Introduction: The lesions of the salivary ducts may be idiopathic, post- traumatic, or iatrogenic and lead to sialocele formation with persistent painful facial swelling or cutaneous fistula formation. No consensus on treatment of this condition exists: the options of treatment include needle aspiration, pressure dressings, antisialogogue therapy, radiotherapy, botulinum toxin and surgical approaches as duct repair, diversion, ligation, different drainage systems and even parotidectomy/submaxilectomy. The management and special features of iatrogenic salivary duct injury in patients with oral cancer who underwent head and neck reconstructive surgery has not been described yet. Material and Methods: We present four cases of iatrogenic lesions of salivary ducts and its management in patients with oral cancer. Conclusions: The iatrogenic lesions of salivary ducts are to be taken into account in patients with oral cancer as the distal ends of salivary ducts could be involved in the margins of surgical resection. Different options of treatment of this complication are described. Key words:Sialocele, oral cancer, salivary duct.

Osteopetrosis (OP) is a rare metabolic bone disease characterized by a generalized increase in skeletal mass. The disease is characterized by increased susceptibility to develop osteomyelitis of the jaws. We report a case of clinical and radiological progression of bimaxillary osteomyelitis in a patient with autosomal dominant OP. The patient presented non simultaneous osteomyelitis in both upper and lower jaws with time interval of 10 years. The osteomyelitis of maxilla resulted in oroantral fistula formation and required surgical closure with Bichat fat pad flap. The mandibular osteomyelitis resulted in sequestra formation and pathological fracture and required multiple debridement procedures. Both maxillary and mandibular osteomyelitic foci were persistent and healing required more than 2 years. The case confirms the possibility of development of non simultaneous bimaxillary osteomyelitis in patients with OP. The case enhances the need of close follow- up and preventive measures in patients with OP.
