Mandible fracture repair: specific indications for newer techniques.

Mandible fracture repair is commonly undertaken by otolaryngologists. Although the essential principles of reduction and immobilization are undisputed, the approach used to obtain these goals varies considerably. We performed a critical evaluation of all mandible fractures treated at the Santa Clara Valley Medical Center by the otolaryngology service between January 1988 and February 1992, with the purpose of better defining the indications for plate fixation and for the use of more traditional techniques. One hundred eighty-three fractures in 112 patients were evaluable. Thirty-six (32.1%) of these patients had at least one plate placed (group A); 39 (34.8%) underwent an open procedure, with interosseous wire fixation (group B); and 37 (33.0%) were treated with closed techniques (group C). The severity of fracture (indexed by comminution, presence of infection, teeth in the fracture line, interval to repair, and whether the fracture was open or closed) was similar in plated and nonplated mandibles. Mean (+/- standard deviation) operative times for the three groups were 3.2 +/- 1.6 hours for group A, 3.0 +/- 0.9 hours for group B, and 1.4 +/- 0.5 hours for group C. The number of follow-up visits required was not statistically different (group A, 5.6 +/- 3.8 visits; group B, 5.2 +/- 2.5 visits; and group C, 5.3 +/- 2.0 visits). The overall incidence of major complications was 14.3% (16 of 112), including 11 of 36 (30.6%) in group A, 4 of 39 (10.3%) in group B, and 1 of 37 (2.7%) in group C.(ABSTRACT TRUNCATED AT 250 WORDS)

Facial paralysis rehabilitation: retraining selective muscle control.

Traumatic facial paralysis can be improved with surgical techniques but alone will not restore full function. EMG sensory (bio) feedback can, however, facilitate rehabilitation. Four cases are described using a combined treatment technique of EMG, behavioural modification and specific action exercises. Retraining of eyelid control was also accomplished. Standardized evaluation methods are described. All four patients showed improvement, despite the failure of traditional retraining methods.

A method for temporary reconstitution of the cervical esophagus.

A simple method of temporary reconstitution of the cervical esophagus in major head and neck surgery is detailed in a case report. Accompanying diagrams illustrate the mechanics of inserting a number 26 nasopharyngeal airway from the hypopharynx to the esophagus. This arrangement simplifies the management of oral secretions until permanent reconstruction of the cervical esophagus can be accomplished.

Glomus tympanicum--excision by radical mastoidectomy exposure with autograft reconstruction.

Wide surgical exposure, total tumor removal and anatomic and functional reconstruction are the goals of tumor management. These goals are met by radical mastoidectomy exposure for the removal of glomus tympanicum tumors and reconstruction by autograft replacement of the posterior osseous canal, and if the tympanic membrane, malleus and incus are removed for tumor exposure, autograft replacement may also be accomplished. The history, physical findings, X-rays and details of surgical management of two patients with glomus tympanicum are reviewed. Wide removal of the posterior osseous canal, just lateral to the VIIth nerve with total replacement of this segment gives excellent exposure of the middle ear space and affords total reconstruction of the posterior osseous canal.

Long-term stenting in the treatment of subglottic stenosis.

Long-term stenting (3 to 12 months) with silicone rubber stents was found successful in 12 of 14 cases (86%) with severe subglottic stenosis. A new silicone rubber stent is described that is suitable for long-term stenting in infants or adults.
