PURPOSE: The impact of postoperative ipsilateral neck radiotherapy (INRT) versus bilateral neck radiotherapy (BNRT) on the clinical outcomes of patients with tonsillar squamous cell carcinoma was analyzed retrospectively. MATERIALS AND METHODS: Between October 2001 and June 2012, 241 patients with T1-2 and N0-N2b tonsillar carcinoma from 16 institutes underwent postoperative INRT (n=84) or BNRT (n=157) following a tonsillectomy. Seventy patients were identified from each group by propensity score matching and compared in terms of the overall survival (OS), disease-free survival (DFS), locoregional relapse-free survival (LRRFS), and distant metastasis-free survival (DMFS) rates calculated using the Kaplan-Meier method with a log-rank test. RESULTS: The median follow-up was 55 months (range, 3 to 133 months). The survival outcomes in the INRT and BNRT groups were similar: 5-year OS (92.8% vs. 94.0%, p=0.985), DFS (80.5% vs. 94.2%. p=0.085), LRRFS (88.1% vs. 97.1%, p=0.083), and DMFS (92.7% vs. 97.0%, p=0.370). Subgroup analysis revealed no contralateral neck recurrence in 61 patients with T1-2N0-2a regardless of the treatment groups. For 79 patients with N2b, contralateral neck recurrence was more common in the INRT group than in the BNRT group (7.9% vs. 0.0%), but the difference was not significant (p=0.107). The overall grade ≥ 2 toxicities were lower in the INRT group: acute (45.7% vs. 74.3%, p=0.001) and late (4.3% vs. 31.4%, p < 0.001), respectively. CONCLUSION: INRT is an attractive strategy for patients with T1-2N0-2a tonsillar carcinoma compared to BNRT. For patients with N2b, there was a small risk of contralateral neck recurrence when treated with INRT, but its impact on the OS was limited with successful salvage treatment.

Grisel's syndrome, defined as the atlanto-axial joint subluxation not associated with a trauma or bone disease, is a rare complication following operative procedure and/or infections of the upper aerodigestive tract. Pathogenetically, it may occur in association with any condition that results in hyperemia and pathological relaxation of the transverse ligament of the atlanto-axial joint. When an inflammation heals, Grisel's syndrome can probably result in a fixation in the rotated position. It is diagnosed by physical and radiological findings. Early management, consisting of cervical immobilization and medical treatment, is considered a key factor for satisfactory outcome. Inappropriate treatment can result in a catastrophic consequence. Recently, we experienced a case of Grisel's syndrome following tonsillectomy in a patient with left palatine tonsillar cancer with preoperative radiotherapy. We report this case with a literature review.

Heterotopic calcification following head and neck irradiation has rarely been reported. It usually develops as a late complication of radiotherapy in patients with malignancies, including breast cancer, lymphoma, and genitourinary malignancies. The occurrence of heterotopic calcification in the prevertebral space of the cervical spine has not been described as a late complication of irradiation. Here, we report a case of prevertebral heterotopic calcification in a patient with history of chemotherapy and radiotherapy for tonsil cancer 21 years ago.

Osteoradionecrosis is one of the most serious complications of patients receiving radiation therapy. It is characterized by hypovascularity, hypocellularity, and hypoxia-inducing necrosis of bone and soft tissue following delayed healing. In this case, a 72-year-old man was referred to the Department of Oral and Maxillofacial Surgery complaining of trismus following extraction three months before first visit. He had a history of right tonsillectomy, radical neck dissection and radiotherapy performed due to right tonsillar cancer seven years prior. After the diagnosis of osteoradionecrosis on right mandibular body and angle, conservative antibiotic therapy was used first, but an orocutaneous fistula gradually formed, and extensive bony destruction and sequestrum were observed. Sequestrectomy, free particulated iliac bone and umbilical fat pad graft were performed via a submandibular approach under general anesthesia. Preoperative regular exams and delicate wound care led to secondary healing of the wound without vascularized free flap reconstruction.

PURPOSE: The purpose of this study is to analyze treatment outcome of radiotherapy (RT) in patients with stage III-IV tonsil cancer managed by surgery followed by postoperative RT (SRT) and definitive chemoradiotherapy (CRT), and to thereby evaluate the most feasible treatment modality. MATERIALS AND METHODS: Of 124 patients, 67 underwent CRT, and 57 underwent SRT. We compared survival and complication rates in both groups. RESULTS: The median follow-up time was 57 months (range, 19 to 255 months) for surviving patients. At five years, locoregional progression-free survival (LRPFS) and overall survival (OS) were 88% and 80%, respectively. No significant difference in LRPFS (p=0.491) and OS (p=0.177) was observed between CRT and SRT. In multivariate analysis, old age and higher T stage showed a significant association with poor LRPFS, PFS, and OS; higher N stage showed an association with poor PFS and a trend of poor LRPFS, while no association with OS was observed; treatment modality (CRT and SRT) showed no association with LRFPS, PFS, and OS. Grade 3 or higher mucositis was observed in 12 patients (21%) in the SRT group, and 25 patients (37%) in the CRT group. CONCLUSION: Definitive CRT and SRT have similar treatment outcomes for patients with stage III-IV tonsil cancer. Although acute complication rate appears to be higher in the CRT group, it should be noted that not all data on complications were included in this retrospective study. To determine the most feasible treatment modality, not only mucositis and xerostomia, but also emotional aspect and quality of life, should be considered.

PURPOSE: We wanted to present the preliminary results of intensity-modulated radiotherapy (IMRT) for the treatment of tonsillar cancer. MATERIALS AND METHODS: We retrospectively analyzed 12 patients who underwent IMRT for tonsillar cancer at Asan Medical Center between November 2002 and February 2007. Seven patients (58%) received definitive treatment, and five (42%) were treated in the postoperative setting. Among the definitively treated patients, 6 patients received cisplatin-based chemotherapy regimens. Simultaneous modulated accelerated radiation therapy (SMART) was used in nine patients. The prescribed dose was 72 Gy at 2.4 Gy/fraction for the definitively treated cases and 61.6 Gy at 2.2 Gy/fraction for the postoperative cases. The median follow-up period was 34 months. RESULTS: All twelve patients completed treatment without interruption, and eleven showed a complete response. One patient had persistent loco-regional disease after treatment. The three-year estimates of loco-regional control, disease-free survival and overall survival were 91.7%, 91.7%, and 100%. The worst acute mucositis was Grade 1 in four patients, Grade 2 in five patients, Grade 3 in two patients and Grade 4 in one patient. Grade 3 xerostomia was observed in six patients. CONCLUSION: Intensity-modulated radiotherapy was shown to be a safe and effective treatment modality for tonsillar cancer. Further studies with a larger number of patients and a longer follow-up period are needed to evaluate the ultimate tumor control and late toxicity of IMRT for treating tonsillar cancer.

OBJECTIVETo explore a better approach to resect the advanced oropharyngeal carcinoma.

METHODSFrom 1995 to 2005, 17 patients underwent mandibular swing procedure for excision of advanced oropharyngeal carcinoma including: 13 tonsillar cancers, 2 soft palate carcinomas and 2 lingual root cancers. Surgical procedure was selected according to the lesion. All tumors were resected through the mandibular swing approach or its combined approaches. Immediate reconstruction of the surgical defect was done using tongue flap, pectoralis major myocutaneous flap, sternohyoid myofascial flap, temporalis myofascial flap and forehead flap, respectively. After surgical resection of the tumors, all patients received postoperative radiotherapy.

RESULTSAll patients' advanced oropharyngeal carcinoma were successfully resected as planned through the mandibular swing procedure or its combined procedures without severe complications. Functions of deglutition, respiration and speech were well restored. The 3- and 5-year survival rate was 54. 5% and 40%, respectively.

CONCLUSIONThe mandibular swing procedure and its combined approach is safe and effective in the surgical resection of the advanced oropharyngeal carcinoma, which can provide a good exposure for the oropharynx, supraglottic region, hypopharynx, the parapharyngeal space and the base of the skull.

OBJECTIVE: To evaluate the treatment of advanced tonsillar carcinoma by radiotherapy plus salvage surgery (R+S) or surgery coupling with postoperative radiotherapy (S+R). METHOD: Clinical data of 48 patients with advanced tonsillar carcinoma who were treated in The 2nd Affiliated Hospital of Sun Yat-sen University from June 1996 to June 2004 was retrospectively analyzed. The patients were divided into R+S group (group A, 21 cases) and S+R group (group B, 27 cases). Treatment outcomes were compared between these two groups. The QOL (quality of life) scale of Washington University (UW-QOL) was used to investigate the patient's quality of life. RESULT: The 5-year survival rates were 42.9% in group A and 45.8% in group B, there was no significant statistical difference between the two groups (P < 0.05). Both the two treatment modalities could reduce the QOL in some degree. The average QOL score of 46 patients was 661.00 +/- 98.52 , group A was 696.09 + 90.70, while group B was 631.52 +/- 96.74, there was a significant statistical difference between the two groups (P < 0.05). CONCLUSION The two treatment modalities reached similar survivals. However, compared with the S+R, some patients who accepted treatment of R+S could avoid composite resection, reduce functional lesion and improve the QOL.
