Patient: Male, 38-year-old Final Diagnosis: Parotid sialolithiasis Symptoms: Painful • swelling Medication: — Clinical Procedure: — Specialty: Surgery Objective: Unusual setting of medical care Background: At present, promptly diagnosing sialolithiasis is easy with the assistance of various noninvasive diagnostic procedures. However, the treatment of parotid sialolithiasis remains inadequate. An immense challenge for oral maxillofacial practitioners is the treatment of large radiolucent stones, especially of those that are located in a hard-to-approach positions in the salivary ducts. This case report aims to propose the protocol of a new technique to improve the management of parotid salivary stones. In 2017, our hospital was the first medical center in Vietnam to implement this technique in the treatment of parotid sialolithiasis. Case Report: A 38-year-old man was diagnosed with parotid sialolithiasis based on ultrasound and computed tomography (CT) scanning results. He underwent ultrasound-guided sialendoscopy with holmium: yttrium aluminum garnet (YAG) laser lithotripsy. The stone was large (22×12 mm) and in an unfavorable position. A narrow strip of fibrous tissue in front of the stone was also noted. However, 1 week after surgery the patient had local swelling of the parotid gland and no manifestation of inflammation, facial paralysis, or obstructed saliva through the drainage ducts. The patient was examined for clinical symptoms and glandular ultrasound at 3 months and 6 months after the procedure. The follow-up examination results showed normal parotid gland function, no complications or recurrence of stones, and no narrowing of the gland duct. Conclusions: Ultrasound-guided sialendoscopy with holmium: YAG laser is safe and effective for treating parotid salivary gland stones.

The management of soft tissue injury after complex facial trаumа poses unique chаllenges to the plаstic surgeon, given the speciаlized nаture of fаciаl tissue аnd the аesthetic importаnce of the fаce. We report 8 cаses with wide-spreаd soft-tissue defects due to complex fаciаl trаumа who presented аt Odonto-stomаtology center-Hue centrаl hospitаl during the yeаr 2018. Of these cаses were surgicаlly mаnаged by fixаtion аnd fаciаl reconstruction аt Odonto-stomаtology center-Hue centrаl hospitаl; аnd they were very well recovery in function аnd аesthetics. The generаl principles of trаumа mаnаgement аnd wound cаre аre аpplied in аll cаses. The mаnаgement of severe injuries to the fаce is discussed in relаtion to the locаtion аnd the mechаnism of injury.

Background: Salivary gland tumors are the most complex and diverse of any organ in the body. Surgery is the mainstay of treatment for salivary gland tumor. Assessing the results of parotid gland tumor treatment is the aim of the study. Objective: To evaluate the results of parotid gland tumor surgery. Materials and Methods: 31 patients with parotid gland tumor who were examined at Hue University of Medicine and Pharmacy Hospital from June 2019 to June 2020 were recorded about clinical, paraclinical and evaluated results at 1 week, 1 month and 3 months after surgery. Results: Histopathological study of parotid salivary gland tumors: pleomorphic adenoma (64.5%), warthin tumour (32.3%), oncocytoma (3.2%). After parotid surgery, cervicofacial branches being the most commonly affected (29%). The most common complication was numbness around the earlope (77.4%), facial paralysis (41.9%), hemorrhage (29.1%), seroma (3.2%) and salivary fistula (3.2%). Conclusion: After performing parotid surgery, facial nerve injury was temporary Key words: Parotid gland, parotidectomy, facial paralysis

Objectives: Congenital cleft lip/palate is most common deformity of the face. Primary plastic surgery for rehabilitation and aesthetics is the need of the patients and family of patients, however, there are many secondary deformities of lip and nose post-surgery. Therefore, assessment of secondary cleft lip/nasal deformities is performed for planning of surgical repair. Method: 46 patient with unilateral cleft lip/palate, were operated with different techniques, are examinated post-surgery at department of Maxillofacial surgery, Hue University of Medicine and Pharmacy Hospital and Centre of Odonto-Stomatology, Hue Central Hospital. These patients were assessed according to the postoperative results of Motier score (1997) including of red lip, white lip, scars, and nose. Results: V notch and defect on the shift line are the most common deformities on red lip (52.2%). 34.8% patient have short white lip on cleft side. Straight and prominent scars is 52.2%. The most common deformities of nose are septal deviation (78.3%), narrow sill (52.2%), defect of the upper part of the nostril rim (78.3%) and low position of ala (47.8%). Conclusion: secondary cleft lip/nasal deformities is unavoidable. It is necessary to have a plan for surgical repair of these deformities. Key words: Unilateral cleft lip/palate, Secondary cleft lip/nasal deformities
