Orbital complications of sinusitis in children.

BACKGROUND Orbital complications of sinusitis are uncommon but can result in significant morbidity if not appropriately managed. OBJECTIVE This study was conducted to evaluate the clinical presentation, diagnosis, management, and outcome of orbital complications of sinusitis in children treated at our institution over a 10-year period. METHODS The study retrospectively reviewed cases of 139 children with evidence of orbital complications of sinusitis admitted to the Montreal Childrens Hospital between January 1990 and March 2000. Factors assessed included the clinical presentation, radiologic findings, management, and outcome (length of admission, complications). Complications were classified as preseptal if they did not penetrate the periorbita. Postseptal complications were defined as those penetrating the periorbita and were further subdivided into cellulitis and abscess categories. RESULTS Seventy-two percent of patients presented with preseptal cellulitis, 19% with orbital cellulitis, and 9% with subperiosteal abscess. Ophthalmoplegia and proptosis at presentation were found to be predictors of postseptal disease, although computed tomography (CT) was necessary to differentiate between cellulitis and abscess. Preseptal disease resolved with antibiotics in all cases. Postseptal disease was treated medically and in some cases surgically, although surgery did not affect outcome. CONCLUSION Preseptal complications of sinusitis can be diagnosed clinically without a CT scan and should be treated with an appropriate course of intravenous antibiotics. Postseptal complications of sinusitis can be diagnosed by the presence of ophthalmoplegia or proptosis and mandate a CT scan to differentiate abscess from orbital cellulitis. Management of these patients should include intravenous antibiotics, reserving surgery for selected cases.

Lateral Sinus Thrombosis as a Complication of Otitis Media: 10-Year Experience at the Children's Hospital of Philadelphia

OBJECTIVES. Lateral sinus thrombosis is a rare intracranial complication of otitis media that is traditionally described in countries with poor access to medical care. Our goal was to describe the clinical presentation, management, and outcome of patients diagnosed with lateral sinus thrombosis in a US tertiary care center and to highlight the clinically relevant differences in presentation between these patients and those described in previous reports. PATIENTS AND METHODS. The medical charts of 13 patients diagnosed with otogenic lateral sinus thrombosis were reviewed. These patients were identified from a manual search of 156 subjects with International Classification of Diseases, Ninth Revision codes corresponding with a diagnosis of mastoiditis or thromboembolism over a 10-year period (1997–2007) at the Childrens Hospital of Philadelphia. RESULTS. In contrast to previous reports in the literature, the majority of patients in this series exhibited cranial neuropathies and signs of raised intracranial pressure. Nearly all of the patients had a history of acute otitis media treated with antibiotics in the weeks preceding admission. However, many patients denied high fevers or active otomastoid symptoms, which are classically associated with lateral sinus thrombosis. The diagnosis was made in all of the children by using computed tomography and MRI/venography. Treatment strategies included myringotomy tube placement, simple mastoidectomy, intravenous antibiotics, and anticoagulation. Posthospitalization follow-up data revealed no significant long-term complications. CONCLUSIONS. Despite appropriate antibiotic therapy, lateral sinus thrombosis and other intracranial complications of otitis media are still a threat to children in the modern era. Neurologic, rather than otologic, symptoms may dominate the presentation of otogenic lateral sinus thrombosis. Thus, a high index of suspicion may be critical for ensuring timely diagnosis of this rare condition.

Epiglottitis and Croup

Infections of the upper airways are a frequent cause of morbidity in children. Viral laryngotracheobronchitis (croup) is the most common cause of stridor in children and usually has a self-limited course with occasional relapses in early childhood. Epiglottitis has become rare in developed countries with the advent of universal vaccinations against Haemophilus influenzae. It can be rapidly fatal, however, if not promptly recognized and appropriately managed. This article reviews the pathogenesis, epidemiology, clinical presentation, diagnosis, and management of these pediatric upper airway infections.

Age of Child, More than HPV Type, Is Associated with Clinical Course in Recurrent Respiratory Papillomatosis

Background RRP is a devastating disease in which papillomas in the airway cause hoarseness and breathing difficulty. The disease is caused by human papillomavirus (HPV) 6 or 11 and is very variable. Patients undergo multiple surgeries to maintain a patent airway and in order to communicate vocally. Several small studies have been published in which most have noted that HPV 11 is associated with a more aggressive course. Methodology/Principal Findings Papilloma biopsies were taken from patients undergoing surgical treatment of RRP and were subjected to HPV typing. 118 patients with juvenile-onset RRP with at least 1 year of clinical data and infected with a single HPV type were analyzed. HPV 11 was encountered in 40% of the patients. By our definition, most of the patients in the sample (81%) had run an aggressive course. The odds of a patient with HPV 11 running an aggressive course were 3.9 times higher than that of patients with HPV 6 (Fishers exact p = 0.017). However, clinical course was more closely associated with age of the patient (at diagnosis and at the time of the current surgery) than with HPV type. Patients with HPV 11 were diagnosed at a younger age (2.4y) than were those with HPV 6 (3.4y) (p = 0.014). Both by multiple linear regression and by multiple logistic regression HPV type was only weakly associated with metrics of disease course when simultaneously accounting for age. Conclusions/Significance Abstract The course of RRP is variable and a quarter of the variability can be accounted for by the age of the patient. HPV 11 is more closely associated with a younger age at diagnosis than it is associated with an aggressive clinical course. These data suggest that there are factors other than HPV type and age of the patient that determine disease course.

Surgery for Glomus Tumors at the Skull Base

Glomus tumors of the temporal bone frequently involve the skull base. In the present study, 34% of the tumors occurred with cranial nerve palsies and 15% invaded the CNS. The procedure for surgical resection of glomus tumors of the skull base is described. Results of the procedure included successful surgical resection of 80% of the glomus jugulare tumors and of 94% of the glomus tympanicum tumors. Tumor recurrence and persistence occurred only in the patients with CNS invasion.

Trends in the management of pediatric chronic sinusitis: survey of the American Society of Pediatric Otolaryngology.

Background: The management of chronic sinusitis (CS) in children has yet to be fully elucidated. The objective of this study is to assess practice trends within the pediatric otolaryngology community for the management of children with CS.

Nationwide Trends in Pediatric Staphylococcus aureus Head and Neck Infections

OBJECTIVES To evaluate the epidemiologic manifestations of pediatric Staphylococcus aureus head and neck infections nationwide and to identify possible trends in the antibiotic drug susceptibility of S aureus during a 6-year period. DESIGN Retrospective review of microbiologic data from a peer-reviewed national database. SETTING More than 300 hospitals nationwide. PATIENTS All pediatric patients with head and neck infections involving S aureus. MAIN OUTCOME MEASURES Anatomic sites were divided into oropharynx/neck, sinonasal, and otologic infection categories. Demographic and antimicrobial drug susceptibility patterns were reviewed. RESULTS A total of 21,009 pediatric head and neck S aureus infections that occurred between January 2001 and December 31, 2006 were gathered from the database. Predominance was observed in the oropharyngeal/neck category (60.3%). For all sites, the mean patient age was 6.7 years (range, 0-18 years), with a 51.7% male predominance. There was a high occurrence in the North East Central region of the United States. Overall, methicillin-resistant S aureus was seen in 21.6% of all patient isolates (n = 4534), with rates of 11.8%, 12.5%, 18.1%, 27.2%, 25.5%, and 28.1% for 2001 through 2006, respectively. This represents a 16.3% increase in methicillin-resistant S aureus during these 6 years for all pediatric head and neck S aureus infections. CONCLUSIONS There is an alarming nationwide increase in the prevalence of pediatric methicillin-resistant S aureus head and neck infections. Disparities in the treatment of various head and neck infections nationwide may contribute to the regional differences in the prevalence of such infections. Judicious use of antibiotic agents and increased effectiveness in diagnosis and treatment are warranted to reduce further antimicrobial drug resistance in pediatric head and neck infections.

Intracranial complications of sinusitis: what is the role of endoscopic sinus surgery in the acute setting

OBJECTIVE Intracranial complications of sinusitis (ICS) are uncommon in the antibiotic era. The role of neurosurgical drainage of ICS is fairly well established, but the role for acute surgical intervention for the sinus disease is not well defined. We retrospectively reviewed our experience with ICS to see if we could identify the role and effectiveness of endoscopic sinus surgery (ESS) in the acute setting of ICS. METHODS The study used a retrospective review of patients presenting to a tertiary care academic medical center for a 6-year period. RESULTS Twenty-three patients were identified with ICS, including epidural (8), subdural (10), intracerebral abscesses (2), and meningitis (3). Males were more affected than females (7:1). Twenty patients were 21 years old or younger. Twenty-two patients (96%) had radiologic evidence of frontal sinusitis with prefrontal or frontal lobe ICS at presentation. Medical therapy alone was successful in avoiding craniotomy in only 3 of 8 cases. Endoscopic sinus surgery and intravenous antibiotics as initial treatment was successful in avoiding craniotomy in only 1 of 6 patients. Of 23 patients, 18 underwent neurosurgical procedures--9 emergent procedures for abscesses more than 1 cm and 9 delayed procedures for persistent disease despite ICS less than 1 cm at presentation. CONCLUSIONS Intracranial complications of sinusitis usually result from indirect spread of acute frontal sinusitis. The role of ESS in the initial treatment of ICS is not clear. In our series, ESS did not appear to alter the need for neurosurgical intervention, which was ultimately necessary in most patients with ICS, even with lesions less than 1 cm.

Single-Stage Choanal Atresia Repair in the Neonate

OBJECTIVE To evaluate the postoperative results of patients treated with and without the use of stents at the time of initial surgical treatment of choanal atresia (CA). Surgical treatment of CA in the neonatal period is complicated by postoperative stenosis, often necessitating multiple revision surgical procedures. DESIGN Retrospective medical record review. SETTING Tertiary care academic center. PATIENTS The medical records of 9 patients treated for bilateral CA during the neonatal period were reviewed. All patients were treated with an endoscopic approach. Outcomes were compared for patients with and without stent use at the initial operation. MAIN OUTCOME MEASURES Medical records were analyzed for diagnostic modality, clinical symptoms, age at surgery, sex, surgical repair, placement of stents, reoccurrence of atresia, follow-up time, and postoperative outcomes. RESULTS The mean age at initial surgery was 8 days (range, 5-15 days). Four patients had endotracheal tube stents placed at the time of initial surgery for a duration of 4 to 6 weeks. All patients required at least 1 additional surgery (mean, 2.6 procedures), and 3 (75%) had restenosis during infancy. The mean follow-up time for this group was 7.5 months. Five patients did not have stents placed at the time of initial surgery. None of these patients required additional surgical procedures during infancy, and none developed restenosis. The follow-up time for this group was 2.5 months. CONCLUSIONS This study suggests that the placement of stents for bilateral CA repair during the neonatal period results in a high rate of restenosis as well as the need for multiple subsequent procedures during infancy. The use of an endoscopic approach without stent placement appears to result in superior healing without the need for revision surgery.

Clinical manifestations of sinonasal pathology during pregnancy.

OBJECTIVE Pregnancy may confer a number of conditions related to the head and neck. The objective of this study was to evaluate the clinical manifestations of sinonasal pathology that occur during pregnancy. METHODS Thirty-three pregnant patients were evaluated for the occurrence of rhinorrhea, congestion, epistaxis, or acute sinusitis during the first trimester of pregnancy, controlling with 28 women of child-bearing age. A visual analogue scale was used to grade the severity of each symptom. Statistical analysis was carried out to assess for significant differences in the prevalence and severity of symptomatology between cases and controls. RESULTS Compared to the control group, there was no statistically significant difference in the prevalence of congestion, epistaxis, rhinorrhea, or acute sinusitis. There was no statistically significant difference in the severity of any presenting symptom between pregnant and control group patients. CONCLUSION Pregnancy is not associated with an increased prevalence or severity of nasal symptomatology during early pregnancy. The influence of hormonal changes on nasal physiology during pregnancy is discussed with a view toward safe management.
