Facial nerve paralysis due to chronic otitis media: prognosis in restoration of facial function after surgical intervention.

Purpose: Facial paralysis is an uncommon but significant complication of chronic otitis media (COM). Surgical eradication of the disease is the most viable way to overcome facial paralysis therefrom. In an effort to guide treatment of this rare complication, we analyzed the prognosis of facial function after surgical treatment.

Anatomical consideration of the temporal bone as a pathogenesis of Bell's palsy.

Much controversy surrounds the etiology and management of Bell's palsy, and the pathogenetic mechanisms underlying Bell's palsy remain obscure despite the extensive body of relevant research. The pathological condition of Bell's palsy is almost an inflammatory reaction compressing the facial nerve in the fallopian canal, particularly in the narrowest labyrinthine segment, followed by demyelinating neural change. As one of the best method for the visualization of the inflamed facial nerve in the intratemporal segment, temporal bone CT enable us not only to measure the exact length and thickness of individual segments of the facial nerve canal but also to view variable anatomic variations in the intratemporal facial canal.

Effect of topical dexamethasone on sensorineural hearing loss in endotoxin-induced otitis media.

Unlabelled: Sensorineural hearing loss, which is limited to the cochlear basal turn, due to acute or chronic otitis media has been reported in clinical and experimental studies. In the present study, the effect of intratympanic dexamethasone on endotoxin-induced cochlear damage was investigated by measuring the cochlear blood flow and hearing.

Materials And Methods: Ten male Sprague-Dawley rats were inoculated with lipopolysaccharide (LPS), and divided into 2 groups of five rats each.

Cochlear tolerance of Nd:YAG laser myringotomy.

Aim: The objective of this study was to assess whether Nd:YAG laser myringotomy has a negative effect on the cochlea.

Materials And Methods: Ten adult guinea pigs with a normal Preyer's reflex were treated by myringotomy with an Nd:YAG laser (power output 8-10W) under surgical microscopic guidance. Preoperative and immediately postoperative hearing tests were performed using auditory brainstem response.

A case of tympanogenic labyrinthitis complicated by acute otitis media.

Widespread use of antimicrobial drugs in the management of otitis media has significantly reduced the incidence of labyrinthitis nowadays. Cases of tympanogenic labyrinthitis following acute otitis media have rarely been reported in recent literature on otolaryngology. We report an unusual case of tympanogenic labyrinthitis that presented with sudden sensorineural hearing loss (SNHL) following acute otitis media in an adult who had no previous otological complaints.

Penetration of cefprozil to middle ear effusion in children with chronic otitis media with effusion.

Background: Because of chronic otitis media with effusion (COME) demonstrates pathogenic bacteria, treatment with appropriate antibiotic is reasonable.

Objective: We determined the penetration of cefprozil into the middle ear effusion (MEE) in children with COME.

Materials And Methods: 25 patients 2-13 years of age with COME were eligible for study.

Emergence of ciprofloxacin-resistant pseudomonas in pediatric otitis media.

Objective: The widespread use of fluoroquinolone otic drops has resulted in the emergence and subsequent increase of fluoroquinolone resistance, at rates greater than anticipated. To evaluate the patients with recurrent otorrhea that were unresponsive to topical ciprofloxacin.

Methods: Seventeen pediatric patients who were treated with refractory otorrhea between 2000 and 2001 were reviewed retrospectively.
