05). No relapse, suture exposition, hematoma, keloid scar, or infection was observed.

Posterior auricular muscle complex is a strong anatomical structure that includes the trapezius muscle, occipital muscle, extrinsic ear muscles, temporal fascia, and sternocleidomastoid fascia. By elevating this structure as a flap and combining it with an adipo-perichondrial flap, successful results can be achieved in the repair of prominent ear deformities, which prevents relapses and maintains the shape of the ear in the long term.

Incision and drainage of the hematoma is the cornerstone of the surgical treatment and simple compression methods are limited in terms of their ability to eliminate the empty space. Various techniques have been described for the elimination of the death space such as; dental rolls, cotton bolsters, buttons, silastic sheets, etc but compression materials may be insufficient to apply this pressure because of irregular shape of auricle. Resolving these problems, the authors have used thermoplastic splint as a compressive material at 7 patients for elimination of the death space in auricular hematoma treatment.Three-dimensional (3D) technology including 3D reconstruction and 3D printing technology, has been widely used in clinical treatment, especially in surgical planning, and image navigation technology, which can make surgical procedures more accurate, now is also increasingly favored by surgeons. But the combination of those 2 technologies was rarely reported. Thus, this study will preliminarily investigate the feasibility and the effect of the combination of 2 technologies in endonasal skull base surgery. Eight patients were involved in this study (from October 2016 to July 2017 at The Affiliated Hospital of Qingdao University), 5 cases of nasal skull base tumors and 3 cases of foreign body perforation. All operations were done under the assistance of 3D technology and image guidance system. Surgical discussion with patient, preoperative planning and clinical teaching were investigated between 2D images and 3D models by voting. For all cases, 3D reconstruction model and 3D printed model were deemed to be more helpful than CT/MRI images in surgical discussion with the patient; surgical simulation on 3D model in preoperative planning was largely deemed to be helpful and very helpful; and in clinical teaching, 3D models combined with image guidance system were deemed to be more helpful in understanding the disease than using 2D images. Besides, all patients recovered well after surgery, no recurrence and complications were found in the follow-up. The combination of 3D technology and electromagnetic image guidance system could improve surgical efficiency and the quality of clinical teaching.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.Hemifacial microsomia (HFM) is also known as malformation of the first and second branchial arches (BAs), oculoauriculovertebral dysplasia syndrome, and Goldenhar syndrome. Possibilities resulting from CAD/CAM may be a valuable tool to existing procedures to treat these abnormalities. The aim of this study was to report a case where the planning and implementation of an intraorally inserted 2-part patient-specific mandible implant was used for the treatment of HFM esthetic remained problem after orthognathic surgery. A 20-year-old female patient who continued to suffer from the esthetic defect of the unilateral hypoplastic mandible after completion of the orthognathic surgery attended for consultation. Using CT scan and the software Geomagic Freeform (3D Systems, USA), a 2-piece titanium implant was designed and printed to restore the osseous frame of the basal border of the mandible. The base was made of solid polished titanium to minimize soft tissue abrasion. Due to its split design, the implant could be placed anatomically exactly at the mandibular margin via an intraoral access and to avoid damage of the mental nerve. There were no postoperative complications such as infections, soft tissue reactions to the implant, sensitivity disorders, or dehiscence. The occlusion was regular. A measurement of the postoperative x-rays showed a clear increase in bony symmetry. No postoperative pain or trismus was seen. Functionally, the therapy ended with the completion of wound healing and the jaw was fully resilient again. A combined treatment using PSI and additional autogenous fat grafting may represent a valid treatment option for the treatment of facial asymmetry in patients with HFM.Previously, severe upper airway obstruction in patients with retrognathia and glossoptosis has been managed with tracheostomy. However, tracheostomy is associated with significant morbidity. In recent years, mandibular distraction has become an alternative management strategy in infants, but these applications have been limited to patient populations with retrognathia and glossoptosis. The authors present 2 unique cases of patients with KAT6B-related gene disorders, who present with a paradox of tongue-based airway obstruction in the absence of retrognathia. In both cases mandibular distraction osteogenesis with an obliquely oriented vector was successfully performed and both children avoided the need for tracheostomy.Purpose of the present study is to objectively evaluate the number of severe vascular complications, represented by skin necrosis and vision loss or impairment, following facial filler injection. The investigators implemented a review of the literature including articles published on PubMed database without limitation about year of publication, including all reports concerning skin necrosis and vision loss or impairment related to the injection of fillers for cosmetic uses. The search highlighted 45 articles and a total of 164 cases of skin necrosis and vision loss or impairment after injection of different substances. The injection site most frequently associated with complications was the nose (44.5%), followed by glabella (21%), nasolabial fold (15%), and forehead (10%). Results of the present study suggest that injectable filler can cause severe complications even in expertized hands. Treatments in the new defined "Dangerous triangle" must be carefully carried out. Despite our expectations, the highest rates of sever adverse events have been associated with autologous fat transfer practice.
Blood-borne pathogen infections (BPIs), caused by the human immunodeficiency virus, hepatitis C and hepatitis B viruses pose an occupational hazard to healthcare workers. Facial trauma reconstruction surgeons may be at elevated risk because of routine use of sharps, and a higher than average incidence of BPIs in the trauma patient population.

The authors retrospectively reviewed health records of patients admitted to a level 1 trauma center with a facial fracture between January 2010 and December 2015. Patient demographics, medical history, mechanism of injury, type of fracture, and procedures performed were documented. The authors detemined the frequency of human immunodeficiency virus, hepatitis B, and hepatitis C diagnosis and utilized univariable/multivariable analyses to identify risk factors associated with infection in this population.

In total, 4608 consecutive patients were included. Infections were found in 4.8% (n = 219) of patients (human immunodeficiency virus 1.6%, hepatitis C 3.3%, hepatihistory of intravenous drug use).
The purpose of this study was to categorize and compare outcomes and sequels in 2 groups of patients born with unilateral and bilateral complete cleft lip/palate, having their primary cleft palate repair performed in our hospital, by the same surgical team, during 2 different periods of time, to establish which of the 2 surgical reconstructive strategies employed was more effective to decrease sequels.

This is a randomized clinical trial including a total of 291, nonsyndromic patients, primary assisted in our Hospital, between 2002 and 2013, and operated by the same senior surgeon.Two groups of patients of similar characteristics were treated utilizing 2 different surgical procedures according to the considered period. Isolated palates, syndromic patients, secondary and adult cases were considered as exclusion critters. Surgical data was obtained from medical records, and clinical examinations. All the patients were cautiously evaluated by a team expert to verify results, evolution, and sequels.

Variations in the clinical presentation of the unilateral cleft lip resulted in numerous surgical repair techniques used around the world. No universally accepted method exists to evaluate aesthetic surgical results. The purpose of this study is to use the Hubli lip grading system, developed by Smile Train, to evaluate the aesthetic results of unilateral cleft lip repairs based on the surgical technique used.

A retrospective review was conducted of unilateral cleft lip repair operations performed by Smile Train surgeons throughout Africa, Americas, Asia Pacific, and Europe and Middle East between 2014 and 2018. Using the Hubli lip grading criteria, factoring in cleft severity, acceptable outcomes were identified and compared with the surgical technique used.

Eight thousand forty-one unilateral cleft lip repairs were reviewed. The majority utilized the rotational advancement technique (n = 5541, 68.9%) with a statistically significant percentage of acceptable outcomes (92.1%), followed by an acceptance rhe world.The objective of this study is to validate the proof of concept of a 3-dimensional (3D)-printed temporal mandibular joint (TMJ) for use in mandibular distraction in patients with severe craniofacial microsomia (CFM). Patients with Pruzansky-Kaban IIB and III have severe condylar dysplasia and abnormal or absent TMJs, often resulting in upper airway obstruction during infancy. As these patients progress, they require subsequent surgeries to correct facial asymmetry and TMJ function. While studies have shown promising outcomes with costochondral grafting or mandibular distraction without a TMJ in the setting of patients with Pruzansky-Kaban IIB and III it is often unsuccessful in avoiding tracheostomy during infancy. Using an adult head and neck cadaver, the right condylar head was removed to emulate a Pruzansky-Kaban III mandible. A 3D model of an adult skull was obtained. The 3D TMJ was replaced into the cadaver and KLS distractor applied in the vertical orientation. The authors achieved adequate distraction using a 3D-printed TMJ.
