Anatomical control of the lower nasal width in Le Fort I osteotomy / Control anatómico del ancho nasal inferior en osteotomía Le Fort I

SUMMARY: The aim of this research is to show a simple technique to obtain control in the alar base width in Le Fort I osteotomy. The technique was used in eighteen patients submitted to maxillary impaction and/or advancements (≥ 3 mm). Inter-alar width, alar base width and right/left nostril were studied before surgery and 6 months of follow-up. Data were reported as means and standard deviations; statistical analysis was realized by t test considering a p-value <0.05. Left nostril was modified 0.33 ± 1.03 mm, right nostril was modified 0.39 ± 0.98 mm after 6 months and inter-alar width show a decrease of 0.17 ± 1.15 mm. No statistical differences were observed between the preoperative and the postoperative measurements. Our results show this technique as effective in to obtain a stable position in nasal width.

RESUMEN: el objetivo de esta investigación es presentar una técnica simple para obtener el control en el ancho de la base alar en la ejecución de una osteotomía de Le Fort I. La técnica fue usada en 18 sujetos sometidos a cirugía maxilar de ascenso y/o avance maxilar mayor (≥ 3 mm). El ancho inter-alar, el ancho de la base alar y el orificio nasal derecho e izquierdo fueron estudiados antes de la cirugía y seis meses después de la misma. Los datos fueron presentados en promedios y desviación estándar; el análisis estadístico fue realizado utilizando el t test considerando un valor de p <0,05. El orificio izquierdo fue modificado en 0,33 ± 1,03 mm, el orificio izquierdo fue modificado en 0,39 ± 0,98 mm des- pués de 6 meses y el ancho inter alar mostro una reducción de 0,17 ± 1,15 mm. No se observaron diferencias estadísticas entre las mediciones obtenidas previo a la cirugía y después de la cirugía. Nuestros resultados muestran que la técnica es efectiva para obtener una posición estable del ancho nasal.

An Anthropometric Study Of Nasal Index With Its Clinical Correlation

Background: Nose is an important anatomical and physiological part of face. Its anatomy considerably affectsits function of inhalation and temperature regulation of inspired air. The anatomy is affected by genetic, racialas well as geographical factors. The aim of the study was to measure nasal height and width in the populationbeing studied so as to calculate nasal index and classify noses on the basis of calculated index.Materials and method: The study was conducted on 159 healthy volunteers aged 18-25 years in Medical CollegeBaroda, Gujarat. Nasal height and Nasal width were measured by digital vernier caliper and the nasal index wascalculated. The type of nose was determined on the basis of the nasal index.Results: In the present study the mean nasal index is found to be 73.28+10. Mean nasal index is observed as106.46+6.24 in males & 71.94+8.02 in females. The t test value calculated is 26.725 at CI 95% with P<0.0001showing highly significant difference in nasal indices of male and female. Mesorrhine is the commonest nasaltype found.Conclusion: The study will be highly useful to plastic surgeons, craniofacial surgeons, otolaryngologists,anatomists, forensic experts, orthodontists and medical illustrators alike.

Estimation of Stature from Some Selected Cephalofacial Parameters among Teenage Indigenes of Ogoja Local Government Area Cross River State.

Estimation of stature from body segment parameters finds usefulness in forensic sciences and other medical applications. However, these parameters are highly, sex, race and age dependent. The present study measured some cephalofacial parameters with a view to providing cephalofacial anthropometric parameter that could be used in estimation of stature among teenage indigenes of Ogoja Local Government Area of Cross River State. A total of 300 teenagers (13-19 years), comprising 150 males and 150 females were used. Maximum stature, head circumference, nasal height and nasal width were obtained by direct measurement. The findings of the study showed that males mean values are significantly higher (p<0.05) than females for all parameters: Stature (males, 157.30±6.81; females, 155.70±5.71), head circumference (males, 55.38±1.55; females, 54.62±1.52), nasal height (males, 4.54±0.43; females, 4.39±0.44) and nasal width (males, 4.95±0.50; females, 4.74±0.58). Results of this study reveals that male head circumference significantly (p<0.05) correlate with stature. Hence only male head circumference (HC) could be employed in the estimation of stature using the linear regression equation (11.48 × HC + (-478.70)). The analysis of the measured parameters shows that nasal height and width are not reliable tools for stature prediction amongst Ogoja teenage population.
