The mean prevalence in the whole of Europe is approximately 88/100.000 births (Cornel et al., 1992). There is a variability in the prevalence throughout Europe, with higher figures in the North-West and unexplained lower figures in the South and South-East. CLP may occur unilaterally or bilaterally, and the cleft can be complete or incomplete. Isolated clefts in the palate or the lip do occur. Different combinations of clefts in lip, alveolus and palate are the most common forms (Härtel et al., 1991). Clefts may be associated with known sequences and syndromes such as Pierre Robin sequence, orofacial clefting, Van der Woude, Stickler, Shprintzen, Saethre-Chotzen, Treacher Collins, and Apert syndromes, as well as with other anomalies (Gorlin et al., 1990, Morris et al. 1993). The aetiology and pathogenesis of the disorder are multifactorial. Genetic abnormalities and/or noxious stimuli during the first weeks of gestation, when early development of the face takes place (Pfeifer, 1991), are the main causes. Disturbances in the fusion or merging of nasal and maxillary processes may give rise to various types of clefts (Härtel et al., 1991). Inadequate apoptosis or programmed cell death might be involved in the development of clefts (Vermeij-Keers et al., 1983, 1990; Mangold, 1991). 1.2 Aspects of treatment related to maxillary growth The interdisciplinary treatment of CLP in the Netherlands is basically organized in multidisciplinary cleft palate centres, which are generally attached to university hospitals. The Nijmegen Cleft Palate Centre is one of the major centres in the Netherlands. The treatment in Nijmegen starts, if need be, with presurgical orthopaedic appliances directly after birth, according to the principles of Hotz and Gnoinski (1979), followed by closure of the cleft of the lip at the age of 3-6 months. At the age of 12-18 months, 15 Chapter 1 the soft palate cleft is closed (Kuijpers-Jagtman and Borstlap, 1992). Closure of the hard palate and alveolar cleft is delayed until the age of 8 to 12 years and is performed before eruption of the permanent canines through the alveolar bone (Koberg, 1973; Egyedi, 1985; Witsenburg, 1985; Borstlap et al., 1990; Witsenburg and Freihofer, 1990; Freihofer et al., 1991; Freihofer and Kuijpers-Jagtman, 1993; Freihofer et al., 1993). In other centres, however, different schedules of surgical treatment are used, based on different philosophies and strategies. Early closure of the hard palate is claimed to be beneficial for speech development, and according to several authors it does not cause serious maxillary growth retardation (Pfeifer, 1991; Correa Normando et al., 1992). On the other hand it has been reported that any kind of lip and/or palatal surgery at an early age, gives rise to retardation and impairment of growth and development of the dentomaxillary complex especially in those cases in which the bone is denuded by stripping of the mucoperiosteum and in which healing is allowed by secondary intention (Herfert, 1954; Bardach and Eisbach, 1977; Eisbach et α/. ,1978; Bardach and Mooney, 1984; Wijdeveld et al., 1988; Pfeifer, 1991; Correa Normando et ai, 1992, Noverraz et ai, 1993; Kuijpers-Jagtman, 1995; Leenstra et al., 1995b). Antero-posterior and vertical growth disturbances of the maxillo­ facial structures are less pronounced in cases where the cleft is surgically untreated. In such cases, hardly any visual impact on the profile of the non- cleft side is apparent (Bishara et al., 1976; Derijcke et ai, 1990; Mars and Houston, 1990; Correa Normando et ai, 1992).

Please initial each page, indicating that you have read the page and sign the consent for surgery as proposed by your plastic surgeon and agreed upon by you. GENERAL INFORMATION The use of tissue expanders for breast reconstruction involves a two-stage process. A tissue expander is inserted either at the time of the mastectomy (immediate breast reconstruction) or at a later time (delayed reconstruction). The tissue expander is filled over time to increase the size of the breast mound. Once this is accomplished, a second operation is performed to place a breast implant. Additional procedures such as a capsulotomy or capsulectomy may be performed at the time of the insertion of the implant in order to make changes in the space where the breast implant will be located.

Please initial each page, indicating that you have read the page and sign the consent for surgery as proposed by Dr. Brown and agreed upon by you. GENERAL INFORMATION There are a variety of surgical techniques for breast reconstruction. Breast cancer patients who are medically appropriate for breast reconstruction may consider tissue expander breast reconstruction, either immediately following mastectomy or at a later time. The best candidates, however, are women whose breast cancer, as far as can be determined, seems to be eliminated by mastectomy and other treatments. Breast reconstruction has no known effect on altering the natural history of breast cancer or interfering with other forms of breast cancer treatment such as chemotherapy or radiation. Breast reconstruction with tissue expansion is a two-stage process. It first involves the use of a silicone rubber balloon-like tissue expander that is inserted beneath the skin and often also beneath chest muscles. Saline or air is gradually injected into the tissue expander to fill it over a period of weeks or months. This process allows the skin on the chest to be stretched over the expander, creating a breast mound. In most cases, once the skin has been stretched enough, the expander is surgically removed and replaced with a permanent breast implant.

Distributed under Creative Commons CC-BY 3.0 Abstract Orthodontic tooth movement is brought about by the biomechanical utilization of the physiological mechanisms for bone remodeling in order to achieve optimal occlusion and thereby maximize the esthetic outcome. Distraction osteogenesis is a biomechanical process of bone tissue formation, where the distraction forces which act between the bone segments effect the biological potential of the bone. Though initially used in long bones, through the past years the technique has undergone significant advancements and innovations, that it has had increasing applications in the facial skeleton. The gradual evolution of compact internal appliances has lately led to the use of this concept in the field of orthodontics for moving tooth segments rapidly for an accelerated treatment outcome, and for novel modalities in the treatment of ankylosed teeth. This article is presented under the light of current literature to review the history, evolution and role of distraction in contemporary orthodontics.

  • Tissue Expanders in Post-Burn Alopecia: with Or Without Galeotomies? Expansion Cutanee Dans Les Alopecies Post Brûlures: Avec Ou Sans Galeotomie?
    Annals of Burns and Fire Disasters - vol. XXVIII - n. 3 - September 2015 TISSUE EXPANDERS IN POST-BURN ALOPECIA: WITH OR WITHOUT GALEOTOMIES? EXPANSION CUTANEE DANS LES ALOPECIES POST BRÛLURES: AVEC OU SANS GALEOTOMIE? el Sakka D.m. Assistant Professor of Plastic and Reconstructive Surgery, Faculty of medicine, menofia University, egypt SUMMARY. The tissue expansion technique is part of the reconstructive surgeon’s armamentarium. It provides donor skin that is an optimal match in terms of skin colour, texture, sensation and hair-bearing characteristics. Tissue expansion of the scalp is one of the methods used for the management of alopecia. This method allows the expansion of normal hair-bearing scalp to cover the area of alopecia. Unfortunately, the tough galeal layer prevents easy and fast expansion of the scalp and increases the rate of ex - pander extrusion. A prospective and retrospective comparative analysis of the use of subgaleal expanders with or without gale - otomies to manage post-burn alopecia was conducted in the Burn Unit of the Menofia University Hospital, in the period from Sep - tember 2010 to November 2014. Thirty expanders in 30 patients with alopecia were included in the study. These constitute the ex - perience of a single surgeon. Twenty expanders were applied to the subgaleal plane without galeotomies and 10 were applied with galeotomies. Indications for scalp expansion were mainly post-burn alopecia and scarring. Complications and failures were record - ed. Adding galeotomies to subgaleal tissue expander placement for scalp alopecia decreases the time of expansion, allows a larg - er amount of fluid to be injected each time without inducing pain, and decreases the rate of expander extrusion.

  • Tissue Expansion for Breast Reconstruction Preparation Instructions
    Tissue Expansion for Breast Reconstruction Preparation Instructions What are my instructions? Shower with Bactoshield the night before and morning of each tissue expansion. What should my activity level be? Do not perform household chores or heavy lifting greater than 5 to 10 pounds for 6 weeks after placement of tissue expanders. Do not soak in hot tubs or swim in lakes while the tissue expander is in place. Be Aware: You cannot have an MRI if you have tissue expanders in place. The tissue expanders may be detected via the security scanners at the airport. You will need a note from your Doctor if you plan to travel indicating you have tissue expanders in place with medal. How should I expect to feel? You may experience minor discomfort for 12 to 24 hours after each tissue expansion. This discomfort usually subsides 2 to 3 days after each tissue expansion. The tissue expander may shift after the first or second expansion. You may experience more discomfort on one side than the other if you have bilateral tissue expanders placed. Your posture may change causing you to have some upper and/or mid back pain as you’re expanded. UMHS Plastic Surgery (734) 998-6022 - 1 - Your shoulder range of motion may become stiff; continue to perform the shoulder exercises during the tissue expansion process to prevent shoulder stiffness and a frozen shoulder. You may find it difficult to sleep because you feel tight across the chest and shoulders. You may find it difficult to fit into certain types of tight fitting clothing.

Abstract Background Mucormycosis is a rare invasive and fatal fungal infection. A prompt diagnosis is the most critical aspect for an improved patient outcome. Along with antifungal therapy, radical surgical debridement must be done expeditiously to eradicate this fungus. In this article, we evaluated the feasibility of immediate reconstruction after surgical debridement. Methods A retrospective study was performed at Hospital Regional de Alta Especia- lidad de Ixtapaluca, Estado de México, Mexico, between June 2017 and June 2018. Five patients, three males and two females, with a mean age of 39 years were presented in addition to a literature review based on MEDLINE, Google Scholar, PubMed Central, and Embase platforms until June 2018. Results From our presented series, all five flaps survived and showed no evidence of mucormycosis recurrence or flap loss.
