Sinusitis. Diagnostic methods.

Sinusitis, which primarily involves the anterior ethmoid air cells, can spread to the larger sinus cavities to cause acute and chronic secondary infection. Endoscopic and computed tomographic techniques enable earlier diagnosis and treatment of sinusitis and permanent cure. Primary care physicians should try to identify the disease before it reaches a stage where endoscopic control becomes difficult. Ultrasonography is now used in Europe to diagnose sinusitis and initiate treatment.

Humans

Diagnosis of frontal sinusitis: one-dimensional ultrasonography versus radiography.

In a series of 407 patients suffering from acute frontal sinusitis, 159 sinuses of 134 patients were trephined. Initial radiography of the operated sinuses pointed out a slight tendency to overdiagnosis; 19 (12 per cent) of the 157 sinuses with positive radiographic signs did not yield secretion. Radiography missed only two true cases of fluid retention. Accuracy of diagnosis by radiography was 87 per cent. Initial ultrasonography gave a sign of retained secretion in 127 cases, of which 122 (96 per cent) were true positive. However, 18 (13 per cent) tracings of the 140 sinuses with secretion gave wrong negative findings. Accuracy of diagnosis by ultrasonography was 86 per cent. It seems evident, that ultrasonography measures better retained secretion (excluding very small amounts) and radiography shows better mucosal swellings.

Adult

The diagnosis and follow-up of pediatric sinusitis: Water's view radiography versus ultrasonography.

Water's view plain film radiography was compared with ultrasonography in the diagnosis and follow-up of acute maxillary sinusitis in 85 children (170 sinuses). At the first visit, the concordance of the two modalities was 91%, but 20 days later, when the symptoms and signs had disappeared, it was only 76%. At the latter date, the concordance between radiography and clinical findings was 71% and between sonography and clinical findings, 93%. The two modalities studied appear to be equally useful in the initial diagnosis of acute maxillary sinusitis. The loss of back-wall echo correlates well with symptomatic improvement of acute sinusitis. Sonography is also nonionizing and inexpensive, and the examination is simple to repeat.

Child

Diagnosis and follow-up of ultrasonographical sinus changes in children.

Retained secretion within the maxillary sinus was diagnosed by ultrasonography in 86 (19%) of 452 children (4-10 years) who entered Turku University ENT-clinic for adenoidectomy or adenotonsillectomy. Occipitomental radiographs showed signs of sinusitis in 168 (37%) of the children. All 86 children with secretion in one or both maxillary sinuses were operated on and treated with amoxicillin and a nasal decongestant. Fifty children (72 sinuses) were treated with antral lavage and 36 children (49 sinuses) were treated conservatively. After 10 days ultrasonography revealed no secretion in 86% of the irrigated sinuses and in 74% of the sinuses treated without irrigation. After 30 days all the irrigated sinuses were healed but in 5 (10%) of the sinuses treated without irrigation ultrasonography still revealed retained secretion. The difference was statistically significant. The disappearance of the radiographic sinus changes was considerably slower. As a non-ionizing method ultrasonography was found to be especially practical in the follow-up of treatment results. It seems that the disappearance of ultrasonic signs of sinusitis correlates better with the clinical resolving of sinusitis in childhood than the disappearance of radiographic signs of sinusitis.

Amoxicillin

Diagnosis of subacute maxillary sinusitis in children.

The prevalence of subacute, occult maxillary sinusitis in children undergoing adenoidectomy, adenotonsillectomy or tympanostomy was 27 per cent as confirmed by antral puncture. A-mode ultrasound examination and radiographic examination with the occipito-mental projection were used as preoperative screening tests for the detection of maxillary sinus discharge. 135 children aged 4--10 years were examined. An abnormal radiographic finding was found in 40 per cent of children. When punctured these sinuses yielded discharge in 62 per cent of cases. A normal radiographic finding proved to be reliable (98 per cent). The total agreement between puncture and radiographic finding was 73 per cent. The total agreement between puncture and A-mode ultrasound finding was 94 per cent. The A-scan was positive in 88 per cent of the sinuses with discharge. A-mode ultrasonic examination proved to be a simple, non-ionizing reliable means of monitoring retained secretion within maxillary sinuses of children.

Adenoidectomy

[Ultrasound testing in the diagnosis and management of maxillary sinusitis in children (author's transl)].

A- and B-mode ultrasound testing was used in conjunction with X-ray studies as screening tests for the detection of maxillary sinusitis in 280 children (aged 4-10 years) about to undergo adenoidectomy, and/or tonsillectomy and/or tympanostomy. X-rays were abnormal in 114 (41%) children, while sinus disease with the retention of discharge was diagnosed by ultrasound in 63 (23%) children. These latter children were then treated for ten days with amoxicillin and decongestant (Rinexin). At time of initial surgery, 63 maxillary sinuses (in 43 of the children) were punctured and irrigated. Another group (consisting of 27 sinuses in 20 children) was treated without antral puncture. All children were reexamined after 10, 20 and 30 days with ultrasound and radiography. After 10 days, there was no discharge found in 86% of the sinuses treated by antral puncture and in 85% of the control sinuses. After one month, all sinuses which had been irrigated were found to be free of disease, while three (11%) of the control group contained discharge. However, the healing process in all patients seemed to be slower, as evidenced by sequential sinus X-rays.--We believe that ultrasonic evaluation of the maxillary sinuses is a simple, rapid and reliable method for the diagnosis and followup of maxillary sinusitis in children. With this technique, it is possible to follow the disappearance of residual sinus discharge as well as diagnose cases which need active treatment.
