Is there a relationship between middle concha bullosa and ethmoid roof asymmetry? / Existe uma relação entre a concha média bolhosa e a assimetria do teto etmoidal?

Abstract Introduction The middle turbinate and ethmoid roof are intranasal structures and may have many anatomical variations. These structures, which serve as anatomical markers during functional sinus surgery, are important for preventing complications and performing a proper surgery. Knowledge of anatomical variations will increase surgical success and reduce complications. Objective We aimed to investigate the presence of asymmetry in the ethmoidal roof and anatomical variation in patients with and without concha bullosa. Methods In this study, the files of patients who underwent paranasal computed tomography between 2012 and 2018 were analyzed retrospectively. The patients were divided into two groups, as patients with and without concha bullosa. Differences between the two groups in terms of age, gender, septum deviation, ethmoid artery dehiscence, ethmoid roof asymmetry were examined. Results The 369 patients included in our study were divided into two groups; those with concha bullosa and those without concha bullosa. The mean age of the patients with concha bullosa was 36.1 ± 13.4 (min-max: 12-74) and the mean age of patients without concha bullosa was 37.5 ± 14.3 (min-max: 10-81). The ethmoid roof depths were compared between the two groups and a significant difference was observed (p < 0.001). The ethmoid roof depth was higher in the group with concha bullosa (p < 0.001). Conclusion The results of our study indicate that the ethmoidal roof tends to be higher in patients with middle concha bullosa.

Resumo Introdução A concha média e o teto etmoidal são estruturas intranasais e podem apresentar muitas variações anatômicas. Essas estruturas, usadas como marcadores anatômicos durante a cirurgia sinusal funcional, são importantes para evitar complicações e para a feitura adequada da cirurgia. O conhecimento das variações anatômicas aumenta o sucesso cirúrgico e reduz as complicações. Objetivo Investigar a presença de assimetria no teto etmoidal e variações anatômicas em pacientes com e sem concha bolhosa. Método Os prontuários dos pacientes submetidos à tomografia computadorizada de seios paranasais entre 2012 e 2018 foram analisados retrospectivamente. Os pacientes foram divididos em dois grupos, pacientes com e sem concha bolhosa. As diferenças entre os dois grupos em termos de idade, sexo, desvio do septo, deiscência da artéria etmoidal e assimetria do teto etmoidal foram avaliadas. Resultados Os 369 pacientes incluídos em nosso estudo foram divididos em dois grupos: com concha bolhosa e sem concha bolhosa. A média de idade dos pacientes com concha bolhosa foi de 36,1 ± 13,4 (mín-máx: 12-74 anos) e a média de idade dos pacientes sem concha bolhosa foi de 37,5 ± 14,3 (mín-máx: 10-81 anos). As profundidades do teto etmoidal foram comparadas entre os dois grupos, observou-se diferença significante (p < 0,001). Observou-se que a profundidade do teto etmoidal foi maior no grupo com concha bolhosa (p < 0,001). Conclusão O resultado do nosso estudo indica que pacientes com concha média bolhosa tendem a apresentar uma maior profundidade do teto etmoidal.

Is there a relationship between middle concha bullosa and ethmoid roof asymmetry?

INTRODUCTION: The middle turbinate and ethmoid roof are intranasal structures and may have many anatomical variations. These structures, which serve as anatomical markers during functional sinus surgery, are important for preventing complications and performing a proper surgery. Knowledge of anatomical variations will increase surgical success and reduce complications. OBJECTIVE: We aimed to investigate the presence of asymmetry in the ethmoidal roof and anatomical variation in patients with and without concha bullosa. METHODS: In this study, the files of patients who underwent paranasal computed tomography between 2012 and 2018 were analyzed retrospectively. The patients were divided into two groups, as patients with and without concha bullosa. Differences between the two groups in terms of age, gender, septum deviation, ethmoid artery dehiscence, ethmoid roof asymmetry were examined. RESULTS: The 369 patients included in our study were divided into two groups; those with concha bullosa and those without concha bullosa. The mean age of the patients with concha bullosa was 36.1 ±â€¯13.4 (min-max: 12-74) and the mean age of patients without concha bullosa was 37.5 ±â€¯14.3 (min-max: 10-81). The ethmoid roof depths were compared between the two groups and a significant difference was observed (p < 0.001). The ethmoid roof depth was higher in the group with concha bullosa (p < 0.001). CONCLUSION: The results of our study indicate that the ethmoidal roof tends to be higher in patients with middle concha bullosa.

Recurrence of Giant Cell Tumor of The Larynx.

Giant cell tumor of the larynx is a rare tumor. It was first reported by Wessely et al in 1940. Thirty-nine cases have been reported until now and together with the current case 2 recurrences were encountered. In this case report, our aim was to discuss conservative management because of the suspicion of recurrence. A 70-year-old male patient was admitted to our clinic with the complaint of hoarseness. A tumor measuring 1 × 1 cm located in the anterior half right vocal fold and extending to the anterior comissure was found on laryngeal endoscopy. Direct laryngoscopy and biopsy of the mass revealed giant cell tumor on histopathological examination. Tumor resection with cordectomy through laryngofissure and subsequently medialization thyroplasty were performed. Horaseness of the patient improved. On 2-year follow-up, a tumoral lesion suggesting recurrence was found on the vocal cord. Direct laryngoscopy and biopsy confirmed recurrence. Total laryngectomy was performed. This is the second case of recurrent giant cell tumor of the larynx. The therapy of choice should be selected considering the possibility of recurrence.
