[Results of fine needle aspiration biopsy, frozen section diagnosis and definite histological results in thyroid pathology. Report of 163 cases].

Introduction: In thyroid diseases, the place of fine needle aspiration biopsy still continues to be discussed: the sensibility and specificity vary greatly in the literature. Frozen section diagnosis is necessary to form a diagnostic strategy. The objective of this study was compare the results of fine needle aspiration biopsy, frozen section diagnosis, and definitive histologic results in a population of 163 patients and to draw conclusions about treatment.

Ossiculoplasty with total hydroxylapatite prostheses anatomical and functional outcomes.

Objective: To evaluate the results of partial and total ossicular reconstruction prostheses entirely made of hydroxylapatite.

Study Design: A retrospective review of cases followed-up between 1997 and 2000.

Setting: Tertiary referral center.

[Otosclerosis surgical techniques and results in 150 patients].

Objectives: To analyze outcome after otosclerosis surgery with stamedeotomy with blood clot sealing.

Patients And Methods: Otosclerosis surgery was performed in 150 adult patients between 1997 and 1999 by five surgical teams (70% of the procedures were performed by senior surgeons) and followed for 18 months. Stapedotomy was carried out under general anesthesia with an intrameatal approach in 96% of the cases.

[Predictive factors of outcome in 220 ossiculoplasties in adults].

Objective: To define factors predictive of outcome after ossiculoplasty in adults.

Material And Methods: From 1992 to 1998, 220 ossiculoplasties were performed for chronic otitis media in 200 patients (100 men and 90 women), average age 53 years, age range 17 - 82 years. Ninety-four patients (47%) had not undergone prior surgery (99 ossiculoplasties) and 106 (53%) underwent revision procedures (121 ossiculoplasties).
