[Clinico-therapeutic observations on a series of cases of odontogenic abscesses and phlegmons].

The authors review 561 patients suffering from odontogenic abscesses and phlegmons which were large enough to merit hospitalisation in the Division of Maxillo-Facial Surgery of the Odontostomatological Clinic at the University of Turin during the period from 1972 to 1990. The main features of these septic processes are evaluated: site, size, mode of growth and evolution, tooth responsible. Special attention is paid to the treatment performed: this was essentially based on antibiotic therapy and/or drainage of the abscess via a transcutaneous, transmucous or transdental route. The need to combine medical therapy with surgical drainage of purulent material was noted in the treatment of large infections; in many cases medical therapy alone was unable to guarantee the resolution of the pathology; on the other hand, surgical drainage alone in some cases led to the patient's recovery.

[Tumors and the histogenesis of Schwann cells of maxillofacial competence].

After a brief review of published data relating to the clinical and anatomicopathological characteristics and therapeutic problems of tumours deriving from the nerve sheaths of the oromaxillofacial area, the paper reports 13 cases of these neoplasias observed from 1975 to 1988 in the maxillofacial surgery ward of the Dentistry Clinic at the University of Turin. The group include 6 schwannomas (neurinomas), 6 neurofibromas and 1 malignant schwannoma. Clinical symptoms and methods of diagnosis are described.

[The long-term clinical follow-up of a group of patients subjected to surgical intervention for the extraction of supernumerary impacted teeth].

A long-term clinical control carried out on 34 patients subjected to surgery for the removal of included extra teeth at the Odontostomatological Clinic of the University of Turin is reported. The patients had mostly been treated at ages between 7 and 12 followed up between 4 and 8 years later. Long-term damage, from an orthodontic viewpoint also, is not frequent and when present is not of particular importance. The operation, carried out early and with correct technique, does not cause particular damage to teeth or adjacent bone or nerve structures and does not create psychological traumas for the young patient. It is therefore advisable for the surgical removal of extra included teeth which are causing damage to adjacent structures to be programmed as early as possible so as to permit maximum functional and aesthetic recovery and to minimise to the utmost the consequences of the operation.

[334 cases of salivary gland neoplasms seen at the Dentistry and Otorhinolaryngology Clinics of the University of Turin. II].

Three hundred and thirty-four cases of salivary gland neoplasms are reported which were diagnosed by the Departments of Dentistry and Otolaryngology of the University of Turin. Data referring to patients under observation during the same period are compared. It is stressed that in order to obtain a statistically valid comparison of salivary gland neoplasms, the source of and chronological period relating to the sample group must be taken into consideration given the different statistical clinical methods adopted over the years by the two departments in question. The present study completes earlier research carried out by the same authors using this data.

[392 cases of neoplasms of the salivary glands seen at the Odontostomatologic and Otorhinolaryngologic Clinic of Turin University. I].

Three-hundred-ninety-two cases of salivary gland cancer observed at Turin University Dental and Ear, Nose and Throat Clinics have been examined. Statistical analysis of the age and sex of patients shows the importance of selecting the statistical population and of its origin for the purpose of reliable statistical study, examining the whole set and its structural breakdown in the two Clinics.

[Clinico-surgical evaluation of dental elements in bone inclusions].

Dental inclusions are assessed on the basis of clinical and operating statistics relating to the years 1981-1985 and comprising 815 patients and 1445 treated teeth. The results confirm the predominance of inclusions among female patients and the prevalence of the mandibular site; the most frequently included teeth are the lower eighths followed by the upper eighths, the upper canines and the second lower premolars. Inclusions are bilateral in most cases. These findings are in substantial agreement with the epidemiological data recorded in the literature. The operating series shows that the type of surgical treatment varies with the localisation of the tooth (anterior or posterior), its relationship with contigous teeth and with the surrounding anatomical structures and the age of the patient. Teeth in the posterior sector are usually extracted. At young age, germectomy is carried out for orthodontic purposes; at mature age, teeth are extracted to prevent the formation of periodontal pockets and the aggravation of caries and their complications. On the other hand, for teeth in the anterior sector, surgery is usually merely the first stage in treatment and is followed by treatment of orthodontic type with traction, in view of the important aesthetic and functional role of the labial teeth.

[Use of Lyodura in fractures of the orbital floor].

After a brief review of reported techniques for the reconstruction of substance losses of slight or modest proportions at the orbital floor using autogenic, homogeneous, heterogeneous and alloplastic grafts, personal experience with this type of surgery employing lyophilised human dura mater is reported. It is considered that Lyodura can be considered the material of choice by virtue of its strength, handiness and the absence of tissue reactions. 38 fractures of the orbital floor were treated from 1980 to 1986 with osteosynthesis of the border and insertion of lyophilised dura mater to make up for bone loss. In the immediate postoperative period and in later controls, there was no evidence of complications or phenomena of intolerance to the material. The patients treated were followed up a short time later. Clinical and X-ray data confirmed the validity in time of the technique and material employed long-term.

[Relationship between injury dynamics and site of maxillofacial fractures. Comparative study of 100 cases].

One hundred cases of facial mass fractures observed in the period April-September 1988 have been assessed using a clinico-anamnestic type investigation. Among trauma patients there is a prevalence of male patients aged between 10 and 30. Fractures located at the middle third and mandible occur in a practically equivalent number. Most traumas are the result of road accidents, following by falls. A good degree of correlation was observed between trauma aetiology and dynamics on the one hand and type and gravity of fractures on the other. Direct fractures, with greatest comminution of fragments prevail in high speed traumas; indirect fractures are most frequent in low speed traumas (cyclists and accidental).

[Clinico-surgical evaluation of supernumerary dental anomalies].

The pathology of extra teeth is evaluated on the basis of clinico-operative statistics for the years 1981-1985 and comprising 88 patients for a total of 115 treated teeth. The data obtained confirm the higher frequency of extra teeth in male patients. The most frequent site is easily the frontal sector of the upper arch. At that level, especially in males, two more or less symmetrical extra teeth are not infrequent. These data are in substantial agreement with the epidemiological data reported in the literature. Extra teeth are usually treated by surgical removal followed by orthodontic treatment to correct malformations caused by them and to recover the functional and aesthetic role of the upper front teeth.

[Apicoectomy: comparison between 2 case series].

Data on 2 series of apicectomies performed in 1966-69 and 1978-82 respectively are compared. The comparison was based on clinical assessments and radiographic findings in patients given a repeated check-up a later date. Similar results were obtained in the two series, confirming the importance of scrupulous pre-operative endodontic treatment combined with the use of non-absorbable canal material. It is felt that this, combined with a scrupulously precise periapical surgical technique will ensure total success in all cases.
