RESUMEN
Sigmoid sinus diverticula are relatively rare but typically cause pulsatile tinnitus (PT) in the involved ear. Occasionally, symptoms produced by blood flowing through the diverticulum are severe enough to necessitate recontouring the sigmoid sinus. Recently, a 59-year-old female was evaluated after years of worsening unilateral PT. CT angiography identified a 5 mm sigmoid sinus diverticulum near the sinodural angle. Given the severity of symptoms, the patient's diverticulum was surgically decompressed and recontoured using hydroxyapatite bone cement.
RESUMEN
CASE DESCRIPTION: A 4-year-old spayed female French Bulldog was referred for treatment of a suspected right-sided nasal angiofibroma associated with a 4-month history of unilateral nasal discharge and stertor. CLINICAL FINDINGS: The dog appeared healthy other than right-sided mucoid debris and decreased airflow through the right naris. The dog was anesthetized, and a large intranasal mass was observed obstructing the right nasal passage and abutting the nasal septum. TREATMENT AND OUTCOME: A lateral rhinotomy was performed, and rigid endoscopes (0° and 30°) were used to examine the right nasal cavity. The mass filled the anterior aspect of the nasal cavity and involved a portion of the nasal turbinates with some erosion. A coblation unit was used to ablate tumor tissue laterally to remove the tumor in piecemeal fashion. Recovery was routine with only minor epistaxis after surgery, and the dog was discharged the next day. Eight months after surgery, follow-up CT revealed right-sided nasal turbinate and conchal atrophy consistent with prior mass ablation. No macroscopic recurrence was detected, and the owners reported only rare, clear rhinorrhea. CLINICAL RELEVANCE: Findings suggested that coblation may be an alternative to radiation therapy for vascular tumors with minimal invasion and low metastatic potential.

OBJECTIVE: Evaluate the effectiveness of remote programming for cochlear implants. STUDY DESIGN: Retrospective review of the cochlear implant performance for patients who had undergone mapping and programming of their cochlear implant via remote connection through the Internet. METHODS: Postoperative Hearing in Noise Test and Consonant/Nucleus/Consonant word scores for 7 patients who had undergone remote mapping and programming of their cochlear implant were compared with the mean scores of 7 patients who had been programmed by the same audiologist over a 12-month period. Times required for remote and direct programming were also compared. The quality of the Internet connection was assessed using standardized measures. Remote programming was performed via a virtual private network with a separate software program used for video and audio linkage. RESULTS: All 7 patients were programmed successfully via remote connectivity. No untoward patient experiences were encountered. No statistically significant differences could be found in comparing postoperative Hearing in Noise Test and Consonant/Nucleus/Consonant word scores for patients who had undergone remote programming versus a similar group of patients who had their cochlear implant programmed directly. Remote programming did not require a significantly longer programming time for the audiologist with these 7 patients. CONCLUSION: Remote programming of a cochlear implant can be performed safely without any deterioration in the quality of the programming. This ability to remotely program cochlear implant patients gives the potential to extend cochlear implantation to underserved areas in the United States and elsewhere.
