Although microlaryngoscopy is an integral part of surgical routine of otorhinolaryngologists, there is no population-based data published on surgery rates and efficiency of microlaryngoscopy country-wide or nation-wide. All 616 patients who underwent microlaryngoscopy 2011 in one of the eight ENT departments in Thuringia were analyzed according to patients' characteristics, therapy, complications and follow-up. The majority of admissions were performed because of a benign disease (60%) of the larynx, and in 33% related to a malignant disease or suspicion of a malignant disease. When a benign disease was suspected, it was confirmed 98% of cases. When a malignant tumor was suspected, it was confirmed in 51% of cases, i. e. ruled out in 49% of cases. Transient laryngeal edema (22%) and bleeding needing revision surgery (1%) were the most frequent or serve observed postoperative sequelae. Teeth damage occurred only in 2 cases (0.2%). A recurrence of the primary disease was observed in 14%. Longer surgery time was an independent predictor for postoperative bleeding and for postoperative laryngeal edema (p=0.050 and p=0.013, respectively). Revision surgery (p<0.0001) and a final diagnosis of a malignant disease (p=0.017) were independent predictors for recurrence of the primary disease. The overall incidence of microlaryngoscopy was 22.98/100000 population. The highest incidence was seen for patients 50-59 years of age with 39.76/100000. Benign diseases were the most frequent indication with 19.33/100000. This population-based analysis is showing that microlaryngoscopy is performed effectively and with low postoperative risks in daily routine of otorhinolaryngologists.

Background: Although modern minimal-invasive paranasal sinus surgery is an integral part of clinical routine of otorhinolaryngologic surgeons, there are no population-based data on incidence and efficiency of this surgery published.

Material And Methods: 1,582 patients underwent paranasal sinus surgery in the 8 Thuringian departments of otorhinolaryngology in 2005. All patients were analysed regarding patients' characteristics, therapy, complications and further course of disease. Read More

Preoperative clinical predictors of difficult laryngeal exposure for microlaryngoscopy: the Laryngoscore.

Laryngoscope 2014 Nov 26;124(11):2561-7. Epub 2014 Jun 26.

Department of Otorhinolaryngology-Head and Neck Surgery, University of Brescia, Brescia.

Objectives/hypothesis: To identify a clinical predictor score for difficult laryngeal exposure (DLE) during operative microlaryngoscopy.

Study Design: Prospective cohort study in two academic institutions.

Methods: We evaluated 319 patients before microlaryngoscopy for benign and malignant glottic diseases by a standardized preoperative assessment protocol (Laryngoscore) that included 11 parameters: interincisors gap (IIG), thyro-mental distance, upper jaw dental status, trismus, mandibular prognathism, macroglossia, micrognathia, degree of neck flexion-extension, history of previous open-neck and/or radiotherapy, Mallampati's modified score, and body mass index (BMI).

Clinical value of optical coherence tomography in laryngology.

Head Neck 2008 Dec;30(12):1628-35

Department of Otorhinolaryngology, Head and Neck Surgery, Kantonsspital Aarau, Aarau, Switzerland.

Background: Optical coherence tomography (OCT) is a new, noninvasive imaging technology for the evaluation of superficial lesions. The objective of this study is to evaluate microlaryngoscopy in combination with OCT compared with microlaryngoscopy alone (ie, without OCT) in supplying a specific diagnosis, predicting invasive tumor growth and epithelial dysplasia in the larynx.

Methods: This was a prospective study including 217 laryngeal lesions in a total of 193 patients undergoing surgery. Read More
