identified between the 2 procedures.
Endoscopically Assisted Middle Cranial Fossa Reconstruction Following Traumatic Intracranial Intrusion of the Mandibular Condyle
Authors: Liau Isaac , Sambrook Paul , Cheng Andrew 
Published: January 2019

Abstract
Traumatic intracranial intrusions of the mandibular condyle are a rare injury pattern that carries significant morbid outcomes due to potential for neurological, otological, temporomandibular joint damage, or joint ankylosis. Treatment modalities involve either closed reduction, open approaches via transcranial or subtemporal approaches, or delayed total joint replacement. This paper presents a clinical report of a traumatic intracranial intrusion of the mandibular condyle treated with an endoscopically assisted preauricular approach to reconstruct the middle cranial fossa and temporomandibular articular disc. Endoscopically assisted techniques allow for minimally invasive and less morbid surgical interventions to this pathology, with greater precision than closed reduction techniques.

Published: January 2019

Abstract
Orbital asymmetry in unicoronal synostosis impacts craniofacial appearance and can potentiate functional visual disturbances, such as strabismus. Surgical treatment aims to normalize overall cranial morphology, including that of the orbits. The purpose of this study was to compare postoperative changes in orbital asymmetry following 2 common procedures.
Preoperative and 1-year postoperative computed tomography scans for patients with isolated, nonsyndromic unicoronal synostosis treated from 2007 to 2012, at 2 academic institutions were analyzed. Only patients treated by endoscopic suturectomy and postoperative helmeting or bilateral fronto-orbital advancement were included. Orbital index, depth, and volume asymmetry were determined for each patient both pre- and 1-year postoperatively. Student's t-tests were used to compare pre- and postoperative asymmetries within each treatment group. Regression analyses were used to examine postoperative change in asymmetry between treatment groups.
Scans from 12 patients treated by fronto-orbital advancement and 23 treated by endoscopic suturectomy were analyzed. Differences between synostotic and nonsynostotic orbital index, depth, and volume were statistically significant both pre- and postoperatively. Statistically significant postoperative improvements in asymmetry were observed for orbital index, depth, and volume following suturectomy. Regression analysis indicated that the amount of pre- to postoperative change in all measures of asymmetry did not depend on surgical technique. Residual asymmetry following both procedures was apparent at 1 year postoperatively.
Orbital asymmetry is improved, but not resolved following both fronto-orbital advancement and endoscopic suturectomy. Degree of improvement in symmetry is independent of surgical technique used.
