Fat grafting for facial rejuvenation is often followed by significant and unpredictable resorption within the first few months. No one has been able to validate the best technique to ensure long term volumetric retention of fat transfer and results continue to be unpredictable. Fat alone as a filler for facial rejuvenation may not be the best optio...

Minimal blood loss in palatoplasty can be achieved with adrenaline saline hydro dissection, and a good knowledge of key anatomical structures as well as the stubborn areas of static resistance, where dissection is difficult because of fixed tissue planes. With the advent of minimal incision palatoplasty, buttonhole and medial-only incision procedur...

Understanding the key anatomical areas of static resistance due to tight tissue planes makes cleft palate easier, and along with saline hydro dissection, decreases blood loss.

Understanding the surface anatomy markers for the hamulus in palate surgery is often a useful pointer to the position of the hook of hamulus during cleft palate surgery. This innovative idea is of particular use in Veau 1 and 2 where only medial incisions are used. Younger cleft surgeons feel more comfortable when they are able to clearly see palat...

Maxillary deficiency is among the huge culprits in orthodontic patients seeking treatment. Multiple treatment modalities are there to tackle this problem. The most common treatment approaches are rapid maxillary expansion (RME) and miniscrew/surgical assisted rapid palatal expansion (MARPE/SARPE). In this article we reviewed two different approache...

Unilateral cleft lip surgery is part and parcel of every trainee cleft surgeon's armamentarium. As their cleft expertise is founded on solid principles and anthropometric measurements, the chances of error and iatrogenic deformity are significantly lower than that of the untrained surgeon who attempts cleft surgery. In this communication we would l...
