A purposive sampling of all patients attending the ENT clinics at AIIMS OPD will be undertaken. Patients with Unilateral Microtia will be evaluated and those fulfilling the inclusion and exclusion criteria will be recruited. They will be screened for severe facial abnormalities, chest wall abnormalities and low hairline microtia. Those deemed unfit for surgery under General Anesthesia by the Anesthesiology team will be excluded and will be provided other suitable alternative treatment options.

Patients recruited for the study will be explained in complete detail about the procedure and an Informed Written consent will be sought.

Following this, detailed workup and assessment of the patients will be done and a basic proforma including demographic and clinical details will be filled.

Clinical Photographs for medical, research and academic purpose will be taken only after due consent from the patients.

Subsequent to this, patients will undergo CT Angiography. The diameter of STA and PAA will be measured on CT Angiography. Branching pattern of STA will also be assessed.

The surgery will be done in a staged manner, utilizing Modified Nagata technique employing Temporoparietal flap based on Superficial Temporal Artery and customized to suit the individual patient. Intra operative proforma including size, shape and location of flap, time taken for temporoparietal flap harvesting and total time of surgery from draping to closure will be filled separately for both stages.

There would be minimum 3 months gap between both stages. Patients will stay admitted in the ENT ward for few days after each stage during which they will be closely observed to look for any complications, and will be subsequently discharged and will be followed up in OPD.

Proforma will be updated for details in the post-op period to look for any complication.
