Radical Mastoid Operation without Grafting or Meatal Plastic (Bárány)

Caldwell-Luc operation without inferior meatal antrostomy: a retrospective study of 50 cases.

PURPOSE In the standard Caldwell-Luc operation, an inferior meatal antrostomy is performed to promote sinus drainage. However, inferior meatal antrostomy has been criticized for its additional operation time and wound, early loss of the opening, and risk of injury to the nasolacrimal duct. This study retrospectively reviewed the results of the Caldwell-Luc operation without inferior meatal antr...

Mastoid Suppuration without Tympanic Perforation and Suppuration

Mastoidectomy using an osteoplastic flap.

DURING the past 20 years there have been numerous changes in our approach to mastoid surgery. New procedures have been evolved, and old ones discarded or sometimes revived. In our present state of knowledge, three principles govern our approach to surgery of chronic ear and mastoid suppuration. Firstly, all disease and especially all cholesteatoma, must be eradicated at operation. As a corollar...

Imre Bárány, Lecture 4

Let X ⊂ R d be a set of n points in general position (i.e. no d + 1 points of X lie on the same hyperplane.) For a positive 0 < ε < 1, we define A finite set S ⊂ R d is called a (weak) ε-net of X if S ∩ F = ∅ for any F ∈ F ε. We note that S is called a strong ε-net if, in addition, it also satisfies S ⊂ X. Since we are only going to discuss weak ε-nets, we will simply call these ε-nets. Our goa...

Sural Nerve Interposition Grafting during Radical Prostatectomy.

In 1997, autologous sural nerve grafting to reconstruct bilaterally resected cavernosal nerves was successfully performed in patients undergoing radical retropubic prostatectomy. After 12 months, one third of these patients had erections sufficient for intercourse. Since that time, patients who have had neurovascular bundle resection and sural nerve grafting have continued to show promising res...
