OBJECTIVE: To heighten the awareness of the facial nerve tumors. METHOD: The clinical data of twenty-three patients complaining of facial paralysis who were diagnosed postoperatively as facial nerve tumors were analyzed. The hearing assessment of all patients was based on pure tone audiometry at the frequency of 0. 5, 1, 2, 4 kHz. Temporal bone high resolution CT scan and temporal bone MRI with gadolinium enhancement were conducted on all patients. Facial nerve function was assessed with the House-Brackmann (HB) grading system. Facial electroneurography (ENoG) was conducted on 20 patients to quantify the degree of nerve degeneration preoperatively. The pathological types of tumor were determined by postoperative pathological reports. RESULT: Nineteen out of 23 cases presented hearing loss (82.6%), 10 cases suffered from tinnitus (43.5%), otalgia (17.4%) affected 4 cases, 3 cases manifested otorrhea (13.0%), and 2 cases presented vertigo (8.7%). Geniculate ganglion was the most commonly involved site (20 cases, 87.0%), followed by tympanic segments (18 cases, 78.3%), pyramid segment (16 cases, 69.6%), mastoid segment (10 cases, 43.5%), labyrinthine segment (9 cases, 39.1%), internal auditory canal segment and parotid gland segment (5 cases, 21.7%, respectively). Twenty-one cases (91.3%) of schwannomas, 1 case (4.3%) of neurofibroma and 1 case (4.3%) of hemangiomas were identified with histopathology postoperatively. The tumors were all completely excised, and the facial nerve function could recovered to HB III at the best after facial nerve repairment. CONCLUSION Facial nerve tumor is a rare and often misdiagnosed disease which was commonly manifested as facial nerve paralysis. Temporal bone CT and MRI can help to clarify the diagnosis preoperatively. Pure tone audiometry and electroneurography also plays a some certain roles in the diagnosis of facial nerve tumors. The tumors should be completely resected and the surgical approaches were determined based on tumor size, facial nerve function and preoperative auditory function.

OBJECTIVE: 10 summarize tne clinical features of the facial nerve tumors involving the internal auditory canal and promote the management of facial nerve tumor. METHOD: We retrospectively reviewed the clinical manifestations, the experiences of diagnosis and treatment of the facial nerve tumor involving the internal auditory canal. All these 5 cases were enrolled during January 2013 to Apr 2015. RESULT: Among the 5 cases, 3 cases were facial neurilemmoma and the others were facial neurofibroma. The main symptoms of facial nerve tumors involving the internal auditory canal most commonly were facial paralysis companied with hearing loss. All the patients accepted the surgical treatment with various approaches, 3 cases of translabyrinthine approach, 1 case of middle fossa approach, and 1 case of combination of translabyrinthine and transotic approach. Total tumor resection were achieved in all 5 cases. Facial-hypoglossal nerve anastomosis was performed in one case, another case was undergone great auricular nerve graft. CONCLUSION Surgical intervention for patients with facial neuroma involving internal auditory canal should be considered when facial weakness has deteriorated to grade 4. The management should be based on the patient's hearing, facial nerve function, tumor size and invasive extension to select the appropriate surgical procedures.

Objective To evaluate the imaging diagnosis value of glomus tympanicum tumors.Methods Images of 10 patients with surgically and pathologically confirmed glomus tympanicum tumors were reviewed.The image characteristics and diagnostic value were summarized.Results In 8 patients with high resolution CT scan and 2 patients with routine CT scan,soft tissue nodules within the tympanic cavity were identified on axial or coronal images in 7 of them.And in 3 patients with chronic tympanitis,glomus tympanicum tumors were not differentiated on CT images.Eight patients had undergone MR examination,on T2WI the tumors were moderate hyperintense(n=6)and hyperintense(n=2),and the tumors were enhanced obviously after contrast.In 3 patients with chronic tympanitis,moderate high signal of the tumor can be differentiated with the high signal of tympanitis on T2WI.On contrast MRI,the signal of enhanced tumor or unenhanced tympanitis was identified clearly.Conclusion On diagnosis of glomus tympanicum tumors,MRI is prior to CT,especially in patient with glomus tympanicum and tympanitis.

Objective To better understand the MSCT characteristic of superior semicircular canal dehiscence syndrome (SSCDS). Methods A retrospective study was conducted on 8 patients who were diagnosed with SSCD syndrome in the otology and skull base surgery group of fudan university. All the patients CT features, the conventional axial and coronal images base on high-resolution MSCT and the images displayed the whole superior semicircular canal, which were reconstructed by using the technology of MPR, were reviewed. Results All the images that displayed the whole superior semicircular canal exhibited the dehiscence. Six patients' dehiscences occur in the middle of the roof over the superior semicircular (4 of 6 dehiscences also occur in the front of the roof), 2 patients dehiscences occur in the back of the roof over the superior semicircular. The range of the maximal diameter of the dehiscence was 0.8-4.2 mm, (median value: 2.4 mm). Conclusion The technology of MPR based on the high-resolution MSCT scan is very useful in diagnosis of the SSCDS.

Objective To evaluate the auditory and verbal abilities of cochlear implantees using question_naires ,to explore basic rules of the development of auditory and verbal abilities ,and to analyze their relationships with some influencing factors .Methods A retrospective analysis of 107 cases of pre-lingually deaf children with cochlear implantation was conducted with Infant-Toddler Meaningful Auditory Integration Scale/Meaningful Audi_tory Integration Scale (IT -MAIS/MAIS) ,categories of auditory performance (CAP) and speech intelligibility rat_ing (SIR) for the evaluation of auditory and verbal abilities .An analysis was performed to assess influencing fac_tors ,such as postoperative time ,age at implantation ,physical age at follow -up ,time with hearing aids before im_plantation .SAS 9 .1 .3 was used in statistical analysis .ResuIts A total of 107 pre-lingually deaf children (48 males and 59 females) participated in this study .The postoperative time ranged from 0 to 49 months ,with an average of 9 .0 ± 10 .9 months .The results showed the postoperative time and age at implantation had significant influences on the scores of IT -MAIS/MAIS ,and postoperative time and physical age at follow -up had significant influences on the scores of CAP/SIR (P<0 .05) ,and hearing aids (HA) usage before implantation had no significant influences on these three questionnaires (P>0 .05) .ConcIusion The ages at implantation ,postoperative time and physical age had significant influences on the auditory and verbal abilities of pre-lingually deaf children with cochlear implanta_tion .Further studies are needed to explore their relationships with hearing aids usage before implantation .

Objective To investigate the pathological mechanism of delayed endolymphatic hydrops(DEH) , and clarify the clinical value of endolymphatic space imaging after intratympanic injection of gadolinium in the diag_nosis of delayed endolymphatic hydrops .Methods Twenty -four hours after bilateral intratympanic injection of gadolinium ,the locations and severity of endolymphatic hydrops of all patients were evaluated by using three dimen_sional fluid-attenuated inversion recovery (3D -FLAIR) and three dimensional real inversionrecovery (3D -real IR) .ResuIts All patients had unilateral or bilateral endolymphatic hydrops .Among 9 ipsilateral DEH patients , only 1 (11 .1% ) patient was identified as mild endolymphatic hydrops and the rest (88 .9% ) examined had signifi_cant endolymphatic hydrops in vestibule of their affected ears ;Endolymphatic hydrops appeared in cochlea of the af_fected ear in 8 (88 .9% ) patients ,except for 1 patient .Endolymphatic hydrops were not observed in the contralater_al ears of 9 ipsilateral DEH patients .Mild endolymphatic hydrops in bilateral vestibule ,severe in right cochlear and none in left cochlea of contralateral DEH patient were identified .ConcIusion Endolymphatic hydrops is the primary pathological factors of DEH .Endolymphatic space imaging after intratympanic injection of gadolinium can intuitively reflect the locations and severity of endolymphatic hydrops in DEH patients .

OBJECTIVE: To evaluate the verbal communication skills of post-lingual cochlear implantees with categories of auditory performance (CAP) and speech intelligibility rating(SIR), and to explore their relationships with the duration of hearing loss, the postoperative time and preoperative hearing aid usage. METHOD: A retrospective analysis was conducted on 23 cases of post-lingual patients with cochlear implantation. CAP and SIR were applied in the evaluation of verbal communication skills. IBM SPSS Statistics 19 was used in statistical analysis. RESULT: The average score of CAP was 6.13, and statistical analysis showed CAP score was not significantly correlated with the duration of hearing loss, the postoperative time or the time of wearing a hearing aid preoperatively. The average SIR score of all these post-lingual patients was 4.91. CONCLUSION It showed that CAP score was not significantly correlated with these three factors. This may due to the low accuracy of CAP or the small sample size in the present study. SIR was not suitable for the evaluation of post-lingual cochlear implantees.

Objective:To analyze the clinical manifestations and the diagnosis of the facial nerve tumor according to the clinical information, and evaluate the different surgical approaches depending on tumor location.Method:Twenty-seven cases of facial nerve tumors with general clinical informations available from 1999.9 to 2006.12 in the Shanghai EENT Hospital were reviewed retrospectively.Result:Twenty(74.1%) schwannomas,4 (14.8%)neuofibromas ,and 3(11.1%)hemangiomas were identified with histopathology postoperatively.During the course of the disease,23 patients(85.2%)suffered facial paralysis,both hearing loss and tinnitus affected 11 (40.7%)cases,5(18.5%)manifested infra-auricular mass and the others showed some of otalgia or vertigo or ear fullness or facial numbness/twitched. CT or/and MRI results in 24 cases indicated that the tumors originated from the facial nerve.Intra-operative findings showed that 24(88.9%)cases involved no less than 2 segments of the facial nerve,of these 24 cases 87.5%(21/24)involved the mastoid protion,70.8%(17/24)involved the tympanic protion, 62.5%(15/24)involved the geniculate ganglion, only 4.2%(1/24)involved the internal acoustic canal(IAC),and 3 cases (11.1%)had only one segments involved. In all of these 27 cases ,the tumors were completely excised,of which 13 were resected followed by an immediate facial nerve reconstruction,including 11 sural nerve cable graft,1 facial nerve end-to-end anastomosis and 1 hypoglossal-facial nerve end-to-end anastomosis.Tumors were removed with preservation of facial nerve continuity in 2 cases.Conclusion:Facial nerve tumor is a rare and benign lesion,and has numerous clinical manifestations.CT and MRI can help surgeons to make a right diagnosis preoperatively.When and how to give the patients an operation depends on the patients individually.

Objective:To explore the influence of blood transfusion on cellular immunofunction in patient with laryngeal carcinoma.Method:EPICS-XL flow cytometry was used to measure T cell subgroup,NK cell and CD28 in 36 patients with laryngeal carcinoma pre-operation and 2 weeks post-operation.Patients were divided into allotransfusion group and non-transfusion group.Comparison was conducted between the 2 groups.Result:①Comparsion with normal population,decreasing of CD3,CD4,NK cell and CD28 in the 36 patients pre-operation was statistically significant (P＜0.01).②Decreasing of CD3,CD4,NK cell and CD28 was statistically signficant post-operation(P＜0.05).③In the non-transfusion group change of CD3,CD4,CD8,NK cell and CD28 post-operation was statistically insignificant (P＞0.05).Conclusion:While cellular immunofunction is generally low in patients with laryngeal carcinoma,allotransfusion will reduce further.It makes contribution to spreading and metastasis of carcinoma easier.

OBJECTIVE: To discuss the diagnosis and management of pulsatile tinnitus of venous origin. METHOD: A retrospective study was conducted on 12 patients who were diagnosed with pulsatile tinnitus of venous origin and treated with ligation of internal jugular veins. We reevaluated the evidences of identifying pulsatile tinnitus of venous origin and reviewed the short-term and long-term postoperative effects and complications. We also reviewed associated articles in this report. RESULT: Seven patients got relief of tinnitus in less than one week after the surgery, while the other 5 patients had no relief. Seven patients were inquired in this study and the other five lost to follow-up. According to the long review (from one to five years postoperatively), two patients who acquired immediate effect got relief of tinnitus, four including complained of no relief and the seventh aggravated into roaring. Three patients who got no immediate relief got no improvement at all. No one in our review complained of any complications. CONCLUSION It's assumed that a history of pulsatile tinnitus, alleviation of tinnitus when pressing jugular veins, tinnitus changing with head position or posture and no occupying lesion in temporal CT scan or cranial MRI are inadequate in diagnosing pulsatile tinnitus of venous origin. Vascular imaging is also necessary to exclude other pathological changes like dura arteriovenous fistula, sigmoid diverticulum and so on. CT arteriography and venography are recommended preferentially. Ligation of internal jugular veins is controversial in patients who have no absence of transverse and sigmoid sinus and identified as pulsatile tinnitus of venous origin.
