BACKGROUND The spread of infection from the ethmoid sinuses to the orbit occurs directly through a congenital dehiscence of the lamina papyracea or via haematogenous spread through ophthalmic venous system. Hence orbital complications of paediatric rhinosinusitis are usually unilateral at presentation. METHODS We describe three children with bilateral orbital cellulitis that occurred as a com...

OBJECTIVES To establish MRI criteria to diagnose early osteomyelitis in sickle cell disease patients with acute bone crisis and to differentiate it from normally occurring ischaemic changes in these patients. METHODS MRI study with and without Gadolinium contrast was carried out in 59 sickle cell disease patients who presented with acute bone crisis from August 2007 to July 2008, and had clin...

We report the case of an 11-year-old girl with sickle cell disease who presented to the emergency room after being hit by a mud pie in the left frontal region. Examination evidenced left eye proptosis, eyelid swelling, reduced visual acuity and afferent pupillary defect, without any inflammatory signs such as fever, hyperemia or tenderness. Computed tomography of the orbits showed a large super...

Purpose: To identify the right plane in augmented rhinoplasty to help facilitate the facial plastic surgeons in creating more natural look in oriental noses. Materials and methods: One hundred and ten adult Thai cadavers comprising 61 males and 49 females from Department of Anatomy, Faculty of Science, Mahidol University were included in this study. Augmentation rhinoplasty with the closed tech...

This study examined whether the number and type of sutures used in oral surgery influence two ad hoc variables (incision plane and displaced area), which are two variables related to whether the suture needle is suitable for the task. Seventy-five TB-15 needles were studied, which were used to suture between zero and three mucosa and/subperiosteal sutures, producing 15 groups with 5 needles in ...

INTRODUCTION Subperiosteal preparation using a periosteal elevator leads to disturbances of local periosteal microcirculation. Soft-tissue damage can usually be considerably reduced using piezoelectric technology. For this reason, we investigated the effects of a novel piezoelectric device on local periosteal microcirculation and compared this approach with the conventional preparation of the p...

PURPOSE To describe the CT findings of orbital cellulitis due to sinusitis. METHODS The records and CT scans of 45 consecutive patients with orbital cellulitis due to sinusitis treated at the Hospital of the Medical School of Ribeirão Preto were analyzed by a radiologist and two orbital surgeons. RESULTS Three major types of CT changes were observed: diffuse fat infiltration, subperiosteal ...
