Tympanostomy tubes in children with hemophilia A.

With proper teamwork between the hemotologist and otolaryngologist, children with hemophilia A and otitis media can obtain the benefits of tympanostomy tubes; 90% phenol applied topically to the tympanic membrane is a useful hemostatic agent. The technique may allow the hemophiliac child to undergo myringotomy and insertion of tympanostomy tubes without the use of blood products. There is evidence that the use of such blood products derived from pooled human plasma may be associated with the development of acquired immune deficiency syndrome (AIDS).

Nonbacterial inflammation as a means of enhancing skin flap survival.

Painting the skin of the dorsum of a rat with croton oil improved the survival length of caudally based skin flaps. No vasodilation was demonstrated in the deeper layers of skin treated with croton oil. The mechanism by which the application of croton oil leads to improvement of the skin flap survival is thought to be the nonbacterial inflammation produced by the croton oil (a chemical burn). This inflammatory effect probably acts upon the microcirculation via arachidonic acid metabolite mediators.

Otosclerosis and Meniere's syndrome: diagnosis and treatment.

Occasionally a patient with otosclerosis and a conductive hearing loss will develop typical findings of Meniere's syndrome in the involved ear, years later. A review of clinical and pathological studies in the literature and in our laboratory and clinic indicates a likely cause-and-effect relationship for these cases. The pathology and pathogenesis of the syndrome of otosclerosis and Meniere's syndrome is discussed. A stapedectomy/sacculotomy was used to treat 17 patients, 13 of whom acquired a satisfactory result in terms of improvement of hearing and control of vertigo. This technique and findings are described and discussed.

Otosclerosis and endolymphatic hydrops.

It has been postulated that otosclerosis may produce vertigo by several mechanisms. One mechanism is by causing endolymphatic hydrops. We present six temporal bones in which otosclerosis and endolymphatic hydrops coexist. We consider that there is a spectrum-like interrelationship between these two entities. At one end of the spectrum the relationship is coincidental, while at the other end of the spectrum we consider the massive amount of active otosclerosis to be a causative factor in the development of the endolymphatic hydrops.

Bacterial tracheitis.

During a two-year period, 17 children were brought to the St Paul Children's Hospital with the clinical features of croup, unresponsive to conventional therapy; 12 of these were seen during a two-month outbreak of parainfluenza virus type 1 that occurred in the community. Bronchoscopy showed copious purulent tracheal secretions. Cultures of transbronchoscopic aspirates were positive for bacterial organisms, the most common being Staphylococcus aureus (six of 17) and alpha-hemolytic Streptococcus (seven of 17). Four of these children, all treated conservatively with observation and/or endotracheal intubation, suffered a cardiorespiratory arrest, and two of them died. In contrast, one of 13 children who underwent tracheostomy died. Bacterial tracheitis clinically resembles viral croup, but carries a significant morbidity and mortality. Bronchoscopy documenting the presence of copious endotracheal pus and prompt tracheostomy may reduce the complications of this disease.

Complications of pectoralis myocutaneous flaps.

The myocutaneous pectoralis major flap has recently caught the attention of head and neck surgeons. Over the last 12 months, our service has used this flap in 14 patients. Reconstruction in the oral cavity and larynx as well as closure of large areas of skin necrosis of the neck have been the indications. Our complications occurred in 4 of the 14 patients and included neck abscess and fistula, flap necrosis, and chest wall hematoma or abscess. The flap is an eminently useful and successful flap when designed and performed as indicated in the body of the paper.

The relationship of the facial nerve and first branchial cleft anomalies--embryologic considerations.

A Type II first cleft anomaly may lie superficial to, deep to, or between the branches of the facial nerve. The embryologic basis of this finding depends on the variable relationship between the migrating facial musculature, as it passes forward from the second branchial arch to the face, and the epithelial elements which persist in the region of fusion between the inferior portions of the mandibular and hyoid arches.

Bacterial tracheitis.

Bacterial tracheitis is a recently described clinical entity characterized by high fever, stridor, and airway obstruction. Laryngoscopy shows membraneous inflammation with notable subglottic edema and copious mucopus in the trachea. Staphylococcus aureus is the most common bacterium to be cultured. Subglottic narrowing can be seen on lateral soft-tissue roentgenograms of the neck. Bacterial tracheitis should be treated by establishing a controlled airway by endotracheal intubation or tracheotomy, rather than by usual modalities used for the treatment of croup. Bacterial tracheitis seems to be similar to croup but is more likely to be fatal. Two of the five patients described herein died.

Inflammatory pseudotumors in the buccal tissues of children.

Inflammatory pseudotumor is a nonneoplastic lesion of unknown origin. Most cases occur in the respiratory tract or orbit. This study reports three cases, all involving children, of rapidly enlarging masses in the soft tissues of the oral cavity. They were initially suspected to be malignant but proved to be inflammatory pseudotumors. The histologic appearance was that of a fibroproliferative process containing chronic inflammatory cells. The pleomorphism and mitotic activity of the fibroblasts were worrisome features. Regression without sequelae occurred in all three patients.

Christmas bow pins: a potential inhaled foreign body made safer by industrial modifications.

The 3M Company (Minnesota Mining and Manufacturing Company) has produced about three billion plastic Christmas bow pins over 20 years. When it was reported that inhalation of these pins had resulted in two deaths, the company sought otolaryngologic consultation to suggest design modifications which would decrease the risk of aspiration asphyxia. The circular base of the bow pin was modified into the form of a cross so that it would not completely obstruct the airway. Barium was added to render the bow pin radiopaque. When the unmodified bow pin was inserted into the larynx of ten cats, six died. The modified pin caused no deaths in nine cats. We regard this as an example of responsible cooperation between industry and medicine.

Intracranial abscesses with behavioral changes.

Intracranial abscesses represent one of the most serious complications of ear and paranasal sinus infections. The infection may spread by bone erosion, preformed pathways, or septic thrombosis via the Haversian canals. This may result in subdural abscesses, meningitis, or intracerebral abscesses. These intracranial complications are associated with a high morbidity. The purpose of this communication is to emphasize that behavioral changes after ear or paranasal sinus infections may be a manifestation of an intracranial abscess.

Pedunculated pharyngeal lesions.

Dentists enjoy a unique position in the health care field because they examine and treat more intraoral disease than any other specialty. It is, therefore, the responsibility of the dentist to examine the entire oral cavity and not just the teeth. Thorough intraoral examination may reveal undiagnosed pathological lesions which arise outside the oral cavity but are pedunculated and present in the mouth or oropharynx. The article presents three cases of such lesions which are potentially life threatening but may be cured if detected and treated early.
