Doubts of caregivers of children with cleft lip and palate on postoperative care after cheiloplasty and palatoplasty

Objective To identify the main doubts of caregivers of children with cleft lip and palate on postoperative care after cheiloplasty and palatoplasty. Method Cross-sectional study carried out in a reference hospital, between September and November 2012. The sample was composed of 50 individuals divided in two groups, of which 25 caregivers of children submitted to cheiloplasty, and 25 of children submitted to palatoplasty. The doubts were identified by an interview applied during the preoperative nursing consultation and were then categorized by similarity. Descriptive statistics was used for analysis of the outcomes. Results Concerning cheiloplasty, the doubts were related to feeding (36%), hygiene and healing (24% each), pain and infection (8% each). With regard to palatoplasty, the doubts were related to feeding (48%), hygiene (24%), pain (16%), bleeding (8%) and infection (4%). Conclusion The study evidenced the concern of caregivers in relation to feeding and care of the postoperative wound.

Evaluation of fecal microorganisms of children with cleft palate before and after palatoplasty

This study isolated and quantified intestinal bacteria of children with cleft palate before and after palatoplasty. A prospective study was conducted from May 2007 to September 2008 on 18 children with cleft palate, aged one to four years, of both genders, attending a tertiary cleft center in Brazil for palatoplasty, to analyze the effect of surgical palate repair on the concentration of anaerobes Bacteroides sp, Bifidobacterium sp and microaerophiles Lactobacillus sp in feces of infants with cleft palate before and 24 hours after treatment with cefazolin for palatoplasty. There was significant reduction of Lactobacillus sp (p < 0.002), Bacteroides sp (p < 0.001) and Bifidobacterium sp (p = 0.021) after palatoplasty, revealing that surgery and utilization of cefazolin significantly influenced the fecal microbiota comparing collections before and after surgery. However, due to study limitations, it was not possible to conclude that other isolated factors, such as surgical stress, anesthetics and other medications used in palatoplasty might have a significant influence on the microbiota. Considering the important participation of the intestinal microbiota on both local and systemic metabolic and immunological activities of the host, professionals should be attentive to the possible influence of these changes in patients submitted to cleft repair.

Influence of palatoplasty on occlusion of patients with isolated cleft palate

OBJECTIVE: This study compared the dental arch morphology of adult patients with isolated cleft palate in order to verify the influence of palatoplasty on occlusion. METHODS: Cast models of 77 patients, 30 males and 47 females, with an average age of 21 years and no syndromes were taken. They were in the permanent dentition and had not undergone orthodontic treatment. The sample was divided into non-operated and operated patients, the latter having been submitted to palatoplasty at a mean age of 2.2 years. RESULTS: Almost 80% of the sample exhibited sagittal discrepancies in the inter-arch relationship, with a Class II malocclusion prevailing (59.74%) followed by Class III (20,78%), regardless of palatoplasty. Transverse analysis showed a 23% incidence of posterior crossbite also not influenced by palatoplasty. Intra-arch relationship indicated that constriction and crowding on the upper arch were more frequent in the operated group (p=0.0238 and p=0.0002, respectively), showing an influence of palatoplasty on its morphology. The predominant morphological characteristics in patients with isolated cleft palate were a Class II malocclusion, upper dental arch constriction and upper and lower anterior crowding. CONCLUSION: The influence of palatoplasty was restricted to constriction and crowding of the upper dental arch, with no interference from the extension of the cleft, except for the upper crowding, which occurred more in patients with complete cleft palates.

Dental Arch Relationships following Palatoplasty for Cleft Lip and Palate Repair

Palatal scarring is assumed to be a primary cause of facial growth derangement in cleft lip and palate. Evidence supporting this hypothesis is confounded by the clinical involvement of various surgeons, and therefore definitive conclusions are not possible. In this study, we investigated the dental arch relationship in two groups, Exposed (47 children; 11.2 yrs) and Unexposed (61 children; 11.2 yrs), with a unilateral cleft lip and palate operated on by the same surgeon. The technique of hard palate repair differed between the two groups. In the Exposed group, palatal bone of the non-cleft side only was left denuded, inducing scar formation. In the Unexposed group, a vomerplasty with tight closure of the soft tissues was applied. Three raters graded the dental arch relationship and palatal morphology using the EUROCRAN Index. The dental arch relationship in the Exposed group was less favorable than in the Unexposed group (p = 0.009). Palatal morphology in both groups was comparable (p = 0.323). This study demonstrates that reduction of denuded bony areas on the palate after palatal repair with a vomer flap had a favorable effect on the dental arch relationship. For palatal morphology, no effect of the type of palatal repair was found.

Cephalometric outcome of two types of palatoplasty in complete unilateral cleft lip and palate

In complete unilateral cleft lip and palate (CLP), a vomerplasty is assumed to improve midfacial growth because of the reduction in scarring in the growth-sensitive areas of the palate. Our aim, therefore, was to evaluate maxillofacial morphology after a modified Langenbeck technique or a vomerplasty in children with complete unilateral CLP who were operated on by a single surgeon. As part of a one-stage closure of complete unilateral CLP done during the first year of life, the technique for repair of the hard palate repair differed between the two groups. In the modified group (n=37, mean age 11 years) a modified von Langenbeck technique was used that resulted in denudation of the bony surface on the non-cleft side only. In the vomerplasty group (n=37, mean age 11 years) a vomerplasty was used to cover the palatal bone. Lateral cephalograms from both groups were compared using the Eurocleft protocol. Fourteen angular variables were measured and 2 ratios calculated. Skeletal morphology in the groups was comparable. Maxillary incisor inclination (ILs/NL angle) and interincisal angle (ILs/ILi) were better after vomerplasty (p=0.001 and 0.04, respectively) but soft tissue facial convexity (gs-prn-pgs) was less good after vomerplasty (p=0.009). However, there was no difference between the groups in the other variable that reflected facial convexity (gs-sn-pgs) (p=0.22). Modification of the palatoplasty had a limited effect on skeletal morphology in preadolescent children, but it resulted in better inclination of the maxillary incisors.

Nasolabial appearance after two palatoplasty types in cleft lip and palate.

BACKGROUND Facial appearance is important for normal psychosocial development in children with cleft lip and palate (CLP). There is conflicting evidence on how deficient maxillary growth may affect nasolabial esthetics. METHODS We retrospectively investigated nasolabial appearance in two groups, the Langenback (35 children; mean age 11.1 years; range: 7.9-13.6) and Vomerplasty (58 children; mean age 10.8 years; range: 7.8-14), who received unilateral CLP surgery by the same surgeon. The hard palate repair technique differed between the two groups. In the Langenback group, palatal bone on the non-cleft side only was left denuded, inducing scar formation and inhibiting maxillary growth. In the Vomerplasty group, a vomerplasty with tight closure of the soft tissues on the palate was applied. Thirteen lay judges rated nasolabial esthetics on photographs using a modified Asher-McDade's index. RESULTS Nasolabial esthetics in both groups was comparable (p > 0.1 for each nasolabial component). Inferior view was judged as the least esthetic component and demonstrated mean scores 3.18 (SD = 0.63) and 3.13 (SD = 0.47) in the Langenback and Vomerplasty groups, respectively. Mean scores for other components were from 2.52 (SD = 0.63) to 2.81 (SD = 0.62). Regression analysis showed that vomerplasty is related with slight improvement in the nasal profile only (coefficient B = -0.287; p = 0.043; R(2 ) = 0.096). CONCLUSIONS This study demonstrates that the use of vomerplasty instead of the Langenbeck technique is weakly associated with the nasolabial appearance among pre-adolescent patients with UCLP.

Caracterização da fala de indivíduos submetidos à palatoplastia primária

OBJETIVOS: Descrever as características de fala de indivíduos submetidos à palatoplastia primária; relacioná-las com tipo de fissura, técnica cirúrgica e idade na ocasião da cirurgia; e descrever as condutas fonoaudiológicas após a cirurgia. MÉTODOS: Estudo retrospectivo de 167 casos, de ambos os gêneros, com fissura labiopalatina, submetidos à palatoplastia primária. Foram coletadas informações relativas ao tipo de fissura, idade na palatoplastia, técnica cirúrgica, e as análises subjetivas sobre as características da fala, realizadas por fonoaudiólogas. RESULTADOS: Na avaliação perceptiva da fala após a cirurgia, encontrou-se inteligibilidade de fala alterada (46%), ressonância hipernasal (33%), articulações compensatórias (26%), emissão de ar nasal (14%), mímica facial (11%) e fraca pressão aérea intra-oral (8%). Na associação entre a ressonância e as articulações compensatórias com tipo de fissura, técnica cirúrgica e faixa etária, não houve diferença significativa. A conduta mais frequentemente tomada foi a de terapia fonoaudiológica (38%), para correção das articulações compensatórias e/ou outras alterações. CONCLUSÃO: A maioria dos indivíduos apresentou ressonância equilibrada ou hipernasalidade aceitável e ausência de articulações compensatória, independente do tipo de fissura, da técnica cirúrgica e da faixa etária, embora não tenha ocorrido diferença significativa. Dentre as condutas adotadas após a primeira avaliação pós-palatoplastia primária, a terapia fonoaudiológica foi a mais frequente.

Transsphenoidal meningoencephalocele associated with cleft lip and palate: challenges for diagnosis and surgical treatment

The aim of this study was to highlight the challenges for early diagnosis and the difficulties observed in surgical treatment of patients with transsphenoidal meningoencephalocele associated with cleft lip and/or palate. We evaluated six male patients treated over the course of 4 years. Five patients presented encephalic herniation with nonfunctional brain tissue; one of these presented herniation of the pituitary gland and cerebral ventricles. All the patients received surgical treatment for the cleft lip and/or palate. Only one patient underwent repair of the meningoencephalocele, via nasal endoscopy. There were no postprocedural clinical or surgical complications. The tendency is to avoid neurosurgery, opting for periodic follow-up with magnetic resonance imaging. In the presence of cleft palate, palatoplasty is essential to protect the meningoencephalocele.

Prospective Clinical Trial Comparing Outcome Measures Between Furlow and von Langenbeck Palatoplasties for UCLP

The goal of this prospective randomized clinical trial was to compare 2 cohorts of standardized cleft patients with regard to functional speech outcome and the presence or absence of palatal fistulae. The 2 cohorts are randomized to undergo either a conventional von Langenbeck repair with intravelar velarplasty or the double-opposing Z-plasty Furlow procedure. A prospective 2 x 2 x 2 factorial clinical trial was used in which each subject was randomly assigned to 1 of 8 different groups: 1 of 2 different lip repairs (Spina vs. Millard), 1 of 2 different palatal repair (von Langenbeck vs. Furlow), and 1 of 2 different ages at time of palatal surgery (9-12 months vs. 15-18 months). All surgeries were performed by the same 4 surgeons. A cul-de-sac test of hypernasality and a mirror test of nasal air emission were selected as primary outcome measures for velopharyngeal function. Both a surgeon and speech pathologist examined patients for the presence of palatal fistulae. In this study, the Furlow double-opposing Z-palatoplasty resulted in significantly better velopharyngeal function for speech than the von Langenbeck procedure as determined by the perceptual cul-de-sac test of hypernasality. Fistula occurrence was significantly higher for the Furlow procedure than for the von Langenbeck. Fistulas were more likely to occur in patients with wider clefts and when relaxing incisions were not used.

Palatoplastia com biomembrana natural de látex com polilisina 0,1% em cães com defeito palatino experimentalmente induzido

The palatoplasty is a correction surgery to restore the isolation between the oral and nasal cavity, avoid breath of food. There are many techniques to repair palatal defects, and the most used is mucoperiosteal flap. Grafts and prothesis, can be used too. Scientific works with Natural Latex Biomembrane with 0,1% Polylisine reveals properties like biocompatibility, improve and accelerate the cicatricial process, the stimulation of new vessels and organized tissue growth in different organs. Seven dogs were arranged in two groups and were submitted to experimental hard palate cleft. Five dogs received palatal repair with the natural latex biomembrane with 0,1% polylisine. Two animals did not receive any repair (control group) and the defect healing by second intention. After surgery, the groups were observed macroscopically and clinically to evaluate the results. The healling of cleft palate of group I was faster than control group, and this fact suggests that the biomembrane is an accelerator factor for cicatricial process.

Prevalence of oral habits in children with cleft lip and palate

This study investigated the prevalence of oral habits in children with clefts aged three to six years, compared to a control group of children without clefts in the same age range, and compared the oral habits between children with clefts with and without palatal fistulae. The sample was composed of 110 children aged 3 to 6 years with complete unilateral cleft lip and palate and 110 children without alterations. The prevalence of oral habits and the correlation between habits and presence of fistulae (for children with clefts) were analyzed by questionnaires applied to the children caretakers. The cleft influenced the prevalence of oral habits, with lower prevalence of pacifier sucking for children with cleft lip and palate and higher prevalence for all other habits, with significant association (P < 0.05). There was no significant association between oral habits and presence of fistulae (P > 0.05). The lower prevalence of pacifier sucking and higher prevalence of other oral habits agreed with the postoperative counseling to remove the pacifier sucking habit when the child is submitted to palatoplasty, possibly representing a substitution of habits. There was no causal relationship between habits and presence of palatal fistulae

Retrospective evaluation of postoperative nasotracheal tubes for oxygen supplementation in dogs following surgery for brachycephalic syndrome: 36 cases (2003-2007)

OBJECTIVE: To assess the utility of nasotracheal tubes in postoperative oxygen supplementation in dogs following corrective surgery for brachycephalic syndrome. DESIGN: Retrospective study 2003-2007. SETTING: University teaching hospital. ANIMALS: Thirty-six client-owned dogs that underwent corrective surgery for brachycephalic syndrome. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Medical records were reviewed for animals that underwent surgical interventions for brachycephalic syndrome including palatoplasty, ventriculectomy, and rhinoplasty. Data collected included signalment, presenting complaints, analgesic and surgical interventions, type of supplemental oxygen therapy, complications and mortality occurring during hospitalization. A nasotracheal tube (NTT) was placed in 20 dogs at the end of surgery; 16 dogs received other forms of oxygen supplementation (8) or no oxygen supplementation (8) during recovery. The total number of postoperative complications was similar in both groups (8/20 dogs with NTTs and 7/16 in those without NTTs). However, respiratory distress was observed in 5 dogs without NTTs but was not observed in any dog while an NTT was in place. One dog in each group died postoperatively. CONCLUSION: Placement of an NTT was found to be easy and may offer benefit in dogs with brachycephalic syndrome as a noninvasive means of delivering oxygen. The use of NTT may minimize severe postoperative morbidity, in particular by reducing postoperative respiratory distress.
