Cystic lesions of the jaws - a clinicopathological study of 322 cases and review of the literature.

Three hundred and twenty-two patients (192 male and 130 female) with cystic lesions of the jaw were successfully diagnosed and treated. One hundred and fifty-five (48%) were radicular cysts, 80 (25%) were dentigerous cysts, 23 (7%) were odontogenic keratocyst (=keratocystic odontogenic tumor), 19 (6%) were eruption cysts, 16 (5%) were traumatic bone cysts, and 29 (9%) were non-odontogenic cysts. There were 95 in the pediatric age group (1 month to 16 years) and 227 in the adult age group (17 years and older). Male to female ratio was 1 in the pediatric age group and 1.7 in the adult age group. The treatment modalities were: marsupialization, enucleation, enucleation with bone grafting, or resection. The distribution and characteristics of jaw cysts in children are different from those in adults. In children there is a relatively high rate of developmental cysts, whereas in adults the inflammatory cysts are more common. Following enucleation of a cystic jaw lesion, the entire surgical specimen and not only a biopsy specimen, should be examined histopathologically to prevent any possibility of an intramural squamous cell carcinoma that may be overlooked. The differences in prevalence of each type of jaw cyst during a lifetime may point toward a multifactorial polygenic pattern rather than a monogenic pattern.

Endoscopic treatment of salivary glands affected by autoimmune diseases.

PURPOSE: To asses the possibility of an endoscopic technique to diagnose, treat, and maintain the salivary glands in patients with Sjögren syndrome and systemic lupus erythematosus. PATIENTS AND METHODS: A total of 8 patients with Sjögren syndrome and 2 with systemic lupus erythematosus with affected salivary glands were included in the present study. The treatment approach included parotid sialoendoscopy with thorough rinsing, and Stenson's duct dilation using hydrostatic pressure and a high-pressure balloon. Hydrocortisone 100 mg was injected through direct vision into the duct. The study was exempt by the Barzilai Medical Center review board. RESULTS: The main diagnosis of the patients was chronic recurrent parotitis, with the exception of 1 patient, who presented with salivary stones. CONCLUSIONS: The pathologic features of the salivary glands resulting from Sjögren syndrome and systemic lupus erythematosus can be managed successfully using an endoscopic approach.

Endoscopic treatment of salivary gland injuries due to facial rejuvenation procedures.

OBJECTIVE: The purpose of this article is to describe innovative surgical techniques for treatment of salivary gland injuries caused by facial rejuvenation procedures. METHODS: Between 2001 and 2007, a total of 14 patients, all females ages 46 to 70 who suffered from salivary gland injuries caused by facial rejuvenation procedures, were treated, primarily by an endoscopic-guided technique that involved location of the injury and endoscopic repair. RESULTS: There were four types of postsurgical injuries of the salivary glands that were caused by operations for facial rejuvenation: 1) compression of salivary ducts with temporary swelling (n = 1); 2) laceration of the capsule of the salivary gland (n = 3); 3) stretching and compression of the ducts with penetration of the capsule of the duct leading to sialocele and long-term swelling (types 1 and 2 combined) (n = 5); and 4) complete cut or penetration of the main salivary duct or of one of its main branches resulting in sialocele (n = 5). The endoscopic technique treatment was successful in all cases. CONCLUSION: The main reasons for salivary gland injuries due to facial rejuvenation procedures in our patients were: poor anatomical identification of the border between the superficial muscular aponeurotic system (SMAS) and the parotid capsule; penetration of the salivary gland capsule by blunt or sharp dissection; unnecessary use of sharp-tip scissors; and a tear of the salivary duct by hooks during a face-lift procedure. Plastic surgeons should be aware of these complications and try to improve their techniques accordingly. To avoid atrophy of the salivary gland, once the diagnosis it made, it is advisable to send the patient to a maxillofacial or ENT surgeon skilled in endoscopy.
