The role of ostiomeatal complex obstruction in maxillary fungus ball.

Objective: The aim of this study was to clarify the role of ostiomeatal complex obstruction in maxillary fungus ball.

Study Design And Setting: Comparative study in a hospital setting of the mean Lund-Mackay scores for the anterior ethmoid and frontal sinuses of 54 versus 48 patients with maxillary fungus ball versus chronic unilateral rhinosinusitis, respectively.

Results: In cases with partial opacification in the maxillary sinus, the anterior ethmoid and frontal sinuses were diseased in the chronic unilateral rhinosinusitis group but not in the maxillary fungus ball group.

A comparison assessment of videotelescopy for diagnosis of pediatric otitis media with effusion.

Objectives: A correct diagnosis of pediatric otitis media with effusion (OME) is imperative for instituting an appropriate treatment. The aim of this study was to compare the diagnostic efficacies of videotelescopy, pneumatic otoscopy, and tympanometry for detecting the presence or absence of pediatric OME, and thereby, to recommend a standardized procedure for assessing possible OME in the outpatient setting of a referral center.

Study Design: Prospective study.

Angiofibroma of the hypopharynx.

Primary extranasopharyngeal angiofibroma is very rare. To date, approximately 60 cases have been reported in the English literature. Only 1 case was confined to the posterior wall of hypopharynx.

Parosteal osteosarcoma of the mastoid bone following radiotherapy for nasopharyngeal carcinoma.

Radiation-induced tumors subsequent to nasopharyngeal carcinoma are very rare. To date, no post-irradiation parosteal osteosarcoma of the craniofacial bone has been reported in the English literature. In October 2000, a 57-year-old Chinese woman presented 5 years after radiotherapy for nasopharyngeal carcinoma with a 6-month history of a gradually enlarging left postauricular mass.

Malignant fibrous histiocytoma of the maxillary sinus presenting as toothache.

Malignant fibrous histiocytoma (MFH) is a high-grade and aggressive sarcoma. It is relatively rare in the head and neck region. Its diagnosis is based on immunohistochemical stains.

Bacteriology of medically refractory acute otitis media in children: a 9-year retrospective study.

Objective: To identify the causative organisms for medically refractory acute otitis media (AOM) in children, and to recommend the appropriate antibiotics for these patients.

Study Design: Retrospective chart review.

Methods: The medical records for 671 children (1258 ears) undergoing myringotomies between January 1993 and December 2001 were retrospectively reviewed.

Managements of complicated otitic abscess.

The advent of antibiotics has significantly reduced the incidence and associated morbidity of otogenic complications. Its presentation, however, has dramatically changed and appears as a masked condition despite the presence of a potentially fatal complication. Between 1998 and 2001, 3 cases of otitic abscesses, including mastoid subperiosteal abscess, zygomatic abscess, and retropharyngeal abscess, were collected retrospectively.

The contralateral ear in patients with middle ear cholesteatoma after long-term follow-up.

Background: We aimed to develop a strategy for long-term follow-up of the contralateral ear in patients with cholesteatoma and to determine if the patients' age at surgery for cholesteatoma affects the condition of the contralateral ear during this follow-up.

Methods: From May to November 1999, patients followed for previous cholesteatoma surgery were enrolled. The contralateral ears were examined by the senior author (Dr.

Videofiberoptic examination of the pharyngoesophageal segment and esophagus in patients after total laryngectomy.

Background: Posttreatment follow-up in patients with squamous cell carcinoma of the head and neck is critical because of the high risk of recurrence or a new primary tumor. However, in patients who have undergone total laryngectomy, evaluation of the pharyngoesophageal segment (PES) and esophagus is difficult.

Methods: Sixty patients who had undergone total laryngectomy received a videofiberoptic examination of the PES and esophagus at the OPD office during follow-up.

Voice rehabilitation in laryngectomees: comparison of daily-life performance of 4 types of alaryngeal speech.

Background: We compared 4 kinds of alaryngeal speech available in Taiwan in the performance of daily-life tasks. The speech methods included pneumatic device (Taiwan tube), electrolaryngeal speech, esophageal speech, and tracheoesophageal prosthesis.

Methods: Questionnaires covering various communication situations in daily-life tasks as well as subjective feelings about using alaryngeal speech were distributed to members of The Taiwan Laryngectomees' Association and were collected mostly in April 2000 in their annual meeting.

Fibrous dysplasia of the ethmoid sinus.

Although craniofacial bone is the second common site of fibrous dysplasia involvement, it is rarely found in the paranasal sinus. Among fibrous dysplasia of the head and neck, the maxilla and mandible are the most frequent sites to be involved. Fibrous dysplasia becomes dormant in adolescence and early adult life and is more common in female.

Mastoid-obliteration surgery with cartilage for suppurative cholesteatomatous ears.

Background: Autologous cartilage has been widely used as a material for tympanoplasty and mastoid-obliteration surgery. Since it remains vulnerable to an infectious condition, this study aims to evaluate if it can be used for a chronic suppurative cholesteatomatous ear to achieve single-stage tympanoplasty with mastoidectomy and obliteration of the cavity.

Methods: From January 1988 to August 1998, the records of patients with cholesteatoma who received cartilage-obliteration surgery performed by Dr.

Diagnostic methods for otitis media with effusion in children.

Background: Correct diagnosis of otitis media with effusion (OME) in children is imperative for instituting appropriate treatment. This study aims to establish the diagnostic value of pneumatic otoscopy, tympanometry, acoustic reflectometry and videotelescopy by comparing them with myringotomy findings.

Methods: Between November 1999 and July 2001, we conducted a prospective study on diagnosis of OME in children.
