Authors: Pauwels-Tumiñan Andrés , Lozano-Morales Constanza , López Juan Pablo , Orjuela María Paula 
Published: August 2020

Abstract
Condylar hyperplasia is an alteration in mandibular growth that can cause facial asymmetry and occlusal changes that usually affect the aesthetics and function of patients. To date, condylectomy for its part remains a key part of the treatment. Although there are still controversies regarding the amount of bone to remove and the surgical approach, there are still other concerns, such as finding the benefit in terms of intraoperative safety and postoperative results with different cutting devices, including the use of piezoelectric, which is increasing its use in the maxillofacial field. This is why the main objective of this study is to compare the results found in medical records and databases of condylectomy procedures performed between 2017 and 2019 with different cutting devices.

Authors: Emsen Ilteris Murat 
Published: August 2020

Abstract
Lips are an important unit of the lower face. In the literatures, not so many augmentation methods are seen except the fat graft, filler material, alloplastic prosthesis, fascia grafts. Each one has both advantages and disadvantages. The most valuable method for lip augmentation should be minimally invasive, low cost, and resistant to resorption. The authors are presenting different and novel graft material for lip augmentation. The method has some important advantages such as both long lasting result and no cost, and not any donor area morbidity.

Authors: Xu Kangxin , Lin Yan , Gao Yuan , Wang Yuqun 
Published: August 2020

Aim:To evaluate the implementation of a clinical pathway (CP) and identify clinical factors affecting the CP for cleft lip and palate (CLP) patients.Methods:A specific CP for CLP patients was developed at CLP Medical Center of Stomatological Hospital affiliated to Nanjing Medical University in 2008. The authors reviewed the collected data of 1810 consecutive patients using the CP for repairing cleft lip, cleft palatal, and alveolar cleft. The patients were treated between January 2008 and December 2019. The rate of completion and risk factors affecting dropout from the CP were analyzed.Results:The completion rates of the CP in cleft lip, cleft palate and alveolar cleft patients were 68.3% (n = 345), 82.4% (n = 785) and 76.1% (n = 268), respectively. The overall completion rate was 77.2% (n = 1398). The main reasons for dropping out were pre-operation events (n = 212, 11.7%) and post-operation events (n = 188, 10.4%). Among the factors of dropout of CP, laboratory test abnormalities accounted for the majority of pre- and post-operation events (n = 179, 9.9%). In statistical analysis, the combined abnormities and events associated with operations were significant risk factors affecting the dropout rate from CP.Conclusion:The use of CP for CLP patients was reliable but the completion rate was relatively low because of perioperative events. These results provided some evidence of risk factors which should be considered when modifying the protocol of CP for CLP patients in order to achieve higher completion rate.
Achieving the Optimal Aesthetic Benefit While Correcting Midface Deficiency: Utilizing A High Winged Le Fort I in Cleft and Craniofacial Patients
Authors: Strong Amy L. , Ulma Raquel M. , Duncan Anthony , Vercler Christian J. , Buchman Steven R. 
Published: August 2020

Abstract
Craniofacial anomalies are congenital disorders that affect the cranium and facial bones, with cleft lip and palate being the most common. These anomalies are often associated with abnormal development of pharyngeal arches and can result in the development of class III malocclusion and severe maxillary retrusion. Current treatment includes orthodontic decompensation and Le Fort I osteotomy to correct the maxillomandibular relationship. However, the traditional Le Fort I (LFI) advancement does not fully address the lack of skeletal volume in the midface. The high winged Le Fort I osteotomy (HWLFI) is an excellent surgical option for simultaneous correction of the midface deficiency and malocclusion while restoring optimal esthetic convexity. A retrospective chart review was conducted to include all cleft and craniofacial patients who underwent HWLFI advancement from 2002 to 2018. Patients had a minimum of 12 months of follow-up. Patient data and complications were reviewed. Standardized facial photographs were analyzed for esthetic improvement, occlusion, and beneficial salutary effects on the midface. Forty-three patients met the inclusion criteria. The mean age at surgery was 18.9 years. The mean follow-up was 32 months. Early complications included infection (9.3%) and temporary nerve paresthesia (2.3%). Late complications included infection (6.5%), wound dehiscence (4.3%), and painful hardware (2.3%). One patient (2.3 percent) had clinically significant relapse that required surgery. Postoperatively, patients demonstrated excellent midface projection and correction of the skeletal malocclusion. The HWLFI advancement significantly improves both the malocclusion and esthetic concerns of cleft and craniofacial patients by reestablishing maximal midfacial support. Important advantages of the HWLFI are avoidance of alloplastic implant use and extensive and potentially unstable surgical procedures that increase orbital volume.

Published: August 2020

Abstract
The aims of this study were to determine the sphenoid sinus volume in an Austrian population, evaluate the relationship between volume and different types of pneumatization and investigate possible age-related sphenoid sinus volume degeneration in the elderly. A total of 50 human cadaver including 25 male and 25 female samples (=100 sphenoid sinuses, age range 65–100, mean age 84.52 ± 9.50) were selected to obtain volume and anatomical variants of pneumatization by using sphenoid sinus casts, made of quadrofunctional hydrophilic addition reaction silicone. The mean sphenoid sinus volume was 4.79 ± 2.39 cm3. Males showed statistically significant larger sinus volumes than females (P = 0.048). The volume differed statistically significant for the different types of pneumatization (P < 0.001). The combined type of sphenoid sinus pneumatization presented the largest volume with 7.20 cm3, followed by lateral, clival, sphenoid body, presellar, and conchal sinus type with 5.72, 5.63, 4.25, 2.08, and 0.5 cm3, respectively. No significant correlation between age and sphenoid sinus volume was found (P = 0.707). This study highlights the close relationship between volume and morphology of sphenoid sinus and confirms ethnic variability. Moreover, our data shows no age-related volume degeneration.
VITOM 3D System in Parotid Gland Surgery: Our Experience
Authors: Mincione Antonio , Lepera Davide , Rizzi Lucio 
Published: August 2020

Abstract
In this report, we present our experience with the VITOM 3D system for parotid gland surgery. A retrospective review of 9 consecutive VITOM 3D-assisted parotidectomies was carried out. All of the cases included had benign pathology. Eight of the tumors were in the superficial lobe whereas one case arose in the deep lobe. Superficial parotidectomy type II, according to the ESGS classification, was performed in 5 cases (55.6%): type I–II in 2 cases (22.2%), type I and III in 1 case respectively (11.1%). The postoperative period was uneventful for all of the patients, and no cases of postoperative temporary or definite facial nerve palsy or other complications were reported. The mean operating time was 145 minutes (range 135–165 minutes). Asthenopia never occurred, and there were no cases in which the first surgeon, the assistants, or the nurses needed to interrupt the 3D vision. VITOM 3D has been demonstrated to be safe and effective for parotid gland surgery. The main advantages of VITOM 3D are improved visualization, ergonomics, versatility, training, and education. The drawbacks are related to asthenopia and the learning curve, even though, in our experience, the impact of these factors is minimal.

Authors: Enomoto Akifumi , Kinoshita Yuko , Matsunaga Kazuhide , Sukedai Miho , Shimoide Takeshi , Ehara Hiroki , Hamada Suguru 
Published: August 2020

Objectives:
The aim of the present study was to evaluate the functional and esthetic results of marginal mandibulectomy for mandibular cancer using a lateral approach with a simple, straightforward mouth corner incision.

Study Design:
Six mandibular cancer patients (2 men, 4 women; age range: 65–80 years; mean age, 73.1 years; all stage I) were treated using this approach. With this approach, the surgical field was widely exposed, and mandibulectomy was performed with sufficient surgical margins. Intraoperative frozen specimens of remaining tissues showed no malignancy in all cases. In all 6 patients, follow-up imaging assessments were obtained, with no local recurrence after 12 to 78 months.

Results and Conclusions:
An overall functional, physical, and esthetic assessment of oral behavior and oral appearance was made of all patients by the FACT-H&N questionnaire, which showed that functional lip behavior and esthetic lip appearance were not much affected by the present surgical approach, and good quality of life was maintained. Thus, the lateral approach with the mouth corner incision is an effective and useful alternative for the molar part of mandibulectomy.
Soft Tissue Changes After Clockwise Rotation of Maxillo-Mandibular Complex in Class III Patients: Three-Dimensional Stereophotogrammetric Evaluation
Authors: Choi Tae-Hyun , Kim So-Hyun , Yun Pil-Young , Kim Young-Kyun , Lee Nam-Ki 
Published: August 2020

Objectives:
To evaluate the linear, angular, and volumetric changes of soft tissue after clockwise repositioning of the maxillo-mandibular complex in skeletal class III patients using three-dimensional (3D) stereophotogrammetry and to determine the correlation between changes in the skeletal and soft tissue variables.

Methods:
This study included 18 skeletal class III patients who underwent two-jaw surgery; superior impaction and clockwise rotational movement of the maxilla with the rotation center at upper incisors, and setback of the mandible. Lateral cephalograms and 3D photographs taken before and 6 months after surgery were compared.

Results:
After maxillary impaction of anteriorly 1.7 mm and posteriorly 3.1 mm, and mandibular setback of 8.7 mm, the volume of lower lip and chin region decreased significantly by 33.6 cm3 (13% net change, P < 0.001), while paranasal and upper lip region volume increased by 3.2 cm3 (2%) and 7.2 cm3 (4%), respectively.

Conclusion:
The clockwise rotation of maxillo-mandibular complex in class III patients significantly reduced lower lip and chin volume with minimal increase in paranasal and upper lip volumes. 3D stereophotogrammetry can provide quantitative evaluation of facial soft tissue volumetric changes.

Authors: Kelemen Noemi , Mota Ashley , Bains Robert D. , Liddington Mark I. 
Published: August 2020

Background:
Herein, the author report a severe case of large facial mixed germ line tumor associated with neuronal migration disorder, polymicrogyria, and corpus callosum agenesis. This specific association has not been reported as yet.

Method:
A 33-year-old primiparous woman at 38th week, delivered 3820 g male baby, via Cesarian section. Postpartum profuse bleeding was noticed from a large, ulcerative, 7 cm exophytic left facial mass, which was controlled nonoperatively. The treatment included surgical excision and 560 g of large facial tumor. Histology results revealed mixed germ line tumor with grade 3, immature teratoma.

Results:
Four months postoperatively the teratoma recurred in the buccal, tonsillar, and parapharyngeal areas. Fourteen months following the initial surgical excision the patient died from airway obstruction.

Conclusion:
Due to poor initial prognosis further treatment of the facial malignancy was not feasible. However, initial, early postnatal, excisional surgery provided a prolonged and better quality of life for the patient and family.

Authors: Zhou Yicui , Pan Chunchen , Guo Tao , Wang Yinfeng , Zhao Yi , Sun Jingwu 
Published: August 2020

Abstract
Teratomas are germline tumors commonly composed of multiple cell types derived from embryonic germ cell layers. Teratomas in head and neck region are exceptionally rare and present during the neonatal and infantile period. We describe a male adult with a mature teratoma originating from sphenoid body. A 24-year-old male patient presented with left-sided intermitted headache and facial numbness. Radiographic imaging showed a 3 cm × 2.3 cm mass with heterogeneous density in the sphenoid region. The endoscopic sphenoid sinus opening surgery was performed through endonasal transpterygoid approach. The final pathologic diagnosis was confirmed as mature teratoma. The patient has been followed-up for 18 months without recurrence. We suggest endonasal transpterygoid approach could be an effective and safe treatment for patients with mature teratoma in the sphenoid bone.

Published: August 2020

Abstract
Pseudoaneurysm resulting from the external carotid artery or its branches after trauma to the maxillofacial region is unlikely, even more so, in a patient with von Willebrand disease. This study aimed to report a challenging case of pseudoaneurysm of the buccal artery and inferior alveolar artery due to a mandible fracture in a traumatized patient with undiagnosed von Willebrand disease. This reported case was conducted by a multidisciplinary team, covering the departments of maxillofacial surgery, interventional neuroradiology, neurosurgery, and hematology. From a fracture of the lower jaw and the appropriate course of action, bleeding episodes followed until intervention with embolization therapy. To our knowledge, this is the first case reported in the literature of a patient with those conditions.

Published: August 2020

Abstract
In December of 2019, a novel virus known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) produced a cluster of viral pneumonia cases in Wuhan, China. In the United States (US), New York City was particularly devastated, with the volume and acuity of patients placing an unprecedented strain on the hospital system and health care workers. In response to this crisis, USNS Comfort (T-AH 20) was deployed to New York City with a 1100 member medical team to augment local hospitals. Comfort's mission to New York City was dynamic, and required special adaptation to care for both COVID positive and COVID negative patients. Neuroplastic surgery procedures were indicated in both COVID positive and COVID negative patients, and lessons learned with regard to performance of complex surgery in an unfamiliar environment consisted of developing a thorough understanding of ones capabilities, and working with a highly skilled team of Navy surgeons, anesthesiologists, and surgical support staff, in order to provide high quality care in a deployment platform.

Published: August 2020

Background:
Skin color matching is an essential factor in achieving optimal aesthetic outcome in partial facial transplantation. However, there is no published literature evaluating the success of color matching to date. Furthermore, a medical professional's perception of an optimal color match may not necessarily translate to that of the general public. The purpose of our study was to evaluate skin color matching between the donor allograft and recipient native tissue in partial facial transplantations to determine the level of success perceived by the general public and medical professionals.

Methods:
Published photographs of partial face transplant recipients were used to create a survey where recipient native and donor allograft skin samples were juxtaposed. Thirty-three members of the general public and 30 medical professionals were asked to rate skin color match on a scale from “excellent match” to “not a match.”

Results:
Overall, 47% of given ratings were positive, indicating an “excellent” or “good match,” and 53% of ratings were negative, indicating a “poor match” or “lack of match” between the skin sample pairings shown. Of the 19 partial face transplant patients who were rated, 9 patients received >50% positive ratings, and 10 patients received <50% positive ratings. Medical professionals consistently gave more positive ratings, with statistically significant differences in 7 of the 19 rated patients (P < 0.05).

Conclusion:
The results suggest that there is need for improvement in color matching in partial facial transplantation, and that the general public is more critical of skin color matching compared to medical professionals.

Published: August 2020

Abstract
Cerebral fat embolism following facial autologous fat injection is a rare and serious complication. There are limited long-term follow-up data on the motion, cognitive and mental outcomes of surviving patients with cerebral fat embolism following facial autologous fat injection. In this study, the authors reported a patient with a 22-year-old woman with a massive right hemisphere infarction following facial autologous fat injection had normal cognitive function, independent living ability, and social function at 5 years follow-up visit, even though computed tomography showed her entire right cerebral hemisphere had atrophied with softening lesions.
Cleft Lip and Palate Surgery Crowdfunding and Access to Care
Authors: Akiki Ronald K. , Jehle Charles , Crozier Joseph , Woo Albert S. 
Published: August 2020

Abstract
A total of 169 ACPA approved teams treat cleft deformities in the United States. These centers are unevenly distributed, and families may disproportionally pay extra travel costs to consult a multidisciplinary cleft team. Families experiencing hardships are able to create campaigns on GoFundMe to advertise their fundraiser publicly. The authors sought to establish whether a correlation exists between patients asking for support for cleft treatment and their geographic location in the US.
A total of 635 crowdfunding campaigns for cleft lip and/or palate were reviewed from GoFundMe. Google searches for cleft lip and palate were evaluated utilizing Google Trends, with values reported as Relative Search Volumes (RSV). Driving distances and travel time to the nearest approved ACPA center were calculated using Google Maps data.
There was a statistically significant difference in average driving distance and travel duration between the different subregions of the US (P
=
0.0059 and 0.026, respectively). The South subregion had the highest proportion of campaigns (n = 259, 40.9%), mean driving distance (105.75 km) and mean driving duration (1 hour 8 minutes). The number of approved teams per state was negatively correlated to both RSV scores (r = -0.38, P
=
0.048) and the number of campaigns (r = −0.34, P
=
0.014).
There is an uneven distribution of ACPA centers among the US subregions. The South seems to have the highest need for care, as identified by proportionate number of campaigns, adjusted driving distances and travel time. This data suggests that underserved areas for cleft care are correlated with greater numbers of hardship campaigns and more internet searches regarding cleft lip and palate.
Lacrimal Ductal Fistula After Lateral Canthoplasty
Authors: Kang Min Seung , Ahn Jung Hyo 
Published: August 2020

Abstract
We report a rare case of lacrimal ductal fistula in a patient who underwent esthetic lateral canthoplasty. A 37-year-old woman was referred to our hospital with tearing in right eye after cosmetic lateral canthoplasty of both eyes. The patient was treated with silicone tube intubation at a local medical center, but the symptoms were not resolved. Lacrimal sac irrigation tests and paranasal computed tomography (CT) were performed to analyze the possibility of lacrimal pathway obstruction. However, there was no evidence of acquired lacrimal duct stenosis. The teardrop leaked out through a small orifice in the right lateral canthal area and it increased in size over time. We identified lacrimal ductal fistula and performed lacrimal fistulectomy. The tearing at right lateral canthus area was resolved. There were no more recurrences nor any other complications 2 years after surgery.
Endoscopic Orbital Reconstruction With Temporalis Muscle Flap
Authors: Sibar Serhat , Karasu Oguzhan 
Published: August 2020

Abstract
Temporalis muscle flap is one of the most commonly used flaps in orbital reconstruction. Although multiple case series in the literature have reported elevation of the flap with an open incision and a retrograde approach from the periorbital region, to the best of the authors’ knowledge, no studies have reported the use of an endoscopic method. Therefore, the authors’ study presents endoscopy-assisted temporalis muscle reconstruction of a defect that occurred in the periorbital region following orbital exenteration. Minimal scarring and morbidity are some of the advantages of endoscopic methods, and healing without complications was achieved in our patient during the postoperative period. To the authors’ knowledge, their study is the first to report the use of temporalis muscle flap in endoscopy-assisted periorbital reconstruction, which is a preferred method for endoscopic surgery.

Published: August 2020

Abstract
A 19-year-old woman consulted for bilateral superotemporal conjunctival lesions that had been present since birth. Physical examination also revealed hemifacial microsomia and bilateral auricular appendages. Medical history included heart, hearing, and neurologic problems. Excision biopsy of these lesions showed nodular proliferations of adipose tissue, which corresponded to the diagnosis of dermolipomas in the setting of Goldenhar syndrome. Complete examination for other first and second branchial arch anomalies is warranted in patients presenting with such lesions.
