1/27. Bilateral congenital choanal atresia and absence of respiratory distress.

    Bilateral congenital choanal atresia is considered a lethal congenital malformation in an obligatory nasal breathing neonate. Described herein are two cases of bilateral choanal atresia associated with craniofacial anomalies who did not present respiratory distress in the neonatal period. Our first patient had a complete unilateral cleft lip which facilitated oropharyngeal respiration. The second patient presented wory distress in the neonatal period by providing an oropharyngeal airway. ( info)

2/27. Bimaxillary orthognathic surgery in a patient with long face: a case report.

    The primary characteristics of long face patients are gummy smile and/or anterior open bite. Consequently, correction of esthetic and functional problems are especially important for long face patients. Since orthodontic therapy alone is not sufficient to solve the problem, orthognathic surgical approach is indicated for these patients. In this report, orthognathic surgical therapy of a severe long face patient with similar findings was presented. Following clinical and cephalometric examination and preoperative orthodontic therapy, a Le Fort I osteotomy, a bilateral sagittal split osteotomy, and vertical and horizontal reduction genioplasties were performed. Alternative surgical therapies, complications, and the effects on the upper respiratory tract are also discussed. ( info)

3/27. Consequences of oral rehabilitation on dyskinesia in adults with Down's syndrome: a clinical report.

    The aim of this article is to demonstrate that the presence of orofacial dyskinesia is often owing to underlying facial dysmorphology in persons with Down's syndrome. A series of cases is presented where orofacial dyskinesia was successfully treated by therapy establishing occlusal stability. The diagnosis of dyskinesia owing to dysmorphology should be precluded before any link with the degree of intellectual disability or neurological deficit is presumed. A multidisciplinary approach may be necessary to diagnose and treat these patients. ( info)

4/27. Orthodontic treatment in handicapped children: report of four cases.

    Mentally and physically handicapped children show in the orofacial system motor-sensitivity disturbances and malocclusions of varying severity. These dysfunctions affect the breathing and speech ability and inhibit the food intake. Myotherapeutic exercises for strengthening of lip and tongue muscles and orthodontic treatment of the malocclusions help provide esthetic and functional improvements in these patients. The limited compliance necessitates a differentiated procedure during the diagnostic and therapeutic process and demands compromises in some cases. ( info)

5/27. Dental malocclusion and upper airway obstruction, an otolaryngologist's perspective.

    INTRODUCTION: This paper, through the presentation of eight case reports and a limited literature review, attempts to illustrate the negative effect that upper airway obstruction can have on developing dental occlusion and the positive effect that upper airway relief can have on the 'normalization' of various malocclusion patterns believed to be related to chronic obligate mouth breathing. OBJECTIVE: To study the effect of airway relief (usually through tonsillectomy and/or adenoidectomy) on various patterns of dental malocclusion. methods: Children coming to the office of the lead author (D.J.W.) found to be obligate mouth breathers and who also had dental malocclusion had Polaroid 'bite' pictures taken at the time of their initial visit. One year or more after their surgery for upper airway relief (tonsillectomy and adenoidectomy in these cases) a second 'bite' photograph was taken and compared to the first. RESULTS: In all cases selected in this study there was observed improvement in their dental occlusion within a year following surgery to improve their breathing. CONCLUSION: It is the opinion of the authors of this paper that upper airway obstruction may have a negative effect on the developing transitional dental occlusion and that eliminating the cause of upper airway obstruction can lead to 'normalization' of occlusion in such children. Further orthodontic corrective modalities may be required for optimal occlusal results. ( info)

6/27. Congenital salivary gland anlage tumor of the nasopharynx.

    OBJECTIVE: Nasal and upper respiratory tract obstruction in the neonatal period can result from a variety of conditions, and may present with variable symptoms. In the absence of dysmorphic features or other abnormalities, causes of nasal obstruction may be difficult to differentiate on initial examination. We report an unexpected and potentially life-threatening condition arising during the work-up of this common neonatal complaint. DESIGN: Case report with literature review. RESULTS: A male neonate presented with complaints of nasal obstruction and feeding difficulties. A common diagnostic approach to neonatal nasal obstruction was performed, resulting in an unexpected and potentially life-threatening, albeit curative, result. Cannulation of the nasal cavity to rule out choanal atresia resulted in a burst of bleeding from the nose and mouth. A finger sweep of the oropharynx produced a dislodged mass lesion. pathology revealed a salivary gland anlage tumor of the nasopharynx. CONCLUSIONS: The diagnosis of a nasopharyngeal mass lesion should be considered in neonates with nasal obstructive symptoms. It is wise to place an index finger in the oropharynx when passing catheters to rule out choanal atresia to feel a dislodged mass lesion before it can become an airway foreign body. Should passage of nasal catheters result in bleeding and/or respiratory distress, the possibility of a displaced mass lesion must be considered immediately to institute prompt intervention. ( info)

7/27. Long-term outcome of skeletal Class II Division 1 malocclusion treated with rapid palatal expansion and Kloehn cervical headgear.

    The treatment of a patient with a skeletal Class II Division 1 malocclusion, with excessive overjet, complete overbite, airway obstruction, and severe arch length deficiency in the mandibular dental arch, is presented. The maxilla was narrow compared with the mandible, and the posterior teeth were compensated, with the maxillary teeth inclined buccally and the mandibular teeth inclined lingually. The palatal vault was extremely high. Treatment included rapid palatal expansion to correct the transverse maxillary deficiency and Kloehn cervical headgear to correct the anteroposterior skeletal discrepancy. Long-term stability (12-year follow-up) is reported. ( info)

8/27. Craniofacial morphology in an unusual case with nasal aplasia studied by roentgencephalometry and three-dimensional CT scanning.

    OBJECTIVE: To examine the three-dimensional morphology of internal structures of the craniofacial region and present the orthodontic problems in an unusual case with nasal aplasia. PATIENT: The patient was an 11.5-year-old boy with aplasia of the nose and nasal cavity with extremely constricted nasopharyngeal airway. He did not have mental or somatic retardation. The patient had dacryostenosis. The morphology of the craniofacial structures was characterized by absence of septal structures, including cribriform plate, perpendicular plate of ethmoid bone, vomer, and septal cartilage; bony hypotelorism; midface hypoplasia; short and retrognathic maxilla with Class III jaw relationship; average mandibular plane angle; high arched palate; severe anterior open bite with bilateral posterior crossbites; and dental anomalies (agenesis of four maxillary permanent teeth, microdontia, taurodontism, and short roots). Thus, the patient had characteristic dentofacial phenotype, which might be caused by a combination of the primary anomaly and the functional disturbances secondary to the nasal obstruction. ( info)

9/27. "Moebius syndrome": a case report.

    Moebius syndrome is an extremely rare disorder characterized by a lifetime facial paralysis, involving sixth and seventh cranial nerves with malformations of orofacial structures and the limbs. In this case, an 8 year old girl with Moebius syndrome is presented, clinical findings are described and management aspects are discussed. Early dental evaluation and parental counselling as a part of preventive dental regimen can go a long way in providing complete psychosocial rehabilitation for such physically disabled children.

10/27. Class II correction in a severe hyperdivergent growth pattern, bilateral open bite and oral compromise.

    Severe vertical growth pattern and open bites are frequent problems the orthodontist must resolve but require a proper diagnosis, treatment plan, timing, and mechanotherapy to be properly treated. A case report with these problems is presented. ( info)
