This prospective observational study analyzed conchal regrowth after laser-assisted turbinectomy (LATE) in brachycephalic dogs and the mucosal contact of regrown conchae. Eighty brachycephalic dogs (41 pugs, 39 French bulldogs [FBs]) that underwent LATE because of obstructing conchae were evaluated by endoscopy 7 days and 6 mo after surgery. At 6 mo, 96% of FBs' and 65% of pugs' nasal cavities showed regrowth of turbinates. FBs showed higher growth grades than pugs. Revision surgery because of reobstructing regrowth was required in the nasal cavities of 17% of FBs and 3% of pugs. The mean number of contact points reduced from 3.0 in FB and 1.7 in pugs before surgery to 1.2 in FB and 0.2 in pugs after conchal regrowth. Recollapse of nares after surgery significantly influenced the frequency of reoccurrence of contact points. LATE was proven to be an effective treatment of intranasal obstruction caused by mucosal contact between conchae. Conchal regrowth commonly occurs after surgical removal, but the new conchae cause less obstruction due to a significant reduction in number of contact points. Revision surgery because of reobstruction is rarely necessary. The important physiologic functions of conchae make nonobstructing regrowth desirable.
这项前瞻性观察性研究分析了短头犬激光辅助鼻甲切除术（LATE）后鼻甲的再生情况以及再生鼻甲的黏膜接触情况。对80只因鼻甲阻塞而接受LATE手术的短头犬（41只哈巴狗，39只法国斗牛犬[FBs]）在术后7天和6个月通过内窥镜进行评估。在6个月时，96%的法国斗牛犬和65%的哈巴狗鼻腔出现鼻甲再生。法国斗牛犬的生长等级高于哈巴狗。17%的法国斗牛犬和3%的哈巴狗鼻腔因再生阻塞需要进行翻修手术。接触点的平均数量从术前法国斗牛犬的3.0个和哈巴狗的1.7个减少到鼻甲再生后法国斗牛犬的1.2个和哈巴狗的0.2个。术后鼻孔重新塌陷显著影响接触点复发的频率。LATE被证明是治疗鼻甲间黏膜接触引起的鼻内阻塞的有效方法。手术切除后鼻甲再生常见，但新的鼻甲由于接触点数量显著减少，阻塞性降低。因再次阻塞而进行翻修手术很少有必要。鼻甲重要的生理功能使得无阻塞性再生是可取的。
