Abstract:
The most common causes of parotid duct lesions are injuries with sharp instruments. Late alterations after such lesions lead to esthetic defects and complicates the treatment. This case report presents an alternative surgical technique for late reparation of the parotid duct. A 31-year-old male patient was admitted with a history of physical aggression by a glass bottle, resulting in cutting injuries in face and drainage of extraoral transparent fluid from the buccinatory region lesion Antibiotic therapy was initiated immediately, and the surgery was performed nine days after the incident. The repair of the parotid duct lesion was achieved adapting a venous catheter that was passed through the distal portion of the duct from the oral orifice. The proximal segment of the duct was cannulated, the lacerated ends of the duct were approximated on the device and sutured with prolipopylene thread. At the 14-day post-operative return, the saliva was draining through the catheter, and then it was removed. Patients with cutaneous lesions in the buccinatory region require a thorough examination to identify injuries to the parotid duct. The surgical treatment using the presented alternative surgical technique was an effective and cheaper option when compared to other alternatives and showed no complications.

Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
