ABSTRACT
Otosclerosis is one of the common causes of hearing loss. The incidence varies between 0.1% and 2%. In Lebanon otosclerosis is a common entity that has not been well evaluated. To the best of our knowledge there is no epidemiologic analysis of the incidence or outcomes of otosclerosis in Lebanon. We collected the number of stapedectomies performed for otosclerosis in different hospitals between Jan. 1994 and Dec. 1995. We also retrospectively reviewed the charts of 71 cases who underwent stapedectomy at Hotel-Dieu de France - St Joseph University Hospital Medical Center, Beirut, Lebanon.Between 1992 and 1996 the incidence of otosclerosis in Lebanon as revealed through stapedectomy is 5/100 000.We report also on the pathology, technique, complications and outcomes of stapedectomy surgery for otosclerosis in Hotel-Dieu Hospital. Further epidemiologic studies and screening is required to reveal the exact incidence of this common entity that could be underdiagnosed or untreated in our country

Chronic suppurative otitis media [CSOM] is a common disease especially in developing countries. In Lebanon, CSOM is a frequent complaint. This retrospective study is an objective evaluation of the cases we operated in HDF.One hundred and forty cases of CSOM were collected between 1993 and 1997: 88/140 cases were simple CSOM and the others 52/140 cases had cholesteatomas. There were no immediate postoperative complications reported [< 6 weeks]. Beyond 6 weeks, with a mean follow-up of 20 months, 15% of the patients were lost for follow-up and we had 93.4% of success rate in CSOM and 88% in cholesteatomas. The recurrence rate of cholesteatoma was 14%. Children's cholesteatoma [below 15 years of age] were more aggressive than adult's cholesteatomas. In CSOM without cholesteatoma, the hearing gain was 5 dB. In CSOM with cholesteatoma the mean hearing gain was 4 dB. In conclusion the study revealed the importance of this pathology in our country with the relative high incidence of cholesteatoma compared to simple CSOM, this could be explained by the chronicity of the disease and the lack of preventive measures
