[Latent, non-suppurative mastoiditis. Apropos of 62 cases].

The term masked mastoiditis defines a subclinical infectious inflammatory process of the mucosal lining and bony structures of the mastoid air cells with an intact tympanic membrane. The disease follows an apparently well treated recent acute otitis media. Probably due to an anaerobic colonizing flora, the developing bone infection is of low grade without pus formation. The clinical features of the disease are not overt as those in coalescent mastoiditis. The intact ear drum does not reflect the severity of bone eroding disease which is characterized by non-exudative but proliferative changes. Hence there is no pus formation. The incidence of complications is high. Plain X-ray film and CT scan do not specifically define the disease process. Bone scan indicates the bone invading nature of the mastoid infection. The osteoblastic reaction secondary to osteitis is demonstrated by the high uptake of the isotope in the involved mastoid. Antibiotics may cure the disease process but in most of the cases surgery in unavoidable.

[Masked mastoiditis].

Masked mastoiditis defines a subclinical infectious inflammatory process of the mucosal lining and the bony structure of the mastoid air cells, with intact tympanic membrane. It follows an apparently well-treated recent acute otitis media. Because of obstruction of the tympanic diaphragm by mucosal swelling, polypoid mucosa or granulation tissue, a complete separation of the tubo-tympanic cavity from the mastoid air cell system results. The latter remains unaereated and the local infectious mucosal disease progresses to osteitis. Probably due to colonizing flora in this unventilated media, the developing bone infection is low-grade, without pus formation. The clinical features of the disease are not overt as those in coalescent mastoiditis. The intact ear drum does not reflect the severity of bone-eroding disease within the mastoid. Since this disease is characterized not by exudative but by proliferative changes, there is no pus formation. The incidence of complications is high. Plain x-ray and CT scan do not specifically define the disease process, but bone scan indicates the bone-invading nature of the mastoid infection. The osteoblastic reaction secondary to osteitis is demonstrated by high uptake of the isotope in the involved mastoid. Antibiotics may cure the disease, but in most cases surgery is unavoidable.

Osteoblastic osteitis of the maxillary sinus.

Osteoblastic osteitis is a rare kind of bone infection typified by a proliferative reaction of the periosteum and by exuberant bone formation. In the maxillary sinus, it occurs as a consequence of chronic or recurrent sinusitis. It usually manifests with a vague facial discomfort, followed by complications in the deep facial spaces or fossae. The diagnosis is a radiological one. Eradication of this bone infection necessitates removal of the precipitating condition as well as the long-term administration of appropriate anti-biotics. In the case of a deep facial fossae abscess, drainage is mandatory.

Early treatment of orbital floor fractures with catheter balloon in children.

Fifteen pediatric patients with orbital floor fractures were successfully treated early, following injury by a transantrally introduced catheter-balloon technique. The latter stabilizes and supports the torn, but still vascularized periosteum at the edges of the fracture and also serves as a guide for its further proliferation and new bone formation. Apart from a transient anesthesia in the dermatome of the infraorbital nerve in certain patients no complication or sequela was noted in this series. Accordingly early repair with the use of catheter-balloon appears to be a viable alternative in the repair of orbital floor fracture in children.

Effects of sodium hypochlorite on soft tissues after its inadvertent injection beyond the root apex.

The effects of an inadvertent injection of sodium hypochlorite into the cheek during irrigation of the right maxillary central incisor root canal are reported. The patient suffered from severe pain, edema, and necrosis of subcutaneous tissues and mucosa. Surgical intervention was necessary to contain the destructive process which extended from the upper lip to the right eye. The histopathological examination demonstrated the high cytotoxicity of sodium hypochlorite on vital tissue.

Air cyst of the maxillary sinus (pneumosinus dilatans, pneumocoele).

A cystic dilatation of a paranasal sinus by an entrapped air mass has been termed pneumosinus dilatans or a pneumocoele. The occurrence of this condition in the maxillary sinus is quite rare. In the present case, a mid-face mass mimicking an osteoma was the presenting sign of the disease. The pathogenesis, clinical features and radiological aspects of this entity are reviewed. In order to avoid confusion with other conditions of different aetiopathogenesis, we propose to label the lesion as 'air cyst' of the paranasal sinus, a term that best describes the nature of the lesion.

C.T. demonstration of metastatic anaerobic orbital abscess.

Orbital abscess of rhinosinogenic origin may develop, either by contiguous spread of the infection or by a thrombophlebitic process. While destruction of the bony walls of the paranasal sinus occurs in propagation of the infection by tissue continuity, haematogenous spread may take place through intact bone. Computed tomography demonstrates the status of the bony partitions shared by the orbit and paranasal sinuses, and the source of the orbital sepsis, thereby influencing the therapeutic approach.

Endodontic overextension produced by injected thermoplasticized gutta-percha.

Obturation of the root canal space with an inert filling material and creation of a hermetic apical seal has been shown to improve the success rate of endodontic therapy. A new technique of canal obturation with injection-molded thermoplasticized gutta-percha has been shown to create a good apical seal. However, failure to determine accurately the canal working length and create an apical stop in sound dentin can lead to overextension of the gutta-percha into the periradicular bone. A case of significant overextension of gutta-percha using this new technique is presented along with its ramifications and management.

Widespread oral papillomatosis due to chronic buccal trauma.

We present a case of oral papillomatosis occurring in a 52-year-old woman. This condition is well known and is characterized by an exuberant proliferation of multiple, flat, verruca-like elevations on the oral and pharyngeal mucosa. This is apparently the first documented case of oral papillomatosis due to trauma to the oral tissue from a dental prosthesis, with subsequent inflammation. Correction of the prosthesis resulted in marked improvement. This presentation emphasizes the causes, diagnosis, pathologic basis, and treatment of this condition.

Superior vena cava syndrome: presenting symptom of silent otitis media.

An extensive lateral sinus thrombosis secondary to silent otitis media, in a patient with a nephrotic syndrome, is presented. The thrombotic process progressed asymptomatically until the occlusion of the superior vena cava. Removal of the intractable pathology within the mastoid and administration of appropriate antibiotic therapy, prevented the further propagation of the life-threatening condition.

Prednisone treatment for injury and compression of inferior alveolar nerve: report of a case of anesthesia following endodontic overfilling.

An injury of the inferior alveolar nerve is not an uncommon occurrence. We envisage the physiopathologic process of this involvement. One case of injury of the nerve by endodontic overfilling is presented and analyzed. Prednisone therapy appears to shorten the course of the disease, prevent the secondary fibrosis, and lessen the severity of sequelae.

Periorbital cellulitis: presenting feature of undiagnosed old maxillary fracture.

Two cases of initially undiagnosed silent fractures of the medial wall of the maxillary sinus complicated by a delayed osteomyelitis are presented. The presenting feature was periorbital cellulitis. The etiopathogenesis of this process is based on an interference with the sinus ostium function by ingrowth of hypertrophic scar tissue.

Recurrent suppurative thyroiditis due to fourth branchial pouch sinus.

Acute suppurative thyroiditis is a rare disease in childhood. The etiology of this condition is not always obvious. The description of a pharyngeal pouch fistula extending from the pyriform sinus to the thyroid gland or perithyroid area, high-lighted the etiopathogenesis of some of the thyroiditis cases. Presented here are the clinical, radiological and pathological aspects of an internal pharyngeal fistula manifesting with recurrent suppurative thyroiditis, until it was completely removed. The clinical features of caudal branchial pouch remnants and their role in the development of acute suppurative thyroiditis is reviewed.
