ABSTRACT
OBJECTIVE To explore the application value of the cortical bone packing in external auditory bony canal and attic reconstruction in tympanoplasty.METHODS A total of 30 patients admitted during the period of middle ear cholesteatoma patients in our hospital from March 2014 to March 2016,were randomly divided to observation group and control group,the radical mastoidectomy with canal wall down was adopted in the control group,the radical mastoidectomy with canal wall down combined with bone autograft in the external auditory meatus and bony powder mastoid obliteration in observation group,the postoperative out-come between two groups were compared.RESULTS There was no significant difference between the speech frequency average air bone conduction and air conduction threshold before the treatment in two groups.There was significant difference between the speech frequency average air bone conduction and air conduction threshold after the treatment(P＜0.05),the air conduction threshold significantly reduced,the patients in the observation group were significantly lower than the control group,there was no recurrence of cholesteatoma in two groups of patients before and after the treatment during follow-up period;the dry ear time in observation group was significantly lower than that of the control group,and dry ear the incidence was significantly higher than that of the control group,the difference is statistically significant(t=2.758,4.865,P＜0.05).CONCLUSION Radical mastoidectomy with canal wall down combined with the cortical bone packing in external auditory bony canal and attic reconstruction,can effectively presesre the patient hearing,it should be recommended.
ABSTRACT
Objective To investigate and evaluate the clinical effect of the application of medical adhesive in limited septoplasty by endoscope.Methods 57 patients were selected to undergo operation of limited septoplasty by endoscope.The patients were divided into packing group and bonding group.The packing group had 29 patients,whose nasal cavity was packed with vaseline gauze.While the bonding group had 28 patients,their nasal septum mucosa was adhesive fixed by medical adhesive,and the nasal cavity without packing.The indexes included the cardinal symptoms(nasal pain and headach,sleep status),signs (seepage amount of bleeding,mucosal edema),degree of discomfort in nasal cavity processing after operation(pain and bleeding) and length of stay were compared between the two groups.Results The above indexes in the bonding group were apparently lightened than the packing group and the length of stay was shortened.The differences were statistically significant (all P ＜ 0.05).Conclusion In operation of limited septoplasty by endoscope,the using of medical adhesive replacing nasalpacking could reduce the trauma on patients by operation and lighten the pain.The curative effect is satisfactory and it has excellent clinical application value.
