Authors: Sayin Ibrahim , Yazici Zahide Mine , Abakay Mehmet Akif , Saygan Gulsun Basak , Gunes Selcuk 
Published: September 2020

Objective:
To evaluate the demographic factors, trauma type, treatment, and long-term results in patients with nasal septal hematoma (NSH) and nasal septal abscess (NSA) in pediatric age group.

Methods:
Between the years 2006 and 2019, patients who received a diagnosis of NSA and NSH were included for the study. Demographic data, the surgical findings, and long-term follow-up results were recorded.

Results:
A total of 68 patients were identified. Forty-five patients were diagnosed as NSA and 23 patients were diagnosed with NSA. Mean age of the patients was 7.00 ± 3.33 years. Patients did not differ in terms of age, gender, and etiology. Mean duration of the symptoms was significantly high in NSA group (4.11 ± 4.00 days for NSH and 7.61 ± 7.71 days for NSA, P = 0.011). Associated nasal fracture was significantly high in NSH group. Previous nasal examination was significantly high in NSA group. Epistaxis was present significantly high in NSH group (P = 0.013). Fever and purulent nasal discharge was observed significantly high in NSA group. Forty-seven (n = 47) patients can be reevaluated for long-term deformity (NSH, n = 34 [72.34%] and NSA, n = 13 [27.65%]). Mean follow-up period of the patients was 8.7 years. In total, 61.7% of the patients experienced minor or major sequelae. Both NSA and NSH groups did not differ in terms of minor sequelae and major sequelae. No sequleae was significantly high in NSH group (for NSH n = 17/34-(50,0%); for NSA n = 1/13- (7,7%), p = 0.008). Both NSA and NSH groups did not differ in terms of no sequelae and minor sequelae.

Conclusion:
The NSH and NSA are uncommon conditions that needed prompt diagnosis and intervention.

Published: September 2020

AbstractThis study aimed to investigate the effects of systemic propranol on the osseointegration of titanium implants. After the surgical insertion of titanium implants into the metaphyseal part of the tibial bone, the rats were randomly divided into 2 equal groups: the control (CNT) (n = 10) and propranol group (P) (n = 10); CNT: Rats received no further treatment during the 4 week experimental period after surgery. Rats received 10 mg/kg propranol in every day during the 4 week experimental period in PRP group after the surgical insertion of the implants. After the experimental period, the rats were euthanized, blood serum were collected to biochemical analysis and the implants and surrounding bone tissues were used for the histopathologic analysis. To analysis of the data between tests and controls student T test was used. There were no significant differences in the biochemical parameters (alcaline phosphatase, calcium, phosphor) of the groups (P > 0.05). Bone implant connection (BIC) ratios was detected higher in test animals compared with the controls (P < 0.05). Systemic propranolol may increases titanium implant osseointegration.

Authors: Zavattero Emanuele , Ramieri Guglielmo , Agrò Giovanni , Fasolis Massimo , Garzino-Demo Paolo , Borbon Claudia 
Published: September 2020

Background:
The possibility of placing dental fixtures in the reconstructed regions allows us to overcome the problems related to dental rehabilitation with removable prosthesis. The aim of this study was to assess the clinic-radiological outcome in a series of patients who underwent fibula flap jaws reconstruction and rehabilitation with implant-supported prosthesis with a minimum follow-up of 24 months.

Material and Methods:
The study included 10 patients who underwent reconstruction with fibula free flap between 2010 and 2018. Albrektsson criteria were used to define the implant survival. The follow-up evaluation was performed according to a standardized protocol including clinical examination, radiological evaluation (panoramic radiograph) and patient interview.

Results:
A total of 45 implants were positioned.
The time between mandibular reconstruction and implant placement ranged from 13 months to 39 months.
The prosthesis used was fixed in 6 cases and supported overdenture in 4 cases.
No implant failure was observed.
Regarding implant survival no infections were observed in these series. Nine patients out of 10 had no pain and signs of mobility. Seven patients out of 10 had absence of peri-implant radiolucency at the panoramic radiograph.
One patient presented with an overgrowth of granulomatous soft tissue around the implant abutments that caused pain.

Conclusions:
Implant placed in vascularized bone grafts are a safe and reliable opportunity to rehabilitate patients following mandibular resection. The results of this series demonstrate a high survival rate for implants placed in reconstructed mandibles with an improvement of the quality of life.
Laryngeal Osteoblastoma: Unusual Location in Arytenoid Cartilage
Authors: Avci Hakan 
Published: September 2020

Abstract
Osteoblastoma is a benign bone tumor with a slow growing and local aggressive nature. This tumor type is usually localized in the cervical vertebra and rarely involves laryngeal cartilage structures. Very few osteoblastoma cases have been reported in the literature. Here we present laryngeal osteoblastoma originating from arytenoid cartilage in a patient with a history of cordectomy due to glottic squamous cell carcinoma.

Authors: Du Hong , Zhang Dong , Zong Xianlei , Song Guodong , Zhao Jingyi , Yang Changsheng , Guo Xiaoshuang , Lai Chenzhi , Jin Xiaolei 
Published: September 2020

Abstract
Auricular cartilage is a common autologous graft material for rhinoplasty. Even though surgical techniques for the harvest of cartilage graft are well established, the management of the postoperative dressing fixation is still limited. Therefore, the authors propose a simple dressing fixation method in which gauze strips instead of gauze block or wet cotton, the suture of tie-over dressing fixed just through the cartilage rather than the full thickness of the auricle, a vaseline gauze interposed between the stitch knot and the skin and no additional pressure dressings postauricularly. No case of hematoma, infection and skin necrosis of the donor site was observed. This simple and reproducible technique provides perfect and homogeneous adhesion of the dressing all over the conchal cartilage while decreasing the risk of postoperative hematoma and discomfort.
Reconstruction of a Gunshot-Caused Mouth Floor Defect Using a Nasolabial Flap and a De-Epithelialized V-Y Advancement Flap
Authors: Hwang Kun , Ma Sung Hwan 
Published: September 2020

Abstract
We present reconstruction of a gunshot-caused mouth floor defect using a nasolabial flap and a de-epithelialized V-Y advancement flap.
A 58-year-old man presented 14 days after bullet injury passed from anterior chin to the right postauricular area. Upon examination, the central incisors, alveolar bones, and soft tissues of the mouth floor were lost. Bone fragments and failed miniplates were exposed. Pus discharge filled the defect.
On the 23rd post-trauma day, right unilateral nasolabial flap was used to cover the oral side of the mouth floor. This flap was centered on the nasolabial fold and its base was situated on the commissure of the lips. The flap was raised in the soft tissue, just superficial to the facial muscles, transferred into the oral cavity through an incision made in the cheek mucosa, and sutured to the margin of the defect. A de-epithelialized dermal and subcutaneous flap was used to reconstruct the deep portion of the mouth floor through the V-Y advancement method. At the lower border of the mandible, a 3-cm-wide V-Y advancement flap was designed. The de-epithelized portion was inserted into the mouth floor and sutured to the defect margin. On 30th post-trauma day, left commissure-based buccal mucosal flap was used for the gingivobuccal sulcus defect. The apex was near the retromolar trigone. The elevated flap was transferred to the lower gingivobuccal sulcus defect. On POD 28, the nasolabial flap and commissure-based buccal myomucosal flap was divided and inset respectively.
These flaps can be used for moderate-sized mouth floor defects.
Analysis of Head and Neck Primary Cutaneous Mucinous Carcinoma: An Indolent Tumor of the Eccrine Sweat Glands
Authors: Behbahani Sara , Pinto Jessica O. , Wassef David , Povolotskiy Roman , Paskhover Boris 
Published: September 2020

Background/Objectives:
Primary cutaneous mucinous carcinoma (PCMC) of the head and neck is a rare pathologic entity that is an adenocarcinoma of the eccrine sweat glands. Though it has low metastatic potential, it does have a significant recurrence rate. Due to its rarity, its clinical features are not well-known.

Methods:
The authors searched the National Cancer Database (NCDB) for all cases of PCMC with primary sites of the skin of the head and neck confirmed histologically diagnosed from 2004 to 2016. Those with missing survival information were excluded. Kaplan-Meier (KM) and Cox proportional-hazards models were used to analyze the epidemiology and survival outcomes of PCMC.

Results:
The authors analyzed 289 cases. Females were more commonly affected (58.8%; P < 0.05) with the most common primary sites being the eyelid (41.9%) and scalp/neck (25.3%). The average age of diagnosis was 63.8 years (± SD 12.5). Almost all patients received surgery as standalone treatment (92.7%) with wide local excision being the common surgery performed (36.3%). Mohs surgery represented 15.2% of surgically treated cases. Mean overall survival (OS) was 11.4 years with 5-year and 10-year OS being 85.0% and 78.0%, respectively. Most cases were localized at diagnosis with only 2% metastatic at presentation. KM analysis indicated that surgical procedure type, age, tumor diameter, Charlson-Deyo Comorbidity Score, facility type, and stage were significant predictors of OS (P < 0.05). Cox proportional-hazards analysis did not reveal independent association of the aforementioned factors with OS.

Conclusion:
Primary cutaneous mucinous carcinoma has an excellent prognosis with 98% of cases being diagnosed in Stage I and Stage II. As most cases present in the eyelid, special attention should be given to surgical treatment to ensure optimal aesthetic outcomes in this sensitive region. This study represents the largest cohort of head and neck PCMC studied to date.
Insertion Tendinosis of Stylomandibular Ligament: Ernest Syndrome
Authors: Jose Anson , Rawat Aditi , Nagori Shakil Ahmed 
Published: September 2020

Abstract
Insertion tendinosis of stylomandibular ligament (SML) or Ernest syndrome is a very rare and under reported head and neck pain disorder. The pain originates from the insertion of stylomandibular region and radiates to the temple, lateral side of the neck and temporomandibular joint (TMJ). The diagnosis is confirmed by palpation of SML and local anesthetic block at the insertion of SML. The authors report 4 patients who presented with chronic pain which radiated to the TMJ and temple and did not respond to conservative management. All patients after diagnosed with Local anesthetic block were given methylprednisolone injection at the insertion of SML. Complete remission of pain was seen at 12 months of follow up without any recurrence. Craniofacial surgeons involved in the treatment of various head and neck pain should include this less documented syndrome in their differential diagnosis when treating TMJ disorders.

Published: September 2020

Abstract
Facial nerve palsy is an exceedingly debilitating condition, incapacitating functional and aesthetic facets of the face. Orthodromic transfer of temporalis muscle is an easy and predictable technique which offers early animation of oral commissure and lower face. A retrospective chart review of 6 patients of facial palsy treated with orthodromic temporalis tendon transfer for facial reanimation is presented. The technique consisted of intra-oral coronoidectomy followed by attachment of fascia lata grafts from the coronoid to the commissure, the upper and lower lips via small cutaneous incisions. Contraction of the temporalis, pulls the fascia lata extensions thereby reanimating the lower face. 4 male and 2 female patients with an age range of 25 to 49 years were treated. Simultaneous fat grafting (2 patients), depressor labi inferioris muscle resection (2 patients) and wedge excision of nasolabial fold (2 patients) was done as ancillary procedures. Post-operative smile evaluation was carried out using the Terzis and Noah facial grading system. Patients were asked to smile with and without biting, and photographs and video were taken. The results were graded from 1 to 5 based on a 5-point scale (ie, poor, fair, moderate, good, and excellent) by an independent observer. The results were excellent in 1 patient (Terzis grading 5/5) and good in the remaining 5 patients (Terzis grading 4/5). Excursion of the oral commissure ranged from 6 to 10 mm. Our experience indicates that temporalis tendon transfer for facial reanimation has a short learning curve and provides early predictable outcome without significant complications. This single-stage, day-care procedure can be easily incorporated by maxillofacial surgeons to expand their surgical spectrum.

Published: September 2020

Background:
Aesthetic surgical reconstruction of auricular keloids is still a conundrum. This study introduces our experiences in analyzing the anatomic morphological features of auricular keloids, and devising optimized surgical procedures accordingly.

Methods:
A total of 129 ears with auricular keloids were classified and operated. All patients were followed up for at least 12 months.

Results:
According to their anatomic positions, auricular keloids were divided into 3 Groups (A, B, and C). The morphological features of keloids were further interpreted according to Chang-Park classification of earlobe keloids. The authors optimized surgical procedures according to the anatomic morphological features from a range of surgical techniques. The recurrence rate of Group C was statistically higher than Group A and B. There was no significant difference in recurrence rate between keloids treated with “primary suture” and “filleted flaps.”

Conclusions:
According to the anatomic positions and morphological features of auricular keloids, we could conveniently devise optimized surgical strategies to obtain aesthetic reconstruction of auricular keloids.
The Role of Autologous Platelet Concentrates in the Treatment of Medication-Related Osteonecrosis of the Jaw
Authors: Ye Peng , Wei Tai , Lu Zhi-Yue , Cai Ye-Jun 
Published: September 2020

Abstract
The frequent refractory response of patients to the treatment of medication-related osteonecrosis of the jaw (MRJON) has attracted clinicians’ attention to several treatments. However, they are at best, palliative, and have a higher failure rate than previous treatments. The present meta-analysis was performed to evaluate the clinical effectiveness of autologous platelet concentrates (APCs) combined with surgery in the treatment of MRONJ. The authors conducted a meta-analysis involving a systematic search of PubMed, EMBASE, Wiley Online Library and the Cochrane Library for eligible studies from their inception to November 2019, in accordance with preselected criteria. The inverse variance method was applied to fixed or random effects models based on the heterogeneity of the studies. Thirteen studies that investigated APCs in the treatment of MRONJ were eligible for inclusion in the meta-analysis of 223 patients and 33 lesions. The pooled success rate of APCs combined with surgery for MRONJ was 90% (95%CI, 80%–97%) and the pooled OR was 7.67 (95%CI, 2.10–27.98), indicating the combination was 7.67 times more effective than surgery alone. The results suggest that the use of APCs is a promising therapeutic regimen, as it provided additional benefits to surgery in the treatment of MRONJ. To achieve the benefits, a tension-free primary closure of the soft tissue is recommended as well. Randomized studies with large sample sizes is warranted to confirm our finding.
The Morpho-Functional Three-Dimensional Analysis for Zygomatic Implants: A Clinical Tool With Surgical Implications
Authors: Fernández-Olarte Humberto , Gómez-Delgado Andrés , Gutiérrez-Quintero Juan G. , Rodríguez-Sáenz Álvaro , Castro-Núñez Jaime 
Published: September 2020

Abstract
Zygomatic implants (ZIs) have been used successfully for the rehabilitation of jaws with severe atrophy for the past 2 decades. The development of computed tomography, three-dimensional (3D) analysis software, and stereolithographic models has positively impacted the development of preoperative planning. This article describes the protocol developed by the Department of Oral and Maxillofacial Surgery of El Bosque University, Bogotá, Colombia, through 10 years of experience, for the installation of ZIs, covering from the times when the implants were placed through intraoperative guidance, until now, in which drilling guides developed by computer-aided design and computer-aided manufacturing are used, without neglecting in their design multiple factors that must be considered. To date, this protocol for the treatment of patients with atrophic jaws through ZIs includes a detailed clinical examination, in which variables such as bone and dental relationship between the jaws, oral opening and dynamic interaction between soft cervicofacial tissues are considered. It also includes a 3D computed tomography planning for the design and preparation of surgical guides whose insertion patterns must be executable during surgery. Together, clinical and imaging analysis converge in what it has been called morpho-functional 3D planning.

Published: September 2020

Introduction:
Paranasal sinus (PNS) mucoceles may involve orbit and have ophthalmic manifestations. The objective of this study was to investigate the clinical and radiological features affecting the ophthalmic manifestations in patients with PNS mucoceles involving the orbit.

Methods:
Fifty-two patients underwent endoscopic sinus surgery for PNS mucoceles with orbital involvement were investigated. Ophthalmic manifestations included exophthalmos, ocular pain, diplopia, visual disturbance. The correlation between ocular symptoms and the mucocele volume, origin site of mucocele, and the involvement of extraocular muscles or optic nerve were evaluated.

Results:
Ophthalmic manifestations were significantly higher in the anterior ethmoid and frontal sinus involvement. Exophthalmos was significantly increased in the involvement of anterior ethmoid sinus, frontal sinus, and superior group ocular muscles, but decreased in the mucocele of maxillary sinus. Ocular pain was significantly lower in the involvement of anterior ethmoid sinus, frontal sinus, and superior group ocular muscle. Diplopia showed no significant differences among clinical and radiological parameters. Visual disturbance was significantly higher in the involvement of posterior ethmoid sinus and sphenoid sinus. The volume of mucocele, relation to optic nerve, adjacent bony change, and duration of ocular symptom had no significant effect on ocular symptoms in patients with PNS mucoceles involving the orbit.

Conclusion:
The volume of mucocele did not affect the ophthalmic manifestations in patients with PNS mucoceles involving the orbit. Exophthalmos, ocular pain, and visual disturbance were significantly correlated with the involved sinus of PNS mucoceles.

Published: September 2020

Abstract
Scars are significant complications of wound healing and associated with negative physical, psychological, and cosmetic effects. Scar revision and laser treatment have been used over the past century to improve many different types of scars. Here, we evaluated the effectiveness of early combined carbon dioxide ablative fractional laser (AFL) and pulsed dye laser (PDL) treatment after scar revision. Fourteen patients who underwent scar revision were enrolled. All patients were treated with both a 10,600-nm AFL and a 595-nm PDL commencing 2 weeks after scar revision and continuing at 4-week intervals for a total of 4 treatments. Vancouver Scar Scale scores were evaluated before treatment and 5 months after the final treatment. All Vancouver Scar Scale scores improved significantly except that of scar height. We encountered no adverse complications (wound disruption, or hyper- or hypopigmentation) during follow-up. Early combined carbon dioxide AFL and PDL treatment after scar revision effectively and safely minimized scar formation.

Published: September 2020

Introduction:
Craniofacial trauma among athletes of various sports has been well detailed and described. Despite this research, there is a dearth of literature describing the nature of facial trauma secondary to volleyball, despite its global popularity.

Methods:
A cross-sectional analysis of volleyball-related facial trauma was conducted using the National Electronic Injury Surveillance System (NEISS) database from 2009 to 2018. Patient demographics (age, sex, and race), medical injury information (injury type and location), and disposition (observed and discharged, admitted, deceased) were collected and analyzed. χ
2 testing was performed to compare categorical variables.

Results:
A total of 235 volleyball-related facial traumas were recorded with an estimated 10,424 visits occurring nationally. The majority of injuries were among young adults aged 20 to 29 years (52.3%) and was evenly distributed for men and women. Lacerations were the most frequent injury type (37.9%), whereas the face was the most common site of injury (41.7%). The majority of fractures involved the nose (71.4%) and among individuals aged 20 through 49 (90.5%). Males had significantly more lacerations than females (75.3% vs 24.7%), whereas females had significantly more contusions/abrasions (64.5% vs 35.5%) and concussions (72.9% vs 27.1%).

Conclusions:
Volleyball-related craniofacial injuries can vary depending on patient demographics. This information can help with the development of safety and preventative measures for individuals participating in the sport.
