Correção da deficiência transversa da maxila por meio da expansão rápida da maxila cirurgicamente assistida

Fundamentation: The correction of maxillary transverse deficiencies involves orthodontic and surgical procedures that can be performed before or after skeletal maturity. The surgically assisted rapid maxillary expansion (SAR ME) is performed by osteotomies through the lateral walls of the maxilla, zygomatic and canines buttresses, palatal and pterygomaxillary sutures, causing the maxillary disjunction. Followed by activation of the expander to the desired over-expansion in order to correct intercuspal later. Objective: The purpose of this study was to discuss the issues involved in the diagnosis of maxillary atresia, SAR ME indications, as well as surgical technique, through a case study. Methods: The male patient, 19 years old, had severe transverse maxillary deficiency with facial pattern III , Class III , with great lip incompetence. The patient underwent general anesthesia in a hospital environment, the osteotomies was done according to the technique described by Epker and Wolford (1980). Postoperatively, the patient underwent activations daily for 15 days and after 6 months, the orthodontist installed fixed orthodontic appliance to prepare the patient to orthognathic surgery later. Conclusion: The diagnosis by clinical evaluation and models study is essential for the indication of SAR ME and this procedure provides good predictability in the correction of transverse deficiency, with minimal morbidity.

Atresia maxilar em adultos: simplificação da técnica cirúrgica

A expansão rápida da maxila cirurgicamente assistida (ERMCA) é realizada por meio de osteotomias nos pilares da maxila e na sutura palatina mediana, promovendo a correção da deficiência transversa da maxila. Técnicas menos invasivas foram descritas, visando à realização desses procedimentos sob anestesia local, eliminando os custos de internação hospitalar e trazendo maior conforto aos pacientes. A proposta deste trabalho foi discutir os aspectos envolvidos na simplificação da técnica da ERMCA sob anestesia local por meio do relato de caso clínico-cirúrgico de paciente com 27 anos de idade. Conclui-se que o diagnóstico por meio da avaliação clínica e dos modelos de estudo é essencial para a indicação da ERMCA e esse procedimento proporciona boa previsibilidade na correção da deficiência transversal, com mínima morbidade. Além disso, a utilização de uma técnica minimamente invasiva é efetiva no tratamento de maxilas atrésicas, com índices de recidiva semelhantes aos das técnicas mais invasivas.

Prótese de palato em sujeitos com disfunção velofaríngea: expectativa e ansiedade

Cleft lip and palate (CLL) is a very common craniofacial anomaly. The cleft is usually corrected with surgery which may fail resulting in velopharyngeal dysfunction (VPD). The use of palatal prosthesis is an alternative treatment for correcting both, CLP and VPD. This study evaluated anxiety symptoms expectations of subjects of both genders, with velopharyngeal dysfunction, referred to palatal prosthesis program for VPD treatment. In this cross sectional and descriptive study 30 subjects with velopharyngeal dysfunction, aged 15 to 64 years old (mean age of 28) were interviewed at the Hospital for Rehabilitation of Craniofacial Anomalies (HRAC). All subjects referred to the palatal prosthesis program at HRAC in the year of 2005 were considered for participation in the study but only the first 30 candidates were included. A questionnaire addressing expectation elaborated by the researcher and the Beck Scale on anxiety were used. All subjects showed expectation regarding speech modification. Changes in professional and affective aspects of their lives after changes in speech were obtained with palatal prosthesis were the most reported expectations. Subjects’ age and gender influenced anxiety levels significantly which were minimum across subjects. High levels of expectation were more frequent than anxiety in the sample population.

Psychosocial and clinical predictors of retention in outpatient alcoholism treatment

Objective: One of the factors associated with low rates of compliance in the treatment for alcoholism seems to be the intensity of craving for alcohol. This study aimed to evaluate the associations between alcohol craving and biopsychosocial addiction model-related variables and to verify whether these variables could predict treatment retention. Methods: The sample consisted of 257 male alcoholics who were enrolled in two different pharmacological trials conducted at the Universidade de Sao Paulo in Brazil. Based on four factors measured at baseline - biological (age, race, and family alcoholism), psychiatric (depression symptoms), social (financial and marital status), and addiction (craving intensity, severity of alcohol dependence, smoking status, drinking history, preferential beverage, daily intake of alcohol before treatment) - direct logistic regression was performed to analyze these factors' influence on treatment retention after controlling for medication groups and AA attendance. Results: Increasing age, participation in Alcoholics Anonymous groups, and beer preference among drinkers were independently associated with higher treatment retention. Conversely, higher scores for depression increased dropout rates. Conclusion: Health services should identify the treatment practices and therapists that improve retention. Information about patients' characteristics linked to dropouts should be studied to render treatment programs more responsive and attractive, combining pharmacological agents with more intensive and diversified psychosocial interventions.

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

High dosage folic acid supplementation, oral cleft recurrence and fetal growth

Objectives: To evaluate the effects of folic acid supplementation on isolated oral cleft recurrence and fetal growth. Patients and Methods: The study included 2,508 women who were at-risk for oral cleft recurrence and randomized into two folic acid supplementation groups: 0.4 and 4 mg per day before pregnancy and throughout the first trimester. The infant outcome data were based on 234 live births. In addition to oral cleft recurrence, several secondary outcomes were compared between the two folic acid groups. Cleft recurrence rates were also compared to historic recurrence rates. Results: The oral cleft recurrence rates were 2.9% and 2.5% in the 0.4 and 4 mg groups, respectively. The recurrence rates in the two folic acid groups both separately and combined were significantly different from the 6.3% historic recurrence rate post the folic acid fortification program for this population (p = 0.0009 when combining the two folic acid groups). The rate of cleft lip with palate recurrence was 2.9% in the 0.4 mg group and 0.8% in the 4 mg group. There were no elevated fetal growth complications in the 4 mg group compared to the 0.4 mg group. Conclusions: The study is the first double-blinded randomized clinical trial (RCT) to study the effect of high dosage folic acid supplementation on isolated oral cleft recurrence. The recurrence rates were similar between the two folic acid groups. However, the results are suggestive of a decrease in oral cleft recurrence compared to the historic recurrence rate. A RCT is still needed to identify the effect of folic acid on oral cleft recurrence given these suggestive results and the supportive results from previous interventional and observational studies, and the study offers suggestions for such future studies. The results also suggest that high dosage folic acid does not compromise fetal growth

Complicações após expansão de maxila cirurgicamente assistida

Introduction: The treatment of adult transverse maxillary deficiency is the surgically assisted maxillary expansion. Several surgical techniques have been described for this and complications have been related to these procedures. Objective: the aim of this study was evaluate the incidence of complications associated with surgically assisted maxillary expansion. Material and method: 33 individuals undergone surgically assisted maxillary expansion by subtotal Le Fort I osteotomy with a step in the zygomatic-maxillary buttress and associated to pterigomaxillary disjunction and osteotomy of intermaxillary suture. Operative complications, post-operative complications and the distance between the upper teeth were recorded. Result: 12 men and 21 women with an average age of 24.64 years undergone the procedure. The interdental distances increased from preoperative to 2 months post?operative time. The prevalent complications were sinusitis (6%) and teeth displacement and inclination (6%). Conclusion: Surgically assisted maxillary expansion is an effective and low morbidity procedure to treat transverse maxillary deficiency in adults.

Evaluation of facial esthetics in rehabilitated adults with complete unilateral cleft lip and palate

Objectives. The aim of this study was to evaluate the facial esthetics of White-Brazilian adults with complete unilateral cleft lip and palate (UCLP) rehabilitated at a single center. Design. 30 patients (13 females; 17 males; mean age of 24.0 years), rehabilitated at a single center, were photographed and evaluated by 25 examiners, 5 orthodontists, and 5 plastic surgeons dealing with oral clefts, 5 orthodontists and 5 plastic surgeons with no experience in the cleft treatment, and 5 laymen. Their facial profiles were classified into esthetically unpleasant, esthetically acceptable, and esthetically pleasant. Results. Orthodontists dealing with oral clefts classified the majority of the sample as esthetically pleasant. Plastic surgeons dealing with oral cleft, orthodontists, and plastic surgeons without experience with oral clefts classified most of the sample as esthetically acceptable. Laymen evaluation also considered the majority of the sample as esthetically acceptable. Conclusions. The facial profiles of rehabilitated adults with UCLP were classified mostly as esthetically acceptable, with variations among the categories of examiners. The examiners dealing with oral clefts gave higher scores to the facial esthetics when compared to professionals without experience in oral clefts and laypersons, probably due to their knowledge of the limitations involved in the rehabilitation process

Auditory complaints and audiologic assessment in children with surgically repaired cleft lip and palate

Introduction: At the initial consultation, the speech-language pathologist and audiologist may consider possible diagnostic hypotheses based on the child's history and the parents' complaint. Aim: To investigate the association of hearing complaints with the findings obtained in the conventional audiologic assessment in children with cleft lip and palate. Retrospective study. Methods: We analyzed medical charts of 1000 patients with cleft lip and palate who underwent surgical repair between 1988 and 1995 at a mean age of 6 years 8 months. We excluded charts with records of inconsistent audiological responses and charts with missing data for any of the audiologic evaluations considered. Thus, the sample consisted of 393 records. Results: Two hundred thirty-nine patients presented hearing loss in one or both ears, but only 3.8% reported hearing complaints. The most frequent were otorrhea followed by otalgia. There was no statistical significance between the complaint and gender (p = 0.26) nor between the complaint and hearing loss (p = 0.83). Conclusion: This study showed no association between the hearing complaint and the conventional audiologic assessment

Intranasal tooth and associated rhinolith in a patient with cleft lip and palate

We report the case of a 9-year-old girl who presented with a complaint of a malodorous bloody discharge from the left naris. The patient had previously undergone a complete repair of left-sided cleft lip and palate. Clinical examination revealed hyperplasia of the nasal mucosa on the left side. X-ray examination of the nasal cavity demonstrated a radiopaque structure that resembled a tooth and a radiopaque mass similar to an odontoma that was adherent to the root of the suspected tooth. With the patient under general anesthesia, the structure was removed. On gross inspection, the structure was identified as a tooth with a rhinolith attached to the surface of its root. Microscopic examination revealed normal dentin and pulp tissue. A nonspecific inflammatory infiltrate was observed around the rhinolith, and areas of regular and irregular mineralization were seen. Some mineralized areas exhibited melanin-like brownish pigmentation. Areas of mucus with deposits of mineral salts were also observed. Rare cases of an intranasal tooth associated with a rhinolith have been described in the literature. We believe that this case represents only the second published report of an intranasal tooth associated with a rhinolith in a patient with cleft lip and palate

Aesthetic analysis of an implant-supported denture at the cleft area

Objective: To evaluate the aesthetics of an implant-supported denture at the cleft area, comparing the peri-implant tissues and prosthetic crown with the contralateral tooth. Settings: Hospital for Rehabilitation of Craniofacial Anomalies, Bauru, São Paolo, Brazil. Patients: A total of 39 individuals of both genders, with complete unilateral cleft lip and palate, who received secondary alveolar bone graft and were rehabilitated with single implant-supported dentures at the area of the missing maxillary lateral incisor after completion of orthodontic treatment. Interventions: The following parameters were analyzed in follow-up sessions: length and width of prosthetic crown and contralateral tooth, characteristics of implants, filling of interproximal space by the papilla, and smile height of the patients. Results: The implant-supported prosthetic crowns were longer than the contralateral tooth (p < .001). Among the 78 papillae analyzed, 29 (37.17%) received a score of 3; 32 (41.02%) papillae had a score of 2; and 17 (21.79%) received a score of 1. Concerning the smile height, among the 39 patients analyzed, 23 (56.41%) had a medium smile, 15 (38.46%) had a high smile, and two (5.12%) presented a low smile. Conclusion: The use of dental implants to rehabilitate the edentulous cleft area is an excellent option. However, adequate evaluation of the bone quantity and quality, positioning and shape of adjacent teeth, smile height, and patient expectations should be considered to achieve success and avoid aesthetic deformities such as elongated teeth and absence of gingival papillae.

Effect of rapid maxillary expansion on the dimension of the nasal cavity and on facial morphology assessed by acoustic rhinometry and rhinomanometry

OBJECTIVE: To assess the effects of rapid maxillary expansion on facial morphology and on nasal cavity dimensions of mouth breathing children by acoustic rhinometry and computed rhinomanometry. METHODS: Cohort; 29 mouth breathing children with posterior crossbite were evaluated. Orthodontic and otorhinolaryngologic documentation were performed at three different times, i.e., before expansion, immediately after and 90 days following expansion. RESULTS: The expansion was accompanied by an increase of the maxillary and nasal bone transversal width. However, there were no significant differences in relation to mucosal area of the nose. Acoustic rhinometry showed no difference in the minimal cross-sectional area at the level of the valve and inferior turbinate between the periods analyzed, although rhinomanometry showed a statistically significant reduction in nasal resistance right after expansion, but were similar to pre-treatment values 90 days after expansion. CONCLUSION: The maxillary expansion increased the maxilla and nasal bony area, but was inefficient to increase the nasal mucosal area, and may lessen the nasal resistance, although there was no difference in nasal geometry. Significance: Nasal bony expansion is followed by a mucosal compensation.
