Rhinoplasty at GNG Hospital
GNG combines cosmetic rhinoplasty and ENT care, including septal surgery, contracted-nose reconstruction and revision for nasal obstruction.
One plan, distinct goals
Ask which proposed steps address appearance and which address obstruction, with an explanation of why each is needed.
Revision and reconstruction
For a contracted nose or persistent obstruction after surgery, bring previous operation details and ask how they affect the graft and reconstruction options.
Discuss your own anatomy and goals
- Which functional and cosmetic procedures are actually included in my plan?
- Who is my operating ENT surgeon and what relevant cases can I review?
- If implant-free surgery is proposed, what graft material would be used?
Before you decide
Ask to meet the surgeon who will operate, review cases with similar anatomy and confirm the proposed changes in writing. Discuss both appearance and breathing, including what the procedure cannot achieve for your nose.
