Temporomandibular joint disc perforation: long-term results after operative arthroscopy.

Purpose: Disc perforation (DP) is one of the most important pathologic signs of intracapsular temporomandibular joint (TMJ) disease; however, few clinical studies have focused on the arthroscopic management of this feature. The purpose of the present study was to assess whether operative arthroscopy with abrasion of the perforation borders is effective for the treatment of this alteration of the internal derangement of the TMJ.

Patients And Methods: Thirty-six patients (39 joints) who underwent TMJ arthroscopy under general anesthesia and presented with DP (Wilkes stages IV and V) from 1994 through 2006 were included in this study.

Unsuccessful temporomandibular joint arthroscopy: is a second arthroscopy an acceptable alternative?

Purpose: Arthroscopic surgery has been shown to be an effective treatment for patients with temporomandibular disorders, relieving patients' symptoms and restoring adequate mandibular function. For those patients with poor arthroscopic outcomes, various treatment modalities are possible, such as nonsurgical therapy, open surgery, or repeat arthroscopic surgery. The purpose of this study was to evaluate our results with rearthroscopy in patients with temporomandibular joint dysfunction.

Preprosthetic and implantological surgery in patients with severe maxillary atrophy.

Aims: To evaluate the success of the osseointegration of dental implants in patients with severe maxillary atrophy after sinus lift augmentation and onlay graft surgery with autologous bone grafts.

Design: A descriptive and analytic study of 27 patients with severe maxillary atrophy and partial or total edentulism, after 4 years follow-up. All cases underwent to autologous bone graft sinus lift augmentation with or without onlay grafts in the anterior maxillae.
