OBJECTIVES/HYPOTHESIS To determine the effect of mouth breathing during childhood on craniofacial and dentofacial development compared to nasal breathing in malocclusion patients treated in the orthodontic clinic. STUDY DESIGN Retrospective study in a tertiary medical center. METHODS Clinical variables and cephalometric parameters of 116 pediatric patients who had undergone orthodontic trea...

It has been maintained that because of large adenoids, nasal breathing is obstructed leading to mouth breathing and an 'adenoid face', characterized by an incompetent lip seal, a narrow upper dental arch, increased anterior face height, a steep mandibular plane angle, and a retrognathic mandible. This development has been explained as occurring by changes in head and tongue position and muscula...

The didgeridoo is a wind instrument composed of a single large tube often used as drone instrument for backing up the mids and lows of an ensemble. A didgeridoo is played by buzzing the lips and blowing air into the didgeridoo. To play a didgeridoo continously one can employ circular breathing but the volume of air required poses a real challenge to novice players. In this paper we replace the ...

The present study aimed at analyzing and comparing longitudinally the EMG (electromyographic activity) of the superior orbicularis oris muscle according to the breathing mode. The sample, 38 adolescents with Angle Class II Division 1 malocclusion with predominantly nose (PNB) or mouth (PMB) breathing, was evaluated at two different periods, with a two-year interval between them. For that purpos...

INTRODUCTION Hypertrophy of the adenoids and palatine tonsils is the second most frequent cause of upper respiratory obstruction and, consequently, mouth breathing in children. Prolonged mouth breathing leads to muscular and postural alterations which, in turn, cause dentoskeletal changes. OBJECTIVE The aim of this study was to determine muscular, functional and dentoskeletal alterations in c...

Background: Chronic obstructive pulmonary disease, which is usually caused by harmful particles or gases, associated with persistent respiratory symptoms. Aim: To determine effects of controlled breathing techniques for muscle strengthening and functional capacity. Study Design: Randomized control trial. Methodology: was conducted at Services Hospital Lahore duration 6months. Patients (n=48) we...

BACKGROUND Nasal deformity associated with cleft lip and palate is a highly challenging reconstructive problem in rhinoplasty. In the literature, several operative solutions and evaluation methods have been described, however these do not offer a standard procedure for the surgeon. Our aim was to standardize our surgical technique-as much as the uniqueness of each case allowed it-based on the m...

background vermilion irregularities are common secondary deformities after cleft lip repair, regressed or resected hemangiomas, trauma and tumor surgeries. vermilion deficiency attracts considerable attention and detracts from an otherwise excellent lip repair. minor and moderate vermilion defects can be corrected with upper lip advancement, rotation flaps, tongue flaps or grafts. major defects...

in this survey, asbestos fiber levels within the breathing zone of employers and in the environment of an asbestos-cement factory were monitored on membrane filter and counted by phase contrast optical microscope considering length/diameter>3:i (asbestos international associational method). the plant was fairly old and utilized both white (chrysotile) and blue (chrocidolite) asbestos. in each w...
