    Cerebrospinal Fluid Leaks From the Lateral Ventricle: A Case Series
    (Wolters Kluwer, 2021-09) Saltagi, Mohamad Z.; Fraser, Amy L.; Alwani, Mohamedkazim M.; Mosier, Kristine M.; Nelson, Rick F.; Otolaryngology -- Head and Neck Surgery, School of Medicine
    OBJECTIVES: Describe the diagnosis and management of lateral skull base (LSB) cerebrospinal fluid (CSF) leaks originating from the lateral ventricle. STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral academic center. PATIENTS: Patients with CSF leaks with direct communication to the lateral ventricle on preoperative imaging. INTERVENTION: Surgical repair via the middle cranial fossa (MCF) approach. MAIN OUTCOME MEASURES: CSF leak patient characteristics (age, sex, body mass index [BMI]) and postoperative course (complications and CSF leak resolution) were collected. RESULTS: Three patients had CSF leaks from the lateral ventricle and all patients demonstrated encephalomalacia of the temporal lobe on preoperative imaging. Encephalomalacia resulted from trauma in one case (age 5) and neurodegeneration in two cases (age 77 and 84). BMI ranged from 16.3 to 26.6 mg/kg2 and follow-up ranged from 4 to 21 months. Two patients presented with preoperative meningitis and all patients had resolution of CSF leaks after MCF repair. With the exception of the higher rate of meningitis, patient presentations did not differ from other spontaneous CSF leaks through middle fossa defects. There were no minor or major postoperative complications. CONCLUSIONS: CSF leaks from the lateral ventricle represent a rare subset of LSB CSF leaks and can occur in non-obese patients secondary to temporal lobe encephalomalacia. The MCF approach allows for repair of the dura and skull base in this cohort of patients with high-flow CSF leaks and loss of brain parenchyma.

    Granular Cell Tumor in a 13-Year-Old Girl
    (Cureus, 2021-11-02) Fraser, Amy L.; Anthony, Benjamin P.; Otolaryngology -- Head and Neck Surgery, School of Medicine
    Granular cell tumors are rare benign soft-tissue lesions that most commonly occur in the head and neck. They usually present in adulthood and are rarely seen in children. Here we present a 13-year-old girl who experienced symptoms of hoarseness of voice for most of her childhood and was unsuccessfully treated for asthma, acid reflux, allergies, and bronchitis before direct visualization revealed what was initially thought to be a vocal cord cyst. Surgical excision and pathology revealed the unexpected diagnosis of a vocal cord granular cell tumor. The patient has had resolution of dysphonia and is undergoing voice therapy.

    Pedicled Cervical Lymphoadipose Tissue for Volume Reconstruction after Superficial Parotidectomy
    (Hindawi, 2021-05-07) Davis, Kyle P.; Fraser, Amy L.; Shay, Elizabeth O.; Sim, Michael W.; Otolaryngology -- Head and Neck Surgery, School of Medicine
    Volume restoration is often required after parotidectomy due to the resultant facial contour deformity. Common procedures include local pedicled flaps, such as the sternocleidomastoid muscle flap, fat grafting, and even autologous free flaps, for more extensive defects. Local pedicled flaps have the advantage of a single surgical site, which spares the patient the added morbidity of a separate fat graft donor site, while simultaneously reducing the operative time. We report two cases of a novel reconstructive option using pedicled level I and II cervical lymphoadipose tissue for volume restoration after superficial parotidectomy. This reconstruction would be useful for patients with benign parotid lesions and inferior parotid defects. In addition, with maintained blood supply to this tissue, it would likely provide sustained bulk over time.
