Background: Antibiotics are known to improve clinical parameters in patients with periodontitis, so they should be capable of enhancing the surgical treatment outcome by improving clinical parameters when given adjunctively following periodontal flap surgery.
Methods: Thirty subjects with moderate to severe periodontitis were randomly divided into three groups: Group I: 10 patients without antibiotic prescription after flap surgery, Group II: 10 patients prescribed with metronidazole 400 mg t.i.d. for 14 days, and Group III: 10 patients prescribed with doxycycline 200 mg o.d. as booster dose followed by successive doses of 100 mg o.d. for 21 days. Plaque index (PI), gingival index (GI), pocket probing depth (PPD), and clinical attachment level (CAL) were recorded at baseline, 2 weeks, and 2 months. The mean values and standard deviation values for each parameter were calculated using analysis of variance. Group comparison was done using paired -and unpaired -tests.
Results: Reduction in PI, GI, PPD, and CAL after 2 weeks and 3 months from baseline in all the three groups was seen; intergroup comparison showed more reduction in PPD and GI and more gain in CAL in Groups II and III after 3 months when compared with Group I. No statistical difference was seen between Groups II and III.
Conclusion: Within the limits of this study, it can be concluded that antibiotic administration as an adjunct to conventional flap surgery helps in improving clinical parameters.

Background: Venous congestion due to superficial venous system dominance (SVD) in deep inferior epigastric perforator (DIEP) flap surgery occurs in approximately 2% of cases, with attendant sequelae and increased cost to healthcare systems. This study aimed to describe the predictive factors for SVD in DIEP flap breast reconstruction based on preoperative computed tomography angiography (CTA) findings.
Methods: All women who required takebacks for additional venous anastomosis to the cephalic vein because of SVD after DIEP flap breast reconstruction between 2015 and 2022 were included.

Background: Virtual surgical planning (VSP) with simple cutting templates could help surgeons preoperatively plan scapula reconstructions in the vertical and horizontal orientations.
Methods: Virtually, eight defects were created in ten healthy mandibles and reconstructed with the subject-specific scapula vertically and horizontally. In the clinical series, 15 single-piece scapula mandible reconstructions planned with in-house VSP and guided with simple templates were compared with 15 freehand reconstructions.

Background: Lip carcinomas account for 23.6% to 30% of tumors affecting the oral cavity. Lip reconstruction aims to achieve a competent oral sphincter with a good cosmetic appearance while avoiding microstomia.

Background: Reconstruction of head and neck defects following tumor excision is one of the most challenging surgeries due to multiple reasons, such as associated cosmetic and functional impairments. The three-dimensional aspect of the defect makes it more difficult. Although in modern settings, microvascular surgery is preferred in many conditions, it requires the presence of resources and expertise.

Background: Exposure of internal mammary vessels in autologous breast reconstruction often requires removal of a rib cartilage segment, which can lead to breast contour deformity. This study evaluated the use of diced cartilage (DC) to counteract substance loss in the microvascular anastomosis area.
Methods: This retrospective, single-center cohort study included all breast reconstructions in which DC was used from October 2021 to June 2023.
