Performing surgery in the oral cavity is difficult because of the limited view of the surgical field. Intraoral surgery for infantile oral disorders, such as cleft palate, is even more challenging. Endoscopy provides a minimally invasive approach and clear surgical view in surgeries with a constrained field of view. To date, very few reports have described endoscope-assisted palate surgery for children with cleft palate. At the authors’ institution, endoscopes have been used in primary palatoplasty using the double-opposing Z-plasty technique. A novel endoscope-assisted procedure is described herein, in which a dissection around the greater palatine neurovascular bundle is used to obtain tension-free closure of the palatal cleft. With this technique, it was possible to minimize the application of additional von Langenbeck-type relaxation incisions, which were previously introduced in most of our cases; the relaxation incision was successfully circumvented in 42.3% of cases. This led to lesser surgical interference, which possibly resulted in favourable palatal development. It was also found that the endoscopic procedure did not increase the operation time or blood loss when compared to those patients who underwent the non-endoscopic procedure. It is concluded that endoscopic guidance is quite useful in primary palatoplasty procedures with a constricted surgical view.
