Objective To report the curative effect of the epitympanoplasty with cartilage obliteration in the treatment of middle ear cholesteatoma .Methods This study retrospectively analysed 123 cases ,with middle ear cholesteatoma treated in our department from November 2009 to July 2012 .The operation included mastoidectomy with posterior canal wall preserved ,lateral wall of attic resected ,facial recess opened to the epitympanum ,epitym-panum obliterated with cartilage and mastoid cavity blocked with bone dust .All cases were followed up on complica-tions and hearing improvement .Results All cases were followed up 6~38 months .In 123 cases ,there were 2 ca-ses had cholesteatoma recurrence in the middle ear cavity ,6 cases had infection of post auricular incision after opera-tion ,3 cases had residual marginal tympanic membrane perforation ,2 cases had ossicular replacement prosthesis ex-clusion ,and 6 cases had canal wall skin swelling or defect .The rest cases acquired full -recovery after 2 or 3 wound dressing changes .Out of 123 cases ,83 cases had the whole hearing document ,the average AB gap at 0 .5 ,1 ,2 kHz reduced from 32 .2 ± 11 .2 dB pre-operation to 20 .7 ± 12 .4 dB post -operation .The AB gap of pre - and post -operation had significant difference (P<0 .001) .Conclusion The mastoidectomy with posterior canal wall preserved greatly shortened the healing time .The resection of lateral wall of epitympanum can exposed operating field more completely and remove lesions thoroughly .The cartilage obliteration in the attic can prevent the retraction pocket formation effectively .This technique provides alternative in treating middle ear cholesteatoma .

Objective:This article was a retrospective analysis on the preoperative CT scan of fungal sinusitis patients.The non-distinctive clinic feature was suggested to improve the accuracy of preoperative diagnosis.Method:A retrospective analysis was made for 176 patients with fungal sinusitis,which were confirmed by postoperative pathologic disanosis from January 2000 to January 2008.Every patient was performed both CT examination and nasalendoscopy preoperatively. All patients underwent endoscopic sinus surgery and the lesions in sinus were cleared and confirmed fungal infection by pathology.Thirty-five cases fungal infection located in sphenoid sinus,84 cases in maxillary sinus,49 cases in both maxillary and ethmoid sinus,3 cases in all sinus,5 cases in both ethmoid and sphenoid sinus.There were 179 sinuses in 176 patients were infected. Result:This group totally had 175 cases(179 sides). One hundred and seventy-three cases had unibilateral lesion,3 cases had bilateral lesion. The CT scan showed non-distinctive features including unifom dense,uneven dense in the sinus and bone resorption of the inner side bone wall. Five cases in sphenoid sinus lesion were found calcification in CT scan but 8 cases didn't show such features.Among these cases. 5 cases showed uniforra.dense and 3 cases showed uneven dense. In 84 cases maxillary sinus lesion,there were 12 cases without distinctive change,among these cases,8 cases showed uniform derise,4 cases showed uneven dense and 5 cases had boRe resorption. In 49 cases both ethmoid and maxillary sinus lesion,13 cases didn't show distinctive change,among these cases,9 cases showed uniform dense,4 cases showed uneven dense and 6 cases had bone resorption. Five cases had calcification in the both sphenoid and ethmoid sinus. Totally 81.56% of these patients had calcification feature in the CT scan.Conclusion:The calcification in the lesion of sinus is usually featured as characteristic manifestation of fungal sinusitis. But in clinic,the calcification does not exit in some patient's CT scan. When being absent of the featured sign in CT scan,the fungal sinusitis have to be diagnozed by other detecting means,even postoperative pathology.

Objective: To analyze the clinical characteristics and appropriate surgical procedures, and discuss the classification of congenital middle ear malformation. Methods: All cases were from the Center of Otorhinolaryngology, the Sixth Medical Center of Department of PLA General Hospital. All of these cases, including 26 male patients (ears) , 10 female patients (11 ears) , aged from 7 to 57 years old, had normal external auditory canal, tympanic membrane, conductive hearing loss, type A tympanogram and negative Gelle′s test. Tympanoplasty was performed in all cases. The deformity was classified to three types,i.e., Type I (stapes foot plate mobility): Ⅰa, ossicular chain deformity with normal stapes suprastructure; Ⅰb, ossicular chain deformity with abnormal stapes suprastructure; Type Ⅱ (stapes foot plate fixation): Ⅱ a,normal ossicular chain, Ⅱ b, ossicular chain malformation; and Type Ⅲ: vestibular window osseous atresia or undeveloped, or with round window atresia. The malformation of type Ⅱ and Ⅲ may be accompanied with abnormal facial nerve. In addition, the papers on middle ear malformation published from 1982 to 2017 were analyzed retrospectively. The clinical data of 451 ears malformation were summarized. Results: According to the revisional classification criteria in 37 ear samples from our hospital, 20 ears were type I. 6 type Ⅰa cases were used PORP (partial ossicular replacement prosthesis) to reconstruct the ossicular chain; 14 type Ⅰb cases were used TORP (total ossicular replacement prosthesis) to reconstruct the ossicular chain. For the 5 ears of type Ⅱ, 2 of which were type Ⅱ a and 3 were type Ⅱ b. 4 ear samples of type Ⅱ were implanted with Piston ossicular prosthesis, 1 was implanted with TORP in which the ossificated foot plate was removed with periosteum preserved. 12 ear samples were type Ⅲ, with vestibular window osseous atresia, facial nerve malformation, and stapes suprastructure malformation. The pistons ossicular prosthesis were implanted in vestibular window in 3 ears with facial nerve covering vestibular window partially. The surgery had to be given up in 5 ears, and TORP was implanted in 4 ears at the opening with preserved periosteum at the beginning of the tympanic scala because of facial nerve covering vestibular window totally. 30 ears with complete follow-up data had no sensorineural hearing loss and the average air-bone conduction decreased 23.3±10.7 dB (P<0.05).There were 234 ears of type Ⅰ in 451 ears of congenital middle ear malformation reported in the literature. 113 of which were type Ⅰa, the basic surgery was ossicular chain shaking and artificial or autogenous PORP implantation. Type Ⅰb was 121 ears, with autogenous or artificial TORP and PORP. Type Ⅱ was125 ears, including type Ⅱa 22 ears, Ⅱb 60 ears, and no subclassification for 43 ears. The surgery of type Ⅱ was the same as otosclerosis. The vestibular window atresia of type Ⅲ was 92 ears, the surgery of 17 ears had to be abandoned, the other ears underwent vestibular window, promontory or semicircular canal opening to reconstruct hearing with Piston, autogenous or artificial TORP. Conclusion Referring to the classification of congenital middle ear malformation combining with appropriate surgical materials and methods, otologists can better understand and choose appropriate surgical method to the middle ear malformation.
