[Complications of endoscopic sinus surgery in a residency training program].

Introduction: Endoscopic sinus surgery presents a series of complications that can vary depending on the technique used and the surgeon's experience. This technique needs a learning curve, which must be developed during the residence training program.

Methods: Descriptive and retrospective study, reviewing the medical records of endoscopic sinus surgery for nasal polyps of 192 patients who had undergone operations performed by residents at our department between January 2002 and January 2008.

Rhino-orbito-cerebral mucormycosis, a retrospective study of 7 cases.

Mucormycosis is an opportunistic fungal infection caused by fungi of the Mucorales order. It has a low incidence and is a potentially lethal infection which generally affects patients who are immunocompromised due to systemic disease. We report 7 cases of rhinocerebral mucormycosis in a retrospective study of 8 years (2000-2008) in haematological patients.
