A new removable appliance design is presented which offers the possibility of significant palatal movement of the maxillary incisor roots and which is capable of producing marked changes in the position of the root apices. Heavy extra-oral forces may be applied through the appliance to the entire maxilla to orthopaedically change the facial growth pattern and ameliorate the Skeletal II problem, with the torquing movements being carried out concurrently. A second phase of Edgewise treatment, often with directly bonded transparent plastic brackets, is then carried out to complete the correction. This stage is much reduced in complexity and may be confined to alignments and detailing of the occlusion over a relatively short period of time.

Cephalometric Study

Introduction: Great emphasis has been given to the evaluation of sagittal apical base relationship in orthodontic diagnosis and treatment planning. The prediction of magnitude and direction of facial growth based on sagittal relationship will help in orthodontic treatment with growth modification. The objective of the study is to assess the growth pattern in skeletal Class I malocclusion. Materials and Method: 104 subjects (52 male and 52 female) with the age between 18-30 years with Class I skeletal relation was selected from lateral cephalograms of patients visiting the Department of Orthodontics, Kantipur Dental College. The ANB angle was measured to assess the sagittal jaw relationship and the Jarabak’s ratio to access the growth pattern. Descriptive statistics were calculated for each parameter. Pearson’s test was done to evaluate the correlation between the parameters. Independent t-test was done to compare Anterior Facial height (AFH), Posterior Facial Height (PFH) and Jarabak’s ratio between male and female subjects. Result: Among the total subjects with skeletal Class I malocclusion; hyperdivergent growth pattern was least (10.57%), followed by normodivergent (18.26%) and hypodivergent growth pattern (71.15%). Mean Jarabak’s ratio for hyperdivergent, normodivergent and hypodivergent growth pattern were 58.65±1.94, 63.98±0.85 and 69.98±4.13 respectively. Very strong correlation was found between AFH and PFH in hyperdivergent (r = 0.821) and normodivergent group (r =0.978). Strong correlation was found in hypodivergent group between AFH and PFH (r =0.743). Also, strong correlation was found in hypodivergent group between PFH and Jarabak’s ratio (r =0.643). Conclusion: Hypodivergent growth pattern was the dominant growth pattern in skeletal Class I malocclusion. PFH influenced the determination of Jarabak’s ratio more than the AFH in hypodivergent growth pattern. Hypodivergent growth pattern is correlated with large SNB angle.

Introduction. The Herbst device is widely used for correction of class II malocclusions; however, most of the researches carried out on the Herbst appliance in literature do not take into account patients with a different mandibular divergence. The aim of this study was to investigate the effects of Herbst on dental and skeletal structures and to evaluate possible influence of vertical facial growth patterns. Methods. A retrospective study was conducted on lateral cephalograms of 75 growing patients (mean age: 9.9 ± 1.9 years) with class II malocclusion treated with Herbst. Subjects were divided into 3 groups using the mandibular divergence index (SN and GoMe angle). Cephalometric parameters were evaluated using the modified SO (sagittal occlusion) Pancherz’s analysis. A statistical analysis was conducted to evaluate differences among groups using ANOVA. Results. Our study showed differences in response to treatment depending on patient’s facial vertical growth pattern. Cranial base angle and mandibular rotation were significantly different (p<0.05) between hypodivergent patients and normodivergent patients and between hypodivergent and hyperdivergent subjects. Conclusion. Hypodivergent patients increased their mandibular divergence during treatment to a greater extent than normodivergents; moreover, hyperdivergent patients exhibited a decreased mandibular divergence at the end of the treatment.

Two Phases

The variety of etiological factors contributing to the development of distal bite various form, as well as the structures that are affected by the disorders determine the deegre of complexity of the malocclusion itself, and thus the choice of therapeutic procedure by which it will be treated. An 11-year-old female patient was diagnosed with this type of malocclusion with a certain degree of presence of other irregularities. After a detailed diagnostic procedure, and determining the type of growth, we approach the therapeutic procedure in two phases. By applying the funcional therapy in the first phase, we correct the vertical growth type, and then in the second phase of therapy using a fixed technique we achieve harmonious intermaxillary relations, an adequate molar and canine Class I relationship as well, thus improving the aesthetics of the patient's face.

In Reply.— Sharon's impression that children with a specific facies might be more prone to otitis, if true, might mean that there is an association between certain facial growth pattern and aberrant Eustachian tube function. Along the same lines, there is limited evidence and much discussion about the incidence of ear problems being higher in allergic children; their Eustachian tubes are compromised by the changes induced by hypersensitivity reactions in the contiguous area. As intimated by Sharon, perhaps the sequelae of chronic rhinitis are twofold: facial growth abnormalities and Eustachian tube dysfunction.

Cellular fibrous histiocytoma, a variant of fibrous histiocytoma, is a designation used for lesions showing increased cellularity with a fascicular growth pattern and frequent extension into the subcutis. Here we describe a case of cellular fibrous histiocytoma showing repeated recurrence in a 36-year-old woman who initially presented with a 2-cm cutaneous tumor on her right elbow. Histopathologically, the first resected specimen demonstrated irregularly arranged collagen fibers mixed with scattered proliferating plump to spindle-shaped fibrohistiocytes. However, examination of the resected specimens obtained after recurrence showed that the cellularity had increased, the spindle-shaped cells showing monomorphic proliferation with a fascicular and storiform growth pattern extending into the subcutis, as well as an increase of Ki-67 positivity. Since the lesion showed repeated relapse within a short period, we performed wide-field resection of the tumor with a 3-cm margin. Currently, 48 months after surgery, there has been no local recurrence or metastasis, but continuous strict follow-up will be necessary.
