RESUMEN
During the 2017 IFOS international congress in Paris, a roundtable discussion on the topic of functional and aesthetic rhinoplasty was organised. Five experts, from the five continents and renown in the field of rhinoplasty, were brought together to discuss the issue from an international perspective and to put forward a consensus or on the contrary practical differences. Five questions were put to the experts beforehand to guarantee independent answers, which were then discussed during the roundtable. The questions were the following: - What are the age limits for achieving a rhinoplasty? - Do you use objective measurements before, during and after surgery? (facial landmarks, airflow, peroperative measurements) - How do you manage the preoperative general information and computer imaging of the patient? - What are the indications in your practice to perform a CT-scan or endoscopic examination before doing a rhinoplasty? - What kind of graft or prosthesis do you use for an augmentation rhinoplasty? This paper offers a synthesis of the roundtable based on the experts' answers to the different questions.

Introduction. Woakes' syndrome, commonly defined as severe recurrent nasal polyps with consecutive destruction of the nasal pyramid, is rare with only a few reports in the literature documenting surgical treatment of the external nose. Case Presentation. We describe the case of an adult patient with Samter's triad who had been surgically treated from nasal polyposis since 2002. By 2014 a conspicuous deformity of the nasal pyramid had progressively occurred due to a recurrence. The patient underwent revision endoscopic sinus surgery and narrowing of the bony nasal vault by digital compression without osteotomies. Discussion. Having been described over 130 years ago, the etiology of Woakes' syndrome remains poorly understood. Treatment includes endoscopic sinus surgery and topical treatment. Surgical treatment of the external nose deformity by rhinoplasty is rarely addressed. Conclusion. This case illustrates that the widening of the bony nasal vault may be successfully corrected by digital compression, if the nasal bones are substantially thinned, in combination with surgical treatment of nasal polyps.
RESUMEN
Epidermoid cysts, dermoids, gliomas, and meningo-/encephaloceles are the most important differential diagnoses in congenital nasofrontal masses. Since they arise from an abnormal fusion during fetal development, intracranial extension of the lesion has to be ruled out radiologically before therapy. Dermoids are the most common entity. We report about a congenital epidermoid cyst of the glabella and nasion that had been growing over the last two years before presentation in a 24-year-old patient. We discuss radiological imaging and the different surgical approaches described in literature.
RESUMEN
BACKGROUND: Over the last two decades, the use of the external approach for primary and secondary rhinoplasties has become increasingly popular. This article illustrates the versatility of endonasal techniques for the correction of nasal tip deformities on the basis of four cases. PATIENTS AND METHODS: The approach to the nasal tip and the chosen technique as used in 100 consecutive rhinoplasties were reviewed. RESULTS: For primary and revision tip plasty, endonasal approaches were used in 81% of cases. Preferred incisions were the infracartilaginous approach and the transfixion incision. Using these approaches, correction of the tip was achieved by using sutures to reposition and reshape the alar cartilages and the columella without grafts to the nasal tip in most cases. CONCLUSION: Nasal tip plasty via endonasal approaches using sutures is technically more challenging compared to the external approach with its superior exposure. This drawback is outweighed by less operating time and faster patient recovery. Contrary to the general trend, the authors believe that endonasal tip plasty techniques using sutures can obviate the external approach and grafts in many cases and should form an integral part of the rhino-surgeon's repertoire.

The surgical treatment of frontal sinus fractures is foreshadowed by fears of late complications. Complications such as meningitis and mucoceles should be prevented by cranialization or obliteration of the frontal sinus. These procedures are still standard treatment despite of recent developments over the last two decades in endoscopic sinus surgery, in medical imaging and surgical instrumentation. Nowadays the role of cranialization and obliteration is challenged by refined endoscopic frontal sinus surgery techniques, the widely-used image-guided systems and the multiplanar high-resolution computed tomography along with new data about postoperative complications. This overview summarizes the current literature, taking into account the existing evidence in the treatment of frontal sinus fractures.

Endoscopic forehead lifting is a widely accepted treatment for brow ptosis. The procedure safely and effectively corrects horizontal forehead rhytids, brow ptosis, upper eyelid dermatochalasis and periorbital crow's feet. The result is a refreshed and more open facial expression. A thorough understanding of basic facial anatomy is the key to successful cosmetic surgery. The procedure is based on a subperiostal and preperiosteal mobilisation of the temporal and frontal soft tissues and a detachment of the periosteum of the orbital rim. An upper eyelid blepharoplasty and selective incomplete or complete myotomies of the corrugator and procerus muscles may be incorporated in the operation. Most surgeons prefer to fixate the elevated soft tissue planes to the calvarium by sutures, titanium or resorbabale polyglactid anchors. While initial enthusiasm for this procedure seems to be declining in several countries, few ENT-surgeons are familiar with this technique in Europe. This article reviews the surgical anatomy of the forehead and temporoparietal region by means of cadaver dissection and describes the surgical procedure for German speaking readers.

BACKGROUND: There can be many differences between the clinical presentation and disease development of endocrine orbitopathy. Uncommon clinical expressions of the disease may lead to misinterpretations causing difficulties in treatment. Misdiagnosed forms of the disease can end with irreversible vision loss. PATIENTS: A 79-year old female with severe bilateral thyroid eye disease, progressive almost blinding visual loss, with the absence of exophthalmos is described. Second, a 39 year old female with a unilateral thyroid eye disease and relapsing episodes of the disease is reported. DISCUSSION: Exophthalmos, as a symptom, occurs in about 60 % of the patients diagnosed with thyroid eye disease. The absence of exophthalmos may be due to a reduced volume (atrophy ) of retrobulbar fat tissue. Progressive visual loss can be related to direct compression of the optic nerve by thickened eye muscles in the orbital apex. Thyroid eye disease presents itself unilaterally in 5-11 % of all cases and involvement of the contra lateral orbit may occur years later. A relapse of the disease may be triggered by episodes of hypo- or hyperthyroidism. Smoking is a significant risk factor for orbitopathy relapse. CONCLUSIONS: Physicians treating thyroid eye disease should be aware of atypical clinical presentations in order for early satisfactory treatment. An interdisciplinary approach including ophthalmologists, endocrinologists and oto-rhino-laryngologists is necessary for optimal management.

BACKGROUND: Exact estimation of a tumor's size and the definition of adequate resection margins in carcinomas of the tongue are often difficult because of the tumor's extension and deep infiltration. METHODS: We have developed a method that allows intraoperative visualisation and marking of tumor margins. Intra-operative endosonography was performed on nine patients with carcinomas of the tongue using a 8-12 MHz linear array transducer. The oral cavity was flooded with normal saline solution and the transducer was immersed therein. This allowed scanning in a non-contact mode. The tumor margins were marked with a surgical suture under endosonographic monitoring. RESULTS: In the nine patients studied, the histological margins corresponded to the sonographic margins. The sonographic marking proved to be useful during the resection of the tumor and histological safety margins were respected in each case. CONCLUSIONS: This non-invasive procedure provides a quick and reliable orientation during the resection of tongue carcinoma, and a more precise and individual definition of resection margins is possible. Intraoperative non-contact use of endosonography is a promising method.

Nasal obstruction may be caused by individual anatomy, a dysregulation of the nasal mucosa or, frequently, a combination of both. Persistent allergic inflammation deserves special attention, as initial therapy should not be surgical. The plethora of surgical techniques for the reduction of inferior turbinate volume is a good indicator of unresolved controversies regarding the ideal technique. This review analyses our current knowledge about success and complication rates of different surgical techniques. Many of these techniques have a distinct pro and contra-profile which is acceptable for both the patient and the surgeon. This is a good starting point for randomised clinical trials. The definition of the anterior turbinoplasty as a gold-standard for future trials is proposed.

The amorphous or wide nasal tip is the most commonly encountered nasal tip deformity, but little has been done to measure the effect of standard rhinoplasty techniques on nasal tip width. In the clinical routine, nasal tip width and soft-tissue cover thickness are estimated by inspection and palpation rather than by measurement. In this study, a B-mode sonograph with a 12-MHz transducer was used in a noncontact mode to measure tip width 0.5 cm occipital to the tip defining point, distance between the alar cartilage domes, and thickness of the soft-tissue cover overlying the lower lateral cartilages. These parameters were measured 3 to 8 weeks before and 56 days to 19 months after a transdomal suture tip plasty in 18 patients. The distance between the alar cartilage domes seemed to be an important factor for tip width because interdomal distance, not soft-tissue cover thickness, correlated with tip width before surgery (correlation: 0.53). Conversely, the degree of tip refinement correlated with preoperative soft-tissue cover thickness (correlation: 0.75), but not with interdomal distance. Ultrasonic imaging of nasal soft tissues may help to assess the effect of different tip refining procedures and other soft-tissue changes after rhinoplasty.

BACKGROUND: Antibiotic impregnation of cartilage implants may reduce the risk of bacterial infection and subsequent absorption. The aim of this study was to investigate the penetration kinetics of two quinolone antibiotics into fresh cartilage and the concentrations in the core of lyophilized cartilage after rehydration. METHODS: Fresh human costal cartilage was impregnated with ofloxacin and ciprofloxacin (2 mg/ml) for 2, 15 and 90 min. Concentrations were measured in 6 levels (0.5 mm each) from the surface to 3 mm beneath the surface with high performance liquid chromatography (HPLC). Lyophilized human costal cartilage was rehydrated in ofloxacine and ciprofloxacine solutions (2 mg/ml, 0.2 mg/ml and 0.02 mg/ml) for 18 hours and concentrations in the core of the rib segment were measured. RESULTS: Quinolone antibiotics penetrate into cartilage by free diffusion. We found no evidence of significant binding to cartilage. After 2 and 15 min of impregnation, concentrations above the minimal inhibitory concentration (MIC90) for pseudomonas species are found from 0-0.5 mm below the surface of fresh cartilage. After 90 min concentrations above the MIC90 were found 1.0-1.5 mm below surface of the implant. In lyophilized rib grafts which were rehydrated in 1/10 diluted intravenous solutions (0.2 mg/ml), concentrations in the core of the specimen were above MIC90. Differences between the penetration characteristics of ofloxacine and ciprofloxacine were minor. CONCLUSION: Intraoperative impregnation of cartilage implants with ofloxacin or ciprofloxacin probably offers only short-term protection against bacterial infection. Rehydrated rib grafts, however, contain high quinolone concentrations which may be effective even in infected implant beds for several hours.

A new method using B-mode and power-Doppler-mode (pD) sonography for the investigation of changes in nasal mucosa swelling and perfusion was developed. The effect of naphazoline (0.25 mg/mL) on the nasal mucosa was visualized and recorded in 1-minute intervals in 40 patients. The effect of normal saline solution was studied in 27 healthy volunteers. The decongestant and normal saline were applied by flooding the anterior nasal cavity. A computer program automatically quantified pD color information. Normal saline solution induced a 4.8 +/- 2.4% increase in perfusion (+/- SEM, n.s.) after 5 minutes. In the naphazoline group, changes in stereometry were measured on B-mode-sequences in 24 (60%) and perfusion changes in 24 participants (60%). In 16 of 40 patients (40%), both stereometry and perfusion were analyzed. After 10 minutes, the septum and inferior turbinate mucosa thickness were reduced by 17 +/- 2.8% (p < 0.001) and 25 +/- 2.6% (p < 0.001). Perfusion of the septum and inferior turbinate mucosa as visualized with pD-sonography decreased by 33 +/- 3.3% (p < 0.001). The reduction of bloodflow induced by naphazoline as visualized with pD-sonography is within the range of perfusion changes found in LDF and Xenon clearance studies. Decongestion of the septum mucosa demonstrates erectile properties of the septum, which may contribute to the increase of nasal patency after nasal decongestion.

The reliability of skin prick tests (SPT) may be insufficient for the screening of occupational inhalant allergies. The influence of different flour extracts on the SPT in flour allergic subjects has not been compared previously. In this study, SPT reactions against two commercially available rye and wheat flour extracts and individually prepared extracts from flour samples were compared in 35 patients with known bakers' rhinitis. Flour sensitization was confirmed by a positive nasal provocation test (NPT) and/or serum-specific IgE. The sensitivity of NPT with a combination of rye and wheat flour extracts of individual flour samples was 94%. Wheat and/or rye flour specific IgE (RAST>/=2) was true positive in 86%. The sensitivity of the SPT was 94% for individual rye flour extracts compared to 38% and 59% for two commercially available rye flour extracts and 88% for individual wheat flour extract compared to 53% and 48% for commercially available wheat flour extracts. SPT and sIgE did not reveal a significant difference in prevalence between rye and wheat flour sensitization. Thirty healthy volunteers served as the control group. Three control subjects with histamine equivalent SPT reactions to grass pollen had a positive SPT reaction against individual flour extracts, whereas NPT with undiluted individual flour extracts was negative in all controls. SPT with individually prepared flour extracts appears to be sensitive for the demonstration of inhalant flour allergy. Our findings show that extracts of individual flour samples rather than commercially available extracts should be used for both SPT and NPT if flour allergy is suspected.

The diagnosis of cystic echinococcosis (echinococcus granulosus) in an atypical location can be difficult to make and frequently can only be established by histological examination of affected tissues. Surgical excision and fine-needle aspiration biopsy usually lead to the diagnosis. Since puncture of these cysts may cause an anaphylactic reaction due to spillage of hydatid fluid and/or dissemination of infection, the use of fine-needle aspiration biopsy is controversial at present. We report on a patient with a cystic neck mass who developed an allergic reaction after diagnostic fine-needle aspiration biopsy. Cytological examination of the specimen was inconclusive. The allergic reaction led to the diagnosis of echinococcosis, which was confirmed by serological examination. We describe a possible diagnostic procedure for a cystic mass of unknown etiology. If imaging and serological tests are not conclusive, we believe that fine-needle aspiration biopsy is justified. However, this should only be performed in a setting that provides sufficient management for anaphylactic reactions.

Endoscopic and video-endoscopic visual acuity and color discrimination were investigated using a standard disk for testing visual acuity and a color discrimination test. A 1-chip-CCD-Camera (CCC) or 3-chip-CCD-Camera plus digital image processing (digivideo) on the endoscope and a 15 inch high resolution video monitor were used. Color discrimination was investigated by comparing the ability to sort colored disks of low chromatic saturation (desaturated Panel D-15 Test), ranging from yellow to red, under direct vision or via monitor using the same 1-CCC- and 3-CCC-system. Visual acuity deteriorated by 1.58 +/- 0.16 steps (+/- SEM) for the 1-CCC and 1.21 +/- 0.16 steps for the 3-CCC plus digivideo compared to vision through the endoscope (p < 0.001 and p < 0.001). Visual acuity was significantly better for the 3-CCC-video-endoscope compared to the 1-CCC-video-endoscope (p = 0.0045). The difference in color discrimination between the naked eye and the 1-CCC-monitor system was not significant. More mistakes were made with the 3-CCC-monitor system. The impairment of image quality with the video endoscope, which is experienced by many surgeons, is reflected in a marked loss of visual acuity in our experiments. Sharpness and contrast of the video-image are significantly enhanced by the 3-CCC plus digital image processing, compared to the 1-CCC. Color discrimination, however, was not impaired by the 1-CCC, indicating that color perception with the video-endoscope can be very good and may not contribute significantly to the loss of image quality.

PURPOSE: To evaluate the relative value of magnetic resonance (MR) imaging versus computed tomography (CT) in the diagnosis of inflammatory paranasal sinus disease. MATERIALS AND METHODS: In 30 patients suspected of having or known to have inflammation of the paranasal sinuses, both coronal CT and coronal T1-weighted, three-dimensional, gradient-echo MR imaging of the paranasal sinuses were performed. Visualization of anatomic details, kind and extent of inflammatory disease, and artifacts from dental work were scored. The scores were compared by using the Wilcoxon matched pairs signed rank test. Interexamination agreement between the two methods was calculated by using a kappa analysis. RESULTS: Most bone structures of the infundibular complex were significantly better visualized at CT than at MR imaging. Orbital and brain anatomy were visualized better at MR imaging than at CT. No artifacts from dental work occurred in diagnostically relevant regions at MR imaging. There was a substantial to almost perfect agreement between CT and MR imaging for every kind and extent of the disease except for mucosal thickening in the maxillary and frontal sinuses, in the nasal cavity, and in the infundibulum. CONCLUSION: CT is superior to MR imaging in the depiction of fine bony details and anatomic variants and thus is superior to MR imaging in helping plan functional endoscopic sinus surgery. However, there are patient groups in which MR imaging can be used as a primary tool in screening for sinusitis.
