How we do it

17 operations described the way they are planned and performed at Santosh Advance ENT Healthcare, Hisar: indication, choice of approach, operative steps in sequence, the landmarks that keep the operation safe, and the recovery that follows. Each guide links to the operative video, the referenced case report where one exists, and the relevant book chapter.

For professional education. Steps are summarised and vary with the patient, the disease and the surgeon; they do not replace supervised training or local protocols. Operative videos are shown with patient consent and without identifying the patient.

Ear and lateral skull base

Otology · intermediate

Tympanoplasty (type I) with ossicular assessment

Indications

Dry central perforation of the pars tensa with conductive hearing loss or recurrent discharge, after the ear has been dry for several weeks and the audiogram confirms the air–bone gap.

Approach

Endoscopic transcanal for most anterior and central perforations; microscopic post-aural when the canal is narrow, the anterior margin is hidden or the mastoid must be explored.

Operative steps

  1. Freshen the perforation margin and remove the rim of epithelium.
  2. Elevate the tympanomeatal flap from about the 6 to 12 o'clock position and enter the middle ear at the annulus.
  3. Inspect the ossicular chain: mobility of the malleus, continuity of the incudostapedial joint and mobility of the stapes.
  4. Harvest temporalis fascia or tragal perichondrium and dry it.
  5. Place the graft as an underlay medial to the remnant and malleus handle, supported by absorbable gelatin sponge in the middle ear.
  6. Replace the flap and pack the canal.

Landmarks and safety

  • Chorda tympani lies just under the posterosuperior annulus; elevate it with the flap.
  • Avoid suction on a mobile stapes.
  • The facial nerve can be dehiscent over the oval window.

After surgery

Keep the ear dry; canal pack removed at two to three weeks; audiogram at about three months.

Otology · advanced

Mastoidectomy for cholesteatoma: canal wall up and canal wall down

Indications

Cholesteatoma or chronic otitis media with mastoid disease. Canal wall up when disease can be cleared with the posterior wall intact and follow-up is reliable; canal wall down for extensive disease, a contracted mastoid, or when a second-look operation is unlikely.

Approach

Post-aural incision, musculoperiosteal flap, cortical drilling within Macewen's triangle.

Operative steps

  1. Identify the spine of Henle, temporal line and posterior canal wall.
  2. Drill the cortex and open the antrum; identify the lateral semicircular canal and the short process of the incus.
  3. Thin the tegmen and sinodural angle; follow the disease into the attic and facial recess.
  4. Canal wall down: lower the posterior wall to the level of the facial ridge, saucerise the cavity and perform an adequate meatoplasty.
  5. Remove the matrix completely, then reconstruct the drum and, where possible, the ossicular chain.

Landmarks and safety

  • The lateral semicircular canal and the incus are the guide to the facial nerve's second genu.
  • Drill parallel to the facial nerve with continuous irrigation.
  • Do not open the dura or sigmoid sinus while thinning the plates.

After surgery

Mastoid dressing for 24 to 48 hours; regular cavity care; second-look surgery or diffusion-weighted MRI for canal wall up.

Otology · advanced

Endoscopic stapedotomy

Indications

Otosclerosis with conductive loss, an air–bone gap of about 25 dB or more, and a negative Rinne at 512 Hz.

Approach

Transcanal endoscopic, with a tympanomeatal flap and removal of posterosuperior canal bone (scutum) until the stapes and pyramidal process are seen.

Operative steps

  1. Confirm stapes fixation and a mobile malleus and incus.
  2. Measure from the long process of the incus to the footplate.
  3. Divide the stapedius tendon and separate the incudostapedial joint.
  4. Remove the stapes superstructure.
  5. Make a small fenestra in the footplate with a microdrill or laser.
  6. Place a piston of measured length and crimp it on the incus; seal the fenestra with tissue.

Landmarks and safety

  • Avoid opening the vestibule widely; a floating footplate is a recognised hazard.
  • A dehiscent facial nerve may overhang the oval window.

After surgery

Avoid nose-blowing and straining; vertigo is usually brief; audiogram at six weeks.

Otology · advanced

Cochlear implantation

Indications

Bilateral severe to profound sensorineural hearing loss with limited benefit from hearing aids, after audiological, imaging and counselling assessment.

Approach

Post-aural incision, cortical mastoidectomy and posterior tympanotomy through the facial recess to the round window.

Operative steps

  1. Mark the receiver–stimulator position and drill the seat and tie-down.
  2. Cortical mastoidectomy; identify the short process of the incus.
  3. Open the facial recess between the facial nerve and the chorda tympani.
  4. Identify the round window niche and remove its overhang.
  5. Insert the electrode slowly through the round window membrane.
  6. Seal the opening with tissue, fix the device and perform intraoperative telemetry.

Landmarks and safety

  • The facial recess is bounded by the facial nerve medially and the chorda tympani laterally.
  • Atraumatic, slow insertion preserves residual hearing.
  • Check imaging for cochlear malformation or ossification before surgery.

After surgery

Switch-on at about two to four weeks, followed by mapping and auditory rehabilitation.

Lateral skull base · advanced

Lateral skull base approach for glomus jugulotympanicum with facial nerve grafting

Indications

Glomus tumour extending from the middle ear to the jugular bulb, after imaging, angiography and assessment of lower cranial nerves.

Approach

Infratemporal fossa approach (type A pattern): canal closure, mastoidectomy, control of the sigmoid sinus and internal jugular vein in the neck, and facial nerve management.

Operative steps

  1. Expose the great vessels and lower cranial nerves in the upper neck.
  2. Close the external canal as a blind sac and perform a radical mastoidectomy.
  3. Skeletonise or reroute the facial nerve as the tumour requires.
  4. Control the sigmoid sinus proximally and the internal jugular vein distally.
  5. Remove the tumour from the jugular bulb and middle ear.
  6. Reconstruct the facial nerve with a cable graft where it is involved; obliterate the cavity.

Landmarks and safety

  • Lower cranial nerves (IX–XI) lie on the medial wall of the jugular bulb.
  • Bleeding from the inferior petrosal sinus is controlled with packing, not cautery.

After surgery

Swallowing assessment; eye care until facial function returns; imaging surveillance.

Nose, sinuses and anterior skull base

Rhinology · beginner

Endoscopic septoplasty

Indications

Deviated septum or septal spur causing nasal obstruction, or limiting access for sinus surgery.

Approach

Endoscopic, through a hemitransfixion or Killian incision; targeted to the deviated segment.

Operative steps

  1. Infiltrate and make the incision on the side of the deviation.
  2. Raise the mucoperichondrial flap and cross under the cartilage to the opposite side.
  3. Remove or reposition the deviated cartilage and bony spur, preserving an L-strut.
  4. Check the airway endoscopically on both sides.
  5. Close the incision and place quilting sutures or splints.

Landmarks and safety

  • Keep at least 1 cm of dorsal and caudal strut to protect nasal support.

After surgery

Calcium monitoring; voice check; thyroid hormone replacement.

Oral cavity, neck and salivary glands

Head and neck oncology · intermediate

Partial glossectomy with selective neck dissection

Indications

Carcinoma of the oral tongue, staged clinically and on imaging; neck dissection is advised for most tumours because of the risk of occult nodes.

Approach

Transoral for most tongue tumours; a lip-split or pull-through approach only when access requires it.

Operative steps

  1. Mark a margin of about 1 cm around the palpable tumour.
  2. Excise in three dimensions, palpating for depth.
  3. Send margins for frozen section where available.
  4. Close primarily or reconstruct with a local or free flap.
  5. Perform the selective neck dissection (levels I–III or I–IV).

Landmarks and safety

  • Preserve the lingual nerve and hypoglossal nerve unless involved.
  • Depth of invasion guides the decision on the neck.

After surgery

Swallowing and speech therapy; review of histology for adjuvant treatment.

Head and neck oncology · intermediate

Selective neck dissection, level by level

Indications

Staging or treatment of the neck in head and neck cancer, with levels chosen by the primary site.

Approach

Operative steps

  1. Raise the skin flap over the parotid fascia.
  2. Mobilise the gland from the sternocleidomastoid and the cartilaginous canal.
  3. Identify the facial nerve trunk using the tragal pointer, the posterior belly of digastric and the tympanomastoid suture.
  4. Follow the branches forward, lifting the gland off the nerve.
  5. Remove the tumour with a cuff of normal tissue; sacrifice the nerve only when it is involved, and graft where possible.

Landmarks and safety

  • The nerve trunk lies about 1 cm deep and inferior to the tragal pointer.
  • Nerve monitoring and a dry field help in revision surgery.

After surgery

Facial nerve assessment; drain care; watch for salivary collection.
