What is a total Ethmoidectomy?

A complete ethmoidectomy is the removal of the anterior and posterior ethmoid air cells. ▪ A complete ethmoidectomy follows a maxillary antrostomy and is one component of complete functional endoscopic sinus surgery.

Can well Luc operation?

The Caldwell-Luc operation uses an external approach for surgical treatment of the severely diseased maxillary sinus. It is an alternative to middle meatal antrostomy done via endonasal endoscopic surgery and was the primary approach used for accessing the maxillary sinus before the advent of endoscopic sinus surgery.

What does osteoblastic activity refer to?

Osteoclastic activity refers to the body's process of breaking down bone in order to build it up again. ...

What is external ethmoidectomy?

An external ethmoidectomy begins with a tarsorrhaphy on the ipsilateral eye in order to prevent corneal injury. The incision is made halfway between the medial canthus and the midline of the nose down to bone. Lateral elevation of the periosteum exposes the anterior lacrimal ridge and the lacrimal fossa.

What is the survival rate of a craniotomy?

How much does a decompressive craniectomy cost?

The general mortality index was 68.8%. The total cost was R$ 2,116,960.22 (US$ 661,550.06) and the mean patient cost was R$ 66,155.00 (US$ 20,673.44). Conclusions: Decompressive craniectomy for TBI is an expensive procedure that is also associated with high morbidity and mortality.

What is a Lothrop procedure?

The modified Lothrop procedure or frontal sinus drill-out is a completely intranasal technique that creates a common frontonasal communication to allow drainage and ventilation of the chronically infected frontal sinus. It is an effective alternative to the classic frontal sinus obliteration.

How do you open a sphenoid sinus?

Sphenoid sinus can be opened with several techniques. The ostia can be directly approached.
