Vascular clinical anatomy of the submandibular gland.

Objective: The aim of this study is to describe in depth the precise anatomy of the vascular supply of the submandibular gland, trying to determine the existence of patterns of glandular vascularization. Knowledge of these patterns could facilitate surgical management of the gland and the submandibular gland flap.

Material And Methods: Neck dissections of formaldehyde preserved human cadavers were performed.

Efficacy of cartilage palisade tympanoplasty: randomized controlled trial.

Objectives: To calculate the efficacy (evaluating both morphologic and functional results) of cartilage palisade tympanoplasty (CPT) in comparison with tympanoplasty involving a temporalis muscle fascia (FT) graft.

Study Design: Randomized controlled trial.

Setting: General Hospital.
