The aims of this study were to find out whether scoring in a rose-trellis pattern improved the stretch of mucoperiosteal flaps more than conventional scoring in the horizontal plane, and to consider its application in the closure of oroantral communications. Sixteen sections of cadaveric porcine buccal mucoperiosteum were removed from the molar region of the maxilla and mandible. A three-sided flap was raised in the subperiosteal plane, excised, and pinned to a cork board with the periosteal side facing upwards. Eight samples were scored in the horizontal plane (control) using lines perpendicular to the line of simulated advancement, and eight in a rose-trellis or criss-cross pattern. Scoring using a rose-trellis pattern yielded a mean increase in stretch of 24.3% (p = 0.0003) when compared with the conventional method. Buccal advancement flaps are widely used to close oroantral communications, and scoring of the mucoperiosteum facilitates the stretching of the tissue over the defect. To be successful, defects should be fully closed to prevent contamination, and closure should be tension-free. In this study, scoring in a rose-trellis pattern increased the stretch of the tissue sample more than scoring in the horizontal plane. The rose-trellis technique therefore could aid the effective closure of oroantral communications.

At Queens Medical Centre, Nottingham, alveolar bone grafts (ABG) for patients with cleft lip and palate (CLP) were performed by two surgeons following the same surgical protocol, but with different postoperative iliac crest donor site analgesia: surgeon A used a donor site bolus of levobupivacaine, whilst surgeon B used a donor site epidural catheter (EC) infusing levobupivacaine. A healthcare evaluation was conducted in two phases to establish the effectiveness of analgesia for CLP patients undergoing ABGs. Data were collected prospectively in 2016 and 2018. Cleft patients postoperative to ABG were included. Outcome measures were pain scores at 2, 4, 6, 12, and 24 hours, time to mobilization, and time to food intake. Mean pain scores at the first evaluation were1 out of 10 for all time points, except 24 hours (score 2.0 for bolus, 1.8 for EC). There was no statistically significant difference between the groups for any of the outcomes measured. As EC conferred no advantage, surgeon B changed to bolus administration and a second evaluation was performed. The mean pain score for the second evaluation was 1.7 and higher pain scores were more common with lower doses of levobupivacaine. The data suggest that bolus injection can produce safe, effective pain control provided an adequate dose is given.

Syphilis is an infectious disease caused by the anaerobic spirochaete Treponema pallidum. Syphilis is known to present with oral manifestations, namely transient ulcers in its primary form, snail-track ulcers in the secondary form and gumma formation in its tertiary form. The patient was presented to the oral and maxillofacial clinic with persistent oral ulceration in the left buccal mucosa, with rolled margins and rapid onset cervical lymphadenopathy therefore mimicking the appearance of oral squamous cell carcinoma. Biopsies of the oral ulceration and of the lymph nodes revealed no malignancy, but features consistent with an infectious process. This case report highlights the diagnostic challenges with the diagnosis of oral syphilis. It also discusses the laboratory tests used to finalise a diagnosis of syphilis, and aims to raise awareness of potential differential diagnosis.
