Functional Swallowing Outcomes Following Transoral Robotic Surgery vs Primary Chemoradiotherapy in Patients With Advanced-Stage Oropharynx and Supraglottis Cancers

OBJECTIVES To evaluate functional swallowing outcomes in patients undergoing transoral robotic surgery vs primary chemoradiotherapy for the management of advanced-stage oropharynx and supraglottis cancers. DESIGN Prospective nonrandomized clinical trial. SETTING Academic research. PATIENTS We studied 40 patients with stage III or stage IVA oropharynx and supraglottis squamous cell carcinoma. Group 1 comprised 20 patients who received transoral robotic surgery with adjuvant therapy, while group 2 comprised 20 patients whose disease was managed by primary chemoradiotherapy. MAIN OUTCOME MEASURES Patients completed the M. D. Anderson Dysphagia Inventory (MDADI) before treatment and then at follow-up visits at 3, 6, and 12 months. The MDADI scores were analyzed and compared. RESULTS The median follow-up period for both groups was 14 months (range, 12-16 months). When comparing the median MDADI scores between group 1 and group 2, we found no statistically significant differences before treatment or at the 3-month follow-up visit. However, this difference was significant at the posttreatment visits at 6 months (P = .004) and 12 months (P = .006), where group 1 had better swallowing MDADI scores. We also found significant differences in swallowing MDADI scores between the groups at the 6-month posttreatment visit for patients with T1, T2, and T3 disease and at the 12-month follow-up visit for patients with T2 and T3 disease, where group 1 had significantly better MDADI scores. Comparing tumor subsites, group 1 fared significantly better at the follow-up visits at 6 months (P = .02) and 12 months (P = .04) for patients with primary tumor at the tonsil. Compared with group 2, group 1 patients having base of tongue cancers exhibited significantly better swallowing MDADI scores at the 6-month follow-up visit (P = .02), and group 1 patients having lateral oropharynx disease had significantly better swallowing MDADI scores at the 12-month follow-up visit (P = .04). CONCLUSION Advanced-stage oropharynx and supraglottis cancers managed by transoral robotic surgery with adjuvant therapy resulted in significantly better swallowing MDADI outcomes at the follow-up visits at 6 and 12 months compared with tumors treated by primary chemoradiotherapy.

Treatment outcomes for nontuberculous mycobacterial cervicofacial lymphadenitis in children based on the type of surgical intervention.

Objective To report treatment outcomes of nontuberculous mycobacteria (NTM) cervicofacial lymphadenitis. Study Design A retrospective study from 1995 to 2006. Subjects and Methods Fifty-one patients (mean age, 30.3 months). Results All but one patient presented with lymphadenopathy. The mean time from symptoms to diagnosis was 42.3 days. Tuberculin skin testing (TST) was performed on 21 of 51 patients and was positive on 14 of 21 patients. Imaging was ordered in 23; 19 had CT scans. Pathology confirmed caseating granuloma in 45 (88%); cultures grew Mycobacterium avium-intracellulare complex in 46 of 51. Interventions included fine-needle aspiration (5, 10%), incision and drainage ± curettage (24, 46%), and complete excisional biopsy (20, 38%). Of those who underwent complete excisional biopsy initially, 95 percent were cured compared with 32 of 51 (63%) with nonexcisional surgery. Macrolides and rifampin were more likely to be recommended in referred cases and when nonexcisional surgical treatment was not feasible or had failed. The average total duration of antibiotic therapy was 89.1 days. Conclusion NTM infections require high levels of suspicion for timely diagnosis, and complete excisional biopsy results in least likelihood of persistent/recurrent disease.

Partial Deafness Cochlear Implantation at the University of Kansas: Techniques and Outcomes

BACKGROUND One of the most significant recent advances in cochlear implantation is the implantation of patients with residual hearing. These patients have a downsloping sensorineural hearing loss with poor speech discrimination and perform poorly with standard amplification. Studies using a variety of different electrode designs have demonstrated that it is possible to implant an inner ear and preserve residual hearing. Initial studies have demonstrated that a combination of residual acoustic hearing in the low frequencies with electrical stimulation in the mid- to high frequencies resulted in superior hearing performance in background noise. PURPOSE The objective of this study was to determine the effect of electrode insertion depth on hearing preservation. STUDY SAMPLE Eighteen patients with mild to severe hearing loss in the low frequencies combined with poor word recognition were recruited for the study. INTERVENTION Cochlear implantation. DATA COLLECTION AND ANALYSIS Pre- and postoperative hearing test, Hearing in Noise Test, and consonant-nucleus-consonant testing. Data analysis was performed with Kruskal Wallis and Mann-Whitney testing. RESULTS In our study of 18 patients implanted with a Med-El PulsarCI100 we demonstrated the ability to preserve residual hearing with implant insertion depths ranging from 20 to 28 mm, giving us the possibility of near complete cochlear frequency coverage with an implant array while preserving residual hearing. These patients performed well both in quiet and in 10 dB signal-to-noise ratio conditions. CONCLUSION Hearing preservation was achievable even with deep implant insertion. Patients performed well in combined acoustic and electric conditions.

Outcomes of the Osteocutaneous Radial Forearm Free Flap for Mandibular Reconstruction

IMPORTANCE Limited donor and recipient site complications support the osteocutaneous radial forearm free flap (OCRFFF) for mandibular reconstruction as a useful option for single-stage mandibular reconstruction. OBJECTIVE To examine and report long-term outcomes and complications at the donor and recipient sites for patients undergoing the OCRFFF for mandibular reconstruction. DESIGN Retrospective review. SETTING Academic, tertiary care medical center. PATIENTS The study population comprised 167 consecutive patients who underwent single-staged mandibular reconstruction with an OCRFFF. MEAN OUTCOME MEASURES Rates of complications at the donor and recipient sites. RESULTS The mean patient age was 61 years (range, 20-93 years). Men compromised 68% of the population. Follow-up interval ranged from 2 to 99 months (mean, 25.9 months). The median length of bone harvested was 7 cm (range, 2.5-12.0 cm). Prophylactic plating was completed for each of the radii at the time of harvest. Donor site complications included radial fracture (1 patient [0.5%]), tendon exposure (47 patients [28%]), and donor hand weakness or numbness (13 patients [9%]). Recipient site complications included mandible hardware exposure (29 patients [17%]), mandible nonunion or malunion (4 patients [2%]), and mandible bone or hardware fracture (4 patients [2%]). Using regression analysis, we found that patients were 1.3 times more likely to have plate exposure for every increase of 1 cm of bone harvest length; this was statistically significant (P = .04). CONCLUSIONS AND RELEVANCE This is the largest single study reporting outcomes and complications for patients undergoing OCRFFF for mandibular reconstruction. Prophylactic plating of the donor radius has nearly eliminated the risk of pathologic radial bone fractures. Limited long-term donor and recipient site complications support the use of this flap for single-stage mandibular reconstruction.

A 7-Year Review of the Safety of Tonsillectomy during Short-Term Medical Mission Trips

Objective. To evaluate the safety of tonsillectomy in a short-term medical mission setting. Study Design. Retrospective chart review. Setting. Catholic mission hospital in Guatemala. Subjects and Methods. During 7 consecutive annual mission trips from 2004 to 2010, patients received tonsillectomy and adenotonsillectomy. Established safety protocol requires candidates for tonsillectomy to agree to stay within 1 hour of the hospital for 10 days following the operation. This study includes all tonsillectomy patients regardless of age or indication for tonsillectomy. The primary outcome measures include posttonsillectomy hemorrhage, nasopharyngeal reflux, readmission for dehydration, and mortality. This is a novel study as the work performed by most short-term medical missions is unregulated and unevaluated. Results. Medical charts were available for 197 (96.6%) of the 204 patients receiving tonsillectomy in the 7-year period; this was the only inclusion criterion. Ninety-nine (50.3%) patients had tonsillectomy concomitantly with adenoidectomy. Patients ranged in age from 3 to 66 years. The mean (SD) age was 17.2 (14.0) years. The study team found documentation of postoperative complications in 3 (1.5%) patients; 2 experienced postoperative hemorrhage, 1 within the first postoperative hour and 1 at 96 hours. The final patient returned to the hospital within 24 hours symptomatic for dehydration. Conclusions. The authors have evaluated a protocol for tonsillectomy patients in a specific setting and believe their data represent satisfactory outcomes for the reviewed patients. The generalizability of this information is uncertain, but safety protocols should be established on all short-term medical missions to prevent untoward complications.

Incidence of and risk factors for airway complications following endotracheal intubation for bronchiolitis

OBJECTIVE: To identify risk factors predisposing to postextubation complications and the incidence of subglottic stenosis following endotracheal intubation for bronchiolitis. STUDY DESIGN AND SETTING: A review of 144 consecutive infants and children intubated for bronchiolitis between 2000 and 2005 at a regional childrens hospital. RESULTS: The mean age at diagnosis was 6.4 months. Follow-up data were available in 93 patients (64.6%), and average length of follow-up was 9.3 months. One hundred and three patients (71.5%) had positive RSV detection. Average duration of intubation was 5.5 days. Twenty-six patients (18.1%) required reintubation during the same admission. Children intubated for less than 3 days and those greater than 12 months of age were more likely to experience postextubation difficulties. Approximately 40% of patients experienced postextubation difficulties. Subglottic pathology was found on endoscopy in 6 patients (4%). There were no cases of long-term subglottic stenosis. CONCLUSION: Immediate postextubation complications are common after bronchiolitis, especially in patients intubated for less than 3 days and greater than 12 months of age. We found no evidence of long-term subglottic stenosis in this population.

Practice patterns after tracheotomy in infants younger than 2 years.

OBJECTIVES To report survey results of members of the American Society of Pediatric Otolaryngology (ASPO) on the practice patterns of surveillance endoscopy and management of suprastomal granuloma (SSG) in children younger than 2 years with indwelling tracheostomy tubes and to review our internal practice patterns. PATIENTS All patients younger than 2 years who underwent tracheotomy between 1996 and 2006 at a tertiary childrens hospital. INTERVENTIONS (1) Retrospective medical chart summary and (2) ASPO-approved and -administered online surveys to the membership of a 14-question survey on indications for infant tracheotomy, indications for bronchoscopy after tracheotomy, and treatment preferences for SSG in this population. MAIN OUTCOME MEASURES Summary and findings of survey results and of data collected from medical chart review, including demographics, medical comorbidities, age at time of tracheotomy, indications for tracheotomy, frequency of bronchoscopy after tracheotomy, frequency of observed SSG, and interventions for SSG. RESULTS Seventy-five ASPO members completed the online surveys. Practice patterns varied for frequency of bronchoscopy: only as needed, every 12 months, every 6 months, and every 3 months were reported by 38% (n = 26), 25% (n = 17), 24% (n = 17), and 9% (n = 6) of ASPO members, respectively. Most important indications for bronchoscopy were preparation for laryngotracheal reconstruction and decannulation (100% [n = 65] and 92% [n = 60], respectively), bleeding (76% [n = 59]), and difficult tracheostomy tube changes (70% [n = 57]). Lumen obstruction of 25% to 50% and 50% to 75% by SSG would likely receive intervention (30% [n = 22] and 14% [n = 11], respectively) with skin hook eversion and removal being the most popular technique. We reviewed the medical records of a total of 201 infants who underwent tracheotomy at our institution (110 boys [54.7%]). Indications included ventilator dependence (32.2%), craniofacial anomaly (15.0%), cardiopulmonary insufficiency(15.0%), neuromuscular indication (15.0%), and subglottic stenosis (6.7%). Thirty patients (14.9%) were premature (mean gestational age, 27 weeks). Median age at time of tracheotomy was 4 months for premature infants and 3 months for term infants. Practice patterns regarding endoscopy and SSG management varied widely within our own institution. A total of 205 bronchoscopies were performed on 109 patients during the study period. At the time of first bronchoscopy 43 of 109 patients were noted to have an SSG (39.4%). Elective removal of SSG occurred in 20 of 43 cases (46.5%), and 9 of 20 patients were noted to have recurrent SSG at subsequent endoscopy (45%). In addition, of the 23 children who did not have intervention for their SSG, 15 of 23 had spontaneous resolution and no appreciable SSG at the time of follow-up endoscopy (65.0%). CONCLUSIONS There are currently various practice patterns for surveillance endoscopy and management of SSG in children younger than 2 years with indwelling tracheostomy tubes. Development of clinical practice guidelines on this topic may improve patient care and reduce unnecessary procedures.
