Herpetic croup: two case reports and a review of the literature.

Croup is an acute infectious illness usually occurring in children; it is characterized by brassy cough and stridor. The main pathogens include mainly parainfluenza and influenza viruses. Recently there have been reports of prolonged croup caused by the herpes simplex viruses. We report two cases of prolonged croup due to herpes simplex types 1 and 2. We also review and summarize the reported pediatric cases of herpetic croup.

Lateral division of the rabbit cricoid cartilage: its effect on cartilage growth.

Laryngotracheoplasty often includes bilateral lateral division of the cricoid cartilage, despite the theoretical risk that cartilage growth centers might be located in the lateral cricoid. To investigate the effect of lateral cricoid cartilage division on subsequent cartilage growth, 60 five-week-old New Zealand white rabbits were divided into four groups of 15 animals each. Group I was comprised of unoperated controls. The remaining animals underwent anterior (group II), anterior and posterior (group III), and anterior, posterior, and bilateral lateral (group IV) division of the cricoid cartilage. Animals were killed 20 weeks after surgery, and the cross-sectional area of each animal's cricoid cartilage and of each animal's airway was determined. There was no statistically significant difference in mean cartilage cross-sectional area between any of the four groups; the group IV mean was larger than that of any other group, though the difference was not significant. There was no significant difference in airway cross-sectional area between any of the groups operated on. From these results, lateral cricoid division in the growing animal does not appear to interfere with subsequent normal growth of the larynx.

Asymptomatic osteomas of the middle ear.

Osteomas of the middle ear are extremely rare lesions. Of the nine cases reported, eight presented with conductive hearing loss. We recently treated two patients whose osteomas, of the promontory and of the posteroinferior tympanic wall, were asymptomatic. We suggest that middle ear osteomas need not be removed when they do not impinge on the sound conduction system.

Operative complications of tracheoesophageal puncture.

Tracheoesophageal puncture is not a complex procedure; nevertheless, significant complications are possible. In the last four years we have performed this procedure in 47 patients. Seven of them (15%) sustained significant complications related to the procedure. These included three cases of mediastinitis and sepsis, although surgical drainage was not required. Three other patients developed cellulitis of the trachea and root of the neck, centered around the tract through the party wall; one patient suffered a fracture of the cervical spine. Eight lesser complications also occurred. Tracheoesophageal puncture's simplicity and effectiveness surpass those of any other surgical procedure for voice restoration. However, our experience demonstrates that, as with any operation, the technique may be associated with significant operative complications.

Anterior cricoid split. Update 1991.

The management of neonatal subglottic stenosis by the anterior cricoid split procedure (ACS) has evolved rapidly since this operation was first described by Cotton and Seid in 1980. Recent reports have specified criteria for the evaluation of patients for ACS, and adherence to these guidelines has increased the extubation rate and decreased the mortality rate in these series. Ninety-one patients have undergone anterior cricoid split at Children's Hospital Medical Center (Cincinnati, OH) since 1977. These cases were reviewed, emphasizing the 24 infants treated since January 1, 1988, and not previously reported. In comparison to our most recent report of 70% extubation and 10.4% mortality, 67% of the latest group were extubated, while mortality was reduced to 4.1%. These results were achieved despite some relaxation of strict patient-selection guidelines when this was appropriate in individual patients, emphasizing the need for careful clinical evaluation and close consultation between otolaryngologist and pediatrician in the selection of patients for ACS.
