Well-differentiated liposarcoma of the epiglottis.

Liposarcomas of the larynx are very rare. A review of the English literature revealed only 28 published reports of tumours in this anatomical location. Diagnosis requires a high index of suspicion and careful histologic analysis. We present a case of a well-differentiated liposarcoma of the epiglottis, the tenth reported case at this laryngeal subsite. Initial biopsy specimens showed histological characteristics of a liposarcoma, which facilitated provision of optimal surgical treatment after careful analysis of published literature.

Management of medial subperiosteal abscess of the orbit in children--a 5 year experience.

A medial subperiosteal abscess (SPA) of the orbit is the most common serious complication of sinusitis in children. The distinction between SPA and the more benign pre-septal disease is difficult to make especially in a young child in whom an ophthalmological evaluation is often difficult. Computerised tomography (CT) is the investigation of choice in making this distinction. Subperiosteal inflammatory disease of the orbit is initially treated with intravenous antibiotic therapy with surgery reserved for those patients who do not respond to medical treatment and in whom a medial SPA is confirmed by CT. Conventionally, the abscess is drained via an external incision and an ethmoidectomy is performed at the same time. More recently, successful drainage of SPA's has been accomplished endoscopically via a intranasal approach with less morbidity and superior cosmesis. We present a 5 year experience of 24 patients with CT scans suggestive of medial SPA who underwent endoscopic exploration of the medial subperiosteal orbital space. We discuss the current management of medial subperiosteal disease of the orbit in children and include a review of the literature. Also included is a clinical staging system which aids the management of orbital complications of sinusitis.

Peritonsillar abscess in early childhood. Presentation and management.

OBJECTIVE: To highlight the modes of presentation and management of a peritonsillar abscess in children younger than 5 years. DESIGN: Retrospective case series. SETTING: Tertiary referral pediatric otolaryngology practice. PATIENTS: Seven children younger than 5 years. RESULTS: The mean age of the children studied was 27 months (age range, 7-41 months). Five (71%) of the 7 patients underwent computed tomographic scanning to confirm the diagnosis. Pus was cultured at surgery in every case. The most common organism detected was Streptococcus viridans. The average hospital stay was 72 hours (range, 22 hours to 12 days). After diagnosis of an abscess, all patients underwent an electrocautery tonsillectomy and had an uneventful recovery. CONCLUSIONS: Children younger than 5 years who present with poor oral intake, high fever, drooling, and trismus should be suspected of having a peritonsillar abscess. A computed tomographic scan of the neck is usually required to confirm a suspected diagnosis. Prompt diagnosis and treatment will lead to a considerable decrease in morbidity. Immediate tonsillectomy is a safe and effective means of abscess drainage.

Outpatient adenotonsillectomy. Is it safe in children younger than 3 years?

OBJECTIVE: To evaluate the safety of ambulatory adenotonsillectomy in children younger than 3 years. MATERIALS AND METHODS: The records of 102 children younger than 3 years who underwent adenotonsillectomy as an outpatient procedure were reviewed during a 3-year period. RESULTS: Ten patients (10%) required overnight hospital admission for an average of 1.4 days. Nine patients were admitted directly from the day-stay unit and 1 patient was admitted 48 hours after surgery. The reason for hospital admission was poor oral intake. None of the patients had postoperative bleeding or respiratory problems or required intensive care unit admission. CONCLUSION: The safety of ambulatory adenotonsillectomy depends on judicious selection criteria and can be performed in children younger than 3 years.

Fat graft myringoplasty in children--a safe and successful day-stay procedure.

The surgical closure of dry tympanic membrane perforations in children remains a controversial issue due to conflicting opinions on the appropriate technique, graft material and success rate. We present a review of 342 children who underwent fat graft myringoplasty as a day-stay procedure over a six-year period. Successful closure of the tympanic membrane perforation was achieved in 92 per cent of ears. Subsequent recurrent otitis media with effusion required insertion of ventilation tubes in 12 per cent. No relationship was observed between the age of the child and a successful outcome. We conclude that day-stay fat graft myringoplasty is a safe and successful procedure which results in a dry and safe ear in the majority of children.

Pediatric functional endoscopic sinus surgery: is a second look necessary?

Functional endoscopic sinus surgery (FESS) has become the surgical procedure of choice for the treatment of chronic sinusitis that is refractory to medical treatment. It has become routine to perform endoscopy in children under general anesthesia 2 to 3 weeks after FESS to facilitate examination and cleaning of the operative site. We compared the clinical outcome of 50 children who underwent FESS without a second-look endoscopy with 50 children who underwent a routine second look. Patients with systemic disease (cystic fibrosis, immotile ciliary syndrome, immunoglobulin deficiency) or undergoing a revision procedure were excluded from the study. The results show that the postoperative improvement in nasal obstruction, nasal drainage, and chronic cough was the same for both groups. We conclude that in the vast majority of children without systemic disease and not undergoing a revision procedure, a second endoscopic procedure may not offer any apparent advantage.

Subglottic stenosis complicating cardiac surgery in children.

OBJECTIVE: To highlight the incidence of subglottic stenosis (SGS) as a complication of surgery for congenital heart disease and the role of single-stage laryngotracheoplasty in treating this complication. DESIGN: Retrospective case series. SETTING: University-based referral center specializing in surgery for congenital heart disease and complex airway problem management. INTERVENTION: Laryngotracheal reconstruction (LTR). MAIN OUTCOME MEASURE: Successful airway expansion. RESULTS: At last follow-up, 87.5% (7 of 8) of patients remain free of obstructive airway symptoms. CONCLUSION: SGS can complicate surgery for congenital heart disease in children. Single-stage LTR is an effective treatment modality for this problem.

Pseudoaneurysm of the right lingual artery: an unusual cause of severe hemorrhage during tonsillectomy.

Profuse intraoperative hemorrhage is an uncommon complication of tonsillectomy. We present a three-year-old girl who underwent a routine adenotonsillectomy during which massive bleeding occurred from a large vessel in the right tonsillar fossae. Angiography revealed an aberrant right lingual artery with a pseudoaneurysm. The right lingual artery was embolized with multiple coils and the bleeding was halted. The causes and treatment of extracranial carotid artery pseudoaneurysms are discussed.

Campomelic syndrome--laryngotracheomalacia treated with single-stage laryngotracheal reconstruction.

The campomelic syndrome is a rare osteochondrodysplasia which frequently leads to early death from pulmonary insufficiency. We describe a patient with anatomic compromise of the upper airway due to diffuse laryngotracheomalacia and a moderate subglottic stenosis, treated successfully with single-stage laryngotracheal reconstruction using a rib graft. To our knowledge this has not been previously described. A review of the current literature is included.

Disability after labyrinthectomy.

A labyrinthectomy is known to relieve vertigo successfully in the majority of patients who suffer from Menière's disease and have non-serviceable hearing in the affected ear. It is assumed that the procedure reduces disability, helps the patient to return to work and improves the quality of life. Eighteen patients who underwent a transmastoid drill-out labyrinthectomy between 1980 and 1990 were interviewed and an attempt was made to evaluate the success of the operation in accordance with the guidelines set out by the AAO-HNS 1985. In the present series it was noted that although vertigo was relieved in 89 per cent of patients after labyrinthectomy, only 50 per cent of them returned to work. In this study, the age and occupation of the patient at the time of surgery and the relief of vertigo did not accurately predict whether or not a patient returned to work.

Bilateral fat graft myringoplasty in children.

The results after simultaneous bilateral fat graft myringoplasties in children have not been previously reported in the literature. We report on 28 children who underwent bilateral fat graft myringoplasties as outpatient procedures under general anesthesia. The success rate was 91% at final follow-up, with only 16% of children requiring insertion of pressure-equalizing (PE) tubes following surgery. No complications were documented. We concluded that bilateral fat graft myringoplasties are safe to perform, with an excellent success rate, and are suitable as outpatient procedures.
