Nasal continuous positive airway pressure (nCPAP) is utilized increasingly to treat pulmonary immaturity in premature neonates. Nasal injury is common with nCPAP use, with full thickness tissue loss at the columella among the most devastating complications.Columellar necrosis often imparts a full thickness injury to the overlying columellar skin, the medial crura of the lower lateral nasal cartilages, as well as the anteromedial inner nasal mucosal lining, and potentially the anterior septal cartilage. Consequently, the columella can become scarred and shortened...

BACKGROUND: Free fibula flap is an option for primary restoration after disarticulation mandibular resection, though literature on technique refinements is scarce. The authors hypothesized that inset of the masseter, the key mandibular elevator muscle, at the reconstructed mandible may optimize functional recovery. METHODS: All patients undergoing reconstruction of mandibulectomy-condylectomy defect (January 2009 to January 2014) by means of a fibular flap were prospectively studied...

Osteoma is a benign osteogenic tumor, which is characterized the slow-growing proliferation of compact or cancellous bone. The etiology of the lesion is not well established. Among the hypotheses, the following are related: a traumatic factor, infectious processes, or true neoplasm due to the origin of cartilaginous cells. It can present at any age, usually in young adult individuals, with equal prevalence in both sexes. The clinical characteristics of the peripheral osteoma are represented by slow asymptomatic growth, which leads to swelling and, thus, facial asymmetry...

BACKGROUND: Radical surgical resection as a treatment modality for oral cancer often leads to an extensive deficit in both the maxillary and mandibular levels, where the use of a palatal obturator prosthesis (POP) or removable partial denture (RPP). The aim of this study was to evaluate the treatment with POP and RPP in patients treated for oral cancer in the Unit of Prosthetic Rehabilitation of the University Hospital Virgen del Rocío in a period of 20 years. MATERIAL AND METHODS: Retrospective descriptive study during the years 1991 and 2011 analyzing oral cancer type, characteristics, treatment and follow-up...

BACKGROUND: Juvenile psammomatoid ossifying fibroma (JPOF) is a rare fibro-osseous lesion that usually occurs in the facial bones. The pathognomonic histopathologic feature is the presence of spherical ossicles, which are similar to psammoma bodies. It is considered to be a unique lesion because of its reported tendency to occur in children and adolescents and its tendency for locally aggressive growth. Because this lesion is aggressive in nature with high recurrence rate, early detection and complete surgical excision are essential...

OBJECTIVE: This article aims to highlight the rehabilitation of a geriatric patient with an orofacial cheek defect by an extraoral silicone prosthesis. METHODOLOGY: Structured extra- and intra-oral examination of tissues coupled with a justified choice of impression materials, techniques, and prosthetic rehabilitation with a high-temperature vulcanizing silicone was done. RESULTS: The presence of compressible tissues, static appearance of the prosthesis during patient's facial movements, variability in complexion of the skin around the defect, and manipulating heat-vulcanized silicone were the challenges faced during clinical procedures...

Surgical treatment of advanced facial tumours is often physically, functionally and emotionally debilitating. The resulting defects often give grounds for surgical reconstruction, prosthetic reconstruction or a combination of both. During the past two decades, huge advances have been achieved in the development of prostheses. This has led to improved rehabilitation of facial defects. In the clinic of the Netherlands Cancer Institute - Antoni van Leeuwenhoek, both adhesive- and implant-retained facial prostheses are used...

Nonsurgical prosthetic interventions are often proposed after repeated grafts have failed to restore irradiated facial defects. This report describes a facial prosthetic reconstruction following ablative surgery for a sizable facial tumor by using a novel custom-made magnet-bearing substructure, which connected with an exposed part of the mandibular reconstruction plate. The defect involved the entire left lower part of the face and angle of the mentum. This reconstructive technique, together with an added surface texture with hair-like silicone strands, effectively addressed the cosmetic needs of the patient...

Previous studies have used principal component analysis (PCA) to investigate the craniofacial relationship, as well as sex determination using facial factors. However, few studies have investigated the extent to which the choice of principal components (PCs) affects the analysis of craniofacial relationship and sexual dimorphism. In this paper, we propose a PCA-based method for visual and quantitative analysis, using 140 samples of 3D heads (70 male and 70 female), produced from computed tomography (CT) images...

Facial Paralysis (FP) profoundly impairs the life of individuals, both functionally and psychosocially. Surgical approaches to treat this condition are myriad, but the ultimate goal is to restore symmetry and movement. Ablative surgery for tumors of the head and neck region are amongst the most common etiologies causing FP and this group of patients represents unique challenges. Surgical defects may have multiple competing reconstructive requirements and addressing the FP must be considered in this context...

Frey's syndrome and infra-auricular depressed deformities are the ones of the most common complications that can occur after total parotidectomy. We report 1 case of pleomorphic adenoma occurred in the deep lobe that obtained good results from using acellular dermal matrix (ADM) after total parotidectomy. A 24-year-old man visited the hospital with oval shape mass in right mandibular angle which of 4 cm in size was found in the deep lobe of right parotid gland from Magnetic resonance imaging scanning and a pleomorphic adenoma was suspected...

Perfect facial and body symmetry is an important aesthetic concept which is very difficult, if not impossible, to achieve. Yet, facial asymmetries are commonly encountered by plastic and reconstructive surgeons. Here, we present a case of posttraumatic facial asymmetry successfully treated with a unique concept of facial flap repositioning. A 25-year-old male patient visited our department with severe posttraumatic facial asymmetry. There was deviated nasal bone and implant to the right, and the actual facial appearance asymmetry was much more severe compared to the computed tomography, generally shifted to the right...

BACKGROUND: The cheek rotation flap has sufficient blood flow and large flap size and it is also flexible and easy to manipulate. It has been used for reconstruction of defects on cheek, lower eyelid, or medial and lateral canthus. For the large defects on central nose, paramedian forehead flap has been used, but patients were reluctant despite the remaining same skin tone on damaged area because of remaining scars on forehead. However, the cheek flap is cosmetically superior as it uses the adjacent large flap...

REVIEW
Jiye Kim, Jin-Hee Choi, Yoon Kyu Chung, Sug Won Kim
Panfacial bone fracture is challenging. Even experienced surgeons find restoration of original facial architecture difficult because of the severe degree of fragmentation and loss of reference segments that could guide the start of facial reconstruction. To restore the facial contour, surgeons usually follow a general sequence for panfacial bone reduction. Among the sequences, the bottom-to-top and outside-in sequence is reported to be the most widely used in recent publications. However, a single sequence cannot be applied to all cases of panfacial fractures because of the variations in panfacial bone fracture patterns...

The nonsyndromic cleft is one of the most frequent congenital defects in humans. Clinical data demonstrated improved and almost scarless neonatal healing of reparative surgery. Based on our previous results on crosstalk between neonatal fibroblasts and adult keratinocytes, the present study focused on characterization of fibroblasts prepared from cleft lip tissue samples of neonates and older children, and compared them with samples isolated from normal adult skin (face and breast) and scars. Although subtle variances in expression profiles of children and neonates were observed, the two groups differed significantly from adult cells...

Hominoid cranial evolution is characterized by substantial phenotypic diversity, yet the cause of this variability has rarely been explored. Quantitative genetic techniques for investigating evolutionary processes underlying morphological divergence are dependent on the availability of good ancestral models, a problem in hominoids where the fossil record is fragmentary and poorly understood. Here, we use a maximum likelihood approach based on a Brownian motion model of evolutionary change to estimate nested hypothetical ancestral forms from 15 extant hominoid taxa...

BACKGROUND: Tunneled transposition of the facial artery myomucosal (FAMM) island flap on the lingual side of the mandible has been reported for intraoral as well as oropharyngeal reconstruction. This modified technique overcomes the limitations of short range and dentition and further confirms the flexibility of the flap. This paper presents a case of reconstructing secondary soft palatal defect due to flap necrosis following two-flap palatoplasty in irradiated patient with lingually transposed facial artery myomucosal island flap...
