Objective. To study the correlation between lateral cephalogram, flexible laryngoscopy, and sleep study in patients diagnosed with obstructive sleep apnea (OSA). Background. Screening tools should be devised for predicting OSA which could be performed on an outpatient basis. With this aim we studied the skeletal and soft tissue characteristics of proven OSA patients. Methods. A prospective stud...

UNLABELLED Several studies have investigated the effects of septoplasty on facial growth in children, with conflicting results. However, just handful of those employed objective measures or evaluated patients after facial growth completion. OBJECTIVE This study assesses the effects of the Metzenbaum septoplasty, which preserves the perichondrium and growth-related areas on nasal and facial gr...

Since from the introduction of cephalometric analysis in diagnosis and orthodontic treatment planninjg, it plays a major role .So many efforts have been made by various studies to standardize the values for different reces , to minimize the distortion and magnification , to create universally accepted analysis, even after this still so many limitations are there in diagnosis of orthodontic trea...

We focus on the problem of shape variability modeling in statistical pattern recognition. We present a nonlinear statistical model invariant to affine transformations. This model is learned on an ordinate set of points. The concept of relations between model components is also taken in account. This model is used to find curves and points partially occulted in the image. We present its applicat...

BACKGROUND Complete tooth loss (edentulism) produces anatomical changes that may impair upper airway size and function. The aim of this study was to evaluate whether edentulism favours the occurrence of obstructive sleep apnoea (OSA). METHODS Polysomnography was performed in 48 edentulous subjects on two consecutive nights, one slept with and the other without dentures. Upper airway size was ...

OBJECTIVES/HYPOTHESIS To analyze the prevalence of adenoid regrowth at 1 year after coblation adenoidectomy using cephalometric radiography. STUDY DESIGN Retrospective analysis. METHODS One hundred eighty-eight children who underwent adenoidectomy from June 2006 through September 2010 were included. Demographic data, preoperative size of palatine tonsils, presence of allergic rhinitis, conc...

OBJECTIVE To report our experience with cephalometry in evaluating velopharyngeal dysfunction (VPD) in velocardiofacial syndrome (VCFS) and its utility in assessing the role of cervical spine abnormalities in VPD, prior to surgical correction of VPD. DESIGN Clinical charts and cephalometric radiographs done prior to surgery for VPD were retrospectively analyzed to ascertain velopharyngeal mea...

OBJECTIVE To compare a new ultrasound measurement method with calliper cephalometry in infants with deformational plagiocephaly (DP) and to assess the differences of two methods according to the severity of DP. METHODS Fifty-two infants with DP were divided into two groups according to the degree of cranial vault asymmetry (CVA); group 1 included 42 infants with CVA over 10 mm, and group 2 in...

Oral submucous fibrosis (OSMF) is a chronic insidious disease affecting mucosa and submucosa of oral cavity and soft palate. The present study aimed to evaluate the morphology of soft palate in normal individuals and OSMF patients using lateral cephalometry and to compare and correlate these variants of soft palate with different stages of OSMF. 100 subjects were included in the study, who were...

In a curved tube, the amount of airflow appears to be influenced by the amount of curvature. The purpose of this study was to investigate changes in obstructive sleep apnoea (OSA) severity and awake velopharyngeal curvature in response to an anteriorly titrated mandibular position in 20 male OSA patients. Baseline supine cephalometry was obtained before the initial insertion of a titratable ora...
