Evaluation of an oral mandibular advancement titration appliance.

OBJECTIVES: To determine whether a manually adjustable oral mandibular advancement titration appliance (EMA-T) predicts successful long-term treatment with an oral mandibular advancement appliance (MAA). STUDY DESIGN: At an academic medical center, 21 adults with obstructive sleep apnea (AHI > 10 events/hr) performed baseline, titration, and MAA (Klearway) polysomnograms. During the titration polysomnogram with EMA-T, the mandible was advanced until apneas and hypopneas were eliminated or maximum tolerable advancement was reached. Participants then used the MAA at home and, once the mandible was advanced to the amount determined during the titration polysomnogram, a polysomnogram with MAA was performed. RESULTS: Mean AHI at baseline was 33.5 +/- 18.3 (SD) events/hr. During the titration polysomnogram, 9 subjects achieved an AHI < 10 and at least a 50% reduction in AHI. None of the subjects met these criteria on the MAA polysomnogram. CONCLUSIONS: EMA-T lowered the AHI to efficacious levels in 43% of patients but this acute response did not predict the efficacy of long-term MAA treatment.

Genioplasty.

Genioplasty has been a useful and frequently employed technique in the aesthetic facial surgeon's armamentarium. However, as the prevalence of obstructive sleep apnea becomes more apparent and its diagnosis more frequent, genioplasty has also evolved to a commonly performed procedure for reconstruction of the upper airway. This article discusses patient evaluation and surgical techniques used in aesthetic and functional surgery of the chin. Because these topics have been discussed extensively in the literature, this will serve as a synopsis of current techniques.

Cheilitis glandularis: an unusual histopathologic presentation.

Cheilitis glandularis (CG) is an uncommon disease that usually affects the lower lip of adults. It is characterized by enlargement and eversion of the lip in association with excretory duct dilatation. The presence of minor salivary gland hyperplasia is controversial. Three types of CG have been described in the literature; the classification is based on the common clinical and histopathologic findings (ie, simple, superficial, and deep). This report is of an unusual case of CG simplex for which the initial histopathologic diagnosis was papillary cystadenoma, a neoplastic process. The lesion was completely excised, and final microscopic review of a larger specimen revealed chronic sclerosing sialadenitis, dilated salivary secretory ducts with oncocytic change and periductal inflammation, and foci of adenomatous hyperplasia consisting of enlarged ducts exhibiting squamous epithelial metaplasia and hyperplasia with papillary architecture. The latter proliferative pattern is an unusual finding in what is otherwise clinically diagnosed as CG.

Extensive pneumatization of the temporal bone and articular eminence: an incidental finding in a patient with facial pain. Case report and review of literature.

A 53-year-old Caucasian female presented to the Oral Medicine Department at the hospital of the University of Pennsylvania for consultation regarding facial pain. A panoramic radiograph revealed multilocular radiolucencies in the right articular eminence. A CT scan was then performed, and the radiolucencies were determined to be pneumatization of the articular eminence.

Subcutaneous cervicofacial emphysema and pneumo-mediastinum: a rare complication after a crown preparation.

Subcutaneous cervicofacial emphysema and pneumo-mediastinum are relatively rare complications from different dental procedures (including oral surgery and restorative treatment). Many cases go unrecognized or are misdiagnosed. While the majority of cases resolve spontaneously, some can lead to life-threatening complications that require emergency intervention. This article presents a case report of subcutaneous and mediastinal emphysema following a routine restorative dental procedure. The differential diagnosis and management of this condition is discussed.

Extranodal marginal zone lymphoma: a case report and review of the literature.

The World Health Organization (WHO) defines extranodal marginal zone lymphoma (MZL) as an indolent B-cell lymphoma. This disease involves a heterogeneous group of B-cell tumors that occurs primarily within the lymph nodes, spleen, or extranodal tissues. Initial MZL treatment consists of chemotherapy and/or radiotherapy and is associated with a high survival rate when detected early. This article highlights an unusual case of extranodal MZL in the parotid area.
