Evolution of surgical modalities in the management of rhinophyma: our experience

Rhinophyma is a progressive disease of the nose, which is characterised by skin thickening and sebaceous hyperplasia. Patients with rhinophyma are often stigmatised due to worsening disfigurement of their nose. This can also result in functional impairment such as reduced nasal patency. Severe cases of rhinophyma are best managed with varied surgical interventions, as there is no clear 'gold standard' treatment that has been described. We present our experiences in the management of rhinophyma and the evolution of treatment modalities that have been employed over a nine-year period.

The role of platelet count, mean platelet volume, and the mean platelet volume/platelet count ratio in predicting postoperative vomiting in children after deep sedation

Objectives:

To determine the role of hemogram parameters such as platelet count (PLT), mean platelet volume (MPV), and the MPV/PLT ratio in predicting the risk of postoperative vomiting (POV) in children after tooth extraction under deep sedation.

Methods:

A total of 100 American Society of Anesthesiology Classification I and II pediatric patients who underwent tooth extraction procedures under a standard anesthetic method were included in the study between 2012 and 2014. The study took place at the Faculty of Dentistry, Department of Oral and Maxillofacial Surgery, Erciyes University, Erciyes, Turkey Fifty patients without POV (group 1) and 50 patients with POV (group 2) were retrospectively selected randomly from the records of 885 consecutive patients. Age, gender, duration of the operation, and preoperative hemogram findings were recorded.

Results:

There was a statistically significant difference between the 2 groups in terms of MPV (p<0.001), PLT (p=0.006), and MPV/PLT (p<0.001) ratio. Mean platelet volume and MPV/PLT ratio were higher in group 2, whereas PLT was higher in group 1.

Conclusion:

The PLT count, MPV, and MPV/PLT ratio may be used to predict POV in children.

Oral leukoplakia associated with amalgam restorations

The World Health Organization has defined oral leukoplakia (OL) as "a white patch or plaque of the oral mucosa that cannot be characterized clinically or pathologically as any other disease". A 21-year-old male with OL presented with a bilateral burning sensation in the buccal mucosa. The patient had amalgam restorations, and an epicutaneous patch test indicated a positive response to amalgam. The amalgam restorations were therefore removed and the cavities were refilled with a composite resin restorative material. During 5 years of follow-up, there was no recurrence of the oral lesions. This case illustrates that amalgam fillings may cause OL lesions. (J Oral Sci 58, 445-448, 2016).

Are there any differences in mandibular morphology of patients with bisphosphonate-related osteonecrosis of jaws?: a case-control study

OBJECTIVES:

The aim of this study was to compare the morphological differences in the mandible between patients with bisphosphonate-related osteonecrosis of the jaw (BRONJ) and healthy individuals and to detect the correlation between these parameters on panoramic radiography and CBCT.

METHODS:

The CBCT and panoramic images of patients with BRONJ (n = 32) and control groups (n = 32) were included in the study. All the comparisons were analyzed between the osteonecrosed and healthy sides of patients with BRONJ and control group. The panoramic radiographs were used to measure the values of the condyle angle, gonial angle, antegonial angle, antegonial depth, condylar height and ramal height. The mandibular cortical index (MCI) and bone quality index (BQI) were also examined on cross-sectional scans of CBCT images.

RESULTS:

There were significant differences in the MCI (p = 0.014) and BQI (p = 0.021) between the left and right side of the BRONJ group and also between the osteonecrosed side of the BRONJ and control group (p < 0.0001). No significant difference was found in other comparisons.

CONCLUSIONS:

The outcomes of the present study indicate that bisphosphonates influenced some internal morphological changes in the mandible. These changes may be a reason of BRONJ. But, these changes are not reflective of the measured values obtained using panoramic radiographs on the external morphology of the mandible.
