Acute respiratory compromise resulting from tracheal mucous impaction secondary to a transtracheal oxygen catheter.

Transtracheal oxygen catheters are being increasingly used because of savings in oxygen usage and patient preference. The complications of the catheter are believed to be minor and easily managed. Inspissated mucous collections that form at the tip of the SCOOP 1 (Transtracheal Systems, Denver, Colorado) catheter have been reported but are usually easily expectorated by the patient. This report describes a patient who had development of acute respiratory compromise from crusted mucoid impaction of the trachea secondary to transtracheal catheter use. General anesthesia and rigid bronchoscopy were required for removal of the obstructing impaction. Unexplained worsening of respiratory symptoms in patients with transtracheal oxygen catheters should be addressed by prompt stripping of the catheter.

Tenuous airway in children with trisomy 21.

Multiple congenital anomalies are closely linked to Down syndrome (trisomy 21). Cardiac malformations are found in 40% of patients, a large number of whom will require a major surgical procedure. The importance of postextubation stridor in these children is frequently underestimated. A retrospective review of 99 trisomy 21 patients who underwent cardiovascular surgery revealed postextubation stridor in 24 (24.2%). Significant factors for the development of stridor included younger age (P=0.04), lower growth percentile for weight (P=0.03), and increased frequency of reintubation (P=0.04). Subglottic stenosis was found in 6 (6.1%). In 4 of these patients, an endotracheal tube of larger diameter than predicted for age was used. All 6 patients were less than the 10th percentile for weight. We conclude that Down syndrome patients deserve special considerations and modifications of standard intubation techniques for successful airway management.

Acquired nasopharyngeal stenosis: a warning and review.

OBJECTIVES: To present and discuss the clinical presentation and treatment planning in children with acquired nasopharyngeal stenosis (NPS) following tonsillectomy and adenoidectomy. DESIGN: Case series. SETTING: Tertiary care center. PATIENTS AND OTHER PARTICIPANTS: Nine children identified over 2 years (1995-1996) with newly diagnosed NPS were evaluated. Seven of these children underwent adenoidectomy using a potassium titanyl phosphate laser technique at a neighboring facility. These children were aged 15.6 to 62.1 months at the time of original surgery, and all presented with nasal obstruction and mouth breathing beginning within 10 weeks after surgery. In addition, 5 had newly documented obstructive sleep apnea. RESULTS: Of the 9 children, 1 required a tracheotomy. After undergoing an adenoidectomy, chronic rhinosinusitis developed and aggressive medical treatment failed in 4 children. Time from symptom onset to diagnosis of NPS ranged from 2 to 34 months. The diagnosis of NPS depends on obtaining a thorough medical history and conducting a physical examination that includes nasopharyngoscopy. Most children underwent a computed tomographic scan prior to repair. The scarring encountered in these patients involved the soft palate and the posterior pharyngeal wall and/or choanae bilaterally. Five children had no identifiable eustachian tube opening into the nasopharynx, and all 5 children had chronic otitis media with effusion or persistent otorrhea. CONCLUSIONS: Nasopharyngeal stenosis following adenoidectomy and/or tonsillectomy is difficult to correct. Multiple surgeries may be required to relieve the obstruction. Standard operative techniques using the lateral pharyngeal flap and transpalatal or endoscopic intranasal approaches were adapted to the clinical situation. Prolonged use of nasal stents is mandatory to produce a nasopharyngeal opening. Adjunctive treatment may include pressure equalization tubes. However, the best treatment remains prevention.

Surgical management of macroglossia in children.

Congenital macroglossia is associated with a variety of syndromes, most commonly Down syndrome and Beckwith-Widemann syndrome. Clinically, macroglossia may result in respiratory compromise, dysphagia, and poor cosmesis. A variety of treatments have been proposed, with surgical resection being the most common. We review management and describe a new surgical technique, consisting of a keyhole resection to decrease the width and length of the tongue. Between 1990 and 1992, five keyhole resections for congenital macroglossia were performed on four consecutive children at Texas Children's Hospital, Baylor College of Medicine, Houston. Patients had improved cosmesis and improved function of the oropharyngeal airway, with no change in speech and feeding. Keyhole resection is an effective treatment for macroglossia.

Intralesional cidofovir for recurrent respiratory papillomatosis in children.

OBJECTIVE: To assess the potential benefit of intralesional administration of cidofovir, an acyclic nucleoside phosphonate with activity against several DNA viruses, for treating severe respiratory papillomas in pediatric patients. DESIGN: Prospective case series. SETTING: Tertiary care children's hospitals. PATIENTS: Five pediatric patients with severe recurrent respiratory papillomatosis requiring laryngoscopy with carbon dioxide laser therapy more frequently than once a month to maintain airway patency. Each patient underwent between 12 and 33 laryngoscopies with laser treatment prior to being injected with cidofovir. INTERVENTION: Microsuspension laryngoscopy with intralesional injection of cidofovir (Vistide) in conjunction with mechanical debulking and carbon dioxide laser of papillomas. MAIN OUTCOME MEASURE: Papilloma stage at time of serial laryngoscopies. RESULTS: One patient was disease free and 3 patients demonstrated a dramatic response to adjuvant therapy with cidofovir at the 9-month follow-up visit after the last injection of cidofovir. One patient showed an improvement in papilloma stage that was possibly related to concurrent therapy with interferon. CONCLUSIONS: Intralesional injection of cidofovir seems to be of benefit in the treatment of severe respiratory papillomatosis in pediatric patients. Larger prospective studies with longer follow-up will be required before cidofovir can be considered an accepted means of managing this difficult disease.

Head and neck manifestations of erythema multiforme in children.

Erythema multiforme, Stevens-Johnson syndrome, and toxic epidermal necrolysis are related disorders of skin and mucous membranes, which are typically associated with antecedent medication use or infection. We review 108 cases of erythema multiforme, Stevens-Johnson syndrome, and toxic epidermal necrolysis from Texas Children's Hospital, Houston, Texas, from 1981 to 1991, and illustrate the characteristic skin and mucosal lesions. In addition, we describe in detail two unusual cases requiring intensive airway management. Head and neck manifestations were present in 4 of 79 patients (5%) with erythema multiforme and 26 of 28 patients (93%) with Stevens-Johnson syndrome. In Stevens-Johnson syndrome, mucosal involvement of the lip (93%), conjunctiva (82%), oral cavity (79%), and nose (36%) were most common. Antecedent medication use was identified in 59% of erythema multiforme patients and 68% of Stevens-Johnson syndrome patients. We note a striking increase in the number of cases in our series caused by cephalosporins. Fifty percent of Stevens-Johnson syndrome patients required supplemental hydration or alimentation because of the severity of the oral cavity involvement. The head and neck mucosal manifestations largely respond to local care, and the routine use of prophylactic antibiotics or systemic steroids is not recommended.

Gunshot injuries of the temporal bone.

Concurrent with the increase in handgun crime in the United States is a rising incidence of gunshot wounds to the temporal bone. These injuries present challenging diagnostic and management problems to the otolaryngologist. A timely multicenter review of this entity revealed 22 cases evaluated and treated by the authors between 1975 and 1984. A wide variety of injuries were encountered, involving anatomic structures within or contiguous with the temporal bone. These included: eight intracranial injuries; 11 traumatized facial nerves; seven vascular wounds; 19 mastoid, middle, or inner ear injuries; and 11 cases of damage to the external auditory canals. A rational scheme for immediate and long-term management of each type of injury is outlined. Illustrative cases representing vascular, neural, temporal bone, and central nervous system injury are presented.

Hypothyroidism following radiotherapy for head and neck cancer.

Hypothyroidism is not commonly considered a complication of radiotherapy for head and neck cancer. A series of 96 patients treated with radiotherapy alone or combined with surgery for head and neck cancer was retrospectively studied. All patients had radiation ports that included the thyroid gland. Hypothyroidism after radiotherapy was documented in 26% of all patients. The majority of patients had subclinical hypothyroidism manifested by elevated thyroid-stimulating hormone (TSH) levels. The incidence of hypothyroidism dramatically increased to 65% when radiotherapy was combined with surgery that included a partial thyroidectomy. In addition, we report the unusual occurrence of massive head, neck, and hypopharyngeal edema caused by severe hypothyroidism in two patients. We advocate routine monitoring of head and neck cancer patients for hypothyroidism after radiotherapy involving the thyroid gland and recommend levothyroxine replacement therapy for subclinical hypothyroidism.

Is parental perception an accurate predictor of childhood hearing loss? A prospective study.

OBJECTIVE: We performed this study to assess whether parental perception of hearing loss predicted the results of audiometric testing in children with recurrent otitis media or persistent otitis media with effusion. METHODS: As part of a larger prospective observational outcomes study of children undergoing tympanostomy tube placement, the child's parent completed a standardized questionnaire before and after tube placement. In addition, patients underwent age-appropriate audiologic threshold and tympanometry testing before and after tube placement. RESULTS: We enrolled 113 patients (median age, 2 years), and 93 (82%) completed follow-up. Before treatment, parental perception of hearing loss did not predict hearing threshold level. After tube placement, parental perception of hearing loss was also poorly correlated with change in threshold. CONCLUSIONS: Parental perception of their child's hearing loss is a poor predictor of objective audiologic findings both before and after treatment with tympanostomy tubes. These findings have important implications concerning the importance of screening for hearing loss in children with otitis media with effusion.

Stapedectomy trends for the resident.

The diminishing number of cases of otosclerosis limits the training experience in stapes surgery during residency. Results are suboptimal. Closure of the preoperative air conduction to within 10 dB of bone conduction was obtained in only 64% of resident cases. Efforts to maximize experience and improve results include closer faculty supervision, use of one stapedectomy technique, and a prospective study of individual residents' performance.

Choanal atresia and associated anomalies: the CHARGE association.

Over the past few years there has been increasing awareness of the association of choanal atresia with other congenital defects. Thirty-one cases of choanal atresia were reviewed and other congenital anomalies were documented in 19 patients. These other anomalies were identified in 75% of the 20 patients with bilateral choanal atresia but in only 36% of the 11 patients with unilateral choanal atresia. Associated defects largely occurred in a predictable pattern described by the CHARGE mnemonic: C-coloboma, H-heart disease, A-atresia choanae, R-retarded growth, G-genital hypoplasia, E-ear defects. The implications of the CHARGE association in the management of patients with choanal atresia are discussed.

Gastroesophageal reflux association with laryngomalacia: a prospective study.

OBJECTIVE: To identify the incidence and clinical role of gastroesophageal reflux (GER) in patients with laryngomalacia. DESIGN: Prospective evaluation of consecutive infants with a new diagnosis of laryngomalacia with an initial questionnaire, a barium esophagram or 24 h pH probe and record of their subsequent clinical course. SETTING: A large, tertiary pediatric referral center and its associated outpatient clinic. PATIENTS: New diagnosis of laryngomalacia in 33 consecutive infants were evaluated by questionnaire and 27 of these were evaluated for GER. RESULTS: GER was observed in 64% of patients and was significantly associated with severe symptoms and complicated clinical course (P = 0.0163). The presence of smokers in the infant's household negatively impacted his or her clinical course and symptomatology (P = 0.013) as did the presence of other major, concurrent medical problems (P = 0.065). CONCLUSIONS: In patients with laryngomalacia, GER was significantly associated with severe symptoms (a complicated clinical course), as was smoking in an infant's household and other significant medical problems.

Incidental finding of an intranasal foreign body discovered on routine dental examination: case report.

A nasal foreign body was discovered radiologically on an initial dental examination of a young child. The child was a candidate for dental rehabilitation, using nasotracheal intubation under general anesthesia. The parents were unaware of the object's presence, and the child had no nasal symptoms. The child was referred to the Otolaryngology-Head and Neck Surgery Service to have the object removed; this was accomplished successfully without sequelae on an outpatient basis. Dentists and physicians who treat children should be alert to the possible presence of intranasal objects in their patients.

Paranasal sinus development in chronic sinusitis, cystic fibrosis, and normal comparison population: a computerized tomography correlation study.

Chronic sinus disease in patients with and without cystic fibrosis may have an impact on the pattern of paranasal sinus pneumatization. Arrest of pneumatization has been reported in both of these conditions. To assess the development of the paranasal sinuses in relationship to chronic sinusitis and cystic fibrosis (CF), a retrospective review of coronal CT scans of the age-matched patients with no previous sinus disease, patients with chronic sinusitis, and cystic fibrosis patients was conducted. The patients' ages ranged from 4 to 17 years. The maxillary sinus volume, anteroposterior diameter, and greatest transverse diameter and height were determined using image analysis software after the coronal CT scans were scanned into Macintosh computer. The size of the maxillary sinus increased with advancing age in the control and chronic sinusitis group, but not in the patients with cystic fibrosis. The patients with cystic fibrosis had a statistically significant smaller maxillary sinus size. Approximately 50% of the patients with chronic sinusitis had anatomic anomalies, the most common being paradoxical middle turbinates. The CT scans of CF patients were characterized by uncinate process demineralization and medial displacement of the lateral nasal wall in the middle meatus, and decreased maxillary sinus pneumatization.

Acute-phase reactants and acute bacterial otitis media.

OBJECTIVE: To determine if the erythrocyte sedimentation rate and C-reactive protein level are elevated in uncomplicated acute bacterial otitis media. DESIGN: Investigator-blinded, antibiotic efficacy trial. SETTING: The emergency department of an urban regional children's hospital with 24,000 annual visits. PARTICIPANTS: Thirty-one children with symptoms of acute bacterial otitis media of 7 days' duration or less. SELECTION PROCEDURE: Volunteer sample. INTERVENTIONS: Tympanocentesis, oral antibiotics for 10 days, and three follow-up visits in the next 30 days. MEASUREMENTS/RESULTS: The erythrocyte sedimentation rate and C-reactive protein level were obtained at time of entry into the antibiotic study. Seventeen patients (55%; 95% confidence interval, 37% to 72%) had either an erythrocyte sedimentation rate above 20 mm/h or a C-reactive protein level above 8 mg/L. Eleven patients (35%) had a recurrent episode of acute bacterial otitis media during the follow-up period. The relative risk of recurrence of otitis media given an elevated erythrocyte sedimentation rate or C-reactive protein level was 8.24 (95% confidence interval, 1.20 to 56.74; Fisher's Exact Test; P = .007). CONCLUSIONS: Clinicians who use elevated acute-phase reactants as possible indicators of invasive bacterial infections should be aware that an elevated erythrocyte sedimentation rate or C-reactive protein level is also consistent with acute bacterial otitis media. An elevated erythrocyte sedimentation rate or C-reactive protein level also appears to be associated with an increased risk of recurrence of acute bacterial otitis media. If these findings can be confirmed in a larger study, the erythrocyte sedimentation rate or C-reactive protein level could be used to assess the risk of recurrent otitis media.

Bacteriology of acute otitis media: a new perspective.

Pathogenic bacteria were isolated from 90% of patients with acute otitis media. This higher-than-expected rate of positive cultures was probably related to the meticulous bacteriologic techniques used.
