Craniofacial microsomia (CFM) is a congenital anomaly with a variable phenotype. The most prominent feature of CFM is a predominantly unilateral hypoplasia of the mandible, leading to facial asymmetry. Even after correction of the midline, there is often a remaining hard- and soft-tissue deficiency over the body of the mandible and cheek on the affected side. This clinical report describes the skeletal augmentation of the mandible with a patient-specific implant to treat residual facial asymmetry in two female patients with unilateral CFM. Good aesthetic results were achieved in both patients treated with either a Medpor or polyetheretherketone implant without complications after a follow-up time of 55 and 30 months, respectively.

Object The authors present their experience with a protocol for the treatment of patients with complicated shunt infections. Methods Complicated shunt infections are defined for the purpose of this protocol as multiple compartment hydrocephalus, multiple organism shunt infection, severe peritonitis, or infections in other sites of the body. The initial treatment protocol for these patients was 3 weeks of intravenous antibiotic therapy and 2 weeks of twice daily intraventricular/intrashunt antibiotic therapy. Cerebrospinal fluid (CSF) cultures were monitored during therapy and obtained again 48 hours after completion. The shunt was completely replaced. Additionally, follow-up cultures were obtained in all patients 3–6 months after therapy was completed. Results A cure of the infection was achieved in all patients as defined by negative cultures obtained at completion of antibiotic therapy and in follow-up studies. The follow-up period was 2–11 years (mean 4.4 ± 2.5 years). The treatment protocol was modified in the patients treated after 1991, and 18 patients were treated with this modified treatment regime. In these patients, intraventricular antibiotics were administered only once daily for 14 days, and the CSF was cultured 24 hours after antibiotic therapy had been stopped instead of after 48 hours. The results were similar to those obtained with the initial protocol. Conclusions Based on their prospective nonrandomized series, the authors believe that patients with complicated shunt infections can be successfully treated with 2 weeks of intraventricular antibiotic therapy administered once daily, concurrent with 3 weeks of intravenous antibiotic therapy. This protocol reduces length of treatment and hospital stay, and avoids recurrence of infection.

Objective to present a surgical technique for treating patients with recurrent ectropion and severe lower eyelid laxity. Methods Lateral tarsal strip and canthal fixation by osteotomy was performed in 6 patients with recurrent ectropion and 1 patient with extreme lower eyelid laxity secondary to an anophthalmic socket. Preoperative and postoperative photographs were evaluated in order to assess the outcomes of the procedure. Patients were followed up 4 weeks, 6 months, 12 months and 24 months of the postoperative period. The initial symptoms of the patients were eye redness, epiphora, foreign body sensation, aesthetic complaints, and facial asymmetry. Symptoms and aesthetic results were assessed by questioning, photographs, and fluorescein and lissamine green stains taken in each visit. Results No postoperative complications were observed. No recurrence episodes were reported during the follow-up period and physical appearance improvement and symptom severity reduction were maintained during the observation. Conclusion Lateral tarsal strip through osteotomies is an effective surgical procedure for treating severe recurrent ectropion cases or lower eyelid laxity and could be considered as an alternative treatment option or even a primary surgical technique in selected difficult cases.

Condylar hyperplasia (CH) is a rare, self-limiting process manifesting between the first and third decades of life. CH causes facial asymmetry and derangement of the occlusion. Management involves resection of the condylar head and orthognathic surgery. This paper describes the case of a 37-year-old woman with spontaneous onset of CH over a span of approximately 25 years. The condition was managed with resection of the condyle alone, which dramatically improved facial asymmetry and altered the occlusion within a few months of follow up. Orthodontic treatment was then carried out and the patient underwent orthognathic surgery after 3 years. The patient is currently satisfied with her appearance and function and there are no signs of recurrence.

Dentofacial deformities can have a profound impact on patients’ function and facial aesthetics. Traditionally, dentofacial deformities and malocclusion have been managed with growth modification, orthodontic therapy, and orthognathic surgery, or a combination of these modalities. The aim of this article is to discuss the use of patient-specific alloplastic implants as an adjunct or alternative to orthognathic surgery in patients with dentofacial deformities. A 40-year-old man who previously underwent surgically assisted rapid palatal expansion followed by LeFort I osteotomy advancement, intraoral vertical ramus osteotomy setback (IVRO), rhinoplasty, and fat transfer to the malar region presented with a chief complaint of dissatisfaction due to significant facial asymmetry. Tear trough deformity, concave nasal dorsum with nasal tip deviation to the left, submalar fullness, chin deviation to the right, and a poorly defined mandibular border outline were all noted on physical examination. The patient was treated with lower lid blepharoplasty with fat repositioning, buccal fat pad reduction (bichectomy), and patient-specific malar and mandibular border implants. In a patient who has a moderate-to-severe malocclusion and dentofacial deformity, traditional treatment includes orthodontic correction and orthognathic surgery. Patients undergoing primary orthognathic surgery can benefit from alloplastic implants. For patients who have residual maxillary or mandibular asymmetry after orthognathic surgery, the treatment options are secondary orthognathic procedures or facial implants. These patients can benefit from treatment with alloplastic facial implants as an adjunct or alternative to orthognathic surgery to normalize skeletal contours and improve facial aesthetics. Patient-specific alloplastic implants can be used as a powerful adjunct or alternative to orthognathic surgery. Patients with mild occlusal and skeletal deformities who have traditionally been treated with orthodontic therapy alone can benefit from evaluation of alloplastic implants. Patients with residual asymmetries after orthognathic surgery can benefit from alloplastic implants as an adjunct with secondary osteotomies or as an alternative altogether.

This clinical report describes a combined lateral-crestal approach to elevate the sinus floor when placing implants on a wide maxillary posterior ridge. The buccally enlarged osteotomy broadens vision of practitioners and facilitates access of instruments in the sinus. Compared to the traditional lateral approach of sinus lift, the proposed technique may offer a more conservative treatment modality. And a clinical study with sufficient subjects and long term follow up is needed to validate the potential and limitations of the proposed technique.

Scaffolds are used for drug delivery in tissue engineering as this system is a highly porous structure to allow tissue growth.  Although several tissues in the body can regenerate, other tissue such as heart muscles and nerves lack regeneration in adults. However, these can be regenerated by supplying the cells generated using tissue engineering from outside. For instance, in many heart diseases, there is need for heart valve transplantation and unfortunately, within 10 years of initial valve replacement, 50–60% of patients will experience prosthesis associated problems requiring reoperation. This could be avoided by transplantation of heart muscle cells that can regenerate. Delivery of these cells to the respective tissues is not an easy task and this could be done with the help of scaffolds. In situ gel forming scaffolds can also be used for the bone and cartilage regeneration. They can be injected anywhere and can take the shape of a tissue defect, avoiding the need for patient specific scaffold prefabrication and they also have other advantages. Scaffolds are prepared by biodegradable material that result in minimal immune and inflammatory response. Some of the very important issues regarding scaffolds as drug delivery systems is reviewed in this article.
