Hearing impairment in ventilator-dependent infants and children.

Bronchopulmonary dysplasia is a complication of prematurity that can require months or years of ventilatory support. Among a cohort of 12 such ventilator-dependent patients, half had auditory brainstem response thresholds of 40 dB nHL or worse in the better ear. In 10 of 23 ears the threshold was 50 dB or worse. This incidence of hearing impairment is much greater than for other high-risk premature infants. Although conductive impairment was implicated in many cases, the degree of impairment is greater than that ordinarily seen with middle ear effusion.

Vocal cord paralysis in children.

Bilateral vocal cord paralysis is a common cause of stridor in infants and children. There are significant differences in this entity between children and adults with regard to etiology, diagnosis, management, and outcome. A review of 10 years' experience at Children's Hospital of Philadelphia identified 51 children seen with the diagnosis of vocal cord paralysis. These cases were evaluated with respect to etiology of paralysis, whether unilateral or bilateral, delay in diagnosis, need for tracheotomy, abnormality of voice, surgical treatment, and outcome. Guidelines for management for a child with vocal cord paralysis are presented with emphasis on flexible endoscopic evaluation and conservative management.

Laryngotracheoplasty in the management of subglottic stenosis.

Laryngotracheoplasty (LTP) has revolutionized the surgical management of subglottic stenosis in children. A 10-year review of patients at the Children's Hospital of Philadelphia yielded 27 patients who had undergone a LTP. LTP with an anterior cartilage graft was utilized in over 80% of procedures. Morbidity was minimal, and there were no deaths. In this series, 78% of patients have been successfully decannulated. LTP has reduced the time necessary for decannulation in children with chronic tracheostomies as a result of subglottic stenosis.

Bacteriology of tonsil surface and core in children.

The tonsils of 97 children undergoing tonsillectomy were studied to determine the correlation between surface culture swab and culture of tonsillar core. In many cases, pathogenic organisms were found in the tonsil core, despite the fact that surface cultures revealed only normal respiratory flora. The tonsil core cultures showed a high incidence of Hemophilus influenzae and Staphylococcus aureus, which was rarely reflected on surface culture. The study indicates that pharyngeal swab cultures do not reliably reflect the presence of pathogens in the tonsil core. The value of parameters such as history of recurrent bouts of tonsillitis and presence of erythema or cryptic debris on physical examination for predicting the differential bacteriology of the tonsil is studied. The implications for treatment of children with adenotonsillar hypertrophy are discussed.

Microbiology of the tonsils and adenoids in a pediatric population.

To investigate the microbial flora of the tonsils and adenoids, the core tissue from the tonsils and adenoids of 50 children undergoing tonsillectomy and adenoidectomy for either recurrent infection or airway obstruction was cultured aerobically and anaerobically, and the number of bacterial colonies was quantitated. The most common organisms isolated were alpha-hemolytic streptococci, nonpathogenic Neisseria species, Haemophilus species, Staphylococcus aureus, and Corynebacterium species. No anaerobes were identified. Bacterial isolates from the tonsils and adenoids were similar in number and frequency of occurrence. Potential pathogenic bacteria (Haemophilus species, S aureus, beta-hemolytic streptococci, and Streptococcus pneumoniae) were identified in 40 patients. Seventy-three percent of these patients shared a common pathogen in tonsil and adenoid tissue. Haemophilus species were recovered in 54% of patients and S aureus in 46%. No significant difference exists between the type and number of pathogens in patients undergoing adenotonsillectomy for recurrent infection or obstruction.

Pediatric neck masses: guidelines for evaluation.

Neck masses are frequent findings in the pediatric population. Unlike the adult, there are few established guidelines for evaluation of these children. The etiology of cervical masses includes many conditions. Knowledge of these conditions and their clinical presentations is essential. To elucidate the clinical characteristics which may help in establishing a correct diagnosis, the charts of 445 patients with biopsies of neck masses performed at the Children's Hospital of Philadelphia were analyzed. There were 244 (55%) congenital lesions, 118 (27%) inflammatory lesions, 23 (5%) non-inflammatory benign masses, 12 (3%) benign neoplasms, and 48 (11%) malignancies. The preoperative diagnosis was correct in 270 (61%) patients. Guidelines are established for the evaluation of the child presenting with a neck mass.

The anterior cricoid split: the Children's Hospital of Philadelphia experience.

The anterior cricoid split procedure (ACS) is an alternative to tracheotomy in selected infants with subglottic stenosis. From February 1983 to October 1987, 26 children underwent ACS at the Children's Hospital of Philadelphia. All children had subglottic stenosis. Six children had previously undergone tracheotomy. A successful outcome, allowing extubation or decannulation, correlated only with decreased pre-operative intubation time and was achieved in 73% of these patients. A failed ACS had little adverse affect on the subsequent management of these children.

A prospective study of titanium ventilation tubes.

A prospective controlled study was undertaken in which in 100 children a titanium ventilation tube was inserted in one ear, and a Paparella silicone tube was inserted in the contralateral ear as a control. The tubes were evaluated with respect to length of time of intubation, episodes of otorrhea, and early occlusion. Sixty-five patients were followed for at least one year, or until both tubes had extruded. Long-term follow-up of these patients has revealed little difference in the incidence of tube occlusion, early extrusion, or infection with otorrhea. Since the titanium tube is more than twice as expensive and has no proven advantages over a silicone tube of similar design, we have no reason to recommend its use over the less costly, standard silicon ventilation tube.

Pediatric orbital tumors.

The proper management of orbital tumors in children requires a knowledge of the lesions commonly seen in this area, in addition to the appropriate methods of investigation and treatment. A multidisciplinary approach is most beneficial in obtaining the desired results.

Cholesteatoma in the pediatric patient.

A review of patients with cholesteatoma at the Children's Hospital of Philadelphia from 1981 to 1986 yielded 161 children. Analysis of data from both outpatient and hospital charts revealed a higher incidence of males to females, and the peak incidence of cholesteatoma appeared to be in the 6-10 year age group. Otorrhea was the most common symptom; and on physical examination, the posterior-superior quadrant was most often affected. Both intact canal wall and open cavity procedures were employed depending upon the site and extent of disease. Seventy-six percent of patients underwent an intact canal wall or middle ear procedure initially, with the remainder requiring an open cavity procedure. Recurrent or residual cholesteatoma was found in 32% of 148 patients at the second procedure, and in 7% of 148 patients if a third procedure was necessary. Pre- and post-operative audiometric findings for 91 patients revealed 21% with decreased hearing post-surgically, 50% with no change in hearing and 29% with improved hearing. Post-operative complications were minimal.

The sternocleidomastoid tumor of infancy.

The sternocleidomastoid tumor of infancy is an uncommon clinical entity which has received little attention in the otolaryngological literature. The diagnosis must be considered in any infant presenting with a lateral neck mass. Although its natural history favors spontaneous regression, the mass may initially grow in size. The purpose of treatment is the prevention of torticollis and craniofacial asymmetry. The initial treatment is non-surgical, passive and active exercises. Only when this treatment fails should surgery be performed. The disappearance of the lesion is not always a predictable sign. A small number of children will develop delayed torticollis or craniofacial asymmetry. It is important that parents be informed of this possibility and of the necessity for long term follow-up.

Malignant fibrous histiocytoma of soft tissue in childhood.

Seven children aged 6 months to 11 years with malignant fibrous histiocytoma, a type of sarcoma of soft tissues, have been treated at the Children's Hospital of Philadelphia from January 1975 through July 1983. The primary tumor arose in the head and neck region in three patients, the chest wall in two patients and the pelvis or buttock in one patient each. Operative management consisted of complete tumor removal in the two patients with chest wall tumors, and biopsy only in the remaining five children. Afterward, all seven patients were treated with a multiple-agent chemotherapy program consisting of vincristine, dactinomycin, and cyclophosphamide for two years, with or without Adriamycin (doxorubicin). The five patients with residual tumor also received radiation therapy (RT) in doses of 1500 to 5500 rad. The two children with localized, completely excised sarcoma are continuously free of tumor at 1.4 and 9 years after initiation of treatment. Of the five with residual sarcoma, three had a complete response to radiation and chemotherapy, and two of them are free of recurrence at 4 and 5 years, respectively. In the three remaining children, the tumor spread regionally into the central nervous system or distantly into the lungs, subcutaneous tissues, and liver. Childhood malignant fibrous histiocytoma of soft tissue appears to be similar to childhood rhabdomyosarcoma in its modes of spread and response to management. Operative removal is the key to successful therapy. The roles of multiple-agent chemotherapy and RT remain to be defined. Adriamycin appears to be the most promising single agent. In the absence of concrete data, it seems prudent to follow the same guidelines for irradiation as those used for other soft tissue sarcomas of childhood.

The effect of antibiotic therapy on recovery after tonsillectomy in children. A controlled study.

Tonsillectomy continues to be a commonly performed operation in the pediatric age group. The postoperative period is often protracted and characterized by throat and ear pain, intermittent fever, foul odor from the oral cavity, and poor oral intake. Consequently, antibiotics are frequently prescribed in an effort to minimize these symptoms and/or avoid complications such as dehydration or secondary infection of the operative site. However, to our knowledge, no study to date has been performed to demonstrate the efficacy of antibiotic therapy in this setting. At the Children's Hospital of Philadelphia, a prospective, randomized, double-blind study was undertaken in which ampicillin (or placebo) was administered intravenously at the time of surgery and for 12 to 24 hours postoperatively. The children then continued to receive oral amoxicillin therapy (or placebo) for an additional seven days. The patients were then evaluated for the incidence and severity of postoperative symptoms and complications. Intraoperative cultures of the oropharynx and tonsillar tissue, as well as cultures of the tonsillar fossa, were obtained following completion of one week of therapy. Our results indicate that ampicillin sodium/amoxicillin trihydrate therapy is well tolerated and safe in the nonallergic child and is effective in minimizing fever and other troublesome postoperative symptoms, such as pain, lassitude, mouth odor, and poor oral intake after tonsillectomy.

Post-tonsillectomy hemorrhage: incidence, prevention and management.

Tonsillectomy (with or without adenoidectomy) continues to be a commonly performed operation in the United States. Over the years, the incidence of post-tonsillectomy hemorrhage (reported between 0% and 20%) has decreased, but continues to pose serious problems. We reviewed 1,445 tonsillectomies performed over a 2-year period to study the incidence of post-tonsillectomy hemorrhage. Thirty-eight of 1,445 children (2.62%) had postoperative bleeding. The incidence of primary hemorrhage (within 24 hours) was 0.14%. Delayed hemorrhage requiring operative intervention or observation in the hospital was 1.03% and 0.76%, respectively. Ten patients (0.69%) had delayed hemorrhage of a minor nature that had stopped by the time they reached the hospital; these children were treated with observation alone and did not require hospitalization or operative intervention. The proposed reasons for this low rate of post-tonsillectomy hemorrhage include complete preoperative coagulation screening, meticulous attention to surgical technique, use of suction-cautery to obtain hemostasis and, possibly, use of postoperative antibiotics. Management of hemorrhage is discussed with respect to observation, surgical intervention, and blood transfusion.

A controlled study of a 'new' ventilating tube. The gold standard?

A prospective controlled study of a gold ventilation tube was undertaken in which a gold tube was inserted in one ear of 88 children and a Paparella silicone tube was inserted in the contralateral ear as a control. The tubes were evaluated with respect to length of time of intubation, episodes of otorrhea and early occlusion. Sixty-three patients were available for a follow-up of at least 6 months. The gold tube remained in place for a shorter period of time when compared to the control tube. Episodes of otorrhea were infrequent and there was not any significant difference between the two types of tubes. The gold tube became occluded more frequently than the control tube. Since the gold tube is approximately 3 times more expensive and has no proven advantages over our conventional silicone tube, we have no reason to recommend its use in preference to any other available tube.
