Background. In spite of preservation of the accessory nerve there is still considerable proportion of patients with partial nerve damage during modified radical neck dissection (MRND).
Methods. The ...nerve was identified during the surgery and its branches for the trapezius muscle mapped with nerve monitor.
Results. The accessory nerve was mapped during 74 hemineck dissections and three patterns were identified. In type 1 nerve exits at the posterior end of the sternocleidomastoid muscle (SCm) and then it enters the level V (66%). In type 2 the nerve for trapezius muscle branches off before entering the SCm (22%). In type 3 the nerve exits at the posterior part of the SCm and it joins to the cervical plexus (12%). The nerve than exits this junction more medially as a single trapezius branch.
Conclusions. The description of three anatomical patterns in level II and V could help preserving the trapezius branch during MRND.
Background. The temporary tracheostoma’s metastases of head and neck cancer had already been reported in the literature. So far, they had been considered as regional dissemination of the malignant ...disease. We report a case of temporary tracheostoma’s metastasis of carcinoma from non-head-and-neck primary site, what has not been reported in the literature, yet. Therefore, it is the first reported case of the systemic dissemination of malignant tumour into temporary tracheostoma.
Case report. Fifty-four-year-old female patient, previously treated for a rectal adenocarcinoma, reported in our office with exophytic pink tissue masses around the temporary tracheostoma. The biopsy and immunohistochemistry findings were consistent with temporary tracheostoma’s metastasis of the rectal adenocarcinoma. The patient received palliative radiotherapy and died of systemic progression of the disease.
Conclusions. The patients with history of primary cancer of any origin and exophytic proliferating changes around the tracheostoma require an appropriate diagnostic work-up including a biopsy. The type of treatment depends on the extent of the disease, previous therapy and general condition of the patient
Objectives/Hypothesis
The diagnostic gain of narrow band imaging in the definition of surgical margins in the treatment of head and neck cancer was evaluated.
Study Design
A prospective study, ...blinded to the pathologist, with historical comparison.
Methods
The study group included 45 patients subjected to the intraoperative definition of margins by narrow band imaging. The control group included 55 patients who had undergone standard definition of margins. All patients underwent resection of the tumor and frozen section analysis of superficial margins. The rate of initial R0 resection and the ratio of histologically negative margins for both groups were statistically compared.
Results
The rate of initial R0 resection in the study group and in the control group was 88.9% and 70.9% (P = .047), and the ratio of histologically negative margins was 95.9% and 88.4% (P = .017), respectively.
Conclusions
Narrow band imaging reveals a microscopic extension of the tumor that could be effectively used to better define superficial margins and to achieve a higher rate of initial R0 resections.

The long term results and patterns of failure in patients with squamous cell head and neck carcinoma (SCHNC) treated in a prospective randomized trial in which concomitant postoperative ...radiochemotherapy with Mitomycin C and Bleomycin (CRT) was compared with radiotherapy only (RT), were analyzed.
Between March 1997 and December 2001, 114 eligible patients with Stage III or IV SCHNC were randomized. Primary surgical treatment was performed with curative intent in all patients. Patients in both groups were postoperatively irradiated to the total dose of 56-70 Gy. Chemotherapy included Mitomycin C 15 mg/m2 after 10 Gy and 5 mg of Bleomycin twice weekly during irradiation. Median follow-up was 76 months (48-103 months).
At 5 years in the RT and CRT arms, the locoregional control was 65% and 88% (p = 0.026), disease-free survival 33% and 53% (p = 0.035), and overall survival 37% and 55% (p = 0.091) respectively. Patients who benefited from chemotherapy were those with high-risk factors. The probability of distant metastases was 22% in RT and 20% in CRT arm (p = 0.913), of grade III or higher late toxicity 19% in RT and 26% in CRT arm (p = 0.52) and of thyroid dysfunction 36% in RT and 56% in CRT arm (p = 0.24). The probability to develop a second primary malignancy (SPM) was 34% in the RT and 8% in the CRT arm (p = 0.023). One third of deaths were due to infection, but there was no difference between the 2 groups.
With concomitant radiochemotherapy, locoregional control and disease free survival were significantly improved. Second primary malignancies in the CRT arm compared to RT arm were significantly less frequent. The high probability of post treatment hypothyroidism in both arms warrants regular laboratory evaluation.
Inverted papillomas (IPs) are the most frequent type of sinonasal papillomas. These benign but destructive lesions are known for their high recurrence rate, probably due to incomplete excision. Our ...aim was to investigate the frequency of human papillomavirus (HPV) infection in patients with IPs and in IPs associated with squamous cell carcinoma (IPsSCC) and to compare it with the frequency of HPV infections in the control group. The influence of HPV infection on the malignant alteration and recurrence rate of IPs was also evaluated. Paraffin-embedded tissue samples from 68 patients with sinonasal IPs and 5 patients with IPsSCC were analyzed in this retrospective study. The control group consisted of 47 patients who had undergone septoplasty or mucotomy of the inferior turbinate. PCR amplification with consensus primer sets was performed to detect alpha-HPVs, and direct sequencing of the PCR products with the same primers was used to determine the HPV genotypes in the samples. We detected HPV DNA in 20 (30.3%) patients with IPs, in 3 (60%) patients with IPsSCC, and in 6 (13%) patients from the control group. The frequency of HPV infection in the study group was statistically significantly higher (
p
= 0.032) than in the control group. The presence of HPV DNA was not a statistically significant predictor of the recurrence of IPs (
p
= 0.745) nor was it a statistically significant risk factor for associated SCC (
p
= 0.32). Since HPV type 11 was the predominant genotype in the IPs, IPsSCC, and in the control cases, we presume that HPV infection may represent incidental colonization rather than being an important etiological factor of IPs.
In the case of an aggressive course of recurrent respiratory papillomatosis (RRP), adjuvant therapy can be used besides surgery. The aim of the study was to investigate the influence of vaccination ...with a quadrivalent vaccine against human papilloma viruses (HPV) types 6, 11, 16 and 18 on the course of RRP. Eleven subjects aged 13–46 years with a rapid growth of laryngeal papillomas were included in the study. They were vaccinated with three doses of the quadrivalent prophylactic HPV vaccine (Silgard
®
, MSD) and followed up for 12–52 months. The intervals between the successive surgical procedures, the extension of the disease (Derkay score) at each surgery, and the number of surgical procedures per year before vaccination and after its completion were compared. The mean interval between the surgical procedures was 271.2 days before the vaccination and 537.4 days after it (
p
= 0.034). The mean number of surgeries per year was 2.16 before the vaccination and 0.93 after it (
p
= 0.022). The Derkay score did not change significantly after vaccination. Complete remission of the disease was observed in one patient, partial response to the vaccination was observed in seven patients and no response was observed in three patients. In conclusion, vaccination with the quadrivalent HPV vaccine can favorably influence the course of RRP in patients with the rapid growth of the papillomas. It significantly prolongs the intervals between the surgical procedures and reduces the number of procedures needed in the majority of patients. The present investigation can serve as a pilot study for further research. For a final conclusion a longer follow-up and studies on more patients are necessary.
A pharyngocutaneous fistula is the most common complication following laryngectomy. A wide range of potential risk factors has been suggested. The purpose of this study was to determine the incidence ...and risk factors for the fistula at the Department of Otorhinolaryngology and Head and Neck Surgery in Ljubljana, Slovenia between 2007 and 2012. Charts from patients treated for head and neck cancer by laryngectomy were retrospectively reviewed. Comprehensive clinicopathologic data were collected including potential risk factors related to the patient, disease, surgery and postoperative period. The patients were categorised into the group with the fistula (a study group) and without it (a control group). The incidence of the fistula was calculated and the groups were statistically compared according to potential risk factors using the Chi square test, Fisher exact test,
T
test, Mann–Whitney
U
test and binary logistic regression analysis. Hundred fifty-eight patients were included. The incidence of the fistula was 30.4 %. In the primary laryngectomy group the incidence was 22.6 %, whereas in the salvage laryngectomy group 44.6 % (
p
= 0.006). The independent predictors for the fistula were history of head and neck cancer (
p
= 0.001), invasion of piriform sinus (
p
= 0.020) and surgical wound infection (
p
< 0.001). The timing of surgical wound infection could be of some importance. In the PCF group, it started on the 5th postoperative day, whereas in the control group on the 7th postoperative day (
p
= 0.063). Decreasing the rate of surgical wound infection could diminish the fistula rate.
Abstract Background and purpose In the majority of patients irradiated for early glottic cancer an abnormal voice was reported. The purpose of the study was to determine the factors influencing voice ...quality after radiotherapy for T1 glottic cancer. Methods The voices of 75 male patients irradiated for T1 glottic carcinoma were assessed subjectively and objectively by acoustic analyses and aerodynamic measurements. The laryngeal function and morphology were evaluated by videolaryngostroboscopy. The data on smoking habits, the associated diseases influencing voice quality, the extent of the tumor, the type of biopsy, and the irradiation technique were collected from the medical records. The data on the factors influencing voice quality were compared for patients with a normal/near-normal voice and those with a hoarse voice. Results Voice quality was at least slightly abnormal in 94.7% and 81.3% of patients, when assessed perceptively and objectively, respectively. Smoking after the completed treatment, more severe morphologic alterations of the vocal folds, dryness of the throat, incomplete closure of the vocal folds and functional voice disorders expressed as supraglottic activity adversely influenced the voice quality. A good correlation between the perceptive voice assessment and the acoustic analyses was established. Conclusions After the successful irradiation for T1 glottic carcinoma, the great majority of the patients have at least a slightly hoarse voice. A better voice outcome could be achieved if radiotherapy was followed by the patient’s cessation of smoking and the appropriate voice therapy.
Intraoperative monitoring of the cranial nerve XI (CN XI) may decrease shoulder disability following modified radical neck dissection. Prospective study was designed comparing results of Constant ...Shoulder Score (CSS), Shoulder Pain and Disability Index (SPADI) and EMG score of the trapezius muscle (mT) before and after surgery. One side of the neck was monitored during surgery with intraoperative nerve monitor. EMG scores of the mT 6 months postoperatively were statistically better on monitored as compared to the non-monitored side of the neck (
p
= 0.041), while the differences of the CSS and SPADI were not statistically significant. Patients with better EMG scores of the mT at 6 weeks recuperated better and with smaller decrease of the CSS. Intraoperative monitoring is beneficial at the beginning of the surgeon’s learning curve and in the process of familiarizing with anatomical variation of the CN XI.
