RESUMEN
OBJECTIVES: This study aimed to evaluate the application value of a modified retroauricular hairline incision and a sternocleidomastoid flap with an inferior pedicle in the resection of benign parotid gland tumors. METHODS: Forty-eight patients with benign parotid gland tumors were retrospectively analyzed: 19 cases were included in the experimental group with an improved retroauricular hairline incision and a sternocleidomastoid flap with an inferior pedicle, and 29 cases were assigned in the control group with a modified facelift incision. Operation time, postoperative drainage, postoperative esthetic degree, and incidence of facial nerve paralysis, salivary fistula, and Frey's syndrome were compared. RESULTS: After the esthetic procedure, the average score of the experimental group was higher than that of the control group, and the esthetic effect of the former was better than that of the latter (P<0.05). The incidence of the operation time, facial nerve paralysis, salivary fistula, and Frey's syndrome of both groups had no statistically significant differences (P>0.05). CONCLUSIONS: The modified retroauricular hairline incision and sternocleidomastoid flap with an inferior pedicle can be applied to resect benign parotid gland tumors safely. It shows a better cosmetic effect and does not cause obvious postoperative complications. Therefore, it should be promoted for tumor treatments.

Osteonecrosis of the jaw could occur after intake of bisphosphonate drugs, which are widely used to treat osteoporosis and bone metastasis of malignant tumors. This effect has aroused concern among dentists. In this paper, a case of bisphosphonate-related osteonecrosis caused by implant is reported, and the pathogenesis, diagnosis, prevention, and treatment of bisphosphonate drug-induced osteonecrosis are described through a literature review. The effects of bisphosphonate drug treatment on dental implants are also discussed.

The broken root dislocated into the maxillary sinus is a common complication during the teeth extraction. This article reported broken roots of four patients dislocated into maxillary sinus were removed successfully by endoscope under local anesthesia through windowing in inferior nasal meatus. It is an efficient method, which has less wounds and shorter surgical time.
