Lingual nerve paresthesia following third molar surgery: a retrospective clinical study.

Lingual nerve anesthesia, paresthesia, and dysesthesia are possible side effects of third molar extraction. These unwanted complications are frequently disturbing to both the patient and practitioner. The incidence of lingual nerve damage following third molar surgery is more frequent than once thought. Six hundred questionnaires were sent to randomly selected Fellows of the American Association of Oral and Maxillofacial Surgeons in 50 states to determine the parameters surrounding this phenomenon. Of the 452 respondents, 76.05% reported having had patients with lingual anesthesia, dysesthesia, or paresthesia. Of all the reported cases, 18.64% of the cases failed to resolve. Of the reported cases, only three underwent surgical intervention. Because many cases of lingual nerve dysfunction do not resolve, it is important to inform patients that microsurgical nerve repair techniques are available as a modality of treatment following diagnosis. It has also been recommended that if the paresthesia does not resolve within 10 to 12 weeks, then management options including microsurgical nerve reconstruction within a short period of time should be discussed as a plan with the patient.

Intraoral cytomegalovirus lesion and HIV-associated periodontitis in a patient with acquired immunodeficiency syndrome.

Exposure to cytomegalovirus (CMV) is common in persons infected with the human immunodeficiency virus. Autopsy studies have documented the presence of CMV in multiple organs, but CMV is seldom indicated as the causative agent in specific diseases. Few reports have described localized CMV infection in the oral cavity. This may be due to the occult histopathologic appearance during oral mucosal CMV infections and to a lack of awareness of CMV infection as a potential etiologic agent in nonspecific oral ulcerations and other oral disease entities. This report describes an intraoral ulceration with documented presence of a localized CMV infection in association with human immunodeficiency virus-associated periodontitis in a patient with acquired immunodeficiency syndrome. A causative relationship between these two entities, however, cannot be established or excluded.

Pathologic fracture of the mandible associated with simultaneous occurrence of an odontogenic keratocyst and traumatic bone cyst.

A case is presented which involved a pathologic fracture of the mandible associated with a large radiolucent lesion extending from the parasymphysis to the coronoid notch. The osseous defect was found to involve two separate lesions, identified histologically as a traumatic bone cyst in the anterior portion and an odontogenic keratocyst in the posterior aspect. The clinical course and treatment are discussed.

Bilateral lingual nerve anesthesia following mandibular third molar extractions.

Despite the vulnerability of the lingual nerve to damage during third molar surgery, the incidence of permanent nerve anesthesia is relatively low. Bilateral lingual nerve anesthesia has not yet been reported in the literature. A case of bilateral lingual nerve anesthesia following mandibular third molar exodontia is presented, along with possible explanations as to the cause of anesthesia.

Facial bone fractures in children.

From the aforementioned study, the following conclusions can be stated: (1) Patients ranged from 2 to 15 years of age, with no one age group being more susceptible to facial fractures. This fact is contrary to previous findings. (2) No true orbital blow-out fractures were found in patients less thn 7 years of age, primarily because of the lack of maxillary sinus development in that age group. The most rapid development of the maxillary sinus occurs between the ages of 7 to 15 years. (3) In patients from 2 to 7 years of age, fractures occurred at an even ratio of boys and girls. From 8 to 15 years of age there was a boy: girl ratio of about 4.5:1. Of the sixty-seven total patients in the study, boys outnumbered girls by a ratio fo 2.4:1. In order, the condyle, orbit, and mandible were the most common fracture sites observed in the study. This fact is in agreement with past studies. There was no predominant site for any age group or sex. While falls were singly responsible for the greatest number of facial fractures, automobile-related trauma accounted for 47.7 percent of facial fractures in children. In the majority of cases multiple mandibular fractures were of the bilateral condylar type. Hospitalization of patients with automobile-related fractures was approximately 3 days longer than that of patients whose fractures occurred from other causes. More than two thirds of the patients in the study had associated trauma-related medical and dental injuries.

Anterior maxillary corticotomies.

The technique of surgical subapical osteotomy with multiple corticotomies is discussed. A patient with multiple diastemas was presented and concomitant with their surgical orthodontic procedures an adjunctive tongue reduction was performed. The surgery performed on the maxilla was completed in a two-stage operation with that of the tongue completed in the second stage. The tongue revision on the case was performed at the time of the definitive repositioning of the teeth. Patients with anterior maxillary mandibular procedures should be evaluated for the reduction of tongue size concomitant with their surgical orthodontics if a tongue thrust habit, or a markedly encroached floor of the mouth space becomes present. The authors are cognizant of the problems of surgical tongue reduction encountered by many people but have found these, so far, to be inconsequential enough to perform surgical reduction with little hesitation.
