Thank you Prof Magdy.
Many thanks indeed. I am glad you found it helpful
Amazing lecture… thanks for sharing 👏🏻
My pleasure!
Please Dr What is the best choice in patient with scalp scar about 4x3cm in bt temporal and occipital area above the ear ?
If the defect is above the hairline, then single or double rotation flaps may be considered. Alternatively if the defect is Large triple rhomboid flaps may be considered as well
Have you written and printed a manual and recorder all videos, prof. Magdy? Can they be bought? I can only congratulate you on the way you present this topic with ease and clarity!
I have recorded about 2 dozens of videos for flaps and more for techniques for closing defects. I think this is a better teaching method. Many thanks for your feedback
I am an oculoplastic fellow, will I also benefit from your presentations on flaps or they are tailored to ENT residents? Thanks.
I have uploaded 2 playlists on flaps and techniques to close a defect, I think some of them would be relevant to your specialty as well
Every time I operate a thyroid this lecture is my must revise lecture. Thank you for being an awesome teacher

You are phenomenal, this has been a point of confusion I had for years! Thank you!
You are most welcome. I'm glad you found it useful
Thank for this lecture Prof Magdy. The budding tree appearance was something new for me as a medical student and I thoroughly enjoyed this video. Is it possible sir if you can talk about deep neck space infections? It is a topic that I feel is not usually covered in medical school and I would love to learn more about it from you professor. Thank you Prof. Magdy.
Many thanks indeed. I am sharing now my Salivary presentations, soon afterwards I shall share deep neck space infections instantly Àllàh

This is the best explanation I"ve seen for these flaps! It's also a great way of showing how great youtube can be- how else would dermatologists in San Francisco be learning from ENT surgeons in Egypt?
Many thanks indeed. Very kind of you. I am happy you found it helpful.
Thank you for this session Prof. Magdy. I am a 5th year medical student and I have a deep interest in otolaryngology. These lectures are very helpful and useful for understanding and fueling my passion. I hope one day to become great otolaryngologist like you.
I am really glad to hear that you found it useful. All the best wishes for your career
I found out from a Doctor that recurrent tongue and mouth ulcers have been linked to MTHFR gene mutation. Unable to methylate folic acid (synthetic form of B9 Folate). 1.Solving is easy Stay away from grains and flour that says fortified because it means it was sprayed with folic acid. 2. take bioavailable form of B9 folate. and eats foods that is high in folate not folic acid. The most richest source of bioavailable folate is liver.
blessed to have such a practical lecture . thank you 👏
Glad it was help ful!. Thanks for your kind çomment

Dear doctor, I can’t seem to find the first part. Can you kindly re-upload it?
Yes, it will be updated and ready uploaded in due course. Thanks for your interest
The updated part 1 is now uploaded.
thank you for the reply. In this regard, today in 2024, could you recommend a surgeon in Europe who really has experience with this type of surgery?
A Specialist Thyroid surgeon should be able to do the surgery with all the required skills and experience and take the necessary precautions. I am sorry I am not able to specify any names
Thank you professor for this video
You are welcome. I'm glad you found it helpful
Hi, I wanted to ask if the incidence of damaging the non-recurrent nerve is almost 5 times higher than with a classic operation because it is damaged when you look for it when you intervene surgically expecting it to be in a normal position, and therefore the surgeon makes the mistake at that moment, or because, once recognized without having damaged it, it is still in a more delicate position compared to a normal nerve and therefore there is a greater possibility of damaging it. Thank you
The non recurrent laryngeal nerve may be overlooked as surgeons would be focusing on the usual path of the nerve and may accidentally stretch or cut structures away from that path
Thought provoking indeed. But the devil is in many many details.
Hamdy,big data (tens of thousands) produced clear trends on both sides of the argument. Multiple regression can suggest a root cause(s), but there remains missing pieces of the jigsaw.
Thank you so much prof!
Many thanks. Very kind of you.
Dear prof. :there's a research proved that Azythromycin has an anti viral effect besides its effect against gr. +ve bacteria and the atypical bacteria like the chlamedia. So, (from my own experience) I give Azythromycin early if there no pus on the tonsils. But if there is pus I begin by cephalosporins (bacterial infection) . Presence of pain or not isn't a reliable measure as it is a personal experience and patient's reaction to it depends on his or her social and psychological background
Many thanks for your comments. Cephalosporins have a very mild and statistically insignificant advantage over penicillin in reducing symptoms by few hours. The number needed to treat to save a single sore throat case this insignificant time is 20 patients and NNTto reduce relapse rate by single case is 50. You need to consider the costs of treatment for 20 or 50 patients by ceohalosporins to save single extra case, and also consider the risk of antibiotic resistance if you use it in a very common condition with no significant advantage. Penicillin resistance has not developed in the last 50 years. As for Azathioprine the meta analysis showed no advantage at all over penicillin and a significant higher adverse reaction rate up to 5 times that of penicillin. There are much more data on this in .y lecture on sore throat which antibiotic. Kind regards
Thanks prof Magdy
Thank you very much
