Penis augmentation by application of silicone material: complications and surgical treatment.

BACKGROUND: Complications resulting from enlargement of the penis by applications of unknown types of silicone and mineral oils are well described. Surgical removal of the tissue altered by inflammation leads to the development of defects of various sizes, often circular from the glans penis to the scrotum. The options of subsequent surgical treatment described in literature are not very extensive. Most defects are managed with skin grafting, rarely V-Y advancement or bilateral scrotal flaps. METHODS: We present a 36-year-old patient after application of unknown silicone material into the penis for cosmetic enlargement. After the application developed severe inflammation with ulceration and necrosis around the penis. Conservative treatment was not effective, therefore, the infiltrated skin with subcutaneous tissue of the entire penis was surgically removed. The resulting defect was covered by implantation of the penis under the skin of the scrotum. RESULT: There were no complications in the postoperative course, pain that was present before the surgery immediately subsided. Skin suture healed completely within 14 days. Three months after the surgery the patient returned to normal sexual life. CONCLUSIONS: Implantation of the penis under the skin of the scrotum is a fast, safe and effective method that can treat most of the circular skin defects of the penis. Scrotal skin is thin, soft, elastic and creates abundant and good cover around the entire penis.

Extension of orofacial cleft size and gestational bleeding in early pregnancy.

OBJECTIVE: The oronasal cavity in humans develops during embryonic day 30-60. There are three critical periods when this process can be affected, resulting in a specific type of orofacial cleft: cleft lip (CL), cleft palate (CP), or most serious, total cleft lip+palate (CLP). We assessed whether gestational bleeding during early pregnancy might act to produce a non-specific worsening of embryo status resulting in extension of the basic cleft type (CL or CP) into more serious CLP. STUDY DESIGN: In a group of the child patients with orofacial clefts, the cleft spectrum was correlated with first trimester gestational bleeding reported by the mother. Data were also related to the gender of patients, hereditary factors and additional malformations. RESULTS: Among 2524 mothers who gave birth to babies with an orofacial cleft in the Czech Republic during 1983-2009, 253 (10.0%) had gestational bleeding. Among the children with an orofacial cleft, 497 (19.7%) had an orofacial cleft among relatives and 297 (11.8%) exhibited an additional congenital malformation. In comparison with mothers without bleeding, there was significant increase of children with CLP (p < 0.01) at the expense of children with CP, whose number significantly decreased (p < 0.01) in the bleeding mothers. In the group of children with clefts among relatives we did not find any significant change associated with bleeding. The maternal bleeding was more frequent in children with additional malformations, but this difference was not significant (p = 0.112). CONCLUSION: We hypothesize that size/extent and therefore seriousness of orofacial cleft might increase as a consequence of hypoxia resulting from gestational bleeding.

Three-dimensional development of the upper dental arch in unilateral cleft lip and palate patients after early neonatal cheiloplasty.

OBJECTIVES: This prospective morphometric study evaluated the growth of the upper dental arch in UCLP patients after early neonatal cheiloplasty and compared the selected dimensions with published data on non-cleft controls and on later operation protocol patients. METHODS: The sample comprised 36 Czech children with nonsyndromic complete UCLP (cUCLP) and 20 Czech children with nonsyndromic incomplete UCLP (UCLP + b). 2-D and 3-D analyses of palatal casts were made at two time points: before neonatal cheiloplasty at the mean age of 3 days (±1 day), and 10 months after surgery at the mean age of 10 months (±1 month). RESULTS: The upper dental arch of cUCLP and UCLP + b patients showed similar developmental changes, but the cleft type influenced growth significantly. The initial high shape variability in cUCLP patients diminished after 10 months, and approached the variability in UCLP + b patients. Both the width and length dimensions increased after surgery. Important growth concerned the anterior ends of both segments. The width and length dimensions illustrated similar growth trends with non-cleft controls and UCLP patients who underwent later cheiloplasty. CONCLUSION: Early neonatal cheiloplasty caused no reduction in the length or width dimensions during the first year of life. Our data suggest a reconstructed lip has a natural formative effect on the actively growing anterior parts of upper dental arch segments, which cause narrowing of the alveolar cleft.

Our first experience with primary lip repair in newborns with cleft lip and palate.

The article summarizes the results of early primary lip repair in 44 newborns with cleft lip and palate. We present a study of the first 44 patients to undergo the surgery before the age of 1 week as performed by a surgeon who used a modified method according to Tennison with a nasal correction. Early lip surgeries started in 2005. Cleft patients are under the care of a multidisciplinary team. Preliminary results are very encouraging; we observed excellent esthetic results concerning lip scars and the appearance of the nose. We did not notice any impact on the maxillary development due to the short time interval. We consider early lip surgery with nasal correction the best method, and we would like to continue with it, monitoring its impact on the maxillary and nasal development.

Three-dimensional evaluation of facial morphology in pre-school cleft patients following neonatal cheiloplasty.

PURPOSE: To evaluate the facial morphology of pre-school patients with various types of orofacial cleft after neonatal cheiloplasty in pre-school aged children; and to compare facial variability and mean shape with age-corresponding healthy controls. MATERIALS AND METHODS: The sample included 40 patients with unilateral cleft lip (CL), 22 patients with unilateral cleft lip and palate (UCLP), and 10 patients with bilateral cleft lip and palate (BCLP). Patients were divided into two age categories, with a mean age of 3 years and 4.5 years, respectively. The group of healthy age-matched controls contained 60 individuals. Three-dimensional virtual facial models were evaluated using geometric morphometry and multivariate statistics methods. RESULTS: Statistically significant differences were found between each of the cleft groups and the controls. Color-coded maps showed facial shape deviations, which were located mainly in the nasal area and philtrum in all groups examined, and also in the buccal region and the chin in patients with UCLP or BCLP. These differences became more apparent, but not significantly so, in the older age category. CONCLUSION: Facial deviations typical of patients with clefts were observed in all of the patient groups examined. Although the analysis showed statistically significant differences in overall facial shape between patients and controls among all groups tested, the facial morphology in patients who have undergone only neonatal cheiloplasty (CL) is influenced to a small extent and may be considered satisfactory. More severe cleft types (UCLP, BCLP) together with palatoplasty, are reflected in more marked impairments in facial shape.

In vitro differences of neonatal and later postnatal keratinocytes and dermal fibroblasts.

Skin healing process is postnatally always associated with scarring of various extent. Based on the clinical experience of plastic surgeons, the healing after lip cleft reconstruction is surprisingly almost scar-less when it is carried out within a few first days after birth. This phenomenon is not seen in delayed cases. In order to decipher causative mechanism, we have isolated and studied principal cell populations, keratinocytes and fibroblast, from residual tissue samples after reconstructive operation (N=39) performed at various age (0-9 years). These cells play the pivotal role in the healing and that is why we focused on description of their phenotype and also functionality with respect to age. We have identified a population of remarkably small cells in explants from newborns (day 0-10). These small cells were strongly positive for markers of low differentiated keratinocytes, keratin-8 and -19, and moreover also for vimentin. In the explants cultures from older babies this population was missing. Fibroblasts from newborns and older patients differed namely in terms of nestin expression and also in the production of extracellular matrix components. We conclude that in vitro described properties of keratinocytes and fibroblasts in newborns could participate on the almost scar-less wound healing in earliest neonatal period.

Influence of primary septal cartilage reposition on development of the nose in UCLP.

The preceding study (Smahel, 1987) showed that after the abolishment of osteoplasty and introduction of primary reposition of nasal septum base in the 1970's the nasal deviation and asymmetry of nasal wing length in patients with unilateral cleft lip and palate had been reduced. The present study shows that this reduction continues after the introduction of total septum reposition. The deviation of septal base (columella) from the median plane and asymmetry in nostril position is reduced as well. The surgeon's experience however is the decisive factor determining the final shape of the nose.

The multidisciplinary care of cleft defects in the Prague Department of Plastic Surgery has a long tradition. The authors describe the team care of patients including the timing of the surgery as well as the conservative therapy.

Surface facial modelling and allometry in relation to sexual dimorphism.

Sexual dimorphism is responsible for a substantial part of human facial variability, the study of which is essential for many scientific fields ranging from evolution to special biomedical topics. Our aim was to analyse the relationship between size variability and shape facial variability of sexual traits in the young adult Central European population and to construct average surface models of adult males and females. The method of geometric morphometrics allowed not only the identification of dimorphic traits, but also the evaluation of static allometry and the visualisation of sexual facial differences. Facial variability in the studied sample was characterised by a strong relationship between facial size and shape of sexual dimorphic traits. Large size of face was associated with facial elongation and vice versa. Regarding shape sexual dimorphic traits, a wide, vaulted and high forehead in combination with a narrow and gracile lower face were typical for females. Variability in shape dimorphic traits was smaller in females compared to males. For female classification, shape sexual dimorphic traits are more important, while for males the stronger association is with face size. Males generally had a closer inter-orbital distance and a deeper position of the eyes in relation to the facial plane, a larger and wider straight nose and nostrils, and more massive lower face. Using pseudo-colour maps to provide a detailed schematic representation of the geometrical differences between the sexes, we attempted to clarify the reasons underlying the development of such differences.
