🧠 INTP Study Guide: ENT & Eye Surgical Concepts
🩺 1. Surgical Procedures & Terms
Rhinoplasty
➤ Not just cosmetic. Also corrects breathing issues.
✅ False (Rhinoplasty can be medical)Septoplasty
➤ Fixes deviated nasal septum
✅ DefinitionLaryngectomy
➤ Removal of part/all of larynx (for cancer)Tracheotomy
➤ Incision in neck → airway access
✅ Used when upper airway is blockedMyringotomy
➤ Small hole in eardrum to drain fluidTympanoplasty
➤ Repairs perforated eardrumStapedectomy
➤ Removes stapes bone to treat hearing lossMastoidectomy
➤ Removes infected cells in mastoid boneAdenoidectomy
➤ Removes adenoids causing blockageTurbinectomy
➤ Improves airflow by removing turbinates
👁 2. Eye Procedures
Strabismus Surgery
➤ Realigns extraocular musclesPPV (Pars Plana Vitrectomy)
➤ Removes vitreous humor
➤ Silicone oil used temporarily (must be removed, not absorbed)
➤ Face-down positioning often requiredCataract Surgery
➤ Uses ultrasonic probe to break lens (phacoemulsification)Trocar Insertion
➤ Uses speculum/retractor first, then cannula or guide
➤ Instrument used: cannula introducer or speculum, not just “retractor”
🧪 3. Grafts & Transplants
Type | Source |
|---|---|
Autograft | Same person |
Allograft | Same species |
Xenograft | Different species (e.g., animal) |
Synthetic | Man-made materials |
👂 4. Hearing & Ear Disorders
Otitis Media
➤ Middle ear infectionOtitis Externa
➤ Swimmer’s ear (outer ear inflammation)Tinnitus
➤ Ringing or buzzing in ears (not inflammation!)Conductive Hearing Loss
➤ Problem in outer/middle earSensorineural Hearing Loss
➤ Inner ear/auditory nerve damageCochlear Implant
➤ Bypasses damaged hair cells
➤ Restores hearing, not balance
👃 5. Sinus Surgeries
Procedure | Purpose |
|---|---|
FESS | Opens sinuses via endoscope |
Caldwell-Luc | Access maxillary sinus |
Balloon Sinuplasty | Minimally invasive sinus dilation |
Nasal Polypectomy | Removes airflow-blocking polyps |
💉 6. Anesthesia Types & Uses
Type | Common Use Case |
|---|---|
Topical | Surface numbing (eye surgeries) |
Local | Small area (injection) |
Regional | Larger body part (e.g., nerve block) |
General | Full sedation (complex ENT surgeries) |
💧 7. Eye Anatomy & Fluids
Vitreous Humor
➤ Gel-like fluid, maintains eye shapeBSS (Balanced Salt Solution)
➤ Used in eye surgeries to maintain moisture
🧬 8. Misc Concepts
Macular Degeneration
➤ Damages retina, causes vision loss
✅ TrueTurbinates
➤ Warm & moisten inhaled airCommon Complication of Chronic Otitis Media
➤ Hearing LossStretching the Esophagus
➤ Balloon dilation
➤ Bougie dilation
