Takotsubo cardiomyopathy precipitated by maxillofacial surgery and general anesthesia: a case report and review of literature.

PURPOSE: Takotsubo cardiomyopathy (TCM) is a syndrome characterized by a transient episode of heart failure. The specific etiology of this condition is widely speculated. The purpose of this case report and literature review was to investigate the incidence of TCM with regard to general anesthesia, especially those cases involving operative procedures within the realm of oral and maxillofacial surgery. It is intended that the present case serve as a guide for fellow surgeons to identify and manage this syndrome. MATERIALS AND METHODS: The present case was explained and a review of the literature was performed. PubMed was used to search for articles involving surgical procedures under general anesthesia, including oral and maxillofacial surgery. RESULTS: It was determined that TCM rarely occurs in conjunction with surgical procedures under general anesthesia, especially those of the head and neck region. CONCLUSIONS: TCM is an uncommon medical condition with significant morbidity and mortality when managed incorrectly. The occurrence of this syndrome in relation to oral and maxillofacial procedures is also rare, although it is imperative that surgeons be able to recognize and treat this condition appropriately.

Ophthalmic injuries in patients with zygomaticomaxillary complex fractures requiring surgical repair.

PURPOSE: Injuries to the middle third of the face commonly destroy the integrity of the orbital skeleton, and are frequently complicated by injury to the eye, ranging between 2.7% and 90.6% in reported series. This article is a retrospecitve, descriptive case study assessing the spectrum and incidence of ophthalmic involvement in patients presenting with zygomaticomaxillary complex (ZMC) fractures. PATIENTS AND METHODS: Ninety-six patients with ZMC fractures who were surgically treated in 1 academic institution between 1996 and 2006 were assessed pre- and postoperatively by the same oculoplastic surgeon and were included in the study. All patients had a thorough ophthalmologic examination that included assessment of visual acuity, pupillary reactivity, anterior and posterior segment examination, and extraocular motility. In cases of optic neuropathy, automated perimetry was also performed. The variables reviewed included patients' age, gender, mechanism of injury, visual acuity, pupillary reactivity, extraocular motility, presence or absence of diplopia, ocular and orbital findings, and intraorbital hypoesthesia. RESULTS: Gender distribution of the patients was 88% male, with a mean age of 36 years. The most common etiology of trauma was assult (56%), followed by falls (21%). Most patients (66.6%) sustained minor ocular injuries such as subconjuctival hemorrhage, iris sphincter tear, and corneal abrasion. Subconjunctival hemorrhage was the most common minor injury, accounting for 55% of the cases. Major injuries such as ruptured globe and retinal hemorrhage occurred in 10% of the patients. Orbital findings such as restriction of extraocular movement occurred in 15% of cases. Symptomatic diplopia was noted in 16% of the patients and traumatic optic neuropathy occurred in 6%. Diplopia significantly improved in the first 3 postoperative months, dropping from a preoperative incidence of 16% to 2%. CONCLUSION: Comminuted ZMC fractures had been reported to be associated with a signficantly higher incidence of visual sequelae than other forms of midfacial injury. A 10% incidence of major or blinding injuries and a 6% incidence of traumatic optic neuropathy are significant, and warrants a prompt ophthalmologic examination of all patients with ZMC fractures as quickly as possible, and always preoperatively in injuries necessitating surgical repair.

Recurrent double lip: literature review and report of a case.

Double lip is a rare oral anomaly caused by hyperplastic tissue of the labial mucosa that becomes more prominent with tension caused by smiling. This congenital or acquired abnormality can interfere with chewing, speaking, and esthetics. Recognition of double lip and appropriate surgical treatment can reduce these potential problems. The purpose of this article is to review the literature regarding double lip and present an unusual case of recurrence simultaneously involving the upper and lower lips.
