Novel Custom Maxillary Disimpaction Splint.

LeFort I, II, and III osteotomies are commonly used in complex craniofacial reconstruction. Patients requiring these procedures typically have a craniofacial cleft, other congenital craniofacial deformities, or severe facial trauma. Both the cleft and traumatized palate have poor bony support, which leads to possible complications when the disimpaction forceps are used during the downfracture of the maxilla. Such potential complications include trauma or formation of a fistula of the palatal, oral, or nasal mucosa; trauma to adjacent teeth; and fracture of the palate and alveolar bone. To help prevent these complications, we developed a custom disimpaction splint. The splint is designed to cover the palate and occlusal surfaces to increase retention and minimize splint movement during the maxillary downfracture portion of the surgical procedure. The base of the splint is fabricated from a two-layered biocryl material, and the palatal area is built with soft-cushion rebase material. This allows for a stable grip of the disimpaction forceps blades and provides protective coverage of the cleft, traumatized palate, or alveolar bone graft site during the downfracture. The custom maxillary disimpaction splint has been routinely used in our clinic from September 2019 to the present for LeFort osteotomies in patients with a compromised primary palate. No surgical complications related to the maxillary downfracture have been noted during this period of time. We conclude that the routine use of a custom maxillary disimpaction splint can result in improved outcomes and decreased complications of LeFort osteotomy procedures in patients with cleft and traumatized palate.

A Simple Surgical Solution for Functional Improvement of Deforming Vascular Malformations with Lip Involvement.

The management of large, deforming facial arteriovenous malformations (AVMs) can be a daunting clinical challenge for patients and surgeons. Many patients delay treatment due to fear of surgical intervention and concern for unfavorable cosmetic outcomes. Delaying treatment can lead to soft-tissue hypertrophy. Occasionally, facial AVMs can also present with lip involvement, necessitating surgical intervention. A major potential issue regarding AVMs managed with surgical excision is excessive bleeding due to the enlarged dermal vascular plexus. Here, we present a simple surgical technique used to manage deforming AVMs involving the lips. A 32-year-old man with Sturge-Weber syndrome and a 72-year-old man with AVMs of the left face presented to clinic for management. The malformations involved the lips in both patients. Both patients had constant drooling and difficulty eating and talking, in addition to aesthetic concerns. They both underwent surgical excision of the redundant tissue with minimal undermining, advancement flaps, and layered closure. Minimal undermining allowed successful removal of the AVMs and redundant tissue without excessive blood loss and allowed healing without complications. Both patients had significant improvement in eating and talking without drooling. Aesthetically, satisfactory outcomes were maintained at 1-year follow-up appointments. Removal of AVMs while minimizing blood loss can be a challenging endeavor. Here, we have presented a successful, effective technique for restoring both form and function in patients with AVMs involving the lips, with good long-term results.
