Nasal hamartoma: case report and review of the literature.

Nasal masses in the pediatric population present with nasal obstruction, epistaxis and chronic rhinorrhea. We report on a 6-year-old boy with long-standing nasal obstruction. A large left nasal mass was evident on physical examination and CT scan. Techniques of functional endoscopic sinus surgery were used to resect the mass, which, on pathologic examination, proved to be a hamartoma. Hamartomas are non-neoplastic malformations, or inborn errors of tissue development. They are characterized by an abnormal mixture of tissues indigenous to that area of the body. Review of the literature revealed 5 previously reported cases of nasal hamartomas, only 2 of these in children. Our case is unique in that the hamartoma arose from the ethmoid and maxillary sinuses; previously reported cases arose from the septum and vestibule. This is the first reported case treated using a functional endoscopic sinus surgery approach.

Candida laryngotracheitis: a complication of combined steroid and antibiotic usage in croup.

The use of corticosteroids to reduce the morbidity associated with laryngotracheobronchitis (croup) has been a controversial issue for many years. Recent literature, however, does support a decreased morbidity and increased clinical response when short-term steroids are used. As a prophylactic measure against bacterial superinfection, antibiotics are commonly utilized in the treatment of croup. We present the case of an otherwise healthy infant with severe croup who was hospitalized and treated with both steroids and antibiotics. A relapse in her symptoms led to the diagnosis of candida laryngotracheitis. We recommend close monitoring of patients with croup treated aggressively with steroids and antibiotics. Steroid use should be limited to 24 h with antibiotics reserved for patients with signs of bacterial infection.

Tongue gastric choristoma: failure to localize by technetium-99m pertechnetate scan.

Congenital rests of gastric epithelium have been reported in a variety of head and neck locations. Presenting symptoms of these lesions range from an asymptomatic cyst to one which is compromising the airway. The true diagnosis is rarely suspected prior to excision. A case of a gastric choristoma of the tongue is presented which was noted at birth as an intermittently bleeding ulcer. Complete excision of the mass was difficult to ascertain due to poor delineation of the tumor margins from the tongue musculature. A postoperative technetium-99m pertechnetate scan failed to demonstrate residual gastric mucosa. Conservative management resulted in only transient healing of the ulcer. Repeat excision demonstrated abundant residual gastric mucosa. Technetium-99m pertechnetate scanning may not be a reliable indicator of ectopic gastric mucosa in the head and neck region.

Congenital abnormalities of the submandibular duct.

Five newborns presented with cystic lesions of the floor of mouth. Four of these patients proved to have congenitally imperforate submandibular salivary gland ducts and the other newborn proved to have a duplication anomaly of the submandibular gland duct and gland. The patients with imperforate Wharton's ducts underwent marsupialization with or without ductoplasty and have been without evidence of recurrence for up to three years. The duplication anomaly of the submandibular gland duct responded to simple excision. The diagnosis of congenital anomalies of the submandibular gland and duct can be made on physical examination. Magnetic resonance imaging can be helpful in differentiating congenital imperforate submandibular duct and duplication anomalies of the ductal system. Treatment of the former consists of duct marsupialization in the floor of mouth with or without ductoplasty. Treatment of the duplicated ductal system may best be treated with excision. A failure in diagnosis and treatment may result in ranula formation or sialoadenitis requiring more extensive therapy.

Pediatric airway manifestations of gastroesophageal reflux.

Gastroesophageal reflux (GER) in children may be classified as physiologic or pathologic, depending on its degree and consequences. There are many head and neck complications of GER in pediatric patients, but most numerous are the airway manifestations, including stridor, recurrent croup, exacerbation of subglottic stenosis, laryngeal irritation with or without laryngospasm, chronic cough, and obstructive apnea. Diagnosis may be difficult unless there is a high index of suspicion for GER and awareness of the concept of "silent" GER. We present the common pediatric airway manifestations of GER, illustrated by case reports, and provide a paradigm to assist in the diagnosis and management of children with airway compromise associated with GER.

Practical aspects of managing non-malignant lumps of the neck.

The etiologies of pediatric neck masses are legion. Optimal management depends upon making the correct diagnosis. A detailed history to ascertain the duration of the illness, presence of systemic symptoms, animal exposures, tuberculous contacts, medications ingested, recent trauma, dental work or upper respiratory infection (URI), as well as a travel history, may yield important clues to establishing the diagnosis. The work-up for neck masses must be individualized based upon history and physical examination. Common diagnostic studies often obtained are listed in Table 1, and will be further clarified as individual diagnoses are discussed.

One-stage laryngotracheoplasty.

This article documents the evolution of our approach to the repair of subglottic stenosis in infants. With increasing experience in the management of subglottic stenosis using the anterior cricoid split procedure, we extended our procedure to include older children. This then led to the use of the one-stage procedure for repair of severe and mature subglottic stenosis. We present the results of surgical repair in 13 patients. Extubation was accomplished in 12 of 13 patients using one-stage laryngotracheoplasty.

The prognostic value of endotracheal tube-air leak following tracheal surgery in children.

In an effort to determine if the endotracheal tube-leak pressure has prognostic value in relation to a successful outcome after one-stage laryngotracheal reconstruction or cricoid split surgery, a retrospective analysis was performed on 17 children who had undergone such surgery. The daily leak pressures, length of intubation, and ultimate outcome of attempts at extubation were noted. One hundred percent of patients with a leak pressure of less than 20 cm H2O on the day before extubation were successfully extubated. In contrast, the failure rate was 100% in children extubated with a leak of greater than 30 mm H2O. The difference between these two groups was statistically significant (chi 2, 13.03). Sixty percent of patients with leak pressures in the range of 21 to 30 cm H2O were successfully extubated. The endotracheal tube-leak pressure is a parameter that has prognostic value, and should be considered in determining when to extubate children who have undergone tracheal reconstructive surgery.

Actinomycosis in obstructive tonsillar hypertrophy and recurrent tonsillitis.

A quantitative analysis of adenoid and tonsillar specimens from 460 patients was performed. The patients underwent tonsillectomy or adenotonsillectomy for either recurrent tonsillitis or obstructive tonsillar hypertrophy. Histologic preparations revealed Actinomycetes as statistically more prevalent in the obstructive population. The presence of Actinomycetes in the adenotonsillar core of this diagnostic group may indicate an etiologic role for this organism in tonsillar and adenoidal hypertrophy.

The open surgical approach to subglottic hemangioma.

The management of subglottic hemangioma in infants remains controversial. We report two patients in whom an open surgical approach was utilized to completely excise the subglottic hemangioma. Both children have been successfully extubated and have remained symptom-free since that time.

Closure of the soft palate for persistent otorrhea after placement of pressure equalization tubes in cleft palate infants.

Four case reports of infants with cleft palate and intractable otorrhea following the placement of pressure equalization tubes are presented. In one patient, liquids taken orally were noted to reflux through her ears. Otorrhea was refractory to medical management in all cases and was controlled only after closure of the soft palate. Persistent otorrhea may be an indication for early closure of the soft palate in these infants.

Current concepts in pediatric adenotonsillar disease.

More objective thinking regarding the indications for adenotonsillar surgery has gained new respect for these operations. Better understanding of the implications of adenoid disease in chronic otitis and sinusitis, along with appreciation of obstructive airway problems secondary to adenotonsillar hypertrophy, has changed the scope of the operation. Research is ongoing to determine the etiology of chronic antigenic stimulation as a cause for hypertrophy of these organs.

The otolaryngologic manifestations of Pelizaeus-Merzbacher disease.

Pelizaeus-Merzbacher disease is a condition of central nervous system dysmyelination. We describe a familial series in which both otologic and laryngologic abnormalities were present. The diagnosis of this invariably fatal disorder can be made on a clinical and/or pathologic basis. As the otolaryngologic manifestations are often the first to appear, the consulting head and neck surgeon may be essential in the initial diagnosis of this hereditary disease.

Do angiomas of the nasal septum exist?

Juvenile nasopharyngeal angiofibromas (JNA) by definition originate in the nasopharynx. Vascular tumors arising in the nasal cavity can easily be mistaken for JNA, when the correct diagnosis is hemangioma or angiofibromatous polyp. We present a case that illustrates this problem, an 11-year-old boy with a unilateral anterior nasal cavity mass associated with recurrent epistaxis. At surgery, the mass was found to arise from the anterior nasal septum and was removed easily with minimal bleeding. The initial pathologic interpretation was JNA. After extensive review of the specimen, however, the diagnosis of hemangioma was made. Similar tumors have been reported as being JNA that have been simple to remove with minimal blood loss. JNA is associated with more severe blood loss, is more difficult to expose surgically and has a higher risk of recurrence than other nasal tumors. Therefore, JNA needs to be distinguished from anterior nasal cavity masses.

Catheterization of branchial sinus tracts. A new method.

The complete surgical extirpation of branchial cleft abnormalities is essential in avoiding recurrent disease. The most technically difficult maneuver is often the localization and excision of associated sinus tracts and fistulae. The authors communicate a simple yet effective technique for dealing with this difficulty utilizing the Fogarty embolectomy catheter.

Early home management of patients with Pierre Robin sequence.

Robin Sequence is a well-described disorder with a reported incidence of 1 in 2000 births. It is characterized by glossoptosis and micrognathia often associated with a cleft palate. Respiratory obstruction at the level of the tongue occurs in many affected children. Prior to routine intensive care unit management, it was the primary factor in the mortality reported in patients with moderately severe to severe deformity. Treatment of this obstruction is controversial and may include a long stay in an intensive care setting. We report two cases that demonstrate properly placed and constructed nasopharyngeal tubes allow a non-surgical treatment with early discharge of the patient and without the risks and morbidity of surgery or the complications of tracheostomy.
