Carbon Dioxide (CO2)-Laser Tympanostomy

                                 Before                                                              After

 

CO2-laser tympanostomy is an alternative method to the standard myringotomy and grommet insertion.  It is ideal for the purpose of short-tem middle ear ventilation for example in subacute middle ear effusion, barotrauma, and acute otitis media.  It has the advantages of simplicity, precision, good homeostasis, and low risk of non-closure.  Obviously, no grommet is left in-situ;

thus avoiding tube-related issues.

 The appearance of tympanic membrane one month after myringoplasty.  Remnant of temporalis fascia is still seen (+).  The fascia acts as a scaffold for new epithelial growth to bridge the defect.  The remnant will thin out over time to make it more compliant for sound energy transfer.

Teflon piston anchored at long process of incus with its tip seen in the stapedotomy hole.  Gelfoam was added to cover the opening around the piston tip.

Endoscopic Stapedotomy & Tympanoplasty

Cholesteatoma Surgery

Principles:

 

i.Removal of all diseased cells and mucosa.

ii.Creation of a single, smooth, non-doctor dependent, non-discharging cavity with good hearing preservation and no dizziness.

Cortical Mastoidectomy

This is an operation in which the mastoid antrum and air cells are converted into single cavity with preservation of middle middle ear content. 
 
Its indications include:
i. Acute mastoiditis not responding to medical therapy.
ii. Mastoid abscess.
iii. Recurrent or chronic otitis media in which diseased mastoid suspected to be the reservoir of infection.
iv. As preliminary approach to other surgical procedure e.g. cochlear implant, vibrant soundbridge placement, facial nerve decompression, etc.
