Objective: To describe the technique of robotic buccal mucosa graft ureteroplasty as a minimally invasive alternative method of ureteral reconstruction for proximal or multifocal ureteral strictures not amenable to primary anastomosis.
Methods: Between October 2013 and May 2014, we performed robotic-assisted ureteral reconstruction using buccal mucosa grafts in four patients (mean age 41.5, range 23-67). The indication for surgery was a proximal or multifocal stricture not amenable to ureteroureterostomy or ureteropyelostomy. Buccal mucosa grafts were harvested to be the length of the strictured segment and 1 cm in width and placed in the ureter as an anterior or posterior onlay. Follow up was performed with diuretic renogram at least 3 months postoperatively and renal ultrasound as well as clinical assessment of symptoms.
Results: All 4 patients underwent successful robotic-assisted reconstruction of the ureter using buccal mucosa graft. There were no intraoperative complications. At a median follow up of 15.5 months (range 10.7-18.6), there has been 100% success.
Conclusion: Robotic buccal mucosa graft ureteroplasty is a feasible option for reconstruction of proximal or multifocal ureteral strictures that are not amenable to primary anastomosis and it avoids the morbidity of alternative procedures.

Purpose: Oral squamous cell carcinoma is one of the most common types of cancer in the head and neck. Squamous cell carcinoma of the buccal mucosa is an important part of it. The traditional surgical method leads to great injury and is accompanied by unacceptable scars.
Statement Of The Problem: Squamous cell carcinomas (SCCs) and premalignant disorders such as leukoplakia are common oral cavity lesions. Although these lesions are epithelial in nature, they are also associated with juxta-epithelial chronic inflammation. Mast cells play a significant role in inflammation initiation and propagation.
As the supply source for gingival grafts, the palatal tissue possesses marked regenerative ability after repeated wounding over the buccal attached gingiva and skin. However, the intrinsic mechanisms are poorly understood. Schwann cells reportedly participate in wound repair of many tissues.
Background: Chronic tobacco use, in any form, induces significant cellular alterations in the oral mucosa. This study investigates four distinct cytomorphological changes in oral mucosal cells among smokeless tobacco users, examining their association across different genders and age groups.
Materials And Methods: This cross-sectional study involved collecting mucosal samples from smokeless tobacco (naswar/snuff) users through consecutive sampling.
Candida albicans is an opportunistic fungal pathogen. It's a dimorphic fungus with hyphal form that can penetrate and proliferate the oral mucosa. Occlusal guard materials come into direct contact with the oral mucosa and saliva when worn for extended periods, the occlusal guard acts as a reservoir for C.
