These data are consistent with the notion that long-term electrical stimulation may facilitate partial reinnervation in patients with chronic facial paresis/paralysis. Additionally, residual clinical impairments are likely to improve even if motor recovery is not evident.

In this study, the computed tomography scans of 100 patients with chronic hyperplastic rhinosinusitis were reviewed to establish a clinical staging system. Fourteen percent of the patients were classified as Stage I (single-focus disease); 36% as Stage II (multifocal disease responsive to conservative therapy); 32% as Stage III (diffuse disease partially responsive to medication); and 16% as Stage IV (diffuse disease associated with bony changes and poorly responsive to conservative treatment). The incidence of recurrent or persistent disease ranged from 13% for Stage II to 30% for Stage IV. Stage I and III patients had 13% and 18% recurrence rates, respectively. Computed tomography staging is shown to be useful in outlining operative strategies and is a reliable prognosticator of the disease process.

The most devastating sequelae of the facial nerve paralysis is the loss of eye lid function. The inability to blink, lubricate and protect the globe can lead to exposure keratitis, corneal abrasion and even the loss of vision. Eyelid closure is approximately 85% upper eyelid and 15% lower eyelid. In order to ensure adequate protection of the globe, deficiencies of both eyelids must be addressed. We report our experience with 20 patients with eyelid paralysis. Upper lid reanimation was performed by the placement of gold lid weights on the tarsal plate. Lower lid reanimation procedures included lateral canthopexy and horizontal lid shortening. A discussion of the above-mentioned procedures, the timing of the procedures and a critical analysis of results will be included. A comprehensive approach to the management of the paralyzed eye will be presented.

Recently, a laser based on a thulium-holmium-chromium (THC) doped Yttrium-aluminum-garnet (YAG) rod has been developed that produces light of 2.15 microns wavelength and can be transmitted through a low OH- silica fiberoptic cable. This wavelength falls on one of the peaks of the energy absorption spectrum of water. Thus, the THC:YAG laser eliminates the disadvantage of a cumbersome delivery system found in the CO2 laser while still providing precise cutting and minimal tissue injury inherent in lasers emitting light absorbed by water. We evaluated the soft tissue effects of this laser on canine vocal cords. Ablative lesions were produced by the THC:YAG laser and histologically examined on postoperative days 1, 7, and 28. Results indicate that the depth of tissue penetration is easily controlled and the healing response to tissue injury is comparable to that of the CO2 laser. The THC:YAG laser should prove to be a superior laser for use in otorhinolaryngology, especially when adapted to a flexible endoscope.
