Endoscopic sinus surgery in children with chronic sinusitis: A pilot study

This pilot study assessed the safety and preliminary data on the efficacy of endoscopic ethmoidectomy in children with chronic sinusitis. A total of 168 patients were evaluated for chronic sinusitis, and 31 were deemed appropriate candidates for ethmoidectomy. All patients were medical management failures. Twenty‐six percent of the patients had asthma, 23% had some immune deficiency, 23% had allergies, and 2 patients (1%) had cystic fibrosis. All patients were followed for at least 1 year postoperatively. The only surgical complication was minor middle meatal scarring that developed in two patients. Overall, 71% of the patients were considered normal by their parents 1 year postoperatively. Of the 24 patients who did not have an underlying systemic disease (immune deficiency or cystic fibrosis) postoperatively, 80% were considered normal by their parents, 12% were improved but continued to have some symptoms, and 8% had unsatisfactory results. Seven children with underlying systemic disease had to undergo revision ethmoidectomy for persistent symptoms.

Long-term outcome of facial growth after functional endoscopic sinus surgery

OBJECTIVE: We sought to determine whether functional endoscopic sinus (FES) surgery performed in children with chronic rhinosinusitis alters facial growth. STUDY DESIGN AND SETTING: This was a retrospective age-matched cohort outcome study performed at a tertiary care hospital. RESULTS: Sixty-seven children participated. There were 46 boys and 21 girls, and the mean age was 3.1 years at presentation and 13.2 years at follow-up. There were 46 children who underwent FES surgery and 21 children who did not undergo FES surgery. Quantitative anthropomorphic analysis was performed using 12 standard facial measurements. A facial plastic expert performed qualitative facial analysis. Both quantitative and qualitative analyses showed no statistical significance in facial growth between children who underwent FES surgery and those who did not undergo FES surgery. CONCLUSIONS: In this study, there was no evidence that FES surgery affected facial growth. SIGNIFICANCE: These results will aid physicians when discussing with parents the risks of FES surgery.

Medical management of chronic suppurative otitis media without cholesteatoma in children

Tympanomastoid surgery is considered standard management for chronic suppurative otitis media (CSOM) without cholesteatoma, which is unresponsive to ototopical/oral antimicrobial therapy. The following makes this sequence of management less attractive today: 1. potential ototoxicity of ototopical agents; 2. lack of oral antimicrobial agents effective against most common pathogens (e.g., Pseudomonas aeruginosa); 3. frequent occurrence in children who have tympanostomy tubes; and 4. failure of tympanomastoid surgery to eradicate the disease in all cases. We conducted a study in 36 pediatric patients with chronic suppurative otitis media, in which all received parenteral antimicrobial therapy and daily aural toilet (mean duration of treatment = 9.7 days). Thirty‐two patients (89%) had resolution of their infection with medical therapy alone; four children required tympanomastoidectomy. Further investigation is needed to understand the etiology, pathogenesis, and most effective methods of management/prevention of CSOM in children.

Comparison of vasoconstrictors for functional endoscopic sinus surgery in children

Three different vasoconstricting agents were evaluated during functional endoscopic sinus surgery (FESS) in 57 children. Oxymetazoline hydrochloride 0.05%, phenylephrine hydrochloride 0.25%, or cocaine 4% was applied to the nasal mucosa in a prospective, randomized, double‐blind fashion. Heart rate and blood pressure changes were recorded 5 and 10 minutes after application of the study vasoconstrictor to each nostril. The surgeons subjective impressions of bleeding and visualization were recorded for each side of the nose, as were total blood loss and anesthesia time. Although all three vasoconstrictors were tolerated well by the children, there was a suggestion that heart rate decreased more at 5 minutes with phenylephrine than with oxymetazoline or cocaine (P = .08) and that blood pressure increased more at 10 minutes with phenylephrine than with oxymetazoline or cocaine (P = .1). No arrhythmias were noted. Subjective scoring for bleeding showed that children receiving oxymetazoline were less likely to receive scores of “more” bleeding than usual (3/38 vs. 10/34 for phenylephrine and 10/35 for cocaine, P<.02). Subjective scoring for visualization showed that children receiving oxymetazoline were also less likely to receive scores of “worse” visualization than usual (3/38 vs. 12/38 for phenylephrine and 9/35 for cocaine, P<.01). There was no difference in surgical bleeding or visualization between children receiving phenylephrine and children receiving cocaine. In our institution, 0.05% oxymetazoline is the preferred vasoconstrictor for FESS in children.

Pediatric Sinusitis and Subperiosteal Orbital Abscess Formation: Diagnosis and Treatment

Twenty-two children with subperiosteal orbital abscesses were treated at St. Louis Childrens Hospital between 1983 and 1992. Eighteen patients were otherwise in good health; four patients had cystic fibrosis, mucoceles, or were immunocompromised. All patients were treated with intravenous antibiotics and abscess drainage. CT scans were obtained preoperatively in each case. Ten patients were treated with endoscopic ethmoidectomy and abscess drainage, and 11 were treated with external ethmoidectomy and abscess drainage. One child was initially treated with abscess drainage and an elective endoscopic ethmoidectomy was performed later. There were no cases of permanent visual loss or neurologic sequelae. Culture results were positive in 14 cases and mixed infections were common. Complications included recurrent abscess, cerebritis, and empyema. We recommend combined medical and surgical treatment for all children with subperiosteal orbital abscess. We feel that endoscopic ethmoidectomy and abscess drainage offers some advantages over external ethmoidectomy and abscess drainage.

Management of rhinosinusitis in children

The authors provide definitions for the different forms of pediatric rhinosinusitis, with an enumeration of the main symptoms and signs. They also provide the indications for CT scan examination and microbiological investigations. In addition, they emphasize the importance of concomitant systemic disease, such as allergy and immunological disorders. The adequate medical management, which is mandatory before any surgery, is considered and discussed, and the indications for surgery are provided.

COCHLEAR IMPLANTATION IN CHILDREN WITH INNER EAR MALFORMATIONS

We performed a case study and intervention study, with follow-up of 1 to 5 years, in 4 children with inner ear malformations who underwent implantation of a multichannel cochlear implant (Nucleus, Cochlear Corporation) at ages 3 to 12 years. Malformations included a common cavity deformity, 2 incomplete partitions, and 1 case of isolated bilateral vestibular aqueduct enlargement. One child had a single-channel implant placed at 3 years of age, and this was exchanged for a 22-channel implant at age 9. One child had her implant placed at age 4.5 years, but due to complications from a cerebrospinal fluid (CSF) leak had the initial implant removed and replaced at age 5 years during repair of the CSF leak. Intraoperative findings included a CSF leak at the time of surgery in 3 patients. One patient contracted bacterial meningitis 7 months postimplantation that was thought to be secondary to acute otitis media in the unoperated ear. Bilateral CSF leaks were noted in the middle ear by a lumbar puncture radionuclide and fluorescein dye study. Successful repair of the CSF leaks and reimplantation of the cochlear implant was carried out in this patient. Mapping and programing of the implant was found to be challenging in each of these patients. All patients demonstrated improved performance after implantation. Two patients demonstrated some open-set speech perception. One patient demonstrates improved use of temporal cues in a structured closed set. One patient has achieved no significant speech recognition at this time, but does have improved sound detection and awareness. Cochlear implantation in children with congenital inner ear abnormalities can be a successful method of rehabilitation. It should be recognized that the postoperative speech perception results may be highly variable among patients, and that intraoperative complications may occur.

The diagnosis and treatment of recurrent and chronic sinusitis in children

Pediatricians, allergists, family practitioners and otolaryngologists are all very aware of the increasing problem of recurrent and chronic sinusitis in children. This article details the diagnosis and management of the disease process and outlines steps for its future management.

Auricular Cartilage Grafts in Laryngotracheal Reconstruction

Introduction of the anterior cricoid split (decompression) and laryngotracheal reconstruction with costal cartilage graft has resulted in the successful management of many cases of subglottic stenosis. However, the procedure does not allow uniform extubation, and laryngotracheal reconstruction with costal cartilage may be too aggressive for neonates. We have explored the use of autogenous auricular cartilage graft in laryngotracheal reconstruction. Its high rate of success and low morbidity have enabled us to expand the indications. We report our experience in 23 patients with auricular cartilage grafts.

Nasal obstruction in the neonate secondary to nasolacrimal duct cysts

The neonate is an obligate nasal breather and any form of nasal obstruction causes respiratory distress during feeding and sleeping. We report two patients with unusual causes of respiratory distress secondary to nasolacrimal duct cysts. The failure of the lacrimal duct to perforate at the distal end results in dacryocystitis and cyst formation. Removal of the nasal wall of the cyst resolves the obstruction and the dacryocystitis. The nasolacrimal duct cyst is an unusual, but readily treated, cause of neonatal respiratory distress.
