Cryogen spray cooling for spatially selective photocoagulation of hemangiomas: a new methodology with preliminary clinical reports.

Spatially selective photocoagulation of subsurface-targeted blood vessels by repetitive application of a short cryogen spurt during continuous Nd:YAG laser irradiation has been demonstrated in two human cases. This procedure may be effective for the treatment of thick hemangiomas that require photocoagulation of subsurface blood vessels while protecting the epidermis.

Stathmokinetic failure to enhance radiation response in human tumours.

The literature concerning the use of metaphase inducing agents as clinical sensitisers to radiation is briefly reviewed, and five cases are reported, which suggest that under ordinary clinical conditions, these agents are not likely to be of value. These results accord with animal experiments and a possible reason is suggested.

Results of irradiation in cancer of the lip, tongue and ear.

CANCER OF THE LIP: The primary lesion can be controlled by irradiation in approximately 80 per cent of cases. For lesions with metastases there is only about a 25 per cent chance of five-year arrest (irradiation of the primary lesion followed by excision of involved nodes). CANCER OF THE TONGUE: Lesions in the anterior two-thirds are controllable by irradiation in about 50 per cent of cases if the nodes are not involved; the salvage is only about 15 per cent if the nodes are involved (nodes treated surgically). Lesions in the posterior third of the tongue are seldom controlled in the author's experience. CANCER OF THE EAR (AURICLE): Five-year arrest of basal-cell lesions should be attained by irradiation in about 80 per cent of cases; of squamous-cell lesions in about 60 per cent. If the lesion is extensive, radiation does not offer a superior cosmetic result to operation and entails danger of late chondronecrosis. Therefore extensive lesions are probably best treated surgically. In either event, it appears probable that results of irradiation can be improved by the use of more adequate fields and greater fractionation.

Clinical manifestations and diagnostic approach to metastatic cancer of the mandible.

In a 12-month period, metastatic cancer was diagnosed in eight patients. Six of them presented with pain mimicking toothache, temporomandibular joint disorders or trigeminal neuralgia, while two showed osteopenic bone lesions in the panoramic radiography, and perimandibular swelling. Anesthesia of the lower lip was the only common clinical feature. In seven of the eight patients, a whole body bone scintigraphy and single photon emission computed tomography (SPECT) of the skull in combination with a whole body and SPECT anti-granulocyte (Tc-99m MAK 250/183) bone marrow scintigraphy was performed. One patient did not have combined scintigraphy performed secondary to severe systemic illness. In six of the seven, the results were conclusive for a metastatic bone lesion. Biopsies confirmed three patients to have a previously unrecognized primary cancer, one patient to have previously unrecognized recurrent cancer, and three patients to exhibit new metastatic spread of an already diagnosed cancer. Histology revealed breast, lung, renal cancer and a malignancy of inconclusive origin. In the remaining patient, combined scintigraphy suggested osteomyelitis, yet biopsy revealed a prostate cancer metastasis with acute inflammatory cell infiltration. Thus, the scintigraphy pattern of a hot spot in the bone scan and a cold lesion in the bone marrow scintigraphy is highly suggestive of a mandibular metastasis, if accompanied by anesthesia of the lower lip.

Primary reconstruction of complex midfacial defects with combined lip-switch procedures and free flaps.

Free flaps are generally the preferred method for reconstructing large defects of the midface, orbit, and maxilla that include the lip and oral commissure; commissuroplasty is traditionally performed at a second stage. Functional results of the oral sphincter using this reconstructive approach are, however, limited. This article presents a new approach to the reconstruction of massive defects of the lip and midface using a free flap in combination with a lip-switch flap. This was used in 10 patients. One-third to one-half of the upper lip was excised in seven patients, one-third of the lower lip was excised in one patient, and both the upper and lower lips were excised (one-third each) in two patients. All patients had maxillectomies, with or without mandibulectomies, in addition to full-thickness resections of the cheek. A switch flap from the opposite lip was used for reconstruction of the oral commissure and oral sphincter, and a rectus abdominis myocutaneous flap with two or three skin islands was used for reconstruction of the through-and-through defect in the midface. Free flap survival was 100 percent. All patients had good-to-excellent oral competence, and they were discharged without feeding tubes. A majority (80 percent) of the patients had an adequate oral stoma and could eat a soft diet. All patients have a satisfactory postoperative result. Immediate reconstruction of defects using a lip-switch procedure creates an oral sphincter that has excellent function, with good mobility and competence. This is a simple procedure that adds minimal operative time to the free-flap reconstruction and provides the patient with a functional stoma and acceptable appearance. The free flap can be used to reconstruct the soft tissue of the intraoral lining and external skin deficits, but it should not be used to reconstruct the lip.

Multiple glomus tumors of the face and eyelid.

The glomus tumor is a benign, vascular, hamartomatous derivative of the glomus body, a normal intradermal arteriovenous anastomosis. Most glomus tumors are solitary, tender lesions of the nail bed and are found only rarely on the eyelid. Occasionally, glomus tumors assume a multiple form, wherein they are nontender. I report a unique case of multiple glomus tumors involving the face, palate, eyelid, and anterior orbit.

Clinical guidelines in early detection of oral squamous cell carcinoma arising in oral lichen planus: a 5-year experience.

In recent years, studies on the malignant potential of oral lichen planus (OLP) provided clinical evidence that patients affected by OLP have an increased risk to develop oral squamous cell carcinoma (OSCC); nevertheless, controversies still exist as to whether OLP has inherent predisposition to become malignant, or not. We believe extremely careful management of OLP patient is mandatory, and the aim of this paper is to illustrate our clinical guidelines in evaluating the possible risk of transformation in OLP lesions. Five-hundred and two patients (311 women and 191 men) affected by OLP regularly undergo follow-up examination in our Department. Patients' ages range from 18 to 83 years, with a mean of 55.4 years (57.5 for women and 53.9 for men); minimal follow-up period is 4 months, with a maximum of 12 years. In our group of OLP patients in the past 5 years we detected 24 carcinomas: excluding three cases in which diagnoses of OLP and OSCC were synchronous and three patients who had a history of tobacco use, thus possible malignant transformation of OLP would appear to be 3.7%. Clinical criteria used in our follow-up allowed us to detect 28.5% of tumours as in situ OSCC, 38% as microinvasive OSCC, 28.5% as stage I OSCC and 4.7% as stage II OSCC, with a remarkable improvement in prognosis compared to our previous study in which we adopted different criteria.
