Study Design and SettingA two‐center prospective case series analysis.PatientsOne hundred fourteen patients with previously treated laryngeal or pharyngeal squamous cell carcinoma who underwent salvage transoral laser microsurgery (TLM).InterventionsTLM in 114 patients, neck dissection in 22 (19%) patients, adjuvant radiotherapy in 12 (11%) patients.ResultsNinety‐one (80%) patients had recurrent primary tumors whereas 23 (20%) patients had second primary tumors occur within a previously irradiated field. The minimum follow‐up was 1 year (median, 3 years). The distribution of tumor location was oropharynx 52 (46%), glottic and subglottic larynx 44 (39%), supraglottic larynx 11 (10%), and pyriform/hypopharynx 7 (6%). Overall, three‐year local and locoregional control estimates were 70 percent and 67 percent, respectively; and three‐year survival and disease‐free survival estimates were 62 percent and 64 percent, respectively. The average duration of hospitalization was 2.3 days. Four (3.5%) patients had significant postoperative bleeding. Two (<2%) patients had treatment‐related deaths.ConclusionsTransoral laser microsurgery offers select patients an attractive alternative salvage surgical therapy to the recurrent and second primary tumor site.
Transoral Laser Microsurgery for Untreated Glottic Carcinoma
OBJECTIVESTo report the oncology and functional outcomes of transoral laser microsurgery (TLM) for untreated glottic carcinoma.STUDY DESIGNA 2 center prospective case series analysis.SETTINGAcademic, tertiary referral centers.RESULTSSeventy‐six patients underwent TLM. Pathologic T stages were: T1, 45 (59%); T2, 21 (28%); T3, 5 (7%); and T4, 5 (7%). Five (7%) patients had neck dissections. Five (7%) patients received adjuvant radiotherapy. Mean follow‐up was 42 months. Respective T1 and T2 5‐year Kaplan‐Meier estimates were: local control, 90% and 93%; loco‐regional control, 90% and 93%; disease specific survival, 90% and 93%; and overall survival, 94% and 93%. The average hospital stay was 2 days. Two (3%) patients experienced major complications. The overall laryngeal preservation rate was 95% (72 of 76).CONCLUSIONSTLM is a safe and effective treatment in select carcinoma of the glottic larynx. Low morbidity and mortality and short periods of hospitalization make TLM an attractive therapeutic option.SIGNIFICANCETLM is an emerging strategy in the treatment of laryngeal cancer.
Transoral laser microsurgery for carcinoma of the supraglottic larynx
OBJECTIVETo illustrate the safety and efficacy of the endoscopic laser approach for cricopharyngeal myotomy (CPM) compared to the traditional transcervical approach.STUDY DESIGN AND SETTINGRetrospective chart review of 22 patients undergoing CPM from 1996 to 2003 at the Mayo Clinic, Jacksonville.RESULTSThe laser CPM technique was used in 14 patients, and an open approach in 8. The mean hospital stay and operative times were shorter for the laser group. Functional outcome analyses showed improvement in both groups. There were no major complications in the laser group, while 1 patient in the transcervical group had a pharyngocutaneous fistula.CONCLUSIONSThe laser technique is at least as effective as the transcervical approach for CPM to improve dysphagia symptoms in the properly selected patient, with a low risk of major complications.SIGNIFICANCEIn this report, we provide the reader with data to support the safety and efficacy of laser CPM.EBM rating: B‐3b
Comparison of Methods for Determining Cricopharyngeal Intrabolus Pressure in Normal Patients as Possible Indicator for Cricopharyngeal Myotomy
OBJECTIVEWe sought to compare methods for determining intrabolus cricopharyngeal pressure as a possible indicator for cricopharyngeal myotomy.STUDY DESIGNWe determined multiple intrabolus pressures in the cricopharyngeal region of 20 normal volunteers, of whom 12 were 20 to 35 years old and 8 were older than 75 years. Data were collected using a commercially available manofluorography system and a 6‐sensor unidirectional solid‐state 2‐ x 4‐mm catheter. Each subject underwent 5 5‐mL and 5 10‐mL liquid barium swallows. Data were analyzed, and young subjects were compared with old subjects.RESULTSThe mean mid‐bolus pressures in young subjects were 5.2 ± 4.9 mm Hg and 7.2 ± 6.5 mm Hg for the 5‐mL and 10‐mL swallows, respectively, and in older subjects, 10.8 ± 8.8 mm Hg and 12.3 ± 7.4 mm Hg. The mean gradient pressures across the 3‐cm cricopharyngeal region in young subjects were 2.02 ± 5.0 mm Hg, and −0.91 ± 4.8 mm Hg for the 5‐mL and 10‐mL swallows, respectively, and for older subjects, 4.38 ± 3.1 mm Hg and 2.82 ± 3.4 mm Hg.CONCLUSIONSCricopharyngeal intrabolus pressures were lower in young than in older subjects. The mid‐bolus pressure and the gradient pressure across the cricopharyngeal region appeared to be the most consistent methods for evaluating intrabolus pressures.SIGNIFICANCEIntrabolus pressure anomalies in the cricopharyngeal region have been proposed as an indicator for selecting patients who would benefit from cricopharyngeal myotomy. The methods of determining intrabolus pressures vary, with resulting variations in recommendations.
