BACKGROUND: Passive transcutaneous osseointegrated hearing implant systems have become increasingly popular more recently. The area over the implant is vulnerable due to vibration and pressure from the externally worn sound processor. Good perfusion and neural integrity has the potential to reduce complications. The authors' objective was to determine the ideal surgical exposure to maintain perfusion and neural integrity and decrease surgical time as a result of reduced bleeding. METHODS: The vascular anatomy of the temporal-parietal soft tissue was examined in a total of 50 subjects...

BACKGROUND: Peripheral nerve stimulation has been used for decades to treat chronic pain but has not been used for postoperative analgesia due to multiple limitations, beginning with invasive electrode placement. With the development of small-diameter/gauge leads enabling percutaneous insertion, ultrasound guidance for accurate introduction, and stimulators small enough to be adhered to the skin, neurostimulation may now be provided in a similar manner to continuous peripheral nerve blocks...

Carpal tunnel syndrome, the most common entrapment neuropathy of the upper extremity, is caused by compression of the median nerve as it travels through the carpal tunnel. Classically, patients with the condition experience pain and paresthesias in the distribution of the median nerve, which includes the palmar aspect of the thumb, index and middle fingers, and radial half of the ring finger. Additional clues include positive physical examination findings, such as the flick sign, Phalen maneuver, and median nerve compression test...

Granular cell tumor (GrCT) is a benign nerve sheath tumor. Atypical and malignant variants of GrCT are rare but have been well described. We report a case of multifocal symmetric atypical GrCT in the bilateral hand/wrists of a 15 year old African American female. The initial clinical impression for both masses were favored to be ganglion cysts. Ultrasound findings of both masses revealed hypoechoic soft tissue lesions with some internal echogenicity favoring complex cysts. On excision, both masses were histologically circumscribed, lobulated, and attached to tendon...

BACKGROUND: Post-laparoscopic shoulder pain (PLSP) frequently follows a laparoscopic cholecystectomy. A proposed mechanism for PLSP is the irritation or injury of the phrenic nerve by the CO2 pneumoperitoneum during laparoscopic surgery. Here, we investigated whether a phrenic nerve block (PNB), performed under ultrasound guidance, could reduce the incidence and severity of PLSP after laparoscopic cholecystectomy. METHOD: Sixty patients were randomized into two groups, with one group receiving PNB with 4 ml (30 mg) of 0...
