الهدف من البحث: يهدف هذا البحث إلى دراسة و مقارنة نسبة النكس التالي لاستئصال الورم الكولستريني عند التداخل الجراحي بإجراء حج العلية مع تلك التالية لحج الخشاء بالطريقة المغلقة. طريقة إجراء الدراسة: شملت عينة الدراسة 57 مريضاً تم قبولهم في الشعبة الأذنية في مستشفى المواساة الجامعي بتشخيص التهاب أذن وسطى مزمن مع ورم كولستريني. خضع المرضى لحج العلية في 30 حالة، و حج الخشاء بالطريقة المغلقة في 27 حالة، تمت متابعهم لمدة سنتين و مراقبة و تقييم الأعراض مع الأخذ بالاعتبار الحاجة إلى التداخل الجراحي اللاحق بهدف تصنيع العظيمات. النتائج: بلغت نسبة النكس في حالات حج العلية 23.33%، و في حالات حج الخشاء بالطريقة المغلقة 22.21%. إن حج الخشاء بالطريقة المغلقة فاق طريقة حج العلية في السيطرة على القشور الكولسترينية المنتشرة (الورم الكولستريني المنتشر). الخلاصة: يمكن الاكتفاء بحج العلية في حالات الورم الكولستريني الكيسي المحدود، و لكن يبقى حج الخشاء بالطريقة المغلقة هو الطريقة المفضلة لحالات التهاب الأذن الوسطى مع الورم الكولستريني المنتشر.
Aim: To evaluate and compare the rate of cholesteatoma recurrence after Atticotomy surgery to that after Canal Wall Up Mastoidectomy (CWU). Material and Methods: The study involved 57 patients admitted to the ENT Department Almoassat Hospital. Atticotomy was performed in 30 cases, whilst CWU mastoidectomy within 27 cases. Follow up period was extended for two years to compare the symptoms and the necessity for second Ossiculoplasty surgery. Results: The recurrence rate was 23.33 % within atticotomy group, whilst it was 22.21 % in CWU group. CWU mastoidectomy showed better outputs in diffused cholesteatoma cases. Conclusion: A limited cystic cholesteatoma can be treated effectively by atticotomy, however CWU mastoidectomy remains the favorable technique to manage a diffused cholesteatoma.

The primary goal of any surgery for cholesteatoma is complete
eradication of this lesion aiming to reach a dry ear and to prevent the
complications and recurrence. The second goal is to preserve hearing or to
improve it. This study aims to discuss
cases of Cholesteatoma treated by
canal wall-up mastoidectomy (Closed technique) and to determine the
efficacy of this technique by studying the recurrence rates and hearing
results.
The necessity of Meatoplasty In Radical Mastoidectomy for good postoperative
cleaning of mastoid cavity and to reduce recurrence rate.This study aim to evaluate the results of
Meatoplasty By Rotating door flap method In Radical or modified radical
Mastoidectomy (open
technique).
Objectives: to analyse the incidence of facial nerve dysfunction following
parotidectomy and to correlate this with the extent of parotid gland resection, and the
pathological diagnosis.
Between 2010 – 2014, 35 patients underwent 35 parotidectomie
s performed by the
same surgeon.
Results: the incidence of initial postoperative facial weakness was 37,14%, based on
the diagnosis and extent of surgery, rates of facial weakness were 23,1%, 30,8% and
46,1% for superficial parotidectomy, total parotidectomy and total parotidectomy
associated with a neck dissection respectively.
Permanent weakness occurred in 7,7% of patients, recovery of normal facial
movements occurred within 6 months in all patients with initial temporary facial weakness.
Objective : to analyze the level (site) of ipsilateral neck recurrences after
supraomohyoid neck dissection in patients with lip, oral and oropharyngeal cancer treated
in a single institution.
Between 2010 – 2013, 38 patients underwent 38 supraomo
hyoid neck dissection.
Results: there were 5 cases (13%) of ipsilateral neck recurrences, 2 were beyond the
limits of the supraomohyoid neck dissection, and 3 were inside these limits. There was no
association of neck recurrences with pathological status of lymph nodes. 4 of the 5
recurrences were in patients who underwent postoperative radiotherapy.
The objective of this study was to compare the effect of using intravaginal sponges with intramuscular (IM) injection of prostaglandin hormone within the reproductive season and their effect on Lambing rate and birth rate in Awassi ewes. Thirty ewes
were equally divided into two groups (G1 and G2). Intravaginal sponges impregnated with 60 mg of Medroxy
Progesterone Acetate (MAP) were inserted into the ewes of the first group for 14 days, and were injected at the time of the withdrawal of sponges with 500 IU of equine Chorionic Gonadotrophin (eCG) at the first group ewes (G1). The ewes in second group (G2) were
injected with double dose of 125 μg of prostaglandin (PGF2α) intramuscularly (IM) at 9 days apart. The ewes were naturally mated with fertile rams (ram / 5 ewes). The results showed that there were significant differences between groups (G1 and G2) in the Lambing rate (93.33% vs. 73.33%). The ewes of group (G1) outperformed the ewes of group (G2) in the
percentage of twin births (42.86% vs. 18.18%), and the birth rate (1.43 vs. 1.18) with significant differences (P<0.05). We conclude from the study that treating ewes by using intravaginal sponges with eCG injection was better than the method of prostaglandin
injection in raising the Lambing rate and birth rate in Syrian Awassi ewes, within the local Syrian conditions
