A 30-year-old female patient with a benign tumor in the superficial lobe of the left parotid gland underwent tumor resection via a 5 cm intra-hairline incision, using the da Vinci Xi surgical robot combined with the NIM-Response 3.0 facial nerve monitoring system. During the operation, facial nerve branches were located and protected through facial nerve monitoring, and the robotic arms were used for precise tumor dissection. Postoperatively, the facial nerve function, incision healing, and tumor recurrence were observed. duration of the procedure was 120 minutes, and the tumor（2.0 cm×1.5 cm） was completely resected. Postoperative pathological examination indicated a pleomorphic adenoma. During the 3-month postoperative follow-up, the patient's facial nerve function remained normal, no salivary fistula occurred, the incision was hidden within the hairline, no tumor recurrence was found in the ultrasound reexamination, and the patient was highly satisfied with the appearance. The surgical approach of robot-assisted resection of benign parotid gland tumor via a hairline incision under facial nerve monitoring has significant advantages in facial nerve protection and cosmetic effect, and is suitable for patients with benign parotid gland tumors meeting specific conditions.

Objective: To explore the classification and reconstruction strategy of defects in lateral face region after operation of malignant tumors. Methods: Eighteen cases with the reconstruction of complicated defects after resection of tumors in the region of lateral face from January 2015 to January 2018 in Hunan Cancer Hospital were retrospectively reviewed. There were 14 males and 4 females, aged from 32 to 68 years. According to the presence or absence of bony scaffold, complicated defects were divided into two main categories: soft tissue perforating defects and soft tissue defects combined with bony scaffold defects. All soft tissue perforating defects in 5 cases were repaired with free anterolateral femoral flaps. Among 13 cases with soft tissue plus bony scaffold defects, 3 were repaired with free fibular flaps, 6 with free fibular flaps combined with free anterolateral femoral flaps, and 4 with chimeric deep circumflex iliac artery perforator flaps combined with anterolateral femoral flaps. Results: All flaps survived well. Two patients complicated with fistula in floor of mouth, but the wound healed after dressing change. Transoral feeding was resumed within 2 weeks after surgery in all patients. One year follow-up evaluation showed that 14 cases had symmetrical face and 10 cases had mouth opening more than 3 transverse fingers. After 36-50 months of follow-up, 6 patients died, with an overall 3-year survival rate of 66.7%. Conclusion: The classification of defects with or without bony stent loss is conducive to the overall repair design, the recovery of facial contour stent, the effective fill of dead space and the maintain of residual occlusal relationship. Good reconstruction results require a multi flap combination of osteocutaneous and soft tissue flaps.

OBJECTIVE: To propose and evaluate the clinical effect of midpiece facial nerve dissection through transparotid approach in regional parotidectomy. METHODS: A total of 136 patients with benign parotid tumors were categorized into three groups according to the way of facial nerve dissection: anterograde dissection from main trunk (anterograde, n=70), retrograde dissection from distal branches (retrograde, n=34), and midpiece dissection through transparotid approach (middle dissection, n=32). Surgery duration, facial nerve injury, salivary fistula, earlobe sensation, Frey's syndrome, and aesthetic evaluation were compared. RESULTS: The surgery duration in the middle dissection group was significantly shorter than that in the other two groups. The proportion of salivary fistula was higher in the anterograde group (9 cases, 12.9%; P<0.05) compared with that in the other groups. Postoperative facial nerve injury was similar between the middle dissection (1 case, 3.1%) and anterograde groups (3 cases, 4.3%) with lower injury rate compared with the retrograde group (7 cases, 20.6%). The anterograde group had more cases of hypoesthesia of the earlobe (12 cases, 17.1%; P<0.05) than the other two groups. Aesthetic score was higher in the anterograde and middle dissection groups compared with that in the retrograde group (P<0.05). CONCLUSIONS Midpiece facial nerve dissection is technically feasible and clinically viable in regional parotidectomy.

OBJECTIVE: To investigate the clinical efficacy of a modified paramedian lower lip-submandibular approach for maxillary (subtotal) total resection. METHODS: Eleven patients of maxillary tumors underwent maxillary (subtotal) total resection through the modified paramedian lower lip-submandibular approach. Clinical follow-up visits were conducted to evaluate appearance restoration, facial nerve functional status, parotid gland functional status, and orbital region complication. RESULTS: During the follow-up period of 6-36 months, the appearance of all 11 patients recovered well. All cases presented hidden scars. No facial nerve and parotid duct injury, lower eyelid edema, lower eyelid ectropion, or epiphora in all cases was observed. CONCLUSIONS Applying modified paramedian lower lip-submandibular approach to maxillary (subtotal) total resection effectively reduces incidence of orbital region complications including lower eyelid edema, lower eyelid ectropion, and epiphora, which often occur to traditional approach. The modified approach produces more subtle scars than other methods and should be applied to treatment of maxillary (subtotal) total resection.

PURPOSE: To understand the ophthalmic clinical features and outcomes of facial nerve palsy patients who were referred to an ophthalmic clinic for various conditions like Bell's palsy, trauma, and brain tumor. METHODS: A retrospective study was conducted of 34 eyes from 31 facial nerve palsy patients who visited a clinic between August 2007 and July 2017. The clinical signs, management, and prognosis were analyzed. RESULTS: The average disease period was 51.1 ± 20.6 months, and the average follow-up duration was 24.0 ± 37.5 months. The causes of facial palsy were as follows: Bell's palsy, 13 cases; trauma, six cases; brain tumor, five cases; and cerebrovascular disease, four cases. The clinical signs were as follows: lagophthalmos, 24 eyes; corneal epithelial defect, 20 eyes; conjunctival injection, 19 eyes; ptosis, 15 eyes; and tearing, 12 eyes. Paralytic strabismus was found in seven eyes of patients with another cranial nerve palsy (including the third, fifth, or sixth cranial nerve). Conservative treatments (like ophthalmic ointment or eyelid taping) were conducted along with invasive procedures (like levator resection, tarsorrhaphy, or botulinum neurotoxin type A injection) in 17 eyes (50.0%). Over 60% of the patients with symptomatic improvement were treated using invasive treatment. At the time of last following, signs had improved in 70.8% of patients with lagophthalmos, 90% with corneal epithelium defect, 58.3% with tearing, and 72.7% with ptosis. The rate of improvement for all signs was high in patients suffering from facial nerve palsy without combined cranial nerve palsy. CONCLUSIONS: The ophthalmic clinical features of facial nerve palsy were mainly corneal lesion and eyelid malposition, and their clinical course improved after invasive procedures. When palsy of the third, fifth, or sixty cranial nerve was involved, the prognosis and ophthalmic signs were worse than in cases of simple facial palsy. Understanding these differences will help the ophthalmologist take care of patients with facial nerve palsy.

OBJECTIVES: The purposes of this study were to evaluate the clinical characteristics of temporal bone metastasis (TBM) and to determine whether the characteristics differed according to primary malignancy. METHODS: We retrospectively analyzed data on 20 patients diagnosed with TBM between January 2000 and January 2017. Demographics, the period from diagnosis of primary malignancy to TBM diagnosis, the period from TBM diagnosis to death, the type and staging of primary malignancy, otologic manifestations, and TBM sites were assessed. After the primary malignancies were divided into solid cancers and hematologic malignancies, each parameter was compared between the two groups. RESULTS: The most common primary malignancy with TBM was lung cancer (45%). The most common otologic symptoms and signs were facial palsy (30.5%) and hearing loss (30.5%). The temporal squama (23%) and the facial nerve (20%) were the most commonly involved. Most TBMs occurred late in the disease process after the primary malignancy first metastasized to other organs. Hematologic malignancies metastasized significantly more frequently to the external auditory canal and the middle ear/mastoid compared to solid cancers (P=0.001 and P=0.004, respectively). CONCLUSION: If otologic manifestations such as facial palsy and hearing loss are presented in patients at advanced stages of malignancy, TBM of primary malignancy should be suspected. In addition, hematologic malignancies tend to metastasize to the external auditory canal and the middle ear cleft more commonly than solid cancers do.

Supratentorial extraventricular anaplastic ependymoma (SEAE) in adults is a relatively rare intracranial tumor. Because of the very low prevalence, only a few cases have been reported. According to a recent study, SEAE is associated with a poor prognosis and there is no definite consensus on optimal treatment. We report a case of an adult SEAE patient who had no recurrence until seven years after a gross total resection (GTR) followed by conventional radiotherapy. A 42-year-old male had a persistent mild headache, left facial palsy, dysarthria, and left hemiparesis. Preoperative neuroimaging revealed an anaplastic astrocytoma or supratentorial ependymoma in the right frontal lobe. A GTR was performed, followed by adjuvant radiotherapy. Histologic and immunohistochemical results revealed anaplastic ependymoma. After seven years of initial therapy, a regular follow-up MRI showed a 3-cm-sized partially cystic mass in the same area as the initial tumor. The patient underwent a craniotomy, and a GTR was performed. Histopathologic examination revealed recurrence of the SEAE. External radiotherapy was performed. The patient has been stable without any disease progression or complications for 12 months since the surgery for recurrent SEAE.

Giant cell reparative granuloma (GCRG) is a rare benign bone disease of unknown causes. Trauma is a suspected cause or contributor to the onset of GCRG, of which only a few cases have been reported worldwide. We report a case of temporal bone GCRG in a 4-month-old male newborn, who was born at full term via spontaneous vaginal delivery with recent presentation of right facial palsy. He had a right temporo-occipital craniectomy due to GCRG 1 month earlier. There had been no history of trauma. During the workup of the facial palsy complaint, we identified a lobulated mass in the right temporal bone by computed tomography and magnetic resonance imaging. The mass was mainly in the petrous portion of the temporal bone with extracranial extension through the occipital bone. This was consistent with a GCRG recurrence. The mass was removed via the transcrusal approach, and the final histopathology report confirmed it as recurrent GCRG.
