Minimizing mid-facial growth impairment is one of the treatment goals in cleft lip and palate surgery. As growth of the maxilla extends into young adulthood, long-term evaluation is essential to make a comprehensive assessment of a treatment protocol. There are numerous treatment approaches for cleft lip/palate surgery, and most have the characteristic distinction between either an early or a late cleft palate closure. PRISMA guidelines were applied to explore the quality of the current literature and to identify treatment factors influencing long-term cephalometric outcomes...

Postoperative nausea and vomiting (PONV) is one of the most unpleasant experiences after surgery. It reduces patient satisfaction and also increases hospital costs due to longer hospitalizations. The aim of this prospective study was to determine whether orthognathic surgery is associated with more PONV than less invasive maxillofacial surgery. Three hundred and eight patients aged 8-87 years who underwent maxillofacial surgery were included. The PONV score, based on the Apfel score, was calculated preoperatively...

OBJECTIVE: Oronasal fistula represents a functional problem, as it may result in nasal regurgitation of food and fluids and it also leads to hypernasal speech. Many methods have been proposed for its closure with a high recurrence rate. The aim of this study was to assess the efficacy of closure of hard palate fistula by two layers of mucoperiosteal flaps. METHODS: Eighteen patients with fistula of the hard palate were included. The fistula was repaired by two layers of mucoperiosteal flaps; the first layer was created from the mucoperiosteum surrounding the fistula as bilateral hinge flaps and the second layer was formed of a rotational flap based on the greater palatine artery...

Palatal defect can be repaired by reconstructive surgery and/or a dental prosthesis. We present prosthodontic rehabilitation of two partially edentulous patients, both with surgically induced palatal defect and explains how to achieve the goal for esthetics and phonetics. This also describes the fabrication of a hollow obturator by two piece method, which is simple and may be used as definitive obturator for maximum comfort of the patient. In both the above cases, since the mouth opening is restricted due to surgery, obturator prosthesis is given as two pieces retained with opposite poles of magnet, which facilitates the removal and insertion of the prosthesis...

BACKGROUND: Opportunities for international missions are highly sought after by medical students, residents, and attending plastic surgeons. The educational benefits and ethical considerations of trainees participating in these ventures have been extensively debated. At the time of this writing, many surgical training programs lack the necessary infrastructure or funds to support missions of this sort. Despite the increasing interest, the perceived benefit of international work has not yet been well studied...

BACKGROUND: Hypertrophic olivary degeneration (HOD) is a rare transsynaptic form of degeneration occurring after injury to the dentato-rubro-olivary pathway ("Guillain-Mollaret triangle"). The majority of studies have described HOD resulting from posterior fossa (PF) hemorrhage or infarction. HOD in patients undergoing PF surgery has not been well characterized. These lesions are rare and symptomatic children with HOD are even more uncommon. The purpose of this study was to evaluate HOD that develops after PF operations in children...

BACKGROUND: Avoidance from palatal blood vessel rupture is a major concern during the palatal soft tissue graft surgery. There is no defined chair-side and case-specific palatal blood vessel detection approach to facilitate the harvesting process. The objective of this pilot study is to assess the feasibility of a near-infrared vein visualization system in the screening process of palatal blood vessels. MATERIAL AND METHODS: An extraoral vein visualization device (AccuVein AV400) was applied to a total of 304 hemi-maxilla of 152 individuals by two blind examiners...

Kasper Stokbro, Torben Thygesen
PURPOSE: In orthognathic surgery, the repeatability of 3-dimensional (3D) measurements is limited by the need for manual reidentification of reference points, which can incorporate errors greater than 1 mm for every 4 repeated measurements. This report describes a semiautomatic approach to decrease the manual reidentification error. This study evaluated the repeatability of surgical outcome measurements using the semiautomatic approach. Furthermore, a step-by-step guide is provided to enable researchers and clinicians to perform the 3D analysis by themselves...

OBJECTIVE: Resection of posteriorly located oral squamous cell carcinomas (OSCCs) remains challenging for head and neck surgeons. However, several surgical techniques, such as lip and mandibular splitting, as well as submental "visor drop-down" of intraoral soft tissues, have been proposed for this purpose. Merrick et al. suggested that a pedicled genial drop-down surgical approach should be used to resect dorsally located OSCCs. Our study investigated patient outcomes following this surgical procedure, as no previous study has analyzed long-term follow-up data...
