Oral Lichen

Lichen planus (LP), although a dermatosis, is more common in the oral mucous membrane thanin the skin. Lesions of oral LP are classically found on the buccal mucosa and gingiva. Among thevarious types, the reticularlesions are asymptomatic and require no treatment, but pain and severediscomfort accompany the erosive or ulcerative lesions. Malignant transformation to squamouscell carcinoma developing in areas of erosive oral LP (EOLP) being a possibility, it is important forclinicians to maintain a high index of suspicion for all intraoral lichenoid lesions. Therefore, periodicfollow-up of all patients with EOLP is recommended.In view ofthe above,this paper highlights themanagement of four cases of EOLP with topical corticosteroid and CO2laser surgery.Key words: carbon dioxide laser, corticosteroid, lichen planus

Microlaryngeal Surgery

Introduction: The hemangioma is the most common vascular tumor, involving the head and neck in 60% of cases. It is rare in the larynx. In children, hemangiomas are more frequent on the subglottis, whereas in adults the most common site is the supraglottis. Laryngeal hemangioma with cavernous features isolated to the free edge of the vocal fold is a very rare clinical finding. We present 2 cases of glottic hemangioma. Both patients reported severe hoarseness. Cases: In the first patient, an extensive blue-purple mass was seen on the right vocal cord. The patient was posted for microlaryngeal surgery with carbon dioxide (CO2) laser. Second patient had a large, smooth, flesh-colored polypoid mass emanating from the left vocal cord. The patient was posted for microlaryngeal surgery. After 2 months, both patients showed a considerable voice improvement. Discussion: Vocal cord hemangiomas are very rare, and they usually cause problem in the voice of the patient. A vascular lesion that may mimic a hemangioma may sometimes result from an organizing hematoma following a hemorrhage on the vocal cords due to voice abuse. Laryngeal hemangiomas also need to be distinguished pathologically from polypoidal vascular granulation tissue that may be produced by laryngeal biopsy, intubation, or trauma. Indirect endoscopy is enough to diagnosis. No active treatment is advised for adult laryngeal hemangiomas unless the lesions are symptomatic or show a tendency to involve other parts. There is no uniformly accepted treatment of head and neck hemangiomas. Surgical excision with laser CO2 microlaryngoscopic techniques gives satisfactory results.

ObjectiveTo identify costs and operative times for stapedotomy and evaluate factors influencing cost variation.Study DesignCase series with cost analysis.SettingMultihospital network.Subjects and MethodsA multihospital network’s standardized activity-based accounting system was used to determine costs and operative times of all patients undergoing stapedotomy from 2013 to 2017. Subjects with additional procedures were excluded. Correlations between variable factors and cost were calculated by Spearman correlation coefficients. Audiometric and cost data were compared with a Mann-Whitney U test.ResultsThe study cohort included 176 stapedotomies performed by 23 surgeons at 10 hospitals. Mean ± SD patient age was 44.3 ± 17.4 years. Mean cut-to-close time was 61.1 ± 23.55 minutes. Mean total encounter cost was $3542.14 ± $1258.78 (US dollars). Significant factors correlating with increased total encounter cost were surgical supply cost ( r = 0.74, P < .0001) and cut-to-close time ( r = 0.66, P < .0001). Laser utilization ($563.37 ± $407.41) was the highest-cost surgical supply, with the carbon dioxide laser being significantly more costly than the potassium titanyl phosphate (KTP; $852.60 vs $230.55, P < .001). Additionally, the carbon dioxide laser was associated with a significantly higher mean total encounter cost than the KTP laser ($4645.43 vs $2903.00, P < .001) and cases where no laser was used ($4645.43 vs $2932.47, P < .001). There was no difference in mean total encounter cost between the KTP laser and cases of no laser use ($2903.00 vs $2932.47, P = .75).ConclusionsSignificant cost variation exists in stapes surgery. Surgical supply cost, specifically laser use, may be associated with significantly increased costs. Reducing variation in costs while maintaining outcomes may improve health care value.

Retrospective Case Study

Most clinical studies on carbon dioxide (CO2) (λ = 10.6.mm) laser stapedotomy have been carried out with the laser guided by a conventional lens-based micromanipulator, with the attendant risks of correct aiming (HeNe) and surgical (CO2) beam misalignment. Hence, engineering advances have attempted to improve laser targeting as well as the spot size focus. The development of the mirror-based micromanipulator was a response to this need but no data concerning its use in stapes surgery is available. We performed a retrospective case-series review of patients treated for otosclerosis between 1992 and 2000. Primary laser stapedotomy was performed in 218 consecutive patients. In the first 78 procedures, the aiming beam (HeNe, λ = 632 nm) and surgical beam (CO2) were guided with a conventional lens-based micromanipulator whereas in the subsequent 140 procedures, they were guided by using a mirror-based micromanipulator. Hearing was tested at six and 12 months. The mean (SD) air-bone gap was 5 dB (4.5) and 4.5 dB (3.9). The mean closure was 15 dB (9.9) and 14.4 dB (9.4). The mean change in the high-tone bone-conduction level was 5.5 dB (7.3) and 7.8 dB (7.5). Overheating of the facial canal produced transient facial paralysis in one case and was due to misalignment of the beams with the lens-based micromanipulator. Use of the mirror-based micromanipulator obviated the need to verify alignment. The light-weight and superior optical yield of this system made it possible to reduce the number of impacts on the footplate by the integral restitution of the energy source. This study demonstrated that the CO2 laser is an effective method for performing stapedotomy. In addition, microtrauma to the labyrinth is reduced by its ability to perform calibrated footplate fenestration without mechanical or vibrational injury to the inner ear. The optical reflection micromanipulator simplified beam alignment and enhanced surgical comfort.
