RESUMO
Describing a newly designed frame holder applied to the head before pin fixation. The already available ear plugs facilitate the straight alignment of the frame by fixing it to the external auditory meatus, but they are quite painful for most of the patients and not prevent the anterior posterior rotation. The Leksell frame [Elekta, Sweden] is provided with a clamp that fits only with Mayfield head frame[SM, USA]. We performed certain modifications to make the frame fit to the Sugita head clamp [Mizuho, Japan]; the only sort of head frame we have in our hospital. The new modifications were used to fifteen patients in whom the application of the frame was indicated. A new designed net made of sewed ribbons applied to the head before pin fixation. It prevents slipping of the frame especially with the aid of the top plastic cup for its suction ability over a well shaved head. No pain recorded with its use. The other modification was to make few changes with the sugita head clamp middle piece to make it adaptable with that of the Leksell which was originally designed for the Mayfield head clamp. The newly designed net caused no pain to all the patients .Slipping was minimal. The time of the application of the frame shortened. With the use of the new adapter with the Leksell frame, we were able to perform surgical interventions even as long as 8 hours as in deep brain stimulation operations with no movement noticed between the frame and the operating table. These two technical modifications were useful to help in application of the frame over the patients head with minimal slipping movement and no pain. It permitted us to use the Leksell frame with the sugita head frame which is the only sort of head frame we have in our hospital
