Estudo da relação entre a respiração oral e o tipo facial

Abstract

Breat hing is responsible for facial and cranial morphology development. Aim: investigate in order to see if there is any relationship between oral breathing and facial type. Material and Methods: 119 male and female teenagers, with ages ranging between 15 and 18 years. The sample was separated in two groups: A-50 teenage oral breathers, 28 males and 22 females; and group B-69 teenage nasal breathers, 37 males and 32 females. The sample was collected at the Centro de Atendimento e Apoio ao Adolescente do Departamento de Pediatria da UNIFESP/ EPM. We evaluated breathing and facial measures. Results: by means of anthropometric indexes we classified facial types and associated them with the person's breathing type, Hypereuriprosopic (Total=0; oral breathers 0%; nasal breathers 0%; Euriprosopic (Total=14; oral breathers 2.52%, nasal breathers 9.24%;Mesoprosope (Total=20; oral breathers 19.32%; nasal breathers 21.01%, Leptoprosopic (Total=37; oral breathers 14.29%; nasal breathers 16.81%; Hyperleptoprosopic (Total =48; oral breathers 5.89% nasal breathers 10.92%). The mesoprosopic facial type was found in 48 teenagers (40.33%) of whom 25 (21.01%) were oral breathers and 23 (19.32%) were nasal breathers. Conclusion: it was not possible to prove the existence of an association between oral breathing and facial type.

Medidas antropométricas orofaciais em crianças de três a cinco anos de idade

“…Corroborating the present study, a recent research 14 with oronasal and nasal breathing found that the orofacial measurements were similar between the two groups. The findings of that study were similar to those obtained in different studies 7,30 , which, even when using different methodology, suggest that respiratory mode cannot be considered as a primary factor for orofacial changes. However, the respiratory mode diagnosis only through Speech-Language Pathology evaluation is considered a limitation of the current study.…”

Medidas faciais em indivíduos adultos sem queixas orofaciais: compatibilidade entre medidas antropométricas e percepção facial

“…Despite conflicts between studies in the literature that showed that there is not a direct relationship between the measurement by caliper and perceptual evaluation, it is important to note that different methods of objective assessment were used [15][16][17] , which changes the perspective of facial analysis that cannot be employed in the perceptual evaluation. Nevertheless, the relationship between the caliper measurements used in this study proved to be very accurate with the perception of face typology, as are numerical relations that are implicitly used to evaluate the perception of face typology, hypothesis confirmed according to the presented results.…”

“…Besides the relationship between height and width allows inferences about the functional changes, the relationship between the hemi-faces also allows this characterization, especially being related to masticatory changes, parafunctional habits and disorders of the temporomandibular joint 17 . This evaluation also revealed a substantial relationship between analyzes performed, observing nearly a full compatibility between tests to determine symmetry.…”

“…Clinical speech-language pathology evaluation of the respiratory mode was conducted by a speech-language therapist with expertise in the area, who was responsible for the screening and speech-language assessments of the hospital sector, according to Bianchini et al 2 . Mode of breathing was considered adequate (Nasal Breathing Group -NB group) when the patients' lips were occluded at rest and exclusive nose respiration was used with a possibility of labial sealing ≥3 minutes, measured by a digital chronometer, TIMEX manufactured (T5K491SR/TI Manaus, AM, Brasil).…”

“…In contrast, oral breathing presents multifactorial etiology, either due to obstruction of the upper airways or habits that cause air to pass through the mouth 2 . Such a respiratory mode may alter the growth of maxillary bones with a decrease in their transverse dimension 3 , reduce the tone of the orofacial muscles (especially the lower lip Rev Odontol UNESP.…”
