The aim of this paper was to describe a modification to an old method to enhance the vermillion in adult cleft patients. We present ten consecutive patients who requested enhancement of the upper lip vermillion. The technique involves a continuous V plasty within the non-visible mucosa to elevate the vermillion.

- Maxillary osteotomy is a surgical procedure performed to correct facial growth issues in patients with cleft lip and palate, but it can lead to velopharyngeal insufficiency, causing hypernasality in speech.* -
- The study examined 20 patients through various speech assessments before and after surgery to identify factors predicting the development of hypernasality.* -
- Significant predictors of hypernasality post-surgery were found to be the closure ratio and the amount of palate contacting the posterior pharyngeal wall, highlighting key areas for monitoring in recovery.*
Article Synopsis
- The study aimed to evaluate how maxillary osteotomy impacts velopharyngeal function in patients with cleft lip and palate (CLP) through various instrumental measures.
- At three time points (pre-surgery, 3 months post-surgery, and 12 months post-surgery), nasalance and velar parameters were assessed using specific tools and methods.
- Results indicated a significant adverse effect on nasalance after maxillary osteotomy and suggested the need for earlier post-surgical evaluations, highlighting that changes in velopharyngeal function appear to be permanent.
Background: Patients with a cleft lip and/or palate may require multiple episodes of orthodontic treatment, e.g. before alveolar bone grafting, upper arch alignment, orthodontic camouflage and in combination with orthognathic surgery.

Design: A retrospective analysis of prospectively collected nonrandomized data.
Interventions: Consecutive participants with a unilateral cleft lip and palate (UCLP) were operated on, at 3 months of age, by the same surgeon.
An Evaluation of Alveolar Bone Grafting in the UK and Ireland.
Cleft Palate Craniofac J

Objective: To determine the main factors influencing the timing of alveolar bone grafting among cleft teams in the UK and Ireland, to assess the types of radiographs used to evaluate bone grafting sites pre- and postoperatively and the views of the profession on orthodontic expansion prior to grafting.
Design: An online survey consisting of 24 questions was compiled and emailed to 53 orthodontists and surgeons in all 12 Cleft Hub Units in the UK and Ireland.
Results: All units in the UK and Ireland responded with 51 responses, 39 complete and 12 partial responses, obtained from cleft surgeons and orthodontists.
There is still no reliable tool to determine the outcome of the repaired unilateral cleft lip (UCL). The aim of this study was therefore to develop an accurate, reliable tool to measure vertical lip height from photographs. The authors measured the vertical height of the cutaneous and vermilion parts of the lip in 72 anterior-posterior view photographs of 17 patients with repairs to a UCL.

Methods: Common orthodontic appliances were studied on 1.5 T scanner using standard spin and gradient echo sequences (based on the American Society for Testing and Materials standard test method) and sequences previously applied for high-resolution anatomical and dynamic real-time imaging during speech.
A case report of a rare finding of supernumerary primary and permanent canines.
J Int Oral Health
April 2014
A supernumerary tooth is a tooth that is additional to the normal series of teeth. These can occur anywhere in the primary or permanent dentition and are most commonly found in the anterior maxilla. Supernumerary canines are rare with little available literature and case reports in this area.

Design: Retrospective, single-blinded, cohort study.
Setting: Study model sets of 40 consecutive, non-syndromic, infants with complete UCLP operated on between 1988 and 1998.
