Paranasal sinusitis associated with nasotracheal and orotracheal long-term intubation.

The impact of nasotracheal and orotracheal long-term intubation on the development of sinusitis paranasalis was investigated in a prospective study. Daily A-scan ultrasound examinations of the maxillary sinuses were performed on 44 intensive care unit patients (20 nasally, 24 orally intubated) who required prolonged intubation (greater than 24 hours). At the end of the investigation period 19 (95%) of 20 nasotracheally and 15 (63%) of 24 orotracheally intubated patients showed pathologic antral sinus findings. In nasally intubated patients the incidence of bilateral sinusitis was significantly higher and its onset sooner. Pathologic organisms were found in the sinus aspirates in seven of 13 nasotracheally intubated patients, but only in two of nine patients with an oral tube. Thus, the nasotracheal tube can be seen as an adding factor in the development of sinusitis paranasalis.     

Sinusitis in the nasotracheally intubated patient

Maxillary sinusitis as a complication of nasotracheal intubation has long been recognized as difficult to diagnose and equally difficult to treat. To better define this problem from a diagnostic and therapeutic standpoint, we studied patients admitted to the surgical intensive care unit at the University of Texas Health Science Center at Houston-Hermann Hospital over a six-month period. During this time, we identified 19 cases of maxillary sinusitis. Diagnostic criteria included fever, leukocytosis, purulent rhinorrhea, and maxillary sinus opacification or air fluid level noted on sinus roentgenograms. Patients who met these criteria underwent maxillary sinus aspiration. Sixteen patients were receiving antibiotic therapy when sinusitis was diagnosed. All patients had their endotracheal tubes replaced orally, had diseased maxillary antra lavaged, and underwent appropriate antibiotic therapy guided by culture and sensitivity studies. Four of 19 patients required more than one sinus lavage, but all patients had their sinus disease resolve. These data suggest an aggressive approach to diagnosing sinusitis in the nasotracheally intubated patient is needed. A maxillary sinus aspiration and lavage should be an integral part of the diagnosis and treatment of these patients.     

The relationship between anatomic variations of paranasal sinuses and chronic sinusitis in children

CONCLUSIONS: Anatomical variations in the nose and paranasal sinuses are common in children. Due to the absence of a definitive relationship between anatomical variations and sinus disease, local, systemic or environmental factors appear to be more significant in pediatric sinusitis than the anatomic variations. OBJECTIVE: Chronic sinusitis is increasing in the pediatric population. Following the initial reports of functional endoscopic sinus surgery (FESS) for children, the majority of patients undergoing this procedure have experienced improved quality of life. Thus, we need to know the precise anatomy and anatomical variations of the nose, as well as the relationship between such anatomy and chronic sinusitis. PATIENTS AND METHODS: To determine the extent and distribution of disease, as well as associated anatomic abnormalities, computed tomography (CT) scans were performed on 113 children with persistent symptoms of sinusitis after failure of medical therapies. RESULTS: The maxillary sinus was the most commonly involved sinus, followed by the ethmoid, sphenoid, and frontal sinuses. There was no relationship between age and severity of sinusitis. Agger nasi cell was the most common anatomical variation, followed by septal deviation, Haller cell, concha bullosa, paradoxical middle turbinate, and Onodi cell. The prevalence of septal deviation increased with age. There was no significant relationship between the sinusitis and anatomic variations.

Maxillary Sinus Development in Patients With Cleft Palates as Compared to Those With Normal Palates

Maxillary sinusitis appears to be more prevalent in the cleft palate population than in the normal population. The increase in sinusitis may be due to the fact that the maxillary sinus develops differently embryonically in cleft palate patients than in those patients with normal palates. A double blind study was done by measuring the maxillary sinus cephalometric x-rays in cleft palate patients and then comparing them to patients with normally developed palates. The groups studied were 3 months to 20 years of age. It was concluded that in each of these groups there was no significant difference in size, shape, or rate of development of the maxillary sinus in cleft palate patients compared to the normal population. It is probable that the increased incidence of maxillary sinusitis in cleft palate patients is due mainly to the open palate with constant contamination of the nasal mucosa by food pushed into the nares and sinus ostia, resulting in maxillary sinusitis.     

The correlation between bacteriological findings in the nose and maxillary sinus in acute maxillary sinusitis

Nasal and sinus bacteriology have been investigated in healthy controls and in patients with acute maxillary sinusitis. Comparatively few healthy noses were sterile, and in controls the nasal bacterial flora commonly consisted mainly of staphylococci and diphtheroid rods. Nasal specimens from patients with sinusitis showed most common findings to be “no growth,” pneumococci, Haemophilus influenzae and staphylococci in that order. In aspirated sinus secretions there was a predominance of pneumococci, “no growth” and Haemophilus influenzae. Other bacteria were uncommon. Staphylococci were shown conclusively to be nasal contaminants. The same organisms were found in the nasal and sinus secretions of patients with sinusitis in only 64 percent, thus indicating that nasal samples are of low predictive value in reflecting sinus flora. It can be argued that in the individual patient with sinusitis it is more reliable to base therapy on the results of previous bacteriological investigations than on the individual bacteral findings in the nose.     

Isolated inflammatory sphenoid sinus disease in children

Isolated inflammatory disease of the sphenoid sinus is very uncommon in the pediatric population. A 10-year review of all patients at our institution 16 years of age or younger with inflammatory sphenoid sinus disease found 8 patients with isolated sphenoid sinusitis and 3 with sphenoid mucoceles. The most common symptoms were headache and visual disturbance. Five patients with uncomplicated sinusitis were successfully managed medically, while 3 with either complicated sinusitis or sinusitis not responding to antibiotics were treated by endoscopic sphenoidotomy. All patients with a mucocele were treated surgically. Isolated inflammatory sphenoid sinusitis should be considered in children age 7 years or older who present with headache that does not respond to simple analgesia. Delayed diagnosis and advanced disease may lead to life-threatening complications.     

Screening sinus CT scans in pediatric bone marrow transplant patients

OBJECTIVE: To determine how sinus disease noted on pre-bone marrow transplant (BMT) screening sinus computed tomography (CT) scans relates to subsequent development of clinical and/or radiographic sinusitis and correlates with overall prognosis. METHODS: A retrospective review of medical records, CT scans, and BMT database statistics was performed on all pediatric BMT recipients from January 1992 through December 1997. Fifty-four pre-BMT CT scans were performed on 51 children, aged from 2 months to 17 years. Sinus disease was staged according to criteria established by Lund and Kennedy [V.J. Lund, D.W. Kennedy, Ann. Otol. Rhinol. Laryngol. S167 (1995) 17-21.]. RESULTS: The average age of BMT recipients was 6.8 years. Most common oncologic diagnoses included acute myelogenous leukemia (37%), acute lymphoblastic leukemia (17%), and stage IV neuroblastoma (13%). Screening sinus CT scans were routinely performed 1-3 months prior to BMT. On pre-BMT CT scans 48% of the patients had no evidence of sinus disease, 25.9% mild disease, 9.3% moderate disease, and 16.7% severe disease. Two-thirds (66.7%) of patients with severe sinus disease on pre-BMT CT scans experienced clinical sinusitis post-BMT. In contrast, sinus symptoms were much less common (21.4%) in those with mild disease on CT scan. Overall, 39.3% of patients with sinus abnormalities on pre-BMT CT scans had clinical sinusitis during their post-BMT course, compared to 23.1% of those with normal CT scans pre-BMT. In addition, those patients demonstrating sinus disease on their pre-BMT CT scan were more likely to have radiographic sinusitis post-BMT (25.0%) than those with no disease (7.7%). Seventy-eight percent of those with severe sinusitis had died by 2-year follow up, compared to 69.2% of patients with normal CT scans pre-BMT. CONCLUSIONS: Severity of radiographic sinus disease on pre-BMT CT scans was noted to correlate with clinical and radiographic sinusitis later in the post-BMT course, and was associated with a trend toward decreased survival. Pre-BMT CT scans may be useful in determining which children need early and more aggressive intervention for clinical sinusitis post-BMT.

Sinusitis complicated by meningitis: current management

OBJECTIVES: Meningitis is the most common intracranial complication of sinusitis. We review the incidence, current management, outcomes, and complications of this serious infection. Our study also examines the evolving roles of endoscopic sinus surgery and other new therapeutic and diagnostic modalities in our armamentarium. STUDY DESIGN: A retrospective chart review was performed at a tertiary academic medical center of all patients diagnosed with sinusitis with complications between January 1985 and December 1999. METHODS: The patients were divided into two main groups: intracranial versus orbital complications. Meningitis was the most common intracranial complication. Data on patients with sinusitis and meningitis were collected and analyzed. RESULTS: Intracranial complications were present in 39 of 82 patients whereas orbital complications were noted in 43 patients. Twenty-one of the 39 intracranial complications were meningitis. The most common computed tomography finding in adults (54%) was sphenoid sinusitis. All patients with AIDS (6 of 21) had unique cryptococcus meningitis. In patients without AIDS, the most common organism was Streptococcus pneumoniae (10 of 21). The most common sequela was seizure disorder (4 of 21). Endoscopic sinus surgery was performed on 7 of 21 patients. One patient with AIDS who had sinusitis and meningitis died. CONCLUSIONS: Meningitis as a complication of sinusitis may still pose a serious threat. Although outcomes are encouraging, sequelae such as seizure disorders and hearing loss are common complications. The introduction of high-resolution computed tomography scans and magnetic resonance imaging and the availability of wide-spectrum antibiotics have improved our management significantly.

Paranasal sinus computed tomographic findings of children with chronic cough

Objective: Chronic cough is a frequent problem in the practice of clinical pediatrics, and sinusitis is a common etiologic factor. In this study, our aim was to determine the prevalence of sinus abnormalities in pediatric patients presenting with chronic cough. Methods: Forty-two patients, ranging from 3 to 16 years of age from both sexes completed the study. Paranasal sinuses were examined by coronal paranasal sinus limited computed tomographic scan. The CT scan findings were categorized as no disease, minimal, moderate and severe sinusitis. Results: The most frequent symptoms after cough were rhinorrhea, sniffling, and halitosis. We found sinus abnormalities in 66.6% and no abnormality in 33.3% of the children. Age and sex were not important factors in sinus disease. There was no correlation between sinus findings and any of symptoms. The most common anatomical abnormalities were concha bullosa, paradoxical middle turbinate, Haller's cells, and deviated nasal septum. These abnormalities were not correlated with sinus disease. Conclusion: Paranasal sinus abnormalities are common among pediatric patients with chronic cough and imaging studies of the sinuses should be considered in these children.     

Aerobic and anaerobic bacteriology of concurrent chronic otitis media with effusion and chronic sinusitis in children

OBJECTIVE: To correlate the aerobic and anaerobic microbiologic findings of concurrent chronic otitis media with effusion and chronic maxillary sinusitis. METHODS: Cultures were obtained from 32 children with concurrent chronic otitis media with effusion and maxillary sinusitis who underwent tympanostomy tube placement. RESULTS: A total of 42 isolates, 24 aerobic and 18 anaerobic, were recovered from 30 patients; 27 were isolated from both sites, 4 from the ear only, and 11 from the sinus only. The most common isolates were Haemophilus influenzae (9 isolates), Streptococcus pneumoniae (n = 7), Prevotella species (n = 8), and Peptostreptococcus species (n = 6). Microbiological concordance between the ear and sinus was found in 22 (69%) of culture-positive patients. CONCLUSION: The concordance in recovery of organisms in more than two thirds of the patients illustrates the common bacterial etiology between chronic otitis media with effusion and chronic sinusitis in children.

Acute bacterial sinusitis in adults: management in the primary care setting

Sinus disease is inherently associated with viral upper respiratory tract infections and occurs in 90% of individuals with the common cold. Acute bacterial sinusitis occurs in 0.5 to 2% of these individuals. Although the diagnosis of acute bacterial sinusitis is usually based on physical findings, no one sign or symptom is either sensitive or specific for sinusitis. The predictive power can be significantly improved when all signs and symptoms are combined into a clinical impression. Imaging studies have not been shown to be cost effective in the initial assessment and treatment of patients in the primary care setting. Simple plain films may be indicated to resolve the diagnosis in patients with an equivocal history or to follow patients admitted to hospital with severe sinus disease. The initial management of acute sinusitis should be directed toward the relief of symptoms with a 7-day course of decongestants and mucoevacuents. For patients who fail to improve with symptomatic treatment, a 10-day course of amoxicillin is recommended. Second line antibiotics should be initiated if improvement is not seen within 72 to 96 hours.

目的 探讨额下入路颅脑手术后并发额窦炎的原因、临床表现和治疗原则.方法额下入路颅脑手术后出现额窦炎的患者共33例,其中7例合并额窦脓肿,4例前额皮肤破溃瘘道.传统鼻外进路额窦手术23例,术后放置鼻额引流扩张管3个月以上;鼻内镜下额窦手术9例,鼻内镜和鼻外联合进路额窦手术1例,引流扩张管在出院前或出院后1个月内拔除.两种术式均需彻底清除额窦内骨蜡异物和炎性肉芽组织.复习颅脑手术病历结合鼻窦CT影像和额窦手术所见探讨并发额窦炎的原因.结果 33例患者均有颅脑术中开放额窦,将额窦黏膜下推或刮除,并以骨蜡填塞额窦的记录,其中5例有发生额窦炎后重新刮除额窦内黏膜并再次以骨蜡彻底封闭额窦的病史.所有患者均在拔除硅胶鼻额引流扩张管后随访半年以上.除2例鼻外进路手术的患者出院后1个月内鼻额引流扩张管脱落,经2次手术外,余31例均为1次手术.33例中30例治愈,3例好转.两种手术方式治疗效果相同.无脑脊液鼻漏等并发症.结论 额下入路颅脑术后并发额窦炎与颅脑术中额窦处理不当、额窦内骨蜡异物存留有关,此类额窦炎易形成额窦脓肿、瘘道等严重临床表现,治疗原则以清除额窦内骨蜡异物、清除炎性肉芽组织、开放额隐窝引流为主.传统鼻外进路额窦外科和鼻内镜额窦外科都可以达到治疗目的,但鼻内镜额窦外科具有微创、不必长期佩戴扩张管等优点.     

Computed tomography evidence of dental restoration as aetiological factor for maxillary sinusitis

Maxillary sinusitis due to dental causes is usually secondary to periodontal disease or periapical infection and is commonly associated with mucosal thickening of the floor of the maxillary antrum. Computed tomography (CT) is currently the modality of choice for evaluating the extent of disease and any predisposing factors in patients with symptoms of chronic maxillary sinusitis, but it is unable to diagnose dental disease reliably. The presence of restorative dentistry is, however, easily seen at CT and is associated with both periapical and periodontal disease. We aimed to determine whether its presence at CT may predispose to maxillary sinusitis, and in particular to focal mucosal thickening of the sinus floor characteristic of dental origin. Three hundred and thirty maxillary sinus CT images in 165 patients were reviewed for the presence of restorative dentistry in the adjacent teeth, focal maxillary sinus floor mucosal thickening, any maxillary sinus disease (including complete opacification, air fluid levels, diffuse mucosal thickening, focal mucosal thickening) and evidence of a rhinogenic aetiology (osteomeatal complex pathology, mucosal thickening in other sinuses). One hundred and ninety two sinuses adjacent to restorative dentistry and 178 sinuses not adjacent to restorative dentistry were analysed. Focal floor thickening both with, and without, evidence of a rhinogenic aetiology, was significantly more common adjacent to restorative dentistry. Maxillary sinus disease overall was no more common adjacent to restorative dentistry. This work demonstrated that the presence of restorative dentistry predisposes to focal mucosal thickening in the floor of the maxillary sinus and its presence should prompt clinical and radiographical assessment to exclude dental disease as a source of chronic maxillary sinusitis.     

Clinical impact of ectopic teeth in the maxillary sinus

OBJECTIVE: To evaluate the clinical features, aetiologic factors, challenging properties (such as radio opacity in Water's view in a patient with no sinusitis), signs and symptoms of the ectopic teeth in the maxillary sinus. STUDY DESIGN: Clinical symptoms and radiographic findings of 14 patients with ectopic teeth in the maxillary sinus were evaluated. Computed tomography (CT) and conventional radiographic images of maxillary sinus and clinical findings were compared with each other with regard to the final diagnosis. RESULTS: Water's view is inadequate to diagnose ectopic tooth in the maxillary sinus in some cases. Panoramic radiographs may be preferred before CT to evaluate the ectopic tooth in the maxillary sinus as structure of a tooth can be clearly detected on panoramic radiographs. Crowding was the most common aetiologic factor among the 14 cases. CONCLUSION AND SIGNIFICANCE: The patients with ectopic tooth in the maxillary sinus should be evaluated thoroughly by complete otorhinolaryngologic, intraoral examinations and proper diagnostic imaging procedures in order to avoid misdiagnosis of maxillary sinusitis. As the opacity of the maxillary sinus in Water's view due to ectopic tooth can be misinterpreted as maxillary sinusitis, patients who have sinusitis-like complaints and opacity of maxillary sinus in Water's view who are resistant to medical treatment should be evaluated with respect to the presence of ectopic tooth.
