Total Obturation of Velopharynx for Treatment of Velopharyngeal Hypodynamism: Case Report

A child with microdeletion at 22q11.21 was referred to a craniofacial center due to hypernasality, unintelligible speech, and bifid uvula. Velopharyngeal dysfunction remained after surgical repair of submucous cleft palate and speech therapy. A prosthetic-behavioral treatment approach involving total obturation of the velopharynx was successfully implemented for management of velopharyngeal hypodynamism.

Management of an Unusual Presentation of Ascher Syndrome

Ascher syndrome is defined by the association between double lip, blepharochalasis, and nontoxic goiter. Because it is a rare disease, it is most often misdiagnosed, despite its implications for quality of life. We report a variation of an incomplete type of Ascher syndrome affecting the upper lip, upper eyelids, and lateral canthi of a young male patient. The surgical management, follow-up, and a brief overview of the syndrome are described. The results presented show an aesthetic and functional improvement of the facial deformities.

New treatment for frontal sinus hypertrophy

A new treatment of frontal sinus hypertrophy is described. The anterior wall is removed, inverted, and attached again. The resulting depression is filled with bone dust. Details are discussed, and a case is presented.

ALGIAS CRANIOFACIAIS - UM ROTEIRO PARA O EXAME FISICO DIRIGIDO

Craniofacial pain is a frequent challenge for the physician anamnesis with the goal to obtain specific and useful information about symptoms in craniofacial pain. It can be improved by identifying aching points. In the article, the authors present a practical and specific schedule for physical examination to be applied in patients with chronic pain. This specific schedule, which has proved useful in detecting the exact anatomic sites of pain, has a sequence ordered which includes palpation and inspection of muscles, nerves and arteries.

Cranioplasty: The autograft option

We present our clinical experience in cranioplasty with autograft as follows: conchal cartilage for losses up to 2 cm2, outer table grafts for defects up to 100 cm2, and, for larger defects still, split rib grafts, which may be combined with outer table grafts. We conclude that autograft is superior to alloplastic material in cranioplasty.

New option for anterior traction of the face by using a cervical collar

This case required anteroposterior traction of the maxilla. Once none of the traditional methods could be used because of the lack of support in the chin and in the frontal region. Thus, we opted to use a cervical collar.

Dosimetry and cost of imaging osseointegrated implants with film-based and computed tomography

Thermoluminescent dosimeters were used to measure radiation doses at craniofacial sites in a tissue-equivalent phantom during film-based multidirectional tomography with the Tomax Ultrascan (Incubation Industries, Ivyland, Pa.) and during computed tomography with the Elscint Excel 2400 (Elscint Corp., Tel Aviv, Israel). Mean absorbed doses for presurgical mandibular and maxillary canine and molar implant assessments were converted to equivalent doses, which were then multipied by published weighting factors and summed to give effective doses. The computed tomgraphy device consistently delivered higher doses than the Tomax Ultrascan to all anatomic locations; the differences were most pronounced when only one or two implant sites were evaluated. The reasons for the dose disparities are considered both anatomically and procedurally. A survey of examination cost revealed film-based multidirectional tomography to be less expensive than computed tomography.

Treatment Effects Produced by Fränkel Appliance in Patients with Class II, Division 1 Malocclusion

The purpose of this investigation was to evaluate the dentoalveolar and skeletal cephalometric changes produced by the Fränkel appliance in individuals with a Class II, division 1 malocclusion. Lateral cephalograms of 44 patients of both sexes were divided in two groups of 22 each. The control group was comprised of untreated Class II children with an initial mean age of eight years and seven months who were followed without treatment for a period of 13 months. The Fränkel group had an initial mean age of nine years and was treated for a mean period of 17 months. Lateral cephalometric headfilms of each patient were obtained at the beginning and end of treatment. The Fränkel appliance produced no significant changes in maxillary growth during the evaluation period, while a statistically significant increase in mandibular length was observed. The maxillomandibular relationship improved mostly because of an increase in mandibular length. In addition, there were no statistically significant differences in the craniofacial growth direction between the Fränkel and the control group, both showing a slight downward rotation of the palatal plane. The Fränkel appliance produced a labial tipping of the lower incisors and a lingual inclination of the upper incisors as well as a significant increase in mandibular posterior dentoalveolar height. It was concluded that the main effects of the Fränkel appliance during this time period were mostly dentoalveolar with a smaller but significant skeletal mandibular effect.

Pediatras e os distúrbios respiratórios do sono na criança

OBJECTIVES. assessment of opinions and practices of pediatricians concerning sleep-disordered breathing (SDB) in children. Methods. randomly 516 pediatricians were selected in the state of São Paulo, Brazil. A survey mailed to them included questions regarding: their professional profile, knowledge about SDB in childhood, opinions and practices for diagnosis and treatment of these diseases. RESULTS. 112 anonymous completed surveys were returned (21.7%). The teaching of SDB during medical school and pediatric residency training was considered unsatisfactory respectively by 65.2% and 34.8% of the pediatricians. Forty-nine respondents (43.8%) rated their knowledge about SDB in children as regular, 39 (34.8%) as good and 17 (15.2%) as unsatisfactory. The most important sleep-related questions were: mouth breathing, breathing pauses, sleep amount, excessive daytime sleepiness and nocturnal wheezing. Clinical aspects regarded as the most significant for suspecting obstructive sleep apnea syndrome (OSAS) were: breathing pauses, adenoid hypertrophy, mouth breathing, craniofacial anomaly and snoring. The most frequent practices for evaluation of OSAS in children were: cavum radiography with referral to an otorhinolarnygologist (25%) and nocturnal pulse oximetry (14.2%). Only 11.6% of pediatricians recommended overnight polysomnography and 4.5%, nap polysomnography. The most effective practices for SDB were considered to be: adenoidectomy and adenotonsillectomy, parents counseling, weight loss and sleep hygiene. CONCLUSIONS. there is a gap between research on SDB in childhood and pediatric practice. © 2006 Associação Médica Brasileira.

Zygomatic bone: Anatomic bases for osseointegrated implant anchorage

Purpose: The aim of the present study was to evaluate zygomatic bone thickness considering a possible relationship between this parameter and cephalic index (Cl) for better use of Cl in the implant placement technique. Materials and Methods: Cl was calculated for 60 dry Brazilian skulls. The zygo matic bones of the skulls were divided into 13 standardized sections for measurement. Bilateral measurements of zygomatic bone thickness were made on dry skulls. Results: Sections 5, 6, 8, and 9 were appropriate for implant anchorage in terms of location. The mean thicknesses of these sections were 6.05 mm for section 5, 3.15 mm for section 6, 6.13 mm for section 8, and 4.75 mm for section 9. In only 1 section, section 8, did mean thickness on 1 side of of the skull differ significantly from mean thickness on the other side (P <.001). Discussion: For the relationship between quadrant thick ness and Cl, sections 6 and 8 varied independently of Cl. Section 5 associated with brachycephaly, and section 9 associated with subbrachycephaly, presented variations in the corresponding thickness. Conclusion: Based on the results, implants should be placed in sections 5 and 8, since they presented the greatest thickness, except in brachycephalic subjects, where thickness was greatest in section 5, and in subbrachycephalic subjects, where thickness was greatest in section 9. Cl did not prove to be an appropriate parameter for evaluating zygomatic bone thickness for this sampling.

Familial malignant osteopetrosis in children: A case report

The clinical, radiological, pathological and laboratory findings of two brothers with autosomal recessive malignant osteopetrosis are presented. Our findings are similar to characteristics previously reported in the literature about patients with osteopetrosis. The 6-year-old male patient was pale and had petechiae on his arms and legs. He also had macrocephalia, splenomegaly, severe pancytopenia, genu valgus, hypocalcemia, amaurosis, cessation of physical development, generalized bone sclerosis and recurrent infections with a history of multiple incidences of acute otitis media. Generalized bone sclerosis and irregular sclerosis of the maxilla and mandible were seen on radiographs. The oral mucosa was apparently normal but permanent tooth eruption was delayed although there was early loss of deciduous teeth. The recommended treatment was blood transfusion and therapy with antibiotics when necessary; a bone marrow transplant was not possible due to lack of a compatible donor.

Anoftalmia congênita clínica - alterações oculares e sistêmicas associadas

Purpose: To describe alterations observed in patients with congenital clinical anophthalmia and the occurrence of association with other ocular and extra ocular abnormalities. Methods: An observational retrospective study was conducted evaluating 12 patients with congenital clinical anophthalmia at Faculdade de Medicina de Botucatu-UNESP, between 1992 and 2005. In those patients it was observed the ocular abnormalities, severity, laterality, follow-up and to systemic abnormalities associated. The congenital clinical anophthalmia have been associated to major severity abnormalities extra-oculars, mainly when the anophthalmia was bilateral, such agenesis of corpus callosum, others craniofacial anomalies and cardiac defects. In the cases unilateral, the alteration associated more frequently was the facial asymmetry, showing the direct correlation between anophthalmos and development of orbit and face. Conclusion: There was relation between congenital clinical anophthalmia and ocular abnormally and extra-ocular abnormally. Patients with bilateral anophthalmos disease have more severe alterations. anophthalmia congenital attends a course with abnormalities of development of the face.

Ossificação da sutura palatina mediana após o procedimento de expansão rápida da maxila: Estudo radiográfico

Objective: the current study aims at following up radiographically the evolution of the midpalatal suture during the expansion procedure since the opening of the suture until bone formation. Methods: the sample comprised 38 patients in the mixed dentition stage submitted to the rapid palatal expansion protocol of the Hospital for Rehabilitation of Craniofacial Anomalies. Results: it was observed an individual variation on the period of bone ossification of the midpalatal suture, which justifies the radiographic follow-up as determinant for the appliance removal. Due to long-term post-treatment stability, the expander should be removed after the new suture is completely formed. Conclusions: the findings show that it is necessary more than three months for the complete reorganization of the midpalatal suture during the passive phase of the rapid palatal expansion.

Perfil de usuários de AASI com fissura labiopalatina

Cleft palates cause alterations in palate and lip structures, and it may also cause hearing loss because of recurrent otitis media. The appropriate treatment is controversial. It may include the prescription of antibiotics and insertion of a ventilation tube, or even otorhinolaryngological and audiological assistance, and hearing rehabilitation, with the use of an individual sound amplifier aid (ISAA). Aim: To characterize the profile of individuals with cleft palate and hearing loss, users of ISAA are assisted by the center of otorhinolaryngology and speech therapy of a hospital specialized in craniofacial anomalies and hearing impairment. Retrospective Study. Material and Methods: Retrospective analysis of 131 charts of patients with corrected cleft palate and hearing loss, fitted with ISAA by the center abovementioned. Results: The sample (n=131) was characterized by a prevalence of females (53%), unilateral incisive transforaminal cleft (27%), presence of associated anomalies (51%), history of alterations of the middle ear (56%) and surgery intervention (56%). Conclusion: The general profile of the individuals with cleft palate and hearing loss, fitted with ISAA, was characterized by the predominance of cleft lip and palate, positive history of middle ear alterations, surgery intervention and bilateral sensorineural hearing loss. © Revista Brasileira de Otorrinolaringologia.
