Location of tympanic segment and mastoid segment of facial nerve and prevention of prosopoplegia in operations / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To study the location of facial nerve and prevent facial nerve injury in middle ear surgery according to dissection of temporal bone and experience of middle ear surgery.@*METHOD@#Thirty sides of temporal bones were exposed tympanic and mastoid segment of facial nerve with facial nerve decompression. The course of facial nerve was located by the markers of middle ear.@*RESULT@#Tympanic segment of facial nerve passed between horizontal semicircular canal and stapes,then superior and anterior to the cochleariform process. Mastoid segment of facial nerve located in posterior wall of tympanic cavity. The mastoid segment of facial nerve travelled below the level of horizontal semicircular canal and annulus membrane tympani, and the extension line of its posterior margin and posterior-one-third of horizontal semicircular canal intersected to form an included angle (117.04 +/- 2.42) degrees. External genu of facial nerve located anterior and inferior to the horizontal semicircular canal. The shortest distance was (1.97 +/- 0.53) mm between middle point of horizontal semicircular canal and facial nerve, (1.03 +/- 0.29) mm between incus short process and facial nerve, (0.93 +/- 0.25) mm between cochleariform process and facial nerve, (1.18 +/- 0.42) mm between head of stapes and facial nerve, (3.08 +/- 0.28) mm between tympani sulcus and facial nerve at the vestibule window level, and (2.13 +/- 0.34) mm between tympani sulcus and facial nerve at round window level, respectively.@*CONCLUSION@#Horizontal semicircular canal carina, incus short process, stapes, annulus membrane tympani and cochleariform process are ideal landmarks of tympanic and mastoid segment of facial nerve, which are helpful in middle ear surgery.

Destruction of ossicular chain and its impact on hearing of patients with chronic suppurative otitis media / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To study the characteristic of destructive ossicular chain and to evaluate integrity of ossicular chain and its impact on bone-conduction hearing of patients with chronic suppurative otitis media.@*METHOD@#The destruction of ossicular chain with microscopy during operation and the preoperative pure tone audiometry were observed in 148 patients (176 ears) with chronic suppurative otitis media.@*RESULT@#Destruction of ossicular chain was often observed in patients with chronic otitis media of cholesteatoma type, granuloma type and pars flaccid perforation of tympanic membrane. It initiated destructed malleo-incudal and incudostapedial joint for pars flaccid and pars tensa perforation of tympanic membrane respectively. Normal ossicular chain structure was observed in 52 ears. Destruction of ossicular chain was observed in 124 ears. Difference were significant for speech frequency air-conduction threshold and air-bone gap between group of normal ossicular chain and group of abnormal ossicular chain (P< 0.01). There was no difference for bone-conduction threshold between the above two groups.@*CONCLUSION@#Destruction of ossicular chain was often observed in patients with chronic otitis media of cholesteatoma type and granuloma type. The ossicular chain was normal in the patients who were both less than 40 dB in speech frequency air-conduction threshold and 30 dB of air-bone gap. The ossicular chain was destructed in the patients who were both over 55 dB in air-conduction threshold and 40 dB of air-bone gap. High frequency hearing loss was observed in patients with chronic suppurative otitis media.

Association between infant breastfeeding and temperamental characteristics development in children aged 4-5 years / 中国组织工程研究

BACKGROUND: Temperament plays an important role in psychological development of children. Generally speaking, temperament is genetically determined, but it is also influenced by some other factors. The influential factors studies of temperament are important to promote psychological development and reduce behavior problems of children.OBJECTIVE: To explore the correlation between breastfeeding and temperamental characteristics in children aged 4-5 years old.DESIGN: Random cluster sampling.SETTING: Affiliated Hospital of Medical College, Qingdao University, Zibo Central Hospital, and Research Institute of Pediatrics, Medical College of Qingdao University.PARTICIPANTS: 737 children (399 males, 338 females) aged 4-5 years old from 8 kindergartens of 4 districts in Zibo were selected from March to June 2005. All the subjects and their parents were informed about the experimental goal.METHODS: With stratified random cluster sampling, 737 children were investigated by NYLS 3-7 years old children temperament questionnaire and self-made inventory questionnaire. The association of 9 dimensions including adaptability, rhythmicity (regularity), activity level, persistence, quality of mood, approach and withdrawal, intension of reaction, distractibility and threshold of responsiveness with feeding type in the first 4 months after birth and duration of breastfeeding was analyzed; the multiple gradual regressive analysis was carried out with each dimension of temperament as the dependent variable and feeding type in the first 4 months after birth and duration of breastfeeding etc. as the independent variables.MAIN OUTCOME MEASURES: Temperamental dimension, feeding categories in the fist 4 months, and breastfeeding duration.RESULTS: All 737 children were involved in the result analysis. Correlation analysis indicated that temperamental adaptability was positively related with formula milk mainly in the first 4 months after birth (r =0.084, P =0.030);Rhythmicity and distractibility were negatively related with formula milk only (r =-0.087, -0.075, P =0.022, 0.047);Activity level were positively related with breast milk only and negatively with both breast milk and formula milk equally (r =0.084, -0.077, P =0.030, 0.045); Approach and withdrawal was negatively related with breast milk mainly (r =-0.097, P =0.012). Rhythmicity, quality of mood and activity level were negatively related with breastfeeding for 4-6 months (r =-0.082, -0.102, -0.153, P =0.036, 0.009, 0.001); Quality of mood and activity level were positively related with the duration of breastfeeding more than 9 months (r =0.089, 0.088, P =0.024,0.025). After rectifying the family structure, and educational level of parents, the influencing factor of adaptability was formula mainly; intensity of reaction was breastfeeding duration for 4-6 months and breast milk mainly;rhythmicity was breastfeeding duration for 7-9 months and formula only; activity level was both breast milk and formula milk equally and breastfeeding duration for 7-9 months; quality of mood was formula only and duration of breastfeeding for 7-9 months; approach-withdrawal was breast milk mainly and both breast milk and formula milk equally; distractibility was formula milk mainly.CONCLUSION: Temperamental development of children aged 4-5 years old is related to feeding type in the first 4 months after birth and duration of breastfeeding; therefore, it is essential to pay attention to breastfeeding during temperamental cultivation and intervention.

Effect of family members' intervention on rehabilitation of motor dysfunction after acute cerebral infarction / 中国康复理论与实践

@# ObjectiveTo explore the effect of the intervention by the family members on the rehabilitation of dysfunction of the patients with hemiplegia after acute cerebral infarction.MethodsSixty patients of hemiplegia caused by acute cerebral infarction were randomly divided into two groups, observing group and control group(30 patients for eaeh group).Patients in the observing group received family members' intervention in addition to the regular drug and rehabilitation treatment,which was used in control group only.The change of scores of Fugl-Meyer Assessment(FMA) and Modified Barthel Index(MBI) before and after treatment was evaluated respectively.ResultsThe scores of FMA and MBI in both groups rose very significantly eight weeks after treatment(P<0.001). But the scores of the obersevertion group were higher than that of the control group(P<0.05).ConclusionProper intervention by the family members plays an important role in enhancing the rehabilitation of acute cerebral infarction dysfunction and developing the patiennts' ability to take care of themselves in daily life.
