The holmium:YAG laser lithotripsy-a non-invasive tool for removal of midsize stones of major salivary glands.

Incorporeal lithotripsy by using holmium:YAG laser has been recently successfully spread and used in the treatment of urolithiasis. Although this method is not as common in salivary gland surgery, it is also recommended for endoscopic treatment of sialolithiasis. In this study, we decided to analyse effectiveness of holmium:YAG laser method among patients with midsize stones as the treatment in this particular population is still not determined and remains in dispute. Thus, the primary aim of the study is a prospective, complex analysis of incorporeal holmium:YAG laser lithotripsy effectiveness and safety in patients suffering from sialolithiasis. The examined group consisted of 32 consecutive patients, 17 female (53%) and 15 male (47%). The average age was 42 (age range 22-70). In our series, sialoendoscopy with intraductal lithotripsy was performed in patients with wide range of stone's diameter (3 to 10 mm). The calculi were removed with foreign body forceps or retrieval basket, after stone fragmentation with holmium:YAG laser. The power of the laser during surgery was set at 2.5 to 3.5 W. One shot energy equalled 0.5-0.7 J with frequency of 5 Hz. The bivariate Pearson Correlation and a point-biserial correlation were used to analyse the data. Total success rate of holmium:YAG laser lithotripsy in this consecutive group was equal to 90% and efficacy in the group with excluded cases when endoscopic approach difficulties were experienced (stone not visible) reached 93%. The long-term follow-up revealed that in 26 patients (84%), complete recovery was achieved. Two patients developed Wharton's duct stenosis and one Stensen's duct orifice stenosis (9.5%), of whom one required reoperation. Two patients eventually underwent total excision of submandibular gland. Sialoendoscopy combined with incorporeal laser-assisted lithotripsy proved to be effective and safe method for treatment of sialothiasis with midsize stones (4-8 mm) in population of clinic. Even taking into account the prevalence of complications associated with holmium:YAG laser, it is still safer alternative compared to open surgery where there is a significant risk of the bleeding, wound infection or injury of the facial nerve.

The Knowledge of the Role of Papillomavirus-Related Head and Neck Pathologies among General Practitioners, Otolaryngologists and Trainees. A Survey-Based Study.

OBJECTIVES: The aim of the survey was to introduce knowledge of HPV's role in head and neck pathologies to general physicians (GPs), otorhinolaryngologists (ENTs) and newly graduated doctors, as well as to promote HPV-related diseases prevention. STUDY DESIGN: Cross-sectional study. METHODS: Self-designed questionnaire was sent to 2100 doctors. A total of 404 doctors, including 144 ENTs, 192 GPs and 68 trainees, responded. RESULTS: The majority of ENTs (86.8%) had contact with recurrent respiratory papillomatosis (RRP) and oropharyngeal cancers (OPCs) patients; in contrast, the majority of GPs (55.7%) did not (p = 0.00). The knowledge of HPV aetiology of cervical cancer versus OPCs and RRP was statistically higher. 7% of ENTs, 20% of GPs and 10% of trainees had not heard about HPV in oropharyngeal diseases. Women had greater knowledge than men. Both in the group of GPs and ENTs, 100% of respondents had heard about the impact of vaccination on the reduction of cervical cancer incidence. Only 39.11% of respondents had heard about the possibility of using vaccination against HPV in RRP-ENT doctors significantly more often than GPs and trainees (p = 0.00). Only 28.96% of physicians had heard about the potential value of HPV vaccination in preventing OPCs, including 44.44% of ENT doctors, 23.44% of GPs and 11.76% of trainees (p = 0.00). The doctors from district hospitals showed lower level of knowledge compared with clinicians (p = 0.04). CONCLUSIONS: The different levels of knowledge and awareness of HPV issues highlight the need for targeted awareness strategies in Poland with implementation of HPV testing and vaccination. The information should be accessible especially to those with lower education levels: ENTs from small, provincial wards, GPs from cities of < 200,000 inhabitants and older physicians. The incorporation of HPV issues into the studies curriculum would be fruitful in terms of improving the knowledge of trainees.

Adverse histopathological findings in glottic cancer with anterior commissure involvement.

Open partial horizontal laryngectomy (OPHL) specimens include cartilage and lymph nodes. Pathological adverse findings (PAF): perichondrium, cartilage, perineural invasion, microvessel spread and prelaryngeal metastases can be detected histologically. We aimed at examining PAF in OPHL specimens and examining the interdependence with oncological outcomes. Prospective analysis of 254 glottis cancers: 87-T2a, 77-T2b and 90-T3 with anterior commissure (AC) involvement treated by OPHL at tertiary referral centre between 2001 and 2008. In 38/254 patients (15 %) PAF were found (16 prelaryngeal metastases, 22 other); more often in stage T2b/T3 versus T2a (p = 0.008). PAF other than prelaryngeal metastases were found more often in T2b than T2a tumours (p = 0.005). Outcomes revealed that out of 36 patients with local recurrence, 19 had PAF. Comparison of 216 patients with no PAF and 16 patients with prelaryngeal metastases revealed, respectively: 7.9 versus 81.3 % local recurrences (p = 0.034), 3.2 versus 68.8 % nodal recurrences (p = 0.011), 90.7 versus 43.8 % of 5-year organ preservation (p = 0.021) and 92.6 versus 75 % 5-year overall survival (p = 0.022). Out of 10 patients with close margins, 1 developed the local recurrence; impact for organ preservation and overall survival was not significant. In 22/254 cases including the cartilage into the operating specimen were therapeutically meaningful; in 16/254 with prelaryngeal metastases, the impact for larynx preservation and overall survival was significant. T2b patients had higher probability of PAF than T2a. PAF significantly influenced higher local recurrence rate. This finding ensures the authors, that OPHL type II is not the "overtreatment" compared to the TLM.

Attempt to improve functional outcomes in supracricoid laryngectomy in T2b and T3 glottic cancers.

The goal of this study was to compare the survival rate and functional outcome of an open partial horizontal laryngectomies, Type IIa and modified Type IIa (OPHL Type IIa and OPHL mType IIa), in treatment of moderately advanced glottic carcinoma. Retrospective analysis. 80 Patients underwent OPHL Type IIa and 27, OPHL modified Type IIa (OPHL mType IIa) between the years 2001 and 2009. Clinical staging was performed according to the UICC criteria (2002). Primary endpoints of study were recurrence rate, and 3- and 5-year survival time. Secondary endpoints were laryngeal functions: respiration, swallowing and voice. There were no significant differences within local and regional recurrence rates, organ preservation rate, 3- and 5-year specific disease survival rates between OPHL Type II and OPHL modified Type IIa. Significantly lower need for temporary (OPHL mType IIa 4/27, OPHL Type IIa 30/80) and permanent tracheostomy (OPHL mType IIa 2/27, OPHL Type IIa 16/80) was found. All but one patient (OPHL Type IIa) achieved unrestricted diet. Significantly differed social eating, this ability gained 25/27 OPHL mType IIa and 54/80 OPHL Type IIa (p < 0.05). Voice handicap index revealed a decrease in quality of life in all areas; OPHL Type IIa and OPHL mType IIa differed significantly (31 and 46 points respectively, p < 0.005). The MPT value (longest pitch) for OPHL Type IIa and OPHL mType IIa lasted 8 s and 10, respectively (p < 0.005). There was no significant difference in oncological outcomes between the two types of OPHL succeeded in the earlier extubation, thus significantly lowering the need for temporary and permanent tracheotomy and providing better long-term swallowing. Although the voice was altered in all observed OPHL patients, modified Type IIa technique proved to be superior to the Type IIa in terms of voice quality. Thus, OPHL modified Type IIa is worth promoting, as long as indications were strictly conformed.

[Influence of tendon surgery training on the quality of the suture]. / Wplyw treningu zespalania sciegien na jakosc zalozonego szwu.

Injuries of flexor tendons are one of the most common injuries that need surgical treatment at emergency room. Technique and quality of the surgery was performed are two factors of the utmost importance. The aim of the study was to determine influence of basic surgical training on the quality of suture. Research was divided into four surgical sessions which were held each once a week. Sutures were put by three medical students. Material that was used were deep flexor tendons dissected from fresh pig's legs. Sessions 1st, 2nd and 4th were preceded by training done by experienced surgeon. During study 90 modified-Kessler sutures without additional running suture were made. Breaking strength was assesed by tensile machine (INSTRON 4481). Time of each suture was also recorded. Outcomes were analyzed by tests: ANOVA and post-hoc LSD tests. Time significantly dropped by 64% after the first session and was held on the same level. Strength of sutures rises in each session preceded by training. There was statistically significant difference between session 1 (mean 13.58; SD 9.86N) and 2nd (mean 42.69; SD 9.27N) and 3rd (mean 38.42; SD 12.28N) and 4th (mean 57.12; SD 12.78N). Conclusions. Time of procedure significantly dropped after first teaching course and was held on the same level despite further training. Breaking strength rise in every session that was preceded by teaching course.
