Computer-assisted anatomical evaluation of the nasal sinuses in 1-2 years old children / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To analyze the anatomical and developmental characteristics of nasal sinuses in 1-2 years old children; and provide potential evidence for the diagnosis and treatment of sinusitis in 1-2 years old children.@*METHOD@#Coronal CT scans of 60 cases (1-2 years old children) were studied with the imaging station. Reference datas were identified on these images using imaging station. The gasification conditions of the sinuses were identified and measured.@*RESULT@#100% of the frontal sinuses were not developed, while 100% of the maxillary sinuses were developed. The mean of the transverse and vertical diameters for the left side of the maxillary sinuse was (13.32 ± 2.88) mm and (13.55 ± 2.43) mm, respectively. While those for the right side were (13.63 ± 2.75) mm and (13.59 ± 2.13) mm, respectively. The anterior and posterior ethmoid sinuses were 100% developed. The mean transverse and vertical diameters for the left side of the anterior ethmoid sinus were (3.94 ± 0.86) mm and (11.92 ± 1.67) mm, respectively. While those mean for its right side were (3.88 ± 0.88) mm and (12.18 ± 1.86) mm, respectively. The mean transverse and vertical diameters for the left side of the posterior ethmoid sinus were (6.02 ± 1.07) mm and (10.51 ± 1.43) mm, respectively. While those for the right side were (5.91 ± 1.20) mm and (10.51 ± 1.55) mm, respectively. 88.3% (106 sides) of the sphenoid sinuses were developed, while 11.7% (14 sides) were not developed. The mean transverse and vertical diameters for the left side of the sphenoid sinus were (5.18 ± 2.15) mm and (5.78 ± 1.86) mm, respectively. While those for the right side were (4.91 ± 2.24) mm and (5.89 ± 2.03) mm, respectively.@*CONCLUSION@#The nasal sinuses in 1-2 years old children have been already developed. The development of the maxillary and ethmoid sinuses was clear and definite. The pneumatization of the sphenoid sinus was defined in many babies; however, the pneumatization of the frontal sinus was not defined in all babies. Acute rhinosinusitis in 1-2 years old children is not uncommon. Therefore, definite diagnosis and positive treatment of such cases are essential for avoidance of serious complications.

Bronchial foreign body of a 8-month infant: a case report / 临床耳鼻咽喉头颈外科杂志

A foreign body was found in left bronchi of a 8-month infant. A fish bone of 26 mm long was pulled out with bronchoscopy under general anesthesia. This kind of surgery done in infant is more challenging than that done in child.

Computer-assisted anatomical evaluation of the nasal sinuses in infants / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To analyze the anatomical and developmental characteristics of nasal sinuses in infants; and provide potential evidence for the diagnosis and treatment of sinusitis in infants.@*METHOD@#Coronal CT scans for 36 infants (72 sides) were studied with the imaging station. Reference data were identified on these images using imaging station. The gasification conditions of the sinuses were identified and measured.@*RESULT@#100% of the frontal sinuses were absent, while 100% of the maxillary sinuses were developed. The mean of the transverse and vertical diameters for the left side of the maxillary sinuses was (8.69 +/- 3.75) mm and (9.37 +/- 2.36) mm, respectively. While those for the right side were (8.95 +/- 2.79) mm and (9.06 +/- 2.66) mm, respectively. All of the anterior and posterior ethmoid sinuses were developed. The mean transverse and vertical diameters for the left side of the anterior ethmoid sinus were (3.63 +/- 1.17) mm and (8.21 +/- 2.72) mm, respectively. While those mean for its right side were (3.48 +/- 1.32) and (8.28 +/- 2.62) mm, respectively. The mean transverse and vertical diameters for the left side of the posterior ethmoid sinus were (4.09 +/- 1.13) mm and (6.61 +/- 1.36) mm, respectively. While those for the right side were (4.01 +/- 1.28) mm and (6.63 +/- 1.97) mm, respectively. 30.6% (22 sides) of the sphenoid sinuses were developed, while 69.4% (50 sides) were not.@*CONCLUSION@#The nasal sinuses in infants have already developed. The development of the maxillary and ethmoid sinuses was clear and definite. The pneumatization of the sphenoid sinus was defined in some babies, however, the pneumatization of the frontal sinus was not defined in all babies.

Low-frequency tympanometry in normal neonates / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To find the characteristic of tympanogram results obtained from normative neonates 2 - 7 days about low frequency (226 Hz) probe tone, and to determine the normative values for tympanometric variables.@*METHOD@#Transient evoked otoacoustic emission (TEOAE) screening were performed by using AccuScreen Pro instrument for 135 neonates. Among them, 105 neonates passed the TEOAE screening in both ears. The 226 Hz probe tone tympanograms and their normative values were obtained from them using GSI-33 middle ear analyzer.@*RESULT@#The 226 Hz tympanometric data for the 105 neonates (210 ears) passed the TEOAE screening in both ears showed a double-peaked tympanogram in 202 ears (96.19%), a single-peaked tympanogram in 8 ears (3.81%). For double-peaked tympanogram in 202 ears, the tympanometric normative values was below: the first peak admittance is (0.91 +/- 0.18)mmho, Tpp is about (18.02 +/- 12.26)daPa; the second peak admittance is (1.05 +/- 0.23)mmho, Tpp is about (-35.05 +/- 16.80) daPa; the admittance of notch between the two peaks is (0.74 +/- 2.57)mmho, its pressure is about (0.37 +/- 7.61) daPa. Vec is about (0.50 +/- 0.08)ml.@*CONCLUSION@#The 226 Hz tympanograms obtained from this cohort may serve as a guide for evaluating middle ear function in neonates.

The character of pediatric chronic sinusitis with chronic cough / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To evaluate clinical and imaging character of chronic rhinosinusitis in the children with chronic cough and to discuss the treatment of them.@*METHOD@#Fifty-three children with chronic cough were examined by otolaryngologists and evaluated by computed tomography (CT) scan. Some of them were also evaluated by nasal endoscope. There was not any finding of lung in chest X-ray in Adhese children and children with immunodeficiency were ruled out from the study. The children with chronic sinusitis were treated according to general protocols for 6 to 8 weeks, among them those with adenoid vegetation accepted adenoidectomy.@*RESULT@#Forty-three cases of 53 children with chronic cough, aged from 2 years and 10 months to 13 years old (average 7 years old), were proved with sinusitis by CT. The main symptom of them was chronic cough. Thirty-five cases of these 43 children were with purulence, among them, 8 cases with mucoid in middle meatus, 28 cases with folliculosis in posterior oropharynx, and 6 children with adenoid vegetation. Clinical stage of 19 cases of 53 children were belonged to I type 3 stage, 19 cases belonged to I type 2 stage, 5 cases belonged to I type 1 stage. The maxillary sinus was most frequently involved, followed by the ethmoid sinus, the frontal sinus, the sphenoid sinus. All of the 43 children with sinusitis accepted treatment for 6 to 8 weeks. After treatment, 81.4% of patients were fully recovered, 18.6% significantly improved, 4 with adenoidectomy and 2 with tympanostomy tubes.@*CONCLUSION@#The relationship between chronic sinusitis and chronic cough in children was closer than that in adults. It is very easy to make misdiagnosis because of other symptoms.
