ABSTRACT
Our aim was to investigate the prevalence of Haller cells in a group of patients listed for sinus lifting, and to assess the correlation between postoperative maxillary sinusitis and their presence. A total of 102 patients (150 sides) were evaluated retrospectively on cone-beam computed tomography (CT). The presence and dimensions of Haller cells were noted on the scans. The development of postoperative maxillary sinusitis was recorded. Fisher's exact test was used for statistical evaluation and probabilities of less than 0.05 were considered significant. Maxillary sinusitis developed after sinus lifting in five patients, and Haller cells were found in three of them. However, there was no correlation between the presence of Haller cells and postoperative maxillary sinusitis (p=0.638). The cells were larger in patients with postoperative maxillary sinusitis, and the greater dimensions may be a potential risk factor for developing it after a sinus lift.

The aim of this study was to assess the effect of isolated V-Y plasty on lip lengthening and the treatment of gummy smile. An isolated V-Y plasty was performed on 14 patients with a gummy smile. In each case, measurements of upper lip length and gingival display were recorded from posed-smile photographs taken preoperatively and at 1, 3, and 6 months postoperatively. Gingival display decreased significantly and lip length increased significantly over all intervals investigated. Applying this technique after Le Fort I surgery may be beneficial; however, as with other injection or surgical lip lengthening methods, its stand-alone application should be questioned.

AIMS: Conservative treatment of jaw cysts establishes low surgical complication risk and protects vital anatomical structures such as inferior alveolar nerve, maxillary sinus and permanent tooth germs. Marsupialization and decompression have been widely used in children. The aim of this study was to evaluate the results of the conservative treatment of jaw cysts in five children. MATERIALS AND METHODS: This article presents case series of marsupialization in jaw cysts associated with impacted teeth in five children. A total of nine impacted teeth within the cystic lesions were observed. RESULTS: Complete resolution of all cystic lesions and simultaneous eruption of six impacted teeth within the cyst were managed. The other two teeth were erupted orthodontically and one had to be extracted. CONCLUSIONS: Marsupialization is effective for the treatment of cystic lesions in growing patients as it preserves vital anatomical structures and enables eruption of the impacted teeth within the cyst.

AIM: The aim of the present study was to compare the neurosensory complications related to implants inserted closer than 2 mm to the inferior alveolar canal (IAC) with those inserted further than 2 mm. MATERIALS AND METHODS: A total of 474 implants in 314 patients placed posterior to mental foramen area were evaluated retrospectively on panoramic radiographs. Patients were divided into two groups regarding implant proximity to the IAC (Group 1, distance ≤2 mm, Group 2, distance >2 mm). Postoperative neurosensory complications (pain and paresthesia) were recorded. Chi-square test was used for statistical comparison and P ≤ 0.05 was considered significant. RESULTS: One hundred and fifty-three implants (32.2%) were inserted closer than 2 mm to the IAC whereas 321 implants (67.8%) were inserted further than 2 mm. Three implants which had a distance of 0 mm to the IAC (0.63%) caused paresthesia after surgery. Implant distance to IAC did not show a significant difference regarding pain and paresthesia (P = 0.06 and P = 0.08, respectively). CONCLUSION: When 2 mm is considered as a safety distance, the distance of the implants to the IAC did not yield any statistical difference regarding postoperative neurosensory complications.
