Nasal cocaine abuse and centrofacial destructive process: report of three cases including treatment.

We report 3 new cases of a centrofacial destructive process associated with chronic nasal abuse of cocaine. This complex first described in 1988 is a rare entity involving sinonasal tract necrosis after cocaine abuse. Of special interest in this report is a male patient with columella and lip involvement instead of the more usual rhinopalatal destruction.

[Oral, mandibular and oropharyngeal reconstruction with a pedicled trapezius flap].

Reconstruction of large defects of the oral cavity (with or without jaw defects) and the oropharynx is one of the most important challenges in reconstructive maxillofacial surgery. Many reconstruction techniques have been proposed although none has provided total satisfaction. For each patient, accurate evaluation is required to choose the optimal solution.
