RESUMO
Abstract Introduction Septal deviation is a common disease seen in daily otorhinolaryngology practice and septoplasty is a commonly performed surgical procedure. Caudal septum deviation is also a challenging pathology for ear, nose, and throat specialists. Many techniques are defined for caudal septal deviation. Objective To evaluate the effectiveness of caudal septal extension graft (CSEG) application in patients who underwent endonasal septoplasty for a short and deviated nasal septum. Methods Forty patients with nasal septal deviation, short nasal septum, and weak nasal tip support who underwent endonasal septoplasty with or without CSEG placement between August 2012 and June 2013 were enrolled in this study. Twenty patients underwent endonasal septoplasty with CSEG placement. The rest of the group, who rejected auricular or costal cartilage harvest for CSEG placement, underwent only endonasal septoplasty without any additional intervention. Using the Nasal Obstruction Symptom Evaluation (NOSE) and Rhinoplasty Outcome Evaluation (ROE) questionnaires, pre- and post-operative acoustic rhinometer measurements were evaluated to assess the effect of CESG placement on nasal obstruction. Results In the control group, preoperative and postoperative minimal cross-sectional areas (MCA1) were 0.44 ± 0.10 cm2 and 0.60 ± 0.11 cm2, respectively (p < 0.001). In the study group, pre- and postoperative MCA1 values were 0.45 ± 0.16 cm2 and 0.67 ± 0.16 cm2, respectively (p < 0.01). In the control group, the nasal cavity volume (VOL1) value was 1.71 ± 0.21 mL preoperatively and 1.94 ± 0.17 mL postoperatively (p < 0.001). In the study group, pre- and postoperative VOL1s were 1.72 ± 0.15 mL and 1.97 ± 0.12 mL, respectively (p < 0.001). Statistical analysis of postoperative MCA1 and VOL1 values in the study and the control groups could not detect any significant intergroup difference (p = 0.093 and 0.432, respectively). In the study group, mean nasolabial angles were 78.15 ± 4.26º and 90.70 ± 2.38º, respectively (p < 0.001). Conclusion Endonasal septoplasty with CESG placement is an effective surgical procedure with minimal complication rate for subjects who have a deviated, short nasal septum and weak nasal tip support.
Resumo Introdução Desvio septal é doença comum no cotidiano da prática otorrinolaringológica e a septoplastia é procedimento cirúrgico comum. Desvio caudal do septo nasal é também uma condição desafiadora para os otorrinolaringologistas. São muitas as técnicas definidas para desvio caudal do septo nasal. Objetivo Avaliar a eficácia da aplicação de enxerto de extensão septal caudal (EESC) em pacientes que passaram por septoplastia endonasal devido a septo nasal curto e com desvio. Método Foram recrutados para o estudo 40 pacientes com desvio de septo nasal, septo nasal curto e fraca sustentação da ponta do nariz, tratados com septoplastia endonasal com ou sem a aplicação de EESC, entre agosto de 2012 e junho de 2013. Ao todo, 20 pacientes foram tratados com septoplastia endonasal com aplicação de EESC. O restante do grupo, que rejeitou coleta de cartilagem auricular ou costal para a aplicação de EESC, foi tratado apenas com septoplastia endonasal. Com a aplicação dos questionários Nose (Nasal Obstruction Symptom Evaluation, Avaliação dos Sintomas de Obstrução Nasal) e ROE (Rhinoplasty Outcome Evaluation, Avaliação dos Desfechos da Rinoplastia), as mensurações pré e pós-operatórias com o rinômetro acústico foram obtidas com o objetivo de avaliar o efeito da aplicação de EESC na obstrução nasal. Resultados No grupo controle, as áreas de secção transversal mínima (ASTM1) antes e depois da operação foram 0,44 ± 0,10 cm2 e 0,60 ± 0,11 cm2, respectivamente (p < 0,001). No grupo de estudo, os valores antes e depois da operação para ASTM1 foram 0,45 ± 0,16 cm2 e 0,67 ± 0,16 cm2, respectivamente (p < 0,01). No grupo controle, o valor para os volumes da cavidade nasal (VOL1) foi 1,71 ± 0,21 mL no pré-operatório e 1,94 ± 0,17 mL no pós-operatório (p < 0,001). No grupo de estudo, os VOL1 antes e depois da operação foram 1,72 ± 0,15 mL e 1,97 ± 0,12 mL, respectivamente (p < 0,001). A análise estatística dos valores pós-operatórios para ASTM1 e VOL1 nos grupos de estudo e controle não permitiu a detecção de qualquer diferença intergrupos (p = 0,093 e 0,432, respectivamente). No grupo de estudo e no grupo controle, os ângulos nasolabiais médios foram 78,15 ± 4,26º e 90,70 ± 2,38º, respectivamente (p < 0,001). Conclusão A septoplastia endonasal com aplicação de EESC é um procedimento cirúrgico efetivo, com mínimo percentual de complicações para pacientes que se apresentam com septo nasal curto e com desvio e com fraca sustentação da ponta do nariz.

HYPOTHESIS: Tacrolimus helps healing of facial nerve injury. BACKGROUND: Positive effects of tacrolimus on axon regeneration and healing of injured peripheral nerves (eg. sciatic nerve) have been reported in the literature. Tacrolimus may be an additional treatment method that could improve the nerve healing after surgical treatment of cut injury of facial nerve. METHODS: 20 New Zealand rabbits were randomly separated into control and study groups of 10. In control group, no medical treatment was given after facial nerve anastomosis, and the animals were followed up for 2months. In the study group rabbits were given 1mg/kg/day tacrolimus subcutaneously for 2months after the facial nerve anastomosis. The histopathologic findings of axon regeneration like axon myelination were analyzed in both groups under electron and light microscopy. The data obtained in the groups were compared. RESULTS: Greater axon diameters, thicker myelin sheaths, and higher total number of myelinated axons were found in the tacrolimus group, suggesting better regeneration in this group when compared to the control group. There was less vacuolar degeneration in the study group. All these findings suggest that tacrolimus positively affects healing after facial nerve anastomosis. CONCLUSION: The results of this study indicate that tacrolimus has favorable effects on the healing process of the facial nerve after end-to-end anastomosis. Tacrolimus may be a promising agent in the future for nerve regeneration following traumatic facial paralysis surgery.
