Publication date: Available online 21 June 2019Source: British Journal of Oral and Maxillofacial SurgeryAuthor(s): J.A. Richards, M.J. Coyle, A.N. BeechAbstractIn recent years, coronectomy of impacted lower third molar teeth has become an increasingly popular alternative to removal. Traditionally, orthopantomograms of mandibular third molars have been used to indicate features that show that the tooth is in close proximity to, or in an intimate relation with, the inferior dental nerve. Some authors...
Introduction: Chronic osteomyelitis is characterized by compromised blood supply and eventual osteonecrosis. Definitive treatment requires aggressive resection of affected bone. The resultant defect poses a unique challenge to reconstructive surgeons. Much of the literature on craniofacial osteomyelitis focuses on infection eradication, rather than subsequent reconstruction. This article reports representative cases from our experience with free flap reconstruction for defects secondary to chronic...
With the development of computer-assisted surgery, preoperational design is detailed in software. However, it is still a challenge for surgeons to realize the surgical plan in the craniofacial surgery. Robot-assisted surgery has advantages of high accuracy and stability. It is suitable for the high-stress procedures like drilling, milling, and cutting. This study aims to verify the feasibility for automatic drilling without soft tissues in model test based on an industrial robot platform. This...
Pharyngocutaneous fistula is a major complication after total laryngectomy, leading to a severe adverse impact for the patient and social activity. The reported incidence ranges from 9% to 25% in the last decade. In this paper, the authors present our experience using chimeric lateral arm free flap for reconstruction of the pharyngo-esophageal segment. Eight patients with pharyngocutaneous fistula were treated with this technique. The flap has 2 skin islands, each one supplied by a perforator coming...

A total of 40 maxillary sinuses were randomly divided into 5 groups: control group which is used...
Introduction: Maxillary hypoplasia after cleft lip and palate (CLP) repair can result in significant functional and aesthetic impairments. Le Fort I osteotomy & advancement and Le Fort I distraction osteogenesis are standard treatment options for individuals with CLP-associated midface retrusion. However, both of these modalities continue to be associated with a high relapse rate. This study describes surgical outcomes of a 2-stage technique utilizing distraction osteogenesis combined with...
The aim of the present study was to evaluate the effects of low-level laser therapy (LLLT) and biphasic alloplastic bone graft material on diabetic bone healing. Induction of diabetes was performed in 14 male Sprague-Dawley rats by intraperitoneal injection of a 50 mg/kg dose of streptozotocin. Two bilaterally symmetrical non-critical-sized bone defects were created in the parietal bones in each rat. Right defects were filled with biphasic alloplastic bone graft. Rats were randomly divided into 2...

Spontaneous osteogenesis of traumatic mandibular defects in the pediatric population remains a relatively rare phenomenon with only 2 patients reported in the literature. In the adult population, a low threshold exists for bone graft placement in the presence of small mandibular gaps, with no role for spontaneous osteogenesis in significant mandibular defects. The approach to traumatic mandibular defects in the pediatric population is not clearly described in the literature and the risks and benefits...
Rigid external distraction device (RED) is an efficient and reliable technique for syndromic craniosynostosis patient's postoperative midface distraction. But the instability of the RED is still a major complication. In this case, the authors reported a novel and simple method to solve the RED movement after Le Fort III osteotomy by using “W-shaped steel wire suspension system” in a child with Apert syndrome whose bilateral temporal bone is extremely thin. The system resisted the rotational force...
Background: Multiple methods are employed to correct short nose deformities, with septal extension graft representing the first choice for Asians. However, the volume of the septal cartilage in many Asian patients is not sufficient to be used alone for such operation. The present work developed a new method combining the septal cartilage with ethmoid bone graft to overcome this issue in Asian patients with short noses. Methods: Thirty-five women with short noses underwent septal extension...
Facial asymmetry is a common maxillofacial deformity which requires surgery to recover the 3-dimensional relationship of bones. The computer-aided design and computer-aided manufacturing (CAD/CAM) has been developed and applied to improve orthognathic analysis and surgery design. How to accurately realize the preoperative design of orthognathic surgery with CAD/CAM occlusal splints during operation remains a big problem. In this study, 24 consecutive patients with facial asymmetry were recruited...
The present study was conducted to compare between extraoral and intraoral approach for botulinum toxin type A (BTX-A) injection into the lateral pterygoid muscle (LPM) in patients suffering from anterior disc displacement with reduction (ADDWR). Fourteen patients suffering from ADDWR were included in this prospective cohort study. Patients were enrolled randomly into 2 groups according to injection approach; where extraoral used in group I, while intraoral approach used in group II. The LPM was...
At our department, the authors performed a periareolar mastopexy and harvested costal cartilage for use in a rhinoplasty through the same periareolar incision. This technique has several advantages compared to the traditional method, including less invasion, minimal chance of a hypertrophic scar and easier postoperative care. However, the location of the incision determines that the fifth costal cartilage is the lowest one accessible. Thus, calcification of the implant material poses a challenge...
A 29-year old woman presented with 2 small and firm subcutaneous nodules on the anterior aspect of the left inferonasal orbital rim. Orbital computed tomography scan showed small well-circumscribed exophytic masses of bone density on frontal process of maxillary bone. The patient refused any surgical intervention in this stage. After 5 years masses demonstrated a significant growth and she requested to do surgery. Complete surgical excision was performed and histopathological diagnosis was consistent...

Non-synostotic plagiocephaly consists in an asymmetry of the skull due to mechanical forces applied in utero or postnatally: main differential diagnosis is with true synostotic asymmetry, which is caused by the premature closure of a suture. The correction of positional forms is mostly conservative, with 3 main strategies: counterpositioning, physiotherapy and helmet therapy. There is no synthesized evidence on which is the most effective.[1,2] The Authors evaluate the modification of antropometric...
Orbital fractures pose specific challenge in its surgical management. One of the greatest challenges is to obtain satisfactory reconstruction by correct positioning of orbital implant. Intraoperative computed tomography (CT) scan may facilitate this procedure. The aim of this study was to describe the early use of intraoperative CT in orbital fractures repair in our center. The authors assessed the revision types and rates that have occurred with this technique. With the use of pre-surgical planning,...
Thorough evaluation of the upper eyelid is essential for diagnosis and management planning in blepharoptosis. In a previous study, our group described a novel force gauge for direct assessment of upper lid force in healthy subjects. In this study, the authors apply the same technique for measuring muscle forces in ptotic eyelids. Patients scheduled to undergo surgical repair of aponeurotic blepharoptosis or dermatochalasis, from July 2017 to August 2018, in a tertiary care medical center, were...
Various local flaps have been defined for small skin defects of the nose. However, the repair of large nasal defects is only possible with flaps allowing a large tissue transfer, such as a free flap, forehead flap, and nasolabial flap. In this study, large nasal defects were reconstructed with extended central artery perforator propeller (CAPP) flaps in an attempt to describe a single-stage procedure as an alternative technique to the median forehead flap. Thirteen large nasal skin defects, including...

The long consolidation period of distraction osteogenesis (DO) may lead to complications such as pain, infection, fracture, scar formation, malunion and delayed union. The aim of this study was to evaluate the effect of systemic Vitamin E application during mandibular DO on new bone regeneration in a rabbit model. 16 adult male 8 months old New Zealand rabbits underwent mandibular lengthening with a distractor for the study. After the latency period of 5 days, the distractor was activated at a rate...
Pterygoid hamular bursitis is a rare craniofacial pain syndrome used to describe palatal and pharyngeal pain due to an enlarged pterygoid hamulus. The pterygoid hamulus is a hook-shaped bony process located bilaterally on each medial pterygoid plate of the sphenoid bone, posterior and medial to each maxillary tuberosity. These processes project downward and anterolaterally; serve as attachment for ligaments and a network of muscles. It can be palpated in patients with a finger palpating the posteromedial...
Tissue necrosis associated with local anesthesia and actinomycosis is rare. Here, the authors present management of excessive palatal necrosis associated with local anesthesia and actinomycotic infection. In oral surgery a simple procedure can lead to severe complications. Thus, preformation of any surgical procedure with a rigorous manner preferably by a qualified clinician may prevent the occurrence of this type of complications. Address correspondence and reprint requests to Damla Torul, DDS,...
