RESUMO

A morphological peculiarity was observed in the form of an aberrant lateral bony attachment of the orbital part of the Orbicularis oculi muscle on the zygomatic bone, during routine dissection of a cadaver of an adult male of Indian origin. Fibers of this part of the muscle are not known to show any lateral attachment on bone. This paper discusses the presentation, probable embryological cause and clinical implications of this unusual finding.

RESUMO

For radical surgery of the past, the precise definition of the clefts of the paranasal sinuses was of limited significance. In the recent years, the transsphenoidal approach to the pituitary gland has come into practice and the study of the surgical anatomy and relationships of the sphenoid sinus has gained increased significance. To better define this anatomy, 20 sphenoid sinuses in cadavers were dissected to reveal important anatomical relationships, dimensions, volume and pneumatization of the sphenoid sinus. The results of the study are discussed with particular reference to the important surgical anatomical features of the sphenoid sinus. The results also point towards the possibility of racial variations in terms of relationships of the sphenoid sinus to internal carotid artery and optic nerve in the Indian population.


En las cirugías radicales del pasado, la definición precisa de las hendiduras de los senos paranasales fueron de importancia limitada. En los últimos años, el abordaje transesfenoidal de la hipófisis y las relaciones del seno esfenoidal han tenido en la práctica y en el estudio de la anatomía quirúrgica, un significativo incremento. Para definir mejor esta anatomía, 20 senos esfenoidales fueron disecados en cadáveres para revelar importantes relaciones anatómicas, dimensiones, volumen y neumatización del seno esfenoidal. Los resultados de este estudio son discutidos con referencia particular para la anatomía quirúrgica del seno esfenoidal. Los resultados también apuntan hacia la posibilidad de variaciones raciales, en términos de relaciones del seno esfenoidal con la arteria carótida interna y el nervio óptico, en la población de la India.
