Presents an imaging case study of osteoid osteoma of the frontal bone. Patient profile; Definition of osteoid osteoma; Coronal computed tomography scan of sinuses.

Objectives: Our intent was lo review the clinical signs, computed tomography (CT) scans, treatment, and outcome of parapharyngeal space infections (PPIs), and to define 2 types of infections of the parapharyngeal space (PPS) according to the location of the infectious process. Methods: We performed a retrospective analysis of patients hospitalized in a tertiary university hospital with a diagnosis of PPI, abscess, or deep neck abscess between 1988 and 2004. Files and CT scans were reviewed after classification into 2 groups: 1) infection located in the posterior part of the PPS (PostPPI): and 2) infection located in the anterior part of the PPS(AntPPI). Results: Twenty-two patients had a PostPPI: their ages ranged from 10 months to 24 years. Five patients underwent surgical drainage, and 17 others were treated solely with intravenous antibiotic therapy. No pus was found during surgery in 2 patients. The average time of hospitalization was 10 days. Only 1 complication (aspiration pneumonia) was observed. Seven patients had an AntPPI; their ages ranged from 1.5 years to 65 years. All patients underwent surgical drainage, and pus was detected in all cases. The average time of hospitalization was 35 days. Complications (septic shock, respiratory arrest, mediastinitis. pleural empyema. pericarditis) were observed in 4 patients. Conclusions: The term ‘parapharyngeal abscess’ was assigned long before the CT scan era, and was based on physical examination and plain film radiology. In essence, the entity PPS ‘abscess’ or ‘infection’ is composed of 2 different disorders. Infection located in the posterior part of the PPS with no invasion into the parapharyngeal fat and with no extension into other cervical spaces except the adjacent retropharyngeal space may be termed posterior parapharyngeal infection or parapharyngeal lymphadenitis. This is a relatively benign condition, and nonsurgical treatment should be considered. Infection involving the parapharyngeal fat may be termed parapharyngeal abscess or deep neck abscess. Diffusion into the mediastinum and other severe complications are frequent. Urgent surgical drainage is therefore mandatory. [ABSTRACT FROM AUTHOR]

Objective: The average age of children undergoing tracheotomy has declined over the years and the indications for tracheotomy have changed from acute airway obstruction due to infection, to treatment of chronically ill children. Tracheotomy-related complication rates are more numerous in younger children and in certain cases have proved to be fatal. A variety of operative techniques have been advocated for reducing the rate of tracheotomy-related morbidity and mortality. This manuscript reports on our experience with a new technique—starplasty tracheotomy (SPT)—and assesses the value of this procedure in preventing tracheotomy-related complications in infants (under 6 months old), in whom complications are more frequent and more dangerous. Methods: Children less than 6 months old who underwent tracheotomy in the Department of Otolaryngology/Head and Neck Surgery, Hadassah University Hospital, Jerusalem, between the years 1999 and 2003 were studied. They were divided into two groups according to the surgical technique preferred and performed by the senior surgeon on call. Children in group 1 underwent tracheotomy by means of a regular technique and children in group 2 underwent SPT. All events related to the tracheotomy were recorded and a comparison was made between the two groups. Results: Eleven of a total of 26 pediatric tracheotomy patients were less than 6 months old. Five underwent regular tracheotomy (RT) and six underwent SPT. Three complications were encountered in the RT group and none in the SPT group. Accidental decannulation and failure to re-insert the cannula resulted in severe hypoxemic brain damage in one patient with RT. No tracheotomy-related deaths occurred. Conclusion: Our experience supports the existing data regarding the superiority of SPT over RT in preventing dangerous tracheotomy-related complications in infants. We, therefore, recommend performing SPT in all infants undergoing tracheotomy, even at the price of having to perform surgical closure of TCF after decannulation in some cases.
