Brazilian Journal of Otorhinolaryngology , 2009, DOI: 10.1590/S1808-86942009000400008
Abstract: vocal alterations after thyroidectomy are generally related to laryngeal nerve injury or laryngotracheal mobility disorders caused by postoperative fibrosis or strap muscle lesion. aim: this study aims to evaluate the frequency of vocal and rima glottidis disorders after thyroidectomy. materials and method: this is a prospective study based on 35 patients submitted to thyroidectomy under local anesthesia and hypnosedation. all patients underwent voice auditory perception evaluation, voice acoustic tests and videolaryngostroboscopy preoperatively, and at one week and at 30 days postoperatively. bilateral cricothyroid muscle electromyography was performed on the thirtieth day after surgery to confirm the presence of injury in the external branch of the superior laryngeal nerve. results: 14.3% of the patients presented posterior glottis deviation before surgery and normal electromyography findings. transient and permanent vocal alteration occurred in 25.7% and 14.2% of the patients respectively. conclusion: voice disorders evaluated after voice auditory perceptive evaluation and voice acoustic tests were more intense in the group with superior laryngeal nerve external branch injury than in the injury-free dysphonic patient group. oblique glottis can be present in normal patients; however its onset after thyroidectomy is indicative of superior laryngeal nerve external branch lesion.

Brazilian Journal of Otorhinolaryngology , 2013,
Abstract: Arela o anat mica entre seio maxilar e ducto lacrimonasal adquiriu maior importancia com o advento das microcirugias e cirurgias nasossinusais assistidas por endoscopia e pelo crescente uso da endoscopia nasal na realiza o das meatotomias médias e dacriocistorrinostomiastransnasais. N o foram encontrados relatos de classifica o do seio maxilar quanto ao seu recesso lacrimal, tampouco sua frequência. OBJETIVO: Avaliar a frequência do recesso lacrimal do seio maxilar em pe as anat micas dissecadas. MéTODO: Foram avaliadas 31 partes de hemicabe as de cadáveres. Procedeu-se à dissec o da área correspondente ao ter o médio da face, por acesso lateral, para que se pudesse observar a posi o da por o mais lateral do ducto lacrimonasal em rela o ao seio maxilar. Os seios maxilares foram avaliados, por dois examinadores simultaneamente, chegando ao consenso do tipo de ducto lacrimonasal. RESULTADOS: Foram encontrados 18 seios maxilares do tipo lateral (58,1%) e 13 do tipo anterior (41,9%). A diferen a entre a frequência de seios maxilares do tipo anterior nos lados direito (35,7%) e esquerdo (47,1%) n o mostrou significancia estatística (p = 0,524). CONCLUS O: Observou-se frequência de 41,9% de recessos lacrimais nos seios maxilares. The anatomical relation between the maxillary sinus and the nasolacrimal duct has gained greater importance with the advent of microsurgeries and endoscopic-assisted sinonasal procedures, and the growing use of endonasal surgery to perform middle meatus procedures and transnasal dacryocystorhinostomy. We did not find reports on maxillary sinus classification concerning its lacrimal recess, nor how often it is found. OBJECTIVE: To assess how frequent the lacrimal recess can be found in the maxillary sinuses of dissected anatomical specimens. METHOD: We assessed 31 half-heads from cadavers. We dissected the area corresponding to the middle third of the face, by lateral access so as to be able to observe the most lateral portion of the nasolacrimal duct vis-à-vis the maxillary sinus.The maxillary sinuses were assessed by two examiners simultaneously, getting to a consensus in relation to the type of nasolacrimal duct. RESULTS: We assessed 18 maxillary sinuses of the lateral type (58.1%) and 13 anterior sinuses (41.9%). The difference in frequency of the anterior type of maxillary type of the right side (35.7%) and left (47.1%) did not have statistical significance (p = 0.524). CONCLUSION: We found a frequency of 41.9% of lacrimal recesses in the maxillary sinuses.
