PRE-SURGERY TESTS AND INVESTIGATIONS FOR ENT SURGERY

Before going for an “elective” or planned procedure you need to get these tests done-

 

FOR PAEDIATRIC PATIENTS (UP TO 16 YEARS OF AGE)

 

INVESTIGATION

  • Complete blood count
  • PT/INR, Bleeding, and clotting time
  • Nasal secretions for culture or (cerebrospinal fluid) analysis (in case of suspected fungal disease or CSF leak)
  • X-ray nasopharynx (in case of adenoid surgery)
  • X-ray mastoid or HRCT temporal bone (in case of ear surgery)
  • X-ray PNS or HRCT nose and PNS (in case of nose surgery)
  • ECG Or X-RAY CHEST (your pediatrician might ask these tests if required for pre-surgery clearance)
  • CT CISTERNOGRAPHY (in case of CSF leak)

 

TEST

 

  • Nasal Endoscopy
  • Otoscopy (ear endoscopy)
  • Pure tone audiometry (for ear surgery)
  • Impedance audiometry
  • OAE and BERA (for cochlear implant surgery)
  • Impedance tympanometry (for ear surgery)
  • Fiber-optic laryngoscopy (for larynx/ vocal cord surgery)
  • FNAC (fine needle aspiration cytology) – for lymph node, gland, or tumor-like swellings

 

FOR ADULT PATIENTS (17 TO 40 YEARS OF AGE)

 

INVESTIGATION

 

  • Complete blood counts
  • Random blood sugar
  • Kidney function test
  • PT/INR
  • Viral serology- HIV, HCV, ANTI HBs
  • ECCG
  • XRAY CHEST
  • URINE ROUTINE AND MICROSCOPY
  • Nasal secretions for culture or (cerebrospinal fluid) analysis (in case of suspected fungal disease or CSF leak)
  • X-ray mastoid or HRCT temporal bone (in case of ear surgery)
  • X-ray PNS or HRCT nose and PNS (in case of nose surgery)
  • MRI related to Ear, Nose Throat region
  • CT CISTERNOGRAPHY (in case of CSF leak)

 

TEST

 

  • Nasal Endoscopy
  • Otoscopy (ear endoscopy)
  • Pure tone audiometry (for ear surgery)
  • Impedance tympanometry (for ear surgery)
  • OAE and BERA (for cochlear implant surgery)
  • Fiber-optic laryngoscopy (for larynx/ vocal cord surgery)
  • Sleep endoscopy (if surgery is for sleep apnea)
  • Polysomnography (PSG)or sleep study (if surgery is for sleep apnea)

 

FOR ADULTS MORE THAN 40 YEARS OF AGE

 

INVESTIGATION

 

  • Complete blood counts
  • Random blood sugar
  • Kidney function test
  • Liver function test
  • PT/INR
  • Viral serology- HIV, HCV, ANTI HBs
  • ECCG, 2D ECHO
  • XRAY CHEST
  • URINE ROUTINE AND MICROSCOPY
  • X-ray mastoid or HRCT temporal bone (in case of ear surgery)
  • X-ray PNS or HRCT nose and PNS (in case of nose surgery)
  • USG ABDOMEN (In case of bladder related complaints to rule out prostate hypertrophy)
  • Pulmonary function tests (in case you are already suffering from a lung disease like COPD)
  • Nasal secretions for culture or (cerebrospinal fluid) analysis (in case of suspected fungal disease or CSF leak)
  • CT CISTERNOGRAPHY (in case of CSF leak)

 

TEST

 

  • Nasal Endoscopy
  • Otoscopy (ear endoscopy)
