RESUMO
Objective To investigate the clinical effects of autologous mastoid cortex in canal wall -down tympanoplasty .Methods From Jun 2015 to Jan 2016 ,40 patients with chronic suppurative otitis media were ran-domly divided into the experimental group and control group ,with 20 patients in each group .Patients in the experi-mental group were treated with autologous cortical bone on the tympanic cavity reconstruction surgery + opening tympanoplasty + mastoid cavity filling surgery ,the control group received opening tympanoplasty only .All cases were followed up for 1 year to compare postoperative dry ear and hearing improvement in the two groups .Results The dry ear rate of the experimental group was (100％ ) higher than that of the control group (70％ ) .The hearing of the two groups was significantly improved(23 .42 ± 0 .90 dB) in the experimental group ,higher than that in the control group (8 .43 ± 0 .04 dB) at 6 months after operation .Conclusion Using autologous cortical bone on the tympanic cavity reconstruction in the treatment of chronic suppurative otitis media is effective .The postoperative dry ear rate is high and the hearing improvement is excellent .
RESUMO
OBJECTIVE@#A retrospective analysis of the clinical efficacy on the surgery of maxillary sinus diseases via the endoscopic lateral nasal wall incision, and a discussion on the clinical application of this approach.@*METHOD@#Eighteen cases of the maxillary sinus diseases diagnosed on the basis of the preoperative nasal endoscopy, CT scan or MRI, and pathologic finding. Among 13 patients underwent routine lateral nasal wall incision approach, including 4 of maxillary sinus hemorrhagic and necrotic polyps, 4 of maxillary sinus cyst, and 3 of the maxillary sinus fungal infection. Five patients underwent lateral nasal wall resection approach and thorough maxillary sinus lesions resection by nasal endoscope, including 3 of inverted maxillary sinus papilloma, a nasal sinus bone giant cell tumor and a spindle cell tumor. Patients were followed up for more than half a year, and the postoperative efficacy were observed.@*RESULT@#The surgical cavity of the lateral nasal wall incision approach have luminal epithelium, well shapes of inferior turbinate, no recurrence of the lesion, and the lateral nasal wall resection patients with well luminal epithelium, without recurrence. All patients had no complications such as numbness, tears, etc.@*CONCLUSION@#Endoscopic incision of lateral nasal wall keep the nasolacrimal duct and inferior turbinate, help remove the entire sinus cavity lesion and retain the physiological function of the nasal cavity. Resection of the lateral nasal wall can reveal an ideal vision approach, which perform certain clinical value for the treatment of the inverted maxillary sinus papilloma and sinus cancer.
