Correção de fenda palatina secundária traumática em cão - relato de caso / Correction cleft palate secondary traumatic in dog - case report

A fenda palatina é a comunicação entre a cavidade oral e a nasal através de um orifício no palato. Tem diversas etiologias, podendo ser congênita, traumática, por deficiência mineral ou por fatores hormonais. O diagnóstico é realizado por meio de exame físico da cavidade oral, e a correção cirúrgica é o tratamento de escolha. Em animais adultos, pode ser corrigida com o auxílio de retalho mucoperiosteal, apresentando bons resultados. Já em filhotes, a correção cirúrgica é mais complicada, com prognóstico menos favorável. Este trabalho relata o caso de um canino, fêmea, sem raça definida, adulta, com histórico de fenda palatina secundária, de origem traumática, no palato mole por ingestão de osso. Para a correção cirúrgica, primeiramente foi utilizada membrana biológica de pericárdio bovino, mas não se obteve êxito. O segundo procedimento foi realizado com retalho mucoperiosteal simples autólogo e, dois meses após o procedimento, já havia cicatrização completa. A técnica de retalho mucoperiosteal simples autólogo se mostrou eficaz no tratamento da fenda palatina, aliada aos cuidados adequados no pós-operatório.(AU)

The cleft palate is the communication between the oral and nasal cavity through an aperture in the palate, it's causes include an infinitude of factors: congenital, traumatic, mineral deficiency or hormonal. Examination of the oral cavity determines if the diagnosis and treatment is surgical. Correction in adult animals is performed with mucoperiosteal flap showing good results. However, surgical correction in puppies is more complicated with less favorable prognosis. This current work reports a case of an adult, female dog of undefined breed, with a history of secondary clef palate of traumatic origin in the soft palate due to bone ingestion. For correction, a biological membrane of bovine pericardium was used, but it was not successful, requiring a second surgical procedure performed with autologous simple mucoperiosteal flap. The last technique combined with adequate postoperative care was effective.(AU)

Platelet-Rich Fibrin a Second Generation Autologous Platelet Concentrate for the Treatment of Inadequate Width of Attached Gingiva.

Along with the better understanding of the pathogenesis of periodontal diseases, the treatment modalities for various periodontal diseases have also gone a step ahead. One of the most important and currently unsolved problems in clinical periodontics is the predictable successful treatment of inadequate width of attached gingiva. Recently, importance has been given to the use of platelet-rich fibrin (PRF) for predictably treating periodontal diseases. PRF is an intimate assembly of glycan chains, glycoproteins, and cytokines. These are enmeshed in a slowly polymerized fibrin network which has the potential to accelerate soft and hard tissue healing. This article presents the clinical results of treatment of inadequate width of attached gingiva with PRF.

Preservation of palatal mucoperiosteum for oronasal separation after total maxillectomy.

Background: Oronasal communication occurs after total maxillectomy for advanced sinonasal cancers. This results in feeding, breathing and cosmetic impairment. Various methods have been described to close off the palatal defect from the oral cavity to improve the function of speech and deglutition. Aims: The object of this article is to describe our experience of preservation of palatal mucoperiosteum for oronasal separation. Materials and Methods: Retrospective review of clinical and operative records of 31 total maxillectomy patients where oronasal separation was achieved by the conventional technique of applying a maxillary obturator. The postoperative complications arising from the use of maxillary obturator for oronasal communication after total maxillectomy in these 31 patients were analysed. To avoid the complications encountered in these 31 patients we preserved and used the ipsilateral palatal mucoperiosteum for oronasal separation. This new technique was applied in 12 patients. The results are presented and compared. Results : A total of 43 patients underwent total maxillectomy for advanced sinonasal tumors. In 31 patients the conventional maxillary obturator was used for oronasal separation. Among these patients, 30 had crustation of the maxillary cavity, nasal regurgitation and cheek skin retraction in 15 each, trismus in eight, infection of skin graft donor site in seven, cheek movement during respiration in five and ill-fitting prosthesis in three. In 12 patients palatal mucoperiosteum was preserved and used for oronasal separation. The complications encountered in oronasal separation by palatal prosthesis were avoided in the modified procedure. Conclusions: We found that oronasal separation by preservation of palatal mucoperiosteum following total maxillectomy allowed excellent palatal function, prompt rehabilitation and minimal complications without compromising the prognosis.

Repairing incomplete cleft palate with double island mucoperiosteal flap / 实用口腔医学杂志

Objective:To evaluate the effects of repairing incomplete c left palate with double island mucoperiosteal flap. Methods:Inco mplete cleft palate was repaired with double island mucoperiosteal flap in 12 ca ses. Two island mucoperiosteal flaps were transferred to the oral side and nasal side of soft palate respectively to prolong soft palate. After operation the pa tients were followed up for 3~6 months,the vitality of the flaps, the degree of prolonged soft palate and the change of vocalization were surveyed. Resu lts:All transferred flaps were survived. No complications like perforati on, cleft recurrance, infection, necrosis etc happened. The soft palate was prol onged obviously in all cases. Vocalization of the patients was improved to a cer tain degree. Conclusions:Double island mucoperiosteal flap is fe asible in the repair of incomplete cleft palate.

Simultaneous septorhinoplasty / 中华医学美学美容杂志

Objective To introduce a new septorhinoplastic method for twisted nose, humped nose and hawk nose as well as deviation of nasal septum, and to evaluate its operative method and effect. Methods The incision of cleft between lateral nasal cartilage and greater alar cartilage was employed in all patients. The method of unilateral mucoperiosteal flap osteotomy was used to correct nasal pyramid deformity, and swinging-door operation was performed to correct the deviation of nasal septum simultaneously. Results The operative results of 36 cases were effective and satisfactory. Postoperative follow-up ranged from one year to fifteen years. Based on the results of follow-up in the 32 cases, no recurrence and complications were found in all the cases. Conclusion This new method for septorhinoplasty avoids the detachment and move of nasal bone and nasal septum cartilage and injury of nasal mucoperiosteum, and maintains the blood supply of nasal bone and nasal septum cartilage. It corrects extero-nasal deformity as well as deviation of nasal septum. The operation is effective in nose aesthetic and ventilatory function.
