[Nasal hemorrhage - risk factors and management in 707 outpatient and inpatient patients]. / Epistaxis ­ Risikofaktoren und Management bei 707 ambulant und stationär geführten Patienten.

Epistaxis is one of the most common emergencies in otorhinolaryngology. The spectrum ranges from mild, self-limiting cases to life-threatening hemorrhages. Depending on the severity and course of the condition, management can be either outpatient or involve inpatient monitoring, possibly with surgical treatment.A retrospective systematic evaluation was conducted on all outpatient and inpatient patient data diagnosed with epistaxis from January to December 2021. Epistaxis associated with tumors, trauma, and postoperative epistaxis were excluded.A total of 707 patients were included. Seasonally, the highest number of patients presented in January. Outpatient management was possible for 80.8% of the cases, while 19.2% required inpatient admission. Among the inpatients, 15.4% required surgical intervention. Within the entire study cohort, 61.1% of the patients were male. Among the inpatients who underwent surgical treatment, the proportion of male patients was even higher (81.0%). The majority (73.1%) of the inpatients were on at least one anticoagulant medication. Advanced age (p=0.044) and the presence of posterior epistaxis (p<0.001) were significantly associated with the need for inpatient treatment. No children required inpatient care.Epistaxis is a common condition in otorhinolaryngology, predominantly affecting older male patients and those on anticoagulant therapy in severe cases within the studied cohort. Surgical intervention under general anesthesia was infrequently necessary for the treatment of epistaxis in the overall study population (3%).

The disrupted molecular circadian clock of monocytes and macrophages in allergic inflammation.

Introduction: Macrophage dysfunction is a common feature of inflammatory disorders such as asthma, which is characterized by a strong circadian rhythm. Methods and results: We monitored the protein expression pattern of the molecular circadian clock in human peripheral blood monocytes from healthy, allergic, and asthmatic donors during a whole day. Monocytes cultured of these donors allowed us to examine circadian protein expression in human monocyte-derived macrophages, M1- and M2- polarized macrophages. In monocytes, particularly from allergic asthmatics, the oscillating expression of circadian proteins CLOCK, BMAL, REV ERBs, and RORs was significantly altered. Similar changes in BMAL1 were observed in polarized macrophages from allergic donors and in tissue-resident macrophages from activated precision cut lung slices. We confirmed clock modulating, anti-inflammatory, and lung-protective properties of the inverse ROR agonist SR1001 by reduced secretion of macrophage inflammatory protein and increase in phagocytosis. Using a house dust mite model, we verified the therapeutic effect of SR1001 in vivo. Discussion: Overall, our data suggest an interaction between the molecular circadian clock and monocytes/macrophages effector function in inflammatory lung diseases. The use of SR1001 leads to inflammatory resolution in vitro and in vivo and represents a promising clock-based therapeutic approach for chronic pulmonary diseases such as asthma.

[Functional disorders of the nose - definition, diagnostics and treatment options]. / Funktionelle Formstörungen der Nase ­ Definition, Diagnostik und Therapieoptionen.

The surgical spectrum of functional rhinosurgery includes nasal septum surgery, septorhinoplasty and nasal concha surgery. Based on the German guideline "Disorders of the inner and/or external nose (with functional and/or aesthetic impairment)" published in April 2022, which was prepared on behalf of the German Society of Otorhinolaryngology, Head and Neck Surgery, we discuss the indications, diagnostic approaches, the planning of the surgery and postoperative care. The most common findings of the external nose with a functional impairment include crooked nose, saddle nose, and tension nose. Combined pathologies occur. Well-documented in-depth consultation is essential for rhinosurgical procedures. In the case of revision surgery, the possible necessity of autologous ear or rib cartilage should be considered. Despite correct surgical performance, no "guarantee" can be given for the surgical (long-term) result in rhinosurgery.

[Importance of machine blood count in the diagnosis of infectious mononucleosis by EBV]. / Stellenwert des maschinellen Blutbildes bei der Diagnose der infektiösen Mononukleose durch EBV.

INTRODUCTION: EBV serology is recommended for serological diagnosis of mononucleosis. As results of an automated differential blood count is available more quickly, possible differences between an EBV primary infection and a bacterial tonsillitis were investigated. METHODS: A retrospective evaluation of absolute and relative lymphocyte and monocyte counts of n = 140 patients > 16 years from 01/2008 to 01/2019 (mean age 21.4 years, 51 % ♀, 49 % ♂) with suspected EBV infection was performed. The groups of a serologically confirmed or excluded EBV infection were compared. RESULTS: An automated differential blood count was available in n = 42 patients with primary EBV infection. Average lymphocyte count was 5.5 ±â€Š2.6 giga/l. Patients with acute bacterial tonsillitis (n = 36) had significantly lower values with 1.6 ±â€Š1.3 giga/l, p < 0.05. Equal results were found in relative lymphocyte counts (47.4 ±â€Š17.9 vs. 12.8 ±â€Š9.1 %, p < 0.05). For monocyte counts, neither absolute (1.2 ±â€Š0.8 vs. 1.2 ±â€Š0.6 giga/l, p = 0.617) nor relative (8.8 ±â€Š3.6 vs. 9.8 ±â€Š5.2 %, p = 0.746) monocyte counts showed significant differences. CONCLUSION: Increased lymphocyte counts in an automated differential blood count can be a first indication of primary EBV infection. Perhaps up to 30 % morphologically altered lymphocytes are increasingly counted correctly with modern hematology analyzers and no longer counted as monocytes. These results could be used to make decisions about further diagnosis (abdominal ultrasonography, ECG) and antibiotic therapy before results of EBV serology are available.

Symptom Control of Patients With Chronic Rhinosinusitis With Nasal Polyps Under Maintenance Therapy With Daily Acetylsalicylic Acid.

INTRODUCTION: Nonsteroidal anti-inflammatory drugs (NSAID)-exacerbated respiratory disease (NERD) is defined by intolerance to cyclooxygenase 1 inhibitors, chronic rhinosinusitis with recurrent nasal polyps, and/or intrinsic bronchial asthma. Long-term administration of acetylsalicylic acid (ASA) after desensitization has been used to mitigate these sequelae, but the optimal dose and balancing symptom relief and side effects remain unsettled. METHODS: Retrospective data analysis of 85 patients with NERD receiving maintenance therapy of 300 mg ASA was followed by questionnaires (our own, not validated and the Sino-Nasal Outcome Test-20). We received responses from 55 patients and examined 30 of them clinically. RESULTS: Patients with no ASA-associated side effects were 56.4% (56 of 85 patients) of the cohort. In this study, 60% (33 of 55 patients) continued prophylaxis of 300 mg ASA daily for an average of 34.7 months. Elective surgery was the most frequent cause of discontinuation of ASA (21.8%; 12 of 55 patients). Rhinomanometry values were significantly improved with ASA (P < .05; Wilcoxon), but there was no significant reduction in nasal polyposis or improvement in olfaction at the time of follow-up examination. CONCLUSIONS: Minor clinical improvements were identified. Side effects were well tolerated by most patients, and no serious sequelae occurred. The indications for long-term ASA therapy in NERD patients remain unsettled.

[The KINDL questionnaire for assessment of general quality of life in adenotonsillar hyperplasia]. / Der KINDL-Fragebogen zur Erfassung der allgemeinen Lebensqualität bei adenotonsillärer Hyperplasie.

BACKGROUND: There are few systematic studies on the general quality of life of children before and after adenoidectomy and adenotonsillotomy, although interventions on adenoids and tonsils are the most frequent operations in childhood in Germany. For this reason, the established KINDL questionnaire was used to assess the quality of life of children for the first time. METHODS: Study participants (n = 111) and a waiting design control group (n = 35) were recruited consecutively from children (3-6 years) receiving adenoidectomy (66 %) or adenotonsillotomy (34 %). The Kiddy-KINDL® questionnaire was answered by parents on the day of surgery and 3.5 months postoperatively. Parents of the control group were interviewed, when the date of operation was scheduled and on the day of operation. RESULTS: Total scale score of the Kiddy-KINDL of max. 100 points improved slightly in the intervention group from preoperatively 75.9 ±â€Š10.8 (95 %-KI [73.8-77.9]) to postoperatively 77.2 ±â€Š9.2 points (95 %-KI [75.1-79.0]; p = 0.365). Also in the comparison group there was no significant change over time (77.9 ±â€Š9.7; 95 % CI [74.1-81.7] vs. 77.3 ±â€Š11.3; 95 % CI [72.8-81.8]; p = 0.949) or compared to the preoperative score of the intervention group (p = 0.894). The subscales scores for "physical well-being" (p < 0.01), "school" (p = 0.034) and "parents" (p < 0.01) showed significant improvements for the intervention group. Children with additional tonsillotomy also showed a significant postoperative increase of the total scale score (p = 0.049). CONCLUSION: The version of the Kiddy-KINDL we used is therefore not fully suitable for recording the general QOL in adenotonsillar hyperplasia, since an improvement in QOL could only be recorded in subscales. However, since tonsillotomy in particular seems to have a relevant influence on QOL, it should be performed in children with significant hyperplasia.

Incidence of anatomical variations according to the International Frontal Sinus Anatomy Classification (IFAC) and their coincidence with radiological sings of opacification.

BACKGROUND: The endonasal access to the frontal recess and sinus may be complicated by a variety of anatomical variations. Previous classifications of these variants were characterized by proper names or position information without anatomical reference. The IFAC is intended to simplify the classification of anatomical variations of the frontoethmoidal complex. The aim of this study was to analyse a representative number of sinus CT scans to assess the incidence of anatomical variations according to the IFAC and to compare the results with previous classifications. In addition, the coincidence of complex anatomical variations and radiological sings of opacification was investigated. METHODOLOGY/PRINCIPAL: Two hundred and forty-nine sinus CT scans were analysed in multiplanar reconstructions. Exclusion criteria were previous operations on the paranasal sinuses, malignant diseases, and an insufficient image quality. All anatomical variants were analysed according to the IFAC criteria. In addition, the coincidence of radiological sings of opacification and the presence of anatomical variations of the frontal recess and sinus were investigated. RESULTS: The analysis revealed Agger nasi cells in 95% of the CT scans. Supra agger cells (SACs) were detected in 49% and Supra agger frontal cells (SAFCs) in 25% of the data sets. Suprabulla cells (SBCs) were detected in 89% and Supra bulla frontal cells (SBFCs) in 27% of the scans. Supraorbital ethmoid cells (SECs) were detectable in 9% and interfrontal septal cells in 28% of the scans. Despite a partially strong narrowing of the frontal recess, no increased occurrence of radiological sings of opacification could be detected (p > 0.05). CONCLUSIONS: Anatomical variations in the frontoethmoidal area are very common. According to the IFAC criteria, in 43% of the patients, cells could be detected with pneumatization to or into the frontal sinus. The IFAC is structured more clearly compared to previous classifications due to the anatomical aspect. It represents the most consistent classification regarding surgical planning. Further studies will demonstrate the scientific and clinical value of this classification.

[Analysis of facial asymmetry in patients with crooked noses]. / Analyse von Gesichtsasymmetrien bei Patienten mit Schiefnasen.

BACKGROUND: Surgical management of crooked nose is challenging even for experienced rhino surgeons, although numerous techniques for correction have been described. Not infrequently, there is a facial asymmetry in addition to the crooked nose influencing the aesthetic results of the operation. Therefore, the purpose of this study was to determine how often there is an asymmetry of the face in addition to a crooked nose. MATERIAL AND METHODS: Retrospectively the data of 607 patients with a crooked nose (304 women, 303 men, mean age 30 years) were evaluated. The preoperative photos of the face were anthrometrically assessed based on angle measurements. RESULTS: 382 of the 607 patients had a c-shaped (63 %) and 225 an i-shaped (37 %) crooked nose. More than three-quarters of the patients had facial asymmetry in respect to the connecting line of the pupils and nasal base line. 49 % of patients reported a history of nasal trauma, but this had no relevant influence on the frequency of facial asymmetry. CONCLUSIONS: Pre-existing facial asymmetry is very common in patients with crooked nose and can significantly affect the aesthetic outcome of nasal surgery. This should be addressed as part of the informed consent. In particular, it should be mentioned that the surgical outcome can remain below the patient's aesthetic expectations. Not rarely, a revision surgery may be necessary.

[Symptoms and parental expectation in adenoidectomy and adenotonsillotomy in preschool children]. / Hauptsymptome und Elternerwartung bei Adenotomie und Adenotonsillotomie im Vorschulalter.

OBJECTIVE: In this study, symptoms associated with adenoids and hyperplasic palatine tonsils and parental expectation of surgical outcome were recorded, to provide realistic parental information prior to adenoidectomy (AT) ± tonsillotomy (ATT). MATERIAL AND METHODS: In total n = 111 children (3-6 years, ♂ 65 % ♀ 35 %) were recruited, who received AT (66 %) or ATT (34 %) at ENT University Hospital Ulm. By questionnaire-based survey, the most common symptoms and the main reason for the operation were reported from parent's perspective (operation day, follow-up: 3.5 months). Results were visualized in bar charts for total collective and AT and ATT surgical groups (significance level α = 5 %). RESULTS: Most commonly, parents observed signs of respiratory problems (mouth breathing 87 %, nasal obstruction 86 %, snoring 78 %), hearing loss (68 %) and infection of upper airways (66 %). Nasal obstruction (77.5 %) and hearing loss (53.2 %) were the main reasons for operation. In children with pharyngeal tonsil hyperplasia only, hearing problems dominated, while in additional tonsillotomy, nocturnal apneas were the most frequently reported reason for surgery. For all symptoms, a significant postoperatively improvement was achieved. CONCLUSIONS: With a differentiated indication for surgery, it is possible to inform the parents about a very good and realistic and effective reduction of symptom after AT and ATT.

Surgery of Anterior Skull Base Lesions in Children.

INTRODUCTION: Lesions affecting the anterior skull base represent a rare group of craniofacial pathologies. A tumor of the facial midline, meningitis, or rhinoliquorrhea may be indicative of malformations like dermoid cysts, gliomas, encephaloceles, or nasal fistulas. METHODS: We present a case series of 13 children (4 months to 12 years; 8 males, 5 females) with lesions involving the anterior skull base, which were treated surgically in an interdisciplinary setting. This case series includes cases of nasal fistulae (n = 5), nasal cysts (n = 5), aneurysmal bone cyst, nasal glioma, and meningoencephalocele (n = 1). RESULTS: All lesions were resected with a transnasal, transcutaneous, and/or transcranial approach with reconstruction of the anterior skull base if intracranial/intradural extension was detected. In 5 cases, a dura leakage was visible, which was sealed via Onlay-technique in 3 cases, whereas in 2 cases involving a greater dural defect, the GAP-CAS technique was performed. No complications occurred, and no recurrence was visible in a long-term follow-up. An algorithm for a systematic approach to these various pathologies is provided. CONCLUSION: Congenital pathologies of the anterior skull base are rare, challenging to diagnose, and present as clinical emergencies. An interdisciplinary surgical approach is needed for best functional and aesthetic results.

Three different turbinoplasty techniques combined with septoplasty: Prospective randomized trial.

OBJECTIVES/HYPOTHESIS: Septal deviation and hypertrophic inferior turbinates are a frequent cause of nasal breathing disorders. The goal of this study was to prove the effectiveness and safety of three current turbinoplasty techniques. STUDY DESIGN: This is a prospective, three-arm, single-blinded, single-center, randomized controlled trial. METHODS: Sixty patients were randomly assigned to either anterior turbinoplasty (ATP) (n = 20), radiofrequency ablation (RFA) (n = 19; Celon Pro Breath), or novel submucous radial diode laser ablation (DLA) (n = 21; ELVeS Radial PainLess, wavelength = 1,470 nm), each in combination with standard septoplasty. Acoustic rhinometry, rhinomanometry, subjective nose questionnaire, and saccharin test served as outcome parameters for preoperative and 3-month, 1-year, and 2-year postoperative examinations. RESULTS: After 3 months 47/60 patients were evaluated, 28/60 patients were evaluated after 1 year, and 26/60 patients were evaluated in the 2-year follow-up visit. An improvement of nasal breathing was observed in all three groups in all follow-up visits. The increase of endonasal volume 2 (volume between the nasal valve and body of the inferior turbinate) was statistically significant in the ATP and RFA group after 3 months and 2 years, and in the RFA group also after 1 year. The DLA group failed to reach significance level in all follow-up visits. Subjective evaluation of nasal breathing improved in all three groups. CONCLUSIONS: In this trial, three different current techniques of turbinate surgery in combination with standard septoplasty were effective for the improvement of nasal breathing. The ATP and RFA techniques were more effective in the long term than DLA. LEVEL OF EVIDENCE: 1b. Laryngoscope, 2016 127:303-308, 2017.

Numerical simulation of humidification and heating during inspiration in nose models with three different located septal perforations.

Nasal septum perforations (SP) are characterized by nasal obstruction, bleeding and crusting. The disturbed heating and humidification of the inhaled air are important factors, which cause these symptoms due to a disturbed airflow. Numerical simulations offer a great potential to avoid these limitations and to provide valid data. The aim of the study was to simulate the humidification and heating of the inhaled air in digital nose models with three different SPs and without SP. Four realistic bilateral nose models based on a multi-slice CT scan were created. The SP were located anterior caudal, anterior cranial and posterior caudal. One model was without SP. A numerical simulation was performed. Boundary conditions were based on previous in vivo measurements. Heating and humidification of the inhaled air were displayed, analyzed in each model and compared to each other. Anterior caudal SPs cause a disturbed decrease of temperature and humidity of the inhaled air. The reduced temperature and humidity values can still be shown in the posterior nose. The anterior cranial and the posterior caudal perforation have only a minor influence on heating and humidification. A reduced humidification and heating of the air can be shown by numerical simulations due to SP depending on their localization. The anterior caudal SP representing a typical localization after previous surgery has the biggest influence on heating and humidification. The results explain the typical symptoms such as crusting by drying-out the nasal mucosa. The size and the localization of the SP are essential for the symptoms.

The effect of "Pyriform Turbinoplasty" on nasal airflow using a virtual model.

BACKGROUND: A new procedure, pyriform turbinoplasty, is described and nasal airflow is measured before and after this procedure in a virtual model. METHODOLOGY: Pyriform turbinoplasty is the submucosal reduction of the bone of the frontal process of the maxilla and the lacrimal bone. It opens part of the lateral margin of the nasal valve area with minimal damage to nasal mucosa. The resection of bone in this area can be extended by "nasal wall lateralization" when the lacrimal bone that joins the uncinate process behind the lacrimal duct as well as the base of the inferior turbinate and the edge of the maxilla at the rim of the pyriform aperture are removed. Nasal airflow was simulated using computational fluid dynamics and ANSYS Fluent solver. RESULTS: Analysis using fluid dynamics showed that these procedures help ventilation in the main airflow areas without substantially altering the normal pattern of airflow. CONCLUSIONS: The changes after performing a pyriform turbinoplasty seem to be an improvement when compared to the changes after inferior turbinate surgery that can misdirect the airflow largely through the inferior meatus.

Numerical simulation and nasal air-conditioning.

Heating and humidification of the respiratory air are the main functions of the nasal airways in addition to cleansing and olfaction. Optimal nasal air conditioning is mandatory for an ideal pulmonary gas exchange in order to avoid desiccation and adhesion of the alveolar capillary bed. The complex three-dimensional anatomical structure of the nose makes it impossible to perform detailed in vivo studies on intranasal heating and humidification within the entire nasal airways applying various technical set-ups. The main problem of in vivo temperature and humidity measurements is a poor spatial and time resolution. Therefore, in vivo measurements are feasible only to a restricted extent, solely providing single temperature values as the complete nose is not entirely accessible. Therefore, data on the overall performance of the nose are only based on one single measurement within each nasal segment. In vivo measurements within the entire nose are not feasible. These serious technical issues concerning in vivo measurements led to a large number of numerical simulation projects in the last few years providing novel information about the complex functions of the nasal airways. In general, numerical simulations merely calculate predictions in a computational model, e.g. a realistic nose model, depending on the setting of the boundary conditions. Therefore, numerical simulations achieve only approximations of a possible real situation. The aim of this review is the synopsis of the technical expertise on the field of in vivo nasal air conditioning, the novel information of numerical simulations and the current state of knowledge on the influence of nasal and sinus surgery on nasal air conditioning.

The impact of septorhinoplasty and anterior turbinoplasty on nasal conditioning.

BACKGROUND: Septorhinoplasty and turbinoplasty is a frequently performed operation in facial plastic surgery. The aim of this study was to investigate nasal conditioning after septorhinoplasty and inferior turbinoplasty in patients with internal and external nasal deformities and hypertrophy of the inferior turbinates and to determine its relation to nasal patency. METHODS: Ten patients and 10 volunteers as controls were enrolled into this study. Measurement of nasal conditioning and active anterior rhinomanometry were performed before and 4-6 months after functional-esthetic septorhinoplasty and inferior turbinoplasty. RESULTS: Nasal airflow was significantly higher postoperatively than preoperatively. The preoperative nasal temperature (TEMP) and heat increase (HI) was lower in the patients compared with the controls. The postoperative TEMP, HI, total water content, and water gradient were significantly higher than the preoperative values. CONCLUSION: Based on this relatively small series, functional-esthetic septorhinoplasty in combination with inferior turbinoplasty may be associated with improved nasal conditioning.

Simultaneous in vivo measurements of intranasal air and mucosal temperature.

Nasal cavity volume and blood temperature along the nasal airways, reflecting the mucosal temperature, are considered to be the most important predictors of nasal air conditioning. The purpose of this study was to simultaneously in vivo measure intranasal air as well as mucosal temperature for the first time. Fifteen healthy subjects were enrolled into the study. Two combined miniaturized thermocouples were used for simultaneous recording of intranasal air and mucosal temperature within the anterior turbinate area close to the head of the middle turbinate without interruption of nasal breathing. The highest air and mucosal temperature values were detected at the end of expiration, the lowest values at the end of inspiration. The difference was statistically significant (P < 0.05). The mean mucosal temperature ranged from 30.2 +/- 0.9 to 32.2 +/- 0.8 degrees C. The mean air temperature ranged from 28.5 +/- 1.2 to 34.1 +/- 0.7 degrees C. The mean differences between air and mucosal temperature were 1.7 +/- 0.5 degrees C after inspiration and 1.9 +/- 0.7 degrees C after expiration. Simultaneous measurements of intranasal air and mucosal temperature are practicable. The detected temperature gradient between air and mucosa confirm a relevant heat exchange during inspiration and expiration. This gradient between air and mucosa is obligatory for heat and water exchange to ensure adequate nasal air conditioning.

Video-endoscopy and digital image analysis of the nasal valve area.

The aim of this study was to evaluate the benefit of digital image analysis of video-endoscopic images of the valve area to study changes in cross-sections of the nasal valve area before and after nasal surgery. Fifty patients scheduled for septoplasty or septorhinoplasty were included. Successful recordings of the valve area and digitally calculated cross-sections of the nasal valve area served as main outcome measures. First, various endoscopes (rigid 0 degrees - and 25 degrees -endoscopes and fibreoptic 0 degrees -endoscope) were tested and video-endoscopy was standardised in 39 patients. Second, preoperative and postoperative images of the nasal valve area in 11 patients with obstruction of the nasal valve area were digitally analysed and compared. In these patients, a significant widening of the valve area could be shown postoperatively. We conclude that digital image analysis of the nasal valve area can be helpful in the measurement of cross-sections of the nasal valve area before and after nasal surgical procedures in selected patients.

Impact of resection of the turbinates and the lateral nasal wall on particle deposition.

OBJECTIVES/HYPOTHESIS: The aim of the investigation was to determine the influence of complete resection of the turbinates and the lateral nasal wall on nasal deposition of particulate matter with an aerodynamic diameter of 10 microm or less (pm10) and its relation to nasal patency and geometry. STUDY DESIGN: Retrospective study. METHODS: Eight patients were enrolled in the study after unilateral sinus surgery for a unilateral inverted papilloma of the sinuses. Particle deposition from the inhaled and exhaled air was measured by means of a laser particle counter in the nasal valve area and the nasopharynx during nose-only breathing and nose-in, mouth-out breathing. The data on deposited fraction for the operated side were compared with the data for the untreated, healthy side. Rhinomanometry and acoustic rhinometry were performed. RESULTS: Particle deposition did not differ significantly between the operated and untreated sides of the nose at both detection sites. No correlation between the deposited fraction and rhinomanometric and rhinometric values was found. CONCLUSION: Radical resection of the turbinates does not seem to disturb particle deposition (pm10) measured in the nose to a significant degree. Factors other than impaction and sedimentation onto the mucosal surface of the turbinates seem to be sufficient for effective particle deposition after radical removal of the turbinates.

Healing of composite chondrocutaneous auricular grafts covered by skin flaps in nasal reconstructive surgery.

OBJECTIVE/HYPOTHESIS: Healing of composite chondrocutaneous auricular grafts combined with overlying skin flaps for reconstruction of the internal lining in partial nasal defects should be evaluated. STUDY DESIGN: A retrospective chart review and prospective clinical follow-up of 15 patients with partial nasal defects. METHODS: Fifteen patients with partial defects of the middle and lower third of the nose were reviewed. Nineteen composite ear grafts were used for reconstruction of the internal nasal lining in the patient group. The composite grafts were used in combination with overlying nasolabial transposition flaps. In some patients paramedian forehead or turn-in flaps were needed as well. Functional and aesthetic results of nasal reconstruction were subjectively graded by the patients and medical doctors of the department. RESULTS: Three of 19 transplanted composite grafts showed postoperative deformation. Relative shrinkage was observed in 5 of 19 composite grafts, whereas complete loss of the composite graft was seen in only one patient. Nasal airway obstruction was observed in the patients with deformity or loss of composite graft (4 of 15 patients), and an unsuccessful aesthetic result was seen only in the patient with total composite graft failure (1 of 19 transplanted grafts). CONCLUSIONS: Composite ear grafts may provide good functional and aesthetic results when combined with overlying skin flaps in reconstruction of partial nasal defects. Even though composite ear grafts used for restoration of the inner nasal lining may be deformed or absorbed and impairment of nasal airway patency or aesthetic result may be postoperatively observed, the combination of composite ear grafts with locoregional transposition flaps provides additional reconstructive options for selected nasal defects.

Impact of unilateral sinus surgery with resection of the turbinates by means of midfacial degloving on nasal air conditioning.

OBJECTIVE/HYPOTHESIS: One of the most important functions of the nose is the climatization of inspired air. The aim of the investigation was to determine the influence of radical sinus surgery with complete resection of the turbinates and the lateral nasal wall by means of midfacial degloving as treatment for inverted papilloma on the nasal humidification and heating of inspired air. STUDY DESIGN: Retrospective study. METHODS: Humidity and temperature were measured in the nasopharynx during normal respiration by means of a miniaturized thermocouple device and a humidity sensor for continuous detection. Eight patients after prior unilateral sinus surgery by means of midfacial degloving for a one-sided inverted papilloma were enrolled into the study. The humidity and temperature data of the surgically treated side were compared to the values of the healthy side that was not surgically treated. Active anterior rhinomanometry and acoustic rhinometry were performed. RESULTS: At the end of inspiration, absolute humidity and temperature values in the nasopharynx were statistically significantly lower on the surgically treated side compared with the side that was not surgically treated. CONCLUSIONS: Radical sinus surgery with resection of the turbinates by means of midfacial degloving seems to disturb the climatization of the inspiratory air in the nasal cavity. Reduced absolute humidity and temperature may contribute to crusting, bleeding, and nasal dryness as frequent complaints of patients after aggressive sinus surgery with resection of the turbinates.
